Diagnosis.
Males of
M. platycera
sp. nov.
are easily recognized by the second RTA (
Figs 176–178, 179
) which is relatively broad at base, in combination with the embolus carrying a subterminal process and a triangular apical flange (
Fig. 181
). Females are distinguished from those of
M. cryptocera
sp. nov.
by a deeper anterior median incision on the epigynal plate and by the narrower apex of their spermathecae in anterior view.
Etymology.
The specific epithet is a latinized combination of the Greek words (πλατʋς = broad, flat; κƐρας = horn, antler) meaning ‘wide horn’, and refers to the broadest second RTA found among males of this species-group. Noun in apposition.
Description.
Male
(
holotype
). Total length 5.69; prosoma 2.80 long, 2.29 wide; opisthosoma 2.89 long, 2.12 wide. Eye sizes and interdistances: AME 0.13, ALE 0.14, PME 0.15, PLE 0.14, AME–AME 0.14, AME–ALE 0.24, PME–PME 0.18, PME–PLE 0.32; MOQ: 0.50 long, 0.36 anterior width, 0.46 posterior width. Leg measurements: I 7.73 (2.12, 2.38, 1.70, 1.53), II 7.56 (1.95, 2.38, 1.87, 1.36), III 7.48 (2.04, 2.29, 1.95, 1.19), IV 9.11 (2.12, 2.97, 2.80, 1.20).
Coloration
(
Fig. 158
). Carapace uniform orange-brown. Sternum reddish brown. Chelicerae brown. Coxae pale yellowish, other leg segments yellowish brown. Dorsum of opisthosoma sepia, mottled with numerous minute pale spots. Dorsal pattern: first and second pairs fused, forming reniform patches; third and fourth pairs represented by two pairs of oblong patches; from fifth pair onwards by a series of transverse median bands. Dorsal scutum orange-brown, edge sharply defined.
Palp
(
Figs 176–181
). RTA digitiform, elongated, lateral margins parallel in retrolateral view, apex blunt. Second RTA more or less quadrangular, broad at base, abruptly tapered to rounded apex. Meso-retrolateral side of tibial moderately elevated. TA rostrated, strongly concave prolaterally; with straight apical ridge; apico-prolateral fold sharply pointed, directed mesad; apico-prolateral process absent; baso-retrolateral flange triangular, apex blunt, directed mesad, clearly visible in prolateral view. Conductor terminally sharp and pointed. Embolus flattened, originating at 270°, with broad, semi-transparent flange and lanceolate apex.
