Aneflomorpha texana Linsley

(Fig. 3c, d, 6w, 7w, 8u, 9t, 10w)

Aneflomorpha texana Linsley 1936: 473 . Synonym of seminuda Casey, 1912 by Linsley (1963: 51). New status. Aneflomorpha werneri Chemsak 1962: 106 . New synonym.

Diagnosis. Length 10–17 mm, pronotum averages 1.17 times longer than wide, elytra together average 3.10 times longer than wide (Fig. 3c, d). Integument light rufous. Antennae carinate (Fig. 9t). Spine of third antennomere about as long or a little longer than second antennomere, projecting away from antennal plane by less than 40 degrees, acute at apex (Fig. 9t); fourth antennomere usually dentiform or rarely with small spine. Pronotum with small, closely placed punctures, mostly unobscured by suberect and erect setae, usually with small to moderatesized impunctate, post-median callus (Fig. 6w). Elytral apices unevenly rounded apicolaterally, subtruncate to weakly bidentate (Fig. 8u). Elytral pubescence fine and translucent or golden, mostly straight, erect and suberect at base, but with some straight, semi-recumbent setae and very few recurved, recumbent setae (Fig. 7w). Procoxal cavities open by less than half the width of the broadly expanded prosternal process (Fig. 10w). Protibia slender, gradually widening apically with the dorsal margin straight and non-carinate (as in Fig. 11h).

Discussion. The holotype of A. texana Linsley was examined (Fig. 3c) and found to be conspecific with A. werneri Chemsak. The holotype of A. texana has distinct antennal carinae, lacks spines on the elytral apices, and lacks appressed setae on the pronotum unlike the holotype of A. seminuda (Fig. 2i) which it was considered closely related to (Chemsak 1962) and placed in synonymy by Linsley (1963). The only feature somewhat atypical of some populations is that the spine of antennomere four is more prominent in the holotype of A. texana than in some other specimens. Aneflomorpha werneri is therefore considered a new synonym of A. texana . The mostly suberect setae of the pronotum and elytral base in A. texana (and near absence of recurved, recumbent setae) and presence of a basal antennal carina distinguishes it most easily from A. seminuda which has mostly recurved, recumbent pubescence with few erect setae (Fig. 7s) and lacks a distinct carina on the basal antennomeres (Fig. 9p).

The combination of distinctive light rufous coloration, rounded or weakly dentate apical margin of the elytra, pronotum with small to moderately developed impunctate central callus, moderate antennal carina, reduced spine on the fourth antennomere, and setae on the pronotum and the base of the elytra being erect, suberect and straight (not recurved and recumbent) as in most Aneflomorpha, aid in making this species distinctive. Due to the rufous coloration, erect pubescence, and size, this species is similar to A. aculeata . That species differs in having an apicolateral spine on the elytra (Fig. 8a) and in having recurved, recumbent setae in addition to the straight erect and suberect setae on the elytra (Fig. 7a). From the less common rufous forms of A. tenuis, A. texana can be most easily distinguished by having a shorter, acute spine on antennomere three (Fig. 9t) as opposed to the long, blunt spine in A. tenuis (Fig. 9r). From A. opacicornis (transferred to Neaneflus herein), A. texana is distinguished by having the pronotal and basal elytral setae as described (Fig. 6w; 7w) unlike the recurved, recumbent setae in A. opacicornis (Fig. 6m, 7m). Further, A. texana has a more elongate pronotum with straight or less rounded sides (Fig. 6w) unlike A. opacicornis which has the pronotum slightly wider than long and broadly rounded at the sides and constricted basally (Fig. 6m). That species is further distinguished by having more rounded outer apical elytral apices (Fig. 8l, 17e, f).

Distribution and Biology. This species was previously known only from western Texas (Linsley 1936; Chemsak 1962; Linsley 1963). Specimens examined from New Mexico represent a new state record for A. texana in the United States and Coahuila represents a new state record and southernmost distribution for Mexico.
