Ordo: Araneae
Familia: Mysmenidae
Genus: Microdipoena
Name
Microdipoena huisun Zhang & Lin, 2023 sp. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype ♀ and paratype 4♀ (NHMSU-TW03), China: Taiwan Province, Nantou County, Huisun Forest Farm (24°05.279'N, 121°02.078'E; 788 m elev.), 1.VII.2013, G. Zheng leg.
Etymology
The specific name is derived from the type locality; noun in apposition.
Diagnosis
This new species differs from other species except for M. gongi, M. ogatai, and M. yinae by the nearly spherical spermathecae and having a small scape rather than a long, soft, membranous one (cf. Figs 10E, F, 13C, 14F, 17C). It can be distinguished from M. gongi, M. ogatai, and M. yinae by the nearly spherical spermathecae and the narrower posterior sclerotized area of copulatory ducts (cf. Figs 10F, 9F, 19H and Ono 2007[1]: fig. 70).
Description
Female (holotype): Total length 0.76. Carapace 0.28 long, 0.29 wide, 0.28 high. Clypeus 0.07 high. Sternum 0.24 long, 0.19 wide. Abdomen 0.48 long, 0.48 wide, 0.50 high. Length of legs: I 0.94 (0.30, 0.08, 0.22, 0.16, 0.18); II 0.92 (0.32, 0.08, 0.22, 0.14, 0.16); III 0.70 (0.22, 0.08, 0.14, 0.12, 0.14); IV 0.94 (0.24, 0.08, 0.24, 0.18, 0.20).
Somatic characters
(Fig. 10A–C). Coloration: carapace nearly silver-brown centrally, black marginally. Ocular base black. Chelicera, endites yellow, labium silver-brown, sternum pale yellow with four symmetrical black spots. Legs brown-black. Abdomen black with multiple symmetrical white spots dorsally, black with symmetrical white and yellow spots ventrally. Prosoma: carapace nearly pear-shaped in dorsal view. Cephalic part unraised. Sternum triangular, covered with sparse setae. Legs: covered with setae and bristles. Femurs I and II with sclerotized femoral spot. Abdomen: nearly oval in dorsal view, covered with sparse setae.
Epigyne (Fig. 10D–F): scape nodular shape, very small. Copulatory duct membranous, coiled under the spermathecae. Paired spermathecae nearly globose, separated by nearly 3× its diameter. Fertilization ducts membranous, inconspicuous.
Male. Unknown.
Distribution
