| |
This nocturnal species has a similar nesting pattern as Nylanderia arenivaga, with both possessing polydomous nests with numerous crater entrances (Trager, 1984). Reproductives are produced in the fall, and fly late in winter and early spring; workers are active foragers all year long (Trager, 1984). Nylanderia phantasma was originally thought to only occur in the Lake Wales Ridge area of central Florida, but populations have since been discovered in Alabama, Mississippi, and Georgia (MacGown et al., 2009). Its preference for xeric scrubland dunes may reflect refugia for species adapted to the semiarid areas formed 3,000–15,000 years ago (MacGown et al., 2009). The morphological similarities between N. phantasma and N. arenivaga, in both workers and males, and similar habitat preferences suggest they are sister taxa. Its range is similar to that of N. arenivaga (Kallal & LaPolla, 2012).
Identification
Kallal & LaPolla (2012) - Uniformly pale yellow to whitish in color with pale, whitish pubescence; teeth mandibular reddish; scape macrosetae count low (SMC: 0–4).
Compare with: Nylanderia arenivaga.
This nocturnal species is most likely to be confused with Nylanderia arenivaga. Nylanderia phantasma is generally whitish in color, although it may sometimes be pale yellow. When a little more yellow in color, it can be separated from N. arenivaga by its whitish, rather than brown, macrosetae and not possessing a darkened gastral tip. The mandibles of N. phantasma are reddish rather than the more typical dark brown observed in most Nearctic Nylanderia species. Nylanderia phantasma males have long, outwardly curving digiti, contrasting to N. arenivaga, which has long, but straight digiti. Behaviorally, N. phantasma tends to prefer white sand areas whereas N. arenivaga prefers yellow sands (M. Deyrup, pers. comm.).
