Tetramorium inglebyi

One collection records states it was collected in evergreen forest and this is all that is known about the biology of this species.

Identification
Bolton (1977) - The closest relative of inglebyi is Tetramorium myops, also from India, but in this latter species the eyes are reduced to a single facet and the clypeus does not show the abrupt curvature which characterizes inglebyi. Other species in which the frontal carinae are very short, namely Tetramorium elisabethae, Tetramorium fergusoni, Tetramorium nursei and Tetramorium politum, may be separated by the characters given in the key.

Distribution
Reported from Borneo (Wang & Foster, 2016; Zryanin, 2011) and Yunnan, China (Xu, 1998; Qiao et al., 2009; Guenard & Dunn, 2012) but these are considered to be dubious by Agavekar et al. (2017) who treat this taxon as endemic to India.

Distribution based on Regional Taxon Lists

Worker
Bolton (1977) - TL 2.8, HL 0.74, HW 0.64, CI 86, SL 0.46, SI 72, PW 0.46, AL 0.76.

Clypeus very strongly down curved in its apical half so that the true median anterior border cannot be seen in full-face view. Frontal carinae very short, not extending to level of eyes, terminating just behind the expanded lobes over the antennal insertions. Antennal scrobes absent. Eyes small, maximum diameter c. 0.10 or about 0.16x HW. Propodeal spines short and stout, abruptly upcurved at the extreme apices. Metapleural lobes broadly triangular and acute, feebly upcurved. Petiole node in dorsal view approximately as long as broad, postpetiole subglobular, slightly broader than long. First gastral tergite in dorsal view with the anterolateral corners rounded and extended forwards to surround the articulation with the postpetiole, the margin of the tergite between the corners strongly concave. Dorsum of head with fine, predominantly longitudinal and somewhat uneven rugulation which grades into a reticulum posteriorly and on the sides. Dorsal alitrunk with sparse rugosity, the mesonotum predominantly unsculptured. Petiole and post petiole dorsally mostly unsculptured, with faint rugulation towards the sides; gaster unsculptured. All dorsal surfaces of head and body with numerous fine erect hairs. Colour uniform yellow-brown.
