( Figures 10 A-D)

Material examined — Holotype female, Petit-Saut Lake , French Guiana, date unknown, between 2007 and 2017, 4.939997°N, 53.044167°W, leg. S. Clavier ( RMNH) . Paratypes:

Three females, same data as holotype ( RMNH).

Diagnosis (Male unknown) — Cx-IV posteromedially with large projection, P4 stocky and curved.

Description — Female – Idiosoma soft, without plates or platelets, dorsally 1126 long and 925 wide, ventrally 1102 long. Coxae in three groups, Cx-I fused medially, apodemes of anterior coxae short. Cxgl-4 well distance from suture line of Cx-III and Cx-IV. Cx-IV with a large posteromedial projection ( Figure 10A). Genital field 164 long and 210 wide, with three pairs of acetabula; pregenital sclerite 78 wide. Genital plates 108 long, slightly curved ( Figure 10B). Length of P1-5: 22, 82, 54, 68, 34. P4 stocky and slightly curved ( Figure 10C). Length of I-leg-4-6: 168, 172, 144. I-leg-5 distally with two pointed setae and three fine setae, one of these bowed ( Figure 10D). Length of IV-leg-4-6: 212, 208, 190. Legs without swimming setae.

Male – Unknown.

Etymology — Named for the relatively large projections of Cx-IV.

Discussion — All but one Nearctic and Neotropical species has the palp with denticles. Only M. inermis (Cook, 1974) has the palp without denticles, but P4 of this species is more slender and the coxae form one group.
