Tetramorium miserabile

The one non-type record of T. miserabile was collected from the trunk of Acacia xanthophloeum in an Acacia woodland.

Identification
Bolton (1980) - Of the known species related to T. miserabile, Tetramorium luteipes has the mandibles finely longitudinally striate, Tetramorium gegaimi has the promesonotal dorsum sculptured with a disorganized ruguloreticulum, and Tetramorium browni has the pilosity of the alitrunk different from that of T. miserabile, as indicated in the discussion of that species.

Distribution based on Regional Taxon Lists
Afrotropical Region: Kenya, United Republic of Tanzania.

Nomenclature

 *  miserabile. Tetramorium miserabilis Santschi, 1918c: 153 (w.) KENYA. See also: Bolton, 1980: 342.

Worker
Bolton (1980) - TL 3.1, HL 0.75, HW 0.68, CI 91, SL 0.54, SI 79, PW 0.46, AL 0.82.

Mandibles mostly smooth but with some faint marks between the pits. Median clypeal impression weakly developed. Frontal carinae quite strong, distinctly more robust than any of the cephalic sculpturation, extending back well beyond the level of the eyes but petering out on the occiput. Maximum diameter of eye 0.14, about 0.21 x HW. Occipital margin of head broadly but quite shallowly concave, the sides of the head narrowly but evenly convex. Dorsal alitrunk evenly convex in profile, the propodeal spines straight and acute. Metapleural lobes triangular and acute. Petiole in profile as shown in Fig. 116, in dorsal view subglobular, slightly broader than long, the dorsum rounding into the sides and the anterior and posterior faces. Dorsum of head feebly longitudinally rugulose, the spaces between the low, weak rugulae filled with a fairly conspicuous superficial sculpture of shagreening or punctulation. Promesonotum with only feebly defined rugulose sculpture, predominantly longitudinal in direction but low and weak, the spaces between rugulae sculptured as the head; propodeal dorsum with stronger rugulose sculpture. Petiole, postpetiole and gaster unsculptured. All dorsal surfaces of head and body with numerous quite short, blunt hairs but the scapes and hind tibiae only with fine decumbent or appressed short pubescence. Colour a uniform pale brownish yellow, the appendages slightly lighter than the body.
