Diagnosis.

Lateral cephalic margins approximately parallel in full-face view; two apical teeth of mandible normally spaced; antennal scape covered with suberect hairs inclined at ca. 30°; in lateral view, posterior 1/2 of mesonotum to posterodorsal corner of propodeum somewhat convex, propodeal dorsum ca. 2 × as long as the height of declivity surface; petiolar node flattened anteroposteriorly.

Description.

Minor worker. In full-face view, head sides anterior to level of eye parallel; lateral margins posterior to level of eye converging progressively to posterior margin; length of posterior portion of head behind eye level 1/3 length of head (PoOc/CL: 0.30 ± 0.01; 0.28-0.31). Eyes protruding and large (EL/CS: 0.30 ± 0.02; 0.27-0.33), breaking lateral cephalic margin. Frontal carinae not strongly diverging posteriorly (FR/CS: 0.28 ± 0.01; 0.26-0.30) and posteriorly parallel; clypeus with anterolateral angle and its anterior margin with medial blunt angle or convex. Mandible with six teeth, two apical teeth normally placed. Antennal scape relatively long (SL/CS: 1.55 ± 0.07; 1.40-1.73) with suberect hairs inclined 30°. Promesonotum weakly convex and mesopropodeum feebly convex (MPH/ML: 0.39 ± 0.02; 0.36-0.42), posterior portion of mesonotum flat immediately anterior to metanotal groove, metanotal groove weakly visible, propodeal dorsum anteriorly convex and posteriorly flat, junction of dorsal margin and declivity with blunt angle, propodeal dorsum 2 × as long as the declivity. Petiolar node flattened anteroposteriorly or short and high, its dorsal margin rounding to anterior margin. Tibia of hind leg rounded.

First and second gastral tergites without a pair of white spots. Erect hairs on lateral margin of head anterior to level of eyes present, but absent posterior to level of eyes; posterior margin of head with two pairs of erect hairs; posterodorsal angle of propodeum with a pair of erect hairs.

Major worker. Differing from minor worker in the following characters: enlarged head (CS: 2.92 ± 0.15; 2.62-3.10; CWb/CL: 0.93 ± 0.03; 0.90-0.99), in full-face view with slightly concave posterior margin, eye not breaking lateral cephalic margin; apical 1/4 of antennal scape surpassing posterior cephalic margin; robust mandibles and mesosoma, metanotum distinctly visible; petiolar node tapering dorsally.

Distribution and biology.

Camponotus mixtellus is a widespread species of the Malagasy region that occurs in the eastern lowland to montane rainforests and part of the western dry forests of Madagascar; it is known also from secondary rainforest and dry forest habitats of Grand Comore and Moheli of the Comoros islands (Fig. 67D ). As this species is both arboreal and terrestrial, its members are commonly found foraging on low vegetation and on the ground, and nest in dead branches and twigs above the ground, in rotten logs and rotting tree stumps, in the ground, or under stones.

Discussion.

Camponotus mixtellus can be confused with C. hovahovoides , but the latter has a longer propodeal dorsum that is ca. 3 × as long as the declivity. It looks similar to C. boivini but the latter is characterized by an antennal scape covered with suberect hairs inclined at ca. 45°.

The cluster of C. mixtellus shown by the NC-clustering method is confirmed by the cumulative LDA at 100% identification success, indicating support of the species hypothesized by qualitative morphology-based taxonomy.
