Zeugonota quadrinodosa ( Boheman, 1857)

Desmonota quadrinodosa Boheman, 1857: 25 (original description).

Desmonota plicicollis Boheman, 1862: 64 (original description), syn. nov.

Type localities. Desmonota plicicollis : ‘Brasilia (S:t Paul)’; D. quadrinodosa : not given.

Type material examined. Desmonota plicicollis : SYNTYPE: pinned: ‘ St Paul [g, hw, s] || Type [w, p, s, c, rf] || Ex coll. [hw] | Deyrolle [hw] | Baly Coll. | 1905—54. [w, p, cb] || Desmonota | plicicollis | Boh: | Brazil: merid: [w, hw by Baly, cb] || Type | Boh | Col: Deyrolle [hw by Baly on underside of preceding label]’ ( BMNH).

Remarks. Desmonota plicicollis was listed only in catalogues since its description (see BOROWIEC 1999a) and subsequent authors have not studied its type material. BOHEMAN (1862) described this taxon from the collection of Deyrolle. Most, if not all, taxa of Cassidinae described in the same publication from the Deyrolle’s collection were purchased by J. S. Baly and are nowadays deposited in BMNH. There is a single specimen of D. plicicollis in the latter collection agreeing with the primary description and undoubtedly represents the type. I consider it as a syntype as Boheman did not specifically mention how many specimens he had at his disposal and Deyrolle was a famous insect trader thus additional specimens might exist elsewhere. It is conspecific with Zeugonota quadrinodosa as I am unable to find any morphological differences I synonymize it with the latter species.

Distribution. Brazil: Goias, Minas Gerais, Paraná, São Paulo ( SPAETH 1914, VIANA 1964b).
