Harveycapsus gen. nov.

Etymology. This genus is named after the eminent Western Australian Museum arachnologist, Dr Mark Harvey, who discovered this new taxon.

Type species. Harveycapsus dimorpha Cassis, Symonds and Tatarnic, by original designation.

Diagnosis. Harveycapsus is recognised by the following combination of characters: male macropterous (Fig. 1 a); female staphylinoid (Fig. 1 b); genae elongate, head conelike (Figs 1 a & b); female head strongly vertical (Fig. 1 b); female eyes substylate (Fig. 1 b); male pygophore greatly enlarged; right paramere clubshaped (Fig. 2 b); left paramere L-shaped (Fig. 2 c); aedeagus with three elongate, serrate endosomal spicules (Fig. 2 f); female opening of vestibulum symmetrical, sclerotised (Fig. 3 a); and, posterior wall with apically serrate inter-ramal lobes (Fig. 3 b).

Description. Male macropterous (Fig. 1 a); female staphylinoid (Fig. 1 b).

STRUCTURE. Male. Head: short, transverse, strongly projected anteroventrally; clypeus rounded; genae elongate; head conelike; frons convex; eyes large, reniform, contiguous with the anterior margin of pronotum, extending beyond the anterolateral angles of pronotum to bucculae; bucculae arcuate, reaching midpoint of gula. Antennae: antennifers subcontiguous with anteroventral margin of eyes; AI elongate, subequal to interocular distance, cylindrical; AII cylindrical, elongate, longer than posterior width of pronotum; AIII little shorter than AII; AIV subequal in length to AI. Pronotum: subtrapezoidal, short, strongly transverse; lateral angles moderately divergent, ca. 45˚; callosite region weakly demarcated, shallowly depressed along midline; weak thin flat collar; calli oval, weakly concave above remainder of callosite region; posterior margin rectilinear. Mesoscutum: barely visible. Scutellum: weakly convex. Thoracic pleura: metathoracic spiracle visible, bounded by evaporative bodies; metathoracic gland moderately developed, peritreme linear. Hemelytra: elongate, parallel-sided, extending well beyond pygophore; pygophore terminating at apex of cuneus; clavus weakly convex, with a weak longitudinal fold; median flexion line short, ca. 1/3rd length of corium; cuneus moderately elongate; two membrane cells, minor cell moderately large, apex of vein evenly rounded. Legs: femora fusiform; tibiae cylindrical; tarsi elongate; pretarsal pulvilli absent. Male genitalia: pygophore greatly enlarged, genital opening dorsocaudal, cuplike sclerite extending caudad beyond ventral margin of pygophore, without tergal processes (Fig. 2 a); parameres asymmetrical, right paramere club-shaped (Fig. 2 b), left paramere L-shaped (Fig. 2 c); phallotheca simple, dorsally open near base, margins medially contiguous more distally, slitlike and oriented to right hand side (Figs 2 d & e); aedeagus with three elongate, moderately serrate endosomal spicules (Fig. 2 f).

Female. Staphylinoid, forewing greatly shortened, strongly sclerotised, tegminalike; hindwings absent. Head: short, transverse, strongly projected anterolaterally; clypeus rounded; genae greatly expanded; vertex concave, midline sulcate; eyes substylate, small, extending well beyond anterolateral angles of pronotum. Female genitalia: dorsal and ventral labiate plates without denticulate texture, sclerotized rings thin, incomplete, weakly twisted (Fig. 3 a); opening of vestibulum sclerotized, symmetrical and apparently incomplete medially (Fig. 3 a); inter-ramal sclerite broadly denticulate (Fig. 3 b); medial process of inter-ramal sclerite partially developed (Fig. 3 b); inter-ramal lobes present, short, narrow, with apices serrate (Fig. 3 b).
