Amemboa (Amemboa) aquafrigida Zettel and Chen 1997: Ann. Hist.-Natur. Mus. Nat. Hung. 94−96.
Diagnosis.Males of A. aquafrigidahave a proctiger with two pairs of caudally directed projections and a round tip ( Fig. 22). Further, the male profemur has three distinct hair patches ( Fig. 8), whereas A. javanicaLundbladhas a single hair patch and A. brevifasciata, A. cristata, and A. ripariaeach have two hair patches. Males of A. aquafrigidahave the proximal hair patch smaller than the other patches, whereas in A. speciosait is more than twice as large as the other patches.
Discussion. Amemboa aquafrigidais known only from Thailandand has been recorded from Nam Nao NP in Phetchabun and Chaiyaphum provinces ( Zettel & Chen 1997, Chen et al. 2006). In this study, this species was collected from rock pools and margins of streams in Nam Nao NP and Na Haew NP. Thus, this species appears to be endemic to the upper part of the Phetchabun Mountain Range. This species occurred synoptically with A. velarisin the stream behind the visitor center in Nam Nao NP and with A. ripariain a rock pool above Tahd Heuang International Waterfall in Na Haew NP.
