Taxonomic History (provided by Barry Bolton, 2013)
Southern Mexico to Costa Rica. Costa Rica: Atlantic slope (La Selva, Braulio Carrillo, Penas Blancas, Monteverde).
This species inhabits mature wet forest from sea-level to lower cloud forest. It is moderately abundant in Winkler samples and at baits on the forest floor. Nests have been found in dead wood on the ground and in shallow chambers in clay soil.
Several strongly divergent DNA barcoding clusters occur, but so far no morphological correlates are known.

Wilson, E. O.:
etymology L rectispina , upright spine.
diagnosis Similar in various traits to bilimeki , floridana , hazenae , rectiluma , rectisentis , rectitrudis, sospes , and stomachosa , differing as follows.
Major: propodeal spine half as long as propodeal basal face and perpendicular to it; humeri low and subangulate; mesonotal convexity present; postpetiole from above elliptical, with angulate lateral margins; all of dorsal surface of head except occipital lobes, frontal triangle, and midclypeus carinulate; all of mesosoma and most of head and waist foveolate and opaque; anterior fringe of first gastral tergite shagreened.
Minor: propodeal spine half as long as the propodeal face and vertical on it; postpetiolar node somewhat depressed; occiput broad, its margin concave; all of head and mesosoma foveolate and opaque, no rugoreticulum and almost no carinulae.
