Biology. Unknown. 



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

 maai can be separated by the presence of a dentate ventral margin of the dorsal 

 appendage of the aedeagus, and by the long, narrow crown. 



This species is named for Dr T. C. Maa who collected much of the material treated 

 herein.

 in both sexes; pronotum deep testaceous in <$, light ochraceous in £; scutellum deep testaceous 

 in (J, ochraceous in § with three testaceous spots anteriorly; elytra ochraceous at basal two-thirds, 

 and deeply testaceous at apical one-third in g, pale ochraceous with veins deeply marked with 

 testaceous in Cj; clypeus ochraceous at apical one-third, deeply testaceous at basal two-thirds, 

 ochraceous throughout in §; clypellus deeply testaceous in £, ochraceous in $ with a longitudinal 

 testaceous band medially. 



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

 anterior margin of eyes, distal length about one-fourth entire median length, striate radially, 

 lateral margins converging basally, disk elevated above eyes; ocelli small, situated anteriorly;

 granulose at basal two-thirds, rugulose at apical one-third; clypellus with lateral margins 

 expanded apically.

 margin, process with lateral margins equidistant at basal two-thirds, broadening at apical 

 one-third, aperturized at apical one-third on inner lateral margin; aedeagus in lateral aspect 

 with dorsal appendage broad at basal two-thirds, narrowed and constricted at apical one-third, 

 tube-like and curved at apical one-third; dorsal appendage without spines or flanges; ventral 

 appendage long, narrow, tube-like, curved dorsad at apex, reaching apex of dorsal appendage;
