Etymology. The species is named after Mr. Song Li; noun (name) in genitive case.
Diagnosis. Males of the new species can be distinguished from all other
sobria
-group species except
M. sobria
(Thorell, 1890)
(see
Dankittipakul
et al.
, 2012
) and
M. clavigera
Dankittipakul, Jocqué & Singtripop, 2012
by the absence of a baso-prolateral tooth on the tegular apophysis. The new species can be distinguished from
M. sobria
and
M. clavigera
by the sperm duct at the middle of the embolic base (
vs.
at the edge in
M. sobria
) and lacking a subapical tooth on the tegular apophysis (
vs.
present in
M. clavigera
). The female is similar to
M. caperata
Dankittipakul, Jocqué & Singtripop, 2012
by having spermathecae with eight coils. However, the female of the new species can be distinguished by the unexpanded middle part of the spermathecae (
vs.
expanded in
M. caperata
).

Description. Male (
holotype
). Total length 5.28; carapace 2.67 long, 1.90 wide, opisthosoma 2.61 long, 1.71 wide. Eye sizes and interdistances: AME 0.08, ALE 0.11, PME 0.14, PLE 0.10, AME–AME 0.07, AME–ALE 0.15, PME–PME 0.08, PME–PLE 0.27, AME–PME 0.18, ALE–PLE 0.04. Leg measurements: I 6.08 (1.59, 1.95, 1.35, 1.19), II 5.40 (1.44, 1.67, 1.23, 1.06), III 5.63 (1.45, 1.66, 1.45, 1.07), IV 7.67 (1.95, 2.17, 2.13, 1.42).
Coloration (
Fig. 84E
). Carapace brown. Sternum yellowish brown. Chelicerae brown. Coxae whitish, other leg segments yellowish. Opisthosoma dark brown. Dorsal pattern: first pair of spots reniform; second to fourth pairs with paired round spots, followed by three spots, posterior one largest.
Palp (
Figs 76
,
82A
). Patella almost as long as wide. Tibia with two apophyses. Ventral tibial apophysis and retrolateral tibial apophysis digitiform, ventral ramus of retrolateral tibial apophysis larger than dorsal, longer and digitiform, dorsal ramus shorter and dentiform. Cymbium with broad cymbial fold. Tegular apophysis rostrated; anterior-prolateral flange blunt at tip, directed prolaterally; anterior-prolateral tooth triangular, with broad base; basal tooth absents. Sperm duct at middle of embolic base. Embolus with large base, at ca. clock 5:30 position, embolus whiplike.
