description: Euphthiracarus oblongus sp. nov.
(Figs. 11–15)
Material examined: Holotype: adult (in alcohol, W-89-125), China: Hubei Province, Badong County (30°42'18.35"N, 110°17'52.28"E), Tiechanghuang Forestry Centre, from litter under broadleaf forest, 1500 m a.s.l., 12 Aug., 1989, leg. Yun-Qi Cui.
Etymology. The new specific name “ oblongus ” is from Latin and refers to the oblong head of sensilla.
Measurements: Holotype: Prodorsum: length 279, width 190, height 105, setae: ss 94, ro 80, in 150, le 95, ex 15, distance between setae: ro–ro 55, in–in 93, le–le 45, in–le 77, le–ro 70; notogaster: length 512, width 335, height 325; setae: c1 103, c2 100, c3 95, c p 100, d1 76, d2 70, e1 110, e2 70, h1 116, h2 75, h3 72, ps1 110, ps2 70, ps3 65; distance between setae: c1–d1 150, d1–e1 130, e1–h1 90, h1–ps1 77; ventral region: genitoaggenital plate 180×80, anoadanal plate 265×65.
Colour yellowish. Surface of body punctuate.
Prodorsum with two parallel lateral carinae on each side, upper carina longer and stronger than lower one; sensilla with long and narrow pedicel and oblong and smooth head; interlamellar and lamellar setae erect, covered with small and sparse spines in distal half; rostral setae thin, smooth and long, flagellate and directed inwards distally; comparative length: in>le> ss> ro>ex.
Notogaster with 14 pair of setae, relatively short, similar in shape to interlamellar setae, sparsely barbed in distal half; setae c1–3 remote from anterior border, setae c1 slightly more so than setae c2 and c3; vestigial setae f1 located anteriorly of setae h1; arrangement of opisthosomal glands and lyrifissures typical for genus.
Genital plates each with nine setae, g1–3 short and fine, located in progenital position, posterior six genital setae longer and thicker; two pairs of aggenital setae present, spiniform, nearly equally thick, setae ag2 slightly longer than ag1; setae an1 and an2 smooth and flagellate at distal end, setae an3 and adanal setae shorter, robust and covered with small and sparse spines in distal half; lyrifissures iad situated between setae an3 and ad3.
Setae h of mentum longer than distance between them; palps three-segmented with setal formula: 2-2-8(1); chaetotaxy of legs (without tarsi): I: 1-3-4(2)-5(1); II: 1-4-3(1)-5(1), III: 2-2-2(1)-2(1), IV: 2-1-1(1)-2(1); all legs heterotridactylous.
Distribution. Known only from the type locality.
Remark. This new species is similar to E. klabati Niedbała, 2000, but can be easily distinguished from the latter species by following characters: surface of body punctuate; two pairs of lateral carinae present; posterior six genital setae nearly equally long, g9 not obviously longer than other genital setae; all legs heterotridactylous.
