Strumigenys reliquia ( Ward, 1988)

Distribution. USA; California.

Comments. This species is a western endemic known from six workers taken in two collections in the spring of 1986. Both collections were taken in the same remnant patch of riparian oak woodland in the Sacramento Valley of California ( Ward 1988) .

Other than pilosity, Strumigenys reliquia is morphologically quite like S. collinsae and shares several mandible characters. In S. reliquia the first tooth arises after a long diastemmic gap and this tooth shorter than the following teeth. These first teeth also do not overlap when mandibles are closed, both characters shared with S. collinsae , but unlike S. collinsae these first teeth are more than half the length of the following teeth where the first teeth in S. collinsae are only about 1/4 the length of the following tooth. Of the four teeth following this first short tooth, the third is shorter than the first two or last. In S. collinsae the third and fourth are nearly equal in size. The clypeal groove is also not visible along the anterior border unlike S. collinsae . Other major differences are discussed under S. collinsae .
