Identification
Fernández (2004) - A member of the Carebara lignata species complex. C. panamensis is only known from a very small soldier/ergatoid (1.3 mm) and a tiny worker (0.90 mm) from Panamá (Wheeler 1925). The soldier exhibits characteristics that are apparently between those of female and soldier, with a single central ocellus. In the described soldier, the right eye is bigger than the left.
The worker corresponds to those typical of Carebara and neither the drawing nor the description is sufficient to separate it other American Carebara except for Carebara anophthalma, Carebara reticulata and Carebara elongata.

Description
Queen
Fernández (2004) - (provisionally asigned): HW 0.43; HL 0.55; SL 0.26; EL 0.08; PW 0.31; WL 0.78; GL 1.13; TL 2.98; CI 78; SI 60.
Head longer than wide, posterior border of head slightly concave. Sides of head slightly narrowed toward basal border. Mandible with 5 stout tooth. Three ocellae present, each in a concavity. Mesosoma in side view very similar to soldier/ergatoid of C. panamensis, although modified as myrmicine queens. Propodeum unarmed, narrowly rounded. Propodeal spiracle small, low, close to metapleural gland bullae. Subpetiolar process small. U-shaped trench in the basalmost portion of the first tergum. Body smooth and shining, head subopaque densely and longitudinally rugulose. Pronotum and most of mesonotum finely longitudinally striated. Short curved hairs densely over body, except propodeum, petiole and postpetiole. Hairs longer on clypeus, with a few on head, promesonotum, petiole, postpetiole and gaster. Color yellowish.
The described female is tentatively assigned to C. panamensis on the basis of size, geographical proximity, general configuration of the mesosoma, and head/ mesosomal sculpturing. Positive association of females with soldiers will be necessary to confirm whether they are actually conspecific.
