Type deposition

The holotype is deposited in the collection of the Senckenberg Museum of Natural History, Görlitz, Germany; four paratypes are 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: 570–615. Body surface densely microgranulate. Rostrum rounded. Lamellar and sublamellar lines divergent mediodistally; lamellar line directed to insertion of rostral seta. Rostral seta medium-sized, setiform, slightly barbed; lamellar seta short, setiform, roughened; interlamellar seta minute, needleform; bothridial seta long, lanceolate, barbed. Dorsosejugal porose area elongate oval. Dorsosejugal suture complete. Four pairs of notogastral porose areas: Aa boomerang-like; A1 and A2 oval; A3 oval or elongate oval. Median pore present in both genders. Epimeral and anogenital setae minute, needleform. Circumpedal carina medium-sized. Postanal porose area long, band-like. Leg solenidion on tibia IV inserted in anterior part of the segment.

Description

Measurements – Body length: 600 (holotype), 570, 600 (male paratypes), 615, 615 (female paratypes); notogaster width: 413 (holotype), 405, 420 (male paratypes), 427, 435 (female paratypes).

Integument – Body color yellowish brown. Body surface densely microgranulate.

Prodorsum – Rostrum rounded, sometimes narrowed. Lamellar and sublamellar lines divergent mediodistally; lamellar line slightly thickened, straight, directed to insertion of rostral seta; sublamellar line thin, curving backwards at ventral end. Rostral seta (49–54) setiform, slightly barbed; lamellar seta (19–26) setiform, roughened, thinner than rostral seta; interlamellar seta (7) needleform; bothridial seta (90–101) with long stalk and short, lanceolate, barbed head. Dorsosejugal porose area elongate oval (34–37 × 7–11), located posterolaterally to insertion of interlamellar seta. Dorsophragma elongated.

Notogaster – Dorsosejugal suture complete, slightly convex medially. Ten pairs of notogastral setae represented by setal alveoli. Four pairs of porose areas observable; Aa boomerang-like (length of medial transverse part: 67–82; length of lateral longitudinal part: 56–71; width: 7–19); A1 (22–30 × 15–19) and A2 (22–37 × 19–22) oval; A3 oval or elongate oval (34–60 × 15–22); Aa located near to pteromorphal hinge and anterior to setal alveolus. Median pore present in both genders, represented by one large fovea located posterior to the virtual line connected porose areas A1. Opisthonotal gland opening and all lyrifissures distinct: gla located laterally to A1; im anteriorly to A1; ip between p 1 and p 2; ih and ips usually close to each other, anteriorly to p 3.

Gnathosoma – Size of subcapitulum: 146–150 × 116–131; subcapitular setae a (26–30) and m (19–22) setiform, slightly barbed; h (7) needleform; both adoral setae (13–15) setiform, barbed. Length of palp: 116–120; setation: 0-2-1-3-9(+ω); postpalpal seta (7) spiniform, smooth. Length of chelicera: 161–165; setae (cha: 52–56; chb: 34–37) setiform, barbed.

Epimeral and lateral podosomal regions – Epimeral setal formula: 1-0-1-3; all setae (3b: 15; 1a, 4a, 4b, 4c: 7) needleform. Circumpedal carina medium-sized, directed to insertion of seta 3b, but distinctly not reaching it.

Anogenital region – Anogenital formula: 6-1-2-3; genital (g 1: 15; others: 7), aggenital (7), anal (7), and adanal (7) setae needleform; anterior edge of genital plate with two setae; aggenital seta located posterolaterally to genital aperture; adanal setae ad 1 and ad 2 posteriorly, ad 3 laterally to anal plate; distance ad 1 – ad 2 shorter than ad 2 – ad 3. Adanal lyrifissure oblique, located close and anterolaterally or laterally to adanal seta ad 3. Postanal porose area long (266–281 × 11–15), band-like. Ovipositor is typical for Galumnidae (see Ermilov 2010); length of blade: 116; length/width of distal section (beyond middle fold): 146/75; each of the three blades with four smooth setae: ψ 1 ≈ τ 1 (41) rod-like; ψ 2 ≈ τa ≈ τb ≈ τc (26) thinly thorn-like; six coronal setae (5) spiniform.

Legs – Median claw distinctly thicker than lateral claws; all claws slightly barbed on dorsal side. Porose area on femora I–IV and on trochanters III, IV poorly visible; proximoventral porose area on tarsi and distoventral porose area on tibiae not observable. Formulas of leg setation and solenidia: I (1-4-3-4-20) [1-2-2], II (1-4-3-4-15) [1-1-2], III (1-2-1-3-15) [1-1-0], IV (1-2-2-3-12) [0-1-0]; homology of setae and solenidia indicated in Table 1; famulus inserted between seta ft” and solenidion ω 2; seta s on tarsus I eupathidial, inserted between paired setae u and a; solenidion on tibia IV inserted in anterior part of the segment.

Remarks

Distinctive characters of the new species compared with other members of Galumna (Neogalumna) can be found in the identification key given below.

Etymology

The species name paraharrysmiti refers to the similarity between the new species and G. (N.) harrysmiti Ermilov, 2016.
