Distribution: The beetles, which are usually found in litter, are known from the eastern Mediterranean, East, South-East and South Asia, western North and South America. Larvae unknown. Diagnosis: Lederia is distinguishable from the genera Microscapha LeC, Orchesia Latr. and Hylobia Broun, also members of the tribe Orchesiini, by the total lack of the scutellum (or it is point-like and hardly visible). From the New Zealand genus Lyperocharis Broun the genus Lederia is distinguishable by at least partly developed sutures dividing the metepisterna and metasterna, as well as by the spurs of the metatibiae being shorter than joint 1 of metatarsi (in Lyperocharis the longer of the spurs is slightly longer than the tarsal joint 1). Lederia is apparently most closely related to the genus Eucinetomorphus Perris, but differs from it by the absence of the suture dividing the anterior parts of metacoxae and metathorax, as well as by the very short suture dividing the metepisterna from their sterna, which is at best developed only at the anterior quarter of the metathoracic sides. We had the opportunity to study only one species of Eucinetomorphus, namely E. asturiensis (Rtt.), but according to SEIDLITZ (1898), the above characters seem to be shared by other species of the genus as well. They are members of Lederia s.str. (with L. suramensis and L. arctica) that are apparently especially closely related to Eucinetomorphus, for they have the suture dividing the metepisterna and sterna posterior 1/4 to 2/3 as long as the lateral margin of the metathorax, although the suture dividing the anterior margin of metacoxae and metathorax is always clear. Fuscatelia subgen.n. Type species: Stauropus oviformis Fairmaire et Germain, 1863. Diagnosis: Distinguishable from the other subgenera by a very slightly narrowing outward (not coming to naught) posterior part of the metacoxae (fig. 17), as well as by a dark coloration of the dorsum. The type species, L. oviformis from Chile, is by now the only member of the subgenus. Leder Ina subgen.n. Type species: Lederia kaszabi sp.n. Diagnosis: Characterized by very narrow lateral metepisterna (not less than 5 to 6 times longer than wide), often partly or completely fused with the epimeres, but, unlike the latters, situated ventrally, well visible in ventral view and a little broadened ante riad (fig. 20). Antenna! joint 3 very short and thin, not less than 2.0 to 2.5 times narrower and 2.5 to 3.0 times shorter than 2nd, club 3-jointed, rather well demarcated (fig. 7). Lateral margins of pronotum completely edged. Anterior part of metacoxa rather well narrowing outward to come to naught (fig. 20). Eyes reniform, distinctly emarginated anteriorly. The subgenus contains 8 species: L. foenilis

, L. lata, L. japonica (all from Japan), L. ka szabi sp.n., L. topali sp.n., L. minima sp.n. (all from Vietnam), L. indica sp.n. from India and L. similis sp.n. from Nepal. Macrolederia subgen.n. Type species: Lederia oblonga sp.n. Diagnosis: Metepisterna posteriad roundly narrowed (fig. 18), ca 2.7 to 3.0 times longer than anteriorly wide. Antennái joint 2 distinctly less than twice as wide as 3rd (fig. 8). Lateral margins of pronotum completely edged. Anterior part of metacoxae rather well narrowing outward to come to naught (fig. 18). Characterized by largest (2.3 to 2.7 mm long) body size. Head behind eyes with a transverse carina (fig. 1). Antennae with a poor 4-jointed club (fig. 8). Along middle of male metathorax a rather deep, more or less lanceolate depression with good cariniform edges (Fig. 18). Only L. oblonga sp.n. from Chile, the type species, belongs to this subgenus. Paralederia subgen.n. Type species: Lederia anatolica J. Frivaldszky, 1880. Diagnosis: Characterized by a backwardly narrowing metepisterna usually not less than 3.5 as long as wide, broader than in Lederina subgen.n. Antennái joint 3 usually much broader and elongate than in Lederina subgen.n., less than twice thinner than the 2nd (fig. 40). Lateral margins of pronotum anteriorly not edged. Anterior part of metacoxa rather well narrowing outward
