Storenomorpha paguma  sp. nov.

( Figs. 1­12View FIGURES 1 – 6View FIGURE 7View FIGURE 8 – 10View FIGURES 11 – 12)

Type material: Male holotype from VIETNAM: HA TINH Prov.: Huong Son District, An River, Huong Son Forest, 13 Km W Rt. 8, ca. 18 ° 20 ' 52 "N, 105 ° 14 ' 41 "E, (ref. HS 52) 680 m, mammalogists pitfalls, 23.IV. 1998, D. Silva, one male paratype ( SEM preparation MJR 138) same data (ref. HS 31), 12.V. 1998 (both deposited in AMNH).

Etymology: The specific name refers to the masked palm civet ( Paguma  larvata), a common viverrid carnivore in the Oriental Region, and is an allusion to the central white and contrasting band on the carapace, which resembles the color pattern of the civet’s face.

Note: Males and females were collected from localities separated by about 100 km, and are provisionally matched by their very similar appearance.

Diagnosis: Males of the new species resemble those of S. reinholdae  and S. nupta  in having a retrolateral tibial apophysis with a more or less truncated distal margin and a long dorsolateral process ( Jocqué & Bosmans, 1989: figs. 14,15,17,18), but differ from the former by the shorter and curved tip of the median apophysis ( Figs. 8, 9View FIGURE 8 – 10) and from the latter by the shorter, dorsolateral process of the RTA ( Figs. 9, 10View FIGURE 8 – 10). The abdominal pattern is also different ( Fig. 7View FIGURE 7; Jocqué & Bosmans, 1989: figs. 13, 16). Females are similar to those of S. arboccoae  in having an arrow­like abdominal dorsal median stripe, but differ by their genitalia ( Figs. 11–12View FIGURES 11 – 12): a larger epigynum, with the middle field quadrangular (as in S. nupta  ; Jocqué & Bosmans, 1989: fig. 19) but differing in having a deep posteroventral concavity.

Description (male holotype): Total length 10.59. Carapace length 5.89, width 4.69. Sternum length 2.32, width 1.80. Chelicerae length 1.92; clypeus height 1.08. Legs, length of articles: femora: I 4.72, II 4.00, III 3.60, IV 4.40; patellae: I 2.28, II 2.20, III 1.64, IV 1.92; tibiae: I 3.68, II 3.08, III 2.40, IV 3.16.; metatarsi: I 2.96, II 2.48, III 1.76, IV 2.64; tarsi: I 2.00, II 1.64, III 1.32, IV 1.48. Macrosetae: Tibia II, ventral r 1 ap spine. Metatarsi: I ventral 0­ 0­2 ­ 2 ­ 2 ­ 2 cusps; II, ventral 0­ 0­2 ­ 2 ­ 2 ­ 2 cusps plus 2 ap spines; III and IV, 4 ap plus 4 ap black cusps, just before each distal spine. Remaining articles devoid of macrosetae. Carapace cuticle granulated, dark reddish brown with median lighter reddish brown stripe, with white pubescence from the ocular area to the back ( Fig. 7View FIGURE 7). Clypeus without white hairs or lighter band; wide triangular chilum with several hairs. Sternum, labium and endites reddish brown. Legs: reddish brown, femora darker than other segments, with annular light bands around their bases (more diffused on two anterior pairs). Abdomen dorsally brown with one median and two lateral lighter stripes with whitish hairs; a wide trapezoid spot also with whitish hairs above the spinnerets. Abdominal sigillae (marking apodemes) orangish, two pairs on dorsum, on both sides of median stripe, one pair above pedicel, and one lateral above each pulmonary spiracle. Venter brown with two oblique yellowish wide bands from epigastric fold towards spinnerets. Pre­epigastric area brown at middle; posterior margin of epiandrum orange, sclerotized, slightly protruding, with two yellowish oval spots in front.

Female (ca. 5 km from Khe Bu): Total length 13.37. Carapace length 6.22, width 4.85. Sternum length 2.48, width 1.68. Chelicerae length 1.88; clypeus height 0.90. Legs, length of articles: femora: I 4.40, II 3.88, III 3.48, IV 4.20; patellae: I 2.32, II 2.24, III 2.12, IV 2.24; tibiae: I 3.28, II 2.92, III 2.08, IV 3.16.; metatarsi: I 2.52, II 2.32, III 1.68, IV 2.68; tarsi: I 1.48, II 1.60, III 1.28, IV 1.44. Macrosetae: Tibia II, ventral r 1 ap spine. Metatarsi: I ventral 0­ 0­2 ­ 2 ­ 2 ­ 2 cusps plus 2 ap spines; II, ventral = I but cusps asymetrical (three pairs on left, four on right, not well paired); III –IV, ventral 4 ap spines plus 3 ap black cusps, just before each distal spine except the most retrolateral. Remaining articles devoid of macrosetae. Color as in male, but dorsal median stripe of abdomen fused with posterior spot, forming an arrow (as in S. arboccoae  – Jocqué & Bosmans 1989: fig. 6 –). Abdominal sigillae as in the male. Epigynum ( Fig. 11View FIGURES 11 – 12): Middle field quadrangular in ventral view, with deep posteroventral concavity. Vulva ( Fig. 12View FIGURES 11 – 12): Copulatory ducts coiled, broadened close to spermatheca, spermathecae oval, fertilization ducts on posterior margin. Four simple tracheae.
