A parsimony analysis of recently collected species sharing several features such as scalpellate acrostichals, often setae apically on the wing membrane and often strongly extended costa, together with 38 genera show that the collected species can be assigned to Antillocladius S ther, 1981, Compterosmittia S ther, 1981, and one new genus, Litocladius. Nine new species of Antillocladius are described and figured as male imagines: A. calakmulensis, A. herradurus and A. zempoalensis from Mexico; A. venequatoriensis from Ecuador and Venezuela; A. ubatuba from Brazil and Venezuela; and A. biota, A. folius, A. musci, and A. sooretama from Brazil. The female of A. musci, the pupae of A. antecalvus S ther, A. folius, and A. musci, and the larvae of A. folius and A. musci are also described and figured. New records of A. antecalvus S ther from Brazil and Venezuela; of A. arcuatus S ther from Brazil, Mexico and Venezuela; A. pluspilalus S ther from Ecuador and Mexico and of A. zhengi Wang and S ther from Thailand are given. The genus Antillocladius S ther, 1981, originally described from the British West Indies, now includes 15 species from North, Central and South America, Russia, China and Thailand. Keys to all known males, females, pupae and larvae are given. Four new species of Compterosmittia are described and figured as male imagines: C. aberrans from Costa Rica; C. croizati from Brazil and Venezuela; C. pittieri from Venezuela; and C. berui from Brazil. The genus Compterosmittia S ther, 1981, originally described from the British West Indies, now includes 8 to 10 species from North, Central and South America, Australia, Oceania and Southeast Asia. A key to male imagines is given. The new genus, Litocladius, includes a single species, L. mateusi, described as male, female and pupa. The immatures of all three genera are terrestrial or associated with phytotelmata, and notes on their biology and larval habitats are included.

Sæther (1981) erected the genus Diplosmittia based on a species from Saint Lucia and Saint Vincent in the British West Indies. The genus was revised by Pinho et al. (2009). To date, the genus comprises ten species: Diplosmittia harrisoni Sæther, 1981; D. carinata Sæther, 1985; D. recisus Sæther, 1988; D. beluina Andersen, 1996; D. forficata Andersen, 1996; D. plaumanni Pinho, Mendes & Andersen, 2009; D. boraceia Pinho, Mendes & Andersen, 2009; D. aragua Pinho, Mendes & Andersen, 2009; D. cerayma Pinho, Mendes & Andersen, 2009; and D. caribensis Wiedenbrug & Silva, 2016. Diplosmittia sasai Makarchenko & Makarchenko, 2005 was placed as a synonym of Pseudosmittia mathildae Albu, 1968 by Makarchenko & Makarchenko (2008). Except for D. carinata from Michigan, U.S.A., all species are Neotropical and mostly recorded from the Caribbean and northern part of South America. During field work in a remote mountainous region in the Brazilian Amazon, a unique new species with the gonostylus split into three parts was collected and is described and figured below. In addition, new records of D. plaumanni are provided.

Two New Species

The present paper contains descriptions of two new species and one new genus: Latinopsis patagonica gen. nov., sp. nov., and Candona quasiincarum sp. nov. Both species were collected during a two-month Franco-Chilean expedition to Madre de Dios archipelago in January and February 2006. The following new systematic arrangements are proposed: L. anisitsi (Daday, 1905) comb. nov., L. columbiensis (Mehes, 1914) comb. nov., and L. falclandica (Vavra, 1898) comb. nov. Latinopsis anisitsi is redescribed from the type material and a lectotype is designated. Two species are excluded from the subfamily Candoninae, one of which is Danielocandona albida (Sars, 1901). After examination of the type material the species is reclassified as Neocypridopsis albida (Sars, 1901) comb. nov. A checklist of the known species of Candoninae of South America and the West Indies is provided.

Currently, 24 species are known for the spider genus Enna O. Pickard-Cambridge, from North, Central and South America, of which six are known from Brazil. In this study four new species are described and illustrated based on female specimens from the Southeastern and Southern Brazilian states of Minas Gerais, São Paulo, Rio de Janeiro and Paraná. Enna trivittata sp. n., E. segredo sp. n., E. meridionalis sp. n. and E. caparao sp. n. can be distinguished from all known species by the general shape of the epigynum. New records in Brazil are presented for E. braslandia Silva, Lise & Carico and E. redundans (Platnick).

