Diagnosis.

This species is similar to M. arcilonga but can be distinguished by the presence of four pairs of cheliceral spines (Fig. 22C View Figure 22 vs. Fig. 16C View Figure 16 ), the palp presence of the cymbial fold, the cymbial process on the tip of cymbium; absence of distal lobe, a paracymbium and a cymbial conductor (Fig. 23A-C View Figure 23 vs. Fig. 17A-D View Figure 17 ). The female can be distinguished by the spermathecae situated at the posterior of vulva, the diameter of copulatory ducts same as spermathecae, fertilization ducts shorter and extended to anterior of spermathecae (Fig. 23E, F View Figure 23 vs. Fig. 18B, C View Figure 18 ).

Description.

Male. See Fig. 22A-D View Figure 22 and Lin and Li (2008): 495.

Palp (Fig. 23A-C View Figure 23 ): the tibia comparatively large, about the two-thirds volume of the bulb, except for retrolateral region, a row of long setae almost encircled the distal brim of tibia (Fig. 23A-C View Figure 23 ). Cymbium translucent, with a median keel and a row of cymbial serrula on the cymbium, the tip extended to be a cymbial process, and long cymbial fold slightly sclerotized, bears a row of short setae (Fig. 23A-C View Figure 23 ). The tegulum with apical apophysis, the embolus short, extended to cymbial conductor and the spermatic ducts can be seen through tegulum (Fig. 23A-C View Figure 23 ).

New morphological data.

Female. Measurements: total length 0.70 Prosoma 0.26 long, 0.27 wide, 0.21 high. Abdomen 0.44 long, 0.44 wide, 0.38 high. Clypeus 0.06 high. Sternum 0.21 long, 0.13 wide. Length of legs: I 0.70 (0.24, 0.08, 0.20, 0.07, 0.11); II 0.64 (0.17, 0.08, 0.18, 0.10, 0.11); III 0.52 (0.16, 0.08, 0.12, 0.07, 0.09); IV 0.61 (0.21, 0.08, 0.12, 0.10 0.10).

Somatic characters (Fig. 22E-G View Figure 22 ). Coloration: same as in male. Prosoma: carapace nearly peach-shaped. Ocular region projecting, eight eyes in two rows, ALE and PLE contiguous. Chelicerae, endites as in male, labium triangle, and sternum scutiform, covers with short setae. Legs: covered with setae and bristles. A sclerotized subdistal-ventral femoral spot present at surface of leg I and II. Abdomen: same as in male.

Epigyne (Fig. 23D-F View Figure 23 ): The scape short, transparent, tip thin (Fig. 23F View Figure 23 ). spermathecae small, nearly round. Fertilization ducts short, derived from dorsal of spermathecae, and extended to anterior of spermathecae. Copulatory ducts sclerotized, the diameter of copulatory ducts same as spermathecae, connected to the lateral of spermathecae (Fig. 23E, F View Figure 23 ).

Distribution.

Southwestern China (Yunnan).
