singaporensis- group

Diagnosis (after Bayer 2012): Males with elongated tegulum (at least 1.5x longer than broad). The latter with broad basal half, turning abruptly into a narrower distal half ( Bayer 2012, fig. 15b). Conductor membranous and almost hyaline, thus may be difficult to recognise ( Bayer 2012, figs 84 h–i). Embolus with more or less round, platform-like, broad and flat base ( Bayer 2012, figs 15b, 17b).

Females with remarkably round receptacula ( Bayer 2012, figs 15f,h, 17e, 20b). Copulatory ducts medially curved.

The singaporensis -group includes the four species Psechrus singaporensis Thorell, 1894 , P. el ac h y s Bayer, 2012, P. norops Bayer, 2012 , and P. arcuatus Bayer, 2012 and is distributed in Singapore, Malaysia, (Southern) Thailand and Indonesia (Sumatra).
