Biology. Unknown. Collection records indicate that the species is common 

 from May to December. It apparently is restricted to Queensland, Australia. 



Remarks. This species is one of a few in Tharra that occurs only in Australia. 

 It can be separated from Australian species by the presence of two pairs of flanges 

 on the dorsal appendage of the aedeagus, and a very narrow, sharply pointed 

 pygofer process. 



Tharra kraussi sp. n. 



(Text-figs 189-193) 



Length: <J 4-10— 4-70 mm, § 5*30— 5-50 mm. 



General colour testaceous in <§, fuscous in $. Crown ochraceous; eyes light fuscous to deep 

 fuscous; pronotum fuscous to testaceous; scutellum testaceous; elytra testaceous to light 

 fuscous, sometimes with ochraceous area distad of clavus in <-£, admixture of fuscous and 

 testaceous in 9. clypeus and clypellus ochraceous to light fuscous. 



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

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

 margins strongly convergent basally, disk elevated above eyes; ocelli small, situated 

 anteriorly; eyes large, semi-bulbous, occupying nearly two-thirds entire dorsal area of head; 

 pronotum short, median length equal to median length of crown, surface finely knobbed; 

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

 elongate, veins prominent, appendix well developed, venation as in description of genus; 

 clypeus long, without median longitudinal carina, anterior margin broad, posterior margin 

 narrowed, surface finely granulose, broadly rugulose along anterior margin; clypellus with 

 lateral margins slightly concave. 



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

 process with lateral margins nearly equidistant, sharply pointed apically; aedeagus in lateral 

 aspect simple; dorsal appendage broad, narrowly constricted subapically, lateral flange on 

 each side of middle; ventral appendage long, narrow, tube-like, apex basad of apex of dorsal 

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

 segment elongate, lateral margins slightly expanded at distal half. 



Female seventh sternum with posterior margin produced medially.

Biology. Unknown. 



Remarks. This species is similar in general habitus to nakatai, but can be 

 separated from that species by the very long slender plate and the lateral flange 

 on the dorsal appendage of the aedeagus.
