Aneflomorpha tenuis

description: Aneflomorpha tenuis (LeConte)
(Fig. 3b, 6u, 7u, 8s, 9r, 10u)
Elaphidion tenue LeConte 1854: 81.
Diagnosis. Length 12–15 mm, pronotum averages 1.30 times longer than wide, elytra together average 3.33 times longer than wide (Fig. 3b). Integument typically brunneous, sometimes rufous. Antennae not or inconspicuously carinate (Fig. 9r). Spine of third antennomere over twice the length of the second antennomere and nearly half the length of the fourth antennomere (Fig. 9r); projecting away from antennal plane by nearly 45 degrees, blunt at apex (Fig. 9r). Pronotum with small punctures throughout, except for narrow, elongate, impunctate median callus (Fig. 6u). Elytral apices truncate or rounded apicolaterally to a weakly dentate suture (Fig. 8s). Elytral pubescence white and translucent, with primarily erect and suberect setae and lacking recurved, recumbent setae (Fig. 7u). Procoxal cavities closed by broadly expanded prosternal process (Fig. 10u). Protibia slender, gradually widening apically with the dorsal margin straight and non-carinate (as in Fig. 11h).
Discussion. Although there are some exceptions, this species is typically darker brown and has a longer and narrower pronotum than most Aneflomorpha. It is unique in having the spine of the third antennomere very long (nearly half the length of the fourth antennomere), and blunt at the apex (Fig. 9r). Aneflomorpha volitans (LeConte) which is known only from Baja California, Mexico, is very similar in having an extremely long, blunt spine of antennomere three, however, most specimens of A. volitans are rufous in coloration rather than brunneous or testaceous as in A. tenuis and have widely open procoxal cavities unlike A. tenuis which has them closed (Fig. 10u). For similar species in the United States, only A. cazieri (Fig. 9b), A. delongi (Fig. 9e), and some A. linsleyae (Fig. 69) have a blunt spine on antennomere three. The latter two species are easily distinguished from A. tenuis by having only erect and suberect setae on the elytra, as well as having allopatric distributions with A. delongi (known only from Florida and Georgia) and A. linsleyae (known only from the Chiricahua Mountains in Arizona), while A. tenuis is known only from Texas. Specimens of A. cazieri are much smaller than A. tenuis and have open procoxal cavities (Fig. 10c) and have either a smaller or absent impunctate median callus (Fig. 5c) unlike A. tenuis which has closed procoxal cavities (Fig. 10u) and a pronounced median callus in most specimens (Fig. 6u).
Distribution and biology. This species is known from southern and western Texas and adjacent northern Mexico (Linsley 1963; Bezark 2022). Two records from Nuevo Leon (USNM) represent a new state record. Specimens have been mostly collected at lights from June through September. One specimen was collected from Baccharis. Linsley (1963) lists Acacia [now Senegalia] farnesiana as a larval host.
