Diagnosis

This species is recognised by the following characteristics: Head subtrapezoidal with angulated occipital corners; frontal lobes markedly expanded laterally and anteriorly, projecting over the clypeus and part of the mandibles; antennal scrobes deep, completely covered by lateral expansions of frontal lobes; promesonotum continuously rounded in profile; metanotal groove wide and shallow; propodeal spines short and acute; tegument hard with sculpture and coarse pilosity ( Feitosa et al. 2008) (Fig. 14 View Figure 14 ).

Distribution

Stegomyrmex manni is a Neotropical species widely distributed in Mesoamerica, but with scarce records in South America ( Feitosa et al. 2008). This is the first report of the species in Caquetá and the second report of this species in the country ( Serna 2002), marking the first record of the species for the Amazon rainforest region. In the Neotropical Region, the species has also been recorded in Ecuador, French Guiana, Honduras, Nicaragua, Costa Rica and Panama ( Smith 1946, Kempf 1972, Ryder et al. 2010 b, Franco et al. 2019).

Biology

The specimen was collected using the TSBF methodology, between 0 and 10 cm depth, which would suggest that this species inhabits the soil. This record complements the observations made by Feitosa et al. (2008), where they mentioned that S. manni is a soil inhabitant and is collected infrequently using Winkler bags. Here, we report, for the first time, the hypogeic habits in this species.
