Asilidae

Leptogaster cylindrica, copyright Fritz Geller-Grimm.


Belongs within: Asiloidea.
Contains: Dioctriinae, Stenopogoninae, Laphriinae, Dasypogoninae, Apocleinae, Asilinae.

The Asilidae, robber flies, are a group of predatory flies characterised by a moustache of bristles across the lower margin of the face. They are divided between several subfamilies including the Leptogastrinae which are slender-bodied robber flies lacking alulae or pulvilli. The Trigonomiminae are generally small flies with large 'goggle-eyes' and lacking strong bristles on the thorax. The cosmopolitan, primarily arboreal Ommatius has a long, plumose apical flagellomere on the antenna and closed cell r1 in the wing (Fisher 2009).

Characters (from Wood 1981): Small (3 mm) to very large (over 50 mm) flies, averaging 9-15 mm in length, long and slender to short, robust, and bee-like. Head with compound eyes large, usually widely separated, equally so in both sexes; eye facets enlarged medially; eye extending dorsally above level of vertex, causing vertex to appear excavated when viewed anteriorly; ocellar tubercle prominent; median ocellus enlarged; vestiture of ocellar tubercle of fine pile, often mixed with bristles. Face extensively developed, often convexly protuberant (gibbous); facial protuberance, or gibbosity, with a characteristic group of stout anteroventrally directed hairs or bristles, the mystax, arranged as a cluster on lower part of face. Clypeus reduced, concave or flat, folded posteroventrally below lower facial margin. Antenna held erect; scape and pedicel each usually with long or short pile, often with stout bristles; first flagellomere elongate or oval, pubescent or tomentose but without pile or bristles, usually longer than either scape or pedicel. Bent apical or subapical stylus usually present on first flagellomere, typically two-segmented, occasionally one-segmented, apparently absent in Laphriinae. A minute spine, often in a pit, present at apex of antenna on either first or succeeding flagellomeres. Mouthparts adapted for stabbing and sucking prey. Mandible absent; stabbing function performed by needle-like hypopharynx that injects a paralyzing saliva. Proboscis elongate, heavily sclerotized, formed from ventromedial fusion of prementum and labella as continuous tube open at apex and dorsomedially, enclosing maxillae and hypopharynx; tip of labella pointed or rounded, usually surrounded with sensory hairs; ventral surface of labella and most of prementum pilose. Palpus usually slender or clavate, setose. Thorax with notopleural, supra-alar, and postalar bristles almost always present; dorsocentral bristles usually present. Scutellum usually pruinose but sometimes shiny, almost always with hairs or bristles along its margin especially at apex; katatergite almost always with a row or group of bristles. Legs raptorial, stout, frequently with numerous stour bristles; all tibiae with several stout bristles at apices. Wing venation with R always four-branched, with R2+3 unbranched. Abdomen with dight segments usually present in both male and female, with remaining two segments incorporated into terminalia. Larva elongate, subcylindrical to somewhat dorsoventrally flattened, often tapering at each end; colour white to yellowish, sometimes with a few fine longitudinal streaks. Head capsule much narrower than prothorax, usually exerted, directed ventrally. Nine abdominal segments apparently present, with eighth and ninth partly fused; length of segments increasing toward seventh. Respiratory system functionally amphipneustic, although vestigial spiracles are present on first seven abdominal segments.

Asilinae

Asilus crabroniformis, copyright António A. Gonçalves.


Belongs within: Asilidae.

The Asilinae are a group of robber flies with a long, bare stylus on the antenna. They are the most diverse subfamily of robber flies in temperate regions of the world but are less diverse in the tropics (Fisher 2009). The larger number of species are assigned to the genus Asilus, including fossils going back to the Eocene (Wood 1981).

Characters (from Wood 1981, as Asilini): Apex of antenna with long slender bristle-like stylus; antennal stylus bare. Palpus one-segmented. Postmetacoxal area membranous. Wing with R2+3 joining R1 proximal to end of R1, with cell r thus separated from wing margin; crossvein m-cu absent, and veins M3 and CuA1 joined together.

Laphriinae

Andrenosoma fulvicaudum, copyright Tom Murray.


Belongs within: Asilidae.
Contains: Atomosini.

The Laphriinae are a group of robber flies lacking a conspicuous stylus on the antenna (Wood 1981). Members of the genus Laphria are particularly large, hairy robber flies that mimic bees in appearance. The Andrenosomatini are characterised by a dorsoventrally strongly flattened proboscis and flat, lamellate palpi, and females bear a cylindrical anal tube formed from the cerci (Fisher 2009).

