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 Xenochalepus ( Neochalepus ) nigriceps ( Blanchard, 1843 ) Odontota nigriceps Blanchard, 1843 :pl.24, Fig. 9 (original illustration); BLANCHARD (1847) :211 (original description). Chalepus aeneiceps Pic, 1937: 16 (original description), syn. nov. Type localities. Odontota nigriceps : ‘Santa-Cruz ( Bolivia )’; Chalepus aeneiceps : ‘ Brésil : Uberaba’. Type material examined. Chalepus aeneiceps : SYNTYPE : glued, ‘Uberaba | Brésil [w, hw by Pic, s] || Chalepus [w, hw by Pic, s] || Chalepus | aeneiceps | n sp [w, hw by Pic, s] || TYPE [r, p, cb] || Museum Paris | Coll. M.Pic [w, p, cb] || SYNTYPE [r, p, cb] || MNHN | EC2895 [w, p, cb]’ ( MNHN ). Remarks. Odontota nigriceps first appeared as figure on plate published in 1843 while the text description appeared in 1847 ( BLANCHARD 1843 , 1847 ). Its type material is presumably deposited in the MNHN but I was unable to find it during my visit. WEISE (1913) studied additional specimens and transferred it to Xenochalepus Weise, 1910 and this is the generally accepted placement ( UHMANN 1957a , STAINES & RILEY 1994 ). During my stay in the MNHN I examined the syntype of Chalepus aeneiceps and found it has a scutellar row of punctures, which is absent in Chalepus Thunberg, 1805 and in fact belongs to Xenochalepus . Moreover, it is identical to additional specimens identified and published as X. nigriceps and also agrees with the original illustration of that species, and I therefore synonymize C. aeneiceps with X. nigriceps . Distribution. Bolivia : Santa Cruz ( BLANCHARD 1847 , WEISE 1913 , UHMANN 1957b ), Brazil : Minas Gerais ( PIC 1937 ), Paraguay ( UHMANN 1938 ).
