Genus Nylanderia Emery, 1906

The following characters differentiate individuals to which the name Nylanderia refers from other individuals of Formicinae ( LaPolla et al. 2010; Williams & LaPolla 2016): mandibles of females with 6 teeth (see Nylanderia opisopthalmia for an exception); eyes placed slightly anterior to the midline of head (see Nylanderia opisopthalmia for an exception); outer margin of mandibles without longitudinal striations; deep and complete mesosomal sutures; maxillary palps 6-segmented; labial palps 4-segmented; erect setae on dorsum of head; males with ‘well developed’ mandibles, each with a prominent apical tooth and often a small basal tooth (or just a pronounced basal angle); in lateral view, males with dorsal margin of mesonotum (i.e. mesoscutum and mesoscutellum) flat; males with the 9 th abdominal sternite often obscured by 8 th sternite.
