to which it is similar in genitalic characters, rufivena can be distinguished by the 

 short, sclerotized, curved pygofer process with a secondary, long filamentous process 

 arising subbasally. 



Tharra papuaensis sp. n. 



(Text-figs 1 06-1 1 o) 



Length: £ 4-90— 5-30 mm, $ unknown. 



General colour fuscous to piceous with veins piceous. Crown testaceous; eyes rufous; 

 pronotum and scutellum piceous, elytra piceous with scattered ochreous spots and apex with 

 broad ochreous band; clypeus and clypellus piceous. 



Head narrower than pronotum ; crown as in rufivena except lateral margins slightly convergent 

 basally, disk without depressed areas, elevated above eyes; ocelli small, situated on anterior 

 margin of crown; eyes large, globular, occupying about two-thirds total dorsal area of head; 

 pronotum long, median length greater than median length of crown, surface covered with 

 minute knobs ; scutellum large, median length greater than median length of pronotum ; elytra 

 elongate-ovoid, veins prominent, venation as in generic description; clypeus and clypellus 

 as in rufivena, with prominent, nearly complete median longitudinal carina on clypeus. 



Male pygofer in lateral aspect with long process, process with a large secondary subbasal 

 process and several sharp spine-like processes on apical half of anterior margin; aedeagus 

 in lateral aspect with row of teeth on ventral margin of dorsal appendage; dorsal appendage 

 attenuated abruptly subapically, curved caudodorsally apically; ventral appendage tube-like, 

 apex reaching apex of dorsal appendage; gonopore terminal; connective Y-shape; style as in 

 rufivena; plate with terminal segment elongate. 



Specimens examined. 



Holotype <$, New Guinea: Papua, Mt Rui, Sudest I., 250-350 m, No. 10, 

 5.1X.1956 (L. J. Brass) (AMNH, New York). 



Paratypes. New Guinea: i $, same data as holotype (AMNH, New York); 

 1 £, same data as holotype, in author's collection. 



Biology. Unknown. 



Remarks. This species is identical to rufivena in many aspects of the general 

 habitus but can be separated by the long pygofer process with subbasal secondary 

 process and several sharp spine-like processes distally.
