Ovatametra obesa Kenaga, 1942

New record. Colombia: Sucre: Toluviejo: Pechilín Stream, station 2 (09°26′08″ N, 075°26′15″ W), Wendy Molina-J., 15.VIII.2015 (WMJ 052).

Identification. The taxonomy of Ovatametra is very coarse, because it was never revised and some species are distinguished in the literature based almost entirely on the color pattern, which is quite variable when a large population is sampled. To aid in the identification of our material, we compared it with photos of type or reference material of all described species of the genus. The females examined agree well with O. obesa , with body length around 3.0 mm and abdominal mediotergite VII with a tuft of setae near the middle of the posterior margin ( Kenaga 1942). The pattern of dark stripes on the mesonotum, however, showed to be variable. Some specimens have the longitudinal dark stripes continuous along the segment and transversely connected on the anterior and posterior margins, whereas others have narrower, interrupted longitudinal stripes that do not connect anteriorly and posteriorly. The same type of variation was observed by FFFM in large populations from the Brazilian Amazon.
