Menoscelis saginata Mulsant, 1850 , by subsequent designation of Crotch (1874) . Diagnosis . Menoscelis is a Neotropical genus that is structurally similar to Diazonema Weise, 1926 , but differs from all other genera of the tribe in the highly modified protibia, angulate near its base ( Figs 5 D–E) and the transverse female genital plate with spoon–like setae near the apex. Diazonema presents a combination of short and compressed protibia, and a transverse female genital plate lacking spoon–like setae near the apex. In addition to the generic characters described by Gordon & Canepari (2008) , species of this genus have other useful characters that aid in their recognition: body usually large ( 4.5–7.5 mm ) and rounded, moderately to strongly convex. Dorsal surface glabrous or pubescent, maculate or not. Prosternum process about half the coxal diamenter, surface with complete or incomplete carinae joined anteriorly, forming a triangle ( Figs 5 C, 6E). Prosternal carinae often joined, sometimes connected to the anterior margin of the prosternum by a single carina ( Figs 8 A–G, 9A–E). Epipleura large, external margin explanate ( Figs 5 H, 6H). Protibia flattened, medially emarginate or with parallel sides, tibial groove deep, long, not flanged posteriorly, angulate near base ( Figs 5 D–E, 6F–G); meso- and metatibia narrow, medially emarginate or with parallel sides, not flanged, with shallow tibial groove ( Figs 5 F, 6I ). Abdominal postcoxal line incomplete, recurved or slightly recurved ( Figs 5 G, 6J). Parameres symmetrical; basal lobe asymmetrical. Sipho slender with well-developed, T-shaped siphonal capsule ( Figs 1 E–G, 4D–F). Coxites transverse with spoon-like setae near apex, styles well developed, with or without apical setae; infundibulum lacking; sperm duct simple, uniform in diameter ( Figs1 H, 2E, 3F). Spermatheca with rounded cornu and narrow at base; distal capsule adjacent to cornu or sperm duct ( Figs 2 F, 3G). Remarks. Two species, M. angeloi sp. nov. and M. cordata sp. nov. , lack the protibial emargination but are considered members of Menoscelis due to the described characters and male and female genital patterns.