Characters (from Wood 1981): Antenna blunt apically, without stylus, or with one or two abruptly tapered short microsegments. Palpus two-segmented. Wing with R2+3 joining R1 proximal to end of R1, with cell r thus separated from wing margin; crossvein m-cu present; thus apex of cell bm closed by three veins. Male terminalia rotated 180° permanently.

Stratiomyidae

Barred snout Nemotelus uliginosus, copyright David Gould.


Belongs within: Stratiomyomorpha.
Contains: Stratiomyini, Oxycerini, Sarginae, Clitellariinae, Pachygastrinae.

The Stratiomyidae, soldier flies, are an ecologically diverse group of often colourful flies. Larvae of the Stratiomyinae and Nemotelinae are aquatic whereas larvae of other subfamilies are terrestrial, mostly living in association with decaying plant or animal matter. As adults, the Chiromyzinae are markedly sexually dimorphic, with females much larger than males, and have atrophied mouthparts, an unarmed scutellum and an elongate abdomen. The Beridinae have a similarly elongate abdomen but retain functional mouthparts and usually have six or more marginal spines or tubercles on the scutellum (Woodley 2009).

Characters (from James 1981): Slender to quite robust flies, 2-18 mm long. Colour usually yellow, green, blue, or black, sometimes metallic, frequently with variegated color patterns particularly on abdomen. Bristles not developed, though body, especially thorax, sometimes densely pilose. Head usually as broad as thorax but sometimes broader, hemispherical to spherical. Occipital (postocular) orbit often well-developed, especially in female. Eyes ranging from bare to densely hairy, widely separated in female, more narrowly separated or contiguous in male, each eye in male often divided into an upper area comprising large facets and a lower area of small facets; ocelli present. Antenna inserted at or below middle of head; scape and pedicel unmodified except in respect to elongation; flagellum consisting of five to eight flagellomeres. Proboscis usually fleshy, sometimes atrophied, sometimes elongated, never adapted for sucking blood; palpus one- or two-segmented, not conspicuous.

Head hemispherical, not depressed at vertex. Eyes dichoptic in female, holoptic in most males, usually without hairs in both sexes. Frons of female wide, reaching ocellar tubercle; frons of male usually small, acutely to broadly triangular, pruinose to bare. Three prominent ocelli set at vertex or slightly anterior to vertex. Antenna three-segmented; scape usually setose, especially ventrally; pedicel usually with ring or two of short setae; first flagellomere without setae, or with setae usually confined to basal third; stylus comprising one or two flagellomeres and a terminal or subterminal bristle, set apically or subapically on basal flagellomere. Face often pruinose; lateral area hairy or not; gena hairy or not; occiput finely pruinose; postocular setae usually present though often weak. Palpus one- or two-segmented, usually hairy and not prominent, set beside proboscis in subcranial cavity; proboscis slightly longer than palpus, usually carried within subcranial cavity. Thorax with scutum varying from nearly square to elongate rectangular when viewed from above. Scutellum prominent, often without hairs, but almost always pruinose and often tomentose. Pleuron variously pilose; upper portion usually densely pruinose. Chaetotaxy with one pair postalar setae; one to six pairs notopleural setae, or more; one or two pairs supra-alar setae; usually from zero to two pairs dorsocentral setae, but three or more in a few species; zero to three, rarely four, pairs scutellar setae. Legs usually fairly long and slender; hindleg longer than other two. Fore coxa with none to several setae on anterior surface; all femora bare to heavily setose especially postventrally, often with long scale-like pile along dorsal surface; tibiae and tarsi setulose in definite longitudinal rows; fore tibia lacking setae anteroventrally. Five tarsomeres present; first tarsomere longest; claw with two pulvilli and seta-like central empodium, or with empodium absent. Wing venation generally uniform; R1 setose or not; R4 elongate, often sinuate; cell d elongate, with M1, M2 and M3 arising from apex; CuA1 not meeting posterior margin of cell d; crossvein m-cu present; cell cup closed behind; cell m3 open or closed. Pterostigma usually well-developed. Calypter well-developed. Halter large and well-developed. Abdomen usually convex to flattened dorsally and tapering at apex, sometimes laterally compressed, always with eight well-developed pregenital segments. Fine silvery pollen often adorning abdomen. Tomentum and pile present or absent, usually longer and denser on male. Female terminalia with large conspicuous sternite 8; sternite 9, or genital fork, completely internal, with two lateral sclerites fused posteriorly to sclerotized bar containing membranous central sheath through which pass ducts of spermathecae and accessory glands; three usually unsclerotised spermathecae and two accessory glands present; tergite 8 generally unmodified; tergite 9 usually a single sclerite, generally with extended lateral margins fused to posterolateral margins of genital fork; tergite l0 always divided, often fused with tergite 9; digging-anchoring spines often present posterodorsally and anterolaterally; sternites l0 and ll (hypoproct, subanal plate) usually a single plate, usually heavily sclerotised; cerci disc-shaped. Male terminalia with sclerites forming sternite 8 and tergite 8 unmodified to narrowly constricted; tergite 9 (epandrium) acting as large covering for terminalia, often with surstyli or lateral surstylar-like lobes of various sizes and shapes; hypoproct and cerci borne apically; gonocoxites often extending as broad to narrow lobe well beyond insertion of gonostylus, usually with one or more other appendages; aedeagus consisting of a short to long variously twisted distiphallus, an elongate or vestigial dorsal aedeagal apodeme, a simple or forked ventral apodeme, and a variously shaped ejaculatory apodeme. Larva elongate, cylindrical, tapering anteriorly toward head and apex of abdomen; head small, with cranium well-sclerotised and divided into two portions; anterior portion exposed and strongly tapered anteriorly toward mouthparts; posterior portion a long apically spatulate metacephalic rod, flexibly articulated to posterior dorsal margin of anterior cranial portion and projecting into thorax; mouthparts comprising median slender tapered labrum flanked by curved pointed mandibles, and laciniae and palpi of maxillae, with elements of labium ventrally; labium consisting of large postmentum closing ventral part of cranial cavity, a fused pair of labial palpi usually bearing several pairs of setae, and prementum anteriorly; cranium exteriorly with several sensory cells both dorsally and ventrally, with antennae set in crescent-shaped cups on anterodorsal surface, with one pair of elongate dorsal setae and two pairs of elongate ventral setae, with heavily sclerotized postmentum ventrally, and dorsally with some weakly sclerotized portions called white areas; two pairs of heavy tentorial arms present internally. Thorax with pair of dorsolateral setae on each segment; anterior spiracle distinct, with two or three spiracular openings on specimens examined; abdominal segments l-8 secondarily constricted, giving appearance of two segments each, which with three thoracic segments appear as 19 segments in all; posterior spiracles on antipenultimate segment, apparently with eight spiracular openings; terminal segment ending in pair of retractable finger-like prolegs.

