Ovarian structure in a millipede,Eumastigonus sp. (Diplopoda; Cambalidae), from New Zealand

Abstract

The ovaries of Eumastigonus sp. (Diplopoda; Cambalidae) are arranged in irregularly shaped clusters of oocytes at different stages of development. These are attached to the germarium, and in close proximity to the digestive tract (both mid‐gut and hindgut), or embedded in a liver‐like tissue. Five sizes of oocytes could be distinguished, which represent five different generations of oocytes. This millipede species appears therefore to be iteroparous, capable of reproducing at least five times.     

Revision of the genus Helastia sensu stricto with description of a new genus (Lepidoptera: Geometridae: Larentiinae)

Abstract

Helastia Guenée, 1868 is redefined and redescribed. New Zealand species previously placed in that genus but not congeneric with the type species are reassigned to either the available genera Epyaxa Meyrick, 1883, Asaphodes Meyrick, 1885 and Xanthorhoe Hübner, [1825] or placed in a newly described genus, Gingidiobora. Six Australian species placed in Xanthorhoe are shown to be congeneric with three New Zealand species, previously placed in Helastia and here transferred to Epyaxa.

Eight new species are described in Helastia: Helastia alba n. sp.; H. angusta n. sp.; H. christinae n. sp.; H. cryptica n. sp.; H. mutabilis n. sp.; H. ohauensis n. sp.; H. salmoni n. sp.; H. scissa n. sp. The following new combinations and synonymies are proposed: Asaphodes chlorocapna (Meyrick, 1925) n. comb.; A. citroena (Clark, 1934) n. comb.; A. glaciata (Hudson, 1925) n. comb.; A. ida (Clark, 1926) n. comb; Epyaxa agelasta (Turner, 1904) n. comb.; E. centroneura (Meyrick, 1890) n. comb.;

E. epia (Turner, 1922) n. comb.; E. hyperythra (Lower, 1892) n. comb.; E. lucidata (Walker, 1862) n. comb.; E. sodaliata (Walker, 1862) n. comb.; E. subidaria (Guenée, 1857) n. comb.; E. venipunctata (Walker, 1863) n. comb.; Gingidiobora nebulosa (Philpott, 1917) n. comb.; G. subobscurata (Walker, 1862) n. comb.; Helastia clandestina (Philpott, 1921) n. comb.; H. corcularia (Guenée, 1868) n. comb. (= Larentia infantaria Guenée, 1868 n. syn.); H. expolita (Philpott, 1917) n. comb.; H. siris (Hawthorne, 1897) n. comb.; H. triphragma (Meyrick, 1883) n. comb.     

Revision of the Acanthoclinidae (Pisces: Perciformes), with descriptions of a new genus and five new species

Abstract

The family Acanthoclinidae includes 10 species: Acanthoclinus fuscus Jenyns, 1842; Taumakoides littoreus ((Forster) Bloch & Schneider, 1801); T. rua n. sp.; T. marilynae n. sp.; T. matti n. sp.; Belonepterygion fasciolatum (Ogilby, 1889); Beliops xanthokrossos n. gen. et sp.; Acanthoplesiops indicus (Day, 1888); A. hiatti Schultz, 1953; and A. psilogaster n. sp. Acanthoclinus quadridactylus (Bloch & Schneider, 1801) and A. trilineatus Griffin, 1933, are reduced to synonymy under Taumakoides littoreus ((Forster) Bloch & Schneider, 1801).

Osteological and morpological character states, between and within genera, suggest that Acanthoclinus and Taumakoides are close to the stock from which the family is derived. There is also compelling evidence that T. matti is the least specialised species of Taumakoides. Progressive specialisation is evident in the remaining genera, with Acanthoplesiops being the most highly specialised.

The family occurs primarily in shallow waters of the Indian and western Pacific oceans; most of the species are found about New Zealand. The centre of origin of the Acanthoclinidae was probably on the Indian-Australian Plate (which includes the New Zealand continental shelf). Acanthoplesiops hiatti and A. indicus are considered to be endemics of the Pacific and African plates, respectively.

A key to species is included.

Revision of Sigaloeista Shea & Griffiths, 2010 (Helicarionidae: Gastropoda: Stylommatophora) from eastern Australia

ABSTRACT

Sigaloeista Shea & Griffiths, 2010 is a genus of small, litter-dwelling helicarionid snails that occurs in the rainforest and wet sclerophyll forest of northeastern New South Wales and southern Queensland. This group currently comprises three species known only from their shell morphology. We revise the taxonomy of this group using a comparison of key morphological features and mitochondrial genes COI and 16S, and describe four new species: Sigaloeista gracilis n. sp.; S. cavanbah n. sp.; S. dorrigo n. sp.; and S. ramula n. sp. Sigaloeista is unified by shared morphological characters including a small, glossy, discoidal shell of about 4.5 whorls, a body with a pronounced caudal horn and large, leaf-shaped shell lappets, and a reproductive system with a short vagina, absent epiphallic caecum, flagellum with internal cryptae and spermatophore with accessory spines.

Larvae designated as type specimens of H. angularis are shown to be Apteryoperla monticola Wisely.     

