Holotype worker, CUBA: Holguin, 6 km S Yamanigüey , 20° 33’ N, 74° 44’W, 25 m, 23.viii.2001, P.S. Ward #14437- 23 ( NMNH)GoogleMaps  ; 2 paratype workers same locality data as holotype (specimens are from the same nest as holotype)GoogleMaps  ; 3 paratype workers same locality data as holotype but different collecting code (P.S. Ward #14436) ( NMNH & MCZC).GoogleMaps 

Worker diagnosis: Larger brown to light brown species (HL: 0.6–0.72); SMC typically greater than 30 (measured range: 26–38); head in full-face view distinctly ovate with rounded posterolateral corners.

Compare with: N. sierra  , N. xestonota 

WORKER. Measurements (n=7): TL: 2.20–2.84; HW: 0.54–0.6; HL: 0.60–0.72; EL: 0.15–0.18; SL: 0.78–0.87; WL: 0.76–0.85; GL: 0.82–1.3; SMC: 26–38; PMC: 4–6; MMC: 3–4. Indices: CI: 83–90; REL: 24–25; SI: 141–152; SI2: 18–21.

Head: Sides of head in full face view rounded and slightly convergent anteriad; posterolateral corners distinctly rounded; posterior margin straight; anterior clypeal margin emarginate; median ocellus present; eye well-developed. Mesosoma: in lateral view, pronotum convex; anterior margin of mesonotum raised slightly above posterior pronotal margin; metanotal area without short flat area before spiracle; dorsal face of propodeum slightly convex; dorsal face of propodeum lower than mesonotum in lateral view. Color and pilosity: color light brown to brownish-yellow; slightly darker dorsally; mesocoxae and metacoxae slightly lighter than the mesosoma; head generally without pubescence, except some sparse pubescence laterally and underneath eyes; mesosoma generally without pubescence, except some sparse pubescence on the mesonotum and a sparse fringe along dorsal face of propodeum; gastral tergites with abundant pubescence.

Other material examined: CUBA: Santiago de Cuba: Parque Nacional Gran Piedra, near La Isabellica, 20.00700, -75.61900 +/- 150 m, 1115 m, 29 Jan 2012, R.S. AndersonGoogleMaps  # RSA 2012-013.

Etymology: Named in honor of Philip S. Ward (University of California—Davis), who not only collected this species, but whose many superb contributions to myrmecology have greatly enriched the field.

Notes: Workers of this species are very similar to N. sierra  , but N. wardi  is much larger and the declivity following the mesonotum to the metanotal area is distinctly longer in N. wardi  . Additionally, N. wardi  has much more scape macrosetae than N. sierra  . There were individuals of N. sierra  collected in sympatry with N. wardi  and the morphological differences between the two species were maintained.
