Asadipus muticus Simon, 1897b: 15 (female holotype from ‘‘Nova Hollandia orient.’’ in MNHN, examined).

Stratius muticus: Simon, 1898: 217 .

DIAGNOSIS: Males can easily be recognized by the broadened retrolateral tibial apophysis and enlarged median apophysis (figs. 430, 431), females by the posteriorly expanded epigynal midpiece (fig. 432).

Abdominal dorsum dark gray, almost completely covered by orange scutum, without pair of transverse white stripes, soft portions of cuticle with interrupted narrow lines of white spots, venter pale white, with four longitudinal rows of tiny orange sclerotizations; legs unmarked. Leg spination: tibiae: III r0­1­1; IV p0­1­1, v1p­2­2; metatarsi: III v0­2­ 1p. Retrolateral tibial apophysis greatly widened basally (fig. 431); embolar base shifted retrolaterally, embolar apophysis long, spikelike, tegular apophysis long, flat, median apophysis greatly enlarged, elongated (fig. 430).

FEMALE: Total length 9.3. Coloration as in male. Leg spination as in male except metatarsus III v2­2­ 1p. Epigynal midpiece posteriorly widened, with steeply sloping sides (fig. 432); dorsalmost ducts directed longitudinally (fig. 433).
