  • Lanceoppia trapezoides Ermilov, Sergey G., 2015, Zootaxa 4007: 189-193.


Diagnosis. Body size: 390–415 × 199–232. Rostral setae longer than lamellar and interlamellar setae; all barbed. Bothridial setae fusiform, heads similar in length to stalks. Costulae well visible, arch-formed in posterior parts. Ten pairs of notogastral setae present (including c). Setae la inserted antero-laterally to lm. Epimeral and anogenital setae slightly or indistinctly barbed.


Description.Measurements. Body length: 398 (holotype, male), 390, 415 (2paratypes, females); notogaster width: 232 (holotype), 199, 215 (2paratypes). Integument. Body color light brownish. Body surface smooth, but lateral sides of prodorsum near acetabula I– II with tuberculate cerotegument (diameter of tubercles up to 2). Prodorsum. Rostrum elongate triangular, narrowly rounded. Rostral (41–45), lamellar (32–36) and interlamellar (32–36) setae setiform, barbed. Exobothridial setae minute (2–4), thin, smooth. Bothridial setae (41) fusiform, heads similar in length to stalks, pointed or rounded distally, slightly barbed. Costulae and transcostulae distinctly developed. Costulae arch-formed in posterior parts. Longitudinal rows of muscle sigillae present anteriad to bothridia. Interbothridial region without tubercles, with 3 pairs of rounded muscle sigillae. Postbothridial tubercles present, slightly visible, broadly rounded. Notogaster. Anterior border convex medially. Ten pairs of notogastral setae present; c (6–8) needle-form, other setae of medium size (49–57), setiform, barbed. Setae la inserted antero-laterally to lm. Lyrifissures and opisthonotal gland openings well visible. Gnathosoma. Subcapitulum longer than wide (77–82 × 49–53). Subcapitular setae setiform, slightly barbed; m and h (both 16–20) longer than a (12–16). Two pairs of adoral setae (4) thin, smooth. Palps (57) with setation 0–2 – 1–3 – 8 (+ω); their solenidion as long as half of palptarsus, thickened, blunt-ended, pressed to the surface, reaching the level insertion of basal part of seta acm. Chelicerae (73–77) with 2 setiform, barbed setae; cha (24, longer than chb (14). Trägårdh’s organ tapered.

Epimeral and lateral podosomal regions. Apodemes (1, 2, sejugal, 4) well visible. Epimeral setae setiform, slightly barbed; medial setae 1 a, 2 a, 3 a (14–16) shorter than other (28–32). Pedotecta I represented by small laminae. Discidia well developed, triangular. Anogenital region. Six pairs of genital (g1, g6, 14; g2 – g5, 10), 1 pair of aggenital (24–28), 3 pairs of adanal (24– 28), 2 pairs of anal (20–24) setae setiform, indistinctly barbed. Adanal lyrifissures distinct, slightly distanced from anal aperture. Legs. Claw of each leg smooth, with small, ventro-basal tubercle. Formulas of leg setation and solenidia: I (1– 5 – 2–4 – 20) [1–2 – 2], II (1–5 – 2–4 – 16) [1 – 1–2], III (2–3 – 1–3 – 15) [1 – 1 –0], IV (1–2 – 2–3 – 12) [0–1 –0]; homology of setae and solenidia indicated in Table 1. Setae p setiform on tarsi I, and very short, conical on tarsi II–IV. Famuli (ɛ) stick-shaped, inserted posteriorly to solenidia ω 1.

Materials Examined

Material examined.Holotype (male) and two paratypes (two females): New Zealand, South Island, Central Otago, The Remarkables, 45 ° 3 ' 38 ''S, 168 ° 48 ' 43 ''E, 1867 m a.s.l., in the soil and debris under Dracophyllum muscoides cushion, 19 February 2014, collected by M. Minor. Type deposition. The holotype and one paratype are deposited in the New Zealand National Arthropod Collection, Auckland, New Zealand; one paratype is deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia.


Etymology. The specific name trapezoides refers to the lamellae and translamella forming trapezoid structure on prodorsum.


Remarks.Lanceoppia (Baioppia) trapezoides sp. nov. is morphologically most similar to L. (B.) moritzi Hammer, 1968 from New Zealand in having fusiform bothridial setae and well-developed costulae, and in location of notogastral setae la (antero-laterally to lm). However, it differs from the latter by the larger body length (390– 415 vs. 280), by presence of notogastral setae c (vs. represented by alveoli), and by long interlamellar setae (vs. short).
