BOLETIM DO MUSEU NACIONAL NOVA SÉRIE RIO DE JANEIRO - BRASIL ISSN 0080-312X ZOOLOGIA o N 507 11 DE AGOSTO DE 2003 ON THE VALIDITY OF FOUR LITTLE-KNOWN SPECIES OF VERRUCIDAE (CRUSTACEA, CIRRIPEDIA) FROM AZORES REGION 1 (With 7 figures) PAULO S. YOUNG 2 ABSTRACT: Four little-known species of Verrucidae from the Azores region are reevaluated after examining the type series: Verruca joubini Gruvel, 1912 and Verruca inermis Aurivillius, 1898 are valid and redescribed, the former included in the genus Altiverruca and the latter in Metaverruca. Verruca grimaldii Gruvel, 1912 is here considered a synonym of Costatoverruca cornuta (Aurivillius, 1898). The type series of Verruca crenata Aurivillius, 1898 did not include mature specimens, and the young specimens examined cannot be recognized as a distinct species separable from other Altiverruca. Lastly, the record by GRUVEL (1920) of V. stroemia (Müller, 1776) from depth of 2600m is rejected. Key words: Crustacea, Cirripedia, Verrucidae, Taxonomy, Azores. RESUMO: Sobre a validade de quatro espécies pouco conhecidas de Verrucidae (Crustacea, Cirripedia) da região dos Açores. Quatro espécies pouco conhecidas de Verrucidae da região dos Açores são reavaliadas através do estudo de suas series-tipo: Verruca joubini Gruvel, 1912 e Verruca inermis Aurivillius, 1898 são reconhecidas como válidas e são redescritas, a primeira incluída no gênero Altiverruca e a última em Metaverruca. Verruca grimaldii Gruvel, 1912 é considerada sinônima de Costatoverruca cornuta (Aurivillius, 1898). A série-tipo de Verruca crenata Aurivillius, 1898 não apresenta espécimens desenvolvidos e os jovens examinados não podem ser diferenciados de outras espécies de Altiverruca. Além disso, o registro de GRUVEL (1920) da profundidade de 2600m para V. stroemia (Müller, 1776) é rejeitada. Palavras-chave: Crustacea, Cirripedia, Verrucidae, Taxonomia, Açores. INTRODUCTION GRUVEL (1920) recognized 13 species of verrucid collected during the Campagnes Scientifique de SAS Le Prince de Monaco (1885-1913). His study included the redescription in detail of seven species briefly described by AURIVILLIUS (1898) and redescription of three others (GRUVEL, 1900; 1912). Seven of these species are currently recognized and they have been referred to subsequent authors, viz, Verruca cornuta Aurivillius, 1898 (= Costatoverruca Young, 1998), Verruca quadrangularis Hoek, 1883 (= Altiverruca Pilsbry, 1916), Verruca aequalis Aurivillius, 1898 (= Metaverruca Pilsbry, 1916), Verruca recta Aurivillius, 1898 (= Metaverruca), Verruca spengleri Darwin, 1854, Verruca trisulcata Gruvel, 1900 (= Metaverruca), Verruca stroemia Müller, 1776 (BUCKERIDGE, 1994; 1997; YOUNG, 1998a, 1998b; 2001). 1 Submitted on May 20, 2002 Accepted on October 8, 2002. 2 Museu Nacional/UFRJ, Departamento de Invertebrados. Quinta da Boa Vista, São Cristóvão, 20940-040, Rio de Janeiro, RJ, Brasil. 2 P.S.YOUNG Verruca sculpta Aurivillius, 1898, is currently recognized as a synonym of Metaverruca recta (BUCKERIDGE, 1994). Verruca costata Aurivillius, 1898 (= Gibbosa verruca Young, 2002) was recorded from the Mediterranean and Eastern Pacific (MACDONALD, 1929; ROSSI, 1958). Four species have never been cited again despite extensive collections taken in the Azores region, these are: Verruca grimaldii Gruvel, 1912 (= Costatoverruca), Verruca joubini Gruvel, 1912 (= Altiverruca), Verruca crenata Aurivillius, 1898 (= Cristallinaverruca Young, 2002), and Verruca inermis Aurivillius, 1898 (= Altiverruca). To verify the validity of these four species, the type series were examined and the results are presented below. Furthermore, due to the unusual deep-water record of specimens of Verruca stroemia (Müller, 1776), this sample was also reexamined. Unless otherwise noted all of the specimens were collected by the vessel S.A.S. Le Prince de Monaco. Abbreviation: (rc) rostro-carinal diameter.

