Simulium View in CoL View at ENA sp. A

The arrangement of gill filaments of this species is similar to that of S. varicorne from West Malaysia ( Takaoka and Davies 1995), but the adults differ by having antennae with 11 flagellomeres. The larva has minute, dark, scalelike setae with 3–6 branches on abdominal segments IV–VIII ( Fig. 2 View FIGURE 2 E). The dorsal and middle groups of the gill, each with three filaments, share a short stalk, and the ventral group of two filaments arises from an independent stalk ( Fig. 3 View FIGURE 3 B). The larva is characterized by a deep postgenal cleft, 4.7– 7.0 times as long as the postgenal bridge ( Fig. 4 View FIGURE 4 F).

The chromosomal quality of the slide preparations for this species was poor. Two of 12 larvae were analyzed for major landmarks. The IIS arm has the bulge near the subterminal ring of Balbiani ( Fig. 1 View FIGURE 1 F).
