Diagnosis

Within the Pitambara species presenting a rectangular costal hyaline patch on the tegmina ( Fig. 1 ), P. tricorne sp. nov. is the only one presenting a whitish frons with two brown bands near lateral angles and sublateral brown carinae ( Fig. 31 ). The “tricorne” shape of the periandrium’s apex is unique.

Etymology

Named after a hat in fashion during the 18 th century in France, the “tricorne” was that of a triangular shape and folded in 3 horns. The apex of the periandrium has a similar shape. Name placed in apposition.

Description

Length, male (including tegmina) (n = 2): 7.8–8.1 mm.

Vertex 1.3 times longer in midline than broad at base, lateral margins elevated. Frons 1.4 times longer in midline than widest part. Pronotum 4.1 times broader at widest part than long in midline. Mesonotum 1.5 times broader at widest part than long in midline.

Coloration

Vertex greyish white, with three slender fuscous longitudinal stripes; lateral stripes with small fuscous patches at base; lateral margins black ( Fig. 30 ). Eyes grey ( Fig. 30 ). Frons white; two very small fuscous spots near apex and two fuscous bands near lateral angles; sublateral carinae brown ( Fig. 31 ). Clypeus dark brown, median area yellow ( Fig. 31 ). Gena greyish white, with one fuscous transverse stripe crossing ocellus ( Fig. 29 ). Ocelli grey. Pronotum with median area between eyes black and lateral area grey ( Fig. 30 ). Mesonotum black ( Fig. 30 ). Tegmina dark brown, costal margin with several fuscous transverse stripes at basal ¼; one sub-rectangular white marking at middle extending to median part of tegmina with two fuscous transverse stripes inside; two small irregular white markings along apical part of costal margin, and apex of tegmina white, one fuscous sinuate stripe inside ( Fig. 27 ). Hindwings pale brown. Legs pale tawny; fore and middle femora and tibiae diffused with several thick fuscous transverse stripes, hind femora dark brown and tibia yellow; lateral and apical spines black.

Male terminalia

Pygofer higher than wide in profile, with dorsal margin sloping posteriorly, posterior margin slightly concave near middle, postero-dorsal angle acute ( Fig. 32 ), posterior margin cut out from the top down to the ¾. Anal tube in dorsal view longer than wide, cylindrical, with lateral margin nearly parallel; anal opening situated at mid length ( Fig. 35 ); in lateral view with a pair of small ventral teeth hidden near apex ( Fig. 44 ). Gonostylus higher than broad; dorsal margin sinuate, with a small hook-like process directed posteriorly near base, ventral margin curved ( Figs 32, 36 ). In lateral view, dorsal margin of periandrium gently and regularly curved; apex of periandrium extremely developed and ending posteriorly into two processes and anteriorly by a process apically bifid, all processes oriented dorsally ( Figs 37 , 42 ); margin between anterior and posterior processes largely rounded. Aedeagus bearing a pair of ventro-posterior processes very long and slender, regularly curved and oriented antero-dorsally ( Figs 37 , 43 ).
