description: Apoplophora dentata sp. nov.
(Figs. 1–4)
Material examined: Holotype: Adult (in alcohol), CHINA: Tibet, Mêdog County (29°19'31.08"N, 95°19'59.51"E), from litter, 800M, 9, Jan., 1983, leg. Yin-Heng Han. Paratype: 1 adult (in alcohol), with same data as holotype.
Etymology. The new specific name “ dentata ” is from Latin, and refers to the dentate margin of the rostrum.
Diagnosis: Anterior margin of prodorsum finely dentate; all prodorsal and notogastral setae faintly barbed, except setae c3 fine, short and smooth; six pairs of ventral setae and setae h2 and h3 faintly barbed, nearly uniformly thick, but h2 and h3 much longer.
Measurements of adult holotype: Prodorsum: length 285, width 240, height 160, sensillus 145, setae: in 100, le 110, ro 110, distance between setae: in–in 100, le–le 190, ro–ro 165, in–le 60, le–ro 65; notogaster: length 400, width 365, height 290; setae: c1 95, c2 100, c3 60, c p 100, d1 100, d2 100, e1 105, e2 110; distance between setae: c1– d1 120, d1–e1 255; ventral region: ventral setae: v1 55, v2 60, v3 60, v4 75, v5 75, v6 60, h2 90, h3 90, an1 40, an2 45, an3 40; “ano-adanal” plate 95×55.
Large species. Colour yellow. Surface of body smooth.
Anterior margin of rostrum finely dentate; sensillus long, thin, setiform, sparsely covered with faint barbs unilaterally; prodorsal setae in, le, ro faintly barbed; exobothridial seta thin, long, several times longer than diameter of bothridium, sparsely covered with small barbs; comparative length: ro = le> in> ex; lamellar seta situated between interlamellar and rostral setae, slightly closer to interlamellar seta.
Notogaster with eight pairs of setae, faintly barbed, relatively thick except setae c3 thin, short and smooth; seta c2 more remote from anterior margin than setae c1 and c3.
Ventral region with six pairs of ventral setae, nearly uniformly thick, faintly barbed as notogastral setae; setae h2 and h3 faintly barbed, equally thick with ventral setae, but much longer; genital plates with six pairs of smooth setae; “ano-adanal” plates with three pairs of faintly barbed setae.
Distribution. Known only from type locality.
Remarks. This new species is similar to A. heterotricha Mahunka, 1987, A. malaya Mahunka, 1991 and A. solomonensis Niedbała, 1998 in having short, fine and smooth seta c3. It differs from them by the following combined characters: prodorsal, notogastral and ventral setae faintly barbed, except setae c3 and genital setae; all ventral setae nearly uniformly thick; setae h2 and h3 longer than ventral setae; anterior margin of rostrum finely dentate. This new species is also similar to A. phalerata Niedbała, 2000 in having two barbed long setae on antero-lateral position of ventral region, but differs from the latter by: seta c3 fine, smooth and shorter than other notogastral setae; all prodorsal setae nearly equally thick, except setae ex; rostrum finely dentate anteriorly; all setae, except genital setae and setae c3, faintly barbed.
