Suprazonal portion of aedeagus in lateral view somewhat 
bottle-necked before the slight vesical expansion; longer than 
the subzonal portion; with five conspicuous spinules on each 
side: the first (counting proximad), at about 0.05 from tip 
(thus on the level of the apex of the ventral notch), 0.008 long, 
the next, immediately beneath, 0,018 (maximum), the third 
and fourth both 0,022 (max.), likewise placed together, at 
about 0.015 proximad from second and about the same distad 
from the fifth which is subequal to the latter. Vesical opening 
plus fissure somewhat less than half the suprazonal sheath. 
Surculi forming in profile a small sharp projection about 0.025 
long. Furca about a fourth of the aedeagus, connected with the 
uneven but not actually serrated flaps of the indistinctly two- 
lobed sagum which rather loosely hangs from the zone ventrad. 
Falx with a thick blunt forearm and a high shoulder about half 
the forearm in height. Valve slightly shorter than the aedeagus, 
about twice as long as broad, resembling a Chilades valve in 
miniature but with a somewhat sharper mentum. Rostellum 
more or less distinctly angled about half-way down, with a 
plain, in some specimens slightly upturned tip (as in Chilades 
galba) descending in front of the mentum. 
Female: ventral piece of fibula 0.13 long by 0.2 broad. Pa- 
pillae anales 0.35 by 0.3. Rods 0.75. 
Measurements (in mm.): aedeagus 0. 8-1.0, suprazonal por- 
tion 0.51-0.56 (mean 0.54), subzonal portion 0.30-0.44 (mean 
0.40) with mean breadth 0.09 (in lateral view) ; penis mean 
0.80; furca mean 0.24; sagum mean 0.3. Vertical/Horizontal 
extension of uncus: forearm 0.23/0.045-0.3/0.06 (mean 
0.27/0.05), humerulus mean 0.075/0.15, shoulder mean 
0. 1 5/0.09, lobe 0.2 7/0.05 = 0.33/0.07 (mean 0.30/0.06 ) . Valve : 
0.65-0.80 (mean 0.74) with breadth 0.25-0.47 (mean 0.33).
