One New Species

The Daviesia latifolia group, consisting of 16 species from eastern and southern Australia with horizontally flattened, non-pungent phyllodes, more or less united upper calyx-lobes and confluent anther-cells, is revised. Multivariate analysis (ordination and classification) of morphometric data is used to resolve the D. mimosoides/buxifolia species complex. As a result. one new species, D. elliptica, is segregated from D. buxifolia, and a new montane subspecies (acris) is recognised within D. mimosoides. Relationships of all taxa in the D. latifolia group are studied using cladistic analysis. A cline linking D. leptophylla with D. mimosoides through a hybrid zone is described from the Tinderry Mountains near Canberra. Daviesia elliptica, D. laevis, D. mimosoides subsp. acris, D. newbeyi, D. pauciflora and D. suaveolens are described as new, and D. mimosoides var. laifiora is raised to species rank. Twelve natural hybrids are briefly described.* Part I, Aust . Syst . Bot., 1990, 3, 241–51.

During a survey, 12 known and one new species of Ditylenchus Filipjev, 1936 were collected from southern provinces of Iran during 2013–2017. Ditylenchus paraparvus n. sp. is characterised by a short body length (441–543 µm), lateral field with four lines, delicate and short stylet (6–7.5 µm) with small rounded or posteriorly sloping knobs, pyriform and offset basal pharyngeal bulb, V = 67.7–76.4, short post-vulval uterine sac less than one vulval body width long, small spicules (12.5–15 µm) and almost cylindrical tail (71–90 µm) with rounded end. Morphometric data of studied species are presented and intraspecific variation of their morphometrics and morphological characters is discussed. The list of the world Ditylenchus species is updated, and a dichotomous identification key and an updated tabular compendium for 63 valid species is provided.

One New Species

AbstractGenus-group taxon Rhombodineutus Ochs, 1926 is related to Paracyclous Ochs (Indonesia) and Callistodineutus Ochs (Melanesia), classified under Dineutus MacLeay. It occurs in New Guinea and New Britain Island, inhabiting streams and rivers primarily at low and medium altitudes where the species may occur abundantly. Most species live in the forests and have a fairly restricted range, while D. pectoralis Régimbart has passed a niche shift and adapted to exposed and exploited land and spread widely, splitting into a considerable number of races, some of which were found at an elevation of 1500-2000 m. The morphological characters are reviewed and their differentiation examined as a background for the classification of the taxon and a revision of its species which have been placed in three groups, containing 8 species and 11 subspecies. One new species and four new subspecies are described. Keys are provided to the various groups of taxa.

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.

AbstractThe genus Aspidiotes Schönherr, 1847 is revised; 6 species are recognized as valid. Amomphus Schonherr, 1848 is considered to be an unjustified replacement name for Aspidiotes Schönherr, 1847. Phaenognathus Schönherr, 1847 is retained as a subgenus of Aspidiotes although the cladistic analysis failed to find synapomorphies supporting this opinion. One new species, A. (Aspidiotes) gonzalezi, is described from NE Spain (Lerida, Thrragona and Zaragoza). A seventh species currently included in the genus, Amomphus reichei Desbrochers, 1872, is placed incertae sedis; the type specimen has not been traced. Distributional as well as biological data are provided. A cladistic analysis and a biogeographical discussion are provided.

Two New Species

Two new species of Paratrachys, the first known from Australia, are described. P. australia, sp. nov., from coastal New South Wales is placed in the nominate subgenus and P. queenslandia, sp. nov., from Queensland, in P. (Friendiella) Holynski. The species are fully described, illustrated and a brief discussion is presented on the recent generic review by Holynski and the placement of this genus in the familial hierarchy. A modified key for both Paratrachys (Friendiella) and P. (s. str.) the Hederae-circle is presented to incorporate these new species. A cladistic analysis shows that the Paratrachydina is best defined as monotypic.

We review the trans-Andean species of Pimelodus from Colombia, Panamá, and Venezuela. Based on meristic and morphometric data of preserved specimens, four of five species reported from this region are considered valid and two new Colombian species are described. Here we review Pimelodus coprophagus Schultz, 1944 from Lake Maracaibo Basin of Venezuela and Colombia; Pimelodus grosskopfii Steindachner, 1879 from Magdalena River Basin; Pimelodus navarroi Schultz, 1944 from Lake Maracaibo Basin of Venezuela and Colombia; and Pimelodus punctatus (Meek & Hildebrand, 1913) from Atrato, Baudó, and Tuyra River Basins of Colombia and Panamá. Pimelodus crypticus new species is described from the upper Cauca river drainage. Pimelodus yuma new species is described from the Cauca, Magdalena, and Sinú river drainages. A key for species identification and geographical ranges is provided. We also reidentify trans-Andean specimens previously reported as Pimelodus blochii Valenciennes, 1840, a widespread cis-Andean species, or species complex, that ranges across the coastal rivers of the Guianas and Brazil and the Orinoco and Amazon Basins.

