Synonyms | |
|
Temnothorax andrei occurs in relatively dry coniferous forests, oak woodland, laurel forest, pinyon-juniper and cool deserts. Nests are small, usually less than 100 workers, and found under stones or in loose layers of large stones. Colonies have also been found living within Camponotus and Formica nests.
Identification
Prebus 2017 - A member of the andrei clade.
Mackay (2000) - This is a small, light yellow or brown species with a 12 segmented antenna; striae are on head, except for a narrow central strip which is smooth and shining, entire mesosoma, petiole and postpetiole are punctate. The clypeus has a number of poorly defined carinae, the medial carina is poorly developed. The subpeduncular tooth is well developed, the petiolar node is blunt and rounded in profile, gaster entirely smooth and shining. The propodeal spines consist of small angles. The postpetiole is not broadened. The hairs on the petiole and postpetiole are somewhat clavate.
Although similar to the following species, differs in that the node of the petiole is not broadly rounded. It would be easily separated from Temnothorax bestelmeyeri by the smaller eyes, from Temnothorax terrigena in that the head has striae (not punctate) and from Temnothorax furunculus by the very different sculpture of the clypeus (numerous, poorly developed carinae instead of a single medial carina and 2 prominent lateral carinae). Specimens from Arizona (Cochise Co.) are roughly sculptured, having poorly defined rugae on head, mesosoma and top of petiole and may represent an undescribed species.
Ward (2005): In coastal regions of central and northern California populations of T. andrei tend to produce workers that are darker in color, with a shinier head and better developed propodeal spines.

Countries Occupied
Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species. |
Estimated Abundance
Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species. |
Habitat
Dryer habitats including oak woodland, dry coniferous forest, laurel forest, pinyon-juniper, and cool desert (summarized by Mackay 2000).
Abundance
Common.
Biology
Colony Attributes
Cole (1958) found colonies contained from 32 to 109 workers but, based on the collection information included in his account of Temnothorax andrei, this is based on a small number of samples.
Nesting Habits
Nests are found under stones or in interstitial spaces between rocks (Wheeler and Wheeler, 1973, 1986; Cole 1958, Mackay. pers. obs.).

Other Ants
This species occasionally lives in nests of Camponotus yogi (as a xenobiont, found in chaparral, in living stems of Haplopappus pinifolius; Creighton & Snelling, 1966; Kanizsai et al., 2013) as well as with other Camponotus and Formica (Creighton and Snelling, 1966), including Formica moki (Mann, 1911) and the thatched nests of Formica ravida (Mackay & Mackay, 1984).
