Identification
Eye broadly convex, occupying approximately one-fourth of the lateral cephalic margin with head in frontal view; mesosoma slender with strong constriction at metanotal sulcus; mesonotum longer than wide; anterior carina of mesopleuron projects laterally as small hooked fin; petiolar node elongate with long anterodorsal margin in lateral view.
Worker metrics (n=2). HL 1.42 (1.31-1.38); HW 0.91 (0.88-0.88); ML 0.81 (0.78-0.81); EL 0.30 (0.27-0.30); SL 2.16 (1.99-2.09); WL 2.90 (2.86-2.90) mm. CI 0.64 (0.63-0.67); MI 0.89 (0.88-0.92); OI 0.33 (0.31-0.35); SI 2.37 (2.27-2.38).
Natural History
Occurs in wet forest.
Comments
This morphospecies is different from other species of the famelica group because of the elongate mesonotum and petiolar node, well-developed anterior mesopleural process, and the marked constriction of the mesosoma in lateral view, making it look like a slender hour glass. The only other famelica group member in Costa Rica is L. famelica, a much larger species.
