(Smith, D.R. & Lavigne, 1973)
The yellow coloration in this species is probably an adaptation, reflecting the fact that workers are nocturnal foragers (J.S. LaPolla, personal observation). At El Verde Field Station in Puerto Rico, during the day no workers were ever seen foraging, but at night it was one of the most commonly encountered ant species, often observed in large foraging trails with hundreds of individual workers moving on the forest floor. This appears to be a tree hollow-nesting species, as nests were observed by both Smith & Lavigne (1973) and J.S. LaPolla in living tree hollows at a height of about 1–1.5 m from the ground.

This is the only yellow species known in the genus, and is therefore easy to identify.
Smith, D.R. & Lavigne (1973) - The long antenna of Z. cisipa resembles that of Paratrechina longicornis but has 6-toothed mandibles and suberect hairs on the antennal scapes and tibiae. It is separated from other species of Nylanderia by the long antenna, suberect hairs on all surfaces of the antennal scapes and tibiae, presence of 2 pairs of macrochetae on the pronotum, and the pale yellow coloration.

Smith, D.R. & Lavigne (1973) - The type colony was established inside a hollow in the trunk of a living tree (Roystonea borinqueiia O. F. Cook) at a height of 4 feet. The hollow was partly filled with sawdust and/or frass, and the workers had constructed tunnels within. The colony was composed of several hundred workers, probably exceeding a thousand.

Holotype: Length, 3.3 mm; head width, 0.6 mm; head length, 0.7 mm; length of antennal scape, 1.1 mm; eye length, 0.19 mm. Head, thorax and legs pale yellow, head slightly darker; gaster pale gray, darker than head and thorax. Shining, with dilute, whitish, appressed pubescence; antennal scape with suberect, whitish hairs on all surfaces, not bristlelike as other erect hairs of head and body; macrochetae of head mostly on clypeus, frons and vertex; pronotum with 2 pairs of macrochetae, mesonotum with 2 pairs of macrochetae; each femur with few macrochetae, mostly on inner surfaces; each tibia with fine, suberect hairs on all surfaces, similar to those of antenna! scapes; macrochetae on gaster rather evenly distributed on segments.
Antenna 12-segmented; scape long, surpassing posterior margin of head by nearly ½ its own length. Eye with about 11 facets in greatest diameter, 8 facets in shortest diameter; separated from mandibular insertion by distance of about 1 1/4 its greatest diameter. Clypeal border entire, not emarginated; each mandible with 6 teeth; maxillary palpus long, 6-segmented; ocelli distinct. Thorax in profile with mesonotum and pronotum evenly curved; meso-epinotal depression distinct. Petiolar node distinct, inclined.

Overall brownish yellow, with darker gaster; head with layer of pubescence and distinctly convex eyes; scapes with dense layer of short, slender, decumbent setae; mesosoma with scattered erect setae on pronotum and mesonotum; dorsal face of propodeum gently rounded; gaster with dense layer of pubescence.

Mostly pale, dirty yellow to orange with gaster a little darker than head and thorax and antenna and legs nearly whitish. Faintly shining, somewhat dulled by appressed whitish pubescence. Bristlelike macrochetae absent. Suberect hairs present on all surfaces of each antennal scape and tibia; longer erect hairs moderately abundant on head, thorax and gaster and a few on inner surface of each femur.
Antenna 12-segmented; scape long, surpassing posterior margin of head by nearly 1/2 its own length. Distance between mandibular insertion and eye slightly less than greatest eye length. Forewing with a radial and a cubital cell; no discoidal cell. Most other features as for worker.
