Pselaphotumulus,a new genus of pselaphine endemic to New Zealand (Coleoptera: Staphylinidae: Pselaphinae: Pselaphitae)

ABSTRACT

Pselaphotumulus Owens and Carlton, gen. nov., is described as the sixth genus in the tribe Pselaphini known from New Zealand. Three new species are described: Pselaphotumulus aorerei, sp. nov., Pselaphotumulus dubius, sp. nov. and Pselaphotumulus unus, sp. nov.. Three species, Pselaphus cavelli (Broun 1893), Pselaphus oviceps (Broun 1917) and Pselaphus urquharti (Broun 1917) are transferred to Pselaphotumulus, nov. combs. Lectotypes from type series in the New Zealand Broun Collection (Natural History Museum, London) are designated for these three species. Habitus photographs, distributional maps and line drawings of diagnostic characters are provided for each species. A key to species is provided. Searches of museum collections have not yielded representatives outside of New Zealand, suggesting that this is the first endemic genus in the tribe Pselaphini described from the New Zealand’s main islands, specifically, the South Island. Pselaphotumulus species exhibit restricted distribution patterns that approximately coincide with the Pacific/Indo Australian Plate boundary.     

Protrellus dixoni n. sp. (Nematoda: Thelastomatidae) from the cockroach Drymaplaneta variegata

Abstract

In New Zealand, Protrellus dixoni n. sp. occurs in the hind gut of the introduced Australian cockroach Drymaplaneta variegata. It is distinguished from all other Protrellus species by its morphology. Females have a well developed muscular ovijector with a sphincter, and a conical tail with a filiform projection; males have four, not three, tail papillae. The taxonomic history of the genus is discussed and the generic diagnosis emended. New combinations include Protrellus eurycotesi, P. ischnopterae, P. ituana, and P. gurri. The population structure of P. dixoni in adult hosts is described: there are never more than one adult male, and usually few (one to three) adult females per host.     

Revision of New Zealand Orthotylinae (Insecta: Hemiptera: Miridae)

Abstract

Six genera and 11 species of Orthotylinae are now known from New Zealand. Zanchius Distant is newly recorded. One new genus, Tridiplous, and seven new species of endemic New Zealand Orthotylini are described and illustrated. Four new species are described in Tridiplous: T. burrus, T. parvapiatus, T. penmani, and T. virens, and three new species are described in Zanchius: Z. ater, Z. rubicrux, and Z. totus. Keys are provided to identify New Zealand taxa of the tribes of Orthotylinae, genera and species of Halticini, genera of Orthotylini, and species of Tridiplous and Zanchius. The bugs are illustrated with colour habitus photos, and drawings including male and female genitalia. Economic importance is discussed.     

New species of Halacaridae (Acari) from New Zealand

Abstract

Seven new taxa of marine mites (Halacaridae) are described from the marine littoral zone of northern and southern New Zealand: Agauopsis novaezelandiae, A. luxtoni, Halacarellus lubricus, Copidognathus lubricus, Simognathus glaber, S. glareus, and Rhombognathus novaezelandicus. A list of halacarid species known from New Zealand waters is added.     

New species and records of Stigmaeidae (Acari: Prostigmata) from New Zealand - ID. Genus Stigmaeus Koch

Abstract

Stigmaeus arboricola, S. montanus, S. luxtoni, and S. novazealandicus are described as new species, and the larva of S. loadmani is described. Several new records are noted, and a key is given to the New Zealand species of Stigmaeus.     

The recent New Zealand species of Triforis (Gastropoda: Triforidae)

Paramendax apicina Powell and Mendax attenuatispira Powell are referred to genus Triforis Deshayes; T. antepallaxa, T. blacki, and T. tui are described as new; and a species close to the South Australian Triforis epallaxa (Verco) is recorded from New Zealand waters. Paramendax Powell is transferred from the Cerithiopsidae to the Triforidae as a subgenus of Triforis. It is suggested that the Recent South African Cerithiella nonnitens Barnard is referable to Triforis.     

