Elaphidion subpubescens LeConte 1862: 41 View in CoL .

Diagnosis. Length 15–20 mm, pronotum averages 1.20 times longer than wide, elytra together average 3.88 times longer than wide ( Fig. 3a View Figure 3 ). Integument mostly rufous, with head and pronotum usually distinctly darker testaceous. Antennae not or weakly carinate on basal antennomeres ( Fig. 9q View Figure 9 ). Spine of third antennomere very narrow, slightly longer than second antennomere and spine of fourth antennomere barely projecting from antennal plane, acute at apex ( Fig. 9q View Figure 9 ). Pronotum with pronounced punctures unobscured by pubescence, without median callus ( Fig. 6t View Figure 6 ). Elytral apices usually bispinose with apicolateral spine much broader and longer than sutural spine ( Fig. 8r View Figure 8 ). Elytral pubescence very fine, translucent or pale golden, erect and suberect, without recumbent and recurved setae ( Fig. 7t View Figure 7 ). Procoxal cavities open by more than the apical width of the prosternal process ( Fig. 10t View Figure 10 ). Protibia slender, gradually widening apically with the dorsal margin straight and non-carinate (as in Fig. 11h View Figure 11 ).

Discussion. This species, the type of the genus, is distinctive due to its large, uniform pronotal punctures, light rufous coloration with elytra usually lighter in color than the head and pronotum, and erect setae on the dorsal surface, without recumbent setae. This is one of only two species of Aneflomorpha known from the eastern United States ( Lingafelter 2007; Bezark 2022), the other being A. delongi ( Fig. 1f View Figure 1 ). Only these two species, along with A. linsleyae ( Fig. 7j View Figure 7 ) from the Chiricahua Mountains in Arizona, lack short, recumbent elytral pubescence. Aneflomorpha aculeata , which is sympatric with A. subpubescens along the western part of A. subpubescens range, especially in Texas and Oklahoma, is similar, but has recumbent pubescence mixed with erect and suberect setae ( Fig. 7a View Figure 7 ). These four species are also similar in having light rufous coloration over most of the integument. Aneflomorpha subpubescens is easily distinguished by the darker testaceous head and pronotum compared to the remainder of the integument which is rufous. In addition, its relatively short, acute spine on antennomere three ( Fig. 6q View Figure 6 ) distinguishes it from A. aculeata which typically has a longer spine. In specimens where the antennal and elytral apical spines are not pronounced, the finer pronotal punctation and typically ochraceous pubescence on the scutellum in A. aculeata distinguish it from A. subpubescens which has larger pronotal punctures and typically fine, white scutellar pubescence ( Fig. 6t View Figure 6 ). In A. linsleyae , the spine of antennomere three is subacute or blunt, and relatively longer, and the antennae are distinctly carinate ( Fig. 9i View Figure 9 ). In A. delongi ( Fig. 9e View Figure 9 ), the spine of the third antennomere is blunt and nearly half the length of the fourth antennomere. In A. aculeata , the spines of the third antennomere and elytral apices are typically very pronounced, and the integument coloration is more uniform rufous ( Fig. 1a View Figure 1 ), not darker on the head and pronotum as in most A. subpubescens .

Distribution and biology. This species is widespread through much of the eastern half of the United States ( Linsley 1963; Lingafelter 2007). Linsley (1963) and Lingafelter (2007) recorded Quercus (especially Q. alba ) and Castanea as larval hosts. Vlasak in Heffern et al. (2018) recorded larvae in saplings of Quercus ilicifolia Wangenh , Comptonia peregrina (L.) J. M. Coult., and Gaylussacia sp. in Burlington and Camden counties, New Jersey. These observations support Craighead (1950) and Linsley (1963) which state that A. subpubescens rarely develops in branches of mature trees and favors seedlings up to one inch in diameter.
