Crossidius wappesi Skillman, new species (Coleoptera: Cerambycidae) is described from Presidio County, Texas, USA.
I discovered a new species of Crossidius LeConte (Cerambycinae) in the fall of 2018 while collecting with Jim Wappes in Presidio County, Texas. Additional specimens were collected at the same location in 2019 by Jim Wappes and Kenneth Kuckartz.
This large, predominately western trachyderine genus presently contains 17 species and 37 subspecies (Bezark 2022). It should be noted that in the study of the genus by Linsley and Chemsak (1961), numerous popu­lations, known from short series, were mentioned, given short descriptions and left nameless. It is possible that a study utilizing DNA could result in a better understanding of the genus

Holotype male (Fig. 1–2, 5): Length 10.5–16 mm, elongate, parallel-sided, robust; head, legs, and antenna dark red-brown almost black; pronotum, thorax and abdomen rufo-testaceous; elytra testaceous. Head with pale blonde pubescence partially obscuring punctation which is contiguous and variable in size, all punctation smaller than that of pronotal disc. Antenna 11 segmented, long, extending three segments beyond elytral apex, dark red-brown becoming lighter towards apex; pubescence pale, short, recumbent, segments 3–5 densely pubescent on lateral surfaces, shining and very sparsely pubescent on dorsal and ventral surfaces; seg-ments 6–11 densely pubescent throughout; last segment slightly flattened, curved inward, terminus shiny, most specimens with an indented ring ⅓ from apex that looks to be the possible fusion of two antennomers. Prono-tum rufo-testaceous, shiny, margined with dark red-brown at apex and base; cylindrical, swollen, rounded at sides with a small, blunt, lateral tubercle; disc with 5 vague tubercles, (2 just before midline, 1 medially and 2 just before base, situated lateral to anterior pair) that are often darker than surrounding area; punctation contiguous, smaller than that of elytral base; erect and semi-erect pale pubescence moderate, not obscuring surface, ending at posterior margin of pronotum. Prosternum swollen at sides; punctation contiguous; erect and semi-erect pale pubescence moderate, not obscuring surface. Metasternum finely punctate, densely pubescent. Scutellar shield dark, indented medially, lateral edges elevated, small indentation before acute apex, pubescence long, sparse not obscuring surface. Elytra length 2.2 times width of both elytra at the humeri; testaceous with suture margin dark red-brown to basal ¼, often slightly expanded; surface moderately coarsely, densely punctate, becoming denser apically; pubescence short, blonde, sparse, recumbent, becoming semi-erect at basal ¼, not obscuring surface; apices truncate, inner angle usually dentate. Legs coarsely punctate thinly clothed with pale hairs, not obscuring surface. Abdomen densely pubescent and micro-punctate; pubescence consisting of recumbent and semi-erect hairs that partially obscure surface.Female (Fig. 3–4) Length 10.5–16 mm form similar to male except as noted. Black sutural band on apical ¾ covering about ⅔ of the width of the elytra over apical ⅓ then narrowing anteriorly to suture at basal ¼; elytral punctures of similar size but, more widely separated, pubescence somewhat longer, humeri sometimes black; Antenna 11 segmented, entirely dark red-brown, barely reaching apical ⅓ of body, pubescence very fine, darker than male, segments 7–10 somewhat serrate.Diagnosis. Crossidius wappesi drops out at couplet 14 in Linsley and Chemsak’s key to the species of Crossidius (Linsley and Chemsak 1961). This couplet contains two species: Crossidius hurdi, Chemsak and Linsley, 1959 and Crossidius pulchellus, LeConte, 1861. Crossidius wappesi is readily separated from these two species by having the pronotum rufo-testaceous not black as in both Crossidius hurdi and Crossidius pulchellus. Additionally, both Cros-sidius hurdi and Crossidius pulchellus have black antennae while those of Crossidius wappesi are dark red-brown.Type material. Holotype male labeled: USA: TX: Presidio Co., SR170, 3mi W. Ruidosa, 6-X-2018, Skillman & Wappes, ex flowers of Chrysothamnus ssp. It is deposited in the FSCA.Paratypes: 83 males and 19 females. Texas: Same data as holotype (8m, 2f – FWSC; 1m, 1f – SWLC; 1m, 1f – RFTC; 1m, 1f – DHCO), Presidio Co., Hwy 170, 7–12 mi W, Ruidosa, 6-X-2018, Skillman & Wappes, ex flowers of Chrysothamnus sp.

I take great pleasure in naming this new species in memory of James Earl Wappes, good friend, teacher, identifier, traveling companion and camping buddy. He finally got some work out of me!Remarks. The new species was found on flowers of a Chrysothamnus sp. growing by Hwy. 170 along a dip in the road where storm run-off was apt to flow. Other plants were found in similar circumstance. This area is frequently within sight of the Rio Grande and the state of Chihuahua, Mexico. I would expect to find this new species, in suitable habitat, on the Mexico side of the Rio Grande.A new species of Crossidius from Texas Insecta Mundi  0977 · 3AcknowledgmentsI wish to thank the following for help in this endeavor: Andrew Johnston, ASU, for early manuscript suggestions; Paul E.
