Distribution. Madagascar. So far endemic to the Makay massif.
Note. This is an undescribed species, rather large for the genus, and very close to another undescribed species which lives in the Isalo massif.
Habitat in study area (Fig. 2F, N). Similar to Pachynectessp. Ma1 (with which it was syntopic at all sites), but this species is rarer.
