Dorynota (Dorynota) nigra ( Boheman, 1856) ( Figs. 21–22 , 45 )

Batonota nigra Boheman, 1856: 93 (type locality: ‘Peruvia’).

Type Material Examined. Lectotype (designated by Borowiec 1999), pinned: ‘ Peru [w, p, cb] ∥ Deyrolle [w, p, cb] ∥ Type. [w, p, cb] ∥ Lectotype ∣ des. L. Borowiec [r, p, cb]’ ( SMNH). Paralectotype, pinned: ‘ Peru [g, hw, cb] ∥ Type ∣ C: Deyrolle [w, J. S. Baly’ s hw, cb] ∥ Type [w, p, s, circle label with red frame] ∥ Peru. [hw] ∣ ex Deyrolle [hw] ∣ Baly Coll. ∣ 1905—54. [w, p, cb] ∥ Batonota ∣ nigra, Bhn ∣ Type! [w, C. J. Gahan’ s hw, cb]’ ( BMNH).

Additional Material Examined (1). COLOMBIA: Arauca: Tame, 21.–29. VI .1976, M. Cooper lgt. (1 specimen, BMNH) .

Diagnosis. Dorynota nigra is a well-characterized species, the only one of the nominate subgenus with elytra with a metallic tint. The similarly dark colored D. bidens differs in that the elytra are dull black without a metallic tint and the dorsal spine is longer.

Remarks. Boheman (1856) did not state how many specimens he examined. However, we can assume he had at least two, as he provided two localities in his description and also described var. a. Borowiec (1999) examined the specimen in SMNH and designated it as a lectotype. We recently examined another specimen from the Baly collection (ex. Deyrolle material) deposited in the BMNH, which thus becomes a paralectotype according to the Code ( ICZN 1999). The typical form was described from Peru, while the variants are from Caracas. The types were almost certainly mislabeled and only the locality for the variants is correct, as we do not know of any other specimens of this species from Peru, and the species seems to be restricted to the northern coast of South America.

Distribution. Trinidad and Venezuela (Aragua, Distrito Federal) (Borowiec and Świętojańska 2014). New country record for Colombia ( Fig. 45 ).
