Diagnosis.
Males are similar to those of
M. angulosa
sp. nov.
They share the following characters of the palp: the rostrated TA with a baso-retrolateral tooth and a filiform embolus (
Fig. 800
). In the present species the embolus is provided with a triangular subterminal flange (
Fig. 801
). Females can be distinguished by the rather simple internal genitalia, the ducts of which consist of simple loops (
Fig. 795
).
Etymology.
The specific epithet
brachyrhyncha
is latinized adjective of Greek βpαχDς (= short) and ρʋΎχος (= trunk), meaning short beak which refers to the shape of the TA.
Description.
Male
(
holotype
). Total length 6.29; prosoma 3.87 long, 2.47 wide. Eye sizes and interdistances: AME 0.30, ALE 0.22, PME 0.16, PLE 0.22, AME–AME 0.10, AME–ALE 0.26, PME–PME 0.18, PME–PLE 0.40; MOQ: 0.58 long, 0.46 anterior width, 0.40 posterior width. Leg measurements: I 15.82 (3.82, 4.81, 4.44, 2.78), II 13.95 (3.58, 4.10, 3.78, 2.48), III 13.26 (3.36, 3.86, 3.88, 2.14), IV 17.78 (3.91, 5.22, 5.86, 2.78).
Coloration
(
Fig. 777
). Carapace orange-brown. Chelicerae brown. Sternum orange-brown. Legs yellowish, except for coxae whitish. Dorsum of opisthosoma brown. Dorsal pattern: first and second pairs forming reniform patches situated anteriorly; third to sixth pairs represented by four pairs of pale round patches, medially with three small irregular patches running longitudinally in between.
Palp
(
Figs 800–801
). Retrolateral margin of palpal tibia strongly elevated, terminally pointed. RTA broad at base, gradually tapered towards bluntly pointed apex. TA rostrated, anterior margin horizontal; apico-prolateral process slender, sharply pointed, directed posteromesad; baso-retrolateral tooth minute. Embolic base aligned in transverse direction, anterior membranous area triangular, relatively broad. Embolus linear, broader at base, tapered towards apex, subterminally with triangular semi-transparent flange.
Female
(
paratype
).
Total length 6.01; prosoma 3.70 long, 2.50 wide. Eye sizes and interdistances: AME 0.28, ALE 0.22, PME 0.18, PLE 0.22, AME–AME 0.10, AME–ALE 0.24, PME–PME 0.18, PME–PLE 0.38; MOQ: 0.56 long, 0.44 anterior width, 0.40 posterior width. Leg measurements: I 15.38 (3.66, 4.60, 4.26, 2.60), II 13.34 (3.42, 3.90, 3.62, 2.36), III 12.68 (3.22, 3.69, 3.70, 2.04), IV 17.01 (3.74, 4.98, 5.60, 2.66).
Coloration

Fig. 778
). Carapace orange-brown. Chelicerae brown. Sternum orange-brown. Legs yellowish, except for coxae yellowish whitish. Dorsum of opisthosoma sepia, mottled with numerous minute pale spots. Dorsal pattern: first and second pairs forming reniform patches situated anteriorly; third to sixth pairs represented by four pairs of pale round patches obliquely arranged, medially with three small irregular patches running longitudinally in between.
Genitalia
(
Figs 794–795
,
802–804
). Epigynal plate tongue-shaped, without anterior incision, posterior margin protruded, extending over epigastric furrow. Spermathecae broadest medially, apically rounded.
