Hymenaphorura subtenuis (Folsom, 1917)
Onychiurus subtenuis Folsom, 1917
Figs. 32-36

These figures are drawn from a specimen labelled cotype USNM No. 20764.

Notes: The arrangement of the setae of Abd VI, on my interpretation, differs slightly from that of Folsom. The claw is slightly granulated basally and the whip-like extension of the unguiculus is relatively shorter, the unguiculus being more lance-like.
