Megalomyrmex incisus M.R. Smith, 1947

With the help of J. Lattke and E. Cancello I collected a colony of M. incisus in a dead twig on the ground in Caripe, Monagas province, Venezuela (10°10’N, 63°34’W) , in a very wet afternoon (October 30, 1986). Only adult ants occupied the small chamber under the bark of the twig. The sample includes one dealated female (undescribed) and 28 workers. From the IHVL, I studied a worker from Caquetá Salzano, Colombia .

From the MCZ, I studied a sample of M. incisus including one dealate gyne and seven workers collected at Windblow Ridge, Arima Valley, Trinidad (elevation 1800’) T-40, in May 15, 1988, collected by S. Cover and M. Moffett, “ 44 miles past end of Cooker Trace; secondary montane rainforest, about 20 years old, in rotten branch on forest floor”. S. Cover already compared the workers with the paratypes of M. incisus M.R. Smith in the MCZ (S. Cover det. 1990), with which I concur.

Gyne (first description)

Three equally developed ocelli; mesonotum with parapsidal sutures but no notaulus; katepisternum smooth; propodeum dorsal face and declivity continuous, with only one rugosity over the foramen; petiole ventral face with an anterior denticle, otherwise smooth; the postpetiole posterodorsal face has one continuous rugosity just before the socket, although rugosities are absent from the ventral face.
