The systematics of the Family Carditidae is currently poorly elucidated. This paper reviews the Eocene to Pleistocene carditids from Patagonia and Entre Ríos Province (Argentina). Twelve species are described and illustrated and the presence of the genera Cyclocardia Conrad, Pleuromeris Conrad, Scalaricardita Sacco, Fasciculicardia Maxwell and Purpurocardia Maxwell in southern South America is discussed. The genus Scalaricardita is documented for the first time in South America. Two new genera, Darwinicardia gen. nov. and Kolmeris n. gen. are proposed for the species ‘Venericardia’ patagonica (Sowerby) and ‘V.’ tehuelchana (Ihering), respectively, and one new species, Cyclocardia dalek sp. nov., is described.

AbstractSome 35 species (mostly Neotropical, 22 new) of acalypterate flies representing 17 genera (3 new) in six families, as follows, are treated: Family Cypselosomatidae. One species from Nepal, Cypselosoma gephyrae Hendel (?), is discussed.Family Pseudopomyzidae. The classification of the family is reviewed, and a key to the world genera is provided. The genus Latheticomyia Wheeler is placed here for the first time, and two new species, L. longiterebra (Peru) and L. rotundicornis (Mexico), are described. Two new genera, Pseudopomyzella and Rhinopomyzella, are erected for three new species, P. flava (Peru), R. albimana (Brazil), and R. nigrimana (Brazil).Family Periscelidae. The genus Periscelis Loew is recorded from Mexico and Peru. Neoscutops peruvianus and Scutops striatus, both from Peru, are described as new.Family Aulacigastridae. The classification of the family is reviewed and a key to the world genera is provided. Schizochroa plesiomorphica (Peru), S. minuta (Ecuador), S. ecuadoriensis (Ecuador), Cyamops neotropicus (Peru), C. australicus (Queensland), and Planinasus venezuelensis (Venezuela) are described as new.Family Odiniidae. The classification of the family is reviewed and a key to the subfamilies and the world genera is provided. Two new species of Schildomyia Malloch, S. peruviana (Peru) and S. trinidadensis, are described. A new genus, Shewellia, is erected for the species S. agromyzina (Peru).Family Heleomyzidae. One new species of Cephodapedon Malloch, C. nigriventer (Chile), is described. The genera Mayomyia Malloch and Cinderella Steyskal are reviewed and placed in this family for the first time.

Guţu (2016) described a new subfamily, seven new genera and 21 new species in the family Leptocheliidae. However, another five genera and twelve new species, not mentioned by him, were described in 2015 and 2016. Study of the overlooked genera reveals that the morphology of the female of Permixtimella (genus described from both sexes) is similar to those of the type-female of the genus Ektraleptochelia (whose male is unknown). Permixtimella is considered a junior synonym of Ektraleptochelia, which includes two species: E. phoxops and E. oculifurcillata. The place of Ektraleptochelia, Catenarius and Larsmentia within leptocheliid systematics, formerly in the subfamily Catenariinae, is reconsidered and the last genus retained. Some similarities between the females of Nuberis and Bathyleptochelia are presented for the first time. The species Leptochelia acrolophus, L. mexicana, L. ortizi, L. taitungensis and L. grandidentata are transferred to other genera, becoming Chondrochelia acrolophus, C. mexicana, C. ortizi, C. taitungensis and Makassaritanais grandidentatus, respectively. The species Leptochelia pinarensis and L. suhi are considered a junior synonym of Leptochelia forresti and Makassaritanais grandidentatus, respectively.

