This species was taken from orchid plants arriving at Hamburg, Germany, a circumstance agreeing with the large eyes of the worker to indicate an arboreal habitat. (Brown 1962)

Identification

Bolton (2000) - A member of the cordovensis complex in the Strumigenys mandibularis-group. This is the only species of the cordovensis-complex to lack standing pilosity of any form on the first gastral tergite. The pilosity that it does have on this segment is not duplicated by any other species in the complex.

Description

Worker

Bolton (2000) - TL 3.3-3.7, HL 0.72-0.78, HW 0.55-0.61, CI 76-78, ML 0.72-0.76, MI 97-100, SL 0.62-0.65, SI 107-113, PW 0.35-0.40, AL 0.76-0.84 (2 measured).

Characters of cordovensis complex. Ground-pilosity on head and promesonotum dense and conspicuous, curved spatulate; on propodeal dorsum the lateral margins each with a row of posteriorly curved spatulate hairs. Similar dense spatulate pilosity, which is curved posteriorly, is present on dorsum of petiole and postpetiole. First gastral tergite without standing hairs, but with moderately dense minute pointed slender hairs that are appressed and directed posteriorly, these hairs almost pubescence-like in appearance. Apicoscrobal hair present. Cephalic dorsum with a single pair of erect stiff hairs near occipital margin. Pronotal humeral hair stiff, standing hairs otherwise absent from mesonotum, petiole and postpetiole. Tergites behind first with a few fine elongate simple hairs. Distal preapical tooth only slightly closer to apicodorsal tooth than to proximal preapical tooth; all teeth spiniform. Gland bullae proximal of midlength on dorsal surfaces of middle and hind legs. Propodeal declivity with two acutely triangular lobes that are linked by a broad lamella, the ventral lobe longer and somewhat narrower than the dorsal. Head and alitrunk reticulate-punctate except for mesopleuron which is mostly smooth. Disc of postpetiole weakly sculptured with scattered minute rugulae. Gaster smooth behind the short but sharply developed basigastral costulae.

Type Material

Bolton (2000) - Syntype workers, BRAZIL: Amazonas, Manaus, with orchids (intercepted by Plant Quarantine, Hamburg) (Musee d'Histoire Naturelle Genève, Zoologisches Institut und Zoologisches Museum der Universität Hamburg) [examined].
