Nothing is known about the biology of Monomorium hannonis.

Identification

Bolton (1987) - A member of the M. setuliferum species group. A very conspicuous and easily recognized member of the group, hannonis is isolated by its combination of dense blanketing reticulate-punctate sculpture and numerous standing hairs on all dorsal surfaces of the body. In other species of the group either hairs are absent from the cephalic dorsum, alitrunk and first gastral tergite in front of the apical transverse row (Monomorium alamarum, Monomorium ebangaense, Monomorium notulum, Monomorium setuliferum) , or sculpture is feeble to absent on the head and alitrunk dorsum (Monomorium havilandi, Monomorium macrops, Monomorium xanthognathum).

Description

Worker

Bolton (1987) - TL 2.7-2.8, HL 0.68-0.70, HW 0.60-0.61, CI 86-90, SL 0.52-0.53, SI 85-88, PW 0.39-0.40, AL 0.76-0.78 (3 measured).

Head short and broad (CI, above), the eyes distinctly in front of the midlength of the sides. Maximum diameter of eye 0.22-0.23 x HW, with 8-9 ommatidia in the longest row. Eyes weakly reniform in profile, the anterior angles of the eyes drawn out anteroventrally into a lobe. Metanotal groove shallowly impressed , the propodeum rounding broadly and evenly into the declivity. Postpetiole very swollen in profile, dome-lie and conspicuously much more voluminous than the petiole. In dorsal view the postpetiole more than twice the area of the petiole node but both segments broader than long. All dorsal surfaces of head and body with numerous standing hairs, the hairs subdecumbent on the first gastral tergite but erect to suberect elsewhere. Several pairs of hairs present on the propodeal dorsum. Occipital margin with projecting hairs across the width and on the curve of the occipital corners in full-face view, but none on sides of head where only short appressed pubescence is present. All surfaces of head, alitrunk, petiole, postpetiole and basal third of the first gastral tergite very densely reticulate-punctate, the sculpture sharply defined. Punctures fading out to superficial reticulation posteriorly on the first gastral tergite. Colour brown, the gaster slightly darker in shade than the head and alitrunk.

Type Material

Bolton (1987) - Syntype workers, Congo: Brazzaville (A. Weiss) (Naturhistorisches Museum, Basel; Musee Royal de I' Afrique Centrale) [examined].
