Diagnosis — Body size: 166–232 × 597–647. Body surface punctate, anal plates and medioposterior part of notogaster foveolate. Rostral and lamellar setae long, setiform, slightly barbed. Interlamellar and 10 pairs of notogastral setae of medium size, phylliform, slightly barbed. Bothridial setae long, fusiform or clavate, barbed. Lateral and medial prodorsal and notogastral condyles tubercle-like, simple. Epimeral setal formula 2-0-2-3. Epimeral and genitoaggenital setae setiform, slightly barbed. Adanal and anal setae phylliform, slightly barbed. Adanal lyrifissures distanced from anal aperture. Leg genua III and IV without seta l’. Setae u setiform on all leg tarsi.

Description — Measurements – Body length: 498 (holotype: male), 464–647 (seven paratypes: three females and four males); notogaster width: 182 (holotype), 166–232 (seven paratypes). Length/width ratio 2.7–2.8. Females larger than males: 597–647 × 199–215 versus 464–514 × 166–182.

Integument ( Figs 1a, 1b View Figure 1 , 2b View Figure 2 , 3b View Figure 3 , 4a View Figure 4 , 5a View Figure 5 , 6a View Figure 6 , 7c View Figure 7 ) – Body color light brown, but legs, apodemes and anterior part of chelicerae dark brown. Body covered by layer of colorless, gel-like cerotegument. Body surface punctate. In addition, anal plates and medioposterior part of notogaster (between setae lm and h 1) sparsely foveolate (diameter of foveolae up to 4 and

2, respectively). Costulae partially foveolate. Lateral parts of body (between bothridia and acetabula I–III) without tubercles. Antiaxial side of all leg femora and trochanters III, IV with microgranules.

Prodorsum ( Figs 1a View Figure 1 , 2a View Figure 2 , 5 View Figure 5 a-c, 7a, 7b) – Rostrum broadly rounded. Anterior part of prodorsum with strong transverse ridge. Costulae well developed, long, reaching bothridia basally and lamellar setae distally. Tutorial ridges and lateral carinae absent. Rostral (57–51) and lamellar (65–69) setae setiform, slightly barbed (poorly visible), curving and directed anteromedially. Interlamellar setae (24–32) phylliform, slightly barbed. Exobothridial setae (8–10) setiform, thin, smooth. Bothridial setae (length outside bothridia 65–73) with long, smooth stalk and shorter, fusiform or clavate, barbed head. Paired lateral and paired medial prodorsal condyles tubercle-like, located separately.

Notogaster ( Figs 1a, 1b View Figure 1 , 2a, 2b View Figure 2 , 5 View Figure 5 a-c, 6a, 7c) – Paired lateral and paired medial notogastral condyles tubercle-like, without fusions, located separately. Circumdorsal part of notogaster slightly depressed ( Figs 5a, 5b View Figure 5 ). Circumgastric sigillar band visible. Notogaster with 10 pairs (45–49) of phylliform, slightly barbed setae. Lyrifissures and opisthonotal gland openings distinct, ia located lateral to c, im and gla close to each other, lateral to lm, ip between p 2 and

p 3, ips and ih anterior to h 3.

Gnathosoma ( Figs 1b View Figure 1 , 2a View Figure 2 , 6a View Figure 6 ) – Generally, similar to L. murphyi . Subcapitulum longer

than wide (114–123 × 73–82). Subcapitular setae setiform, barbed, a (28–30) shorter than m and h (36–41). Adoral setae and their alveoli absent. Palps (73–77) with typical setation 0-2- 1-3-8(+ω). Postpalpal setae (6) spiniform, smooth. Chelicerae (135–139) with two setiform, barbed setae, cha (45–49) longer than chb (16–20). Trägårdh’s organ of chelicerae elongate triangular.

Epimeral and lateral podosomal regions ( Figs 1b View Figure 1 , 2a View Figure 2 , 5b View Figure 5 , 6a, 6b View Figure 6 ) – Apodemes I, II, III and sejugal apodemes distinct. Sternal apodeme not developed. Condyles of epimere IV well developed. Epimeral setal formula 2-0-2-3, setae setiform, slightly barbed, 1b (45–49) longer than 3b (36–41) and others (28–32); 1a, 2a, 3a and their alveoli absent. Pedotecta I and II represented by small lamina. Discidia tubercle-like.

Anogenital region ( Figs 1b View Figure 1 , 2a, 2b View Figure 2 , 5b View Figure 5 , 6a, 6b View Figure 6 ) – Aggenital lyrifissures not visible. Four pairs of genital (16–20) and one pair of aggenital (24–32) setae setiform, slightly barbed. Three pairs of adanal setae (36–41) narrowly phylliform, slightly barbed; ad 3 located lateral to anal plates and removed from them. Two pairs of anal setae (24–32) slightly dilated basally, with setiform mediodistal part, slightly barbed. Adanal lyrifissures transverse or diagonal, distanced from anal aperture, located anterior to insertions of adanal setae ad 3. Circumventral ridge well developed.

Legs ( Figs 3a, 3b View Figure 3 , 4a, 4b View Figure 4 , 5b View Figure 5 , 6a View Figure 6 ) – Claw of each leg strong, slightly barbed dorsally. Tarsi with one pair of very small teeth on dorsal side. Porose areas present on all femora and on trochanters III, IV (well visible in dissected specimens). Formulas of leg setation and solenidia: I (1-4-3-4-16) [1-2-2], II (1-4-3-3-15) [1-1-2], III (2-3-0-2-15) [1-1-0], IV (1-2-1-2-12) [0-1-0]; homology of setae and solenidia indicated in Table 1. Solenidia 1 and φ φ 2 on tibiae I, φ on

tibiae II, σ on genua I, II setiform, others bacilliform. Famulus of tarsi I short, erect, distally blunt, inserted posterior to solenidia. Setae u setiform on all tarsi.
