Since Summers described Bryobia curiosa in 1953 from an unknown host in the Mojave Desert, California, this unusual mite with the stylophore cleft mediodistally has never been reported elsewhere. In 1959, two new, closely related species were discovered: one was found at Summerland, British Columbia, and is described herein; the other was taken in California. I am indebted to Dr. F. M. Summers, University of California, Davis, Calif., for the loan of specimens of B. curiosa and for permitting me to examine specimens of his undescribed species from California.

In the course of current work upon the biology and ecology of the Rhyparochrominae of New England, a new species of Ligyrocoris was discovered. The species runs in Barber's (1921) key to the couplet separating diffusus (Uhler) from sylvestris (L.), but is distinct from either species. While the new species is closely related to these species, it is also quite close to L. depictus which is separated out in a different part of Barber's key.These four closely related species are sympatric in New England, although they are markedly different in their overall distribution. The habitat preferences and life cycles of the species are quite different (Sweet, unpublished). The habitat of the new species described below is most unusual for the genus. The greater part of the type series was collected along the margin of a small pond where sedge clumps were standing in the water among occasional exposed rocks rather than in relatively dry fields or slope habitats where the other species occur. The species feeds upon the seeds of the sedge, Carex stricta Lam, and its life cycle is apparently adapted to that of the sedge, which fruits in late May and June. The insect becomes adult in mid-June and lays eggs until mid-July. The eggs remain in diapause over the summer and winter and hatch in May.

We describe Lepidotrigona satun Attasopa and Bänziger new species from southern Thailand based upon associated males and females (workers). The new species is a member of the L. ventralis species group, which is otherwise represented in Thailand only by L. flavibasis and L. doipaensis. We also describe the males of the latter two species, associated with nests from close to their type localities in northern Thailand. Lepidotrigona doipaensis Schwarz and L. flavibasis (Cockerell) had previously often been misidentified as L. ventralis (Smith), a species confirmed only from Borneo. Based upon differences in male morphology, especially of the metasomal sterna, we conclude that the male described from Vietnam by Sakagami (1975) as belonging to L. flavibasis represents an undescribed species. Our findings support previous taxonomic studies that highlight the importance of including males in the differentiation of closely related species of meliponines and their association with workers. The three species whose males we describe have asymmetric penis valves with the asymmetry differentially developed among the three. We compare this genitalic asymmetry with that known from a different apid genus, Tarsalia.

Early in the summer of 1951 a small collection of aquatic insects was submitted to the author by J. Goodwin of Toronto, taken from Sheldon Creek in Dufferin County, Ontario. Included were nymphs of two readily distinguishable species of Rithrogena, one having bright red gills and the other hyaline whitish gills, Those with hyaline whitish gills were more abundant and proved to be R. impersonata Mc.D. of which specimens from Baddeck, N.S. and Lachine, P.Q. are in the Canadian National Collection at Ottawa. I have records of this species in both nymphal and adult stages from the Credit River, Peel County, Ontario, where the association of nymph and adult was made, and in the nymphal stage from the Saugeen River in Grey County, Ontario. The nymphs with red gills proved to be those of a new species which, considering genitalic characters, is closely related to R. impersonata.

The genus Cheironitis van Lansberge, 1875, currently contains 23 species from the Old World. During a survey for dung beetles in Jordan, specimens of an undescribed species were collected at the historical site of Petra. A new species of Cheironitis (C. petraensis sp. n.) is described from the historical site of Petra, Jordan, illustrated and compared with its most closely related species. This new species is reminiscent of the African species of Cheironitis living in savannahs and could represent a relictual species of the mid-Holocene climatic optimum.

Pimpinella ibradiensis, an unusual new species found in the Toka Yayla (İbradı, Antalya) in southern Anatolia, is described and illustrated. Site conditions, synecology and conservation status of P. ibradiensis are considered. In light of the comparison with the other closely related four species, namely P. nephrophylla, P. flabellifolia, P. sintenisii and P. paucidentata, its similarity within the genus are discussed. P. ibradiensis is easly distinguished from its relatives by its white petals, presence of bracts and bracteoles, larger fruits (4–5.5 × 1–2 mm), and having serrulate basal leaves with 60–95 strongly cartilaginous teeth along margins. The geographical distribution of P. ibradiensis and closely related species are mapped and the identification key of those species is updated.

A new species of Trogia (Marasmiaceae, Basidiomycota) is described from West Bengal, India. Analysis of the molecular sequence (nuclear ribosomal internal transcribed spacer region) data suggests that T. benghalesis is phylogenetically distinct from its closely related species. Comprehensive description based on macro- and microscopic characters, photographs and comparisons with morphologically similar and phylogenetically related species are provided.

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.

Lampetra macrostoma n.sp., a freshwater parasitic lamprey, is distinguished from related species L. tridentata, L. lethophaga, L. folletti, L. minima, and L. similis by its parasitic habit and very large disc. Other characters distinguishing the species from L. tridentata are its longer prebranchial length, large eye, weakly pigmented velar tentacles, and its ability to remain in freshwater. The recently metamorphosed form readily survives in freshwater and probably is non-anadromous even though it can survive in salt water. The new species has been discovered in two lakes on Vancouver Island, British Columbia, Canada, where it attacks large numbers of resident salmonids. Because of its ability to survive and feed in freshwater, it poses a definite threat to freshwater fishes.Key words: lamprey, new species, non-anadromous lamprey, salmonid parasitism

Spinicauda anurae sp. nov. from the intestine of Duttaphrynus melanostictus [21] collected from industrial area of Aurangabad (M.S.) India. The specimens under investigation show the resemblance in their various body characters with S. cophotis Baylis, [7]. Morphologically the most closely related species is S. voltaensis [2] in Bufo sp. from Burkina Faso, but it differs in smooth cuticle and is less sclerotized.
