Bolton (2000) - A member of the Strumigenys schulzi-group. Within the group the combination of convex clypeal margin and distribution and form of pilosity, together with the possession of mostly smooth unsculptured pleurae and side of propodeum, is diagnostic of grytava.

Bolton (2000) - Holotype. TL 1.6, HL 0.45, HW 0.33, CI 73, ML 0.08, MI 18, SL 0.20, SI 61, PW 0.21, AL 0.43. Anterior c1ypeal margin evenly convex. Eye relatively large for such a small species, with 4-5 ommatidia in the longest row and about 12 ommatidia in total. Dentition with teeth 1-5 from the base all narrowly triangular and acute, tooth 3 appearing slightly the longest. With mandibles fully closed the masticatory margin proximal of the basal most tooth, a distance about equal to the length occupied on the margin by teeth 1-3 inclusive, is filled with a low, flat basal lamella. Scape slightly dorsoventrally compressed and relatively slender; broadest point of scape is proximal of its midlength. With head in full-face view an anteriorly curved spatulate hair projects laterally in apicoscrobal position, but this hair is not radically different in shape or size from others that precede it on the upper scrobe margin, merely somewhat more elevated. In profile dorsum of head between highest point of vertex and occipital margin with 1-2 pairs of anteriorly curved short hairs that are only slightly longer and more erect than the spatulate ground-pilosity. Pronotal humeral hair short and stout, weakly remiform. Mesonotal dorsum with a single pair of similar standing hairs and similar hairs also present on waist segments and first gastral tergite. Entire katepisternum and most of metapleuron and side of propodeum smooth and shining. Petiole and postpetiole finely reticulate-punctate to reticulate-shagreenate dorsally, the former broader than long in dorsal view. Ventral surface of petiole with a lamellate process anteriorly, followed by an extremely slender crest that is only a tiny fraction of the depth of the peduncle. Basigastral costulae sharply defined and extending over the basal one-fifth to one-quarter of the tergite.
Paratype. TL 1.6, HL 0.45, HW 0.32, CI 71, ML 0.07, MI 16, SL 0.19, SI 59, PW 0.21, AL 0.41.
