Holotype worker.

Madagascar: Province Toamasina: RNI Betampona, 34.08 km 332° Toamasina, -17.91977, 49.20039, 525 m, rainforest, Malaise trap, 06 Apr 2008-01 Feb 2009 (B.L. Fisher et al.) collection code: BLF19594, specimen code: CASENT0145284 ( CAS).


3 minor workers with same data as holotype but specimen coded as: CASENT0138778, CASENT0138799, CASENT0138800 ( NHMUK, PBZT, CAS).

Additional material examined.

Madagascar: Antsiranana: Foret de Binara , 9.1 km 233° SW Daraina, -13.26333, 49.60333, 650-800 m, rainforest (B.L. Fisher et al.) ( CAS) GoogleMaps . Toamasina: RNI Betampona, 34.08 km 332° Toamasina , -17.91977, 49.20039, 525 m, rainforest (B.L. Fisher et al.) ( CAS) GoogleMaps .


With head in full-face view, lateral cephalic margins converging posteriorly towards eye level and covered with erect hairs; erect hairs lacking posterior to eye level; anteromedian margin of clypeus broadly convex; two apical teeth of mandible normally spaced.


Minor worker. In full-face view, head sides anterior to level of eye parallel; lateral cephalic margins posterior to level of eye converging progressively to posterior margin; eye large (EL/CS: 0.28 ± 0.01; 0.27-0.29), protruding, and breaking lateral cephalic border, level of posterior margin located at posterior 1/3 of head (PoOc/CL: 0.31 ± 0.02; 0.30-0.33); frontal carinae slightly diverging posteriorly (FR/CS: 0.25 ± 0.01; 0.24-0.26), larger than smallest distance to eye; clypeus with rounded anterolateral corner and broadly angulate anteromedian margin; mandible with two apical teeth distantly spaced; antennal scape relatively long (SL/CS: 1.95 ± 0.00; 1.95-1.96). Mesosoma low and long (MPH/ML: 0.30); dorsum of mesosoma more or less flat, promesonotum weakly convex, posterior portion of mesonotum flat immediately anterior to barely visible metanotal groove; propodeal dorsum anteriorly slightly convex and posteriorly flat, its junction with declivity bluntly angulate; propodeal dorsum 3 × as long as declivity. Petiole nodiform, with dorsal margin inclined posteriorly and forming a blunt angle to anterior margin; anterior face 1/2 height of posterior face, which inclines anteriorly to the dorsal face; femur of hind leg rounded axially, not twisted basally.

First and second gastral tergites without a pair of white spots; lateral margin of head anterior to level of eyes covered with erect hairs, which are lacking posterior to level of eyes; two erect hairs present near posterior cephalic margin; antennal scape covered with suberect hairs inclined at ca. 30° as well as appressed hairs; pronotum with a pair of erect hairs; posterodorsal angle of propodeum with a pair of erect hairs.

Major worker. Unknown.

Distribution and biology.

The distribution of C. tendryi is limited to Madagascar, in rainforest habitats of the RNI Betampona and RS Ambatovaky in the east, and the transitional humid forest of Binara in the northeast (Fig. 76D View Figure 76 ). Specimens have been collected foraging on lower vegetation, but the species nests in rotten logs.


See discussion under C. dufouri .

Camponotus tendryi were not included in the morphometric analysis due to the lack of sufficient minor worker samples.


The species name Camponotus tendryi is a Latin noun in the genitive case derived from the first name of a male person “Tendry”.
