Hahnia ngai Rivera-Quiroz & Petcharad & Miller 2020, sp. nov.
No full textHahnia ngai sp. nov. urn:lsid:zoobank.org:act: F9A7FE4B-77C4-4D9B-AFDB-A2FC6F5E0739 Figs 4, 6 a–c Diagnosis Hahnia ngai sp. nov. can be easily separated from other members of this genus by the simplified female genitalia. Copulatory ducts show only slightly swollen areas with glandular insertions (Figs 4g, 6 b–c) but do not form a receptacle or secondary spermathecae (as seen in Figs 5g, 6 e–f). Etymology The species epithet is a derivation of the Thai ngai (simple), in reference to the relatively simple vulva without the well-formed secondary spermathecae commonly seen in other species of Hahnia.

Hexamatia seekhaow Rivera-Quiroz & Petcharad & Miller 2020, gen. et sp. nov.
No full textHexamatia seekhaow gen. et sp. nov. urn:lsid:zoobank.org:act: 1D1D0DE7-8A2A-4469-8867-666F9AD6EAEB Figs 2–3 Diagnosis Hexamatia seekhaow gen. et sp. nov. greatly resembles H. senaria gen. nov. but can be distinguished by the bifurcated PA and having a slightly shorter RTA with a blunter tip (Figs 2f, 3 d–e; Zhang et al. 2011: figs 21a–d, 22). Another putative difference is the presence of denticles in the distal portion of the RTA; these are not mentioned nor illustrated for H. senaria gen. nov. Etymology The species epithet is a derivation of the Thai seekhaow (white); refers to the lack of color on the body of the holotype of this species. Type material Holotype THAILAND • ♂; Chiang Mai Province, Doi Suthep National Park; 18º48.502′ N, 98º53.528′ E; 1409 m a.s.l.; 24–28 Jul. 2018; Booppa Petcharad, Jeremy Miller and F.

It can be separated from other six-eyed hahniids by the following combination of characters: from <i>Amaloxenops</i> Schiapelli & Gerschman, 1958 by having a backward curved RTA without twists, and presence of PA on the pedipalp patella and MA on the bulb; from <i>Intihuatana</i> Lehtinen, 1967 by having an unbifurcated RTA, a shorter and bifurcated PA, and presence of MA; and from <i>Scotospilus</i> Zhang, Li & Pham, 2013 by the comparatively short RTA, bifurcated PA and presence of MA.</p> Etymology <p> The genus name is formed from two Greek roots: <i>hexa</i> (six) and <i>mati</i> (eye). It refers to the number of eyes present in this genus, one of its diagnostic characters. The gender is feminine.</p> Composition <p> <i>Hexamatia seekhaow</i> gen. et sp. nov. and <i>Hexamatia senaria</i> (Zhang, Li & Zheng, 2011) gen. nov., based on the original description and illustrations.</p> Distribution <p> <i>Hexamatia seekhaow</i> gen. et sp. nov. is known from Chiang Mai, Thailand; and <i>Hexamatia senaria</i> gen. nov. from Yunnan, China (Fig. 8).</p>Published as part of <i>Rivera-Quiroz, Francisco Andrés, Petcharad, Booppa & Miller, Jeremy A., 2020, First records and a new genus of comb-tailed spiders (Araneae: Hahniidae) from Thailand with comments on the six-eyed species of this family, pp. 51-69 in European Journal of Taxonomy 724</i> on page 56, DOI: 10.5852/ejt.2020.724.1157, <a href="http://zenodo.org/record/4298074">http://zenodo.org/record/4298074</a>
Savarna miser Huber & Petcharad & Bumrungsri 2015, comb. nov.

New synonymy. Spermophora miser – Huber 2005: 85 (considered as incertae sedis). Savarna baso – Huber 2005: 78, Fgs 127–128, 135–137 (Ƌ). JustiFcation of synonymy The holotype of S. baso was compared directly with fresh specimens of S. miser originating from the type locality. The males were found to be identical in all relevant genital structures (cf. Figs 77–80). Diagnosis Easily distinguished from known congeners by morphology of male palp (strongly curved ventral trochanter apophysis; shapes of procursus and bulbal process; Figs 81–82), and by female external and internal genitalia (posterior margin of epigynal plate with pair of semicircular extensions; without median process as in S. kraburiensis; pore plates contiguous; Figs 34–35, 38–39, 84–85). From most species (except S. tessellata) also distinguihsed by absence of black marks laterally on carapace (Figs 74, 75); from S. tessellata also by paired male clypeus apophyses (unpaired in S. tessellata) and less elongated male palpal tibia. Type material Spermophora miser. MALAYSIA: Unknown number of female syntypes and two juveniles, Selangor, Kuala Lumpur, Batu Caves [3°14.3’ N, 101°41.0’ E], “ in Fimsy webs in wall crevices ”, Nov. 1930 – Jan. 1931, W.S.

Jacobson leg., but see Addendum; SMF (RII/13853/122), examined (in 2004 and again for the present study).

Laufs leg. (SMF). Redescription Male (Batu Caves, type locality) MEASUREMENTS. Total body length 2.2, carapace width 1.1. Leg 1: 22.2 (5.5 + 0.4 + 5.4 + 8.8 + 2.1), all other legs detached; tibia 1 L/d: 47. Distance PME-PME 185 µm, diameter PME 105 µm, distance PME-ALE 35 µm; AME absent. COLOR. Carapace pale ochre; ocular area and clypeus dark brown; sternum black; legs light brown, with darker rings on femora (subdistally) and tibiae (proximally and subdistally); abdomen pale gray, with dark subcuticular marks lying above deeper white marks, with distinct ventral pattern consisting of three interconnected black marks. BODY. Habitus as in Fig. 74; ocular area elevated, each triad on short hump directed toward lateral; carapace with deep median furrow; clypeus with pair of rounded processes at rim, similar to S. kaeo sp. nov. but smaller (cf. Fig. 20); sternum wider than long (0.78/0.54), unmodiFed. Chelicerae as in Fig. 83, with pair of lateral processes, directed slightly toward posterior; without stridulatory ridges. PALPS. As in Figs 81–82; coxa unmodiFed; trochanter with small retrolateral and ventral processes and distinctive long ventral apophysis, proximally attached to femur, distally strongly curved; procursus distally complex, with distinctive membranous and sclerotized elements; bulb with large proximal sclerite, with single complex process (Fig. 79) apparently containing sperm duct. LEGS. Without spines; with vertical hairs in higher than usual density on all tibiae; without curved hairs; retrolateral trichobothrium on tibia 1 at 9%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsal pseudosegments indistinct, about 15 visible distally on tarsus 1. Male (variation) The holotype of S. baso is strongly bleached (cf. Fgs 127–128 in Huber 2005), but the distinctive male genital structures are indistinguishable from those of males from the type locality (Figs 77–80). In the fresh material from the type locality, all bulbs are rotated away from their natural position, which explains the differences between the palps of S. baso illustrated in Huber (2005) and the palps illustrated herein. Female In general similar to male; eye triads closer together (PME-PME distance: 150 µm); clypeus unmodiFed; leg tibiae with usual low density of vertical hairs. Tibia 1: 5.4 (missing or detached in other specimens). Epigynum slightly protruding (Fig. 35), with wide transversal sclerotized plate with pair of semicircular posterior extensions (Figs 34, 38, 84); internal genitalia as in Figs 39 and 85, pore plates contiguous (whether the sclerotized bars extending toward posterior are also provided with pores is not clear).
