Abstract
A new megabalanine barnacle, Austromegabalanus carrioli sp. nov., is described from lower Miocene strata of the Chilcatay Formation (East Pisco Basin, southern Peru). An assessment of the value of interlaminate f gures in distinguishing species within the tribe Austromegabalanini from thin sections is provided – a useful identif cation tool with fossil taxa such as the austromegabalanines, which are commonly found only as fragmented shells. The paper concludes with a reassessment of the palaeobiogeography and distribution patterns of the austromegabalanines, proposing a circum-equatorial origin for this tribe.

The authors are very grateful to CLAUDIO DI CELMA (Uni-versità di Camerino) and ELISA MALINVERNO (Università di Milano-Bicocca) for their invaluable help during f eld-work in the East Pisco Basin and assistance during the preparation of the manuscript. The support of LUCA FAL-LATI (Università di Milano-Bicocca) was important in the f rst phases of preparation of the thin sections. SYLVAIN CHARBONNIER (Muséum National d’Histoire Naturelle) and MARCO DELLACASA (Museo di Storia Naturale, Università di Pisa) provided access to the megabalanine material under their care and loan of specimens for comparison purposes. WILLIAM A. NEWMAN (Scripps Institution of Oceanography) is kindly acknowledged for fruitful discussions on the taxonomy of Megabalaninae. Constructive comments by two anonymous reviewers and GüNTER SCHWEIGERT (Staatliches Museum für Naturkunde Stuttgart) substantially contributed to shape this work in the present form – thank you very much! Fieldwork by ALBERTO COLLARETA , GIULIA BOSIO , and GIOVANNI BIANUCCI in the East Pisco Basin was supported by a grant from the Italian Minis-tero dell’Istruzione, dell’Università e della Ricerca [PRIN Project, 2012YJSBMK] to GIOVANNI BIANUCCI , CLAUDIO DI CELMA , and ELISA MALINVERNO , and by a grant by Uni-versità di Pisa to GIOVANNI BIANUCCI [PRA_2017_0032].
