Agrilus goldsteini n. sp.

( Figure 4 )

Type specimens. Holotype 3: Mexico, Chiapas, 8 mi E Rizo de Oro, Hwv. # 190, 22.VI.1985. Askevold & Heffern ( MCCI). Paratypes: 1 Ƥ, Chiapas, 3 mi.SE La Trinitaria, 18– 19.06.1965.H.R. Burke, J.R. Meyer, J.C. Schaffner leg. ( CHAH); 1 3 and 1 Ƥ, Nicaragua, Matagalpa Dept., Cerro Iargo km 114, 28.V.2005, leg. E. van den Berghe ( MCCI and CMNG).

Description of holotype. Length 6.6 mm. Head and pronotum black. Elytra red on external half, with a black stripe on internal half, along suture. Vertex width more than 1/3 of anterior margin of pronotum. Frons flat, lightly furrowed, covered by regular white pubescence. Antennae black, short, serrate from antennomere 5. Pronotum strongly gibbous especially anteriorly, near anterior margin, convex. Lateral margins slightly arcuate, wider in middle, with posterior angles obtuse. Anterior margin gibbous. Disc with superficial sculpture, forming vertical striae, with exception of top of anterior hump, where it is rounded and concentric. Premarginal carinula regularly arcuate, not entire. Lateral carinae subparallel anteriorly, joining before base. Anterior edge of prosternal lobe rounded, entire. Prosternal plate truncate, enlarged at apex. Scutellum concave, without transversal carina. Elytra with apex rounded and microdenticulate. Black stripe along suture is posed in a small depression. All surfaces covered by short white pubescence, more condensed in perisutural depression, but always shorter than the pubescence present on frons and pronotum. Ventral side black, covered with regular white pubescence. Last visible sternite widely sinuate. Legs black. Anterior claws bifid, median and posterior mucronate. First metatarsomere shorter than sum of the following three (1<1+2+3). Aedeagus black, sclerotized, regularly widened anteriorly (figure 13).

Description of paratypes. Length 6.4 mm (3) and 7.3 mm (Ƥ). These specimens from Nicaragua have pubescence in perisutural sulcus of elytra more visible. Ventral side and legs with copper reflections. Female with anterior claws mucronate like median and posterior and color of external half of elytra copper instead of red.

Etymology. This species is named after a friend Jessica Goldstein, for her contributions in the management of the Lepidoptera collection of MCCI.

Comments. Concentric sculpture on the anterior hump of pronotum; conformation of prosternal plate; antennae dentate from 5th antennomere and scutellum concave without carina, make A. goldsteini n. sp. anomalous and unmistakable in the American Agrilus fauna. The color pattern of the elytra is similar to A. asperulus Waterhouse, 1889 . This latter differs by the smaller shape, transversal sculpture of pronotum, a rounded head, and premarginal carinula absent or barely visible.
