New genus and two new species of driftwood hoppers (Crustacea, Amphipoda, Talitridae) from northeast Atlantic and Mediterranean coastal regions Author Wildish, David J. text Zoosystematics and Evolution 2014 90 2 133 146 http://dx.doi.org/10.3897/zse.90.8410 journal article http://dx.doi.org/10.3897/zse.90.8410 1860-0743-2 Taxon classification Animalia Amphipoda Talitridae Macarorchestia martini Stock, 1989 Macarorchestia martini : Stock 1989 : 1109. Material examined. Male holotype and 8 females (allotype and paratypes) on loan from Zoological Museum of Amsterdam, Amsterdam, the Netherlands (AMPH. 108.57). Collected by J. Stock on 2 August, 1987 from Gruta das Agulhas in Porto Judeus on the island of Terceira, Azores archipelago. Distribution. Known only from the type locality on the island of Terceira. Epidermal pigment patterns. Not mentioned by Stock (1989) . Remarks. This is the type species and smallest Macarorchestia . Stock (1989) was equivocal about whether this was a recent troglobiont specialist or trogloxenous form. I concur with the latter view and believe that the adaptations (small body length, body length greater in the female, small eyes, reduced pleopod rami and shortened length of the first 5 peraeopods) indicate that Macarorchestia martini is a driftwood specialist.
