Etymology. The specific epithet is a noun in apposition taken from type locality.

Diagnosis. Males of M. pipa   sp. nov. are most similar to those of M. nigritarsis   , both of which have a thick embolic disc with a straight prolateral edge and curved retrolateral edge ( Figs 25C View FIGURE 25 , 27A View FIGURE 27 , 36C View FIGURE 36 , 37A View FIGURE 37 , 57C, E View FIGURE 57 ). However, they differ by having a shorter process on the embolic disc and a shorter embolus ( Figs 57C, E View FIGURE 57 ). Also, the base of the embolus shaft is larger in M. pipa   sp. nov. ( Figs 27E View FIGURE 27 , 28A View FIGURE 28 , 37G View FIGURE 37 , 40C View FIGURE 40 ). The general pattern of the epigynal structures among M. pipa   sp. nov. and M. nigritarsis   are similar, with both having copulatory ducts that encircle the primary spermathecae ( Figs 26 View FIGURE 26 C–D, 27G, 58E, G). However, females of M. pipa   sp. nov. can be distinguished by having the primary spermathecae with different widths (being dilated at their basal portion and thinner at their distal end; Figs 26 View FIGURE 26 C–D, 27G, 58E), whereas in M. nigritarsis   the primary spermathecae is evenly wide throughout their length ( Figs 35 View FIGURE 35 H–I, 37I, 58G).

Description. Male (Holotype, MPEG 34352). Total length: 3.14. Carapace 2.05 long, 1.47 wide, 0.98 high. Ocular quadrangle 0.92 long. Anterior eye row 1.25 wide, posterior 1.02 wide. Legs 1432. Length of legs: I 4.52 (1.38 + 1.76 + 1.38); II 3.52 (1.11 + 1.27 + 1.14); III 4.10 (1.36 + 1.43 + 1.31); IV 4.14 (1.24 + 1.36 + 1.54).

Tibia I p0-1-0, r0, v2-2-2; II p0-1-0 (or p1-1-0), r0-1-0, v1r-2-2 (or v1r-1r-2); III–IV p0-1-1-0, r1-1-1-0, v1p-0-0-2. Metatarsus I p1-1, r0, v2-2; II p1-1, r1di, v2-2; III d1p-0-0, p1-0-2, r1-0-2, v2-0-2 (or v1p-0-2); IV p-1-1-2, r1-1-2, v1p-0-2.

Color in alcohol ( Figs 25 View FIGURE 25 A–B): carapace with triangle of scales pointing backwards; areas around triangle with dense concentration of scales; abdomen ventrally with three longitudinal dark stripes, almost fused, and pale edge; legs: femur I with prolateral surface with dark stripe and distal region with a dark retrolateral spot, II distal region with prolateral and retrolateral dark spot, III with dark distal ring and proximal region with dark prolateral spot, IV with dark distal ring; tibia I–II with dark proximal ring, III–IV with proximal and distal dark ring; tarsus I almost black, II without dark marks; III–IV with dark proximal spot.

Palp: RTA finger-shaped ( Figs 25D View FIGURE 25 , 27B View FIGURE 27 ); embolic disc thick, with straight prolateral edge and curved retrolateral edge ( Figs 25C View FIGURE 25 , 27A View FIGURE 27 ); PED slighty longer than exposed portion of embolic disc, emerging from prodistal part of embolic disc ( Figs 27A, E View FIGURE 27 ); tip of embolus ending beyond tip of PED ( Figs 27A, E View FIGURE 27 ).

Female (Paratype, MPEG 34349). Total length: 3.68. Carapace 2.09 long, 1.63 wide, 1.10 high. Ocular quadrangle 1.11 long. Anterior eye row 1.38 wide, posterior 1.22 wide. Legs 4312. Length of legs: I 3.44 (1.09 + 1.33 + 1.02); II 3.37 (1.10 + 1.22 + 1.05); III 4.38 (1.42 + 1.52 + 1.44); IV 4.45 (1.26 + 1.51 + 1.68).

Leg macrosetae: Femur I d1-1-1, p1di, r0; II–IV d1-1-1, p1di, r1di. Patella I–II 0; III–IV p0, r1. Tibia I p0-1-0, r0, v1r-1-2; II p0-1-0, r0-1-0, v1r-2-2; III p0-1-1-0, r1-1-1-0, v1p-0-0-2; IV p0-0-1-0 (or p0-1-1-0), r1-1-1-0, v2di (or v1p-0-0-2). Metatarsus I–II p1-1, r1di, v2-2; III d1p-0-0, p1-0-2, r1-0-2, v2-0-2 (or v1p-0-2); IV d1p-0-0, p1-0-2 (or p1-1-2), r1-0-2 (or r1-1-2), v0-1p-2.

Color in alcohol ( Figs 26 View FIGURE 26 A–B): carapace as in male; legs: femur I prolateral surface with dark stripe and distal region with dark retrodorsal spot, II distal region with dark dorsal spot and proximal region with dark prolateral spot, III distal region with dark dorsal spot and proximal region with dark proventral spot, IV with dark distal ring and proximal region with prolateral and retrolateral dark spot; tibia I–II with dark proximal ring and distal region with prolateral and retrolateral dark spot, III–IV with proximal and distal dark ring; tarsus I–II without dark marks, III–IV with dark proximal ring.

Epigyne ( Figs 26 View FIGURE 26 C–D, 27F–G, 28E–F): copulatory openings very close to each other and placed more anteriorly than primary spermathecae; copulatory ducts longer and encircling primary spermathecae; proximal copulatory ducts approximately with same length as distal section; primary spermathecae with dilated initial portion, tapering towards the fertilization ducts; primary spermathecae anteriorly projected.
