Notes on variation:
This species can be identified based on the following characters 1. Base of anal collar hook slender; dorsal denticle short, slender 2. Aedeagus with well developed dorsal apodeme, lamellate process of aedeagus broad. Specimens studied in the present work agree well with
A. sinuata
except the aedeagus dorsal lamellate process (
Fig. 45
) is lacking, the position of gonopore is different and the apex of the aedeagus is acute and produced.. These can be considered as extremes of intraspecific variation. The female seventh sternite (
Fig. 19
) hind margin is concave medially. Valvulae I (
Figs. 20–21
) have more than ½ of the dorsal sculptured area with elliptical scales. Valvulae II (
Figs. 22–23
), in lateral view, have the dorsal margin concave in the middle and convex apically on the toothed areas, with many small blunt teeth.. Photographic illustrations of male and female genitalia and description provided here will broaden the species concept. The possibility that such extreme intraspecific variation represents an evolutionary trend needs further exploration.
