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

 from May to December in the Philippines. 



Remarks. Tharra maculiceps is one of the few species of Tharra that has a 

 median longitudinal carina on the clypeus. From rufivena, its nearest relative, 

 maculiceps can be separated by the depressed, carinate crown and the pygofer with 

 apical enlarged subencapsulated pygofer process. 



Tharra knighti sp. n. 



(Text-figs 1 1 9-123) 



Length: £ 4-30-4-70 mm, 9 unknown. 



General colour piceous, sometimes with small ivory spots on elytra. Crown piceous with 

 small ochraceous area on disk between eyes; eyes luminous; pronotum and scutellum piceous; 

 elytra piceous with small ivory spots on cells; clypeus and clypelius piceous. 



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

 eyes, distal length less than one-fourth entire median length, striate radially, slightly carinate 

 laterally, lateral margins converging basally, disk depressed medially, elevated above eyes; 

 ocelli small, situated anteriorly; eyes large, bulbous laterally, occupying nearly two-thirds of 

 entire dorsal area of head; pronotum short, median length less than median length of crown; 

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

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

 anteriolateral margins slightly wider than posteriolateral margins, constricted medially with a 

 prominent median longitudinal carina reaching just below the antennal sockets, surface finely 

 granulose, rugulose along anterior margin; clypelius with lateral margins nearly parallel, 

 slightly divergent apically. 



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

 process finely striate at apical half; aedeagus simple, without spines; dorsal appendage narrowed
