Aspitonis undulicornis OPITZ nov. sp.

( Figs . 68, 121, 122 , 153 , 174 )

Holotype: ♂. Mexico, Chis. Hwy. 190 , 10 mi. SE San Cristobal de las Casas, 7400'. A second label reads: 25 May 1983, C.W. & L. O’Brien 7 G.B. Marshall ( FSCA).

Diagnosis: The pronotum is mostly red and is without the midbasal dark line. This characteristic will distinguish the members of this species from congeners.

Description: Size: Length 5.5 mm; width 1.5 mm. Form: As in Fig.153 . Color: Cranium mostly red, region near antennal base and behind eyes narrowly black; pronotum mostly red, lower sides black; mesoscutellum yellow; elytral disc red. Head: Antennal capitulum very long ( Fig. 68 ), each capitular antennomere as long as combined length of scape, pedicel, and funicle; antennal carina very prominent; EW/FW 9/15. Thorax: Pronotal anterior margin not projected at middle, side margin of disc with shallow tubercle; PW/PL 34/34; elytral disc strongly deflexed at sides, carina not present; EL/EW 138/28. Abdomen: Male pygidium not incised at distal margin; aedeagus as in Figs. 121, 122.

Natural history: The holotype was collected during May, at 2256 m.

Distribution ( Fig. 174 ): Known only from southeastern México.

Etymology: The specific epithet undulicornis is a Latin compound name derived from unda (= wave) and cornu (= horn). I refer to the undulation of the anterior margin of antennomere 9.
