Identification

Bolton (2000) - A member of the mandibularis complex in the Strumigenys mandibularis-group. The propodeal declivity is deeper in saliens than is usual in most members of the mandibularis-complex, where the propodeum tends to be depressed and the declivity quite short. The depth of the declivity and its armament effectively separates saliens from the closely related Strumigenys prospiciens. Also, the latter species has long fine hairs that arise all over the surface of the first gastral tergite, whereas in saliens such hairs are restricted to the base of the sclerite.

Description

Worker

Bolton (2000) - TL 3.5-3.9, HL 0.88-1.00, HW 0.64-0.71, CI 69-77, ML 0.54-0.60, MI 59-64, SL 0.62-0.70, SI 90-106, PW 0.40-0.45, AL 0.85-1.00 (12 measured).

Characters of mandibularis-complex. Proximal preapical tooth slender, located just distal of the midlength on the inner mandibular margin. Length of proximal preapical tooth is usually less than the distance separating it from the distal tooth; rarely otherwise. Outer margins of mandibles more or less straight, only very feebly convex at full closure. Propodeum in profile with a distinct triangular tooth at top of declivity and another at the base, the two widely separated and linked only by a narrow concave carina. Disc of postpetiole reticulate-punctate, distinctly broader than long. First gastral tergite with fine standing hairs present on basal quarter or less. Basigastral costulae extremely short sparse and poorly defined, vestigial in some samples.

Queen

Brown (1954) - TL 4.2-4.5, HL 0.88-0.93, ML 0.50-0.53, WL 0.99-1.02 mm.; CI 73-82, MI 57-61; forewing L 3 mm. or slightly more. Eyes very large and convex. Mesonotum evenly and densely punctulate, with a feeble median sulcus and a few long, posteriorly-inclined hairs. Nearly all of mesopleura smooth and shining. Petiolar node broader than long and flattened obliquely from in front and above, as in the Strumigenys smithii worker, but a little less extreme. Color much as in worker. Forewing venation: Rs+M and M distal to this lacking, as are also cu-a and m-cu. Rs weak; rest of venation fairly well preserved. Posterior wing with four hamuli.

Type Material

Bolton (2000) - Syntype workers and queens, BRAZIL: Santa Catarina (Hetschko) (Naturhistorisches Museum Wien, Vienna, The Natural History Museum, National Museum of Natural History) [examined].
