Type material: Holotype: male from Maromba   , Parque Nacional de Itatiaia [22 ° 19 ' S; 44 ° 32 ' W], Visconde de Mauá, Minas Gerais, Brazil, 18 December 1991, R.L.C. Baptista, deposited in IBSP 7737.

Etymology. The specific name is a noun in apposition that refers to the type locality of the holotype.

Diagnosis. Males of Scytodes maromba   n.sp. resemble those of S. tacapepucu Rheims & Brescovit   by the distal region of the male palp with a prolateral distal hyaline keel and a very long retrolateral sclerotized process ( Figs. 53–55 View FIGURES 52 – 61. 52 – 55 ; Rheims & Brescovit 2006: 306, figs. 42–43). They are distinguished by the distal area of bulb longer than the sclerotized process ( Fig. 54 View FIGURES 52 – 61. 52 – 55 ), by the smaller prolateral distal keel and by the presence of an additional prolateral subdistal keel ( Figs. 53, 55 View FIGURES 52 – 61. 52 – 55 ).

Pedipalps orange. Palpal femora and patellae with prolateral brown mark. Palpal tibiae with a dorsal and a prolateral brown stripe. Labium pale yellow with black marks at base. Endites pale yellow. Sternum cream coloured with brown markings in front of each coxae. Legs orange, except patellae brown. Femora I –IV with pair of longitudinal black stripes. Tibiae I –IV with brown ends and dorsal longitudinal brown stripe. Abdomen whitish gray with very faint black pattern ( Fig. 52 View FIGURES 52 – 61. 52 – 55 ). Total length 3.9. Carapace slightly domed, 1.9 long, 1.5 wide. Eye diameters: PME 0.10, ALE 0.10, PLE 0.10. Lateral eyes on a tubercle. Chelicerae with subapical hyaline keel and inconspicuous stridulatory ridges. Labium 0.12 long, 0.26 wide. Sternum 1.04 long, 0.80 wide. Leg measurements: I: femur 4.9, patella 0.5, tibia 5.3, metatarsus 6.9, tarsus 0.8, total 18.4; II: 3.4, 0.5, 3.4, 4.1, 0.6, 12.0; III: 2.2, 0.5, 1.9, 2.3, 0.5, 7.4; IV: 3.2, 0.5, 2.9, 3.2, 0.6, 10.4. Palpal femur with stridulatory pick short and slender with rounded and slightly projected socket. Cymbium with pair of strong distal spines ( Fig. 53 View FIGURES 52 – 61. 52 – 55 ). Bulb 0.78 long, slightly bent medially. Distal region with pair of prolateral hyaline keels ( Figs. 53, 55 View FIGURES 52 – 61. 52 – 55 ) and retrolateral long, slightly curved, sclerotized process ( Fig. 54 View FIGURES 52 – 61. 52 – 55 ).
