Selenophorus chaparralus Purrington ( Fig. 29 )

Selenophorus chaparralus Purrington 2000: 9 . Type locality: Texas ( Amistad Reservoir , Val Verde Co.) . Types: USNM.

Descriptive Notes. Body size small, ABL at most 8.0 mm. Ventrite 6 of male with pair of small carinate prominences. Elytra very shiny, iridescent bluish black, contrasting with dark reddish-brown forebody. Head and pronotum proportionately small relative to elytra. Pronotum with hind angles broadly rounded, with base narrower against elytra. Elytral intervals distinctly convex, finely and irregularly micropunctulate. Median lobe has short inflation near middle, apical 1/5 bent abruptly dorsad and with a very short ostium; apical tip a knob-like process hooked in opposite directions. ABL 7.5–8.0 mm.

Range. USA: sTX; Mexico *.

Remarks. The males of both S. chaparralus ( Fig. 29 ) and the Mexican species S. tubericauda share a similar bilateral pair of carinae near the apex of ventrite 6. Superficially resembling S. chaparralus and approaching the southern limit of S. chaparralus in northeastern Mexico, S. tubericauda is distinguished primarily by its dark appendages (palps, antennae, legs), dark forebody not tinged reddish, and elytra relatively dull due to distinct microsculpture mesh. The latter feature places S. tubericauda in the concinnus group. The aedeagus in one studied male from the state of Querétaro in central Mexico is normally shaped without the abrupt bend in median lobe as seen in S. chaparralus .
