Specimen Labels

Synonyms

Morphology features (small eyes, pale pigmentation) suggest foragers are nocturnal or hypogaeic.

Identification

LaPolla and Kallal (2019) - Uniformly pale yellow with very small eyes (REL: 9–11; SI2: 7–9).

Compare with Nylanderia zaminyops.

Nylanderia myops is quite distinct in its morphological appearance with very small eyes and a uniformly pale-yellow body color. The only other species it could be confused with is N. zaminyops which is known from Trinidad. The relative eye index is smaller in N. myops (REL 9–11) compared with N. zaminyops (REL 13–17). In N. myops the dorsal face of the propodeum is relatively flat and long, in contrast to the more rounded and short propodeal dorsal face of N. zaminyops.

Biology

While little is known about the biology of this species, its morphology (small eyes and very pale coloration) suggests it is either a hypogaeic or nocturnal forager. It has been collected from several localities across Cuba in sifted leaf litter and/or rotten wood. The type series was collected under a stone (Mann, 1920).

Description

Worker

LaPolla and Kallal (2019) - (n=2): TL: 2.10–2.20; HW: 0.43–0.44; HL: 0.53–0.55; EL: 0.05–0.06; SL: 0.65– 0.67; WL: 0.67–0.69; GL: 0.85–0.98. SMC: 16–19 PMC: 3; MMC: 2. indices: CI: 78–83; REL: 9–11; SI: 147–155; SI2: 7–9.

Head: sides of head in full face view nearly parallel; posterolateral corners rounded; posterior margin straight, slightly emarginate medially; anterior clypeal margin emarginate; ocelli absent; eye small. Mesosoma: in lateral view, pronotum convex; anterior margin of mesonotum raised slightly above posterior pronotal margin; metanotal area without a short flat area before spiracle; dorsal face of propodeum relatively flat; dorsal face of propodeum lower than mesonotum in lateral view. Color and pilosity: uniformly pale yellow; except on scapes with abundant pubescence, pubescence absent to sparse, most abundant on mesonotum and dorsum of gaster.

Type Material

LaPolla and Kallal (2019) - 6 syntype workers, CUBA: Mina Carlota, Trinidad Mts. (National Museum of Natural History) (examined). Male and queen specimens described by Mann (1920) could not be found despite an extensive search of the Museum of Comparative Zoology and NMNH collections.
