Arctornis parvaclava sp.
16-17mm. The wings are much as in corrugata, though
without a discal spot. The fringes are slightly grey. The head, palps and legs
are marked as in magnaclava. The male genitalia have an uncus and valve
shape as in magnaclava, though the valves are shorter. The harpe is very
much shorter (only half as long as in magnaclava), still clublike, though
with the spining restricted to the apex of the club, which does not extend
beyond the valve margin.
Taxonomic note. It is possible that one of magnaclava, parvaclava, or possibly
the species described next, is clavigera Toxopeus. However, a specimen in
BMNH (slide 2132) stated to have been compared with the type of clavigera has
genitalia as in camurisquama Collenette (See
A camurisquama Collenette comb.n).
