Diagnosis. This species is similar to M. dinguh Song & Kim, 1997 , but can be separated from the latter by: 1) atrium distinct in the new species versus indistinct in M. dinguh ; 2) median plate narrow band-shaped in the new species versus wide plate-shaped in M. dinguh ; 3) ALE smallest in the new species versus as large as PME and PLE in M. dinguh ; 4) the patterns on abdominal dorsum.

Etymology: The specific name comes from the combination of latin prefix “ bi- ” and latin word “ umbonalia ”, meaning “two” and “apophysis” respectively, and referring to the epigyne with two lateral obtuse lobes, adjective in apposition.

Description. Female (holotype): total length 7.50; Prosoma 3.65 long, 2.50 wide; opisthosoma 3.85 long, 2.75 wide. Carapace blackish brown, prosoma slightly swollen. AER and PER slightly procurved; AME the largest (0.20); ALE (0.15); PME=PLE (0.17); AME = ALE (0.12), AME-ALE (0.18) <PME-PLE (0.31); MOA long 0.76, front width 0.52, back width 0.45; clypeus height 1.05. Sternum cordiform, yellow, haired around, longer than wide, margin with small pointer extensions fitting in coxal concavities of legs. Chelicerae reddish with scopulae on both margins of fang furrow, chelicerae without teeth, fang very short. Gnathocoxae white anteriorly and yellow posteriorly, with scopulae at tips. Labium yellowish brown, wider than long, and wider medially. Legs orange with many spines except femora brown. Leg measurements: I 8.25 (2.40, 2.50, 2.05, 1.30), II 7.40 (2.35, 2.50, 1.50, 1.05), III 8.30 (2.40, 2.65, 1.95, 1.30), IV 8.85 (2.50, 2.55, 2.40, 1.45); formula 4, 1, 3, 2. Opisthosoma dorsum grayish dark, anteriorly with 3 pairs of yellow spots, posteriorly with 3 white transverse bars.
