Abdullah, M.: A revision of the genus Retocomus Casey (Coleoptera, Anthicidae)

17. Retocomus wildii (LECONTE) (Figs. 147-157 ; Plate 1 : Map 3) Eurygenius Wildii LECONTE ([10] 1855, p. 270) ; LECONTE & HORN, ([11] 1883, p. 410). Retocomus wildii, CASEY ([7] 1895, p. 628). Diagnosis. The securiform apical segment of the maxillary palp (fig. 148), the deeply ridged and apically produced clypeus, and the stripes on the elytra should serve to distinguish this species from all others in the genus. Male (author's no. 473), U. S. A., Alabama (Dallas County?), Hazen, on Quercus priceus, April 4, in the British Museum (N. H.). Elytra with ten yellowish brown and black stripes or vittae, former due to pubescence. Vestiture dense. Head narrower Figs. 147—157. Retocomus wildii (LECONTE) 147: Mandible; 148: apical segment of maxillary palp; 149: seventh sternite of male, ventral view; 150: seventh tergite of 3, dorsal view; 151 : eight sternite of CJ, ventral view; 152: eighth tergite of <J, dorsal view; 153: tegmen of <J, ventral view; 154: median lobe of cj, ventral view; 155: apex of median lobe of 3, lateral view; 156: seventh sternite of 3, ventral view; 157: seventh tergite of 2, dorsal view than pronotum at its widest part. Clypeus deeply ridged and produced infront, partly concealing base of labrum. Median pronotal sulcus deep. Seventh abdominal sternite deeply emarginate; with (not much) long lateral processes or arms, and a prominent central process at apex; apically and subapically thickly spinous ventrally (fig. 149). Seventh tergite with a distinct median process at apex (fig. 150). Eighth sternite with a long, weakly emarginate central process, and a pair of short lateral processes at apex; membranous near base (fig. 151). Eighth tergite entire at apex (fig. 152). Parameres (fig. 153) slightly tapering at apex; with a pair of lateral spines near apex; with a weak, median, longitudinal ridge and a pair of snorter ridges present near apex; central longitudinal area less pigmented and slightly desclerotized. Median lobe as in figs. 154—155. Measurements in mm. Total length 9, Antenna! segments I— XI : 0,30, 0.19,
