DaRocha et al. (2015) studied the diversity of ants found in bromeliads of a single large tree of Erythrina, a common cocoa shade tree, at an agricultural research center in Ilhéus, Brazil. Forty-seven species of ants were found in 36 of 52 the bromeliads examined. Bromeliads with suspended soil and those that were larger had higher ant diversity. Platythyrea sinuata was found in a bromeliad but was associated with twigs and bark cavities, rather than the suspended soil or litter, of the plant.

Silva-Rocha et al. (2017) - Platythyrea sinuata exhibits a great morphological similarity with Platythyrea angusta, Platythyrea pilosula and Platythyrea punctata making its correct identification difficult (Brown, 1975).

Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.


Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.



Silva-Rocha et al. (2017) collected individuals from a colony found in a cabruca area (cocoa plantation in native forest understory), between a rotted trunk and soil in Ilhéus, Brazil (14°47’51”S, 39°02’13”W). Karyotype anlysis revealed this species had 2n=44 chromosomes, with karyotypic formula 2k=24M+20A.
