In 1951 to 1955 Mr. N. H. Anderson of the Belleville laboratory, and Mr. C. V. G. Morgan, Entomology Laboratory, Summerland, B.C., collected plant material in southern British Columbia to investigate the distribution there of phytoseiid mites. Many phytoseiids in this material were apparently undescribed, and in 1956 the author collected further specimens. Nine undescribed forms were found; descriptions of these are given below, with a key for identifying the adult females of all phytoseiid species known to occur in British Columbia. The new species all are of the genus Typhlodromus Scheuten, 1957, as defined by Chant (in preparation). The mites were cleared in chloral hydrate or lactic acid and mointed in Berlese's fluid; but some were mounted directly in De Faure's fluid. The measurements given are of the greatest lengths and widths of the dorsal and ventri-anal shields, and whenever possible are the means for 10 specimens. The setal terminology of Garman (1948) and Nesbitt (1951) is followed. All specimens referred to were collected in British Columbia unless otherwise stated.

Adult females and males of Caligus clemensi sp. nov. from the body surface of British Columbia fishes are described. The known hosts are Oncorhynchus kisutch, O. gorbuscha, O. keta, Clupea pallasi, Gasterosteus aculeatus, Hexagrammos sp. and Theragra chalcogrammus. This is the only species of Caligus known from the coastal waters of British Columbia. "Caligus gurnardi Krøyer" of Fraser, 1920, is synonymous with the new species.

Two new species of stenodemine Miridae from western Canada and the United States are described. Trigonotylus exilis n.sp. from British Columbia to northern California and Utah, and T. setosus n. sp. from northern British Columbia, YukonTerritory, and adjacent northern Northwest Territories and Alaska are documented. A key to the species of Trigonotylusfrom this study region is provided to allow identification of the included fauna. Host plant species are identified. Lactic acid is proposed as an alternative to potash as a dissection medium for male genitalia.

In this paper, M. yanomami n. sp., from Brazilian Amazonia, Chaetacis bandeirante n. sp., from Central Brazil, and the males of M. gaujoni Simon, 1897 and M. ruschii (Mello-Leitão, 1945) n. comb. , respectively from Ecuador and Brazil, are described and illustrated for the first time. An ontogenetic series of the last development stages of both sexes of Micrathena excavata (C. L. Koch, 1836) is illustrated and briefly described. Adult females are larger and have longer legs and larger abdomens than adult males. Probably females undergo at least one additional moult before adulthood, compared to males. Micrathena ornata Mello-Leitão, 1932 is considered a junior synonym of M. plana (C. L. Koch, 1836), and M. mastonota Mello-Leitão 1940 is synonymized with M. horrida (Taczanowski, 1873). Acrosoma ruschii Mello-Leitão, 1945 is revalidated, transferred to Micrathena and considered a senior synonym of M. cicuta Gonzaga & Santos, 2004. Chaetacis necopinata (Chickering, 1960) is recorded for Brazil for the first time. Chaetacis incisa (Walckenaer, 1841) is considered a nomen dubium.

The phytoseiid mites of the Cape Verde archipelago are scarcely known. We report the results of a survey conducted on the islands of Santiago and Santo Antão, where phytoseiids were collected from native, cultivated and invasive plants. Fourteen species were collected, four of which represent new records for the islands. One new species, Typhlodromus (Anthoseius) macrodactylus Ferragut sp. nov., is described and illustrated. We describe the unknown male of Amblyseius neolargoensis van der Merwe, provide a redescription of the male of Euseius fustis (Pritchard & Baker) and additional morphological information for all examined species.

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.

Stalked Crinoids

Two new species of deep-sea stalked crinoids belonging to the family Hyocrinidae were collected in the northeastern Pacific. The descriptions contain detailed information on character variations and ontogeny. The five specimens of Gephyrocrinus messingi n. sp. lived at depths ranging from 1,777 m to 2,110 m off British Columbia and California. This new species is the first record of the genus Gephyrocrinus in the Pacific Ocean, which was previously known from only a single species, G. grimaldii, from the northeastern Atlantic at the same depth range. The two species illustrate opposing phenotypes within the same genus. Fifty-eight specimens of the second new species, Ptilocrinus clarki n. sp., were dredged off British Columbia close to the type-locality of P. pinnatus, the type species of the genus Ptilocrinus, but at shallower depths ranging from 1,178 to 1,986 m. This exceptional collection provides significant data on intraspecific variation in the main morphological characters, especially arm pattern. The ontogeny of stalk articulations and the main traits of adoral plate differentiation are described in detail. A complementary investigation on P. pinnatus was conducted using specimens collected by the “Albatross” expedition at a depth of 2,906 m. Despite similarities in external morphology, tegmen and cover plates, the two ptilocrinid species display significant differences in pinnule architecture, aboral cup and stalk articulations. From comparison with Gephyrocrinus messingi n. sp. and Ptilocrinus clarki n. sp., G. grimaldii and P. pinnatus are interpreted as the result of heterochronic development by paedomorphy after ecological or geographic isolation. Pinnule architecture in the two new species suggests first steps in an evolutionary trend toward a rigid box which protects gonad inflation in the proximal part of the pinnule. These new data on Ptilocrinus and Gephyrocrinus create problems in the current taxonomy of the family Hyocrinidae. The main derived characters, especially in pinnule and arm pattern, are used to propose new hypotheses for hyocrinid phylogeny.

A New Species

Occella impi, a new species of sea poacher, is described from a single specimen captured in the Queen Charlotte Islands, British Columbia. Occella impi differs from other species of Occella in having spinous plates on the breast, the anus nearer the anal fin, and fewer anal rays; also, the numbers of bony body plates are distinctive. A key to the known species of Occella, based primarily on the numbers of bony body plates, is included. The size of the maxillary barbel and number of infralateral plates are shown to be characteristic of the genera Occella and Stellerina.
