Artoadenus dius OPITZ nov. sp. ( Figs 64 , 113, 114 , 147 , 175 )

Holotype: ♂. Panama, Pnma. Prov. K 8-13 El Llano-Carti Rd , 10-13 May 1996, Wappes Huether, & Morris ( FSCA). Paratypes: Three specimens. Panamá: Panamá: 7-11 km El Llano / Carti Rd. , 7-V-1999, Morris / Wappes ( JEWC, 1) ; Canal Zone: Barro Colorado Island , 3- VIII-1978, R.B. & L.S. Kimsey ( UCDC, 1). Venezuela: Tachira: La Morita , 8-14-IV-72, A. D’Ascoli, A. Montague, J. Salcedo ( WFBM, 1) .

Diagnosis: The metatibial glandular pit is prominent in the males of Artoadenus and Platynoptera . But, specimens of A. dius have subsecuriform terminal palpomeres, whereas Platynoptera specimens have securiform terminal palpomeres.

Description: Size: Length 12.0 mm; width 6.0 mm. Form: As in Fig. 147 . Color: Cranium bicolorous, upper frons and region behind eyes black, remainder flavotestaceous; pronotum mostly flavotestaceous, disc with two lateral black lines; mesoscutellum flavotestaceous; elytral disc mostly flavotestaceous, posterior third black. Head: Antennal capitulum very long ( Fig. 64 ), each capitular antennomere longer than combined length of scape, pedicel, and funicle; antennal carina very prominent; EW/FW 20/20. Thorax: Pronotal anterior margin not projected at middle; side margin of disc slightly rounded in posterior third; PW/PL 100/85; elytra moderately flared; EL/EW 180/55. Abdomen: Male pygidium not incised at distal margin; aedeagus as in Figs. 113, 114.

Variation: Size: length 12.0-15.0 mm; width 6.0-8.0 mm. The elytral disc may be entirely flavotestaceous, or mostly black with the basal margin and middle fascia flavotestaceous.

Natural history: Specimens were collected during April, May, and August. The specimen from Venezuela was collected at 300 m.

Distribution ( Fig. 175 ): Known from Panamá and Venezuela.

Etymology: The trivial name dius (= between) is a Greek adjective. I refer to the superficial similarities among specimens of Artoadenus, Platynoptera, and Tarandocerus.