Deltocephalinae of New Zealand (Homoptera: Cicadellidae)

The subfamily Deltocephalinae is represented in New Zealand by 3 tribes, 9 genera, and 20 species, of which 3 genera and 13 species are new to science. All taxa are described, and keys are given for their separation. Three of the genera are endemic, 3 are Australian, 2 are Holarctic, and 1 is cosmopolitan. Nesoclutha and Macrosteles are recorded in New Zealand for the first time, and the presence of Deltocephalus is authenticated. Fourteen species are endemic, 4 are Australian, 1 is widespread in the Pacific area, and 1 is Holarctic. Nesoclutha pallida, Macrosteles fieberi, and Deltocephalus hospes are recorded in New Zealand for the first time.     

A new genus and species of deepwater codfish (Pisces: Moridae) from New Zealand

Abstract

Momonatira globosus, a new monotypic genus and species of Moridae, is described from five specimens taken in 1153–1184 m from South Canterbury Bight, New Zealand. Spindle shaped otoliths indicate affinities with genera within the Physiculus group. Momonatira is distinctive in having broad fleshy bases to the dorsal and anal fins; a very large globular head; no light organ or barbel; 5–6 rays in the ventral fin; the lower jaw included and in other characters.     

Mnioloma fuscum (Marchantiopsida: Calypogeiaceae), an unexpected addition to the indigenous flora of New Zealand

Abstract

Mnioloma fuscum, a liverwort species known to date primarily from tropical-montane regions, is reported for New Zealand for the first time. Its occurrence in New Zealand is unexpected as the next nearest known site is believed to be the Solomon Islands, some 3500 km distant. The occurrence of Mnioloma fuscum in New Zealand highlights the contribution tropical regions have made to the composition of New Zealand's hepatic flora.     

Description of Kiefferulus opalensis n.sp. (Diptera: Chironomidae)

A new species of Kiefferulus Goetghebuer is described and compared with species from Australia. This is the first record of the genus in New Zealand.

New records of Conidae (Mollusca: Gastropoda) from the New Zealand region

Abstract

Conus howelli Iredale is recorded from New Zealand. C. howelli and C. raoulensis Powell are considered to be very closely related, and Kermasprella Powell is thus probably a svnonvm of Endemoconus Iredale. C. teramachii (Kuroda) and C. smirna Bartsch ' Rehder are recorded from off northern New Zealand, and the known range of C. kermadecensis Iredale is extended southward.     

Profilicollis novaezelandensis n. sp. (Polymorphidae) and two other acanthocephalan parasites from shore birds (Haematopodidae and Scolopacidae) in New Zealand,with records of two species in intertidal crabs (Decapoda: Grapsidae and Ocypodidae)

Profilicollis novaezelandensis n. sp. (Acanthocephala: Polymorphidae) is described from the South Island pied oystercatcher Haematopus ostralegus finschi Martens (Haematopodidae) and the intertidal crab Hemigrapsus crenulatus (Milne Edwards) (Brachyura: Grapsidae) from the South Island of New Zealand. The new species can be distinguished from all the other species of the genus by a combination of the following characters: long neck (13% of total body length for adults) and a subspherical proboscis with 14–16 longitudinal rows of 7–8 hooks. The mud crabs Helice crassa Dana (Grapsidae) and Macrophthalmus hirtipes (Heller) (Ocypodidae) were also harbouring cystacanths and the bar-tailed godwit Limosa lapponica (Linnaeus) (Scolopacidae) juveniles of P. novaezelandensis. This is the first record of brachyuran decapods as intermediate hosts of Acanthocephala from New Zealand. P. antarcticus is recorded from three crab species (Helice crassa, Hemigraspus crenulatus and Macrophthalmus hirtipes) and two bird species (Haematopus o. finschi and Limosa lapponica) in New Zealand. An unidentified species of Plagiorhynchus was also found in two bird species (H. o. finschi and H. unicolor Forster). P. antarcticus and P. novaezelandensis are the first records of Profilicollis from New Zealand.     

