description: Aneflomorpha linearis (LeConte)
(Fig. 1i, 2g, 5i, 6o, 7i, o, 8h, n, 9h, n, 10i, o, 11e, 15a, b, d, f, h, 16c)
Elaphidion lineare LeConte 1859: 80.
Aneflomorpha longipennis Casey 1912: 472. Synonymy by Linsley (1963: 57).
Aneflomorpha parowana Casey 1924: 242. New synonym.
Aneflomorpha testacea Casey 1924: 243. Synonym of parowana by Linsley (1963: 56). New synonym.
Aneflomorpha elongata Linsley 1936: 473. Synonym of parowana by Linsley (1963: 56). New synonym.
Aneflomorpha californica Linsley 1936: 476. Synonym of parowana by Linsley (1963: 56). New synonym.
Diagnosis. Length 9–17 mm, pronotum averages 1.05 times longer than wide, elytra together average 3.55 times longer than wide (Fig. 1i, 2g). Integument testaceous (Fig. 1i, 15a, b, d). Antennae carinate (Fig. 9h, n). Spine of third antennomere slightly longer than second antennomere, projecting away from antennal plane by less than 45 degrees, acute at apex (Fig. 9h, n). Pronotum with moderately dense punctures partially obscured by pubescence; usually with small, irregular, impunctate, post-median callus (Fig. 5i). Elytral apices most often weakly bidentate (Fig. 8h, n). Elytral pubescence white, sparse, mostly recumbent, with very few scattered long erect to suberect setae (Fig. 7i, o). Procoxal cavities broadly open by nearly twice the width of the barely expanded prosternal process (Fig. 10i, o). Protibiae flattened and carinate at base (Fig. 11e).
Discussion. When Elaphidion lineare LeConte, 1859 was transferred to the new genus Aneflomorpha (feminine in gender) by Casey (1912), lineare should have been changed to linearis to agree in gender. It is corrected herein. When Casey (1924) described A. parowana, he compared it to A. linearis and differentiated it as being “a little larger, less pallid in color, with larger eyes, more deeply and densely punctured pronotum, and slightly longer hairs of the elytra.” Examination of the primary types of both species (Fig. 1i, 2g, 15a, b, d) and their synonyms demonstrates that these characters are trivial, in some cases mischaracterized, and not of value for discriminating the species. My determination is that A. parowana (Fig. 2g, 15b, f) is a new synonym of A. linearis, rendering that species as the single Aneflomorpha occurring in the western coastal states of the United States. The holotypes of all the synonyms of A. parowana of Linsley (1963) (A. testacea Casey, 1924, A. elongata Linsley, 1936, and A. californica Linsley, 1936) were examined and are determined to be new synonyms of A. linearis as well.
Aneflomorpha linearis is most similar to a new species described herein, A. paralinearis Lingafelter, new species, from Arizona and New Mexico (Fig. 2e, 11g, 15c, f, g, i) due to the laterally flattened protibia with a dorsal carina at the base, open procoxal cavities, and carinate antennae. That species is distinguished by its larger average size, more rufous or brunneous rather than testaceous coloration, more strongly bidentate or bispinose elytral apices, more abundant erect elytral setae, as well as differences in the mesosternum and aedeagus as discussed in the description of A. paralinearis. Aneflomorpha yumae (elevated from subspecies level herein) shares the feature of having the base of the protibiae flattened, carinate dorsally, and as thick at the base as at the apex (Fig. 11j). It is distinguished by its relatively dense, thick, white, recumbent setae over much of the dorsal and ventral surface, particularly dense on the scutellum, inner eye margins, metasternum, and basal abdominal sternites (Fig. 3f, 16h), much denser than in A. linearis. The dense punctures of the pronotum are mostly hidden in A. yumae (Fig. 6x) and the pronotum usually lacks a callus unlike A. linearis which has the pronotal punctures mostly exposed and usually has a posteromedian impunctate callus (Fig. 5i). Another species from Arizona, A. linsleyae, also has the protibia moderately flattened at the base, however, it is not carinate dorsally. Aneflomorpha linsleyae is easily distinguished by its elytral pubescence consisting of only erect and suberect setae (Fig. 7j), whereas the elytral setae in A. linearis are mostly recumbent (Fig. 7i). Specimens of A. linearis resemble some lighter colored specimens of A. rectilinea, but the narrow protibial base which is not flattened (Fig. 11f, h) and nearly closed procoxal cavities of A. rectilinea (Fig. 10q, r) will easily distinguish that species.
Distribution and biology. This species was described from Fort Tejon, Kern County, California (LeConte, 1859). With the synonymy of A. parowana, the range is extended to the east to include Nevada, Utah, Colorado, and primarily northwest and central Arizona (Bezark 2022; Linsley 1963; Heffern 1998). Craighead (1923) records the larvae as being twig girdlers of Quercus species. Linsley (1963) records Q. agrifolia, Q. emoryi, and Q. arizonica as larval hosts. Tyson (1970) added Purshia tridentata (Pursh) as a host. One specimen examined for this study was collected on Purshia glandulosa Curran in the Hualapai Mountains in Arizona. Cope (1984) reared several specimens from Quercus dumosa Nuttall in Riverside Co., California and Adenostoma fasciculatum Hook. and Arn. in San Diego Co., California. Vlasak in Heffern et al. (2018) added two additional larval host records when he reared specimens from girdled stems of Ceanothus integerrimus Hook. and Arn. from El Dorado Co. and Rhus aromatica from Riverside Co., California. An additional specimen reared from Rhus sp. from Utah was examined.
