[September -December 
Diagnosis. The large size, the third antennal segment which is 
i.'5 times or more the length of the second segment, and the shape 
of the aedeagus serve to distinguish this species. 
Redescription. Measurement of lectotype: HW, 0.85. PW, 1.63. 
PL, 1.23. EW, 1.63. EL, 2.74. 
Length 4. 1-4.7 mm. Width 1.66-1.73 mm. Color uniform dark 
reddish-brown, shining. Shape oblong, moderately elongate, not very 
convex. 
Head without trace of eyes; sparsely punctate. Antennae well 
supplied with long hairs throughout length, last three segments with 
dense vestiture; segment III 1.5 X or more the length of II; III 
slightly wider than II; IV, V, VI as wide as II, subglobose, slightly 
longer than wide; VII, IX, X cup shaped; VII longer than but nar- 
rower than IX and X; VIII shorter than but slightly wider than 
VI ; XI conical. 
Pronotum widest at middle, sides evenly arcuate; narrower at 
front than back ; hind angles rectangular ; front angles rounded ; 
front margin evenly emarginate to receive head; hind margin weakly 
convex ; disc finely but not closely punctate ; covered with fine strigae. 
Elytra fused ; at base slightly wider than base of pronotum ; widest 
at middle; sides slightly arcuate; narrowing in apical third; each 
with seven striae of close punctures, less distinct at sides and apex, 
intervals flat, sparsely punctate. 
Protibia gradually widening to apex; setose on apical half of inner 
margin. Mesotibia gradually widening to apex; sharply outward 
flaring in outer margin at apex; spinose on outer concave margin; 
inner margin sinuous; setose on apical half of inner margin. Meta- 
tibia gradually widening to apex; inner and outer margin slightly 
sinuous; setae on apical half of inner margin. Penultimate abdominal 
segment, 'fourth, with transverse depression on either side. 
Male protarsomeres not dilated. Abdominal segment five truncate. 
Aedeagus poorly sclerotized ; thin and straight in lateral view ; wide 
and straight in dorsal view; tip dorsoventrally flattened, slightly up- 
turned at edge, smoothly rounded in dorsal view, 14 setae along 
edge; parameres separated, longest on ventral surface but not reach- 
ing tip of aedeagus, partially covering anterior ventral surface and 
dorsal median surface of aedeagus (fig. 3). 
Female abdominal segment five rounded. 
Note on lectotype. The specimen is damaged. It possesses only 
two prothoracic and one metathoracic legs. One antenna is missing 
its terminal segments.
