Nomenclature

 *  substricta. Glamyromyrmex substrictus Kempf, 1964e: 68, figs. 21-23 (w.) BRAZIL. Combination in Pyramica: Bolton, 1999: 1672; in Strumigenys: Baroni Urbani & De Andrade, 2007: 128. See also: Bolton, 2000: 239.

Worker
Bolton (2000) - S. substricta differs from the closely related Strumigenys perissognatha as follows.

S. substricta: Basal lamella of mandible no taller than basal tooth; lamella partially visible in full-face view at full closure. Outer margin of mandible evenly convex from apex to margin of clypeus. Anterior clypeal margin broadly evenly concave. Upper scrobe margins shallowly divergent-concave immediately posterior to clypeus. Pronotum bluntly marginate dorsolaterally. Pronotum (at humeri) and mesonotum each with a pair of flagellate hairs. Short flagellate hairs present on waist segments and gaster. Pronotal disc smooth, remainder of dorsal alitrunk sculptured. Petiole node sculptured dorsally. Spongiform tissue absent from anterior face of petiole node. Lamella on declivity below propodeal spine narrow, much of spine freely projecting.

Strumigenys perissognatha: Basal lamella of mandible taller than basal tooth; lamella not visible in full-face view at full closure. Outer margin of mandible sharply angled just in front of margin of clypeus. Anterior clypeal margin narrowly and deeply concave medially. Upper scrobe margins shallowly divergent-convex immediately posterior to clypeus. Pronotum not marginate dorsolaterally. Pronotum and mesonotum without flagellate hairs. Short flagellate hairs absent from waist segments and gaster. Entire dorsal alitrunk smooth. Petiole node smooth dorsally. Spongiform tissue forming a collar across anterior face of petiole node. Lamella on declivity below propodeal spine very broad, only extreme apex of spine free.

Type Material
