Type species: Pedinotus brasiliensis Szépligeti, 1902

Redescription of the genus. Head usually not depressed, transverse. Ocelli arranged in triangle with base more or less larger than its sides. Frons usually weakly concave, with narrow and often short median keel in anterior half and/or between antennal sockets. Vertex often glabrous and smooth, less often setose and sometimes striate or rugose. Eyes virtually glabrous. Occipital carina dorsally complete, obliterated below above hypostomal carina. Malar suture absent. Clypeus with short lower flange. Hypoclypeal depression medium-sized and subrounded. Postgenal bridge narrow. Maxillary palpi long, 6-segmented, sixth segment about as long as fifth segment; labial palpi rather short, 4-segmented, its third segment not shortened. Antenna slender, weakly setiform. Scape wide and short, without apical lobe and basal constriction, its dorsal margin (lateral view) longer than ventral margin. First flagellomere subcylindrical, not curved outer, usually more or less longer than second flagellomere, rarely equal to or shorter than second flagellomere. Apical flagellomere pointed apically and with more or less distinct spine.

Mesosoma usually not depressed. Neck of prothorax short. Pronotum dorsally more or less distinctly convex, its anterior flange medium size and curved up; pronotal carina fine or distinct, usually in submedian position. Propleural lateroposterior flange rather long and wide. Mesonotum highly and perpendicularly or roundly elevated above pronotum (lateral view), widely setose or mainly glabrous, densely punctate or rugulose-punctate with granulation, but often mainly smooth. Median lobe of mesonotum (dorsal view) mainly without median longitudinal furrow or depression, but sometimes without furrow at least posteriorly, without anterolateral corners. Notauli deep anteriorly and shallow or very shallow posteriorly, almost complete, rather wide. Tegula distinctly widened distally, usually weakly concave along posterior margin. Prescutellar depression short, with several distinct carinae. Scuto-scutellar suture distinct. Lateral longitudinal wing-like flanges on level of prescutellar depression distinct, but rather low. Scutellum more or less weakly convex, usually without lateral carinae. Metanotum with distinct or short thick median tooth. Precoxal sulcus (sternaulus) present and more or less sculptured, but often shallow to very shallow or almost indistinct and smooth. Prepectal carina distinct and rather wide below, laterally weak and prolongate usually till lower margin of subalar depression or upper margin of precoxal sulcus (sternaulus). Postpectal carina absent. Metapleural flange rather long, narrow or rather wide, rounded or subpointed apically. Propodeum with indistinct or distinct areas delineated by fine or coarse carinae at least partly, often mixed with rugosity; areola (if present) medium size or large; lateral tubercles absent or sometimes short and thick, propodeal bridge absent. Propodeal spiracles subround or weakly oval.

Wings. Pterostigma of fore wing rather wide. Vein r (first radial abscissa) arising usually from or before middle of pterostigma. Radial (marginal) cell not shortened. Veins 2RS and r-m (first and second radiomedial) present. Vein m-cu (recurrent) more or less weakly antefurcal. Vein 1cu-a (nervulus) straight and usually postfurcal. First discal (discoidal) cell petiolate anteriorly, vein 1RS (petiole) short and sometimes thickened. Vein 2CUb (parallel) arising from posterior 0.3–0.4 of apical margin of brachial cell. First subdiscal (brachial) cell always closed postero-apically by vein 2cu-a (brachial). Vein 2cu-a (brachial) rather long and directed towards base of wing (reclivous). Veins 1a and 2a (first and second transverse anal) absent. Hind wing always with three hamuli. Vein C+Sc+R (first costal abscissa) 0.8–1.0 × as long as vein SC+R (second costal abscissa). Marginal (radial) cell subparallel-sided, without vein r (additional transverse). Basal (medial) cell narrow, weakly widened towards apex, 10.0–15.0 × longer than width, about 0.4 × as long as hind wing. Vein cu-a (nervellus) present and inclivous. Subbasal (submedial) cell short. Vein M+CU (first abscissa of mediocubital) 0.25–0.40 × as long as vein 1M (second abscissa). Vein m-cu (recurrent) rather short, strongly oblique toward base of wing (reclivous), mainly sclerotised.

Legs. Fore tibia with several rather long and thick spines arranged in single line or narrow stripe. Fore tarsus 1.3–1.5 × longer than fore tibia. Mid tibia with several short and thick spines arranged in almost single line situated more closely to dorsal margin of tibia. Hind coxa high and usually short, with basoventral corner and distinct basoventral tubercle. All femora without or with very low dorsal protuberances. Hind tibia with comb of five-seven spines on its apical outer margin. Hind tibial spurs rather short and weakly curved; its inner spur without inner median expansion. Basitarsus of hind tarsus 0.7–0.9 × as long as second-fifth segments combined. Claws short, wide and simple.

Metasoma. First tergite not petiolate, wide, usually short or sometimes elongated. Acrosternite of first segment short, about 0.15 × as long as first tergite. Dorsope of first tergite large; laterope absent; basolateral lobes absent; spiracular tubercles usually absent, spiracles situated in basal 0.3 of tergite; dorsal carinae often distinct in basal half only. Second tergite with narrow or sometimes wide, distinct or rarely fine, subparallel or weakly divergent or rarely convergent posteriorly sublateral furrow fused with breaks (curves) of second suture; with short and wide, distinctly separated additional subtriangular basolateral areas. First and second tergites often immovably fused (lateral view), but sometimes not fused. Suture between second and third tergites deep, rather wide; distinctly or strongly curved medially, usually with strong or distinct sublateral breaks (curves). Third tergite with complete, deep, usually wide and often curved laterally transverse subbasal furrow. Second-sixth tergites with separate laterotergites. Third-sixth tergites in their middle with transverse line of short and sparse pale setae. Ovipositor apically with two obtuse and distinct dorsal nodes. Ovipositor sheath long. In male, metasoma distinctly transformed ( Rhaconotus -shaped): fourth-sixth tergites strongly sclerotised, distinctly convex, entirely sculptured, with deep and crenulated transverse basal furrow; sixth tergite enlarged, covered following tergites.

Diagnosis. Pedinotus is very similar to the Neotropical Hybodoryctes Szépligeti , but differs from it in the following characters: the second metasomal tergite without basal area (with delineated basal area in Hybodoryctes ), metasoma behind second tergite usually distinctly sculptured at least in basal third or quarter (entirely smooth in Hybodoryctes ), and vein 1cu-a (nervulus) more or less distinctly postfurcal (interstitial in Hybodoryctes ).

Hosts. Unknown.

Distribution. Neotropical and Oriental Regions.
