Emertonius malayanus ( Edmunds & Prószyński, 2003)

Figures 21 K-P, 26B-E8

Myrmarachne malayana Edmunds & Prószyński, 2003: 317 , f. 101-109 (Dmf).

Myrmarachne malayana Yamasaki & Ahmad, 2013: 531 , f. 24A-G, 25A-E (mf),

Material. 1) Holotype male, paratype female " Malaysia (Peninsular Malaya) Genting Highlands, Natural History Museum, London, No. BMNH(E) 2002-34. 2) Male and female specimens from several localities in Sarawak and Sabah (Borneo), also two females from Sumatra: Pinag-Pinag quoted by Yamasaki & Ahmad (no information from where came specimens illustrated in that paper). 3) ten females and two males from various localities in Sabah photographed by P. Koomen. 4) Female from Brunei (Borneo) photographed by J. Koh.

Remarks. Identification of specimens listed above is uncertain, there are distinct differences in photos and drawings of epigyne enclosed (see Figs 26 B-S). The material described in paper of Yamasaki & Ahmad, came from distantly spaced islands and there are no information which specimens, and from where, are illustrated, the characteristics of epigyne as "Copulatory atria containing openings round" - which fits hundred of species of MYRMARACHNINES is insufficient. The whole description does not permit to define species. Therefore the only sure identification is that of type specimens from Genting Highlands ( Figs 21 KP), all remaining could be considered Emertonius cf. malayanus at best.

Diagnosis. Key characters are shown on Fig. 21 K-P, comparative background of remaining species shown on Figs 21 A-J.

Description. Resembles other species of Emertonius by shape and proportions of spermathecae ( Figs 21J ), especially by petiole-like proximal part of spermathecae, thinner and longer than in E. shelfordi ( Figs 21D ). Similarity of epigyne is not supported by difference in sloping thorax, distinctly lower than cephalic part, with a developed hump. Also abdomen is shorter and higher, with indistinct small anterior sclerite. Body color of fresh male and female is black ( Fig. 26 K-L, P-Q) with higher cephalic part, sloping thorax with a small hump on the slope. It differs from females, also black when live, but with high thoracal hump, separated from eyefield by distinct clevage accented by spot of white setae at its bottom, extended by delicate white line vertically on lateral surface. Variation of shape of epigyne and spermathecae is shown on Figs 26D 1-3 , E 5-8 , while Figs 26 G-G1, F, and H-H1 may represent different, relate species.
