Description of New Species 
Ischyropalpus tibialis, new species 
(Fig. 2) 
2.48 - 3.02 mm, dark piceous, elytra slightly paler, legs and an- 
tennae brown. Head and pronotum sparsely and finely punctured, 
not sharply margined. Pubescence in weak postbasal transverse im- 
pression of elytra not oblique or transverse. Hind tibiae of cf with 
a tuft of long setae medially near apex. 
Holotype cf : Length 2.82 mm. Head 0.49 mm long to the 
distinct frontoclypeal suture, 0.58 wide across eyes, 0.49 just behind, 
the base short and evenly rounded behind eyes, a line connecting the 
hind margins of the eyes 0.17 mm from middle. Surface smooth and 
shiny, the punctures small and 0.03 to 0.04 mm from center to center, 
the intervals not curving down to them. Disc evenly curved, not 
very convex, the clypeus on almost the same curve. Pubescence sparse 
and inconspicuous, decumbent, almost appressed, 0.06 mm long, 
slightly curved ; tactile setae erect, straight, fine, 0.08 mm. Last 
segment of maxillary palpi 0.20 mm long on outer side, 0.15 on 
inner, 0.17 across apex, the apical angles well-defined. Eyes large 
and moderately prominent, 0.26 X 0.19 mm, separated by 0.41, 
finely faceted, with curved setae ca. 0.0 1 mm long at intervals in 
posterior half. Antennae with segment 1 slightly swollen in middle 
and feebly pedunculate, segments 2-10 widest near apex and becoming 
more triangular, 11 truncate at base, widest near middle, the sides 
then curving to a blunt point. Measurements in 0.01 mm: 17/8, 
10/5, 13/5, 12/5, 12/6, 12/6, 12/6, 12/7, 12/8, 10/8, 18/8. 
Pronotum 0.64 mm long, 0.38 wide at base, 0.3 1 at the well- 
! defined constriction 0.23 111m from base, 0.54 maximum at 0.44 mm 
j from base, 0.23 at the short but well-defined collar. Basal impressed 
line distinct. Sides almost evenly rounded from constriction to collar 
| and disc evenly convex from basal impressed line to collar. Surface 
as on head, the punctures slightly deeper and sparser. Elytra 1.69 
mm long, 0.74 wide at the well-marked humeri, 0.90 maximum just 
before middle, subparallel. Omoplates feebly elevated; postbasal 
transverse impression feeble, with punctures no denser or deeper than
