 Proposing the above synonymies and nomenclatorical changes I am not fully convinced my interpretations are right ones.
 I suggest further check of types from NH Museum in Vienna and new, fresh material from Japan (J.P.).
 
 Male. Cephalothorax long and flat, brown with intensely white brown margin and intense white line beneath eyes I.
 There is also a  beard of longer but sparse white setae under eyes I median, overhanging bases of dark brown chelicerae and growing on them.
 Abdomen greyish fawn with paler spots, making an indistinct pattern of darker median streak along anterior half of abdomen, and a few short and indistinct chevrons medially in the posterior three fourth.
 A pair of white spots in two third brown of abdomen.
 Sides of abdomen white.
 Pedipalps generally fawn with distal end of femur whitish.
 Characterized in dorsal and lateral view on specimen, by large round bulbus and long cymbium.
 The details of structure are shown on figs.145-149.
 The drawings of palpal organ of "Menemerus brachygnathus" and "Menemerus confusus" are incomparable but correspond with features of the palpal organ of the single specimen described here.
 
 Female. Cephalothorax flat and long, dark brown, with intense white setae on the margin, white spot beneath eyes I lateral and dorsally between eyes I median.
 Abdomen broad, flattened, marginally whitish, with intense brownish rusty rim around dorsal surface making frame to a pattern of faint brownish spots (anterior half median line crossed, four chevrons centrally and posteriorly) on whitish background.
 Legs brown with some parts lighter fawn.
 Whole area beneath eyes I covered with short white setae except shallow fawnish arches on rim above chelicerae, just beneath eyes lateral.
 Chelicerae blackish brown, pedipalps fawnish with long but sparse white setae, anterior legs brown.
 Ventrally cephalothorax and appendages generally fawnish to brownish, abdomen yellowish grey.
 Epigyne was covered with waxy secretion which fell out during maceration (figs.153-159).
 It is an oval shallowly depressed plate, with a low ridge medially, copulatory openings located posteriorly, lead to thick walled sclerotized chamber, from which short canals with prominent accesory gland opening lead to small spermathecae.
 These internal organs in proportions to the whole epigyne are very small (figs.154-155,158-159)
.
 The internal structures seem to be identical with those in syntype specimen of Menemerus brachygnathus (Thorell) from Burma, both specimens differing slightly in general outline of epigyne and distance between copulatory openings in relation to the rim of epigyne.
 This resemblance confirms conspecific status of both forms.
 The female identified as Menemerus brachygnathus from Japan differs from that identified as Menemerus confusus in minor details of colour pattern, particulary of abdomen, which could be considered individual variation.
 It displays colour pattern characters which seem to be diagnostic, particulary white setae spots on the clypeus.
 Epigyne agrees with the above described.
