Extended diagnosis.
Males of
M. decorata
are recognized by the relatively broad base embolus abruptly tapered at half its length, becoming thread-like (
Figs 314
,
336
). Males are similar to those of
M. filicata
sp. nov.
but in that species the embolus is entirely filiform. Females also closely resemble those of
M. filicata
sp. nov.
but can be distinguished by the well-developed lenticular epigynal plate protruding over the epigastric furrow (
Figs 321–322
), and by the apex of the spermathecae which is triangular instead of tubular in anterior view.
Redescription.
Female
(
syntype
, NHRS). See
Thorell (1895)
for measurements.
Coloration
(
Fig. 299
). Carapace uniform orange-brown. Sternum orange-brown. Chelicerae brown. Legs pale yellowish; proximal part of femora, tibiae and metatarsi slightly darker. Opisthosoma dark brown, background mottled with numerous minute spots. Dorsal pattern: first and second pairs represented by two pairs of enlarged, pale patches, second pair largest; third and fourth pairs by much smaller spots of similar size; fifth to seventh pairs by a series of transverse bands, laterally fused with additional pale patches.
Genitalia
(
Figs 321–323, 326
). Epigynal plate lenticular, protruding over epigastric furrow, with two distinctly elevated lateral lobes and shallow anterior median incision. Lateral borders retracted. Epigastric furrow strongly rebordered. Internal genitalia with long insemination ducts bent posteriorly. Spermathecae heavily sclerotized, proximal part with excavated outer margin, gradually tapered to form triangular distal apex; internal ducts strongly convoluted, with 5–6 apical coils.
Male
(NHRS, from Tagata). See
Thorell (1897)
for measurements.
Coloration
(
Figs 298
,
302–303
). Carapace uniform dark orange-brown. Sternum orange-brown. Legs yellowish; coxae pale yellowish; femora proximally yellowish brown; tibiae and metatarsi slightly darker. Opisthosoma dark brown, clothed with numerous long, erect bristles. Dorsal pattern: first and second pairs represented by two distinctly enlarged patches situated obliquely, second pair largest; third and fourth pairs by two transverse bands; fifth to eighth pairs by a series of transverse bands laterally connected to additional pale patches. Dorsal scutum coriaceous, elongated, lateral margins undulated, extending to half length of opisthosoma.
Palp
(
Figs 314–320
,
336
). RTA short and stout, strongly excavated baso-prolaterally in ventral view, gradually tapered towards bluntly pointed apex. Cymbial fold broad, slightly longer than half length of cymbium. TA terminally with bifid apical process, its mesal branch slender, sharply pointed, much longer than short lateral one; apico- and baso-prolateral fold strongly pronounced, directed mesad. Tegular spine bluntly pointed. Embolic base triangular, its anterior margin straight. Embolus broad proximally, at half its length abruptly tapered and whip shaped.
