Diagnosis
Within the Pitambara species presenting a rectangular costal hyaline patch on the tegmina ( Fig. 1 View Figs 1–4 ), 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 View Figs 27–37 ). 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.

Coloration
Vertex greyish white, with three slender fuscous longitudinal stripes; lateral stripes with small fuscous patches at base; lateral margins black ( Fig. 30 View Figs 27–37 ). Eyes grey ( Fig. 30 View Figs 27–37 ). Frons white; two very small fuscous spots near apex and two fuscous bands near lateral angles; sublateral carinae brown ( Fig. 31 View Figs 27–37 ). Clypeus dark brown, median area yellow ( Fig. 31 View Figs 27–37 ). Gena greyish white, with one fuscous transverse stripe crossing ocellus ( Fig. 29 View Figs 27–37 ). Ocelli grey. Pronotum with median area between eyes black and lateral area grey ( Fig. 30 View Figs 27–37 ). Mesonotum black ( Fig. 30 View Figs 27–37 ). 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 View Figs 27–37 ). 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 View Figs 27–37 ), 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 View Figs 27–37 ); in lateral view with a pair of small ventral teeth hidden near apex ( Fig. 44 View Figs 38–44 ). Gonostylus higher than broad; dorsal margin sinuate, with a small hook-like process directed posteriorly near base, ventral margin curved ( Figs 32, 36 View Figs 27–37 ). 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 View Figs 27–37 , 42 View Figs 38–44 ); 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 View Figs 27–37 , 43 View Figs 38–44 ).
