[ hardwickii (Gervais, 1843) “complex”] Figures 1–18 View Figures 1–11 View Figures 12–18
Material examined: Female and male immature specimens, CHINA: Hubei Province, Jingzhou , Jingshan County, Huzhaoshan Mountains , 3 June 2007, Guanglin Xie leg. ( MWHU, Ar.-MWHU-HBJS0701–02). These specimens were dry with two pinholes penetrating female’s carapace and male’s genital opercula; we placed them in 75% alcohol .
According to the revision of Scorpiops published by Kovařík (2000), and further considerations given by Kovařík & Ahmed (2009), forms belonging to S. hardwickii (Gervais, 1843) “complex”, have 6–8 ventral trichobothria and 17 external trichobothria on the patella; pectinal teeth number 4–9; pectines without fulcra; chela manus length to width ratio is about 1; tegument coarse.
Scorpiops hardwickii “complex” can be distinguished from S. jendeki Kovařík, 1994 , which is the most geographically close species of the genus in China, by the following features: (1) carapace with dense granules, while in S. jendeki it bears very sparse large granules; (2) the manus of pedipalps dorsally with coalescing large granules forming clear dorsoexternal carinae; in S. jendeki , irregular rows of granules form a loose dorsoexternal carinae; (3) chela fingers strongly curved, while they are straight in S. jendeki .
Description (based on an immature female specimen):
Coloration: Mostly yellow-brown to red-brown. Carapace dark brown, Median and lateral ocular tubercles black. Tergites mainly dark red-brown. Metasoma segments dark red brown with yellow brown stripes; vesicle red-brown with a yellowish aculeus. Chelicerae yellow-brown, with fingers red-brown and gradually lighter toward the tip. Pedipalp femur and patella dark brown; and the chela red-brown. Legs yellow brown. Claws yellowish brown. Sternum, genital operculum, venter and sternites brown. Pectines yellowish.
Morphology: Carapace coarse ( Figure 1 View Figures 1–11 ), with dense, minute granules; lateral furrow broad and flat; anterior median furrow broad and moderately deep; posterior median furrow deep; anterior margin smooth; posterior and lateral margins and other parts with dense, minute granules, anterior granules larger than the posterior ones. Median eyes situated anterior to the center of the carapace; three pairs of lateral eyes, the third smallest. Median ocular tubercle smooth with a pair of median eyes, which larger than the first two pairs of lateral eyes. Lateral ocular tubercle smooth with some granules ( Figure 4 View Figures 1–11 ).
Mesosoma: Tergites are almost completely densely covered with fine granules, posterior part of tergites with some bigger ones; from tergite II to VI the trace of a median carina first appears and gradually becomes distinct; on tergite VII with a distinct carina and two pairs of lateral carinae. Pectinal tooth count 6/6, fulcra absent ( Figure 7 View Figures 1–11 ). Genital opercula subtriangular. Sternites smooth and shiny; segment VII ventrally with four weak carinae.
Metasoma: Segments II to V are longer than wide; segments I to V have 10-8-8-8-7 carinae, segments II–IV with a pair of vestigial lateral carinae; all dorsal carinae are dentate on segment I, and gradually become strongly serrated from II to IV; with tegument coarse and punctated; on segment V, carinae with smaller serration dorsally and larger serration ventrally. Vesicle smooth, with some sparse granules and few setae ( Figure 11 View Figures 1–11 ).
Pedipalps: Tegument coarse. Femur with external, dorsointernal, dorsoexternal, ventrointernal, ventroexternal carinae granulated and internal carinae crenulated. Patella with dorsointernal, dorsoexternal, ventrointernal, ventroexternal and external carinae with large, smooth granules; two small spinoid granules present on the internal aspect ( Figure 15 View Figures 12–18 ). Trichobothrial pattern C, neobothriotaxic (Vachon, 1974); patella with 17 external trichobothria (5 eb, 2 esb, 2 em, 4 est, 4 et) and 8 ventral trichobothria ( Figure 15 View Figures 12–18 ). Chela with 4 ventral trichobothria, with dorsal marginal, external secondary, and ventral internal carinae, all smooth ( Figures 16–18 View Figures 12–18 ); ventral internal carina only with a row of large granules. Fingers curved ( Figure 10 View Figures 1–11 ).
Chelicerae: Tibiae smooth, with reticulated pattern. Movable finger with 4 denticles on dorsal edge and 4 denticles on ventral edge. Fixed finger with 3 denticles on dorsal edge ( Figures 2–3 View Figures 1–11 ).
Legs: Tegument coarse except trochanter. Trochanter with few granules and setae. Femur dorsal surface densely granulose and ventrally smooth, internally with 2 granular carinae. Patella dorsally with scattered small granules, and dorsoexternal, dorsal and ventroexternal 3 granular carinae. Tibiae with few setae, without spurs. Basitarsus with more setae, and two lateral pedal spurs. Tarsus ventrally with row of spinules. Claws hooklike.
Variation. Female and male: coloration and morphology are very similar. Number (left/right) of ventral trichobothria on the pedipalp patellae: female with 8/8, male juvenile with 8/8. Number of pectinal teeth: female with 6/6, male juvenile with 8/7. Measurements are not provided as these specimens are immature.
Habitat: Found under stones on a hillside with many stones and ruderal vegetation.
