Melychiopharis cynips Simon 1895: 905   , figs. 972–973 (Female holotype from the Amazon Basin, in the Muséum National d’Histoire Naturelle, Paris, not found, probably lost). Roewer 1942: 911; Bonnet 1957: 2765; Levi 2002: 562; Platnick, 2005 (in Theridiidae   ).

Diagnosis. See generic diagnosis above.

Description. Male. Carapace longer than wide, widest at the middle. Carapace, sternum and legs red­brown. Dorsum of opisthosoma yellow, with a large central and four marginal black patches. Venter orange. Eyes subequal in size ( Fig. 1 View FIGURES 1–3 ). Anterior median eyes separated by 1.5 diameters, 1.0 diameter from posterior medians. Lateral eyes approximately 3.0 diameters from the anterior medians. Median ocular quadrangle almost square. Height of clypeus equal to 1.5 diameters of anterior median eyes. Leg articles thin. Opisthosoma almost as long as wide. Dorsum covered with a single, dish­shaped scutum, with a lateral flange ( Fig. 1 View FIGURES 1–3 ). Venter soft, with an anterior and a posterior sclerotized area posterior to the epigastric groove. Anterior sclerotized area with a marked posterior sulcus ( Fig. 4 View FIGURES 4–10 ). Colulus small, without setae. Total length 1.9. Carapace 0.9 long, 0.6 wide. Femur I 0.64, patella and tibia 0.66, metatarsus 0.46, tarsus 0.25. Patella and tibia II 0.61, III 0.49, IV 0.65. Opisthosoma 0.9 long, 0.6 wide. Tegulum elongated mesally, with a rounded, sclerotized hump. Median apophysis distally bent. Paracymbium curved, convex, and rectangular in dorsal view ( Figs. 6–8 View FIGURES 4–10 ).

Female. Body shape and coloration as in male, except for prosoma orange and opisthosoma yellow with five black patches. Relative eye interdistances as in male. Height of clypeus 2.5 diameters of anterior median eyes. Total length 2.5, carapace 1.1 long, 0.6 wide. Femur I 0.8, patella and tibia 0.8, metatarsus 0.5, tarsus 0.3. Patella and tibia II 0.7, III 0.6, IV 0.7. Opisthosoma 1.4 long, 1.3 wide. Epigynum median depression extending posteriorly, beyond epigastric sulcus. Copulatory openings located on the anterior corners of the median depression, not visible in ventral view. Copulatory ducts long, twisted, and encapsulated. Spermathecae oval and close together. Fertilization ducts long, dorsal to the spermathecae ( Fig. 10 View FIGURES 4–10 ).

Natural history. One male specimen was collected by beating on the understory vegetation inside a 1 ha dry land forest fragment in Central Amazonia (IBSP 48718). The specimens from Reserva Florestal Adolpho Ducke were collected by fogging on the canopy of three tree species: Pouteria glomerata   ( Sapotaceae   ), Micropholis guyanensis   ( Sapotaceae   ), and Corythophora alta   ( Lecythidaceae   ). Unfortunately no additional natural history observations were obtained for any specimen, and it is not known whether or not this species builds webs.

Distribution. Northern, northeastern and central Brazil ( Fig. 11 View FIGURE 11 ).
