Description (Holotype). Adult male. Size: ABL 8.4 mm. Color/Luster: Dorsum shiny black, venter piceous. Mouth parts, first two antennomeres, and legs testaceous. Elytra strongly iridescent. Microsculpture: Mesh absent on dorsum at 80× magnification. Head: HW/PW = 0.70. Pronotum: PL/ PW = 0.66. Sides somewhat straightening and converging posteriorly toward obtuse hind angles. Bilateral basal impressions with punctules dense; sparse laterally on evenly convex hind angle areas. Anterior angles strongly projected forward. Elytra: Seriate setigerous punctures in striae 2, 5, and 7 small. ABS1 well developed, longer than maximum width of interval 2. Intervals with sparse, very fine punctules. Venter: Prosternal process like that of

subgenus. Ventrites with dense, very short pubescence. Ventrite 6 with 1 pair of anal setae. Legs: Male protarsi and mesotarsi typical of genus. Metatibia length like that of species group. Median lobe: Bulb narrow; dorsoapical plate abruptly narrow, markedly sinuate with tip recurved abruptly ventrad. Endophallus is without spines or welldefined macules.

Variation. ABL 7.3–9.0 mm. Pronotum brownish in teneral specimens. Females with tarsi unmodified; with 2 pairs of anal setae.

Etymology. The specific name is derived from Latin masculine adjective undatus , in reference to the wave shape of the median lobe.

Diagnosis. Selenophorus undatus is limited to Texas and Mexico where it is distinguished from other species of Selenophorus by its shiny and iridescent black elytra, dorsal microsculpture absent, pronotum not notably cordate, elytral striae not densely punctulate, abdomen without subapical carinae in males, and body length at most 9 mm. It is most similar to S. trepidus , but that precinctive species is limited to southern Florida. Examination of the male genitalia is the most reliable way to distinguish species. Compared to the females of S. trepidus , the stylomeres in S. undatus are shorter, evenly curved with smaller radius.

Type Habitat. The holotype was collected at the La Coma 1 tract within the La Coma unit of the Lower Rio Grande Valley National Wildlife Refuge LRGVNWR. This 12.9-hectare site is a restored mid-valley riparian woodland habitat ( King 2015) that was formerly agricultural fields and was purchased to become part of the LRGVNWR. The La Coma 1 tract was revegetated with native plant seedlings in October 1995, fourteen years before the start of the LRGV beetle biodiversity project.

Remarks. This common species occurs throughout the southern two-thirds of Texas and extends southward to Oaxaca in southern Mexico. Texas examples were present in most of the institutional collections that we studied. Specimens previously labeled “ Hemisopalus sp. UASM-5” are conspecific with S. undatus . Surprisingly, this species has remained undescribed until now.
