TYPES: Male holotype and female allotype, from China, on stable scree slope on soil at Lishadi, 500 m before Shibali Yaku ( Pass #31), 3585 m, 27.21354°N, 98.70021°E, Yunnan Province (7 Aug 2005, P. Paquin, PP2405, CASENT 9022602) deposited in HNU (PBI_OON03638) GoogleMaps .

ETYMOLOGY: The specific name is a patronym in honor of Pierre Paquin, who collected the type series and majority of the known specimens.

DIAGNOSIS: The male of this species differs from all congeners except C. schwendingeri in having a palpal bulb that lacks a distinct conductor, and from C. schwendingeri in having a much smaller embolar region (figs. 139–145, 179–181). The female differs from all other Camptoscaphiella in having genitalia with a sinuous copulatory duct (figs. 154–159, 197, 323, 324).

MALE (PBI_OON 02187, figs. 301–310): Total length 2.00. Carapace yellow-brown, surface and sides of pars cephalica very finely striated, lateral margin undulate. Clypeus straight in front view, sloping forward in lateral view; setae dark. Eyes: ALE largest, ALE oval, PME squared, PLE oval; posterior eye row procurved from both above and front; ALE-PLE touching, PME touching for less than half their length. Sternum as long as wide, yellowish white, not fused to carapace, with weak radial furrows between coxae I–II, II–III, III–IV, furrows wrinkled, surface smooth, anterior margin with continuous transverse groove, posterior margin extending posteriorly beyond anterior edges of coxae IV as single extension, lateral margins unmodified, male sternum with a pair of rounded anterolateral processes; setae abundant, dark, originating from surface. Mouthparts: chelicerae, endites, and labium pale orange. Chelicerae straight; promargin with one small tooth; setae dark, evenly scattered; paturon promargin with row of flattened setae. Labium broadly triangular; with 6 or more setae on anterior margin, subdistal portion with unmodified setae. Endites distally excavated, serrula present in single row, anteromedian margin a truncate lobe bearing dense brush of broad setae. Abdomen: pedicel ribbed. Dorsal scutum moderately sclerotized, yellow-brown, covering about 1 ⁄ 2 of abdomen, between 1 ⁄ 4 and 1 ⁄ 2 abdomen width, fused to epigastric scutum, postepigastric scutum pale orange, short, covering about 1 ⁄ 3 of the abdominal length, posteriorly rounded. Spinneret scutum present, incomplete ring; with fringe of needlelike setae. Spinnerets: colulus represented by 2 setae; ALS with 3 spigots, a larger median one surrounded by 2 smaller ones (pyriform); PMS with 2 subequal spigots; PLS with 4 subequal spigots. Dorsum setae dark. Epigastric area dark. Postepigastric area setae dark. Legs: yellow-brown, tibiae with circular depressions on the cuticle that lack visible pores and probably represent regions of muscle attachment. Tarsi I to IV superior claws examined in detail; all surfaces striated; proclaws and retroclaws I–III each with 3 subapical teeth along outer margin; proclaw IV with 2 basal teeth; retroclaw IV with 4 teeth; teeth actually originate from the ventral surface and bend outwards; inner margins without apparent teeth. Trichobothria examined with SEM; hairs plumose, hood with fine striations, base with longitudinal slit, aperture not gratelike. Tarsal organ of palp round with 1 large and 1 medium-sized sensilla; tarsal organ of legs I–II an irregular oval, with 2 large and 1 small sensilla. Epigastric region with sperm pore large, oval, rebordered; with 1 pair of additional orifices mesad of booklung openings (figs. 48–51). Palp not strongly sclerotized, proximal segments red-brown; trochanter normal size; femur one to two times as long as trochanter; patella greatly elongate, longer than other segments combined, tibia and tarsus rounded, subequal, cymbium orange-brown, ovoid in dorsal view; bulb orange-brown, stout, tapering apically, without distinct ventral conductor.

FEMALE (PBI_OON 3056, figs. 311–324): Total length 2.32. As in male except as noted. Carapace brown, anteriorly narrowed to between 0.50 and 0.75 times its maximum width; marginal setae light. Eyes subequal. Sternum yellow-brown, lacking anterior transverse groove (embolarium), lacking anterolateral process. Endites without distal excavation, anteromedian margin lacking lobe or strongly modified setae. Abdomen oval, dorsal scutum covering less than 1 ⁄ 2 of abdomen, not fused to epigastric scutum. Epigastric scutum strongly sclerotized. Postepigastric scutum strongly sclerotized, widely hexagonal, only around epigastric furrow, with short posteriorly directed lateral apodemes, hollow basally and with external opening (fig. 152). Spinnerets: colulus represented by 2 setae; ALS with 4 spigots, a larger median one surrounded by 3 smaller ones (pyriform); PMS with 5–6 subequal spigots; PLS with 9 subequal spigots. Legs: orange-brown; shorter than in male. Tarsal claws as in male, except that female retroclaw IV has only 2 subapical teeth (4 in male). Trichobothria as in male. Tarsal organ I and II large and rounded, with 2 large and 1 small sensilla; tarsal organ of palp, III, and IV small and oval, with 1 large and 1 small sensilla.

NOTES: The copulatory duct of C. paquini is strongly sinuous and somewhat distinct from the straight to slightly curved duct found in all other Camptoscaphiella . At first glance this suggests that the female may be misplaced and would better fit in Ischnothyreus , which is somatically similar and where sinuous ducts are common. Apart from the fact that C. paquini males and females were collected together, a closer comparison with a true Ischnothyreus , also from western Yunnan Province, has turned up additional differences between the two genera. In C. paquini , the copulatory duct opens externally at its anterior end through a small longitudinal slit (fig. 150), and is similar to other Camptoscaphiella that have been closely examined (as in Brignoli, 1976: figs.1–2). In Ischnothyreus , the copulatory duct opens to the outside at its posterior end through a larger opening and (at least in the Yunnan species) has additional invaginations anteriorly (figs. 325, 326, arrow). Thus, it seems reasonable that the female of C. paquini is, indeed, a Camptoscaphiella , albeit one with a unique morphology. In fact, the morphological uniqueness of the female C. paquini , is also shared by the male that, in contrast to most other species, has a much smaller embolar region and lacks a separate ventral prong (“conductor”). A conductor is also apparently absent in C. schwendingeri , which suggests relationship, a possibility that can be tested when females of that species are discovered.
