Material. "15151 Padilloth. semiostrinus ES. Pn. malayana (Cb.m.)" coll. Simon, NH Museum, Paris. Proszynski 1987. Atlas ...: 104-105.

Diagnosis. Key characters are shown on Fig. 28 F-L, comparison with similar genera is shown on Fig. 28 A- D.

Description. Identifiable by unusual membranous copulatory ducts, large and very broad, semi arching in anterior half of epigyne ( Fig. 28L ), followed by much thinner straight portion running anterior-wards, ending by small spermathecae at the anterior end of epigyne. Epigyne externally broad oval, with small posterior medial pocket ( Fig. 28F ). Embolus lateral to anterior half of bulbus, relatively thick ( Fig. 28H ). Unusual protuberance with black, short setae in front of spinnerets, ventrally on female abdomen ( Fig. 28J ). Genital characters mentioned above and illustrated on Figs 28 K-L. Body shape ( Fig. 28F ) resembles genera included by Simon (1901-03) into Bavieae group, but that is not confirmed by other characters. Broad and large membranous ducts occur also in genera Mogrus and Philaeus , but differently shaped, and their palps are entirely different.

Distribution. Malaysia: Malay Peninsula.
