Taxonomic History (provided by Barry Bolton, 2013)
Costa Rica: Atlantic and southern Pacific lowlands.
This species inhabits lowland wet to moist forest leaf litter. It is most often encountered in Winkler and Berlese samples. Workers were once collected at a honey/oil bait on the forest floor. Its frequency in Berlese samples suggests it is largely subterranean.

Taxonomic Treatment (provided by Plazi)
Wilson, E. O.:
etymology Gr beloceps , arrow-headed, referring to the elongate and vertically thin head capsule.
diagnosis A small, yellow species whose major has an elongated head, the dorsal surface of which, with the exception of the midclypeus and frontal triangle, is completely foveolate and opaque; the rest of the cephalic sculpturing comprising longitudinal carinulae confined to the anterior half of the capsule; antennal scrobe absent; thick long, vertical propodeal spines are present, thin tips turning slightly forward in side view; small, subangulate mesonotal convexity present, and postpetiolar node conulate. Similar to charazana , longinoi , neolongiceps , and prolixa , but differing from each in various combinations of the above traits, and other traits, as illustrated.
