description: Description of Yoshiobodes (Yoshiobodes) neotrichorostralis sp. nov.
(Figures 9–12)
Diagnosis. Body size: 298–381 × 166–215. Surface of centrodorsal part of prodorsum and notogaster foveolate. Lamellae and prodorsum with one pair of transverse ridges, slightly separated medially. Rostrum with three pairs of additional setae. Sensilli narrowly spindle-form, with strong spines unilaterally. Four pairs of genital setae present.
Description. Measurements. Body length: 365 (holotype), 298–381 (four paratypes); notogaster width: 182 (holotype), 166–215 (four paratypes).
Integument. Body brown, covered by microgranular cerotegument (diameter of granules less than 1). Surface of body, femora and trochanters III, IV foveolate (diameter up to 14 on prodorsum and subcapitular mentum; up to 20 on notogaster, ventral side and legs), often forming a reticulate ornamentation.
Prodorsum. Rostrum rounded (visible in dorso-frontal and frontal view). Lamellae and prodorsum with one pair of well developed transverse ridges, slightly separated medially, located anteriorly to interlamellar setae. Translamella weakly developed. Rostral setae (14–16) setiform, thin, slightly barbed. Rostrum with three additional setae (pr 1– pr 3, 14–16) on each side, setiform, straight, barbed. Lamellar setae (24–28) thickened, barbed. Interlamellar (16–20) setae phylliform, with small barbs. Sensilli (49–57) narrowly spindle-form, with strong spines unilaterally. Exobothridial setae and their alveoli absent. Tutoria long, with knife-like cusp comprising about one-fifth of fused portion of tutorium.
Notogaster. Prodorsum and notogaster separated by well developed furrow. Anterior notogastral margin straight. Humeral regions each with a indistinct concavity. Fifteen pairs of notogastral setae (16–20) phylliform, with small barbs. Lyrifissures and opisthonotal gland openings not visible under the cerotegumental layer.
Gnathosoma. Subcapitulum longer than wide (69–77 × 65). Subcapitular setae setiform, slightly barbed; h (12–14) little longer than m and a (both 10–12). Adoral setae absent. Palps (49) with setation 0–2–1–3–8(+ω). Solenidion long, thickened, blunt-ended, not attached to eupathidium, pressed to surface of palptarsus. Chelicerae (82) with two barbed setae; cha (22–24) longer than chb (12–14). Trägårdh’s organ distinct.
Epimeral and lateral podosomal regions. Epimeral setal formula 3–1–3–3. Epimeral setae short (4–6), thin, smooth. Pedotecta I large, scale-like (in lateral view); pedotecta II widely triangular, rounded distally. Discidia triangular, blunt distally.
Anogenital region. Four pairs of genital, one pair of aggenital and two pairs of anal setae similar in length (6–8), thin, smooth. Three pairs of adanal setae (12) phylliform, barbed. Lyrifissures iad not visible under the cerotegumental layer.
Legs. Morphology and setation (Table 1) similar to Yoshiobodes hexasetosus sp. nov., but solenidia φ on tibia IV thickened (not dilated in median part), and setae l'' on femora I, II thickened (versus simple).
Material examined. Holotype (female) and one paratype (female): southern Vietnam, Lam Dong Province, Bi Dup – Nui Ba National Park, 12°11' N, 108°40' E, coniferous pine dominated forest, soil, 6–7.XII.2013, collected by Alexander E. Anichkin and Sergey G. Ermilov. Three paratypes (two females and one male): southern Vietnam, Lam Dong Province, Bi Dup – Nui Ba National Park, 12°11' N, 108°40' E, low-stemmed deciduous forest, soil, 6–7.XII.2013, collected by Alexander E. Anichkin and Sergey G. Ermilov.
Type deposition. The holotype is deposited in the collection of the Zoological Institute of the Russian Academy of Sciences, St. Petersburg, Russia; three paratype are deposited in the collection of the Siberian Zoological Museum, Novosibirsk, Russia; one paratype is deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia.
Etymology. The specific name neotrichorostralis refers to the presence of three additional prodorsal setae on the lateral sides of the rostrum.
Remarks. The new species differs from other known species of the subgenus by the presence of three pairs of additional setae on the prodorsum and foveolate ornamentation on the notogaster (versus additional setae absent, surface tuberculate).
