Description
Male
Bolton (1998) - P. andamanensis is closely related to oculata, the two sharing the same form of depressed rectangular head capsule (fig. 8), characteristic overall shape of petiole and postpetiole (figs 16, 17), and alitrunk structure. The two differ in the following respects. In andamanensis the middle and hind tibiae lack projecting hairs, whereas in oculata long fine tapering projecting hairs are conspicuous. In andamanensis the fifth gastral tergite is broadly triangular, enlarged and shield-like, and conceals the elongate genital parameres from dorsal view. Conversely, in oculata the fifth gastral tergite is a narrow transverse sclerite and the elongate parameres project freely from the gastral apex. The propodeal declivity is more nearly vertical in andamanensis and the dorsum and declivity round together through a narrower curve than in oculata, where the declivity is not so steeply sloped (figs 16, 17). With the alitrunk in profile the propodeal spiracle is closer to the margin of the declivity in oculata than in andamanensis, and comparison of figs 16 and 17 will show the differences in shape and relative dimensions of the petiole and postpetiole.
