Type.

Holotype ♂: CHINA, Yunnan, Jinghong City, Mengyang Town, tunnel in Mt. Baihuashan (22°69.529'N, 101°55.210'E, 856 m), 16 July 2012, Q. Zhao & Z. Chen leg. Paratype: 1♀, same data as holotype.

Etymology.

From Latin tortilis (coiled), in reference to the shape of embolus; adjective.

Diagnosis.

The male is similar to that of Agorius lindu Prószyński, 2009 ( Prószyński 2009: figs 7-8, 29-30, 54, 59) by body shape (Fig. 4C) and tegulum (Fig. 3 C–D), but the embolus has 3 coils (Fig. 3D) vs. 1; dorsal-retrolateral tibial apophysis lacking, without terminal hook (Fig. 3B), which is present in Agorius lindu . The female differs from that of Agorius lindu by the shape of the copulatory openings (Fig. 4A), which are small circular holes vs. slanted ovals in Agorius lindu , and the copulatory openings are separated by about two diameters vs. only 1/4 diameter in Agorius lindu .

Abdomen higher and broader than in male, other characters similar. Epigyne heavily sclerotised along the posterior margin (Fig. 4A). Copulatory opening grooves round and separated from each other by two diameters, located 1 diameter from the posterior margin. Vulva: copulatory ducts short and sclerotised, anterior part thicker than the posterior. Receptacles pyriform. Fertilisation ducts elongate and located at the posterior part of the receptacles (Fig. 4B).
