Minanapis menglunensis  new species

Figs. 4–6, 10

Type material.— Holotype ♂ ( IZCAS), CHINA: Yunnan: Mengla County, Menglun Town , rubber plantation (21°55'N, 101°17'E), elevation 556 m, 10–20 June 2007, G. Zheng.GoogleMaps  Paratypes: 7 ♂, 6 ♀ ( IZCAS), the same data as for holotype.GoogleMaps 

Etymology.—The specific name refers to the type locality; adjective.

Diagnosis.—This new species is similar to these members of Minanapis  in the absence of depressions on the anterolateral corners of the carapace (Figs. 4A, C), female palpal segments extending beyond the coxae, presence of anterior book lungs (Figs. 4E, 6A), male palpal patella fused to tibia, and embolus extending far out from the palpal bulb (Figs 5A, B). It can be diagnosed from other Minanapis  species by uncinate basal apophysis on palpal bulb, larger bulb, shorter conductor, needle-like embolus in the male (Figs. 5A, B), and by saccular, rather than sclerotized, spermathecae and very short copulatory ducts in the female (Figs. 6A, B).

Description.—Male (holotype): Total length 0.69. Carapace 0.34 long, 0.32 wide, 0.30 high. Clypeus 0.17 high. Sternum 0.19 long, 0.17 wide. Abdomen 0.48 long, 0.54 wide. Carapace brown, anterolateral depressions present and pore-bearing; cephalic area smooth, sharply elevated, apex at ocular area; thoracic area with modified pits and rugae on posterior margin. Eyes eight, round, white, in two rows; anterior median eyes smallest, anterior lateral eyes largest, posterior eyes subequal in size. Lateral eyes adjacent. In dorsal view, anterior and posterior eye row straight, equal width. Chelicerae short, slender, covered with long hairs anteriorly and five long plumose setae posteriorly, fang furrow with a promarginal tooth and two short setae. Labral spur small, triangular, not furcated. Sternum brown, modified with pits and reticulate, margin fused to carapace between all legs. Legs yellow-brown, patella with one dorsal spine distally, tibiae I and II with two spines and three trichobothria, tibiae III and IV with one spine and three trichobothria; each metatarsus with one trichobothrium. Leg measurements: I 0.87 (0.26, 0.11, 0.19, 0.11, 0.20); II 0.80 (0.24, 0.11, 0.16, 0.10, 0.19); III 0.71 (0.21, 0.10, 0.14, 0.09, 0.17); IV 0.76 (0.23, 0.10, 0.15, 0.10, 0.18). Leg formula: I-II-IV-III. Abdomen covered with paired sclerotized spots. Dorsal scutum round. Ventral scutum present. Spinneret area with an annular scutum. Palp simple. Palpal patella with a large distal apophysis, the patella fused to tibia. Bulb elliptic, median and apical apophysis absent, only with an uncinate basal apophysis. Embolus long, tube-shaped, situated medially on bulb, extending across and beyond distal tegulum. Conductor about one third of embolus in length. Cymbium with three spines prolateral-distally.

Female: Total length 0.75 (one of the paratypes). Carapace 0.37 long, 0.32 wide, 0.25 high. Clypeus 0.14 high. Sternum 0.20 long, 0.20 wide. Abdomen 0.57 long, 0.68 wide. Coloration and modification same as in male. Cephalic area slightly lower than in male. Pedipalp absent. Leg measurements: I 0.83 (0.25, 0.11, 0.18, 0.10, 0.19); II 0.77 (0.22, 0.11, 0.16, 0.10, 0.18); III 0.67 (0.19, 0.10, 0.13, 0.09, 0.16); IV 0.76 (0.23, 0.10, 0.16, 0.10, 0.17). Leg formula: I-II-IV-III. Abdominal dorsal scutum round. Ventral scutum reticulate, with a pair of posterolateral corners. Epigynal area wrinkled, copulatory openings distinct. Spermathecae relatively large, saccular rugosed, connected to short, sclerotized copulatory duct; copulatory openings situated at posterior surface of epigynal shield.
