Holotype Labels

Only known from the type locality in Phang-nga Province, Thailand.


Zettel et al. (2018) - Minor worker: Head and scape orange; mesosoma orange brown with variable light or medium brown areas dorsally, especially on propodeum. Vertex domed. Clypeus basally shallowly emarginated, with a hardly traceable median carina. Flagellum of normal length. Pronotum with reduced sculpture, somewhat shiny, with long standing setae. Dorsal outline of mesonotum and propodeum slightly convex, in some specimens separated by a weak depression.

Major worker unknown.

The minor worker of C. schulzianus is similar to Camponotus inquilinus by colour and sculpture, but differs by a more highly raised vertex, a slightly different outline of the clypeus, a slightly stouter mesosoma, a more structured dorsal outline of the mesosoma including a slight depression in front of the propodeum, reddish brown antennomeres that are increasingly infuscated towards apex, and reddish distal tarsomeres. The eyes are slightly smaller than in C. inquilinus (EI 31–32 vs. 33–35); in full-face view, they are laterally not fully reaching the head sides in two of four specimens.

Structures: Head roundish, dorsally reticulated and matt; laterally, ventrally, and on vertex with reduced microsculpture and shiny. Lateral outline of eye and head contiguous, or eye just not reaching head sides. Vertex moderately raised. Shiny midline of frons reduced. Clypeus with broad, but shallow emargination of basal margin; distal margin protruded in middle, laterally slightly concave; median impression in basal half indistinct. Mandible strongly punctate, with five teeth. Mesosoma moderately slender and low, reticulated and matt, except for shiny, unsculptured pronotum (except minute depressions of setae); dorsal outline of pronotum and posterior slope of propodeum moderately convex, with a weak indention between pro- and mesonotum, and with a shallow depression in front of propodeum. Petiole with stocky node, its anterior and posterior face almost parallel, apex strongly obliquely truncated. Gaster tergites with dense reticulation, absent only on very narrow marginal stripes (ca. 0.02 mm on tergites 1 and 2, slightly broader on tergites 3 and 4).

Pilosity: Entire dorsum with long whitish standing setae, longest on propodeum, petiole, and apex of gaster. Subdecumbent pubescence short, thin, whitish; very sparse on head.

Colour: Head reddish brown. Mandibles yellowish. Mesosoma of similar colour as head, but with some variable infuscated areas; part of propodeum blackish. Petiole dark brown to black. Gaster black. Scape orange yellow; funicular segment chiefly orange, increasingly infuscated towards apex. Legs black, tibia dark brown, tarsi apically reddish brown.
