Specimen Label


T. pallipes is a common and very widely distributed species in the Afrotropical and Malagasy regions, and is present as an introduction on the Atlantic islands off Africa. It has also been recorded from hothouses, and once from a dwelling, in the West Palaearctic. Nest sites appear opportunistic, being constructed in the ground under stones, in or under rotten wood, under the bark of living trees, in rotten parts of standing trees and in hollow stems and twigs of plants. The species efficiently colonises areas disturbed by human activities and may be prevalent in plantations of tree and shrub crops. In Madagascar it is common in parks and gardens and in South Africa it is known to invade houses, where it may nest in bizarre locations such as electricity transformers or light fixtures. In other countries it has been recorded as entering houses in search of sugary food or water. Foraging is carried out both terrestrially and arboreally. When foraging on shrubs and trees pallipes tends a wide range of homopterous insects. The species called albipes in Samways, Nell & Prins (1982), associated with outbreaks of red scale on citrus in South Africa, is most probably pallipes, as also is the species referred to as albipes by Prins, Robertson & Prins (1990) In their synopsis of pest ants of South Africa. (Bolton 2007)


Bolton (2007) - A member of the T. pallipes complex in the Technomyrmex albipes group. The arrangement of setae and their relative lengths is characteristic of this small but relatively large-eyed species. A similar arrangement is seen only in the closely related Technomyrmex vapidus of Kenya and Tanzama, but that species is larger, brightly coloured, and has more posteriorly located eyes.

A series of intercastes is present between worker and queen in which 0, 1 or 3 ocelli are developed and the mesosoma gradually increases in size and complexity. The mesonotum gradually differentiates into mesoscutum and mesoscutellum and in larger individuals a small prominent metanotum is also developed. Ergatoid males are produced as well as alate males and queens.

Keys including this Species


This species is of Afrotropical origin and has been introduced to the Palaearctic, Nearctic, Indo-Malayan and Australian regions (Bolton, 2007; Guénard et al., 2017). In the Canary Islands, it has reported for just one single locality of Gran Canaria (Hernandez-Teixidor et al., 2020).

In its introduced range, this species is found in greenhouses and houses (Wetterer, Espadaler, Wetterer, Aguin-Pombo, & Franquinho-Aguiar, 2007), but it is also common in outdoor areas such as parks and gardens in warmer countries (Bolton, 2007). Moreover, it has been reported as an occasional locally serious pest in citrus orchards (Bolton, 2007; Samways, Nel, & Prins, 1982). Although no major negative impacts have been reported to date, it could act as invasive such as other species of this genus like T. albipes (Hernandez-Teixidor et al., 2020).

Bolton (2007) - TL 2.3 - 2.8, HL 0.52 - 0.68, HW 0.46 - 0.64, SL 0.45 - 0.64, PW 0.33 - 0.37, WL 0.65 - 0.72 (30 measured). Indices: CI 84 - 94, SI 92 - 106, or 28 - 33, EPI 55 - 71, DTI 120 - 128.

Frontal carina with 2 setae: in profile the anterior above the torulus, the posterior at the level of the anterior portion of the eye; both of these shorter than the maximum diameter of the eye. No seta present at level of posterior margin of eye. Posterior to this the dorsum with 2 pairs of inconspicuous, extremely short stubbly setae, both of which are less than half the length of the seta above the eye: anterior pair about midway between level of posterior margin of eye and posterior margin of head, posterior pair very close to or at the posterior margin (easily abraded). In full-face view median portion of anterior c1ypeal margin extremely shallowly concave or feebly indented; posterior margin of head at most very slightly concave or impressed medially, sometimes almost transverse. Eyes relatively large and located in front of midlength, EPI < 80; in full-face view outer margins of eyes touch, or more usually break, the outline of the sides. Number of setal pairs on dorsal mesosoma: pronotum 1 - 3, shorter than maximum diameter of eye; mesonotum 1, about half the length of the pronotal setae and located at the point where the slope of the mesonotal dorsum changes; propodeal dorsum 0; lateral margins of propodeal declivity 2 (rarely 3), above the level of the spiracle. With mesosoma in profile the posterior one-third of the mesonotum is more steeply sloped than the anterior two-thirds. Metanotal groove distinct but only shallowly impressed. Dorsum of propodeum short and more or less flat, meeting the steeply sloped declivity in a blunted angle. Gastral tergites 1 - 4 each with numerous setae, distributed everywhere on the sclerites; usually all are distinctly shorter than the maximum diameter of the eye. Head, mesosoma and gaster uniformly light brown to uniformly black, with all shades attested between these extremes; sometimes the gaster is slightly darker than the mesosoma. Legs lighter than head and body, varying from pale yellow to dull brownish yellow. Tibiae and tarsi are always the same colour, the former never considerably darker than the latter; femora may be somewhat darker, in whole or in part, than the tibiae.