Polytrichum commune Hedw. and Polytrichadelphus magellanicus (Hedw.) Mitt. used as decorative material on New Zealand Maori cloaks

Abstract

Confirmation of the occurrence of the moss Ptychomnion densifolium on the main islands of New Zealand is provided and the features which separate it from the more common P. aciculare are outlined. A brief account of the history of P. densifolium in New Zealand is given and its morphology there is discussed. A key to the two species in New Zealand is provided and habitat differences between them outlined. New Zealand material differs from type locality (Tristan d' Acunha) material in having longer and more twisted acumens, and in this respect is similar to New Zealand material of P. aciculare. New Zealand populations of P. densifolium are recognisable in having stem leaves reflexed from an oblong sheathing base, and well developed basal leaf plications. It is a relatively widespread species in New Zealand, occurring in mostly upper elevation, open sites.     

Chilocoris neozealandicus,a new species of burrowing bug from New Zealand (Heteroptera: Cydnidae)

Abstract

The Old World cydnid genus Chilocoris Mayr is recorded from the Australasian region for the first time. A key is provided separating Chilocoris from Centrostephus Horvath and Parachilocoris Horvath. A new species, Chilocoris neozealandicus, is described from New Zealand, along with habitus drawing and illustrations of diagnostic characters.     

Life history stages and taxonomy of Austrosimulium (Austrosimulium) tillyardianum (Diptera: Simuliidae)

The male, female, pupa, 9th‐instar larva, and egg of Austrosimulium (Austrosimulium) tillyardianum Dumbleton, 1973, are redescribed, and larval instars one to eight are described and morphologically differentiated for the first time. The relationship of A. (A.) tillyardianum to other New Zealand species is briefly reviewed.     

First record of Sitona discoideus Gyllenhal 1834 (Coleoptera: Curculionidae) on Norfolk Island

Abstract

The first records of Sitona discoideus and Trifolium repens on Norfolk Island are reported. The identities of both species were confirmed using morphological criteria and nucleotide sequences. Sequence data from the mitochondrial gene cytochrome oxidase subunit 1 of the Norfolk Island S. discoideus specimens were compared with 33 specimens from Australia, New Zealand and France. These data represent the first published sequences for S. discoideus, and suggest that Australia or New Zealand was the source of Norfolk Island's population. The implications of the introduction of S. discoideus to Norfolk Island are discussed.     

Pallial systems in the Athoracophoridae (Gastropoda: Pulmonata)

Abstract

Pallial systems are described for 10 athoracophorid species: Athoracophorus bitentaculatus, Pseudaneitea dendyi, P. gigantea, P. papillata, P. pallida, P. aspera, P. schauinslandi, P. multistriata, and Palliopodex verrucosus from the New Zealand and sub antarctic area; and Triboniophorus graeffei from Australia. In the New Zealand and subantarctic species the kidney is invariably bilobed, the ureter is extensively folded and connected to the intestine by an elongate tubule running initially through the lung, and the pneumostome, anus, and excretory pores are widely sepamted. Triboniophorus graeffei has the pneumostome, anus, and excretory pore closely associated, a compact kidney, and a more simply folded ureter. The New Zealand and subantarctic representatives are considered to be more advanced. Reasons for the development of the features they display are discussed, as is the function and evolution of the entire pallial system. An account of the variation in the pallial complex of Athoracophorus bitentaculatus is included.     

The first record for Melittobia australica Girault in New Zealand and new host records for Melittobia (Eulophidae)

Abstract

Melittobia australica Girault is a new record for New Zealand and from Vespula spp. In the Wellington district, M. australica was found in an embryo colony of the German wasp Vespula germanica (Fabricius) and in pupae of the mason wasp Pison spinolae Shuckard in 1980 and 1981 respectively. Melittobia was recorded in nests of P. morosum Smith in Canterbury, New Zealand in 1976 and 1977. The original sources of M. australica were considered.

The validity of the earliest record of Melittobia in a social wasp host is reconsidered. It is concluded Melittobia has been underated as a parasite of social wasps.
