(Fig. 2i, 6s, 7s, 8q, 9p, 10s, 11i, 16f)
Aneflomorpha seminuda Casey 1912: 294.
Diagnosis. Length 11–16 mm, pronotum as long as wide, elytra together 3.40 times longer than wide (Fig. 2i). Integument light testaceous. Basal antennomeres very weakly carinate (Fig. 9p). Spine of third antennomere slightly longer than second antennomere and spine of fourth antennomere, projecting away from antennal plane less than 35 degrees, acute at apex (Fig. 9p). Pronotum with dense punctures of uneven size and placement, some contiguous and others not; punctures mostly unobscured by fine, recumbent pubescence; some specimens with a very small impunctate, post-median callus (Fig. 6s). Elytral apices strongly bidentate and concave between projections (Fig. 8q). Elytral pubescence fine, translucent and off-white, recumbent and recurved, with a few scattered long erect to suberect setae (Fig. 7s). Procoxal cavities narrowly open by less than half the width of the broadly expanded prosternal process (Fig. 10s). Protibia slender, gradually widening apically with the dorsal margin straight and non-carinate (Fig. 11i).
Discussion. Aneflomorpha seminuda is most similar to A. rectilinea in size and coloration. Aneflomorpha rectilinea has prominent antennal carinae and a well-developed spine on the third antennomere (Fig. 9o). In A. seminuda, the antennal carinae are barely evident, the spine of the third antennomere is only a little longer than the second antennomere and the spine of the fourth antennomere, and it does not project from the antennal plane by more than 35 degrees (Fig. 9p). The pronotum in A. rectilinea is longer than wide (Fig. 6q, r), unlike that of A. seminuda which is about as wide as long (Fig. 6s). As discussed in the A. rectilinea account, most specimens of that species have gradual darkening of the elytral apices and/or sternites (Fig. 1d, 2h, 16d, e) unlike A. seminuda which has more uniform testaceous coloration without darkening of the elytral apices or abdominal sternites (Fig. 2i, 16f). Although A. rectilinea is highly variable, on average, that species has longer, narrower proportions (elytra averaging 3.7 times as long as wide) compared to A. seminuda (elytra 3.4 times as long as wide). Material of the common and widespread A. rectilinea (especially from Texas and Oklahoma) should be carefully reviewed for potential misidentified specimens of A. seminuda. Chemsak (1962) stated that A. texana (formerly A. werneri) is closely related to A. seminuda, but they share few similar features and A. texana is herein removed from synonymy. The mostly suberect setae of the pronotum and elytral base in A. texana and relatively sparse recumbent setae and presence of a well-developed antennal carina distinguishes it most easily from A. seminuda which has mostly recurved, recumbent pubescence (Fig. 7s) and lacks a distinct carina on the basal antennomeres (Fig. 9p). Aneflomorpha seminuda is similar to A. fisheri, but has more symmetrically bispinose elytral apices (Fig. 8q) unlike the apicolaterally dentate and suturally spinose apices of A. fisheri (Fig. 8f).
Distribution and biology. This species, known only from Texas, has likely been misidentified previously (e.g., Turnbow and Wappes 1978; Lingafelter and Horner 1993), so distribution records in southern and northern Texas, respectively cannot be confirmed.
Material examined. USA: Texas (no further data) (holotype, USNM); Dickens Co., White River Res., Fermented Bait Trap, 11 July 1988, R. F. Morris (DJHC); Dickens Co., 7 mi. W. Dickens, 27–28 July 1981, Marlin E. Rice (2, TAMU); Crosby Co., 8 mi. E. Crosbyton, 4 August 1980, Marlin E. Rice (3, TAMU); Parker Co., Brazos River at Dennis, E. G. Riley, 24–25 June 1989 (EGRC).
