Measurements of specimens from Hainan: Prodorsum: length 185–210, width 145–148, height 110–120, sensillus 90; setae: in 50, le 60, ro 95; distance between setae: in–in 95, le–le 120, ro–ro 105, in–le 35, le–ro 50; notogaster: length 270–275, width 215–220, height 155–190; setae: c1 55, c2 75, c3 90, c p 85, d1 55, d2 75, e1 85, e2 85; “ano-adanal” plate 70×35.

Surface of body smooth or prodorsum with longitudinal striations; all prodorsal and notogastral setae densely barbed, seta c2 more remote from anterior margin than setae c1 and c3; six pairs of ventral setae thick and densely barbed; one or two pairs of setae on antero-lateral position, short, thin and smooth; six pairs of smooth genital setae present; “ano-adanal” setae two, three or four pairs, covered with small barbs.

Distribution. China; Australia; Fiji; India; Indonesia; Japan; Malaysia; Papua New Guinea; Philippines; Solomon Islands; Sri Lanka; Thailand; Vietnam.

Remarks. Apoplophora pantotrema is the first record of Apoplophora in China, but it was simply listed in the paper concerning soil ecology without any description and comment ( Chu & Aoki 1997).

Niedbała (2001) concluded that some morphological features of species in Apoplophora show individual variation: the ornamentation of the body and the number of ventral and anal setae. Among the specimens we collected from a single locality, we found their body smooth or ornamented by longitudinal striations, three or four pairs of “ano-adanal” setae present, and one or two pairs of setae on antero-lateral position of ventral region. It further confirms the view of Niedbała (2001) that these features are of little use in diagnosis and taxonomy in this genus.
