The horseshoe crab Limulus polyphemus (Linnaeus, 1758) is a famous species, renowned as a ‘living fossil’ (Owen, 1873; Barthel, 1974; Kin and Błażejowski, 2014) for its apparently little-changed morphology for many millions of years. The genus Limulus Müller, 1785 was used by Leach (1819, p. 536) as the basis of a new family Limulidae and synonymized it with Polyphemus Lamarck, 1801 (Lamarck's proposed but later unaccepted replacement for Limulus, as discussed by Van der Hoeven, 1838, p. 8) and Xyphotheca Gronovius, 1764 (later changed to Xiphosura Gronovius, 1764, another junior synonym of Limulus). He also included the valid modern genus Tachypleus Leach, 1819 in the family. The primary authority of Leach (1819) is widely recognized in the neontological literature (e.g., Dunlop et al., 2012; Smith et al., 2017). It is also the authority recognized in the World Register of Marine Species (WoRMS Editorial Board, 2021).

Two new amphipod species of the family Bogidiellidae were found in the hyporheal of two small rivers on Corsica. Both new species, Bogidiella (Bogidiella) cyrnensis n. sp. and B. paolii n. sp. (provisionally placed in the subgenus Medigidiella, but a definitive classification will have to wait till males are found), encountered at altitudes of 135 m and 750 m, respectively, show more affinities with certain freshwater species of Sardinia than with marine species of the Mediterranean.

The family Monhysteridae is characterized by 17 valid genera, seven of which are known to be free-living, inhabiting marine sediments. In total, 70 valid marine species are ascribed to these seven genera. Overall, the family is characterized by a confused taxonomic history with a large list of synonyms and species inquirendae. The taxonomic problem is not restricted to the old literature, but inconsistencies also appeared in recent studies. The aim of this study is to show the most important diagnostic characters to identify each genus and provide taxonomic tools for species identification. Dichotomous-keys and illustration-guides are attempted for the marine monhysterid species. For the family and each subfamily, tribe and marine genus a brief historical background, diagnosis and a list of valid species is provided. Hereby, we propose to transfer eight species of the genus Thalassomonhystera to the genus Monhystrella.

Most marine coccoid and sarcinoid green algal species have traditionally been placed within genera dominated by species from freshwater or soil habitats. For example, the genera Chlorocystis and Halochlorococcum contain exclusively marine species; however, their familial and ordinal affinities are unclear. They are characterized by a vegetative cell with lobated or reticulated chloroplast, formation of quadriflagellated zoospores and living epi- or endophytically within benthic macroalgae. They were integrated into the family Chlorochytriaceae which embraces all coccoid green algae with epi- or endophytic life phases. Later, they were excluded from the family of Chlorococcales based on studies of their life histories in culture, and transferred to their newly described order, Chlorocystidales of the Ulvophyceae. Both genera form a “Codiolum”-stage that serves as the unicellular sporophyte in their life cycles. Phylogenetic analyses of SSU and ITS rDNA sequences confirmed that these coccoid taxa belong to the Chlorocystidales, together with the sarcinoid genus Desmochloris. The biflagellated coccoid strains were members of the genus Sykidion, which represented its own order, Sykidiales, among the Ulvophyceae. Considering these results and the usage of the ITS-2/CBC approach revealed three species of Desmochloris, six of Chlorocystis, and three of Sykidion. Three new species and several new combinations were proposed.

