Specimen Label

Specimens have been collected from a litter sample in a upland woodland and from a hickory nut. The type series was reported to be from (Brown 1950) "a small colony-series taken in a pine woods near Landon, Mississippi."

Identification

Bolton (2000) - A member of the Strumigenys rostrata-group. In general appearance bunki is very similar to Strumigenys creightoni (see the species identification section of creightoni for more discussion of comparative features) of the pulchella-group, and the two have frequently been found confused in collections. The diastema is always long (distinctly longer than basal tooth length) in creightoni, and the basal row of teeth numbers 4; of these the second tooth from the base is longer than the third. In bunki the diastema is shorter than the length of the basal tooth and there are 5 principal teeth in the basal mandibular row, of which the third tooth from the base is the longest, distinctly longer than the second.

Description

Worker

Bolton (2000) - TL 2.0-2.2, HL 0.54-0.59, HW 0.37-0.39, CI 64-69, ML 0.09-0.11, MI 16-20, SL 0.26-0.29, SI 70-76, PW 0.24-0.26, AL 0.50-0.55 (10 measured).

Mandibles at full closure with a small basal gap; diastema shorter than length of basal tooth. Anterior clypeal margin transverse or its median section extremely feebly concave. Eye with 3-4 ommatidia in the longest row. Clypeal dorsum with small appressed spatulate to spoon-shaped hairs that are much smaller than those that fringe the lateral margins. Cephalic dorsum behind clypeus with larger broadly spatulate to spoon-shaped ground-pilosity, but entirely lacking finer more erect specialised hairs. Dorsolateral margin of head with a row of anteriorly curved spoon-shaped hairs , without freely projecting specialised hairs anywhere along the margin, without an apicoscrobal hair. Pronotal humeral hair varying from recurved and elongate-spatulate to almost filiform (this variation can be noted in a single series). Dorsal alitrunk with curved spatulate to spoon-shaped ground-pilosity but without simple standing hairs. First gastral tergite with fine flexuous to flagellate hairs. Hind basitarsus usually without flagellate hairs projecting from the dorsal (outer) surface, but occasionally a specimen with 1-2 such hairs present.
