Aphaenogaster famelica erabu Nishizono & Yamane, 1990; Watanabe & Yamane, 1992
|
Description
|
|
Very similar to A. famelica in body shape and sculpture. A. erabu is, however, consistently distinguished from famelica by its yellowish brown body color, shorter propodeal spines, and lower chromosome number (2n=32 vs. 2n=34).
|
Remarks
|
|
The population on Kuroshima I. is undoubtedly closely related to the others listed above, but there is some uncertainty concerning its relative taxonomic status. A. erabu nests underground in forests. Workers turn their gasters downwards while foraging.
