The new subspecies, Tetartostylus pavaholatus spiniis, is described, Balclutha frontalis Ferrari is reinstated as valid, and nine replacement names are given: Balclutha flavidella, Cephalius villiersi, Exitianus evansi, Hecalus chilensis, Macropsis ishiharai, Scaphytopiiis delongi, Scaphytopius {Cloanthanus) linnaviioni, Sorhoanus ///, and Thantnotettix matsunturai. Additionally, the principle of first revisor is applied to fix the correct spellings of 13 species spelled multiple ways within their original descriptions. Key Words: Membracoidea, leafhopper, new names, subspecies, nomenclature Inconsistency often becomes apparent when one brings together many dispa-rately published species into a single classification. Although no single classifi-cation is likely to please all researchers, due to inherent subjectivity, all names used in classifications must meet the requirements of the International Rules of Zoological Nomenclature (ICZN; In-ternational Commission on Zoological Nomenclature 1999). While preparing the Leafhoppers of the World Database (LOWD), we discovered many changes needed purely on nomenclatural grounds. Necessary replacement names for pre-occupied leafhopper genera already were provided recently, along with consequent new species combinations (Seven 1997; McKamey 2003, 2006; Dmitriev and Dietrich 2006). The first paper dealing with purely species-level changes uncov-ered while compiling LOWD dealt with the subfamily Cicadellinae (McKamey 2006). This paper, the second install-ment, is on the Deltocephalinae and Macropsinae. The limits of Macropsinae are not in dispute. The limits of Deltocephalinae, however, have been variably defined (Metcalf 1967a, b; Hamilton 1975; Oman et al. 1990) to sometimes include several taxa that are otherwise treated as sepa-rate subfamilies, such as the Aphrodinae. Even in the most restricted sense, as applied here, Deltocephalinae is the largest subfamily of leafhoppers, con-taining about 5,400 species. They are cosmopolitan and many are known to transmit phytopathogens, such as reo-viruses and rhabdoviruses (Conti 1985).
