PIPPAX EMELJANOV, 2008

Pippax Emeljanov, 2008: 307 ; Emeljanov 2011b: 1124.

Type species

Pippax opilionoides Emeljanov, 2008 ; by original designation.

Diagnosis

The genus can be distinguished from Arjuna by the following combination of characters: vertex with lateral carinae abruptly incurved before eyes and narrowed into half as wide, parallel forwards, then distinctly widened at subapex, angularly convex at apex; frons with intermediate carinae strongly ridged, nearly parallel and extending below antennae; median carina almost absent, only poorly marked below antennae.

Diversity and distribution

Pippax was erected by Emeljanov (2008) based on four new species: Pippax alboruber , Pippax bulbinaso , Pippax opilionoides , and Pippax vanstallei from Papua New Guinea.

Remarks

Emeljanov (2008) provided a key to the species of the genus. We here provide a first description of the male and female genitalia of P. opilionoides .

( FIGS 19A–E , 20A–D , 21A–F )

Pippax opilionoides Emeljanov, 2008: 309 , figs 30, 31, 33–35.

Redescription

BL, ♂ 5.8–6.5 mm , ♀ 6.6 mm; HL , ♂ 1.5–1.7 mm, ♀ 1.7 mm; HW , ♂ 0.8–0.9 mm, ♀ 0.9 mm; TL , ♂ 3.8– 4.1 mm, ♀ 4.1 mm.

Male genitalia with pygofer distinctly narrow and elongate, more than twice ventral width, distinctly wider ventrally than dorsally (∼3.0: 1.0), posterior margin more or less projecting near upper middle in lateral view ( Fig. 20B ). Gonostyles ( Fig. 20C ) symmetrical; base narrow, expanded towards middle, then gradually narrowed towards apex; in lateral view apex bluntly rounded and projecting backwards; upper process elongate, obtuse, and compressed dorsoventrally ( Fig. 20D ). Aedeagus ( Fig. 21A, B ) with a pair of slender and mod- erately long endosomal processes extended from phallotheca: pigmented, sclerotized, nearly straight, and obtuse apically; phallobase sclerotized and pigmented at base and laterally, the remainder membranous, without spines; dorsal area with a large and elongate lobe, acute apically, and directed dorsally; ventrolateral area with two narrow and elongate lobes, directed posteriorly. Segment X in dorsal view oval, with ratio of length to width at base ∼1.2: 1.0 ( Fig. 20A ). Anal style elongate, beyond the apical ventral margin of segment X.

Female genitalia ( Fig. 21C–F ) similar to Arjuna .
