Gorybia bispinosa Martins et al. 2009: 512; Monné et al. 2017: 31 (holotype); Monné 2018: 640 (cat.). Syn. nov. Gounelle (1909) described Haruspex castaneus from Brazil (Goiás), based on a large series of specimens of both sexes (Fig. 21). Martins, 1976, transferred the species to Gorybia Pascoe, 1866, and reported (translated): “I examined a slide of a cotype belonging to the BMNH [The Natural History Museum, London] (J. S. Moure photograph). The great majority of the cotypes must belong to the Gounelle collection (MNHN) [Muséum national d’Histoire naturelle, Paris]; of this collection, I saw 14 topotypes, probably the syntypes, but without labels of identification. A female (MZSP), improperly labeled as syntype, should not belong to the original series; the label of provenance indicates only “ Goiás.” However, Martins (2003) pointed out (translated): “A female syntype, with a green label, handwritten by Gounelle, and recorded in the MZSP under # 16077, where is written: “16077 / Haruspex castnaeus Goun. / Cerambycidae / Gounelle 10, pres. [presente] [gift] Gounelle / Jatahy (Est. Goyaz)”. Martins (1976: 338) affirmed, mistakenly, that this specimen was not a syntype. A second specimen, male, from MZSP, with typical label “Jatahy, Goyaz”, collected by Pujol in XII.1897 – I.1898 also, probably, is another syntype; it has a green label of identification handwritten by Gounelle.” Later, Martins et al. (2009) described G. bispinosa from Brazil (Maranhão), based on a single male. Examination of the holotype (Fig. 22), and specimens of G. castanea (including a syntype), does not reveal differences. The elytral apex in G. castanea is somewhat variable, especially the length of the outer spine of the elytra (Fig. 23–30). Gorybia bispinosa was compared in the original description with G. quadrispinosa. According to the authors, G. bispinosa differs from G. quadrispinosa by the metatibiae not projected at outer apex, and by the absence of smooth area at center of pronotum. Although the tibial shape is not variable in the specimens of Gorybia examined by us, the smooth area at center of pronotum may or may not be present, with gradations between the two extremes. All of which supports placement of Gorybia bispinosa Martins as a synonym of Gorybia castaneus Gounelle. Material examined. All from MZSP.