One New Species

The genus-level classification of New World Erythroneurini is revised based on results of a phylogenetic analysis of 100 morphological characters. The 704 known species are placed into 18 genera. Erasmoneura Young and Eratoneura Young, previously treated as subgenera of Erythroneura Fitch, and Erythridula Young, most recently treated as a subgenus of Arboridia Zachvatkin, are elevated to generic status. Three species previously included in Erasmoneura are placed in a new genus, Rossmoneura (type species, Erythroneura tecta McAtee). The concept of Erythroneura is thereby narrowed to include only those species previously included in the nominotypical subgenus. New World species previously included in Zygina Fieber are not closely related to the European type species of that genus and are therefore placed in new genera. Neozygina, n. gen., based on type species Erythroneura ceonothana Beamer, includes all species previously included in the “ceonothana group”, and Zyginama, n. gen., based on type species Erythroneura ritana Beamer, includes most species previously included in the “ritana group” of New World Zygina. Five additional new genera are described to include other previously described North American Erythroneurini: Hepzygina, n. gen., based on type species Erythroneura milleri Beamer and also including E. aprica McAtee; Mexigina, n. gen., based on type species Erythroneura oculata McAtee; Nelionidia, n. gen., based on type species N. pueblensis, n. sp., three additional new species, and Erythroneura amicis Ross; Neoimbecilla, n. gen., based on type species Erythroneura kiperi Beamer and one new species; and Illinigina, n. gen., based on type species Erythroneura illinoiensis Gillette. Five new genera, based on previously undescribed species, are also recognized: Aztegina, n. gen, based on A. punctinota, n. sp., from Mexico; Amazygina, n. gen., based on type species A. decaspina, n. sp., and three additional new species from Ecuador; Hamagina, n. gen., based on type species H. spinigera, n. sp., and two additional new species from Peru and Ecuador; Napogina, n. gen., based on type species N. recta, n. sp., and one additional new species from Ecuador; Perugina, n. gen., based on type species P. denticula, n. sp., from Peru; and Spinigina, n. gen., based on type species S. hirsuta, n. sp., and an additional new species from Peru. Phylogenetic analysis suggests that the New World Erythroneurini consist of three lineages resulting from separate invasions from the Old World.

Abstract Two known and one new species of Paraphanolaimus are described, viz. P. behningi from Germany, P. anisitsi from Paraguay and Germany and P. paraguayensis sp. n. from Paraguay. Paraphanolaimus paraguayensis sp. n. is characterised by 0.84-0.94 mm long body, presence of 37-44 lateral epidermal glands, strongly sclerotised and broad cylindrical stoma, swollen tail tip; female reproductive system with developed spermathecae, straight vagina; male without neck setae, 16-19 tubular supplements, two precloacal and nine to ten caudal setae, spicules 32-33 μm long, arcuate, with oval manubrium and fusiform shaft, platelike gubernaculum. Paraphanolaimus indicus and P.micoletzkyi are considered as species inquirendae. An emended diagnosis and a revised classification of Paraphanolaimus are proposed and a key to the species of the genus is provided. Aphanonchus bayensis (Keppner, 1988) comb. n. is proposed for Paraphanolaimus bayensis Keppner, 1988.

Eusocial Species

Sampling of eight sites along the west coast of Barbados, West Indies, yielded 14 species of sponge-dwelling shrimps in the gambarelloides group of the genus Synalpheus, including one new species described here as Synalpheus microneptunus n. sp. The new species is a member of the S. paraneptunus Coutière species complex and is distinguished from other species in that group by the combination of four carpal segments in the second pereopod, uropodal exopod with 2 nd distolateral tooth smaller than the other two teeth and set in line with movable spine, and a small blade on the scaphocerite. Synalpheus microneptunus n. sp. is the smallest species in the complex (2.2-2.9 mm CL) and lives in small colonies, usually with fewer than 10 individuals, often with a single breeding female. Synalpheus thele Macdonald, Hultgren & Duffy is reported for the first time from outside its type locality in Jamaica. Sampling in Barbados produced fewer species than did similar efforts in Jamaica and Curaçao, possibly due to the relatively isolated position of the island at the eastern (windward) edge of the Caribbean Sea.
