Agrilus pseudosallei Hespenheide , new species

( Figs. 6, 7 )

Holotype male: Length 3.90 mm, width 1.10 mm; slender, in cross section flattened above, moderately convex below; black with vague reddish-coppery reflections on front and below, pale golden reflections on pronotum, elytra with reddish-coppery reflections except along suture on anterior 1/2 and in transverse glabrous area from middle to posterior 3/4; setae pale and recumbent, short, sparse and relatively inconspicuous beneath, denser on dorsal portions of abdominal ventrite 1, lower 1/2 of front, on lateral margins and medial depressions of pronotum, on each elytron in small spot in basal depression, in J-shaped fascia along costa to margin at basal 1/4 to 1/2, and in fascia on apical 1/4 ( Fig. 6 ); setae dense and semi-erect on prosternum and in small patch on base of abdominal ventrite 1 at midline.

Head with front very convex, but narrowly depressed along midline, surface smooth, finely punctate; epistoma between antennal insertions narrow, 2/10 width of distance between inner margins of eyes, nearly transverse below, eyes small, oval, antennae serrate from antennomere 5, antennomeres 5–11 rounded-triangular. Pronotum subequal to elytra at posterior margin, with sides shallowly expanded outward then slightly converging to apex; marginal and submarginal carinae slightly undulate, joined for basal 1/4 when viewed from side; from above anterior margin broadly rounded; basal margin nearly transverse, slightly emarginate before middle of each elytron and scutellum; disk rather flat, with distinct depression along basal 1/2 of midline, a small transverse depression at apical 3/4, and oblique depressions interior to and in front of prehumeral carinae to lateral margins; prehumeral carinae strong, nearly straight, almost 1/2 length of pronotum; surface weakly transversely rugose. Scutellum pentagonal with transverse ridge. Elytra subequal in width at humeri and beyond middle, lateral margins slightly narrower between, apices broadly, separately rounded, minutely toothed; disk slightly convex in cross-section and from the side, each elytron with oval depression at base and narrower, raised spot along suture at basal 1/4, almost indistinct costa along suture to apex; surface transversely imbricate-punctate, smoother in blue area, more rugose at base. Prosternum with sides of prosternal process slightly narrowing between coxae, rounded-truncate at apex, prosternal lobe narrow, nearly transverse. Legs with first metatarsomere 1–1/2 length of second, tarsal claws similar on all feet, cleft with short inner tooth. Posterior margin of metacoxae slightly emarginate, nearly straight, upper angles obtusely rounded. Abdomen with suture between ventrites 1 and 2 faintly indicated at sides. Genitalia as in Fig. 7 .

Allotype female: As male except 4.05 mm long, 1.20 mm wide; uniformly sparsely setose below.

Type specimens: Holotype ( UNAM), México, Morelos, 2.5 km N, 4 km W Huautla, Est. CEAMISH, 940 m, 18°28’ N 98°02’ W, 19-VI-97, R. L. Westcott; allotype, same data as holotype ( RLWE).

Paratypes, México, Guerrero, 8 mi W Iguala, 18-VII-84, J. B. Wooley 84-041 (1, TAMU); Morelos, same data as holotype (3, RLWE), and 10.VII. 96, R. L. Westcott (2, RLWE); Sa. Huautla Reserve, 2.5 km W Ajuchitlán, 950m, 18°28’ N 99°00’ W, 9-VII-1996, R. L. Westcott (1, RLWE).

Discussion: Agrilus pseudosallei differs from A. sallei in many details, including color and setation patterns and male genitalia, but most conspicuously in having strong prehumeral carinae and the apices of the elytra entire and rounded, whereas A. sallei has indistinct prehumeral carinae and deeply emarginate elytral apices. Males measure 3.00– 3.90 mm long (mean = 3.40 mm for 3 specimens), and females measure 3.10– 4.65 mm long (mean = 3.92 mm for 6 specimens).

Etymology: The name reflects the similarity of this species to A. sallei Dugès.
