Type specimens. Holotype 3: Nicaragua, Granada, Domitila, 07–09.VI.2004, leg. Eric van den Berghe und Heinz Dauber ( SMNS). Paratypes: 1 Ƥ, idem, 20.IV.2004 ( CMNG); 69 3 and Ƥ, Nicaragua, Dept. Rivas, Chacocente, 1–10.IV.2006 (and several other dates), leg. Eric van den Berghe ( CMNG, CHAH and MCCI); 10 3 and Ƥ, Nicaragua, Dept. Rivas, Rancho Santana, 6–7.XII.2003, leg. van den Berghe ( CMNG and MCCI).

Description of holotype. Length 6.3 mm. Dorsal color uniform bronze, pubescent. Vertex narrow, 1/3 width of head, with punctiform sculpture. Frons with green reflection, covered by long white pubescence which is not pruinose. Clypeus broad, transverse, without transverse carina. Eyes large, elongated. Antennae long, serrate from antennomere 4. Pronotum elongated, wider anteriorly, with lateral margins slightly rounded, just sinuate at angles, which appear acute. Disc regularly pubescent, depressed at sides and with two shallow central depressions, one behind vertex and one before scutellum. Sculpture superficial forming indistinct striae. Premarginal carinula plainly evident, joining anterior angle, but interrupted in middle, forming two segments: the basal curved more than 1/3 the length of pronotum, bisecting basal angle, and the anterior straight parallel to lateral margin, longer than half the length of pronotum. Marginal carinae joined at base. Scutellum large, with large transverse carina. Elytra with apex rounded. Disc covered with white pubescence more concentrated and yellowish in the 4 (2+2) spots along suture: the first more elongated at 2/3 the length of disc, the second, triangular, at 4/5 the length. Ventral color bronze like dorsal, uniformly pubescent. Anterior claws bifid, median with external spur bifid and internal mucronate, posterior mucronate. Metatarsus long but shorter than metatibia, with first metatarsomere as long as sum of following three (1=2+3+4).

Description of paratypes. Length from 4.3 to 6.4 mm. Anterior prosternal lobe rounded, prosternal plate enlarged at apex and apical margin of last visible abdominal sterna rounded. Females are distinguishable by copper frons, all claws mucronate and metatarsomeres shorter. Aedeagus black, sclerotized, with median lobe serrate at sides and apex rounded (figure 16).

Etymology. This is one of the more common and less showy species in the Niehuis collection. For this reason, the name chosen refers to more humble people living in Middle Ages: the “servus glebae ” (from latin gleba = clod of earth).

Comments. A. glebae n. sp. is similar to A. exsapindi Vogt, 1949 described from Mexico. It differs from Vogt’s species by having the vertex more narrow, pronotum more elongate with anterior margin more advanced between the eyes, premarginal carinulae curved and elytral apex rounded and shorter.
