Type species: Leptophysoderes orellana Weirauch, 2006

Revised diagnosis of Leptophysoderes (white arrowheads in figures): Recognized among Physoderinae by the small size and slender habitus in the male (4.6–5.2 mm) [ Figs 1–4 ] and fairly small size and elongate-ovoid habitus in the female (5.4–5.6 mm) [ Figs 28–32 ], long second labial segment and relatively stout third labial segment ( Figs 4 , 30, 31 ), scapus reaching clypeus ( Figs 7 , 35 ), the anterior pronotal lobe in males narrow, only ~2/ 3 width of the posterior lobe ( Fig. 10 ), absence of paramedian carinae ( Figs 10 , 39 ), absence of parascutellar lobes on the posterior pronotal lobe ( Figs 1, 2 , 10 , 28, 29 , 39 ), slender and dorsally rounded apex of the scutellum ( Figs 11 , 29 ), legs slender ( L. orellana ) or slightly (male) to moderately (female) incrassate ( Figs 1–4 , 12 , 28–32 ) pro- and mesofemora with ( Figs 12 , 30 ) or without ( L. orellana ) ventral spines, pro- and mesotibiae without processes ( L. orellana ) or with small ( Fig. 13 ) or large ( Fig. 41 ) setigerous processes, all tarsi with two tarsomeres ( Figs 31 , 45 ), apex of corium rounded ( Figs 17 , 46 ), and Cu in the hemelytral membrane either present ( Fig. 17 ) or absent ( L. orellana ), if present M and Cu close to each other at corium-membrane boundary ( Fig. 17 ).

Distinguished from the only other Physoderinae known from the Neotropical Region, Cryptophysoderes Wygodzinsky and Maldonado, by the longer second labial segment and the stout third segment, the scapus reaching or surpassing the clypeal apex, the absence of parascutellar lobes and paramedian carinae on the pronotum, and the rounded apex of the corium.
