Paraparatrechina glabra (Forel, 1891) |
A forest species that feeds on small soil invertebrates. (Lampasona 2015)
Identification
LaPolla et al. (2010) - Elongate mesosoma (WL: 0.4–0.6), with pronotum rise of about 45° from anterior margin to dorsum; REL ≥ 20.
Compare with: Paraparatrechina myops and Paraparatrechina ocellatula. Workers of this species are easily distinguished from the other Malagasy Paraparatrechina by the presence of large eyes.

Description
Worker
(n=39): TL: 1.38–2.22; HW: 0.35–0.48; HL: 0.41–0.58; EL: 0.1–0.129; SL: 0.47–0.64; PW: 0.25–0.33; WL: 0.44–0.66; PDH: 0.21–0.28; PrFL: 0.35–0.48; PrFW: 0.1–0.134; GL: 0.476–0.91. Indices: CI: 75–102; REL: 20–26; SI: 104–140; FI: 24–36.
Head brownish-yellow to yellowish-brown, with darker segmental and mandibular margins; head slightly longer than broad. Head pubescence variable from appressed to suberect, with a shining cuticular surface. Scapes surpass posterior margin by about the length of the first 4 funicular segments; scapes with appressed pubescence. Mesosoma brownish-yellow to yellowish-brown and elongate; fine, appressed pubescence covers entire mesosomal dorsum. Pronotum rises about 45° from anterior margin to dorsum; propodeum possesses a short, angular dorsal face with a long declivitous face. Legs are often lighter in color than the mesosoma, with the trochanters and tarsi often whitish-yellow. The gaster is similarly colored as head and mesosoma.
Queen
(n=1): TL: 5.09; HW: 1.0; HL: 0.94; EL: 0.29; SL: 0.97; PW: 1.09; WL: 1.79; PDH: 0.58; PrFL: 0.88; PrFW: 0.27; GL: 2.36. Indices: CI: 108; REL: 28; SI: 96; FI: 30.
As in worker, with modifications expected for caste. Pubescence very dense, extending from dorsum to lateral regions of the mesosoma.
Male
(n=3): TL: 2.1–2.28; HW (including eyes): 0.52–0.53; HL: 0.45–0.47; EL: 0.2–0.22; SL: 0.33–0.34; PW: 0.38–0.38; WL: 0.69–0.71; PrFL: 0.52–0.56; PrFW: 0.11–0.12; GL (including parameres): 0.94–1.1. Indices: CI: 112–115; REL: 44–46; SI: 63; FI: 6–21.
Head dark brown, with bulging large eyes that occupy most of the lateral region of the head; three prominent ocelli present. Head slightly broader than long. Palps distinctly lighter than head in color. A dense layer of pubescence covers head. Scapes surpass posterior margin by less than half of the length of the first funicular segment; scapes are slightly lighter in color than surrounding head. Antennae 13-segmented. Mandible with apical tooth and indistinct basal angle. Mesosoma dark brown as in head; pronotum short and collar-like; mesonotum large, rounded anteriorly, overarching pronotum; mesosoma dorsum flat, with suberect setae. Declivity indistinct from propodeum; propodeum lower than mesonotum and scutellum. Gaster dark brown, covered with pubescence and scattered erect setae. Parameres elongate, with scattered erect setae, especially towards apices.
Type Material
3 syntype workers examined, MADAGASCAR (Musee d'Histoire Naturelle Genève).
