Distinguishing Features

The Australian species of Leiognathidae are revised and their distinguishing features more clearly defined. Fifteen Australian species are recognized: Gazza minuta, Leiognathus aureus, L. bindus, L. blochii, L. decorus, L. elongatus, L. equulus, L. fasciatus, L. leuciscus, L. smithursti, L. splendens, Leiognathus sp., Secutor insidiator and S. ruconius. Diagnostic characters for the species are difficult to ascertain as the family tends to be meristically constant. Identification relies principally on a combination of body proportions, distribution of scales, tooth shape and arrangement, and body pigmentation patterns. Species descriptions, figures, abbreviated synonymies and geographic distributions within Australia are presented for all species, and an identification key is given. Incorrect usage in the literature of several species names, including L. elongatus, L. brevirostris and L. lineolatus, is discussed.

A reconsideration of the diagnostic characters of Atya Leach and Atyoida Randall supports their generic separation. Accordingly, Atyoida is reinstated as a full genus of which the distinguishing features are slender third peraeopods with a relatively short merus, a tapering endopod in the male first pleopod and protandry. It includes three species, A. bisulcata Randall from the Hawaiian Islands, A. pilipes (Newport) widespread in the Indo-Pacific area, and A. striolata (McCulloch & McNeill) found only in Australia. A. striolata is fully redescribed. Morphological variation throughout its range is slight; no subspecies are distinguishable. It is suggested that larvae hatch in estuaries and that protandry is an adaptive life-cycle strategy.

Natural Groups

The family Pangasiidae belongs to the suborder Siluroidei, order Siluriformes, and suborder Ostariophysi. Since the groups were established as Pangasiini Bleeker, 1858; its content and classification have been greatly changed. Judging from the literature, the main constraint to cultivate wild species and to optimize the production of cultured species is needed to the poorly documented systematics of this family. Therefore the objective of the present study is to provide the diagnostic characters and the keys for identification the genera of Pangasiidae. The results clearly demonstrate that biometrically four natural groups can be distinguished. They are the genus Helicophagus, Pangasianodon, Pteropangasius, and Pangasius. The diagnosis of the family, the identification key of the genera and the description are given.

Species Descriptions

The family Sphaerolaimidae Filipjev, 1918 includes nematodes that are characterized by the finely striated cuticle, round amphids, broad buccal cavity with longitudinal ribs, and single anterior ovary in females. Parasphaerolaimus species from this family are found in intertidal and subtidal sediments and have also been reported from mangroves and estuaries. Parasphaerolaimus pilosus sp. n. is characterized by the moderately plump body, presence of lateral alae, long cervical setae, small amphids in males, and relatively short spicules. As a result of a comprehensive evaluation of species descriptions, eight species in the genus Parasphaerolaimus are recognized valid, and an identification key to species level is provided.

Pseudothilmanus Pic, 1918 is redescribed and two species, P. alatus Pic, 1918 and P. marginatus Pic, 1918, are placed in the genus. The subgenus Drilothilmanus Pic, 1918 is synonymized with the nominotypical genus on the basis of low morphological divergence and redundancy in classification. Pseudothilmanus is newly classified in the family Rhagophthalmidae, in contrast to the original placement in Drilidae. Diagnostic characters for Pseudothilmanus and both species placed within the genus are illustrated.

AbstractThree new species of Tabanidae egg parasitoids are described: Telenomus hybomitraesp. nov. and Telenomus utilissp. nov., both reared from eggs of Hybomitra nitidifrons nuda (McDunnough) and Hybomitra lasiophthalma Macquart, and Telenomus chrysopsissp. nov., reared from eggs of Chrysops aestuans Wulp, Chrysops excitans Walker, and Chrysops mitis Osten Sacken. Specimens of these species were compared with type specimens of known New World species of scelionid parasitoids attacking tabanid eggs. Diagnostic characters and identification key to the Nearctic species are provided.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).

A new species, Stigmocheylus persicus sp. nov. (Trombidiformes: Prostigmata: Stigmocheylidae) is described based on adult females from Noor, Mazandaran province, northern Iran. The new species can be distinguished from other species by the following features: non-segmented peritremes; absence of setae c3; presence of setae g2; coxa II with four setae; genu I with nine setae; tarsi I–IV with 24(+2ω)–11(+1ω)-11-10 setae. This finding presents the first new species of the family Stigmocheylidae Berlese, 1910 from Asia. Additionally, an identification key to known species of Stigmocheylus is updated.

A New Species

A new amphipod species of the genus Elasmopus Costa, 1853 is described based on material collected from intertidal rocky shore, near the Suape Harbor, coast of the Brazilian state of Pernambuco. The new species may be recognized by the propodus of gnathopod 2 suboval, slightly tapering distally, palmar margin not defined by a stout seta, spine, or palmar corner, with a subdistal blunt tubercle, posterior margin covered by a dense fringe of plumose setae, and posterior margin of basis of pereopod 7 castelloserrate. This is the ninety-fifth species of the genus Elasmopus described worldwide, the most diverse genus in the family Maeridae Krapp-Schickel, 2008, and the eighth species recorded from Brazilian waters. An identification key to Brazilian species of Elasmopusis also provided.
