Description

Worker

(MZUSP paratype) (in mm): HL 0.29, HW 0.17, SL 0.09, WL 0.48, CI 58, SI 48.

The combination of the postpetiole as long as the petiole, the coarse foveolate sculpture and the minute mandibular teeth distinguishes this species from all other Leptanilloides. Other relevant characters include: head with parallel sides in full-face view, head sculpture coarse with up to 25 deep foveolae covering a straight transverse line at head midlength; inner margins of the frontal carinae do not touch; flange over the metapleural gland opening pointed posteriorly; petiole, in lateral view, as long as postpetiole; postpetiole nearly as high than the fourth abdominal segment.

Type Material

Holotype worker deposited at NMNH. Colombia: Venecia (near Medellin) # 56–6029, v.1956, Stanley E. Flanders leg. ‘associated with R. fuhrmanni on healthy coffee trees’. Three paratype workers (same series as holotype), deposited one each at American Museum of Natural History, Museum of Comparative Zoology and MZUSP.

Etymology

Sculpturata, a noun in apposition, meaning carved in Latin, referring to the conspicuous deep foveolae that almost cover the head of this species.
