Taxonomic and nomenclatural changes in Cassidinae (Coleoptera: Chrysomelidae) Author Sekerka, Lukáš text Acta Entomologica Musei Nationalis Pragae 2016 2016-07-15 56 1 275 344 journal article 56063 10.5281/zenodo.5305725 31cb15bf-28f5-4b27-86df-6a1b28cbce41 0374-1036 5305725 E24F1028-C6AC-4323-9ED5-C9B7FF3434ACD Charidotella ( Charidotella ) fumosa ( Boheman, 1855 ) Coptocycla fumosa Boheman, 1855: 156 (original description). Metriona obnubilata Weise, 1921: 200 (original description), syn. nov. Type localities. Coptocycla fumosa : ‘Cayenna’. Metriona obnubilata : Brazil , Amazonas, Rio Autáz. Type material examined. Coptocycla fumosa : HOLOTYPE : pinned: ‘ Cayen [w, p, s] || Bhn. [w, p, s] || Type. [w, p, s] || NHRS-SRAH | 000000446 [w, p, cb]’ ( NHRS ). Metriona obnubilata : HOLOTYPE : glued: ‘ Rio | Autaz [w, p, cb] || Amazon | Roman [w, p, cb] || nov. [w, p, s] || Metriona | obnubilata | m. [w, hw by Weise, s] || NHRS-SRAH | 000000474 [w, p, cb] ’ ( NHRS ). Remarks. WEISE (1921) described Metriona obnubilata from a single specimen and compared it to M. glaucovittata ( Erichson, 1847 ) . BOROWIEC (1989) transferred it to Charidotella Weise, 1896 and the taxon was listed only in catalogues (see BOROWIEC 1999a ). The holotype has a pattern on the underside of elytra forming lateral stripe on each elytron and a band across elytra in their basal third. It also has subangulate humeral angles, a diffuse brownish pattern on pronotal disc and the specimen is conspecific with the holotype of C. fumosa . Metriona obnubilata is thus synonymized with the latter species. BOHEMAN (1855) did not state exactly how many specimens he had at his disposal. However, based on the original description and the single length measurement, I assume he had only one. Distribution. Argentina : Tucumán ( SPAETH 1942 ); Brazil : Amazonas ( WEISE 1921 ), Mato Grosso ( SPAETH 1942 ); Ecuador ( BOROWIEC 1996 ); French Guyana ( BOHEMAN 1855 ); Guyana ( BOROWIEC 1996 ); Peru (e.g. SPAETH 1942 , BOROWIEC 1996 ).
