Type material

Holotype: UFPB PYC-242 (not examined). Type locality: Jericoacoara , Ceará, Brazil.

Remarks

The specimens were mistakenly listed as Anoplodactylus stictus Marcus, 1940 in Sabroux et al. (2019b). The distance between the lateral processes and the shape of proboscis extensions (alar rather than cordiform) do not match the descriptions in Marcus (1940) or Lucena & Christoffersen (2018b). The specimens from Martinique greatly resemble the description of Anoplodactylus ganchiformis Lucena & Christofersen, 2018 from Brazil, including the conical ocular tubercle, the more elongated trunk relative to other species of the Anoplodactylus californicus-digitatus species complex of Arango & Maxmen (2006), the shape of all the processes and the hook at the base of the third article of the oviger. The dorsodistal tubercles of the lateral processes are, however, much lower in Martinique specimens.

The specimen MNHN-IU-2016-1413 shows two differences compared to the other specimens assigned to A. ganchiformis : it is slightly more elongated and has completely inconspicuous lateral processes on the dorsodistal tubercles. No CO1 data could be sequenced for this specimen.

All these specimens were collected on ship hulks in the Baie de Fort-de-France.

Ditribution

Previously recorded in Brazil, and now in Martinique.
