Tento druh, který jsem pojmenoval ke cti jeho objevitele, 
jest od obou posud známých druhů velmi rozdílný a lze jej po 
přívěscích pohlavních velmi snadno rozeznati. Jest však zvláště 
zajímav tím, že spojuje rody Drusus a Ecclisopleryx, mezi kte- 
rými tvoří přechod. Při povrchním ohledání mohli bychom 
snadno býti svedeni pokládati jej za Drusus, leč ostruhy, bíle 
tečkovaná blána křídlová, i tvar VIII. obloučku hřbetního a šu- 
piny nadřitní označují jej jako Ecclisopteryx. Tvar genitálních 
noh jest sice jak u rodu Drusus, ale jejich drsný povrch opět 
poučuje nás o pravém místě v soustavě.

Spurformula 1, 2, 9. 
In the S is the VIII. dorsal segment strongly produced in 
a semicircular manner on the hind margin and scabrous by short, 
strong black spines; this prolongation is on its base lowered 
suddenly and often inasmuch retracted as to become guite invi- 
sible from above. IX. segment is thoroughly divided on its dorsal 
side and deeply excised ventrally; the side-pieces are densely 
and finely corrugated on their lower halves. Gonopods stout, 
subtr angular at the base, deeply excavated externally before the 
apex, nearly rhomboidal in the lateral view and excised on 
their upper edge; they are coarsely corrugated on the external 
surface, roughened by dense black tubercules on inner surface 
and clothed with long and dense hairs externally at the base. 
Appendices praeanales large, rhomboidal, rounded at the angles 
and strongly hairy. Supraanal sguama forming a gothic arche 
with fine fringes on the superior margin, but with stronger ones 
on the sharply produced inferior angles. Penis slender, tubular, 
with two spiniform titillators, which are furnished with a short 
Spine at their base.
