Cerambyx (Lissonotus) gagatinus Germar, 1824: 504 . Syn. Nov. Rachidion gagatinum ; Audinet-Serville, 1834: 56; Monné, M. A., 2005: 637 (cat.). Rhachidion gagatinum ; Germar in Guérin-Méneville, 1839: 330. Ceroctenus gagatinus ; White, 1853: 58.

The male specimen of Cerambyx (Lissonotus) gagatinus Germar, 1824: 504 , with the labels Brasil, Olfers, (Acc. 17998) ( Figure 1 ), is herein designated as the lectotype ( Figure 1 ) in order to stabilize the taxonomy and facilitate further identifications of this species; 14 male specimens with the same data are herein designated as paralectotypes.

The pattern of coloration of the 14 specimens designated as paralectotypes is highly variable, 7 of them are dorsally shining black, as the lectotype, 2 have the distal half of the elytra ornated with large pale yellow transverse band ( Figure 3 ), 2 with two pale yellow patches, one large triangular in the basal half and a second one transversal in the distal half ( Figure 2 ), and 3 with the elytra partially black and partially reddish brown ( Figure 4 ). Two females ( Figures 5, 6 ), nontypes, are photographed to show the colors patterns.

For nearly 200 years, Cerambyx (Lissonotus) gagatinus Germar, 1824 (today in Rachidion , Cerambycinae , Trachyderini ) remained unidentified. The examination of the 15 male specimens (designated here as lectotype and 14 paralectotypes) allows us to propose the synonymy.

Type material. Lectotype male ( Figure 1 ) (present designation): “ Ceroctenus / Dej.”, “ gagatinus / n. / Lisson g. gm. / Brasil / v. / Olf.” “Zool. / Mus. / Berlin”, “17998” and “ LECTOTYPE / Poekilosoma ornatum ( Dalman, 1823) / des. Monné & Monné 2015” ( ZMHB).

Paralectotypes: 14 males, same labels ( Figures 2–4 ): “Hist. Coll. ( Coleoptera ) / Nr. 17998 / Ceroctenus / gagatinus Germar / Brasil v. Olf. / Zool. Mus. Berlin” and “ PARALECTOTYPE / Poekilosoma ornatum ( Dalman, 1823) / des. Monné & Monné 2015” ( ZMHB).

Material examined. BRAZIL, Rio de Janeiro, Rio de Janeiro, Represa Rio Grande, 1 female, I.1967, F. M. Oliveira col. ( MNRJ); Espírito Santo, Colatina, 1 female, XI.1969, A. Silva col. ( MNRJ).
