General colour pale stramineous. 



Head narrower than pronotum ; crown long and narrow, produced considerably beyond 

 proximal margin of eyes, distal Length nearly two-thirds entire median length, striate longi- 

 tudinally, slightly carinate laterally, lateral margins slightly convex, disk elevated above 

 eyes; ocelli small, situated laterally; eyes moderate size, occupying less than half total dorsal 

 area of head. 



Male pygofer in lateral aspect with short proc mi; from middle of caudal margin, 



process bulbous dorsally with spine-like projection ventrally; aedeagus in lateral aspect with 

 small lateral spine on middle of dorsal appendage, projecting basally; ventral appendage 

 with subapical flange laterally and a keeled flange ventrally; gonopore apical; connective 

 Y-shaped; style with apex broadly hooked; plate elongate, terminal segment slightly bulbous 

 subapically. 



Female seventh sternum with posterior margin produced medially. 



Distribution. Misool (West Irian, Raja Ampat Is.). 



Specimens examined. 



Coelidia tiarata Stal, lectotype $, 'Mysol' [Misool] (Stevens) (NR, Stockholm); 

 paralectotype $, 'Mysol' [MisoOl] (Stevens) (NR, Stockholm). Nisitra varipes 

 Walker, holotype g, 'Mysol' [Misool] (Wallace) (BMNH, London). Nisitra 

 telifera Walker, holotype $, 'Mysol' [Misool] (Wallace) (BMNH, London). 

 Examination of these types has shown that the last two names are junior synonyms 

 of tiarata. 



Biology. Unknown. 



Remarks. Tharra tiarata is a rare and unique species, having the longest head 

 of any known species in the genus. From frontalis, to which it is similar in genitalic 

 characters, tiarata can be separated by the short pygofer process and the flanged 

 ventral appendage of the aedeagus.
