Curletti, Gianfranco, 2010, New species of the genus Agrilus Curtis, 1825, from Nicaragua and Panamá (Coleoptera: Buprestidae: Agrilinae), Zootaxa 2333, pp. 59-68 : 67

Agrilus disparifrons n. sp.

( Figure 10 )

Type specimens. Holotype 3: Nicaragua, Granada, Domitila, 07– 09.06.2004, leg. Eric van den Berghe and Heinz Dauber ( SMNS). Paratypes: 5 3 and 2 Ƥ, idem ( CMNG and MCCI); 2 Ƥ, idem ( CHAH).

Description of holotype. Length 5 mm. Uniformly dark bronze dorsally, with exception of green vertex. Vertex wider than 2/3 width of head, furrowed. Frons metallic green, with a dimple at base, covered with white pubescence; remaining surface glabrous. Eyes large, broader at base. Clypeus raised in regards to frons, separated by a transversal carina. Antennae serrate from antennomere 4. Pronotum wider on anterior side, regularly narrowed towards base, but with posterior angles right. Disc depressed at sides, and covered anteriorly with white pubescence. Sculpture superficial, longitudinal at sides and transverse in middle. Premarginal carina absent. Marginal carinae subparallel, separate at base. Scutellum large, transversely carinate posteriorly. Elytra with apices rounded and microdenticulate. Six (3+3) spots of white pubescence, first pair in humeral callus, second elongated from after callus to the middle of elytra, third rounded at posterior ¾ of elytra. White pubescence at base of first lateroterga and uniformly covering remaining laterotergae. Abdominal sterna with spots of same pubescence at base. White pubescence also on metepisternum and metecoxa. Claws mucronate. Metatarsus as long as metatibia, with first metatarsomere nearly as long as the sum of following four (1=2+3+4+5).

Description of paratypes. Length from 4.2 to 5.5 mm. In well preserved specimens, the pubescence on pronotum and sterna is pruinose. Females are distinguished by their bigger shape and by frons being yellowgold or copper. Aedeagus is thin, lengthened, with median lobe acuminate (figure 18).

Etymology. For sexual dichromism in the head.

Comments. A. disparifrons n. sp. is similar to A. limpiae Knull, 1941 described from the southcentral United States (Kansas, Oklahoma, Texas), but differs by these principal characters: smaller dimensions, premarginal carinula absent, marginal carinae of pronotum subparallel, not joined at base, presence of a pubescent dimple at base of frons, and aedeagus slender and lengthened.
