A new subfamily and species of Ostracoda (Cylindroleberididae,Myodocopa) from the Chatham Rise (New Zealand)

Abstract

The second species of the genus, Macroasteropteron chathamensis sp. nov. is described in the present paper. It was collected from 1000 m depth during the New Zealand national biodiversity programme Ocean Survey 20/20 to the Chatham Rise and the Challenger Plateau. To accommodate this genus, a new subfamily Macroasteropteroninae is described herein. It is defined by the following autapomorphies: locking system on the shell; very small second segment on the second antenna (bearing no dorsal bristles); square shaped third and fourth segments on the same appendage; absence of dorsal bristles on the third segment of the male clasping organ; reverse position of the alpha and beta bristles on the maxillula; almost square shaped skirt on the sixth limb; and a bulbous terminal part of the seventh limb, which, in addition, does not have any bell-bearing bristles. A key to the four subfamilies of Cylindroleberididae is provided.

The leopardChimaera, a new species of chimaeroid fish from New Zealand (Holocephali, Chimaeriformes, Chimaeridae)

A new species ofChimaera is described from three specimens collected from deep water fishing grounds off the North Island of New Zealand at depths ranging from 327–1020 m. This species is distinguished from all other members of the genus by gray coloration with chocolate brown reticulations and spots covering the body and fins, as well as additional external features such as rounded pelvic fins, first dorsal fin with distinct white margin, preopercular and oral lateral line canals sharing a common branch, and morphology of pelvic claspers in males bifid, the distal 1/3 divided, with pale colored fleshy, distal lobes. Comparisons are made toC. monstrosa andC. owstoni, the two most similar species in the genus. this represents the first species ofChimaera to be described from New Zealand.     

The first recent species of the unusual brachiopod Kakanuiella (Thecideidae) from New Zealand deep waters

A new thecideid brachiopod species Kakanuiella chathamensis sp. nov. is described from deep waters on the Chatham Rise, east of South Island, New Zealand. The new species bears an unusual character combination in the shell morphology of its dorsal valve, displaying a mixture of diagnostic characters of both Recent thecideid subfamilies Thecidellininae and Lacazellinae. The resultant consequences for the systematic position of the genus Kakanuiella are discussed.

Systematic revision of the genus Phycodrys (Delesseriaceae,Rhodophyta) from New Zealand,with the descriptions of three new species,P. novae-zelandiae sp. nov., P. franiae sp. nov. and P. adamsiae sp. nov.

Two species of Phycodrys, Phycodrys quercifolia (Bory) Skottsberg and Phycodrys profunda E.Y.Dawson were previously recorded from New Zealand. However, an examination of Phycodrys collections from the New Zealand region showed that all were morphologically different from P. quercifolia (Type locality: the Falkland Islands) and P. profunda (Type locality: CA, USA). RbcL sequence analyses established that the New Zealand Phycodrys species formed a natural assemblage within the genus, consisting of three new species: P. novae-zelandiae sp. nov., P. franiae sp. nov. and P. adamsiae sp. nov. Phycodrys novae-zelandiae is the largest of the three, up to 20 cm in height, with a distinct midrib and multicellular, opposite to subopposite lateral macroscopic veins. It has entirely monostromatic blades except near the midrib and veins, and its procarp contains a three-celled sterile group one (st1) and a one-celled sterile group two (st2). Phycodrys franiae was previously treated as a cryptic species among herbarium collections of P. ‘quercifolia’. It is smaller (4–11 cm high) with weakly developed midribs and veins, the blade is tristromatic throughout, except at the growing margins, and the procarp consists of a four-celled st1 and a two–three-celled st2. Phycodrys adamsiae, previously reported as P. profunda, is a small decumbent or prostrate plant, 1–8 cm long, with a midrib and inconspicuous lateral veins. The blades are tristromatic with serrated margins, two–four-celled surface spines and multicellular marginal holdfasts that differ from those of Californian specimens. The tetrasporangia are borne on marginal bladelets. Phylogenetic analyses place the New Zealand species in a separate group that is distantly removed from most other Phycodrys species.     

New reports and description of a new species of Sabellidae (Annelida) for the Iberian Peninsula and Balearic Archipelago

Sabellidae species from the Iberian Peninsula and Balearic Archipelago waters, including the North-eastern Atlantic Ocean and Cantabrian and westernmost Mediterranean Seas, were studied. The species Amphicorina rovignensis, Dialychone dunerificta, D. usticensis, Euchone cf. limnicola, Euchone cf. pseudolimnicola, Megalomma lanigera, Parasabella tenuicollaris and P. tommasi are recorded for the first time in the area. Bispira primaoculata sp. nov. is a newly described species for the Alborán Sea, characterized by having semicircular branchial lobes, rounded and long dorsal basal flanges, an axial skeleton composed of six longitudinal rows of vacuolated cells, up to three pairs of compound eyes per radiole mainly distributed in the distal half of the crown, appearing at the level of the dorsalmost pair of radioles, and a first chaetiger maximally twice as long as subsequent ones. New information about the habitats of A. rovignensis, D. dunerificta and M. lanigera is also provided.