Bitentaculate Cirratulidae (Annelida, Polychaeta) collected chiefly during cruises of the R/V Anton Bruun, USNS Eltanin, USCG Glacier, R/V Hero, RVIB Nathaniel B. Palmer, and R/V Polarstern from the Southern Ocean, Antarctica, and off Western South America

Antarctic Species

Forty-one species in five genera of bitentaculate cirratulids are reported from new collections from South America, the Southern Ocean, and seas around Antarctica. Twenty-seven species are new to science; one new genus is described to deal with some species formerly identified as Chaetozone. New records, synonymies, and new combinations are reported. Previous records are reviewed with type specimens of most species reexamined and redescribed. The sub-Antarctic species Aphelochaeta cincinnata (Ehlers, 1908) does not occur in Antarctica: the numerous published records of this species instead belong to several new species. The types of Tharyx epitocus Monro, 1930, and Tharyx fusiformis Monro, 1939, have spines in posterior setigers and are referred to other genera. Among the 41 species treated in this study, 11 belong to Aphelochaeta, eight are new; eight species belong to Caulleriella, six are new; six species belong to Chaetocirratulus n. gen., three are new; 12 species belong to Chaetozone, seven are new; and four species belong to Tharyx, three are new. Numerous samples come from slope and abyssal depths, expanding our knowledge of the distribution of Southern hemisphere deep-sea cirratulids.

Three New Species

Elmidae is one of the most diverse families of aquatic beetles, with more than 1500 species in 151 genera. The Neotropical genus Portelmis formerly comprised five species known from Central and northern South America, divided into two species groups. Three new Brazilian species from the nevermanni group are described and illustrated here: Portelmis vanini sp. nov., Portelmis krolowi sp. nov. and Portelmis fusariae sp. nov. New species records for the North, Central-West and Southeast of Brazil are presented. We also provide first SEM images and an updated key for Portelmis species.

First Time

The family Anthomyzidae (Diptera: Acalyptrata) is recorded from China for the first time based on 11 species, 6 of them new to science. A distinctive new genus Marshallya gen. nov. is described, based on single peculiar species, M. platythorax sp. nov. (both sexes) from Sichuan. Other new species, viz. Amygdalops sevciki sp. nov. (Hainan I.) (both sexes), Epischnomyia tkoci sp. nov. (Sichuan) (male only), Anthomyza ornata sp. nov. (Sichuan) (female only), Anthomyza sulphurea sp. nov. (Yunnan) (both sexes) and Arganthomyza hyperseta sp. nov. (Shaanxi) (male only) are described and illustrated in detail. Male-female association of two Amygdalops species is clarified by means of molecular barcoding and the female of A. bisinus Roháček, 2008 is correctly identifi ed and described. Relationships of all these taxa are discussed. Five species, viz. Amygdalops bisinus (Hainan I.), Epischnomyia merzi Roháček, 2009, Anthomyza cuneata Roháček, 1987, Anthomyza trifurca Sueyoshi & Roháček, 2003 (all from Sichuan) and Arganthomyza versitheca Roháček, 2009 (Shaanxi, Sichuan) are new additions to the Chinese fauna of Anthomyzidae. DNA sequences of the barcoding region of COI have been obtained for 3 species, Amygdalops bisinus, Amygdalops sevciki and Marshallya platythorax. Biology and distribution of all 11 species are discussed. First photographs of living Anthomyzidae from East Asia are presented. Based on knowledge of Anthomyzidae from neighbouring areas the diversity of the Chinese fauna of the family is estimated to include 50-60 species.

Branchiura Sowerbyi

The genus Monopylephorus Levinsen, 1884 is revised, and divided into three genera. Monopylephorus includes rubroniveus, limosus, kermadecensis, parvus, irroratus, aucklandicus, and the new species cuticulatus and evertus. Rhizodrilus Smith, 1900 includes lacteus, africanus, pacificus, lowryi, and arthingtonae, the last two being transferred from Torodrilus Cook, 1970 and Rhyacodrilus Bretscher, 1901 respectively. Peristodrilus gen.nov. contains the single species montanus. Two other species (M. longisetosus and M. frigidus) will be referred to a new genus within the Phallodrilinae rather than the Rhyacodrilinae. The single member of the Branchiurinae, Branchiura sowerbyi Beddard, 1892 is related to both Rhizodrilus and Bothrioneurum Stolc, 1888 and is included with the Rhyacodrilinae. Telmatodrilus multiprostatus does not usually have its spermathecae in IX but in X as normal, and is not related to Rhizodrilus.The diffuse prostates in some Rhyacodrilinae may have groups of cells penetrating the muscle layers of the atria, somewhat resembling the clustered cells of the Telmatodrilinae, but with the cell bodies still forming a continuous atrial covering.The forward relocation of the spermathecae in Rhizodrilus and their absence in Bothrioneurum seems to be related to the development of large copulatory bursae in XI and the occupation of much of X by atria and vasa deferentia.