Belongs within: Tabanomorpha.
Contains: Diachlorini, Tabanini, Pangoniini, Scionini, Bouvieromyiini.

The Tabanidae, horse flies, are a group of medium-sized to large flies, females of which commonly feed on vertebrate blood. Males and females of this family are readily distinguished by the eyes being holoptic in males but distinctly separated in females.

Characters (from Pechuman & Teskey 1981): Moderate to large flies, 6-30 mm long, without bristles. Head large; eyes large, often brightly patterned, holoptic in male, separated by frons in female. Antenna porrect and composed of scape, pedicel, and flagellum; flagellum usually consisting of a larger basal portion and terminal annulations usually numbering four to eight but sometimes as few as two. Palpus composed of two segments; basal palpal segment usually rather small; other palpal segment usually rather long and curved downward in female, often inflated near base. Proboscis stout and rigid; mandible and maxilla of female often styliform and adapted for piercing, sometimes absent in species that are not bloodsuckers. Thorax large; notopleural lobe prominent; scutellum without spines or macrotrichia. Legs rather stout; apical spurs present on mid tibia, absent on fore tibia, present or absent on hind tibia; tarsi each with three pads formed by pulvilliform empodium located between two pulvilli. Wing venation with as many as 11 veins reaching margin (Sc, four branches of R, three branches of M, CuA1, CuA2, A1), C extending around wing, cells br, bm, and d conspicuous, and cell cup usually closed near wing margin; calypter large. Abdomen broad, with seven segments usually visible; terminalia of both sexes usually inconspicuous; male with gonocoxites fused with sternite 9, with gonostylus single or partially divided, aedeagus and associated pair of slender filamentous recurved aedeagal tines enclosed in a sheath apparently derived from parameres, tergite 9 entire or divided, tergite l0 absent, cercus flattened, round to oval or somewhat pointed; female usually with tergite l0 divided, with sternite 8 shield-shaped, and with cercus one-segmented. Larva fusiform or more or less expanded posteriorly or anteriorly, comprising 11 body segments and completely retractile head capsule; head capsule elongate, subcylindrical, tapering anteriorly, features including semitubular cranium, paired tentorial arms attached anteriorly to inner dorsal surfaces of cranium and appearing to be free posteriorly, three-segmented antennae, median down-curved labrum, mandibular-maxillary sclerites including maxillary palpi, and labium closing head capsule ventrally; mandibles each with central canal for excretion of paralytic enzyme, linked with subdorsal brushes of spines that are erected to anchor head within host when mandibles strike downward; body without projecting appendages on thoracic segments, with annular rings of small tubercles and crenulate frills or with prolegs on abdominal segments; respiratory system functionally metapneustic.

