Plecia zamboanga Hardy, 1950, Hawaii. Ent. 
Soc. Proc. 14: 84-85, figs. 9a, b. 
A large species fitting in the fulvicollis com- 
plex because of the entirely opaque yellow to 
orange thorax. It is closest to P. fulvicollis 
(Fabricius) and is differentiated by the striking 
differences in the development of the ninth 
sternum of the male. The claspers are tiny and 
inconspicuous and are partially fused with the 
sternum. The broad, heavily sclerotized, me- 
dian process on the hind margin of the ster- 
num is truncate at apex, rather than being 
bilobed and the lobes of the posterior lateral 
margins are very differently developed (as 
shown in loc. cit ., fig. 9b). The ninth tergum 
is deeply cleft on the hind margin, the lobes 
are broadly rounded at apices {loc. cit., fig. 9a) . 
Length: Body, 9-0-9- 5 mm.; wings, 10.0- 
10.5 mm. 
type locality: Zamboanga, Mindanao, 
Philippine Islands. 
Type in the Museum of Comparative 
Zoology.