Coral reefs in the world occupy around 250.000 km2 of coastal areas and provide habitats for approximately 25 % of marine species.  Reefs are usually reognise as marine rain forest (Knowlton et al., 2010 in Andi Haerul, 2014).  Indonesia has a high level of hard corals diversity, and, at least 80 genera consist of 74 % of 800 coral spesies of the world could be found here.Favia (Oken, 1815) is one genus of Faviidae.  Faviidae is one of the largest coral family, after Acroporidae.  Coral species of Faviidae live in a colony. Generally, the main characteristic of Favia has plocoid shape corallite. Data collection has been conducted on reef flats of Kampung ambong Village in Likupang Timur District of Minahasa Utara Regency. Visual survey method was done at 3 – 5 meters depths during high tide rising. This research was focused on genus Favia (Oken, 1815) of Faviidae family.Five species of hard corals of genus Favia were founded in this study,i.e Favia speciosa (Dana, 1846), Favia favus (Forskål, 1775), Favia truncatus (Veron, 2000), Favia pallida (Dana, 1846) dan Favia matthaii (Vaughan, 1918). These species have similar characteristics in some parts, i.e septum, corallite form and corralite diameter.Keywords: Taxonomy, Hard Coral, Favia (Oken, 1815) ABSTRAK      Terumbu karang di dunia memiliki luas sekitar 250.000 km2 dan merupakan tempat tinggal bagi 25% spesies laut sehingga terumbu karang disebut juga rain forest laut (Knowlton et al. 2010 dalam Andi Haerul, 2014). Indonesia memiliki tingkat keanekaragaman spesies karang yang tinggi yaitu kurang lebih 80 genera meliputi 74% dari 800 spesies yang ada di dunia.Karang Favia (Oken, 1815) merupakan salah satu genus dari famili karang Faviidae yang menjadi salah satu famili terbesar setelah Acroporidae. Spesies dari famili Faviidae hidup secara berkoloni. Ciri-ciri umum dari genus ini adalah bentuk koralit plocoid. Pengambilan data dilakukan di Desa Kampung Ambong Kecamatan Likupang Timur, Minahasa Utara. Metode yang digunakan adalah metode survei jelajah pada kedalaman 3-5 meter pada saat terjadi pasang naik. Karang yang diamati adalah famili Faviidae, genus Favia (Oken, 1815).Pada penelitian ini ditemukan lima spesies karang genus Favia, yaitu Favia speciosa (Dana, 1846), Favia favus (Forskål, 1775), Favia truncatus (Veron, 2000), Favia pallida (Dana, 1846) dan Favia matthaii (Vaughan, 1918). Spesies ini memiliki karakteristik yang hampir mirip pada beberapa bagian seperti septa, bentuk koralit, serta diameter koralit.Kata Kunci: Taksonomi, Karang Batu, Favia (Oken, 1815)

AbstractSome definitions of the term ‘lichen’ have often emphasized the role of the mycobiont as exhabitant in the symbiosis.Mastodia tessellataandTurgidosculum ulvae, both forming lichen-like associations with foliose algae, have traditionally defied that definition. In this study, we delve into the poorly known association ofT. ulvaewithBlidingia minima. Using four molecular markers (nrLSU, nrSSU,RPB1, mtSSU) we show thatT. ulvaeis a member of the familyVerrucariaceae, closely related to the marine speciesVerrucaria ditmarsica. The presence of bitunicate asci and single-cell ascospores is confirmed. Our analysis of a fragment of therbcL marker demonstrates that the photosynthetic partner belongs toB. minima, although relationships within this taxon remain unclear. Transmission electron microscopy allowed us to illustrate howT. ulvaeinteracts withBlidingiacells, and how haustoria in that species differ from those previously investigated in other marine lichen-forming fungi.

Anew species of dinoflagellate cyst, Odontochitina octopus sp.nov., is described from the Upper Cretaceous Kanguk Formation of the Sverdrup Basin, Canadian Arctic Islands. The features that support the proposal of this new species also necessitate the emendation of the genus. Odontochitina octopus is a large, cornucavate, and ceratioid cyst with four finger-like terminations on the apical horns and two terminations on both the postcingular and antapical horns. These finger-like terminations are unique to this new species and are formed by the detachment of the paraplates at mid-length of each horn. All other features of O. octopus conform with the previous description of the genus. In the Family Ceratiaceae four plates form the apical horn, whereas two plates are involved in both the postcingular and antapical horns. In O. octopus the mid-length detachment of the horn-forming paraplates seems to have developed the finger-like terminations. Since the nature and amount of pores and perforations in other species of Odontochitina are variable and possibly linked to changes in the environment, the presence of the multiple-fingered O. octopus in a single widespread horizon might also be indicative of short-lived unusual environmental conditions. At this horizon, which has been dated as late Coniacian by the ammonite Scaphites depressus Reeside, the palynomorph assemblage is highly dominated by marine species.