New species, observations, and a list of new records of brown algae (Phaeophyceae) from the Hawaiian Islands

Two new species of brown algae (Phaeophyceae), Padina moffittiana Abbott et Huisman, sp. nov. and Cutleria irregularis Abbott et Huisman, sp. nov., are described from the Hawaiian Islands (between 19°04′N, 155°35′W and 28°25′N, 178°20′W). In addition, the new combination Cutleria canariensis is proposed for Aglaozonia canariensis. New observations are presented on Nereia intricata Yamada, a species described 67 years ago and known only from its type specimen. New records of a further 14 species are given for the Hawaiian Islands. These 17 taxa bring the total number of species of brown algae recorded for the Hawaiian Islands to 55, an increase of 28%. Of the 15 new records, two are recent ‘accidental’ introductions: Dictyota flabellata (Collins) Setchell et Gardner and Sargassum muticum (Yendo) Fensholt from California. Six records are notable because of their great distances from previously known collections: Nereia intricata Yamada from the Ryukyu Is., Japan; Discosporangium mesarthrocarpum (Meneghini) Hauck, from the Adriatic, Mediterranean, warm Atlantic and southern Australia; Distromium flabellatum Womersley, Spatoglossum macrodontum J. Agardh, and Sporochnus moorei Harvey, from Australia; Desmarestia ligulata (Lightfoot) Lamouroux from temperate and colder waters in the Pacific and Atlantic. A comparison with some Japanese species of Padina confirms that Padina japonica Yamada should be subsumed with Padina sanctae‐crucis Børgesen, as proposed earlier.     

Bracca olafhenkeli sp. nov., a new species of the Ennominae (Lepidoptera: Geometridae) from Sulawesi (Indonesia)

Bracca olafhenkeli sp. nov. is described from the island of Sulawesi, Indonesia, to which it is considered endemic. Morphological characters such as the basic pattern and coloration as well as the genitalia clearly indicate that the species is a typical member of the genus Bracca Hübner, but large, white apical spots on the forewings and extremely broad, white marginal bands on the hindwings render it unmistakable among its congeners. The new species is abundant in montane areas of North, Central and South Sulawesi and seems to be restricted to primary forests. The biology is unknown.     

Alexandrium camurascutulum sp. nov. (Dinophyceae): a new dinoflagellate species from New Zealand

A new species, Alexandrium camurascutulum sp. nov. MacKenzie et Todd, is described from specimens collected from Tasman Bay and the Marlborough Sounds New Zealand. These small (26–28 μm long × 21–24 μm wide) cells can be discriminated from other species in the Alexandrium minutum group by three distinctive morphological features. The sixth pre-cingular plate (6′′) is up to 1.6 times wider than high and the left side of the plate is concave resulting in a markedly ‘hooked’ appearance. In all specimens observed, the first apical plate (1′) does not directly connect with the apical pore plate (Po) and the posterior sulcal plate (S.p.) is markedly different from the usual A. minutum form and may contain a posterior attachment pore (pap) connected to the right side plate margin. The cells may or may not have an anterior attachment pore (aap) in the apical pore plate (Po). The cells display a prominent list along the left sulcal margin and the thecal surface is perforated with numerous areolated pores. A. camurascutulum sp. nov. has been observed occasionally over a number of years in coastal waters of the northern South Island of New Zealand. There is circumstantial evidence that suggests it is not toxic.

A new species of the genus Amolops (Anura: Ranidae) from high-altitude Sichuan,southwestern China,with a discussion on the taxonomic status of Amolops kangtingensis

A new species of the genus Amolops Cope,1865 is described from Xinduqiao,Kangding,Sichuan.It was previously identified as Amolops kangtingensis,which is synonymized to Amolops mantzorum in this study.The new species,Amolops xinduqiao sp.nov.,is distinguished from all other congeners by the following combination of characters:(1) medium body size,adult males SVL 41.2-47.5 mm (n=15,average 43.9 mm),adult females SVL 48.5-56.6 mm (n=15,average 52.5 mm);(2) head length equal to width or slightly wider than long;(3) tympanum small,but distinct;(4) vomerine teeth in two tiny rows,separated by a space about one vomerine teeth row;(5) bony projections on lower jaw absent;(6) dorsolateral folds usually absent;(7) tarsal folds or glands on tarsus absent;(8) circummarginal groove on disc of finger Ⅰ absent;(9) tibiotarsal articulation reaching nostril or beyond;(10) webs of toe Ⅳ reaching to distal articulation,other toes fully webbed to disc;and (11) vocal sac absent in males.     

A new genus and species of heteronemertean from the Changjiang (Yangtze) River Estuary

A new genus and species of heteronemertean, Yinia pratensis gen. nov. and sp. nov., collected from low salinity waters (salinity 0.2–0.4 ‰) at Changjiang River Estuary, is described and illustrated. The species possesses a proboscis with an outer circular and an inner longitudinal muscle layer, and is placed in family Lineidae sensu Gibson. The following combination of morphological features distinguishes the new species from any other genera in this family: proboscis with two muscle crosses; dermis without connective tissue layer between gland cells and body wall outer longitudinal muscle layer; rhynchocoel wall circular muscles not interweaving with adjacent body wall longitudinal muscles; foregut with circular somatic muscles and subepithelial gland cell layer; neurochord cells present in central nervous system; caudal cirrus missing; blood system developed into alimentary plexus extending almost the full length of the body. Another significant character is that the lobular excretory cells are extremely well developed which may represent adaptation to water of low salinity. This revised version was published online in July 2006 with corrections to the Cover Date.
