Felt (1940) mentioned a midge in Douglas-fir needles which he called Cecidomyia sp.; this reference was quoted by Barnes (1951). Denton (1954) reported that a midge, identified by the Division of Insect Identification, United States Bureau of Entomology and Plant Quarantine as Cecidomyia sp., occurred in needles of Douglas fir in northeastern Washington, northern Idaho, and northeastern Montana. In 1954 the author reared some adults which H. F. Barnes (in litt. 1957) referred to the genus Contarinia Rond. Unpublished records from 1935 to date indicate unidentified needle-inhabiting gall midges throughout most of the host range. Recently the author found indications of a species comples which were confirmed by further rearings of adults. This paper presents the description of three new species of Contarinia Rond., reared under similar conditions, from material obtained at Oyama, B.C.

AbstractIn seed orchards of Douglas-fir, Pseudotsuga menziesii (Mirbel) Franco (Pinaceae), located in Washington State and Oregon, United States, we tested whether catches of male Douglas-fir cone gall midges, Contarinia oregonensis Foote, in pheromone-baited traps can be used to predict the extent of galled scales (= seed loss at harvest) caused by developing larvae. In 2000, 27 experimental blocks (4–7 ha each) were selected. In each block we recorded mean numbers of (i) male C. oregonensis captured in 20 pheromone-baited Wing traps, (ii) egg-infested scales in up to 50 conelets in early spring, and (iii) galled scales in up to 50 cones in late summer. In 2001, the experiment was repeated with 20 Delta traps in each of 26 experimental blocks. Moreover, catches of C. oregonensis and nontarget insects in Delta traps and Wing traps were compared in one additional orchard block in 2001. In both years there were positive correlations between mean numbers of egg-infested and galled scales and between mean numbers of captured male C. oregonensis and mean numbers of both egg-infested and galled scales, particularly when only experimental blocks with ≥50% of trees bearing at least 5 conelets were considered. Our results suggest that 4 or 2 captured male C. oregonensis in Wing or Delta traps, respectively, warrant insecticidal control of C. oregonensis. Delta traps, which captured fewer nontarget insects, would be more suitable than Wing traps for operational implementation of this technology.

Three New Species

AbstractThe genus Ericydeus Pascoe (Polydrosinae: Naupactini) distributed throughout the United States of America up to Argentina is revised and a cladistic analysis including 16 species is conducted. Three new species are described: E. bahiensis, E. argentinensis and E. cupreolus. Ericydeus humeralis Hustache is synonymized under E. nigropunctatus (Chevrolat); and E. modestus viridans (Boheman) and E. modestus duodecimpunctatus (Dalla-Torre, Emden & Emden) are elevated to species rank. Other valid species are: E. hancocki (Kirby), E. schoenherri (Perty), E. sedecimpunctatus (Linnaeus), E. yucatanus (Champion), E. roseiventris (Champion), E. quadripunctatus (Champion), E. modestus (Gyllenhal), E. forreri (Champion), E. lautus (LeConte) and E. placidus (Horn). In the cladogram obtained the species from South America gather in a clade (E. argentinensis, E. sedecimpunctatus, E. nigropunctatus, E. schoenherri, E. hancocki, and E. bahiensis) and the species from Central and North America form a separate clade (E. yucatanus, E. roseiventris - E. quadripunctatus, E. cupreolus, E. viridans - E. modestus, E. duodecimpunctatus, E. forreri, E. lautus - E. placidus). The character evolution follows a southern-northern direction. The paper includes a redescription of the genus, redescriptions or descriptions of its 16 species, a dichotomous key, habitus photographs, drawings of diagnostic structures, distribution maps, a cladogram, and a discussion of the phylogeny and distribution of the genus.

Three new species of ascomycetes and two coelomycetes are described from diseased Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) from coastal British Columbia, Canada, viz., Coccomyces pseudotsugae n. sp., Phragmoporthe pseudotsugae n. sp., and Botryosphaeria pseudotsugae n. sp.; Phomopsis portei n. sp. and Haplosporella sp. are associated with the latter two ascomycetes, respectively, and possibly represent their conidial states.

Three New Species

Although Africa and Indonesia have not been particularly well surveyed for Mycosphaerella leaf spot fungi, several species are known to occur on Eucalyptus leaves in these areas. Three new species of Mycosphaerella with anamorph states are described from herbarium specimens and cultures in the present study. Mycosphaerella suttoniae and Mycosphaerella heimioides are described from Eucalyptus leaves from Indonesia. The former species is of particular interest, because its anamorph Phaeophleospora epicoccoides is the first species of Phaeophleospora linked to Mycosphaerella. Mycosphaerella irregulariramosa is described from Eucalyptus saligna growing in the Northern Province of South Africa. Both M. irregulariramosa and M. heimioides have Pseudocercospora anamorphs, and these are described as Pseudocercospora irregulariramosa and Pseudocercospora heimioides. Notes are also provided on the host range and geographic distribution of previously described species of Mycosphaerella on Eucalyptus leaves in other parts of Africa and in Indonesia. Key words: Eucalyptus, Kirramyces, Mycosphaerella, Phaeophleospora, Pseudocercospora, systematics.

Three New Species

The morphology, cytology, distribution, and phylogeny of eight species of the southwestern United States closely related to Cirsium arizonicum are considered. These species form a natural group distinguished from other North American species of Cirsium by a short stigma (1–3 mm) and long corolla lobes (10–20 mm) which are longer than the corolla throat. Three new species described are C. chellyense, C. chuskaense, and C. navajoense. Original chromosome counts are presented for C. nidulum, 2n = 34; C. rothrockii, 2n = 30; C. arizonicum, n = 15; C. chuskaense, 2n = 34; and C. arizonicum × nidulum, 2n = 32, 34.
