Temnothorax striatulus

This species is only known from type material and the types have possibly been lost.

Identification
Mackay (2000) - A member of the Temnothorax striatulus species complex. Based on the description and illustrations in Stitz (1937). This species should be easy to recognize as the propodeum is without propodeal spines or angles and completely rounded. The node of the petiole is also low and rounded. The antenna is 12-segmented.

The rounded propodeum will separate this species from all others in the New World."
