Type material. Holotype. ♁, CHINA: Yunnan, Lushui County, Pianma Township , 9 Km SE, 25.99389°N, 98.66361°E, elevation: 2400 m, 13-18 October 1998, Charles Griswold, David Kavanaugh and Chun-Lin Long leg. (HUN-EP–35A) GoogleMaps . Paratypes: 1♁ 1♀, same data as the holotype (HUN-EP–35B) GoogleMaps .

Etymology. The specific name is a combination of the Latin “ montis- ” (mountain) and “- forma ” (form), referring to the chevron marks on the abdomen; adjective.

Diagnosis. Males of Synagelides montiformis sp. nov. resembles that of S. furcatus sp. nov. ( Figs 15–17 View FIGURES 15–20 , 21–22 View FIGURES 21–22 ), but can be distinguished by the proximal lobe of bulb not bifurcated, and the bulb with only one terminal apophyse ( Figs 23–25 View FIGURES 23–25 , 32–33 View FIGURES 32–35 ), while the proximal lobe of the bulb is bifurcated, and the bulb has two terminal apophyses in S. furcatus sp. nov. ( Figs 15–17 View FIGURES 15–20 , 21–22 View FIGURES 21–22 ). Female of S. montiformis sp. nov. resembles that of S. furcatoides sp. nov. ( Figs 4–6 View FIGURES 4–10 , 13–14 View FIGURES 11–14 ), but can be distinguished by: (1) the hook-shaped copulatory ducts ( Figs 27 View FIGURES 26–31 , 35 View FIGURES 32–35 ), while the copulatory ducts are S-shaped in S. furcatoides sp. nov. ( Figs 6 View FIGURES 4–10 , 14 View FIGURES 11–14 ); (2) the slightly expanded anterior chamber of spermathecae ( Figs 27 View FIGURES 26–31 , 35 View FIGURES 32–35 ), while the anterior chamber of spermathecae is pear-shaped in S. furcatoides sp. nov. ( Figs 6 View FIGURES 4–10 , 14 View FIGURES 11–14 ).

Description. Male ( holotype). Total length 3.59. Carapace 1.76 long, 1.21 wide. Abdomen 1.82 long, 1.09 wide. Clypeus height 0.09. Eye diameters and interdistances: AME 0.46, ALE 0.27, PLE 0.27, AER 1.04; PER 1.09, EFL 0.91. Thoracic groove large, O-shaped. Cervical and radial grooves obvious. Chelicerae ( Fig. 30 View FIGURES 26–31 ) with two promarginal and one retromarginal tooth. Leg measurements: I 3.98 (1.31, 1.84, 0.52, 0.31), II 2.72 (0.92, 1.03, 0.48, 0.29), III 3.04 (1.02, 1.02, 0.69, 0.31), IV 4.06 (1.14, 1.43, 0.98, 0.51). Leg formula: IV–I–III–II. Tibiae I and metatarsi I with two pairs of ventral macrosetae respectively ( Fig. 31 View FIGURES 26–31 ). Abdomen ( Fig. 29 View FIGURES 26–31 ) long, dorsum with six herringbone stripes (the central part of the last one narrow) and two pairs of apodemes, and small gray stripes on both sides. Spinnerets dark yellow.

Palp ( Figs 23–25 View FIGURES 23–25 , 32–33 View FIGURES 32–35 ). Crack of bulb reached to the middle of bulb; distal lobe small; single proximal lobe longer than wide; retrolateral tibial apophysis hook-shaped, bent, and approximately U-shaped; intermediate tibial apophysis small and membranous; ventral tibial apophysis wide and lamellar; distal tibial apophysis two times wider than long; postero-retrolateral cymbial apophysis short, less than 1/5 of cymbium length; embolus slender with wide base and dark retrolateral edge, accompanied by membrane; terminal apophysis strong, plate-shaped, and three times wider than long.

Female ( paratype, HUN-EP–35B). Total length 3.51. Carapace 1.74 long, 1.18 wide. Abdomen 1.76 long, 1.15 wide. Clypeus height 0.09. Eye diameters and interdistances:AME 0.39, ALE 0.23, PLE 0.23, AER: 1.13, PER 1.18, EFL 1.01. Leg measurements: I 3.48 (1.08, 1.57, 0.52, 0.31), II 2.64 (0.78, 0.92, 0.63, 0.31), III 2.91 (0.86, 0.93, 0.71, 0.41), IV 3.83 (1.11, 1.32, 0.98, 0.42). Leg formula: IV–I–III–II. Appearance characteristics same as in male, but darker than male, back of abdomen with grayish black markings, and ventral surface with dense flat hairs.

Epigynum ( Figs 26–27 View FIGURES 26–31 , 34–35 View FIGURES 32–35 ). Epigynum about as long as wide; epigynal hoods located posteriorly; two fossae small, occupying 1/16 of epigynal plate, with distinctly arcuated rims; copulatory openings located posteriorly; width of median septum about 1/8 of epigynal width; copulatory ducts long and S-shaped, ascending obliquely and then extending transverse; spermathecae with two chambers, anterior chamber small and slightly expanded, posterior chamber large and kidney-shaped; junction duct of spermathecae long and narrow.

Distribution. China ( Yunnan Province, Fig. 36 View FIGURE 36 ).
