Scaphoidella is among the most common and widespread genera of deltocephaline leafhoppers in the temperate and tropical regions of the eastern Palearctic and mainland southeast Asia. Seventeen species are recognized, including nine new species from Thailand (S. lamellan. sp., S. flangenellan. sp., S. coronoidan. sp., S. bifurcatan. sp., S. cornutan. sp., S. viraktamathin. sp., S. clavatellan. sp., S. dimidiatusn. sp., S. digitatusn. sp.), and one new species from Vietnam (S. dongnaiensisn. sp.). Three new combinations are proposed: Scaphoidella zhangi (Viraktamath & Mohan 2004) n. comb. and Scaphoidella punctulata (Melichar 1903) n. comb., (both transferred from Scaphoideus); and Monobazus datianensis (Xing, Dai & Li 2008) n. comb. (transferred from Scaphoidella). Two species are recorded from Thailand for the first time: Scaphoidella zhangi (Viraktamath & Mohan 2004) and S. wideaedeaga (Li & Wang 2004). Scaphoidella transversa Li & Xing is excluded from Scaphoidella and treated as a species incertae sedis. Detailed morphological descriptions and illustrations of ten species are given and a checklist and key for all known species of the genus are provided. Comparative notes on the related genera Scaphomonus Viraktamath, Melanetettix Knight & Fletcher, and Allotapes are provided, along with a discussion of the application of the morphological term “paraphyses” to leafhopper genitalia.
