Aneflomorpha aculeata (LeConte)

( Fig. 1a View Figure 1 , 5a View Figure 5 , 7a View Figure 7 , 8a View Figure 8 , 9a View Figure 9 , 10a View Figure 10 , 16a View Figure 16 )

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 View Figure 1 ). Integument rufous ( Fig. 1a View Figure 1 , 16a View Figure 16 ). Antennae not or weakly carinate ( Fig. 9a View Figure 9 ). 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 View Figure 9 ). 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 View Figure 5 ). Elytral apices moderately to strongly bispinose in most specimens, some without produced apical spines ( Fig. 8a View Figure 8 ). Elytral pubescence white or off-white, with very numerous long, erect setae in addition to recumbent and recurved setae ( Fig. 7a View Figure 7 ). Procoxal cavities moderately open by over two-thirds the width of the broadly expanded prosternal process ( Fig. 10a View Figure 10 ). Protibia slender, gradually widening apically with the dorsal margin straight and non-carinate (as in Fig. 11h View Figure 11 ).

Discussion. Aneflomorpha aculeata is most similar to A. texana , A. linsleyae and A. subpubescens in 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. aculeata as in A. linsleyae which has the erect and suberect setae of more uniform length and distribution ( Fig. 7j View Figure 7 ). This feature also distinguishes A. aculeata from A. seminuda Casey ( Fig. 7s View Figure 7 ) and A. subpubescens (LeConte) ( Fig. 7t View Figure 7 ) which have more uniform length and distributed setae on the elytra and appendages (mostly recumbent and recurved in A. seminuda and straight and erect or suberect in A. subpubescens ). Aneflomorpha aculeata differs also from A. linsleyae in having the base of the protibia slender and gradually widening apically with the dorsal margin straight and non-carinate while in A. linsleyae the 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 View Figure 11 ). The antennae are moderately carinate in A. linsleyae ( Fig. 9i View Figure 9 ) while not carinate or weakly so in A. aculeata ( Fig. 9a View Figure 9 ). Most specimens of Aneflomorpha aculeata usually have strongly or moderately bispinose elytral apices ( Fig. 8a View Figure 8 ), while in A. linsleyae , the apices are usually bidentate, without spines ( Fig. 8i View Figure 8 ). Aneflomorpha aculeata is not known west of Texas while A. linsleyae is known only from the Chiricahua Mountains in Arizona. The very long, acute spines of the third and usually fourth antennomeres further distinguish A. aculeata from the superficially similar A. seminuda and A. subpubescens which have much shorter spines ( Fig. 9p,q View Figure 9 , 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. aculeata distinguish it from A. subpubescens which has larger pronotal punctures and typically fine, white scutellar pubescence. Aneflomorpha texana can be distinguished by the near absence of recurved, recumbent elytral setae (the setae are straight) ( Fig. 7w View Figure 7 ), the pronotum having a pronounced median callus in most specimens ( Fig. 6w View Figure 6 ), a dentiform or absent spine on antennomere 4 in most specimens ( Fig. 9t View Figure 9 ), and the outer elytral apex rounded to dentiform ( Fig. 8u View Figure 8 ).

Note that some A. aculeata from Texas and Oklahoma are not typical and have reduced elytral and antennal spines as well as less prevalent long, erect setae. These are somewhat intermediate with A. seminuda and some have been found mixed with specimens identified as A. subpubescens due to their similar size and coloration. They are tentatively assigned to A. aculeata in 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 Mexico and a range extension considerably south of the previously known distribution.
