Anochetus haytianus

Known only from eastern Haiti. The types were collected from small colonies under rocks in shady places. Brown (1978) believed they are likely to be nocturnal foragers.

Identification
Summarized from Brown (1978): Distinguished from other emarginatus group species by its shorter mandibles (MI < 67) with fewer teeth and denticles along the inner preapical margins. More or less yellow in color. Distinguished from the similar Anochetus longispinus by its acute petiole teeth that are < .01 mm long.

Nomenclature

 *  haytianus. Anochetus (Stenomyrmex) haytianus Wheeler, W.M. & Mann, 1914: 15, fig. 6 (w.) HAITI. See also: Brown, 1978c: 611.

Worker
Length 6.5-7.5 mm.

Differing from emarginatus Fabr. in the following structural characters: The head is much broader behind, the mandibles shorter, with fewer (4 to 5) denticles on their inner borders and slightly shorter apical teeth. The antennal scapes and all the funicular joints are distinctly shorter, the former extending less than one quarter their length beyond the posterior corners of the head. The epinotum is quite unarmed, low and rounded in profile. The petiole is more erect, with subequal anterior and posterior declivities and at the summit with two teeth which are longer, more acute and more diverging than in emarginatus. Body smooth and shining; pronotum finely and longitudinally, meso- and epinotum more coarsely and transversely rugose; front of head also finely longitudinally rugose, the rugae diverging posteriorly. Hairs very sparse as in emarginatus and confined to the mouth and gaster.

Color brownish yellow, legs, mandibles and antennae paler, the tint throughout being lighter than in emarginatus subsp. testaceus Forel.

Described from a number of specimens taken at Manneville and in the mountains north of Jacmel from small colonies nesting under stones in shady places.