Echinoderms of the Middle Ordovician Platteville and lower Galena Groups of north-central Illinois and south-central Wisconsin are represented by at least seven classes including the Homoiostelea, Cystoidea, Crinoidea, Stelleroidea, Edrioasteroidea, Cyclocystoidea, Echinoidea, and possibly Holothuroidea. The most abundant and diverse echinoderms are monocyclic and dicyclic inadunate and camerate crinoids, of which the cupulocrinids and glyptocrinids are best represented. Thirteen new species and one new genus of crinoids are described:Cremacrinus guttenbergensis, Anulocrinus forrestonensis, Isotomocrinus minutus, Carabocrinus oogyi, Dendrocrinus? springeri, Merocrinus britonensis, Cupulocrinus plattevillensis, C. molanderi, Reteocrinus rocktonensis, R. spinosus, Traskocrinus mahlburgi(n. gen. et sp.),Rhaphanocrinus buckleyi, Glyptocrinus charltoni, andG. pustulosis.One new species of rhombiferan cystoid,Coronocystis durandensis, is also described. Echinoids of the family Bothriocidaridae (Bothriocidaris solemin. sp. andNeobothriocidaris templetonin. sp.) are reported for the first time from North America and appear to be the earliest recorded occurrence. Remains of a third bothriocidarid characterized by coalesced podial pores have also been discovered. Light and scanning electron microscopy of well preserved cyclocystoid specimens reveal a number of previously undescribed morphologic features of the central disc and submarginal ring that may shed some light on their functional morphology.Cupulocrinus gracilisRamsbottom from the Upper Drummuck Group Starfish Bed at Thraive Glen near Girvan, Scotland, is here reassigned toC. drummuckensisn. sp.Echinoderms are associated with an abundant and diverse fauna consisting largely of suspension feeders, primarily strophomenid and orthid brachiopods and trepostome and cryptostome bryozoans. Other common groups include corals, trilobites, sponges, and mollusks. Filamentous brown, foliose red and siphonaceous green algae are associated with the fauna at some localities.Carbonate rocks of both the limestone and dolostone facies of the Platteville (Briton, Walgreen and Forreston Members) and lower Galene Groups in the study area consist primarily of abundant shelly invertebrates occurring as whole and broken, unabraded, commonly articulated remains “floating” in a calcisiltite matrix that is highly bioturbated. Carbonate sediments appear to have been deposited in a near-to below wave base, highly stable, open marine environment characterized by low depositional slopes, good circulation and low terrigenous influx.

Eight new species of carnivorous sponges are described from southern South America, off Diego Ramírez Archipelago (south Chile): Abyssocladia diegoramirezensis, sp. nov., A. umbellata, sp. nov., Asbestopluma (Asbestopluma) bitrichela, sp. nov., A. (A.) magnifica, sp. nov., A. (A.) microstrongyla, sp. nov., A. (Helophloeina) delicata, sp. nov., Chondrocladia (Chondrocladia) schlatteri, sp. nov. and C. (Meliiderma) latrunculioides, sp. nov. Most of these sponges were sampled from an antipatharian coral collected accidentaly by demersal fisheries, which indicates an unexpected high diversity and abundance of carnivorous sponges in this area. The taxonomy and biogeography of the family Cladorhizidae is discussed, with an emphasis on cladorhizid versus phellodermid affinities of Abyssocladia, and on the possibility that species bearing either cleistochelae or arcuate chelae as the sole chelae morphotype may belong in this genus. A synthesis of the geographic as well as bathymetric distribution of cladorhizids is presented.

Two new genera and five new species of Selachinematidae are described from the New Zealand upper continental slope (350-1240 m depth). Synonchiella rotundicauda sp. nov. is characterised by cephalic setae 0.25 cbd long, mandibles each with two pairs of hooks and two wing-like projections laterally, eight cup-shaped pre-cloacal supplements and short rounded tail. Pseudocheironchus gen. nov. is similar to Cheironchus, but differs from the latter in having a cuticle without lateral differentiation, cephalic setae only slightly longer than the outer labial sensillae, and a posterior buccal cavity with three equal mandibles. Pseudocheironchus ingluviosus gen. et sp. nov. is characterised by mandibles with eight blunt teeth, multispiral amphideal fovea with five turns, and a short rounded tail. Males of this new species with 17-19 cup-shaped pre-cloacal supplements. Males of the genus Cobbionema are described for the first time; C. trigamma sp. nov. is characterised by four long cephalic setae and six smaller outer labial setae in one circle, six rhabdions surrounding the anterior buccal cavity, each with two pairs of pointed projections at their posterior extremities, posterior buccal cavity widening posteriorly, with three pairs of rhabdions fused posteriorly and widening anteriorly, males with two testes pointing anteriorly and with reflexed posterior testis, and no pre-cloacal supplements. Gammanema agglutinans sp. nov. is characterised by a short, stout body often covered in adhering mucus and detritus, cuticle with minute spines, leaf-shaped somatic setae with ducts, sexual dimorphism in the shape of the amphideal fovea (loop-shaped in males and spiral in females), posterior buccal cavity with three pairs of broad, column-shaped rhabdions fused anteriorly, intestine cells with orange-brown granules, and small tubular pre-cloacal supplements. Bendiella gen. nov. is most similar to Halichoanolaimus, but differs from the latter, and all other genera of the family Selachinematidae, in having a cuticle with lateral differentiation consisting of longitudinal rows of larger dots, and from all other genera of the Choniolaiminae in lacking pre-cloacal supplements. Bendiella thalassa gen. et sp. nov. is characterised by amphideal fovea with 5.25 turns, anterior buccal cavity with twelve rhabdions, each with a pair of pointed projections at posterior extremity, posterior buccal cavity with three Y-shaped pairs of slender rhabdions fused from two thirds of distance from anterior ends, and conico-cylindrical tail.
