etymology L quadricepsHNS, square-headed, referring to head shape in frontal view.

Diagnosis a medium-sized, yellow member of the flavensHNS group whose major is distinguished by its square head shape in full-face view, angulate profile of the mesonotal convexity, and large propodeal spines.

Similar to carinataHNS of montane Costa Rica but differs in the major by its much longer propodeal spine, more extensive sculpturing on the head, lack of a rugoreticulum on the mesosoma, and color; and in the minor by the absence anywhere of rugoreticula; and by color.
