Simulium weji Takaoka, 2001 View in CoL

Simulium weji differs from other species in the Thai tuberosum group by having pupae with microtubercles on the antennal sheath, conical cephalic microtubercles ( Fig. 4 View FIGURE 4 D), gill filaments decreasing in length from dorsal to ventral, the dorsal filament thicker than the others, and the upper pair on a short stalk but the middle and lower pairs almost sessile ( Fig. 7 View FIGURE 7 G). In the female, sternite VII has a pair of long clusters of hairs. In the male, the median sclerite is somewhat teardrop shaped ( Fig. 9 View FIGURE 9 E) and the head is slightly wider than the thorax. Meristic characters of the larvae (e.g., number of primary fan rays, lobules on the rectal papilla, hooklet rows, and hooklets per row) are greater than those of all other Thai members of the S. tuberosum group (Table 2) and might be related to the unique calcareous stream habitat of S. weji . The cocoons of this species accumulate a deposit of calcium carbonate.
