Biology. Unknown. 



Remarks. This species is similar to crenulata in the male plate and aedeagus 

 but can be separated from that species by a very distinctive pygofer process which 

 is slightly expanded subapically and has a finger-like lobe apically.

 Tharra flavomaculata Metcalf, 1950 : 73. 



T. flavomaculata is a highly variable species, both in colour and size. Sexual 

 dimorphism is apparent among four of the five known subspecies. The females 

 are decidely more marked than the males. The male and female genital characters 

 are identical among all subspecies. Separation of the various forms is based on 

 geographical distribution (primarily Caroline Islands, Micronesia) and colour of 

 the elytra. These forms can be separated from the closely related species robust a 

 by the presence of the very short ventral appendage of the aedeagus. 



T. flavomaculata flavomaculata occurs in the eastern part of the Caroline Islands, 

 primarily on Truk Island. T. f. superba is restiicted to the far eastern area of 

 the Carolines on Kusaie Island, whereas T. f. palauensis is on the Palau Islands 

 in the far western end of the Island chain. T. f. yapicola is known from Yap 

 Island on the eastern end of the Caroline Islands and Guam, which is just north- 

 east of Yap on the southern end of the Mariana Islands. T. f. ponapensis is 

 restricted to Ponape Island near the eastern end of the Caroline Islands.
