E t y m o l o g y: This remarkable species is dedicated to Johannes Frisch, who collected the
holotype
.
D e s c r i p t i o n: Body length
2.5 mm
; length of forebody
1.05 mm
. Habitus as in
Fig. 1
. Coloration: body yellowish-red with dark-yellow legs and antennae.
Head (
Figs 2-3
) weakly oblong; punctation very fine and rather dense, barely visible in the pronounced microreticulation. Eyes completely reduced, not even rudiments visible (
Fig. 3
). Antenna
0.6 mm
long; antennomere III of conical shape and weakly oblong; antennomeres IV-X strongly transverse, more than twice as broad as long, and of gradually increasing width, XI slightly longer than the combined length of IX and X.
Pronotum (
Fig. 2
) very weakly transverse, only 1.05 times as brad as long and 1.05 times as broad as head, with weakly marked posterior angles; punctation dense and extremely fine, nearly invisible in the pronounced microreticulation even at high magnification.
Elytra (
Fig. 2
) short and slender, as broad as, and 0.7 times as long as pronotum; punctation dense and fine, but more distinct than that of head and pronotum; interstices with shallow microsculpture and glossy. Hind wings completely reduced.
Abdomen 1.1 times as broad as elytra at segment VI; punctation fine and moderately dense; interstices with microsculpture; posterior margin of tergite VII without palisade fringe; posterior margin of tergite VIII truncate (
Fig. 5
).

); forebody in dorsal view (
