description: Ledermuelleriopsis indiscretus sp. nov.
Holotype. Female (Figure 15). Length of body 313 (300–320), width 180 (160–195).
Dorsum. Prodorsal shield with four pairs of setae (vi, ve, sce and sci) and a pair of eyes. Metapodosomal shield with three pairs of setae (c 1, d 1, d 2), opisthosomal shield with three pairs of setae (e 1, e 2, f 1) and suranal shield with two pairs of setae (h 1,2). Metapodosomal and opisthosomal shields incompletely separated. Dorsal shields covered with oval patterns, evident laterally, each oval dimple contains 12–17 vacuoles, different in size and shape. Fossettes on dorsal shields as illustrated. Dorsal setae with numerous tight spinules. Dimensions of setae as follows: vi 15 (13–18); ve 13 (10–15); sci 15 (13–20); sce 18 (15–23); c 1 20 (18–25); c 2 23 (20–27); d 1 18 (15–20); d 2 15 (10– 15); e 1= e 2 18 (15–20); f 1 28 (23–30); h 1 13 (10–15); h 2 15 (10–18); vi-vi 35 (30–40). Distances between setae: ve-ve 70 (60–78); vi-ve 25 (20–33); sci-sci 110 (97–115); ve-sci 20 (15–25); sce-sce 135 (130–140); sci-sce 35 (27–43); c 1 -c 1 65 (60–67); c 1 -d 1 45 (40–53); d 1 -d 1 63 (60–67); c 1 -d 2 50 (40–58); d 2 -d 2 150 (140–165); d 1 -d 2 50 (45–58); e 2 -e 2 115 (110–118); e 1 -e 1 70 (60–75); e 1 -e 2 40 (35–43); f 1 -f 1 73 (65–85); e 1 -f 1 35 (30–45); e 1 -f 2 73 (70–85); h 1 -h 1 30 (25– 37); h 2 -h 2 70 (65–75); h 1 -h 2 20 (18–27).
Venter. Humeral shields in ventrolateral position, bearing setae c 2, with small spinules, more slender than dorsal body setae, patterns on humeral shields similar to those of dorsal shields. Coxisternal shields completely fused, reticulate, except central region of posterior coxisternal shield. Coxisternal shields bearing three pairs of setae (1a, 3a, and 4a). Three pairs of setae (ag 1-3) on aggenital shield. Anogenital covers bearing three pairs of pseudanal setae (ps 1-3).
Legs. Leg I 200 (180–210), leg II 175 (170–185), leg III 150 (143–155), leg IV 190 (175–198). Chaetotaxy of leg segments as follows: coxae 2–2–2–2, trochanters 1–1–2–1, femora 6–4–3–2, genua 4(κ)–4(κ)–1–1, tibiae 7(ϕ,ϕρ)–6(ϕρ)–6(ϕρ)–6(ϕρ), tarsi 14(ω)–10(ω)–8(ω)–7. Genua I and II with solenidion κ.
Gnathosoma. Chelicera 43 (35–40), palp 85 (80–90). Subcapitulum with two pairs of adoral setae (ro 1,2) distally and two pairs of subcapitular setae (m and n) proximally.
Male and other immature stages. Unknown.
Etymology. The specific name indiscretus means undivided in Latin, referring to the metapodosomal and opisthosomal shields being incompletely divided.
Type materials. Holotype Ƥ, 2 paratypes ƤƤ from moss on soil, 40°22'88'' N, 37°21'46'' E, 519 m, between Koyulhisar-Reşadiye, 17 V 2009; ZMAU.
Remarks. This new species resembles Ledermuelleriopsis plumosus Willmann, 1951 and L. ayyildizi Doġan, 2004 in general appearance. It can be easily distinguished from these species by the metapodosomal and opisthosomal shields being incompletely separated. This species is also similar to L. bisetalis Doġan, 2004 in that the metapodosomal and opisthosomal shields are incompletely separated, but in the new species the dorsal body setae are homeomorphic whereas they are heteromorphic in L. bisetalis and the ventral surfaces in these two species have dissimilar patterns.
In L. bisetalis and L. indiscretus sp. nov., the hysterosomal shield is incompletely divided. We consider them intermediate species between the genera Ledermuelleriopsis and Eustigmaeus, and currently regard them better placed in Ledermuelleriopsis.

Ledermuelleriopsis bisetalis Doġan, 2004b: 142; 2007: 17; Erman, Özkan, Ayyıldız & Doġan, 2007: 8.
Materials examined. 2 ƤƤ from litter under Juniperus sp., Pinus sp., Picea sp. and Rosa canina, 40°15'46'' N, 38°50'18'' E, 1820 m, Alucra, 22 IX 2007; 3 ƤƤ from decayed bark of tree, 40°15'45'' N, 38°50'17'' E, 1816 m, Şiran, 10 V 2008; 1 Ƥ from moss on soil, 40°14'59'' N, 38°57'10'' E, 1592 m, between Şiran and Alucra, 29 IX 2008; ZMAU.
Distribution. Turkey (Doġan 2004b, 2007; Erman et al. 2007).
Remarks. This species is known only from Turkey and can be easily distinguished from others by having heteromorphic dorsal body setae, the differing dorsal and ventral patterns, and the metapodosomal and opisthosomal shields being incompletely separated. Our specimens identified as Ledermuelleriopsis bisetalis exhibit all the characters of the type specimens.

Distribution. Turkey (Doġan 2004b, 2007; Akyol 2007; Erman et al. 2007).
Remarks. This species is known only from Turkey and is similar to Ledermuelleriopsis plumosus Willmann, 1951 in general appearance, but in this species humeral setae c 2 are robust and are similar to the dorsal body setae. Our specimens resemble Ledermuelleriopsis ayyildizi in all respects except the ventral surface is faintly reticulated in some specimens.
