Three new species of the genus Dendronotus are described from the North Pacific waters of Japan and Russia. For the first time since 1949, three new species, D. jamsteci sp. nov., D. zakuro sp. nov. and D. bathyvela sp. nov. are described from the waters of the Japanese Islands. D. zakuro sp. nov. was also discovered in the waters of Russia (Kamchatka). The descriptions of the new species D. jamsteci sp. nov. and D. zakuro sp. nov. are based on morphological and molecular data; D. bathyvela sp. nov. morphologically belongs to the group of D. robustus, D. velifer and D. patricki. This study revises our knowledge of North Pacific species of the genus Dendronotus, considerably expands the number of species worldwide and contributes to the multilevel fine-scale diversity concept.

Combining morphological and molecular data in an integrative approach, three new mayfly species of Epeorus (Caucasiron) are described. These include Epeorus (Caucasiron) alborzicus Hrivniak & Sroka, sp. nov. and Epeorus (Caucasiron) shargi Hrivniak & Sroka, sp. nov. from northern Iran, and Epeorus (Caucasiron) zagrosicus Hrivniak & Sroka, sp. nov. from central Iran. They are unambiguously delimited using both distance-based and likelihood-based approaches in the analyses of barcode COI sequences. Each new species is compared with other species of the subgenus and morphological diagnostic characters are provided. Based on extensive sampling of streams throughout the country, the distribution and habitat preferences of all Caucasiron species in Iran are assessed. Altogether, there are now six species recorded, among them also E. (C.) nigripilosus Sinitshenkova, 1976 is reported for the first time in Iran. Five species are distributed in the Alborz Mts. in northern Iran, one species was found in the Zagros Mts. in central Iran.

Three new species of antipatharian corals are described from deep-sea (677–2,821 m) seamounts and ridges in the North Pacific, including Antipathes sylospongia, Alternatipathes venusta, and Umbellapathes litocrada. Most of the material for these descriptions was collected on expeditions aboard NOAA Ship Okeanos Explorer that were undertaken as part of the Campaign to Address Pacific Monument Science, Technology, and Ocean Needs (CAPSTONE). One of the main goals of CAPSTONE was to characterize the deep-sea fauna in protected waters of the U.S. Pacific, as well as in the Prime Crust Zone, the area with the highest known concentration of commercially valuable deep-sea minerals in the Pacific. Species descriptions and distribution data are supplemented with in situ photo records, including those from deep-sea exploration programs that have operated in the North Pacific in addition to CAPSTONE, namely the Hawaii Undersea Research Laboratory (HURL), the Ocean Exploration Trust (OET), and the Monterey Bay Aquarium Research Institute (MBARI).

The Relationship

Morphological and molecular data are presented for the first time in an integrative way for the genus Myja Bergh, 1896. In accordance with the new molecular phylogenies, the traditional Facelinidae is paraphyletic. Herein is presented the phylogenetic placement of true Facelinidae s. str., including the first molecular data for F.auriculata (Müller, 1776), type species of the genus Facelina Alder & Hancock, 1855. The taxonomic history of F.auriculata is reviewed. The genus Myja is related to the clade Facelinidae s. str., but shows disparate morphological traits. Two new species of the genus Myja, M.karinsp. n., and M.hyotansp. n., are described from the Pacific waters of Japan (middle Honshu), and M.cf.longicornis Bergh, 1896 is investigated from Thailand. According to molecular analysis and review of available morphological information, the genus Myja contains more hidden diversity. The family-level relationship within aeolidacean nudibranchs with emphasis on the family Facelinidae is outlined. The problem of the relationship between Facelinidae Bergh, 1889 and Glaucidae Gray, 1827 is discussed. The family Glaucidae has precedence over Facelinidae and is phylogenetically related to the core group of Facelinidae s. str., but has a profoundly modified aberrant external morphology, thus making a purely molecular-based approach to the taxonomy an unsatisfactory solution. To accommodate recently discovered hidden diversity within glaucids, the genus Glaucilla Bergh, 1861 is restored. The family Facelinidae s. str. is separate from, and not closely related to, a clade containing the genera Dondice Marcus, 1958, Godiva MacNae 1954, Hermissenda Bergh, 1879, and Phyllodesmium Ehrenberg, 1831 (= Myrrhine Bergh, 1905). The oldest valid available name for the separate ex-facelinid paraphyletic clade that contains several facelinid genera is Myrrhinidae Bergh, 1905, and resurrection of this family name under provision of the ICZN article 40.1 can preliminarily solve the problem of paraphyly of the traditional Facelinidae. “Facelinidae” s. l. needs to be further divided into several separate families, pending further study.

The ‘aegrota species group’ of the Neotropical nymphalid genus Caeruleuptychia Forster, 1964, in addition to three other superficially similar, enigmatic species in the genus, are revised. A lectotype is designated for Euptychia aegrota Butler, 1867, E. aetherialis Butler, 1877 stat. rev., E. helios Weymer, 1911 and E. pilata Butler, 1867, and C. aetherialis is resurrected from its synonymy with C. aegrota. Caeruleuptychia helios caelestissima Brévignon, 2010, syn. nov., and Magneuptychia keltoumae Brévignon & Benmesbah, 2012, syn. nov. are both regarded as junior subjective synonyms of C. helios (Weymer, 1911), as a result of the discovery and first illustration of the female of this taxon. The female of C. aegrota is also described and illustrated for the first time, and three new species, C. trembathi Willmott, Nakahara, Hall & Neild, sp. nov., C. scripta Nakahara, Zacca & Huertas, sp. nov., and C. maryzenderae Lamas & Nakahara, sp. nov. are described and named. We analyze morphological and molecular data separately, in addition to combining morphological data with molecular data, to provide the first phylogenetic hypothesis for the taxa treated in this revision.

Pangrapta Hübner, 1818 was erected for the North American species P. decoralis Hübner, 1818 as its type species. The genus Pangrapta presently consists of about 100 species, and is widely distributed in China and surrounding regions, as well as in the New World (Hu & Wang, 2013). In this article, three new species, P. nanlingensis sp. n., P. jianfenglingensis sp. n. and P. hainanensis sp. n., are described from China. Each of them is superficially similar to the species, P. neorecusata (Hu & Wang, 2013), P. perturbans (Walker, 1858) and P. pannosoides (Holloway, 2005), correspondently. The known Southeast Asian species, P. shivula (Guenée, 1852), is reported for the first time from China. Adults and genitalia are illustrated. The type series of all described species (including holotypes) are deposited in Southwest University of Science and Technology (SWUST), Mianyang, China.

Two new species of Cumella (Cumacea: Nannastacidae), C. oculata and C. alaskensis are described from shallow Alaskan rocky shores. The new species C. oculata can be distinguished from other North Pacific Cumella by the combination of a large eye lobe, no spines dorsally on the carapace, and carapace without large tubercles. The new species C. alaskensis can be distinguished from the other North Pacific Cumella by the 5 spines distributed unequally on the dorsal crest.
