description: <i>Epeirotypus dalong</i> Miller, Griswold &amp; Yin, sp. n. urn:lsid:zoobank.org:act: 1E0E0249-EBA3-4A46-A5D1-B1E4D50426C4 Figs 2, 3 A-B, 94 <b>Material Examined.</b> Holotype: CHINA: Yunnan: Fugong Co., 4.5 km N Aludi Village, 22.1 km N Fugong, 26.10829°N, 98.87162°E, 1250 m, 23 April 2004, in stream gorge, C. Griswold, CGY07 (CASENT 9020742, HNU), 1 ♁. Paratypes: [same data as holotype] (CASENT 9029330, HNU), 1 &amp;female;, 4 juvs; [same data as holotype] (CASENT 9020743, CAS), 1 &amp;female;, 4 juvs. <b>Etymology.</b> Formed from the Chinese words for big (dà) and hole (lóng), referring to the form of the epigynal atrium. <b>Diagnosis.</b> Males distinguished from other described <i>Epeirotypus</i> species by the tuberculate texture of the mesal lobe of the tegulum (Fig. 2C); females distinguished by the more open atrium of the epigynum (Fig. 3B; compare to Coddington 1986a: figs 46, 57) and by the central interruption of the transverse submarginal groove (Fig. 3A; groove continuous across center in other described <i>Epeirotypus</i> species, Coddington, 1986a: figs 50, 58). Further distinguished from <i>E. brevipes</i> (Coddington, 1986a: fig. 47) by the lack of humps on the abdomen. Only two <i>Epeirotypus</i> species are described, both from the Neotropics. Coddington (1986a) noted the existence of several undescribed species including possibly some from Malaysia; this is the first formally described <i>Epeirotypus</i> from Asia. <b>Description.</b> Carapace tan, brown from thoracic region to ocular region. Sternum orange with broad dark brown margins. Legs orange, dark brown distally at joints, especially tibiae. Abdomen tan with brown or dark gray patches and silver spots. Male palp: Palpal patella with strong sinuous macroseta (Fig. 2C). Palpal tibia with two trichobothria. Paracymbium elongate with curve near base (Fig. 2B). Tegulum large, mesal lobe tuberculate (Fig. 2C). Median apophysis lightly sclerotized, with fine distoventral projection (Fig. 2A). Conductor a complex of sclerotized and membranous structures enveloping thick embolus for most of its length (Fig. 2A). Vulva: Epigynum a deep atrium with pair of humps on posterior margin leading to transverse grooves (Fig. 3B). Male (CASENT 9020742): Total length 1.92, carapace 0.87 long, 0.84 wide, clypeus 0.20, sternum 0.47 long, 0.48 wide, coxa IV separated by 1.54 times their width. Posterior median eyes separated by less than half their diameter. Macrosetae: Leg I: femur p1, r1, patella d1, tibia d2, p1, r1; Leg II: patella d1, tibia d2, r1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.17; TmII: 0.17; TmIII: 0.17. Leg measurements: see Appendix A. Female (CASENT 9020743): Total length 2.00, carapace 0.85 long, 0.83 wide, clypeus 0.18, sternum 0.49 long, 0.47 wide, coxa IV separated by 1.52 times their width. Posterior median eyes separated by less than a quarter their diameter. Macrosetae as in male. Metatarsal trichobothria: TmI: 0.15; TmII: 0.16; TmIII: 0.19. Leg measurements: see Appendix A.
