Paratrigona glabella Camargo & Moure, 1994

( Figs. 1–4 )

Description. Body length 4.5 mm, head length 1.56 mm, head width 1.63 mm, mesosoma width (intertegular distance) 1.16 mm, metasoma width (measured across T2) 1.67 mm. Color predominantly black, with yellow maculations on head and mesosoma ( Figs. 1–3 ), integument dull, finely and densely punctate. Head mixed ( Fig. 1 ). Right side: worker-like, mandible quadridentate, antenna normally developed with ten flagellomeres and scape long and slender (0.64 mm in length, 0.1 mm in width), alveolocular distance 0.24 mm, distance between lateral and median ocellus 0.1 mm, eye (in frontal view) 5.1 times longer than broad. Left side: male-like, mandible edentate longer than males, antenna with eleven flagellomeres and scape thicker and shorter than workers (0.5 mm in length, 0.12 mm in width), alveolocular distance 0.2 mm, distance between lateral and median ocellus 0.08 mm, eye (in frontal view) 3.5 times longer than broad. Mesosoma mixed ( Fig. 3 ). Right side: with worker features, including all right legs. Hind tibia 2.77 times longer than broad, corbicula normally developed, hind basitarsus about twice as long as broad with strongly projecting on posterodistal margin ( Fig. 4 ). Yellow spots are intensely colored. Left side: with male features, including all left legs. Hind tibia 3 times longer than broad, and without corbicular depression; hind basistarsus 2.8 times longer than broad without projection on posterodistal margin ( Fig. 2 ). Yellow spots more discolored and slender than in the worker. Metasoma symmetric, with features of workers. Genital structure developed as a normal reduced sting. Material examined: Argentina, Salta, Finca del Rey, 31–XI–1952, Coll. A. Ogloblin.
