Elaphidion aculeatum LeConte 1873: 264.
Diagnosis.Length 10–16 mm, pronotum averages 1.20 times longer than wide, elytra together average 3.38 times longer than wide ( Fig. 1a). Integument rufous ( Fig. 1a, 16a). Antennae not or weakly carinate ( Fig. 9a). Spine of third antennomere at least 1.5 times as long as second antennomere, projecting away from antennal plane by less than 40 degrees, acute at apex ( Fig. 9a). Spine of fourth antennomere well-developed, acute, longer than second antennomere. Pronotum densely punctate with punctures of differing sizes and contiguous; unobscured by pubescence. Some specimens with small, narrow post-median callus ( Fig. 5a). Elytral apices moderately to strongly bispinose in most specimens, some without produced apical spines ( Fig. 8a). Elytral pubescence white or off-white, with very numerous long, erect setae in addition to recumbent and recurved setae ( Fig. 7a). Procoxal cavities moderately open by over two-thirds the width of the broadly expanded prosternal process ( Fig. 10a). Protibia slender, gradually widening apically with the dorsal margin straight and non-carinate (as in Fig. 11h).
Discussion. Aneflomorpha aculeatais most similar to A. texana, A. linsleyaeand A. subpubescensin having rufous coloration, moderately open procoxal cavities, densely punctate pronotum, and abundant erect and suberect setae on the elytra and appendages. The erect setae are longer, more abundant, and not as uniformly distributed on the body and appendages of A. aculeataas in A. linsleyaewhich has the erect and suberect setae of more uniform length and distribution ( Fig. 7j). This feature also distinguishes A. aculeatafrom A. seminudaCasey( Fig. 7s) and A. subpubescens(LeConte)( Fig. 7t) which have more uniform length and distributed setae on the elytra and appendages (mostly recumbent and recurved in A. seminudaand straight and erect or suberect in A. subpubescens). Aneflomorpha aculeatadiffers also from A. linsleyaein having the base of the protibia slender and gradually widening apically with the dorsal margin straight and non-carinate while in A. linsleyaethe base of the protibia is bulging and then narrowed distally, then widening apically such that the dorsal margin is slightly sinuate and weakly carinate dorsally at the base ( Fig. 11c). The antennae are moderately carinate in A. linsleyae( Fig. 9i) while not carinate or weakly so in A. aculeata( Fig. 9a). Most specimens of Aneflomorpha aculeatausually have strongly or moderately bispinose elytral apices ( Fig. 8a), while in A. linsleyae, the apices are usually bidentate, without spines ( Fig. 8i). Aneflomorpha aculeatais not known west of Texaswhile A. linsleyaeis known only from the Chiricahua Mountains in Arizona. The very long, acute spines of the third and usually fourth antennomeres further distinguish A. aculeatafrom the superficially similar A. seminudaand A. subpubescenswhich have much shorter spines ( Fig. 9p,q, respectively). 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. aculeatadistinguish it from A. subpubescenswhich has larger pronotal punctures and typically fine, white scutellar pubescence. Aneflomorpha texanacan be distinguished by the near absence of recurved, recumbent elytral setae (the setae are straight) ( Fig. 7w), the pronotum having a pronounced median callus in most specimens ( Fig. 6w), a dentiform or absent spine on antennomere 4 inmost specimens ( Fig. 9t), and the outer elytral apex rounded to dentiform ( Fig. 8u). Note that some A. aculeatafrom Texasand Oklahomaare not typical and have reduced elytral and antennal spines as well as less prevalent long, erect setae. These are somewhat intermediate with A. seminudaand some have been found mixed with specimens identified as A. subpubescensdue to their similar size and coloration. They are tentatively assigned to A. aculeatain this work, but further study may conclude they belong elsewhere.
Distribution and biology.Specimens have been encountered from May through September at lights, sugar and other fermented bait traps, and Lindgren Funnel traps baited with ethanol in central and southwestern Texas. Specimens were examined from eastern Oklahoma, southwestern Missouri, and northwestern South Carolina which represent three new state records for the species. One digital specimen, tentatively assigned to this species, was seen on BugGuide (BugGuide 2022) from Bibb County, Alabama (Alabama Museum of Natural History). No larval hosts have been documented for Aneflomorpha aculeata. Two specimens were examined from Coahuila, Mexico(TAMU), representing a new state record for Mexicoand a range extension considerably south of the previously known distribution.
