Nothing is known about the biology of Camponotus humerus.

Identification

Wang and Wu (1994) – Similar to Camponotus vitiosus with the following differences: In C. humerus, pronotal angles with obtuse teeth; anterior border of pronotum margined; pronotum much broader than mesonotum and propodeum; color of head, alitrunk and petiole brownish red to brownish black. While in C. vitiosus, pronotal angles obsolete; anterior border of pronotum round, without a margin; pronotum slightly broader than mesonotum and propodeum; color of head, mesonotum, propodeum and petiole black or with a tint of brown.

Description

Worker

minor (Holotype cited first): TL 3.3, 4.0, 4.1; HL 0.81, 0.94, 0.96; HW 0.78, 0.89, 0. 90; HI 96, 94, 94; SL 0.80, 0.90, 0.82; SI 103, 101, 91; PW 0.66, 0.79, 0.78; ED 0.22, 0.22, 0.24; PI 85; 89, 87; WL 1.10, 1.04, 1.20.

Head slightly longer than broad. Sides of head and occipital border slightly convex. Clypeus convex, without medial crina. Anterior border transverse or slightly emarginate. Protonum very broad, 1.8-2.0 times of the length. Anterior border of pronotum margined. Pronotal angles forming two obtuse teeth, slightly pointed to the up of the pronotum. Meso-propodeal suture obsolete. Propodeum narrow. The posterior part of the base of propodeum declive. Declivity of the propodeum almost vertical. Petiole broad, cuneate, the apex transverse. Gaster broad and large.

Body shining. Punctures at front of the head minute and reticulated. Posterior part of the head more or less delicately wrinkled; Alitrunk and petiole delicately wrinkled. Gaster smooth.

Pilosity dilute. Pubescense can only be seen in certain light. Alitrunk and petiole each with 6 hairs. Pronotum without hairs. Mesonotum without hair or with 2 hairs. Head, alitrunk and petiole brownish red. Gaster black.

Variation: The worker collected in Jiangxi Province with the mesonotum, propodeum and gaster brownish black.
