Material.1 female- Jotus abnormis Bos.et Str., - Japan, Aichi Pref.[widely distributed in Japan and common], 19.VII.1954, leg.det.T.Yaginuma ; 1 male - Jotus abnormis - Japan, Kaibara, Hyogo Pref., 10.VIII.1962, leg.I.Yoshimi, det.T.Yaginuma; 1 male - Jotus abnormis - Japan, Kumamoto Pref., 6.VI.1958, leg.T.Irie, det.T.Yaginuma ; all - coll.J.Prosznski.

Comparative material. 1 female - typus - Icius abnormis Bos.+Strand - Japan: Saga, W.Donitz 1882 - coll.SMF 2516.
 
 Male light coloured, long legged with thin continuous dark line along anterior surface of femora I.
 Cephalothorax pale with whitish yellow eye field and pale median thoracal streak.
 Anterior and lateral margins of eye field black, sides of thorax pale fawnish, whitish elongate spot above the posteriorly lateral margin of thorax.
 Abdomen elongate, whitish with grey dotted streaks along the margins.
 Arontal aspect. Coloration pale yellowish, chelicerae elongate.
 Eyes I surrounded black but in frontal view that black colour is invisible, instead direct white short setae surrounding with single layer eyes I become striking.
 Ventral surface generally pale yellowish, sternum thinly grey margined.
 Abdomen whitish with three dark greyish streaks median and two diagonal running from epigastric fold to the posterior spiracle where they fuse.
 Immediately behind spiracle there is a white spot passing laterally into blackish ring around the spinnerets.
 The membrane near spinnerets is whitish, spinnerets ventrally pale greyish, dorsally whitish.
 Legs long, dorsally light, lateral surfaces fawnish with single thin dark lines along femora I and some other joints.
 Pedipalps rather long, the shape of palpal organ shown on figs.177-179.
 
 Female. One of two studied adult specimens is twice smaller and almost whitish, with faint traces of abdominal dorsal pattern.
 Apart from the similarities in internal structure of epigyne there are no indications of their conspecific relationships.
 Description based on bigger specimen.
 Dorsal coloration generally resembles that of the male.
 Cephalothorax more fawnish.
 Marginal greyish streaks on abdomen fainter and following them light stripes on lateral surfaces more prominent.
 Legs shorter, yellowish, without darker lines on femora.
 Frontal aspect generally whitish and yellowish.
 Ventral surface. Like in the male, three dark stripes on abdomen in a form of lines of spots, they fuse in front of posterior spiracle.
 Dark ring before spinnerets broken by paler spot behind spiracle as in male.
 Epigyne small and without clear distinctive features (figs.172-176), its copulatory canals particularly short.

 length of cephalothorax 2.44, length of abdomen 3.78,
 length of eye field 1.06, width of eye field I 1.46,

 I  0.50+0.90+1.04+0.70+1.40;
II  0.50+0.87+0.95+0.70+1.34;
