Diagnosis.
Males of
M. cryptocera
sp. nov.
can be recognized by the filiform embolus (
Fig. 186
) and the presence of a mesal tooth on the TA (
Figs 186–188
). This new species is similar to
M. callicera
sp. nov.
in possessing a peculiar triangular elevation on the retrolateral side of the male palpal tibia. Females can be distinguished from those of
M. platycera
sp. nov.
by the shorter spermathecae, their unmodified apex are distinctly wider.

Etymology.
The specific epithet is a latinized combination of the Greek words (κρʋπτος = hidden, secret; κƐρας = horn, antler), and refers to the second RTA which is found only in this species-group. Noun in apposition.
Description.
Male
(
holotype
). Total length 6.23; prosoma 3.06 long, 2.51 wide; opisthosoma 3.16 long, 2.32 wide. Eye sizes and interdistances: AME 0.12, ALE 0.14, PME 0.15, PLE 0.14, AME–AME 0.14, AME–ALE 0.23, PME–PME 0.18, PME–PLE 0.33; MOQ: 0.52 long, 0.38 anterior width, 0.48 posterior width. Leg measurements: I 8.46 (2.32, 2.60, 1.86, 1.67), II 8.27 (2.13, 2.60, 1.04, 1.48), III 8.18 (2.23, 2.51, 2.13, 1.30), IV 9.96 (2.32, 3.25, 3.06, 1.32).
Coloration
(
Fig. 156
). Carapace uniform orange-brown. Sternum brown. Chelicerae dark brown. Legs yellowish; coxae whitish; femora and tibiae dark brown proximally. Dorsum of opisthosoma dark sepia. Dorsal pattern: first and second pairs fused, forming reniform patches; third and fourth pairs represented by paired oblong bands; fifth pair by transverse chevron. Dorsal scutum orange-brown, edge sharply defined.
Palp
(
Figs 166–167
,
186–188
). RTA digitiform, lateral margins parallel, apex terminally bluntly pointed. Second RTA triangular, slightly curved ventrally, shorter than RTA. Meso-retrolateral side of tibia strongly elevated, perpendicular to RTA in ventral view. TA with short, sharply pointed apico-prolateral fold; apico-prolateral process absent; mesal tooth triangular, situated prolaterally; basal ridge slightly elevated. Embolic base oval; membranous area indistinct. Embolus filiform, originating at 270°.
