Genus Metaclisis Förster, 1856 Metaclisis Förster, 1856: 106, 109. Type species Inostemma areolata Haliday, 1835 by monotypy. Parinostemma Kieffer, 1914: 355. Type species Inostemma quinda Walker, 1842 by monotypy and original designation. Parinostemma Kieffer, 1914 – Masner 1965: 131. Remarks Metaclisis was treated by Masner & Huggert (1989). The genus is diagnosable by the fan of striae in the malar space and the forked knob of the submarginal vein in the fore wing. Förster did not recognize these characters, and instead defined it by the number of clavomeres (3, although the number can actually range from 2 to 4) and what he interpreted as a basal fore wing vein (actually a nebulous and pigmented RS&M vein). The type species is Inostemma areolata Haliday, 1835, the lectotype of which is deposited in NMINH. The original exemplar in NHMW is a paralectotype. Förster did not describe any species in Metaclisis. However, Monocrita monheimii Förster, 1861, was later transferred to Metaclisis (Vlug 1973). See section on Monocrita.
