Toxognathus bakeri Fleutiaux, 1940

( Figs. 7 A-D; 34F)

Toxognathus bakeri Fleutiaux, 1940b: 104 .

Redescription (male, Fig. 34F ): Integument very bright, evenly light brown. Total length 6.0 mm; elytral base 1.0x as wide as pronotum, elytra 2.9x longer than pronotum. Frons flattened; frontal carina complete. Antennae surpassing the posterior angles of pronotum by one antennomere. Mandible unidentate. Pronotum ( Fig. 7A ) weakly convex 1.17x wider than long with sides sinuous converging abruptly anteriad from anterior half, lateral carina prominent posteriorly, directed ventrad anteriorly, posterior angles divergent and convex; punctures 0.5-1.0 diameter apart. Elytral interstices slightly convex. Free margin of metacoxal plate ( Fig. 7B ) short, triangular; tibiae slightly widened apicad, out- er angle of protibia truncate. Tergite IX with anterior margin straight.

Aedeagus ( Figs. 7C, D ): With phallobase 0.43x total length of aedeagus, 1.1x longer than wide, length ratio between lateroposterior and median parts 8.16; paramere with ventral anteromedian margins narrow, elongate and convergent; basal struts 0.33x total length of penis; ventral sclerite linear.

Holotype: [Island of Penang, Baker], [ Toxognathus bakeri Fleut. , type, Collection Fleutiaux], [Type], [Muséum Paris, Coll. E. Fleutiaux], [ Toxognathus bakeri (Fleutiaux) , J. Chassain det. 05], [Lectotype], (MNHN).

Distribution: MALAYSIA. Penang: Penang Island.

Remarks: Toxognathus bakeri is similar to T. dohertyi mainly because of its light brown integument and the prominent lateral carina of pronotum, but differs from this species in its smaller size, lighter integument, flattened frons, pronotal punctures smaller and not coalescent and elytral interstices less convex. It shares with T. beauchenei the produced ventral anteromedian margin of the parameres.
