Toxognathus fairmairei Fleutiaux, 1940

( Figs. 11C, D ; 34K )

Toxognathus fairmairei Fleutiaux, 1940b: 104 .

Redescription (male, Fig. 34K ): Integument dark brown with legs and ventral abdomen brown, antenna light brown. Total length 7.5 mm; elytral base 1.09x as wide as pronotum, elytra 3.14x longer than pronotum. Frons deeply concave along the anterior margin; frontal carina complete; eyes very small (IEP 0.23) ( Fig. 11D ). Antennae reaching the base of posterior angles of pronotum; antennomeres IV-X as long as wide and convex. Mandible bidentate. Pronotum weakly convex 1.20x wider than long with sides parallel from base of posterior angles to anterior third then convergent to anterior margin, lateral carina entirely lateroventral, posterior angles divergent and weakly convex; punctures less than 0.5 diameter apart; prosternum with a median longitudinal groove on posterior half and between procoxae. Elytral interstices convex. Free margin of metacoxal plate absent, tibiae slender with out- er angle truncate. Tergite IX with anterior margin straight.

Aedeagus: Phallobase 0.36x total length of aedeagus, 1.13x wider than long. Paramere with anteromedian margin acute, ventral sclerite linear.

Holotype: [Foutchien, De Latouche], [Collection Fairmaire], [Collection E. Fleutiaux], [ Toxognathus fairmairei Fleut. , type, Collection Fleuxiaux], [Type], [Muséum Paris, Coll. E. Fleutiaux], [ Toxognathus fairmairei (Fleutiaux) , J. Chassain det. 05], [Lectotype], male (MNHN).

Distribution: CHINA. Fujian.

Remarks: The aedeagus of the holotype was poorly preserved, with dark musculature and apex broken; therefore it was not possible to obtain all measurements. It is distinguishable from all Toxognathus species by the shape of prothorax, the very small eyes and the median longitudinal groove on the prosternum.
