Diagnosis. Males of A. velaris can be distinguished from those of A. perlata by the genital segments as long as or longer than the pregenital part of the abdomen ( Fig. 35 View FIGURES 22 – 35 ), whereas A. perlata have the genital segments shorter than the pregenital part of the abdomen ( Fig. 34 View FIGURES 22 – 35 ).
Discussion. This species has been recorded from Laos, Thailand, and Vietnam ( Polhemus & Andersen 1984, Zettel & Chen 1997, Zettel 1998, Chen et al. 2006). In Thailand, this species has been collected previously in Chiang Mai and Phetchabun provinces ( Polhemus & Andersen 1984, Zettel & Chen 1997, Chen et al. 2006). In the Phetchabun Mountain Range, we collected this species from rock pools, leaf packs, and stream margins. This species occurred synoptically with A. aquafrigida at a stream behind the headquarters of Nam Nao NP. Zettel and Chen (1997) recognized populations of A. velaris from Thailand and Vietnam as allopatric subspecies based on the length of the parameres in males and the pilosity on the connexival margin of sternite VII in females. More specifically, specimens from Chiang Mai are referred to as Amemboa velaris velaris . In the same publication, the specimens from Phetchabun Province were referred to as Amemboa velaris intermediate because they exhibited intermediate character states between the two subspecies in Thailand and Vietnam ( Zettel & Chen 1997).
