Uiblein, T. A. Hoang, Ulysses B. Alama, R. Causse, Osvaldo E. Chacate, Fahmi, S. Garibay, Patroba Matiku","doi":"10.26028/CYBIUM/2018-423-002","DOIUrl":"https://doi.org/10.26028/CYBIUM/2018-423-002","url":null,"abstract":"Goatfishes of the genus Parupeneus (Mullidae), from several areas and countries of the Indo-West Pacific, were studied, focusing on species characterized by a symmetrically rounded rear end of the maxilla, which belong to the so-called heptacanthus group. We examined 62 meristic and morphometric characters and colour patterns from 180 specimens from 11 Parupeneus species, using a comprehensive alpha-taxonomy approach. When possible, the data for species represented by wider size ranges were split into two size classes (small-sized fish, < 110 mm SL, vs. large-sized fish ≥ 110 mm SL) to account for allometric changes in body form. A new species, P. inayatae Uiblein & Fahmi, is described, based on a specimen collected in SW Lom-bok, Indonesia, and new records for four species are reported from the Indian Ocean: Parupeneus fraserorum new for Mozambique, P.jansenii new for Myanmar and the NE Indian Ocean, P. nansen new for Tanzania, and P. procerigena new for the Nazareth Bank and Mauritus (Cargados Carajos Bank), Western Indian Ocean (WIO). The record of P.jansenii for Myanmar was compared in detail to 37 conspecific specimens from the entire distribution range (western Indonesia to Japan and Vietnam to NE Australia). The latter revealed two new Pacific records for the Central Philippines and for Shikoku Island, Japan (northernmost record of the species). For each of the eight heptacanthus-group species, diagnoses are provided along with remarks on intraspecific size- and/or population-related variation and/or other noteworthy observations. The new species can be distinguished from all other 32 congeners as follows: dorsal head margin in front of eyes concave shaped; posterior maxilla margin evenly, symmetrically rounded; body, head, and caudal peduncle moderately deep; pectoral and pelvic fins subequal in length; and caudal peduncle clearly deeper than 9.5 % SL; in life a dusky spot on lateral line below interdorsal space, followed posteriorly by a bright orange blotch. Detailed comparisons among all eight heptacanthus-group species and with three other similar and/or co-occurring congeners revealed considerable similarity between two species pairs, P.jansenii (Eastern Indian Ocean and Western Pacific) and P. nansen (WIO), and P. fraserorum and P. procerigena (both from the WIO). The need to further intensify taxonomie studies and accompanying fisheries-biology and ecological studies of goatfishes in the large realm of the Indo-West Pacific is emphasized.","PeriodicalId":55189,"journal":{"name":"Cybium","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47014444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"What can goby otolith morphology tell us","authors":"Christoph Gierl, D. Liebl, R. Šanda, J. Vukić, H. Esmaeili, B. Reichenbacher","doi":"10.26028/CYBIUM/2018-424-006","DOIUrl":"https://doi.org/10.26028/CYBIUM/2018-424-006","url":null,"abstract":"The taxonomic information inscribed in otoliths has been widely ignored in ichthyological research, especially in descriptions of new fish species. One reason for this is that otolith descriptions are per se qualitative, and only a few studies have presented quantitative data that can support assignments of otoliths to individual species or permit differentiation between higher taxonomic levels. On the other hand, in palaeontology, otoliths have been employed for the identification and taxonomic placement of fossil fish species for over 100 years. However, palaeontological otolith data is generally regarded with suspicion by ichthyologists. This is unfortunate because, in the Cenozoic, the fossil otolith record is much richer than that based on skeletons. Thus fossil otoliths are a unique source of information to advance our understanding of the origin, biogeographical history and diversification of the Teleostei. This case study deals with otoliths of the Oxudercidae, which, together with the Gobiidae, encompasses the 5-branchiostegal-rayed gobiiforms. The objective was to determine whether the five lineages of the Oxudercidae, and individual species of the European Pomatoschistus lineage, could be distinguished based on the quantification of otolith variations. The data set comprises otoliths from a total of 84 specimens belonging to 20 recent species, which represent all five lineages of the Oxudercidae (Mugilogobius, Acanthogobius, Pomatoschistus, Stenogobius, Periophthalmus), and five fossil otoliths of dagger Pomatoschistus sp. (sensu Brzobohaty, 1994). Ten measurements were taken on each otolith and 23 otolith variables were computed and used for univariate and multivariate analyses. The results indicate that otolith morphometry (i) is capable of identifying the Pomatoschistus and Periophthalmus lineages among the Oxudercidae, but is of limited use in the separation of the other three lineages;(ii) can reliably distinguish the sand gobies (a distinct Glade within the Pomatoschistus lineage) from other members of the Pomatoschistus lineage;and (iii) supports a previous assignment of fossil otoliths to dagger Pomatoschistus sp. as an ancient genus of the sand gobies. With its middle Miocene age (15 m.y. ago), dagger Pomatoschistus sp. represents the oldest record of a sand goby species to date. We discuss possible relationships between distinct otolith morphologies, biogeographic distribution and lifestyles for Pomatoschistus and the Periophthalmus lineage, and also for the sand gobies. We conclude that otolith morphology, combined with morphometry, can be considered as an autapomorphy for an individual species from the studied groups. In addition, it also appears to contain a phylogenetic signal, but more work is needed to evaluate this fully.","PeriodicalId":55189,"journal":{"name":"Cybium","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69256408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
