Nothing is known about the biology of Temnothorax ruginosus.

Identification

Zhou et al. (2010) - This new species resembles Temnothorax basara but differs from the latter by petiolar node shape and sculpture on dorsum of head. It differs from Temnothorax zhejiangensis by dorsum of head and mesosoma with distinct longitudinal rugosities, the spaces between rugosities smooth.

Description

Worker

Holotype. HL 0.66, HW 0.56, SL 0.53, PW 0.42, ML 1.84, PL 0.30, PH 0.22, ESL 0.20. Paratypes. HL 0.64-0.66, HW 0.52-0.56, SL 0.50-0.53, PW 0.38-0.42, ML 1.80-1.82, PL 0.26-0.30, PH 0.18-0.22. ESL 0.17-0.20 (5 specimens measured).

Head longer than broad (CI = 1.18-1.23), with convex sides, slightly convex occipital margin and rounded occipital corners. Anterior clypeal margin broadly rounded. Antennae 12-segmented, antennal scape relatively long, almost reaching occipital margin (SI1 = 0.78.0.80, S12 = 0.94-0.98).

Mesosoma with slightly convex dorsum, without metanotal groove. Propodeum with very long, slightly down-curved, sharp spines that are not widened basally (ESLI = 0.32-0.35). Humeri in dorsal view broadly rounded. Petiole distinctly longer than high (PI= 1.36-1.56), with distinct anterior peduncle; petiolar node in profile with almost straight or slightly concave anterior face and narrowly rounded dorsum. Postpetiole as high as petiole, subglobular.

Dorsum of head with coarse longitudinal rugosities, sides with coarse reticulations. Mesosoma with coarse sinuous longitudinal rugulosities, sides of pronotum, petiole and postpetiole densely punctuate.

Occipital margin and dorsum of mesosoma with long, thin, slightly curved standing hairs, which are longer than the maximum eye diameter. Whole body concolorous ochreous-yellow.

Type Material

Holotype worker, China: Jiangyong County, Hunan Province, 18 September, 2004 (Jianhua Huang). Paratypes 12 workers, data as holotype.

Etymology

This species is named after the characteristic form of the sculpture on dorsum of head.
