Laemophloeus apache Thomas   , n.sp.

Fig. 17-19 View Figures 17-19

Types: Holotype male, deposited in FSCA, with following label data: “ Arizona, St. Rita Mts. Madera Cyn. Sept. 14 1974 K. Stephan leg.”/ “ HOLOTYPE Laemophloeus apache Thomas   ”; allotype female, deposited in FSCA, with following label data: “ ARIZONA: Santa Rita Mts. , Madera Canyon. 31-VII-1974 G. H. Nelson ”/”ULTRAVIOLET LIGHT”/ “ ALLOTYPE Laemophloeus apache Thomas   ”.  

Diagnosis. The combination of densely punctate, pubescent dorsal surface; the dark dorsal coloration, ranging from reddish-brown to piceous; and the pale, distinctly longitudinal, elytral maculae, is diagnostic for this species. It is very similar to L. shastanu   s but larger (2.5-3.6mm vs. 2.0- 3.2mm) and more robust (compare Fig. 8 View Figure 8 with Fig. 14 View Figure 14 ). Male genitalia ( Fig. 18-19 View Figures 17-19 ) differ from other members of the biguttatus group in either number of primary setae (from L. biguttatus   and L. shastanus   ) or shape of basal plates ( L. fervidus   ).

Description: 3.6mm long; elongate-ovate; dorsal surface dark castaneous; mouthparts, antennae, legs, ventral surface, and an elongate macula confined mostly to the second elytral cell at about the basal third, paler ( Fig. 8 View Figure 8 ).

Head: 2.5× wider than long; epistome with emargination over labrum moderate, mandibular emarginations moderate, antennal emarginations shallow; frontoclypeal suture complete and distinct ( Fig. 17 View Figures 17-19 ); longitudinal line impressed; surface densely punctate, punctures about the size of an eye facet, separated mostly by about 1 diameter; pubescence inconspicuous, most evidence laterobasally, with punctures there subtending a short dark erect seta that barely emerges from the puncture; disc of head between punctures smooth and shiny, without microreticulation. Mandibles large, rather elongate. Eyes moderate, length 0.4× that of head ( Fig.17 View Figures 17-19 ). Antennae elongate, attaining about basal third of elytra; scape longer than broad; pedicel quadrate, about 0.5× length of scape; III elongate, 0.9× as long as scape; IV-VII elongate, subequal in length; each 0.7× length of scape; VIII slightly shorter than preceding, club comprised of IX-XI, IX-X each slightly expanded distally, IX, 0.9× length of scape; X, 0.8× length of scape; XI, 1.3× length of scape.

Thorax: Pronotum transverse, 1.9× wider than long; widest just behind apical angle; 1.4× wider apically than across basal angles; anterior angles right, not produced; hind angles obtuse, projecting; antebasal dentical distinct ( Fig. 17 View Figures 17-19 ); sublateral line with median fovea; punctation similar to head, punctures slightly smaller; pubescence more evident laterobasally; surface smooth and shiny between punctures, not microreticulate. Legs moderate; femora stout.

Elytra: 1.5× longer than wide; inner margin of cell 1 grooved only at apical two-thirds, outer margin of cell 1 absent; inner margin of cell 2 grooved from basal fifth, outer margin absent; inner margin of cell 3 absent at base but cell 3 otherwise complete; elytra punctures scattered, not arranged in rows; humeral carina well-marked; elytral surface conspicuously pubescent.

Male genitalia: ( Fig. 18-19 View Figures 17-19 ) parameres broadly triangular, apparently fused along medial margins except for narrow line distally; each paramere with 2 primary setae, one located near midline at very base, and a longer, finer seta located near laterobasal angle; laterobasal angle with patch of 4-5 fine setae; basal plates elongate, almost straight on mesal edge; curved on outer edge, outer basal angle acutely produced; flagellum slender.

Female allotype: 3.5mm long; head 2.6× wider than long, antennae shorter than in male, attaining base of pronotum; eye larger, comprising 0.5× length of head; pronotum 1.5× wider than long, not as narrowed basally as in male; elytra, 1.5× longer than wide, comprising 0.7× total body length.

Variation: Paratypes range in length from 2.5mm to 3.6mm; color ranges from reddish-brown to piceous.

Distribution. Southwestern U.S., from Texas to Arizona. Two specimens are excluded from the type series pending further collections of this species in California and Mexico to confirm its presence.

Etymology. This species is named for the Native American tribe whose territory roughly corresponds with that of the beetle. It is used as a noun in apposition.

Discussion. This narrowly distributed species was long confused by this author with L. shastanus   but is easily distinguished by genitalic characters.
