REVISION OF COELIDIINAE 107 



& D. Q. Cavagnaro); 16 miles N.E. of K. Lumpur, 1000 ft, 1 <$, 8.vi.i962 (E. S. 

 Ross & D. Q. Cavagnaro) (CAS, San Francisco). New Caledonia: Bourail, 1 $, 

 iii. 1959 (N. L. H. Krauss) (BPBM, Honolulu). 



Biology. Unknown. Collection records indicate that this species is prevalent 

 from July to November. 



Remarks. Tharra marlatti is very similar to borneoensis on the basis of the male 

 genital characteristics, but it can be separated from the latter species by having 

 a narrower crown and smaller size. This species is named for my good friend and 

 colleague, Dr Robert B. Marlatt. 



Tharra borneoensis sp. n. 



(Text-figs 284-288) 



Length: $ o-io mm, $ unknown. 



General colour testaceous with ochraccous markings on middle of clavus and apex of elytra. 

 Crown fuscous; eyes testaceous; pronotum fuscous; scutellum fuscous anteriorly, ochraceous 

 posteriorly; elytra testaceous with a narrow ochraceous band along middle of clavus and a 

 large ochraceous spot between apex of clavus and apex of elytra; clypeus and clypellus light 

 ochraceous. 



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

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

 carinate laterally, lateral margins nearly parallel; disk elevated above eyes; ocelli small, 

 situated anteriorly; eyes moderate size, occupying nearly two-thirds of entire dorsal area of 

 head; pronotum long, median length greater than median length of crown, surface finely 

 knobbed; scutellum large, median length greater than median length of pronotum; elytra 

 long and narrow, veins obscure, appendix well developed, venation as in description of genus; 

 clypeus long, very broad anteriorly, narrowed posteriorly, without median longitudinal carina, 

 lateral margins constricted medially, surface finely granulose, rugulose along anterior margin; 

 clypellus with lateral margins broadly constricted medially. 



Male pygofer in lateral aspect with long, narrow, curved process arising from caudoventral 

 margin, process broad basally, very narrow and attenuated apically, sharply pointed apically; 

 aedeagus in lateral aspect with dorsal appendage broad at basal two-thirds, attenuated at 

 apical one-third, curved dorsad at apex; dorsal appendage with a pair of long spines situated 

 basally on lateral margin, projecting basad, ventral margin with a row of sharp spines basally; 

 ventral appendage long, somewhat tube-like, apex slightly expanded, reaching apex of dorsal 

 appendage; gonopore apical; connective Y-shaped; plate with distal appendage elongate, 

 broad apically. 



Specimens examined. 



Holotype $, Borneo: north, Mt Kinabalu, Bembangan Trail, 18.iii.-4.iv.1964 

 (S. Kueh) (BMNH, London). 



Paratypes. Borneo: north, Mt Kinabalu, Mesilau Camp, 5000 ft, 1 <$, 

 20-27. iii. 1964 (S. Kueh) (BMNH, London); 1 <£, same data as paratype, in author's 

 collection. 



Biology. Unknown. 



Remarks. Tharra borneoensis is very similar to marlatti in male genital character- 

 istics, but can be separated from the latter species by the plate with distal appendage 

 expanded apically and the style, which is hooked apically.
