Comments. Pheidole inermis is a version of P. biconstricta that lacks any trace of a propodeal spine. There is continuous variation in the size of the propodeal spine in P. biconstricta , and in some cases it is reduced to a minute denticle. DNA barcoding data places three specimens that lack the propodeal spine among P. biconstricta specimens. I treat P. inermis as an extreme of variation within P. biconstricta .
