Microcambeva barbata

Costa and Bockmann 1994







Holotype: MZUSP 43678 26-1 mm.

Paratypes: MZUSP 43679 21.4 mm SL, UFRJ 684 (2) 21.6 and 23-8 mm SL.


Known only from the type locality: Estado do Rio de Janeiro, rio So Joo, near Gavires, Municipio de Silva Jardim, Brazil

The distribution, within South America, of the subfamilies Sarcoglanidinae and Glanapteryginae and the subfamily Microcambevinae and completetly disjuct. The first two subfamilies are found throughout Amazonia whereas the third subfamily is found only in the Atlantic Forest of eastern South America (Costa, Henschel and Katz 2020 Figure 5).


Interstitial (psammophilic).


Costa, Henschel and Katz (2020) determined that the genus Microcambeva is not a memder the subfamily Sarcoglanidinae as has been supposed for some time. They created the new subfamily Microcambevinae for Microcambeva and Listura. The genus Listrura is not included on this website as its species live in leaf litter, rather than sand, and so are not interstitial (or psammophilic) species.

Biological Notes
