Type material

Holotype (female) and three paratypes (three females): Western Venezuela, Merida State, 2300 m a.s.l., 10 km E Tabay, sweeping in the cloud forest, 28.IV.1981 (L. Masner and Marsh).

Type deposition

The holotype is deposited in the collection of the Senckenberg Museum of Natural History, Görlitz, Germany; three paratypes are deposited in the collection of the University of Tyumen, Museum of Zoology, Tyumen, Russia . All specimens are preserved in 70% solution of ethanol with a drop of glycerol.

Diagnosis Body length: 750–840. Prodorsum, ventral side of body and lateral side of notogaster partially tuberculate; notogastral exuvial scalp with medium-sized, sparse foveolae. Rostral and lamellar setae medium-sized, setiform, stiff, roughened; interlamellar seta long, slightly thickened, barbed; bothridial seta comparatively short, clavate, barbed. Exuvial notogastral setae cpE, e 2 E short, setiform, stiff, slightly barbed; e 2 E ˃ cpE; true notogastral seta c 3 short, setiform, roughened; p 2, p 3 short, setiform, stiff, roughened; p 1, h 2, h 3 long, slightly thickened, barbed. Subcapitular seta a narrowly phylliform; m, h setiform. Epimeral and anogenital setae setiform, stiff, roughened.

Description

Measurements – Body length: 840 (holotype), 750–825 (paratypes); body width: 570 (holotype), 465–570 (paratypes).

Integument – Body color brown to dark brown. Body surface covered by gel-like cerotegument including dense microgranules. Prodorsum, ventral side of body and lateral side of notogaster partially tuberculate (diameter of tubercle up to 11). Notogastral exuvial scalp sparsely foveolate (diameter of foveola up to 11).

Prodorsum – Rostrum widely rounded. Rostral (75–90) and lamellar (94–105) setae setiform, stiff, roughened; interlamellar seta (255–281) slightly thickened, barbed, directed upwards; interlamellar seta thicker than rostral and lamellar setae; bothridial seta (86–94) clavate, barbed, with head slightly longer than stalk; exobothridial seta (19–26) setiform, slightly roughened.

Notogaster – Two pairs of exuvial notogastral setae remaining; cpE (52–56), e 2 E (67–71) setiform, stiff, slightly barbed. Six pairs of true notogastral setae (c 3, h 2, h 3, p 1, p 2, p 3) observable (other true setae under exuvium reduced); c 3 (30–34) setiform, roughened; p 2, p 3 (26–30) setiform, stiff, roughened; p 1 (165–187), h 2, h 3 (139–180) slightly thickened, barbed. Only lyrifissures ia, ips observable.

Gnathosoma – Subcapitulum size: 199–206 × 169–180; subcapitular seta a (34–37) narrowly phylliform, smooth or partially roughened mediodistally; m (60–67), h (52–56) setiform, roughened. Palp length: 94–97; setation: 0–2–1–3–6(+ω); postpalpal seta (15–19) spiniform, slightly roughened. Chelicera length: 225–236; both cheliceral setae (cha: 82–86; chb: 52–56) setiform, barbed.

Epimeral and lateral podosomal regions – Epimeral formula: 3–1–2–3; setae (1a, 1c, 2a, 4b: 37–45; 1b, 3b, 4a, 4c: 45–52; 3a: 67–79) setiform, stiff, roughened. Respiratory organs and channels not observed.

Anogenital region – Anogenital formula: 7–1–2–3; genital (g 5: 56–60; others: 30–37), aggenital (41–45), anal (49–56), and adanal (ad 1: 75–86; ad 2, ad 3: 30–34) setae setiform, stiff, roughened. Adanal lyrifissure oblique, located anteriorly to ad 3.

Legs – Claw of each leg strong, slightly barbed on dorsal side. Formulas of leg setation and solenidia: I (1–5–5–5–18) [1–2–2], II (1–5–5–5–15) [1–1–2], III (2–3–3–4–13) [1–1–0], IV (1–3–3– 4–13) [0–1–0]; homology of setae and solenidia indicated in Table 1; seta s on tarsi I, II and p’, p” on tarsus I eupathidial; some distal setae of all tarsi dilated in distal part.

Comparison

Hermannobates neotropicus sp. nov. is morphologically similar to the other Venezuelan species, H. intermedius Călugăr, 1990 , in having comparatively long, slightly thickened interlamellar and posterior notogastral setae p 1, h 2, h 3, and the presence of the head in the bothridial seta. However, the new species is distinguished from the latter by short, clavate bothridial seta (versus comparatively long, with slightly developed fusiform head).

Etymology The species name neotropicus refers to the place of origin, Neotropical region.
