Anochetus longispinus

Known from the northeastern foothills of the Massif de La Hotte on the southwestern peninsula of Haiti at an elevation of about 1000 m or more.

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 haytianus by its slender petiole teeth that are more than 0.25 mm long.

Distribution based on Regional Taxon Lists
Neotropical Region: Greater Antilles, Haiti.

Nomenclature

 *  longispinus. Anochetus (Stenomyrmex) haytianus subsp. longispina Wheeler, W.M. 1936b: 196 (w.) HAITI. Raised to species: Brown, 1978c: 611.

Worker
Differing from the typical haytianus in having the head slightly narrower behind, with distinctly longer and more slender antennal scapes and funiculi, and in the greater length of the petiolar spines, which are fully twice as long as those of haytianus. The coloration is also different, the head and thorax being darker and distinctly red as are also the tibiae. The transverse striation of the thorax, especially in the epinotal region, is distinctly coarser, the middle of the pronotum smoother and more shining.



Type Locality
Six specimens taken by Dr. Darlington in the northeastern foot-hills of the Massif de la Hotte, Haiti, 3000-4000 ft. (Wheeler's reported elevation is different from the label on the cotypes in the MCZ, as is shown to the right).
