Nothing is known about the biology of Prenolepis shanialena.


Williams and LaPolla (2016) - In profile view, the anterior border of the mesonotum bulges and rises above the pronotum.

This species is most similar to Prenolepis mediops but has larger compound eyes and a distinct anterodorsal bulge in the mesonotum that rises above the pronotum. Prenolepis shanialena also has a pair of prominent anterolateral lobes on its clypeus, which is not seen in P. mediops.

Light to medium brown; cuticle of head, pronotum, mesopleuron, and gaster smooth and shiny; abundant decumbent setae on scapes and legs; long, erect macrosetae on head, pronotum, mesonotum, propodeum, and gaster; head slightly longer than broad and round in shape with indistinct posterolateral corners and a convex posterior margin; compound eyes moderately large and convex, but do not surpass the lateral margins of the head in full-face view; torulae overlap the posterior border of the clypeus; anterior border of clypeus with a pair of prominent anterolateral lobes (Fig 49); mandibles with 6 teeth on the masticatory margin; ectal surface of mandibles smooth and shiny; in profile view, the anterior border of the mesonotum bulges above the pronotum (Fig 26); propodeum is obtusely angled with a softly rounded dorsal face; dorsal apex of petiole scale is sharply angled and forward-inclined.

Type Material

Holotype worker. Vietnam: Lai Chau Province, Mount Fansipan (K. Eguchi) (Entomological Collection of the Institute of Ecology and Biological Resources: USNMENT00755093); 2 paratype workers, same locality as holotype (National Museum of Natural History: USNMENT00755136).


The specific epithet is a combination of Shani and Alena, the first and middle name of the first author’s fiancée.
