Diabrotica tripunctata ( Fabricius, 1801) status restored

( Figs 72–74 )

tripunctata Fabricius 1801: 451 (type locality: America meridionalis; type depository: ZMUC, lectotype, female, designated by Smith and Lawrence 1967: 135, examined) as Crioceris .

Material examined: Lectotype female ( ZMUC): 1) [ TYPE]; 2) [C: tripunctata ex Am: mer: Schmid]; 3) [Lectotype. Crioceris 3punctata Fabr. Smith 1965]. Three females ( ZMUC): 1) [ TYPE]; 2) [Paratype. Crioceris 3punctata Fabr.]. One female from Kiel collection ( ZMUC): [3punctata].

This species has long been considered part of the melanocephala complex ( Bechyné 1955b, Smith and Lawrence 1967) and treated as a synonym of D. sinuata (Olivier) ( Wilcox 1971) . We studied the type material of D. tripunctata (Fabricius) in ZMUC. The lectotype is a female, but all external characters distinguish it from D. sinuata : penultimate joint of maxillary palpi slightly incrassate in D. tripunctata , but not incrassate in D. sinuata ; elytra longer and narrower (the maximal width is posterior to the middle of the elytra) in D. tripunctata , but shorter and more roundish (the maximal width is at the middle of the elytra) in D. sinuata ; pronotum slightly flattened in D. tripunctata , but convex in D. sinuata ; elytral punctation coarse and deep ( Fig. 74 ), punctures around scutellum connected in rough wrinkles in D. tripunctata , but surfaces of elytra and pronotum are shiny in D. sinuata .
