Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Abstract The fourth addendum to Schneider and Wynne’s 2007 “A synoptic review of the classification of red algal genera a half century after Kylin’s 1956 ‘Die Gattungen der Rhodophyceen’” is presented, covering the names of genus- and higher-level taxa added or modified since our third addendum (Bot. Mar. 59: 397–404). Since that synopsis, we added 21 new genera in a first addendum, 27 in the second, and 40 in the third, demonstrating the increasing amount of genetic work over more than a decade. In this fourth addendum, we add 58 new genera to the list of red algae as well as many new taxa in the hierarchical framework over the past 3 years. Based upon molecular sequencing, other genera reinstated from synonymy studies are included.

New Genera

In his long career, Maurice Pic (1866–1957), a prolific French entomologist, described many thousands of insect species, subspecies, and varieties, as well as several hundreds, if not more than a thousand, of new genera across orders and families (Villiers 1958a, b). The majority of Pic’s described taxa are beetles, especially in Tenebrionoidea and the former Malacodermata (or Malacodermatidae). Many genera were described in a brief and uninformative style and without explicit family assignment, making it difficult to determine their familial affiliation based on the literature (Pollock 2005). Accordingly, several taxa have remained little known or long-neglected until now. Most of Pic’s type material is deposited in the Muséum national d'Histoire naturelle, Paris (MNHN), where it is possible to examine and provide a possibility to reliably determine their identities.

Insight Into

The aim of this study was to gain further insight into the diversity of Escherichia coli phages followed by enhanced work on taxonomic issues in that field. Therefore, we present the genomic characterization and taxonomic classification of 50 bacteriophages against E. coli isolated from various sources, such as manure or sewage. All phages were examined for their host range on a set of different E. coli strains, originating, e.g., from human diagnostic laboratories or poultry farms. Transmission electron microscopy revealed a diversity of morphotypes (70% Myo-, 22% Sipho-, and 8% Podoviruses), and genome sequencing resulted in genomes sizes from ~44 to ~370 kb. Annotation and comparison with databases showed similarities in particular to T4- and T5-like phages, but also to less-known groups. Though various phages against E. coli are already described in literature and databases, we still isolated phages that showed no or only few similarities to other phages, namely phages Goslar, PTXU04, and KWBSE43-6. Genome-based phylogeny and classification of the newly isolated phages using VICTOR resulted in the proposal of new genera and led to an enhanced taxonomic classification of E. coli phages.

Abstract The Chloropidae is a species-rich family of flies with about 3000 species in four subfamilies. The Chloropinae is the second most species-rich subfamily with almost 1000 described species in 75 accepted genera. There is agreement about the monophyly of the subfamily; however, the relationships among the genera are still poorly understood and some genera are clearly paraphyletic. Thus, the interpretation of the evolution of morphological traits, such as male terminalia sclerites, remains challenging. This is the first phylogenetic study of the Chloropinae using a formal analytical approach, including representatives of 73 genera of the subfamily and 124 morphological characters. The monophyly of the Chloropinae is corroborated. Chloropella is sister to the remainder of the subfamily. Slightly different analytical procedures show stable clades and rogue taxa. We propose a system for the subfamily with ten tribes, three of which are newly proposed here—Chloropellini trib. nov., Chloropini, Chloropsinini trib. nov., Diplotoxini, Eurinini stat. nov., Lasiosinini, Mepachymerini, Meromyzini, Mindini and Pseudothaumatomyini. Eight genera are kept incertae sedis and two new genera are erected. There is compelling evidence that Chlorops and Ectecephalina are paraphyletic.

Upper Paleozoic

In the Lower Devonian the first productellids evolved from their chonetidine ancestors as the Productellinae. This subfamily was the stem group from which all the later Productidina evolved, yet three of its five subfamilies persisted to the end of the Permian. The main characters used in the new classification, here presented, for the Productellidae are described and reviewed, and the main changes seen during its evolution are discussed. Within this new classification five new genera are described: in the Overtoniinae are Barunkhuraya Lazarev from the latest Famennian, Onavia Lazarev from the Tournaisian, both from Mongolia, and Echinariella Lazarev (type species Krotovia jisuensiformis Sarycheva) from the late Permian of Transcaucasia; in the Marginiferinae there is Breileenia Brunton from the Visean of western Europe and in the Plicatiferinae is Maemia Lazarev from the mid and Upper Carboniferous on the coast of the Barents Sea. New species described in these genera are Barunkhuraya indrengynensis Lazarev, Onavia barunkhurensis Lazarev, Breileenia radiata Brunton, Maemia chaykensis Lazarev, and M. nana Lazarev.

Two species are removed from the genus Poa in Australia on the basis of morphology and DNA and placed in new genera. One is placed in Saxipoa Soreng, L.J.Gillespie & S.W.L.Jacobs – type: S. saxicola (R.Br.) Soreng, L.J.Gillespie & S.W.L.Jacobs; and one is placed in Sylvipoa Soreng, L.J.Gillespie & S.W.L.Jacobs – type: S. queenslandica (C.E.Hubb.) Soreng, L.J.Gillespie & S.W.L.Jacobs. An infrageneric classification of Poa is proposed that places all 41 indigenous Australian species in P. subg. Poa supersect. Homalopoa sect. Brizoides. Thirty-three of these species, plus six species of New Zealand Poa, are placed in a new P. subsect. Australopoa Soreng, L.J.Gillespie & S.W.L.Jacobs. Two species are placed in P. subsect. Austrofestuca (Tzvelev) Soreng, L.J.Gillespie & S.W.L.Jacobs, one in P. subsect. Brizoides (Pilg. ex Potztal) Soreng, L.J.Gillespie & S.W.L.Jacobs, and one in P. subsect. Neuropoa (Clayton) Soreng, L.J.Gillespie & S.W.L.Jacobs.

PionosyllisMalmgren, 1867 is revised based on a cladistic analysis of the 41 species considered herein as valid, two newly described species in this paper (Basidiosyllis victoriaeandOpisthodonta russelli), 11 species from other genera actually belonging, or related to,Pionosyllis, and 13 syllid species from different subfamilies. The phylogenetic analysis is based on 55 characters; a strict consensus of 1200 equally parsimonious trees (length = 314 steps) was obtained. The clades containing species usually included withinPionosyllisare newly named within the frame of a new Linnean classification of the group (except for one, belonging to another subfamily). The diagnosis ofPionosyllisis emended, and five new genera are proposed:Synmerosyllis,Basidiosyllis,Westheidesyllis,PerkinsyllisandBrevicirrosyllis.ParaehlersiaSan Martín, 2003, proved to be closely related toPionosyllis. Seven species are transferred toOpisthodontaLangerhans, 1879, here emended, and three transferred toNudisyllisKnox & Cameron, 1970 (according to San Martín & Hutchings, 2006).Opisthodonta uraga(Imajima, 1966) comb. nov. andPerkinsyllis longisetosacomb. nov. are redescribed.Pionosyllis compactaMalmgren, 1867,P. styliferaEhlers, 1913,P. giganteaMoore, 1908,P. enigmatica(Wesenberg-Lund, 1950), andNudisyllis magnidens(Day, 1953) comb. nov., are redescribed.Pionosyllis marquesensisMonro, 1939 andP. proceraHartman, 1965 likely belong to the Syllinae, thus they are not treated in the taxonomic account.
