Artoadenus similus OPITZ , nov.sp.

( Figs . 82, 133, 134 , 149 , 174 )

Holotype: ♂. México: Jalisco, Puerto Los Mazos, 9 mi NW Autlan , VIII-28-1970, M. S. & J. S. Wasbauer ( WFBM).

Diagnosis: This is the only member of Artoadenus that is distributed in Middle America.

Description: Size: Length 14.0 mm; width 6.0 mm. Form: As in Fig. 149 . Color: Cranium mostly black, vertex with small flavotestaceous streak; pronotum mostly flavotestaceous, disc with two paralateral black streaks; mesoscutellum flavotestaceous; elytra bicolorous, humeral margin brown, disc mostly black, with wide flavotestaceous fascia. Head: Antennal capitulum long ( Fig. 82 ), each capitular antennomere longer than combined length of funicular antennomeres; antennal carina very prominent; EW/FW 23/25. Thorax: Pronotal anterior margin not projected at middle, side margin of disc parallel in anterior two-thirds; PW/PL 92/87; elytral disc strongly explanate at sides, carina not present; EL/EW 390/120. Abdomen: Male pygidium not incised at distal margin; aedeagus ( Figs. 133, 134 ); phallic apex very large.

Natural history: The holotype was collected in August.

Distribution ( Fig. 174 ): Known only from the type locality.

Etymology: The trivial name similus stems from similis (= like), is a Latin adjective. I refer to the shared superficial similarity between the members of this species and congeners.
