Longino & Fernández (2007) - Wasmannia rochai occurs widely in the mainland Neotropics. The syntype workers from Ceara are slightly larger than workers from Panama and Costa Rica, but with similar proportions. This species appears to be rare in Costa Rica, although its superficial similarity to Wasmannia auropunctata may result in its being overlooked in a sea of the latter species. Only two Costa Rican collections are known: Phil Ward collected workers and a dealate queen (PSW # 7628) in a recent treefall at Carara Biological Reserve. The senior author collected a lone dealate queen in a canopy tree at Sirena in Corcovado National Park. The species has been collected multiple times on Barro Colorado Island in Panama, where it is a relatively common part of the canopy ant fauna (Mike Kaspari pers. comm.).

Cuezzo et al. (2015) - The main characters to easily recognize workers of W. rochai, and separate this species from other of Wasmannia, are the presence of curved and clavate hairs on the dorsum of the mesosoma, short propodeal spines with a wide base, and a strong and well developed spine in the anteroventral part of the petiole.
Longino & Fernández (2007) - The differences between rochai and Wasmannia sigmoidea are subtle but consistent. Compared to sigmoidea , rochai is smaller, with a relatively shorter and broader head. The propodeal spines are shorter and are directed posteriorly, instead of upturned in sigmoidea . The setae on the face, mesosoma, and gaster are more curved, appearing shorter than the setae of sigmoidea because of the greater curvature. They are also more clavate, swelling noticeably at the tips. In some specimens of rochai the outer margin of the antennal scrobe is weakly defined, approaching the condition seen in Wasmannia affinis and Wasmannia lutzi. However, the face sculpture of rochai is always much more feeble than the coarse reticulate rugose sculpture on affinis and lutzi.
Keys including this Species
Longino & Fernández (2007): Kempf (1972) recorded the range of rochai as Panama, the Guianas, Trinidad, and six Brazilian states from Ceara south to Sao Paulo. Given the prior uncertainty of species differences among affinis , lutzi , rochai, and sigmoidea, earlier determinations should be treated cautiously pending reexamination of existing material. We have examined material from Guatemala, Costa Rica, Venezuela, and Brazil (Amazonas, Bahia, Ceara, and Sao Paulo states).
Cuezzo et al. (2015) - This species has been recorded from Costa Rica to São Paulo State, Brazil (Longino & Fernández, 2007). We extend its distribution north to Mexico and south to the seccional Yacuí (25º41´S, 54º26´W, 243m) of the Parque Nacional Iguazú, Misiones, Argentina.

Cuezzo et al. (2015) - In Argentina, this species co-occurred with Wasmannia longiseta in a secondary rainy subtropical forest belonging to the Paranaense phytogeographical province (Atlantic Forest ecoregion). This species is not as behavioral aggressive as Wasmannia auropunctata but is considered as a pest, particularly in the cocoa plantations of the southeast and southwest regions of Bahia State, Brazil (Souza et al., 2009).
Koch et al. (2018) sampled this species in Caryocar barsiliense trees, in southeastern Brazil cerrado, as part of a study examining species interactions in ant-plants.
Males have yet to be collected.
