A New Species

From a study of living materials and specimens in several regional herbaria, a list has been drawn up of all the common and several of the rarer tube-dwelling diatoms of eastern Canada. Descriptions, illustrations of living material and acid-cleaned valves, and a key to the species are provided. Most specimens were from the Atlantic Provinces and the St. Lawrence estuary, but a few were from the Northwest Territories. By far the most common species is Berkeleya rutilans. Other species occurring commonly in the Quoddy Region of the Bay of Fundy, and sporadically in space and time elsewhere, arc Navicula delognei (two forms), Nav. pseudocomoides, Nav. smithii, Haslea crucigera, and a new species, Nav.rusticensis. Navicula ramosissima and Nav. mollis in eastern Canada are usually found as scattered cohabitants in tubes of other species. Nitzschia tubicola and Nz. fontifuga also occur sporadically as cohabitants.

A New Species

Chaetopterus is a globally distributed genus of marine Annelida with a long history of taxonomic confusion. Here, we describe Chaetopterus bruneli sp. nov. from a depth of 350 m in the St. Lawrence Estuary, eastern Canada. The new species represents the northernmost record for Chaetopterus in the western Atlantic to date. The similar European species Chaetopterus norvegicus M. Sars, 1835 is resurrected from long-standing synonymy and redescribed from type material, and a lectotype is designated.

A New Species

Checking some North American genera of bark-beetles I found a series of Alniphagus Sw. which does not agree with the common species Alniphagus aspericollis from California and British Columbia and doubtless represents a new species. The genus therefore comprises now three distinct species, Alniphagus alni Nijs. from Japan and the Far East, A. aspericollis from British Columbia down to California and the new species A. hirsutus from Alnus sitchensis in B.C.

Hoya soidaoensis is proposed as a new species from Khao Soi Dao, Chanthaburi Province, Southeastern (SE) Thailand. This newly revealed species is thoroughly described, discussed and illustrated. This species is related to the common species H. caudata and H. flagellata, but they have quite different leaves, flowers and habitats.

A new species, Strobilomyces pteroreticulosporus, is described based on two recent collections from the Republic of Korea. This new taxon is well characterized by morphological characters, and proved using rpb1 and ITS2 sequences. The variability of size and basidiospore ornamentation of the common species S. confusus is also discussed.

A New Species

The following is a description of a new species of leafhopper from Eastern Canada of the subgenus Cloanthanus of the genus Scaphytopius. A key to the known Canadian species of Cloanthanus is included. Two of these species, angustatus (Osb.) and argutus DeL., do not appear to have been recorded previously for Canada. The key is based primarily on structures of the male genitalia, as these show the most reliable specific characters. External characters of colour, markings, and structure are often unreliable, because of the variation that occurs. There is occasionally some variation in the genitalic characters, notably in the degrees of curvature of the paraphyses, but the general shape of each structure is sufficiently constant to provide reliable specific characters. This subgenus, which was revised by Hepner (1947), is poorly represented in Canada, as the majority of the species have southerly distributions in North America. The common Canadian species is acutus (Say), followed by latus (Baker); the remaining species are more restricted in their ranges and distributions in Canada.

A New Species

In a paper by Mr E. W. Binney on the Fossil Fishes of the Pendleton Coal Field, published in 1841, the dentary bone of Rhizodopsis is figured as the “upper jaw of a new species of Holoptychius,” to which, however, he did not attach any specific name. In the same paper its scales are also figured and referred to the same genus. Scales belonging to the same fish were afterwards figured by Professor Williamson under the name of Holoptychius sauroides, and again by Mr Salter, as those of Rhizodus granulatus. Both of these specific names occur under Holoptychius in Agassiz's general list of Ganoids published in 1843, but as they were unaccompanied either by figures or descriptions, it is really immaterial which of them, if indeed either, was applied by him to the fish in question. The authority for the term “sauroides” as applied to the common species of Rhizodopsis, the only species of the genus which is as yet known with certainty, must therefore remain with Professor Williamson. Holoptychius sauroides of Binney and of Messrs Kirkby and Atthey is quite another fish, now also distinguished generically as Strepsodus, and for it the specific name “sauroides” is therefore equally valid.

A new species of Stephanostomum Looss, 1899 (Digenea, Acanthocolpidae) with a bizarre oral sucker: S. adlardi sp. nov. from the common coral trout Plectropomus leopardus (Lacepède, 1802) (Perciformes, Serranidae) from Lizard Island, Great Barrier Reef

AbstractA new species of Acanthocolpidae, Stephanostomum adlardi is described from the serranid Plectropomus leopardus from Lizard Island in the northern Great Barrier Reef. It differs from all previously described acanthocolpids in the structure of the oral sucker which is extended into dorsal and ventral lobes each bearing a row of spines. A phylogenetic tree estimated from combined nuclear small and partial large ribosomal RNA gene sequences shows that, despite the unusual oral sucker structure, the species is a true member of the genus Stephanostomum. The molecular results also suggest that Monostephanostomum nolani is derived from within Stephanostomum.

A new species of tree cricket, Neoxabea mexicanasp. nov., is described from northeast Mexico. Although it has morphological similarities to two other species found in Mexico, there are distinguishing characters, such as a well-developed tubercle on the pedicel, black markings on the maxillary palpi, one of the two pairs of spots on the female wings positioned at the base of the wings, stridulatory teeth count, and the pulse rate of the male calling song. The calling song description and pre-singing stuttering frequencies are provided. Character comparisons that rule out other species in the genus are presented. The common name given to this new species is Mexican tree cricket. Sound recordings and video are available online. We also make some clarification of the status of Neoxabea formosa (Walker, 1869), described as Oecanthus formosus, and present a key of Neoxabea in North and Central America.

A New Species

A new species of Oecanthus is described from extreme northeast California. Oecanthus salviisp. nov. is currently known only from Lake Annie in Modoc County, California, and occurs on sagebrush (Artemisia) and rabbitbrush (Ericameria). It has the narrow tegmina, antennal markings, metanotal gland configuration, and trilling song found in the Oecanthus nigricornis species group. Song details and morphology, including the shape of the subgenital plate and copulatory blades, are provided in this paper. This new species has been given the common name of sage tree cricket.
