REVISION OF COELID1INAE 61 



veins semiprominent, appendix well developed, venation as in description of genus; clypeus 

 long, slightly broader anteriorly than posteriorly, constricted near antennal sockets, remnants 

 of median longitudinal carina present, surface finely granulose, anterior margin rugulose; 

 clypellus with lateral margins parallel. 



Male pygofer in lateral aspect with long, curved process arising from near caudodorsal 

 margin, process with small, short, secondary spine subbasally; aedeagus in lateral aspect with a 

 pair of very long, distinct spmes on dorsal margin of dorsal appendage, situated basad of 

 apex; dorsal appendage very broad throughout, apex subquadrate; ventral appendage tubelike, 

 apex reaching apex of dorsal appendage; gonopore apical; connective Y-shaped; style not 

 clawed apically, slightly curved. 



Specimen examined. 



Holotype <$, New Guinea: W. Highlands, Goiburung, E. of Korn Farm, 

 1560-1650111, 16. x. 1968 (/. L. Gressitt) (BPBM, Honolulu). 



Biology. Unknown. 



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

 biclades can be distinguished by the presence of a subapical spine on pygofer process. 



Tharra bicornipes sp. n. 



(Text-figs 144-148) 



Length: <§ 5-15 mm, $ unknown. 



General colour piceous. Crown fuscous; eyes light brown; pronotum, scutellum and elytra 

 piceous; clypeus and clypellus piceous. 



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

 margin of eyes, distal length about one-third entire median length, striate radially, slightly 

 carinate laterally, depressed slightly medially, lateral margins nearly parallel, disk elevated 

 above eyes; ocelli small, situated anteriolaterally; eyes large, semiglobular, occupying over 

 one-half entire dorsal area of head; pronotum short, median length less than median length of 

 crown, surface minutely knobbed; scutellum medium size, median length only slightly longer 

 than median length of pronotum; elytra elongate, veins prominent, venation as in generic 

 description, appendix well developed; clypeus broad anteriorly, narrowed posteriorly, without 

 median longitudinal carina, surface finely granulose, rugulose on anterior margin, clypellus 

 with lateral margins broadly divergent apically. 



Male pygofer in lateral aspect with long curved process arising caudoventrally, process with 

 short, stubby subbasal spine and aperturized on inner lateral margin at apical half; aedeagus 

 in lateral aspect with dorsal appendage with numerous minute spines subasally on dorsal 

 margin, two pairs of long spines and a large lateral flange on each side, one pair of long spines 

 arising subapically on dorsal margin and projecting anteriorly, a subbasal pair arising laterally 

 and projecting anteriorly, flange triangulate on each side in dorsal view with short lateral 

 projection; dorsal appendage broad throughout; ventral appendage narrow, tube-like, reaching 

 apex of dorsal appendage; gonopore apical; connective Y-shape; style clawed apically; plate 

 with distal segment elongate, broadly lanceolate.
