Laemophloeus terminalis Casey, 1884: 82   ,83

Types: Casey (1884) noted he had a “...full series of this fine species before me from the cabinet of Dr. LeConte, also two specimens from Mr. Schwarz, all from Texas. In the USNM, I have examined four specimens of this species with the following label data: 1, “Tex”/“Casey bequest 1925”/“TYPE USNM 49153"/“ Laemophloeus terminalis Csy   ” / “ LECTOTYPE Laemophloeus terminalis Casey, 1884: 82   ”; 1, “Tex”/“Casey bequest 1925”/“terminalis PARATYPE USNM 49153"; 1, “Columbus 7.6 Texas ” / “CollHubbard andSchwarz”/“ L. terminalis Casey.   ” [folded]/“CoType No. 4655 U.S. N.M.”/“ Laemophloeus terminalis Casey   ”; 1, “Columbus 6.7 Texas ”/“CollHubbard andSchwarz”/“ L. terminalis Casey.   ” [folded]/ “CoType No. 4655 U.S. N.M.”. Casey (1884) did not designate a holotype. In the interests of nomenclatural stability, I designate the first listed specimen as lectotype.

Diagnosis. The combination of glabrous dorsal surface, testaceous coloration with darkly infuscate elytral margins forming a pale discal macula ( Fig. 16), simple scape ( Fig. 47 View Figures 47-50 ) and curved antennomere XI ( Fig. 50 View Figures 47-50 ) are diagnostic for this species. The male genitalia resemble those of L. suturalis   , but are even broader ( Fig. 48 View Figures 47-50 ). Length, 2.6mm - 4.1mm.

Distribution. Texas, east to Mississippi and north to Oklahoma.

Specimens examined. 175 from the following collections: BYUC, FSCA, TAMU, USNM.

NW Llano   ; Milam Co.: Fort Sullivan   ; San Jacinto Co.: Big Creek Scenic Area   ; San Patricio Co.: Welder Wildlife Refuge   ; Starr Co.: Santa Margarita Ranch   ; Tarrant Co.: Arlington   ; Limestone Co.: Mexia   ; [state label only].

Discussion. As noted above, this species is close to L. suturalis   and L. insulatestudinorum   , and it may be an extreme form of the former, although the consistent color pattern, elongate and curved antennomere XI, and very broad basal plates argue for its status as a separate species.
