( Fig. 6 View FIGURE 6 , 16 View FIGURE 16 , 17 View FIGURE 17 )

Holotype worker, CAMEROON: Prov. Sud-Ouest; Mnt. Cameroon; 3.8 km 330° NNW Mapanja; elev. 1440 m; 4°6.5’N, 9°9.1’E; 16.iv.2000 (B.L. Fisher #2326) ( CASC); 8 paratype workers, same locality as holotype ( CASC, USNM).

Worker diagnosis: metanotal area distinct, with raised metanotal spiracles; head and scapes with appressed pubescence.

Compare with: P. gnoma and subtilis

WORKER. Measurements (n=10): TL: 1.4–1.75; HW: 0.37–0.39; HL: 0.45–0.46; EL: 0.105–0.112; SL: 0.41–0.45; PW: 0.26–0.28; WL: 0.48–0.51; PDH: 0.21–0.23; PrFL: 0.34–0.36; PrFW: 0.098–0.14; GL: 0.45– 0.83. Indices: CI: 80–87; REL: 23–25; SI: 105–120; FI: 28–40

Head yellow, with darker segmental and mandibular margins; slightly longer than broad. A fine, short pubescence covers the head. Scapes surpass posterior margin by about the length of the first 2 funicular segments; scapes with appressed pubescence. Mesosoma compact, yellow to slightly brownish-yellow laterally; fine pubescence covers dorsum. Pronotum rises very steeply from anterior margin to dorsum. Mesonotal area distinct, with prominent mesonotal spiracles. Propodeum possesses a short, angular dorsal face, with a long declivitous face. Legs yellow, with trochanters sometimes whitish-yellow; gaster brownishyellow becoming lighter yellow around segmental margins.

Etymology. The species epithet is a Greek noun in apposition for mountain nymph, in reference to the type locality on Mt. Cameroon.

Non-type material examined: CAMEROON: Prov. Sud-Ouest Mnt., Cameroon, 3.8 km 330° NNW Mapanja, 9° 9.1’ E, 4° 6.5’ S, 16.iv.2000, elev. 1440 m (B.L. Fisher)

Notes. The layer of appressed pubescence covering the head and scapes effectively separates this species from P. subtilis , the species most likely to be confused with P. oreias .
