Diagnosis and comments. Species of Neoidiotypa are easily distinguished from most species of other Richardiinae genera by their large size (10‒13 mm) and vespoid shape. Additionally, the genus is characterized by the following combination of characters: prosternum and metasternum bare; postmetacoxal bridge not completely sclerotized; one pair of scutellar setae; all femora robust with spine-like setae on antero- and posteroventral surfaces; wing usually with 1–2 spurious veins (except N. alamagna sp. nov.) on vein R2+3, or free in cell r1; abdomen long and petiolate; cerci of male H-shaped; cerci of female with two modified, flattened apical setae. Generally, the species of Richardiidae have the syntergite 1+2 with preapical setae arranged in rows, when there is more than one seta (except N. alamagna ). However, the species of Neodiotypa have several setae distributed randomly on laterodorsal preapical region of the syntergite 1+2. Additionally, the presence of a flattened apical seta on the cercus of female (Figs. 44, 79, 90) is unique to species of Neoidiotypa and is an autapomorphy of the genus. There are some new species of Cladiscophleps Enderlein from Venezuela, Peru and Argentina (Wendt & Ale-Rocha in preparation) superficially similar to Neoidiotypa by having vespoid shape, wing with anterior half darker than posterior half, abdomen slightly petiolate and tergites with yellow bands at base. However these species and all species of Cladiscophleps are differentiated from the species of Neoidiotypa especially by having the abdomen not strongly petiolate, the syntergite 1+2 with preapical laterodorsal setae arranged in row, the legs densely covered with setulae, and the cerci of female without modified apical seta. Species of Cladiscophleps also have the male cerci Hshaped and the wing generally with two spurious veins on R2+3. Preliminary phylogenetic analysis has showed that these character states represent synapomorphies with Neoidiotypa (Wendt & Ale-Rocha, in preparation).

Distance between ocelli variable among species ( Figs. 106‒111 View FIGURES 106 ‒ 111 ). In lateral view, ventral third of frons slightly protruded, at least one-fourth width of eye (e.g., Figs. 5 View FIGURES 1 ‒ 8 , 38, 49, 76); in frontal view, lateral margins of frons parallel (e.g., Figs. 21 View FIGURES 19 ‒ 28 , 35).

Veins bare. One or two spurious veins present on vein R2+3 (Figs. 39, 62), free in middle of cell r1 ( Figs. 51 View FIGURES 45 ‒ 55 , 77 View FIGURES 72 ‒ 80 ), or spurious vein absent ( Fig. 1 View FIGURES 1 ‒ 8 ). Vein R2+3 straight (e.g., Fig. 39). Apices of veins R4+5 and M1 parallel (e.g., Fig. 32 View FIGURES 29 ‒ 32 ). Crossvein r-m on apical fourth of cell dm. Vein A1+CuA2 long, reaching margin of wing but becoming weaker towards margin (Fig. 40). Alula present. Abdomen: Distinctly or slightly petiolate (e.g., Figs. 8 View FIGURES 1 ‒ 8 , 42, 78) and longer than thorax. Tergites densely covered with setulae. Syntergite 1+2 long, generally 2.0 times longer than tergite 3, narrower than other tergites and with median part slightly thinner than basal and apical portions (e.g., Fig. 52 View FIGURES 45 ‒ 55 ). Sternites without anterior apodemes ( Figs. 91–95 View FIGURES 87 ‒ 95 ). Sternite 1 absent. Sternite 2 elongate, about 5.0 times as long as wide ( Fig. 91 View FIGURES 87 ‒ 95 ). Sternites 3–4 longer than wide ( Figs. 92, 93 View FIGURES 87 ‒ 95 ). Sternites 5 and 6 (in female) wider than long ( Figs. 94, 95 View FIGURES 87 ‒ 95 ). Male terminalia: Abdominal spiracles 6 and 7 present and developed ( Fig. 65 View FIGURES 65 ‒ 71 ). Tergite 6 densely ciliated ( Fig. 65 View FIGURES 65 ‒ 71 ). Cerci slightly sclerotized, developed, H-shaped ( Figs. 68 View FIGURES 65 ‒ 71 , 102 View FIGURES 101 ‒ 105 ). Epandrium wider than long. Lateral surstylus generally slightly longer than medial surstylus; wider on basal half and with rounded sub-basal projection on posterior surface. One prensiseta very strong with pointed apex, on medial preapical margin ( Figs. 10 View FIGURES 9 ‒ 11 , 30 View FIGURES 29 ‒ 32 , 71 View FIGURES 65 ‒ 71 , 105 View FIGURES 101 ‒ 105 ). Distiphallus long and flexible, with two sclerotized ribbons connected by membrane; ribbons densely microsetulose ( Figs. 31 View FIGURES 29 ‒ 32 , 42, 67, 70); apex without modified setae ( Figs. 18 View FIGURES 12 ‒ 18 , 29 View FIGURES 29 ‒ 32 ), with plate slightly ( Fig. 29 View FIGURES 29 ‒ 32 ) or strongly sclerotized ( Fig. 11 View FIGURES 9 ‒ 11 ). Female terminalia: Generally similar among species, apex of cerci varying slightly in shape and width. Cerci with five pairs of apical setae: more basally, 1 ventral and 1 dorsal, long setae; laterally, 2 small preapical setae; and apically, generally 1 modified and flattened apical seta (Figs. 44, 79, 90), except in N. alamagna with pointed and not flattened seta.
