Marengo nitida Simon, 1900 View in CoL
Figs 1 View FIGURE 1 A, B, E, 2 A–E, 3 A–E, 4 A–C Diagnosis. The males of Marengo nitida are distinguished from that of M. crassipes and M. rattotensis by the thick, stout RTA ( Figs 2 View FIGURE 2 A, B; Benjamin, 2004: fig 65 C). Further, males and females of M. nitida can be separated from all other Marengo spp. by the round opisthosoma. Separated from M. rattotensis by the gradually sloping posterior border of the prosoma ( Figs 1 View FIGURE 1 E–F). Distinguished from M. striatipes by the flat prosoma and enlarged femur I (Benjamin, 2004: fig 67 A; Wanless, 1978: figs 5 a, b).
Description. Male. Total length: 2.8; prosoma length: 1.6, width: 1.0. Legs I: femur 0.6, patella 0.3, tibia 0.8, metatarsus 0.5, tarsus 0.2. Markings as in Fig 1 View FIGURE 1 B. The male specimens examined were darker than M crassipes , but are much lighter than males of M. rattotensis . Prosoma dark brown, sides darker, with dark patches in front just behind the AME and white patches just below the PLE ( Fig 1 View FIGURE 1 B). Opisthosoma relatively rounded, red brown, no visible markings. Legs I–IV laterally with dark markings. Eyes in three rows, first recurved, second and third straight and surrounded by dark rings ( Fig 1 View FIGURE 1 B). Chelicera, labium and dorsal parts lighter in colour. Leg formula 1432. Tibia I with 2 / 2 /0/ 2 spines, metatarsus I with 2 / 1 spines. Palp: tibia short, RTA short, stout ( Figs 2 View FIGURE 2 A, B, 3 B, D, C). Cymbium oval, tip excavated ( Fig 3 View FIGURE 3 D), bulb bilobed, embolus short, coils 1.5 times ( Figs 2 View FIGURE 2 A, B, 3 A–C).
Female. Total length: 3.0; prosoma length: 1.5, width: 0.6. Legs I: femur 0.5, patella 0.2, tibia 0.5, metatarsus 0.3, tarsus 0.2. Markings as in Fig 1 View FIGURE 1 A. Prosoma dark brown, sides darker, with dark patches in front just behind the AME and white patches just below the PLE ( Fig 1 View FIGURE 1 A). Opisthosoma round, light brown, dorsally with very characteristic markings. Legs I–IV laterally with dark markings. Eyes in three rows, first recurved, second and third straight and surrounded by dark rings ( Fig 1 View FIGURE 1 A). Chelicera, labium and dorsal parts lighter in colour. Leg formula 1432. Tibia I with 2 / 2 /0/ 2 spines, metatarsus I with 2 / 1 spines. Epigynum and vulva as in Figs 2 View FIGURE 2 C–E.
Remarks. Simon (1900) gives the type locality as Kandy but the museum labels give the type locality as Galle (original labels give no details of the exact locality). Simon (1901: fig 574 a) illustrates a specimen that has a rounded opisthosoma similar to the material from Galle and material examined for this study. I have no doubt that the current specimens examined by me are conspecific with type material.
Distribution. Known only from lowland rainforest in Sri Lanka.
