Fig. 23. Mansonia africana: dorsal aspect of ter- 
minal abdominal segments of male (after Edwards, 
1941). 
abdomen and paddles in dorsal view and of the 
trumpets were given by Edwards (1941: 384). 
The latter reference is the source of the figures 
and notes included here. 
Since all the setae are simple and no other 
species of the subgenus except M. uniformis 
from New Guinea have been described, it seems 
unnecessary to attempt a complete and detailed 
description at this time. According to Edwards 
the trumpets are long, with the meatus about 
six times as long as broad. 
Mansonia (Mansonioides) uniformis 
(Theobald) 1901 
A few notes on the pupa by Edwards and 
Given (1928: 346) based on specimens from 
Singapore and without figures are scarcely of 
diagnostic value. However, Edwards (1941: 
384) included a brief note on separating this 
species from M. africana, but no figures. 
All that is known may be stated as follows: 
Abdominal segments II to VII each with four 
strong setae on the hind margin. Trumpets 
shorter than in M. africana, the terminal chitin- 
ized spine of the pinna being about one-third 
of the total length, its margin smooth; meatus 
only about four times as long as broad. 
Genus AEDOMYIA Theobald 
DIAGNOSIS. — Trumpet short, with large and 
very oblique opening; a short tracheoid area 
at base. Cephalothoracic setae mostly small and 
inconspicuous, but dorsal seta (8) and median 
metanotal seta (10) large, similar to the float- 
hair. H, K, L, and M all small and grouped close 
together; float-hair composed of simple 
branches, not dendritic, similar to seta C on 
the following segments. Seta B very long, stout, 
and dark with some small basal side branches 
on segments IV to VI. Paddles narrow at base, 
widened distally, with a long terminal seta; 
midrib dividing paddle about equally.

Fig. 24 
Pupa partially described and fully figured by 
Baisas (1938: 181) from the Philippine Islands. 
Diagnosis. — In addition to the characters of 
the genus, A. catasticta has the following fea- 
tures which distinguish it from the other species. 
Setae A on segments II— VIII present as a grad- 
uated series of stout spines resembling seta A 
in Anopheles; seta v on segment IX is present 
as a small stout spine as in the genus Culex, but 
much smaller than found in Uranotaenia. 
Discussion. — Both Baisas ( loc . cit.) and 
Edwards (1941: 372) point out that seta B is 
absent from segments II and III. Realizing that 
the setae of segment II of most culicines are 
subject to great variation in position, one might 
assume that the medium-length stout one mesad 
of C is B, but this seta conforms in size and 
form, if not position, to seta c' of the following 
segments. The only logical conclusion, there- 
fore, is that seta B-II is absent. However, on 
segment III, if seta B is really absent, there re- 
mains a small three- or four-forked seta anterior 
to and between c' and C to which no designa- 
tion will be assigned. Therefore, although this 
seta is not obviously homologous, I am tenta- 
tively designating it as B-III. 
Cephalothorax. — Postocular: 1 small, 
simple; 2 small, four-branched; 3 small, four- 
branched.
