Description (Holotype). Adult male. Size: ABL 5.2 mm. Color/Luster: Dorsal color as for that of species group. Antennomeres 1 — 3, mouthparts, legs, and much of venter testaceous; abdomen darker. Elytra strongly iridescent. Microsculpture: Pronotum with mesh obsolete. Elytra with striate microsculpture weakly impressed, more distinct laterally. Head: HW/PW = 0.76. Eyes moderately large. Pronotum: PL/PW = 0.67. Sides convergent nearly straight toward distinct obtuse hind angles. Base smooth, impunctate. Elytra: Common structural features of the species group. Venter: Prosternal process like that of subgenus. Ventrites with sparse, inconspicuous pubescence. Ventrite 6 with 2 pairs of anal setae.

Legs: Male protarsi and mesotarsi typical of genus. Metatarsi dorsally with conspicuous setae. Median lobe: Dorsoapical plate moderately long, with prominent but short, curved dorsal hook. Endophallus with massive lamina filling large ostium; proximally with 2 dark parallel fields of long microtrichia or slender spines.

Variation. ABL 4.5–5.2 mm. Females with microsculpture distinctly striate on elytra, weakly striate on pronotum; tarsi unmodified; 2 pairs of anal setae as in males.

Etymology. The specific name is derived from Greek neo (new) prefixed to ruficollis , in reference to the close resemblance to S. ruficollis .

Diagnosis. Selenophorus neoruficollis is distinguished from the other two species in the S. ruficollis species group by its limited northern range in southcentral USA and the presence of dorsal microsculpture that is not well impressed. In addition, males have a massive lamina in the ostium.

Type Habitat. The holotype was collected approximately 5 km SW of the city of College Station, Texas, within half a mile of the Brazos River.This area is located within the Post Oak Savannah Ecoregion of central Texas and is characterized by rolling hills with sandy soils and scattered clumps of trees, primarily post oaks. Forested bottom lands along creeks and rivers typically have clay-loam or clay soils.

Remarks. Compared to S. neoruficollis , S. pararuficollis of South America is slightly larger; dorsal microsculpture strongly impressed; elytra only faintly iridescent; pronotum with hind angles clearly subdentate, sides more evenly curved, finely rugose basomedially; antennomeres slightly longer; venter with dense, conspicuous pubescence; same sexual dimorphism + ♂ 2 — ♀ 2. See the holotype account for S. pararuficollis below.
