Biology. Unknown. Collections were made from February through August. 



Remarks. This is a unique species having a large subapical flange on the dorsal 

 margin of the dorsal appendage and a pair of long spines at the base of the stem 

 of the aedeagus just basad of the origin of the ventral appendage, which distinguishes 

 leucomelana from all other species of Tharra. 



Tharra pustula sp. n. 



(Text-figs 299-303) 



Length: $ 4*4° nam, Cj unknown. 



General colour deep testaceous. Crown testaceous, eyes deeply fuscous; pronotum and 

 scutellum deeply testaceous; elytra deeply testaceous with a few obscure, pale spots in cells, 

 apex with very narrow ochraceous band; clypeus and clypellus deeply testaceous. 



Head narrower than pronotum; crown long, very narrow basally, produced distally beyond 

 anterior margin of eyes, distal length nearly one-third entire median length, striate radially, 

 lateral margins slightly carinate, converging basally, disk slightly elevated above level of eyes; 

 ocelli small, situated anteriorly; eyes large, occupying about two-thirds entire dorsal surface of 

 head ; pronotum short, median length less than median length of crown, surface finely knobbed ; 

 scutellum moderate size, median length about equal to median length of pronotum; elytra 

 elongate, veins somewhat obscured, appendix well developed, venation as in description of 

 genus; clypeus elongate, lateral margins nearly parallel, constricted near antennal sockets, 

 remnants of a median longitudinal carina extending anteriorly to near middle, surface finely 

 granulose, anterior margin narrowly rugulose; clypellus with lateral margins nearly parallel. 



Male pygofer in lateral aspect with large, curved process arising from caudoventral margin, 

 process constricted medially, broad basally, very broad at subapical half, aperturized on inner 

 lateral margin at apical half and somewhat striate obtusely at apical half; aedeagus in lateral 

 aspect with dorsal appendage constricted subapically, apical one-third elongate, somewhat 

 expanded and curved dorsad; dorsal appendage with a pair of long, basal spines on lateral 

 margin, spines sharply curved apically and directed distad, ventral margin of dorsal appendage 

 with prominent ventral flange and a short flange on dorsal margin basad of apex, flanges 

 serrate on outer margin; ventral appendage very long, narrow, tube-like, apex reaching apex 

 of dorsal appendage; gonopore apical; connective Y-shaped; style clawed apically; plate with 

 distal appendage elongate, somewhat globular at apical half. 



Specimens examined. 



Holotype <$, New Guinea: E. Highlands, Purosa, 1700 m, 17-25. v. 1966 (Gressitt 

 6- Tawi) (BPBM, Honolulu). 



Biology. Unknown. 



Remarks. From leucomelana, to which it is similar in male genital characteristics, 

 pustula can be separated by the presence of the long, lateral spines on the ventral 

 margin of the dorsal appendage and the ventral subapical flange.
