Adelomyrmex silvestrii (Menozzi) View in CoL   HNS (Figs. 13-18, 32, 73)

Apsychomyrmex silvestrii Menozzi   HNS , 1931, 270 (w); Borgmeier, 1937:210; Smith, 1947:409. [Holotype not seen, presumably in Deutsches Entomologisches Institut].

Adelomyrmex silvestrii (Menozzi)   HNS : Kempf, 1972:18 ( New combination); Bolton, 1995:58.

Worker measurements (n=8). HL 0.56-0.57 HW 0.52 - 0.54 SL 0.36-0.38 EL 0.05 - 0.06 WL 0.50-0.55 GL 0.74-0.77 TL 2.30-2.35 CI 94 SI 71-72.

Worker diagnosis: Sides of head evenly convex. Mandibles with 5 teeth decreasing in size from the apical teeth. Basal margin of the mandible with the tooth feebly developed. Dorsum of clypeal plate with two curved ridges very closed, prolongued into frontal carinae. Eyes small, with less than 10 facets, most with 5-6 facets.. Hypostomal tooth small but clearly visible in frontal oblique view. Promesonotum slightly convex to flat, with strong transversal fringe on anterior pronotal margin. Metanotal groove weak. Propodeum sloping with two spines long, stout, directed backwards and nearly horizontal. Petiole stout in profile, with feebly concave posterior side, ventral face convex with several transverse rugae, appearing as serrations in profile. Postpetiole high, campaniform with a ventral transverse ridge toothlike as seen in profile. In dorsal view and lateral view, postpetiole extending posteriorly over basal gaster, as a blunt point. Gaster with emarginate base and humeral angles. Dorsal surface of head, pronotum and mesonotum with coarse, longitudinal rugulae. Transverse rugae between propodeal spines and sides of petiole and postpetiole. Declivity face of propodeum from smooth to covered with transverse rugae. Mandibles, clypeal plate, legs, petiole, postpetiole and gaster shining. Meso and hind tibia with some long hairs. Hairs yellowish, long and sparse (most hairs about 0125 mm long, as long as basal width of apical flagelomere), more short and apressed on antennae and legs. Body black to dark brown or dark reddish, antennae and legs more ligther, brown to yellowish.

Queen: Not measured.

Male: Unknown.