Typhlocybinae of New Zealand (Homoptera: Cicadellidae)

Two tribes of the subfamily Typhlocybinae are represented in New Zealand, as follows. Erythroneurini: the cosmopolitan genus Zygina is represented by 4 endemic species—toetoe, ramsayi n.sp., dumbletoni, and agni n.sp.—plus zealandica, which occurs in Australia also. Typhlocybini: Typhlocyba froggatti, T. lethierryi, Ribautiana tenerrima, Eupteryx melissae, Kybos smaragdula, and K. betulicola are introduced Northern Hemisphere elements; Matatua montivaga n.gen.&sp. is endemic; M. maorica (formerly Dikraneura maorica), also endemic, is of uncertain identity in the absence of male specimens. Keys are given for the separation of all taxa, the genera and species are described, and all species except Matatua maorica are figured.     

Holotrich Ciliates from the Stomach of Hippopotamus amphibius, with Descriptions of Two New Genera and Four New Species

SYNOPSIS. Holotrich ciliates from the stomach contents of Hippopotamus amphibius are described, including details of their infraciliature. They are placed in 4 families: subclass Holotrichia, order Gymnostomatida, suborder Rhabdophorina, family Buetschliidae: Blepharozoum binucleatum n.sp., Cucurbella vivax n.g., n.sp.; order Trichostomatida, family Plagiopylidae: Paraplagiopyla kiboko n.g., n.sp.; family Paraisotrichidae: Paraisotricha minuta Hsiung, 1930; family Blepharocorythidae: Charonina hippopotami n.sp. Paraisotricha minuta appears identical to the form found in the cecum and colon of the horse; Blepharozoum binucleatum, Cucurbella vivax and Charonina hippopotami also approach species found in the digestive tract of Equidae. By contrast, Paraplagiopyla kiboko resembles species that are free-living or are commensal in the digestive tract of Echinodermata.     

Revision of the fishes of the New Zealand genus Hemerocoetes (Perciformes: Percophididae), with descriptions of two new species

Abstract

Five species of the marine New Zealand genus Hemerocoetes are recognised and described: H. monopterygius (Schneider) [= H. acanthorhynchus (Forster)]; H. morelandi n.sp.; H. pauciradiatus Regan; H. artus n.sp.; and H. macrophthalmus Regan. H. waitei Regan is placed in synonymy with H. macrophthalmus. H. morelandi differs from the two other species possessing a relatively wide interorbital and small eye in lacking a dorsal iris flap and (mature males) in having an elongate first dorsal fin ray. It differs from H. monopterygius in having an elongate barbel at the tip of the upper jaw in mature males, and from most specimens of H. pauciradiatus in having 36–38 anal fin rays. H. morelandi is known primarily from off the Auckland Islands and Campbell Island, whereas H. monopterygius is widespread around the North and South Islands and the Chatham Islands, and H. pauciradiatus is commonest off the southern portion of the South Island and off the Chatham Islands. H. artus differs most noticeably from the similar H. macrophthalmus in having unbranched dorsal fin rays. Both have relatively narrower interorbitals and larger eyes and occur in deeper water than the other three species, but H. artus is known from south of latitude 44.0°S, whereas H. macrophthalmus is known primarily from north of about 44.5°S. In possessing a continuous dorsal fin lacking spines, Hemerocoetes is the most distinctive of the percophidid genera. It most closely resembles the western Australian Branchiopsaron ozawai and the Japanese Spinapsaron barbatus.     

New genera and species of Leptophlebiidae (Ephemeroptera) from New Zealand

Abstract

New genera Isothraulus, Arachnocolus, and Penniketellus are established for three species of leptophlebiid mayfly from New Zealand. Each genus is monotypic and endemic to New Zealand. Isothraulus and Arachnocolus are known only from the northern North Island, and Penniketellus is known only from the Arthur's Pass area of the central South Island. The male and female imago, nymph, and egg of Isothraulus abditus n.sp., the male imago, male subimago, and nymph of Arachnocolus phillipsi n.sp., and the male and female imago, female subimago, and egg of Penniketellus insolitus n.sp. are described. The relationships of each genus and the ecology of nymphs of each species are discussed.     

Four new species of Cymatodera Gray from Mexico (Coleoptera,Cleridae, Tillinae)

New monogeneans from the bathydemersal southern African endemic catshark,Holohalaelurus regani (Gilchrist, 1922)

The catshark genus Holohalaelurus Fowler is currently represented by five species distributed off the southern and eastern parts of the African coast. Very few parasitological records exist for any of these five species, representing a significant knowledge gap. We report the first monogenean species from the bathydemersal species Holohalaelurus regani (Gilchrist): a new species of Microbothriidae Price, 1936, Leptomicrobothrium holohalaelure n. sp. from the dorsal skin surface, and a new species of Hexabothriidae Price, 1942 representing a new genus, Scyliorhinocotyle narvaezae n. gen., n. sp., from the gill lamellae. Both monogenean records represent the first for any member of the catshark genus Holohalaelurus. Previously we focused on the identification of monogenean taxa of emerging veterinary importance for public aquaria. We now begin a focused effort to document a generally unexplored monogenean biodiversity from diverse marine habitats off South Africa.
