Amemboa (Amemboides) perlata Polhemus and Andersen 1984 View in CoL : Steenstrupia 100−103.

Diagnosis. Males of A. perlata can be distinguished from those of A. velaris by the genital segments shorter than the pregenital part of the abdomen ( Fig. 34 View FIGURES 22 – 35 ), whereas A. velaris have the genital segments as long as or longer than the pregenital part of the abdomen ( Fig. 35 View FIGURES 22 – 35 ).

Discussion. Amemboa perlata has been recorded from India, Laos, Thailand, and Vietnam ( Polhemus & Andersen 1984, Zettel et al. 2007). In Thailand, this species has been collected from Phrae, Phetchabun, and Saraburi provinces ( Polhemus & Andersen 1984, Zettel & Chen 1997). In this study, this species was collected only from rock pools in Phitsanulok Province and it did not occur synoptically with any congeners where it was collected.

Material examined. THAILAND: Phetchabun Province: Nam Nao NP, Heuy Prom Laeng, 16°38'N 101°34'E, 520 m, 9-III-2002, G.W. Courtney (1 winged female); Phitsanulok Province: Phu Hin Rongkla NP, Palad Waterfall, 17°01’N 100°56'E, 300 m, 7-V-2003, A. Vitheepradit, T. Prommi and M.L. Ferro, L-509 (1 winged female).