Stratiomyini

Odontomyia sp., copyright Muhammad Mahdi Karim.


Belongs within: Stratiomyidae.

The Stratiomyini are a group of soldier flies with the antenna lacking an apical stylus, and vein A1 in the wing straight. They may be divided between tribes Stratiomyini sensu stricto and Odontomyiini based on whether the antenna has five (Stratiomyini) or six (Odontomyiini) flagellomeres (James 1981) but this division is not recognised below, following Woodley (2009). Members of the Stratiomyini often resemble bees or wasps and may frequent flowers as adults (Woodley 2009).

Characters (from James 1981, as Stratiomyini + Odontomyiini): Antennal flagellum with five or six flagellomeres, not aristate. Scutellum with spines (sometimes minute). Wing with crossvein m-cu present; cell d present; A1 not at all sinuous. Abdomen at least three-quarters as wide as long, usually patterned.

Ceratopogonidae

Female Leptoconops, copyright Alice Abela.


Belongs within: Culicomorpha.
Contains: Forcipomyia, Culicoidini, Ceratopogonini, Sphaeromiini.

The Ceratopogonidae, biting midges, are a cosmopolitan group of small flies, a number of species of which have females that feed on vertebrate blood. Four subfamilies are recognised, the most divergent of which includes the genus Leptoconops which has eyes widely separated on top of the head (vs closely approximated in other subfamilies) and lacks the crossvein r-m in the wing (Downes & Wirth 1981).

Characters (from Downes & Wirth 1981): Small flies, 1–6 mm long, slender to moderately robust. Antenna with 11–13 flagellomeres, showing marked sexual dimorphism; female with five distal flagellomeres elongated and differing from proximal flagellomeres in many details; male with pedicel greatly enlarged and containing a specialised Johnston's organ, flagellomeres 1–8 usually bearing whorls of long setae giving characteristic plumose appearance. Proboscis about as long as head; palpus slightly longer. Female with biting and sucking mouthparts, consisting of a rigid labrum, blade-like mandibles and laciniae, and a hypopharynx, each typically with apical armature; females in non-biting species and all males with proboscis weaker and armature reduced. Palpus five-segmented; segments 1 and 2 sometimes poorly developed; segment 3 with sensory organ enclosed in a pit or on surface; segments 4 and 5 occasionally fused. Wings held horizontally at rest one above the other, narrower in male than in female; apex evenly rounded. Venation characterized by compact radial system lying closely behind costal margin and meeting margin before apex of wing, often near or even before the midpoint. R1 and Rs typically short, with Rs branching into R2+3, and R4+5; R2+3 running forward and rejoining R1 to form cell r1 (usually termed first radial cell); R4+5 meeting C farther out to form cell r2+3; one or both of these cells sometimes lost either by closure (approximation of upper and lower veins) or by becoming confluent through loss of R2+3. Strong and characteristic crossvein r-m present. Posterior veins relatively weak; M2 sometimes incomplete basally or absent; crossvein m-cu absent; cubital fork well-developed; CuP and A weak, not reaching wing margin. Legs moderately long; claws usually similar, average in size; male with small claws that are usually bifid at tips. Abdomen l0-segmented; spiracles present on segments 2–7; segment 1 somewhat reduced; tergites 1 and 2 sometimes fused. Sternite 8 in female with slightly bilobate hind margin extending below opening of spermathecal duct; segment 9 with small tergite fused laterally to narrow band-like sternite, sternite usually dividing in midline around spermathecal opening; segment l0 small; cercus rounded, on small dorsolateral basal plate. Segment 8 in male with normal tergite and sternite; tergite 9 usually enlarged and prolonged backward to cover other elements of terminalia; gonopod two-segmented, conspicuous; aedeagus extending back from sternite 9 and articulated laterally with base of gonocoxite, often triangular with sclerotized lateral arms or ventral plate; paired parameres usually present above aedeagus. Early stages usually found in moist or aquatic habitats; larva apneustic, often elongate in form, and a strong swimmer; head usually sclerotized; mandible strong, toothed, not apposed; pharyngeal apparatus conspicuous internally, with two strongly diverging arms and series of combs apparently serving to reduce and sort food; short collar between head and thorax; three thoracic and nine abdominal segments well-defined; no functional spiracles.
