Species diagnosis

(based on adult female). Body nearly round, broadest across thorax and anterior abdomen. Body strongly lifted by ventral ovisac. Anal plates posteriorly elongate; each plate with posterior margin about two times as long as anterior margin, with 3 fine apical setae and a well-developed discal seta. Three types of ventral tubular ducts present; smallest type forming complete broad submarginal band.

Description

Living appearance. Body nearly round, broadest across thorax and anterior abdomen. Prior to oviposition, dorsum reddish light brown posteriorly and dark brown anteriorly (Fig. 1), changing to reddish brown with a dark brown marginal ring at full-maturity. Mature adult females produce an ovisac mainly from beneath abdomen. No wax present on dorsum at oviposition. Post-oviposition females sclerotised and not shrivelled. Ovisac white, very convex, nearly hemispherical. Body strongly lifted posteriorly by ovisac.
Slide-mounted material (measured individuals: n = 10).Body elongate-oval, 2.9–4.0 mm long, 2.9–4.0 mm wide, margin with a shallow indentation at each stigmatic cleft; anal cleft 1/5–1/6 body length.
Dorsum. Derm membranous when young. Dermal areolations well developed. Dorsal setae spiniform, 7–12 mm long, frequent, scattered over entire dorsum, each with a well-developed basal socket. Preopercular pores each ring-like, conspicuous, 3.5–7.0 mm wide, consisting of a compact group of 2–11 pores anterior to anal plates. Dorsal tubular ducts absent. Dorsal microductules frequent throughout. Dorsal tubercles absent. Anal plates posteriorly elongated; each plate with posterior margin about two times as long as anterior margin, each with 3 fine apical setae and a discal seta; length of plates 214–249 mm; width of single plate 85–122 mm; each plate with well-developed supporting bars. Ano-genital fold with 2 pairs of setae along anterior margin and 1 or 2 pairs laterally. Anal ring with 6–8 setae (mostly 8). Eyespot present near margin
Margin.Marginal setae spinose, each with a simple pointed apex and a well-developed basal socket; length highly variable, each seta 20–107 mm long, with 10–13 setae present on each side between stigmatic clefts. Stigmatic clefts shallow, each with 0–3 (mostly 3) stigmatic spines in each cleft, longest spine 92–134 µm long, about 3–4 times as long as lateral spines.
Venter.Derm membranous. Pregenital disc-pores each with 8–11 loculi (mainly 10), present around genital opening and on mediolateral areas of all abdominal segments and metathorax; a small group also present laterad of each coxa. Spiracular disc-pores each with 5 loculi, present between margin and each spiracle in band 1–5 pores wide; anterior bands with 30–63 pores and posterior bands with 45–80 pores. Ventral microducts evenly distributed throughout venter. Three types of ventral tubular ducts present: type I with well-developed terminal gland and a stout inner ductule, present medially on head and thorax; type II rather narrower with a long, much thinner inner ductule, shallow cup-shaped invagination, and a well-developed terminal gland, sparse medially on posterior abdominal segments and also in a submarginal band with ducts of type III; type III ducts similar to type II, but with a short, filamentous inner ductule and very small terminal gland, mainly present in a broad submarginal band. Ventral setae: 3 pairs of long pregenital setae and 3–6 pairs of long setae between antennae; other setae short and fine. Spiracles as usual for family; width of each peritreme: anterior 47–60 mm, posterior 58–70 mm. Legs well developed; each with tibio-tarsal articulation and articulatory sclerosis; all claws without denticle; both claw digitules rather broad and slightly shorter than thin tarsal digitules; trochanter + femur 240–306 mm, tibia 162–198 mm, and tarsus 92–118 mm. Antennae each with 7 or 8 segments (mostly 8); total length 342–412 mm. Labium approximately 47–118 mm wide.

Distribution

Thisspecies occurs widely across central and northern parts of Japan from Honsyû [Honsyu], Kyusyû [Kyushu] and Sikoku [Shikoku] districts.

Notes

A good photograph of ovisac-producing adult females is presented in Kawai (1980)[5]. Kuwana’s type material of this species could not be found in the Kuwana collection of the National Institute of Agricultural Environmental Sciences, Tukuba [Tsukuba] and is presumed lost.
