fluent, the intervals ca. 1/2 the width of the punctures and shiny. The 
surface appears subopaque because of the dense punctures. Setae 
moderately dense, decumbent, 0.04 mm long, tactile setae suberect, 
0.04 mm. Frontoclypeal suture distinct but not deep; surface of cly- 
peus similar to frons. Labrum ogival, shiny. Last segment of maxil- 
lary palpi narrowly securiform (Fig. 5), 0.20 X 0.09 mm. Eyes 
moderately prominent, moderately coarsely faceted, 0.33 X 0.23 mm, 
separated by 0.51, a line connecting their hind margins 0.26 mm from 
middle of base. Antennae moderately slender, gradually thicker 
apically, the segments distinctly separated. Measurements in 0.01 mm : 
19/9, 9/6, 13/8, 12/8, 13/8, 10/9, 12/9, 12/9, 12/9, 12/9, 18/9. 
Segment 1 parallel-sided, feebly pedunculate, 2-10 thickest near apex, 
gradually more truncate at apex, 6-10 distinctly truncate at base, 
subtriangular ; 11 truncate at base, tapering to a blunt point from 
basal third. 
Pronotum unusually large and broad, 1.13 mm long, 0.59 wide at 
base, 0.84 at beginning of expanded portion 0.26 mm from base, 1.00 
maximum, 0.36 at the short collar. The apical area behind the collar 
is elevated above the collar, with the border of this elevated area 
slightly concave. This anterior border meets the sides in an even but 
rather sharp curve; the sides are then subparallel about half-way to 
the base, then slightly convergent to another sharp curve, which ends 
at the level of the distinct basal impressed line. Disc moderately 
flattened. Surface similar to head but punctures smaller and ca. 0.02 
mm from center to center anteriorly and laterally, almost as on head 
in posterior half of disc. Lateral margins evenly rounded, but in a 
curve that is about as sharp as the one that joins the front and side 
margins. Elytra almost parallel, 2.44 mm long, 0.95 wide at the dis- 
tinct humeri, 1.20 maximum, with the apices gently conjointly rounded 
and narrowly rounded at suture. Disc almost evenly rounded in 
transverse section ; postbasal transverse impression feebly indicated. 
Surface with lightly papillate punctures ca. 0.04 mm from center to 
center, appearing feebly shiny. Setae moderately dense, subappressed, 
0.08 mm long, tactile setae subdecumbent, slightly curved, 0.04 mm. 
Wings well-developed, probably functional. 
Mesosternum shallowly punctured and pubesecent medially, shiny 
and almost smooth laterally, the ventral portion of the mesepisterna 
similar to the sides. Mesepimera narrowly visible along edges of ven- 
tral portion of mesepisterna. Abdomen shiny, finely punctulate and 
with setae similar to elytra. Sternum 7 not modified, truncate at apex. 
Sternum 8 with a shallow transverse depression that is only very 
sparsely punctulate with a few fine setae, deepest near apex and extend-
