Etymology

Diagnosis
The male resembles that of Nannenus maughami Prószyński & Deeleman-Reinhold, 2012 (see Prószyński and Deeleman-Reinhold 2012[1]: figs 97–99), but the RTA is straight and shorter, about 1/4 the length of the cymbium (Fig. 28B) vs. apically bent in Nannenus maughami. The female can be distinguished from other congeners by the boomerang-like copulatory openings (Fig. 29A).

Legs: I 6.00 (2.00, 1.10, 1.25, 0.90, 0.75); II 5.45 (1.65, 1.00, 1.20, 0.85, 0.75); III 5.48(1.70, 0.85, 1.00, 1.10, 0.83); IV 6.52 (1.95, 0.92, 1.50, 1.35, 0.80).

Spination of leg I: femur d2-1-1; tibia v2-2-2; metatarsus v2-0-2. Palpal tibia short, about 1/5 the length of the cymbium, RTA straight, as long as tibia (Fig. 28B). Cymbium bent. Bulb elongate, set obliquely, with peripheral seminal duct. Embolus arising from basal-retrolateral part of the bulb, running parallel to bulb and extending to the tip of the cymbium (Fig. 28C).
Female (one of paratypes, same locality as holotype). Total length 9.26, CL 4.00, CW 2.56, AL 5.26, AW 2.38. Eye measurements: AME 0.79, ALE 0.39, PME 0.08, PLE 0.34, AER 2.28, PER 2.30, EFL 2.10. Clypeus 0.13 high. Legs: I 6.57 (2.15, 1.34, 1.48, 0.90, 0.70); II 6.02 (1.90, 1.20, 1.25, 0.95, 0.72); III 6.11 (1.90, 1.08, 1.00, 1.34, 0.79); IV 7.77 (2.28, 1.18, 1.72, 1.80, 0.79).
Spination of leg I: femur d0-1-0; tibia v2-2-2; metatarsus v2-0-2. Other characters similar to those of male. Epigyne with two rectangular posterior projections and central bulge formed by the copulatory ducts (Fig. 29A). Copulatory openings boomerang-like, located anteriorly. Copulatory ducts short, receptacles round, fertilisation ducts at the anterior part of the receptacles (Fig. 29B).
