Nothing is known about the biology of Prenolepis mediops.

Identification

Williams and LaPolla (2016) - In profile view, propodeum is obtusely angled with a flat dorsal face; compound eyes moderately sized, rounded, and spaced far apart (REL3 < 40).

This species is most similar to Prenolepis shanialena, but is distinguished by its moderately sized compound eyes, which are distinctly smaller and spaced farther apart than those of most other Prenolepis species. The only other Prenolepis species with compound eyes comparable in relative size and position is Prenolepis melanogaster, which is a much larger species (TL > 4.25mm) that has a yellow-brown head and mesosoma and a dark brown to black gaster.

Light to medium brown; antennae and mandibles distinctly much lighter in color when rest of body is medium brown; cuticle of head, pronotum, and propodeum smooth and shiny; cuticle of gaster lightly reticulate; abundant decumbent setae on scapes and legs; long, erect macrosetae on head, pronotum, mesonotum, and gaster; head about as long as broad and round in shape with indistinct posterolateral corners and a straight posterior margin; compound eyes moderately sized, convex, and spaced far apart (REL3 < 40); compound eyes do not surpass the lateral margins of the head in full-face view; torulae overlap with the posterior border of the clypeus; clypeus with prominent anterolateral lobes; mandibles with 6 teeth on the masticatory margin; ectal surface of mandibles with light longitudinal striations; in profile view, propodeum is obtusely angled with a flat dorsal face; dorsal apex of petiole scale is sharply angled and forward-inclined.

Type Material

Holotype worker. China: Yunnan Province, Gaoli-gong Shan, Nujiang State Nat. Res., 27.715°N 98.565°E, 2000m, 09– 14.vii.2000 (D.H. Kavanaugh, C.E. Griswold, D. Ubick, H.M. Yan, D.Z. Dong, H.B. Liang) (National Museum of Natural History: CASENT0203583). 2 paratype workers, same locality as holotype (USNM: CASENT0203584, CASENT0203585).

Etymology

The specific epithet is named for the moderately sized compound eyes of this species.
