Nisotra chrysomeloides Jacoby, 1885, N. dohertyi (Maulik, 1926), N. gemella (Erichson, 1834), and Nisotra nigripes Jacoby, 1894 are redescribed with illustrations of aedeagi, antennae, gonocoxae, abdominal ventrite VIII, and spermathecae. Nisotra nigripes is recorded for the first time from Taiwan. The immature stages and life history of N. gemella were studied in the laboratory using a novel rearing design. Four synonyms previously proposed are confirmed: Sphaeroderma javana de Motschulsky, 1866, S. orbiculata de Motschulsky, 1866, Nisotra bowringi Baly, 1876, and Podagrica hibisci Bryant, 1941 with N. gemella (Erichson, 1834). Lectotypes are designated for Haltica gemella Erichson, 1834, N. chrysomeloides Jacoby, 1885, N. bowringi Baly, 1876, and Podagrica hibisci Bryant, 1941.
