Diagnosis

Within the Pitambara species presenting a costal hyaline patch on the tegmina ( Fig. 1 ), P. triremiprocta is the only one for which this patch is roughly triangular, with a very large base along the costal margin and its tip reaching the level of CuA, and with an apical hyaline patch having a brown sinuate stripe inside ( Fig. 5 ).

Etymology

Free arrangement between the words “trireme” and “proctodeum” since the apex of the anal tube is shaped like the bow of ancient Mediterranean warship.

Type material

Holotype

CHINA: ♂, Menglun , Yunnan Province, 570 m, 11 Dec. 1999, coll. Daozheng Qin ( NWAFU).

Paratypes

CHINA: 1 ♀, primeval forest, Menglun, Yunnan Province, 8 Jun. 1974, collector unknown ( NWAFU); 1 ♀, Jinghong, Yunnan Province, Aug. 1975, coll. Ding Jinhua ( NAU).

Description

Length, male (including tegmina) (n = 1): 8.2 mm, female (including tegmina) (n = 2): 8.2–8.5 mm.

Vertex 1.3 times longer in midline than broad at base, anterior margin V-shaped well marked, lateral margins elevated and posterior margin largely rounded, with its most anterior point being at the level of the middle of the compound eyes ( Fig. 8 ). Frons 1.5 times longer in midline than its widest part ( Fig. 9 ), slender median carina present. Pronotum 4.1 times broader at widest part than long in midline ( Fig. 8 ). Mesonotum 1.4 times broader at widest part than long in midline ( Fig. 8 ).

Coloration

Vertex pale tawny, with three fuscous longitudinal stripes, anterior and lateral margins black ( Figs 5, 8 ). Eyes brownish ochraceous ( Fig. 8 ). Frons pale tawny, with a broad white transverse band at base, sublateral carinae ochraceous ( Fig. 9 ). Clypeus yellow, with apical part dark brown ( Fig. 9 ). Gena greyish white, with one fuscous transverse stripe crossing ocellus ( Fig. 7 ). Ocelli brown. Pronotum tawny, with median and lateral carinae yellow; the median area surrounded by lateral carinae brown ( Fig. 8 ). Mesonotum black, median carina black, lateral carinae with upper half black and lower half tawny, lateral area dark brown mixed with tawny ( Fig. 8 ). Tegmina dark brown; costal margin with several short fuscous transverse stripes near base, one very large white triangular marking at middle extending to outer margin of clavus, sparsely diffuse with short fuscous stripes inside; apical part of tegmina with two small irregular white markings along costal margin, and white at apex, with one fuscous sinuate stripe inside ( Fig. 5 ). Hindwings pale brown. Legs pale tawny, fore and middle femora and tibiae diffused with fuscous transverse stripes.

Male terminalia

In lateral view, pygofer higher than wide, with dorsal margin deeply sloping posteriorly for the first half and slightly sloping for the second half, postero-dorsal angle rounded ( Fig. 10 ); dorsal margin shorter than ventral margin; posterior margin with a deep cut out on its ¼ upper part. In ventral view, pygofer posterior margin almost straight, with the exception of lateral angles rounded ( Fig. 11 ). Anal tube in dorsal view wider than long, with apical part slightly convex and lateral margins oblique, dorso-lateral angles obviously prominent at each side ( Fig. 13 ), in lateral view anal tube prolonged posteriorly beyond the anal opening point by a medio-ventral extension gradually tapering to apex ( Fig. 10 ). Gonostylus approximately as high as broad; dorsal margin concave near middle, with a small hook-like process directed postero-ventrally; ventral margin obliquely rounded ( Figs 10, 14 ). Periandrium in lateral view rounded apically, bearing on each side a fold rounded apically as well, but bearing a series of very small teeth ( Figs 15 , 38 ). Aedeagus bearing a pair of ventral processes oriented anteriorly ( Figs 15 , 39 ); in ventral view, apex of periandrium with a clear ditch; ventral process of aedeagus zigzag shaped ( Fig. 12 ).
