Type material
Holotype ♂ China, Yunnan, Menglun, XTBG, Paramichelia baillonii plantation; 21°53.823'N, 101°17.072'E; 613 m; pitfall traps; 1–15 May 2007; Guo Zheng leg. (SYNU-481). Paratypes [same data as holotype except where indicated] 1♂ (SYNU-482); 1♂ (SYNU-494); 1♂1♀, pitfall traps, 16–31 June 2007 (SYNU-483–484); 1♂, pitfall traps, 1–9 Dec. 2006 (SYNU-485); 1♂, pitfall traps, 1–9 Dec. 2006 (SYNU-486); 1♀ (SYNU-487); 1♂1♀, XTBG, Secondary tropical montane evergreen broad-leaved forest, 21°54.813'N, 101°12.634'E, 876 m, pitfall traps, 16–24 Sep. 2006, Guo Zheng leg. (SYNU-488–489); 1♂1♀, pitfall traps, 1–15 July 2007 (SYNU-490–491); 1♂1♀, pitfall traps, 16–31 June 2007 (SYNU-492–493).
Diagnosis
This new species is similar to C. schwendingeri Baehr, 2010 (female unknown), but can be distinguished by the long, strongly-curved setae between the cheliceral paturons (Figs 1F, G, 2A–C) and a uniformly coloured carapace (vs setae absent and the carapace with a longitudinal brown stripe (Baehr and Ubick 2010[1]: figs 327–331)). Females of this new species can be distinguished from congeners by the star-shaped structure of the endogyne and the strongly-curved copulatory duct (Fig. 3H–J).
Description
Male (holotype): Body: uniformly colored, yellow; habitus as in Fig. 1A, C, E; length 1.29. Carapace (Fig. 1B, F): 0.65 long, 0.59 wide; pars cephalica strongly elevated in lateral view, surface of elevated portion and sides of pars cephalica finely reticulate. Eyes (Fig. 1B, G): ALE 0.057; PME 0.049; PLE 0.049; ALE circular, PME oval, PLE oval; posterior eye row procurved from both above and front; ALE separated by less than one radius. Clypeus (Fig. 1F, G): margin unmodified, straight in front view, sloping forward in lateral view. Mouthparts (Figs 1F, G, 2A–C): with several long, strongly-curved setae between paturons. Sternum (Fig. 1D): as long as wide, pale orange, surface finely reticulate. Abdomen (Fig. 1A, C, E): 0.67 long, 0.41 wide; oval, scuta pale orange; dorsal scutum covering about 2⁄3 of abdomen length, between 1/2 and 3⁄4 of abdomen width, not fused to epigastric scutum; postgastric scutum small, just near epigastric furrow. Legs: pale orange. Palp (Figs 1H, I, 2D–K): reddish-brown; patella extremely long club-shaped, about 4.3 times of the femur length, and 2.1 times of the bulb length; cymbium narrow in dorsal view; distal part of bulb with a broad ventral process (vp) and a narrow dorsal process (dp), the dorsal one with basally wing-shaped appendices (wa). Female (SYNU-484): Body: habitus as in Fig. 3A–C; length 1.37. Carapace: 0.62 long, 0.57 wide. Eyes: ALE 0.065; PME 0.049; PLE 0.057. Mouthparts: chelicerae unmodified. Abdomen: 0.79 long, 0.52 wide. Epigastric area (Fig. 3H, I): surface without external features. Endogyne (Fig. 3J): with an anterior star-shaped structure (ss); copulatory duct (cd) very long, strongly curved; apodemes thread-shaped (a).
Etymology
The specific name is derived from Chinese pinyin, “changxu”, which means “macrochaeta”, referring to the long, curved setae between male cheliceral paturons; noun in apposition.
Comments
The male chelicerae are unmodified in species considered to belong to the genus (Baehr and Ubick 2010[1]). The long, strongly-curved setae between male cheliceral paturon of this species are unique in this genus, even in the entire order.
Distribution
Known only from the type locality.