He described briefly this species and commented it was similar to Altiverruca erecta (Gruvel, 1900). This species was not reported again. Reviewing the typeseries of Altiverruca erecta (in YOUNG, 2002b) and A. joubini, it is possible to clearly differentiate both (Tab.2). And, due to these differences, I have to consider the specimens I identified (YOUNG, 1998c) as Altiverruca erecta from Mid-Atlantic Ridge (15º35,33’N, 46º45,06’W, 3947-3375m) to be A. joubini. Therefore, A. joubini is valid and known from two localities in the North Atlantic. c 0.3mm 0.2mm b 0.3mm 0.3mm a d Fig.3- Altiverruca joubini (Gruvel, 1912), lectotype: (a) cirrus I; (b) cirrus II; (c) median article of cirrus VI; (d) protopodite of cirrus VI, penis and caudal appendage.

This material, in addition to one specimen from station 1311, was examined by GRUVEL (1920). After that, this species was never recorded again. Based on their descriptions, YOUNG (1998a; 2002a) included this species in Altiverruca, commenting that the opercular plates formed an obtuse angle with the vertical plane. All three specimens were reexamined and the one from station 616 was selected as lectotype. But both samples were badly preserved, and lacked several wall plates. The type series (station 616) consists of only empty shells, the opercular plates and body having been lost and the specimen from station 1311 is missing the tergum, and the fixed-tergum. Therefore, the redescription presented above was based on the shells of the type series, the appendages and scutum from the specimen of station 1311, and the tergum based on the figure of GRUVEL (1920:pl.6, fig.3). a c 0.2mm 0.2mm 0.2mm b d 0.2mm e 0.2mm Fig.5- Metaverruca inermis (Aurivillius, 1898), station 1311: (a) labrum and palp; (b) palp; (c) mandible; (d) maxilla I; (e) maxilla II. These specimens have to be reasigned to the genus Metaverruca because the shell is box-like, and the opercular plates situated in plan view parallel to the base, the fixed scutum has a wall developed adductor ridge, and the base of the shell is thickened. Metaverruca inermis is similar to M. recta (Aurivillius, 1898); its shell is Bol. Mus. Nac., N.S., Zool., Rio de Janeiro, n.507, p.1-13, aug.2003 10 P.S.YOUNG smooth, not forming elevated ridges and the margin for the base of the opercular plates is straight. Otherwise, their appendages are similar. But, M. recta has the rostro-carinal suture imbricated, both plates have several articular ridges, the number of articular ridges on the tergum is only three, and it has three pairs of setae on the anterior margin of intermediate articles of cirrus VI. 0.3mm 0.5mm c 0.5mm 0.5mm a d b Fig.6- Metaverruca inermis (Aurivillius, 1898), station 1311: (a) cirrus I; (b) cirrus II; (c) median article of cirrus VI; (d) protopodite of cirrus VI and caudal appendage.

Material examined – Type series: Azores, station 584, 38°31’N, 20°09’30”W, 845m (AURIVILLIUS, 1898). Remarks – The type series consists only of fragments or small specimens that do not possess the characters described in the diagnosis of AURIVILLIUS (1898) and GRUVEL (1920:42, pl.6, figs.4-5). The juveniles can be included in any species of Altiverruca s. l. and therefore, the validity of this species cannot be verified. Bol. Mus. Nac., N.S., Zool., Rio de Janeiro, n.507, p.1-13, aug.2003 12 P.S.YOUNG Genus Verruca Schumacher, 1817 Verruca stroemia (Müller, 1776) Material examined – Station 2354, no lat, 2600m, 21 specimens, rc: 1.2 to 5.7mm. Remarks – GRUVEL (1920:50) noted that some specimens of Verruca stroemia from station 2354, no lat, were collected from 2600m (probably label error). This is an unusual bathymetric occurrence, because the species is commonly found in depths shallower than 200m. Although my study of this sample confirms that the specimens are actually V. stroemia, the substrate where they were taken suggests that the sample was mislabeled. Most Verruca have settled on crusts of calcareous algae that does not occur deeper than 100m. Therefore, the depth record of 2600m for V. stroemia has to be rejected.
