Diagnosis.
Males of
M. immaculata
are easily recognized by the reduction of the apico-prolateral fold on the TA (
Fig. 347
); this feature distinguishes them from other members of the
decorata
-group. The epigynal plate is greatly reduced, represented by a rebordered lenticular plate (
Fig. 330
).
Remarks.
Unlike other members of the
decorata
-group, the male
holotype
collected from
China
does not have a distinctive dorsal pattern on its opisthosoma, explaining why the specific epithet
immaculata
was chosen as species name by the
Zhang & Zhu (2009)
. However, the opisthosomal pattern, which is synapomorphic for the species-group, appears on all the
paratypes
collected in
Thailand
.
Description.
Male
(
paratype
,
Thailand
).
Coloration
(
Fig. 310
). Carapace uniform dark reddish brown, integument strongly granulated. Sternum orange-brown. Chelicerae brown. Coxae white; anterior legs yellowish, posterior ones pale brown. Opisthosoma dark sepia, mottled with numerous pale spots. Dorsal pattern: first pair represented by enlarged pale spots, medially connected; second pair by broad, disconnected band extending anteriorly; third pair by two smaller bands, almost fused medially; from fourth pair onwards by a series of transverse bands fusing with additional pair of pale spots. Dorsal scutum coriaceous, yellowish, elongated and narrowed, extending to half opisthosomal length.
Palp
(
Figs 347–349
). RTA digitiform, abruptly bent at half its length, gradually tapered towards blunt apex. Cymbial fold broad, reaching approximately 3/4 length of cymbium. TA terminally with bifid apical process, mesal branch sharply pointed, lateral one distinctly shorter; apico-prolateral fold indistinct; baso-prolateral fold welldeveloped, anterior margin rounded. Tegular spine truncated, apex bluntly pointed. Embolic base reniform, strongly excavated on retrolateral side; membranous area broad, triangular. Embolus filiform, elongated, originating at 180°.

Female
(
paratype

Total length 8.72; prosoma 4.14 long, 2.72 wide. Eye sizes and interdistances: AME 0.10, ALE 0.08, PME 0.08, PLE 0.07, AME–AME 0.06, AME–ALE 0.12, PME–PME 0.09, PME–PLE 0.21; MOQ: 0.28 long, 0.38 anterior width, 0.22 posterior width. Leg measurements: I 9.51 (2.57, 2.99, 2.28, 1.65), II 9.04 (2.61, 2.72, 2.28, 1.41), III 9.09 (2.63, 2.89, 2.13, 1.41), IV 9.74 (2.72, 2.81, 2.61, 1.59).
Coloration
(
Fig. 311
). Carapace orange-brown. Dorsum of opisthosoma pale brown. Dorsal pattern: first pair represented by two medially connected pale patches; second pair by broad, disconnected band extending laterally; from third pair onwards by a series of transverse bands fusing with additional pair of pale patches.
Genitalia
(
Figs 330
,
350–353
). Epigynal plate lenticular, relatively narrowed, slightly protruding over epigastric furrow, anterior median incision indistinct. Epigastric furrow rebordered. Internal genitalia with moderately long insemination ducts. Lateral margin of spermathecae greatly constricted in anterior view; apex of spermathecae blunt, strongly convoluted internal duct with 4–5 apical coils.
