Fig. 14. Plecia fumidula diversa n. subsp. a, Ninth 
sternum; b , ninth tergum. 
the antennae are 11-segmented, with the last 
two closely joined and the basal segments are 
brownish yellow. The propleura are orange 
colored in the female, brown to black in the 
male. The halteres and legs are black, with a 
yellow tinge in the ground color of the femora 
in the female. Tibiae or tarsal segments not 
swollen. Wings brown fumose, darker in the 
male. Vein R 2+3 slightly curved in the male 
and straight in the female, entering the costa 
at about a 65° angle to R4+5. The lobes on 
posterior lateral margins of the ninth sternum 
of the male are slender, sharply pointed, and 
slightly curved inwardly. A narrow submedian 
lobe is present on the sternum just inside each 
clasper and the median portion is raised into a 
small mound. The claspers are small, rounded 
at apex, produced into a sharp, beaklike sub- 
apical point on inner side and with a rather 
broad lateral expansion on outer side (Fig. 
14 a). The posterior median third to two-fifths 
of the sternum is membranous. The ninth 
tergum is deeply cleft, the lobes are subacute 
at apices (Fig. 14 b). 
Length of male: Body, 4.8 mm.; wings, 
3.5 mm. 
Length of female: Body, 3.5 mm.; wings, 
4.8 mm.

Plecia furva Hardy 
Plecia furva Hardy, 1952, Beitr. z. Ent. 2: 429. 
An all dark colored species related to P. 
fumidula Edwards, it fits the original descrip- 
tion in all details except that the claspers of 
fumidula were described as "small and 
rounded.” P. furva is differentiated from fu- 
midula by the more elongate ninth tergum, 
the lobes extending beyond the apices of the 
sternum. The lobes of the ninth sternum are 
much broader at their bases and are gently 
tapered to a sharp point at their apices; the 
cleft on the hind margin extends about two- 
thirds the length of the sternum, rather than 
less than half the length. The claspers are also 
much more developed in furva , they are 
strongly curved with a capitate, rounded, 
apical lobe and with the basal portion slightly 
hollowed out and expanded laterally; no lobe 
present on inner margin (refer to complete 
description op. cit.: 429-431, fig. 3a, b). 
Length: Body and wings, 5.5 mm. 
type locality: Segare Anak, Lombok, 
Lesser Sunda Islands.

Institut, Berlin.
