Major worker, lateral view (small image, large image), face view (small image, large image).
Range
Costa Rica, Venezuela. Costa Rica: Atlantic coast.
Identification
Antennae 9-segmented, so small it is hard to count the five segments between the two-segmented club and the larger first funicular segment; mesosoma relatively elongate; propodeal suture impressed; propodeum with separate dorsal face rounding into posterior face; petiole with distinct acicular anteroventral tooth.
Natural History
I know this species from two collections:
Costa Rica, Prov. Limon, 25km NW Cahuita: coconut strand along beach edge; nest under debris (dead wood or old coconut husk) on ground. This collection contained major workers.
Venezuela, Barinas State, 17km SW Cd. Bolivia (Ticoporo forest reserve), 240m: dense second growth with few larger trees; ex sifted leaf litter (Winkler sample).
Comments
This species is in Fern‡ndez's C. lignata complex. However, there is no key and it is difficult to place it with respect to Fern‡ndez's species.
