This very distinctive species has been 
adequately described by Malloch. It is 
readily separated from all known Clusiosoma 
by the peculiar process at the apex of each 
front metatarsus of the male (Fig. 21a) and 
by the characters given in the above key. 
The female ovipositor has not been described 
in the literature. A discussion of this may be 
of value here. The ovipositor is very short 
(Fig. 21 h) and peculiarly modified; the ex- 
tended length is about 2.5 mm. The piercer 
is about 0.66 mm. long by 0.19 rnm. wide. 
It is very blunt at the apex and possesses a 
pair of large conspicuous spines which arise 
just before the tip (Fig. 27c); these spines 
are about 0.09 mm. in length. A series of 
short bristles occur on each side just behind
