Abdomen. Clad with purple-brown scales above, with spots of silvery 
scales laterally and with pale scales on the venter. Genitalia. The eighth 
segment consists of a dorsal and ventral flap which flaps partially overlap 
and conceal the ninth or genital segment. The ventral flap is fringed 
with short golden-brown stiff spines which point directly backwards. The 
ninth segment consists of a chitinous plate above a swollen globose ventral 
portion and the genital lobes between. Each genital lobe has three surfaces 
one looking inwards parallel to its fellow of the opposite side, one convex 
looking upwards and outwards and one concave looking downwards and 
outwards, on the apex ol each is a conical chitinous clasper broad at the 
base with a triangular transverse section flattened from side to side at its 
apex and barbed on the upper edge, the under edge having a double curve. 
At rest this process points ventral wards. Inserted more externally but 
still on the apex of the genital lobe is a chitinous process round in section 
at first then becoming flattened from side to side and broadening out and 
rom the lower angle of this a curved hook passes in a plane at right angle 
to the plane of the broadened-out portion. The other angle ends abruptly 
m a point. Internal to both lobes that is between the two and on the 
ventral aspect is a double curved long chitinous internal clasper pointed at 
its end and between these two, sharp, spine-like pieces project which are 
probably part of the penis. 
Occurrence. Sylvan ; caught in the jungle near Kuala Lumpur. 
. Remarks. Though this mosquito is described under a separate name 
it is quite possible it will prove to be the male of Verrallina Malayi or 
Imitator the noticeable difference being the presence of well-marked lateral 
a dominal spots in the above and their absence in Malayi and Imitator. 
As they were not taken in the same place they may be distinct.
