Raphignathoidea

Dorsal view of Molothrognathus leptostylus (cuticle texture shown on left side only), from Summers & Schlinger (1955).


Belongs within: Raphignathina.
Contains: Neophyllobius, Eustigmaeus, Stigmaeus, Agistemus.

The Raphignathoidea are a group of often predatory mites, many species of which are found in dry habitats. Members of the group vary from heavily armoured taxa such as the Homocaligidae and Cryptognathidae to almost completely non-sclerotised taxa such as Barbutia and the Caligonellidae. Most raphignathoids lack tenent hairs on the leg claws (albeit possessing them on the associated empodia), but the claws are haired in the soil- and litter-dwelling Barbutiidae. Members of the Cryptognathidae have the dorsal shield produced anteriorly into a distinct collar into which the gnathosoma may be withdrawn (Walter et al. 2009).

Characters (from Walter et al. 2009): Soft-bodied or well-sclerotised, with a holonotal shield or a series of smaller weakly tanned, reticulate or dimpled dorsal sclerites, rarely without shields; idiosomatic neotrichy present in some families; trichobothria absent; prodorsum usually with 3-4 pairs of setae (si may be absent), rarely neotrichous; 0-2 pairs of ocelli, second pair (postocular organ) sometimes stalked. Cheliceral bases usually swollen, free, adnate, partially fused, or amalgamated into a stylophore, each with a styliform movable digit encased in the sheathlike remnant of the fixed digit; chelicerae not fused to underlying rostral elements, retractile in Cryptognathidae. Palpi with five free segments, palptibial claw (thumb-claw process) usually present but often weakly developed or obsolete, occasionally absent. Stigmatic openings present at base of chelicerae or absent; peritremes absent or simple to highly convoluted on cheliceral bases, or located on anterior margin of prodorsum and distally emergent (Raphignathidae). Empodial elements of tarsi commonly with tenent hairs, claws usually present on all legs (replaced by padlike structures in some Stigmaeidae), tenent hairs lacking on claws except in Barbutiidae. Males with an aedeagus, genital opening typically terminal, rarely dorsal; typically with solenidia on all tarsi. Generally with four active postembryonic instars: larva, protonymph, deutonymph and adult (tritonymph present in Xenocaligonellidae).
