Etymology. Named after Miss Isobel 'Issy' Millett, a close friend of the author’s family.

Diagnosis. The new species may be separated from N. schuelkei sp. n. and N. katyae by the form of the mesoventral keel which does not extend below the mesocoxae. In this respect it is similar to N. pilosellum , and the North American species N. americanum Motschulsky and N. amoenum Motschulsky but these are less rounded and more parallel sided species.

Type data. Holotype: ♀, Costa Rica , Alajuela, Peñas Blancas , 820m, 19 May 1989, J. Ashe, R. Brooks, R. Leschen; Snow Entomological Museum , Costa Rican Expedition,#279; ex. with ants under bark (MM). Fragments of a second specimen from the same locality, ex. Xylaria , 17 May 1989, mounted as a slide, are also in MM.
