Ptycta

Ptycta polluta, photographed by Graham Montgomery.


Belongs within: Psocinae.

Ptycta is a widespread genus of barklice, with a particular radiation of species on the Hawaiian islands.

Characters (from Mockford 1993): Adults of both sexes macropterous. Nine distal inner labral sensilla. Forewing markings extremely variable: usually a dark mark in pterostigma and dark marks on diagonal from pterostigma base to nodulus, but some species with extensive wing banding. Hypandrium with or without basal sclerites; with asymmetrical median strap based in middle or right, some species with processes at base of strap. Phallosome slightly tapering and rounded anteriorly; distally with pair of semi-membranous (presumed) external parameres and median aedeagal process of varying width, usually bifid at apex. Mape epiproct chair-shaped, extending anteriorly over clunium. Male paraproct with distal process long, slender, acuminate; no bulge on shoulder lateral to process; sense cushion near base of paraproct; basal articular region short and broad. Subgenital plate with distal piece short and wide, about as long as its basal width; pigmented arms directed anterolaterally, somewhat widened distally. Ovipositor valvulae: v2 with long, slender distal process; v3 ovoid; median lobe variable—prominent to absent.
