Remarks

Capsaloides nairagi View in CoL is most easily distinguished from other species in the genus by a zig­zagged row (see fig. 22 of Yamaguti 1968) of closely­spaced dorsomarginal body sclerites ( Fig. 2 View FIGURE 2 E) which extend to the posterior end of the body. In the holotype, the left isolated group of anterior dorsomarginal body sclerites comprises 6 sclerites each with 7– 10 cusps. The right isolated group of anterior dorsomarginal body sclerties comprises 10 sclerites, each with 3–6 cusps. The haptoral accessory sclerites ( Fig. 1 View FIGURE 1 E) are large with an elongate shaft. According to Yamaguti (1968), the egg is rhomboidal with an appendage at one end.
