Nomenclature

 *  clotho. Pyramica clotho Bolton, 2000: 413 (w.) BORNEO. Combination in Strumigenys: Baroni Urbani & De Andrade, 2007: 117

Worker
Holotype. TL 2.3, HL 0.60, HW 0.41, CI 68, ML 0.14, MI 23, SL 0.32, SI 78, PW 0.28, AL 0.59. Closely related to Strumigenys disjuncta and mostly matching the description of that species. The dense pilosity of Strumigenys clotho, although basically of the same form as disjuncta, tends to be of narrower and slightly longer hairs throughout. Easily seen diagnostic characters that separate the two are as follows.

S. clotho: Apicoscrobal hair present. Base of first gastral sternite without a pad of spongiform tissue. With petiole and postpetiole in profile the posteriormost rows of dorsal hairs long and stoutly remiform, elevated and curving posteriorly, extending well beyond the posterior collars of the waist segments. Standing stout hairs on first gastral tergite restricted to a single transverse row very close to the base.

S. disjuncta: Apicoscrobal hair absent. Base of first gastral sternite with a thick pad of spongiform tissue. With petiole and postpetiole in profile the posteriormost rows of dorsal hairs short and broad, scale-like and closely applied to the surface, scarcely reaching beyond the posterior collars of the waist segments. Standing stout hairs on first gastral tergite present on basal half of sclerite in a series of transverse rows that diminish in width posteriorly.
