Diagnosis

Female with mesosoma bright green, pronotal dorsolateral angle obtuse, mesoscutum areolate, fore coxa yellow, terga with pairs of dorsolateral yellow maculations. Differs from H. callichroma by the acuminate-shaped anterior margin of mesoscutum, rounded in the latter, and the color of mid trochanter, yellow in the latter. The clypeus is areolate and the metasoma maculations are not connected as H. nitidus sp. nov. Male unknown.

Etymology

From the Latin ‘ acumen ’, ‘sharp point’, and ‘- atus ’, ‘having a condition’, referring to the acuminate-shaped anterior margin of mesoscutum.

Description

Female

HEAD. Head green with some coppery reflections; covered with sparse short white plumose setae. Labrum amber to light brown. Mandible yellow with darkened apex. Clypeus not depressed in the middle; green, with an apical band yellow, which is projected upwards in the center; covered with dense short white decumbent setae, intermixed with longer erect setae; punctulate; areolate between punctures. Supraclypeal area puncticulate; areolate between the punctures. Paraocular fovea narrow and extending from base of eye to the height of antennal socket, always contiguous to inner orbit. Paraocular area sculpturing similar to that of the supraclypeal area. Frons densely punctulate; areolate between the punctures. Gena covered with decumbent white setae. Scape yellow ventrally. Flagellum mostly dark brown, ventrally light brown to yellow.

MESOSOMA. Pronotal dorsolateral angle obtuse, or with a rounded aspect. Pronotal lobe yellow. Tegula amber with a yellow band on the inner margin. Wing membrane hyaline. Mesoscutum anterior margin acuminate-shaped; surface green; covered with very short tomentum and few sparse darker erect setae, more visible from an oblique view; densely punctulate; strongly areolate between the punctures. Mesepisternum bright green; areolate. Metapostnotum not depressed in the median posterior surface; bright green; entirely areolate to coriaceous.

LEGS. Fore coxa and trochanter yellow, femur brown with a yellow tip or ventrally, tibia yellow, basitarsus amber. Mid coxa and trochanter brown, femur, tibia and basitarsus amber. Hind leg brown. Hind femur with dense long plumose setae.

METASOMA. Terga dark brown with yellow maculations, as follows: T2 with two small, yellow, basolateral maculations, progressively increasing in size towards T5 where the yellow maculations occupy a third of the width of the tergum; covered with short decumbent setae very sparsely distributed in T1, which progressively become denser towards T5; integumental surface lineolate. Sterna covered with long plumose setae.

MEASUREMENTS. Approximate body length 5.04 mm. Head width 1.36 mm; length 1.14 mm. Clypeoantennal distance 0.29 mm. Distance between subantennal sutures 0.34 mm. Lower interocular distance 0.76 mm. Upper interocular distance 0.78 mm. Scape length 0.64 mm. Intertegular distance 0.96 mm. T1 width 1.1 mm. T2 width 1.34 mm. T3 width 1.44 mm.

Comments

Habralictus acuminatus sp. nov. is described based only on a single female which is similar to that of H. callichroma ; also, its type locality falls inside the distribution of the latter. However, the mesoscutum shape and the coloration of the mid trochanter are different between these species. These features do not vary among the several studied specimens of H. callichroma . We consider this as evidence enough to consider H. acuminatus as a separate species.
