Specimen labels


Camponotus lubbocki commonly occurs in montane shrubland and montane rainforests in the northeast, central, and southern high plateau of Madagascar. The species is rarely known from rainforests and the transitional forest between spiny and dry forests. Across this mountainous region, the species nests mostly in the ground, in root mats in the ground, and under moss on the ground, but occasionally nests in rotten logs and under stones. (Rakotonirina & Fisher, 2018)


In full-face view, lateral margin of head anterior to eye level diverging posteriorly; anterior clypeal margin truncate; no white spot on dorsum of second and third abdominal tergites; body color black; antennal scape without erect hairs, propodeal dorsum slightly concave. (Rakotonirina & Fisher, 2022)

Camponotus lubbocki might be confused with Camponotus liandia but the latter has a broadly convex anteromedian margin of the clypeus. It looks similar to Camponotus immaculatus and Camponotus kelimaso because they too lack white spots on the second and third abdominal segments, but in C. immaculatus the propodeal dorsum is transversely concave and in C. kelimaso the eyes are small and the posterior cephalic margin is approximately straight.

Forel (1912) originally placed C. lubbocki under the subgenus Myrmosaga, which was later synonymized by Emery (1925) under Mayria (see also Rakotonirina and Fisher 2018). Whereas this species was recently redescribed under Mayria, it is morphologically similar to those within Myrmosaga because of its broadly projected rectangular clypeus that is medially carinate, and a more or less anteroposteriorly flattened petiolar node. The subgenus Mayria is characterized by the clypeus that has no median carina, but with a rounded anterior margin, and a nodiform petiole. Therefore, C. lubbocki was moved back to the subgenus Myrmosaga by Rakotonirina & Fisher (2022).

Rakotonirina and Fisher (2018) - Minor. In full-face view, head elongate and rectangular, posterolateral margin rounding to the roughly straight posterior margin. Clypeus with broadly rounded anterior margin and remarkable anterolateral angles; median carina visible and fully developed. Eyes not breaking lateral outlines of head, their posterior margins located far behind the midlength of the head (PoOc/CL: 0.27±0.01; 0.25–0.30). Mandible triangular, apical margin with six sharp teeth. Antennal scape long, its basal half nearly reaching posterior cephalic border. In lateral view, pronotum and anterior portion of mesonotum noticeably convex; posterior portion of mesonotum and propodeal dorsum straight; junction of propodeal dorsum and declivity surface broadly angulate; propodeal dorsum roughly three times longer than height of declivity; propodeal spiracle slit-like. Petiolar node higher than long and tapering dorsally.

Sparse, erect hairs, shorter than height of propodeal declivity and abundant, long pubescence present on dorsum of head, mesosoma, petiole and gaster; body color entirely reddish-black to black.

Major. With characteristics of minor worker, except for the following characters: enlarged head, with slight medial excision on posterior margin; medially concave anterior clypeal margin; apical third of antennal scape surpassing posterior cephalic margin; pronotum and mesonotum forming an even convexity and separated from propodeum by distinct metanotum.
