( Figure 3 A-D)

Trigona (Trigona) dimidiata venezuelana Schwarz, 1948: 291 [original description]; Camargo et al. 2013 [catalog, geographic destribution].

Trigona (Trigona) venezuelana : Almeida, 1984: 141, 142 [comparative notes].

Diagnosis: This species is similar to T. (D.) dimidiata in the wing membrane and infuscate veins in the basal half, sub-marginal cell whitish. But differs from other species of the subgenus mainly in the half of the supraclypeal area below the antennal cavities more or less hairy, like the half extending above the antennal cavities. total body length approximately 6 to 7, 5 mm.

Geographic distribution: Venezuela (Aragua, Distrito Federal, Yaracuy).

Examined type-material: One worker (holotype) was examined through of digital image. Lagunita de Aroa Venez / Altitude 2000 ft / MACarriker collector / HOLOTYPE / Trigona (Trigona) dimidiata . var. venezuelana H.F. Schwarz / Type No 61571 USNM / USNM ENT 00534531 .

Comments: This species was described by Schwarz (1948) based on workers specimens, all from Venezuela. Although Schwarz (1948) indicated that the paratypes are in the British Museum (Natural History) and the American Museum of Natural History, he does not mention the numbers of paratypes in each collection. T. (D.) venezuelana is similar to T. (D.) dimidiata mainly in relation to the size of the body and wing membrane (wing membranes and veins infuscate in the basal half, sub-marginal cell whitish), however, differs from T. (D.) dimidiata and T. (D.) sesquipedalis by half of the supraclypeus below the antennal cavities more or less hairy, like the half extending above the antennal cavities
