Saprophytic Ability

The stem blight pathogen, Phomopsis emicis, is widespread on Emex australis throughout those regions of southern Australia with a Mediterranean climate. Host specificity tests showed that P. emicis was able to cause leaf lesions or stem collapse on five closely related species, E. australis, E. spinosa, Rumex alcockii, R. dumosus and R. pulcher, in the Polygonaceae. Two of these species, R. alcockii and R. dumosus, are native to Australia and the others are introduced weeds. P. emicis was able to colonize the wounded or senescent tissue of several other plant species, thereby demonstrating its facultative saprophytic ability. There was evidence that P. emicis was able to survive as an endophyte in Muehlenbeckia adpressa and Polygonum aviculare.

Host Plant Specificity

Bryobia praetiosa Koch (1836) was formerly regarded as a complex of closely related species or races similar in morphological characters but varying widely in life-history, host plant specificity, and habits. The authors (30) have recently shown that two species, the clover mite, B. praetiosa Koch, and the brown mite, B. arborea Morgan and Anderson, can be distinguished in British Columbia on the basis of morphological characters. This paper presents ecological data in support of the morphological evidence.

Intraspecific Morphological Variation

AbstractMorphological variation between two closely related species in the genus Amblyseius Berlese was examined by numerical taxonomic methods. Multivariate tests indicated that A. canadensis Chant and Hansell and A. novaescotiae (Chant) represent two separate and distinct morphological groups. This supports their taxonomic retention as valid species. Intraspecific morphological variation was also examined and found to be correlated with climatic and host plant variables.

The Elachista regificella complex (Elachistidae) is revised and considered to consist of three closely related species: E. regificella Sircom, presently only recorded from Great Britain, E. geminatella (Herrich-Schäffer), stat. rev. (= E. nieukerkeni Traugott-Olsen, syn. nov.) and E. tengstromi nom. nov. (= E. magnificella Tengström, 1848, nec Duponchel, 1843). The latter two species are widely distributed e.g. in Central Europe, the range of E. tengstromi extending to Japan. The species are diagnosed and illustrated. Life history records indicate that the species have, at least to some extent, different host plant preferences: Luzula sylvatica is recorded as the host plant of E. regificella and E. geminatella, of which the latter probably exploits other host plants as well. L. pilosa is the only known host plant of E. tengstromi in Europe, with further host plants recorded in Japan. Neotypes are designated for Elachista regificella Sircom and Poeciloptilia geminatella Herrich-Schäffer.

AbstractIn sawfly taxonomy the structure of the lancet or the saw is an important character for identification of females. Because adult females use the saw to place eggs into the host plant its teeth may wear and their shape may thus be altered. We investigated the pattern of wear in a species of nematine sawfly that we also describe for the first time. Saw wear of females that deposited known numbers of eggs was examined. Saw wear was not strongly related to the number of eggs laid, despite some saws being considerably worn. The range of variation in saw profile illustrated by Lindqvist (1956) in the closely-related species D. virididorsata (Retzius) was not observed in our study. Despite the shape of the saw being altered to some extent with use, other structures on the saw do not change and provide good taxonomic characters in the genus Dineura, as evidenced by our detection of the cryptic (= sibling) species on the basis of differences in ctenidial structure. We describe this species under the name Dineura pullior sp. n.

A New Species

A new species of pyrenomycete, Nodulosphaeria edgari, is described from western Canada and western U.S.A. A closely related species, Nodulosphaeria olivacea (Ellis) L. Holm, is redescribed from the lectotype and additional collections from western U.S.A. The two species sometimes occur together on the same host plant material. Nodulosphaeria edgari was previously reported from western U.S.A. under the misapplied names Leptosphaeria erigerontis (Berlese) Berlese and Nodulosphaeria olivacea. Species concepts are stabilized based on type studies of the three taxa. Host plant and geographic records are revised.

A New Species

AbstractThe pupal cremasters of twelve species of Japanese oak-feeding Phyllonorycter are examined. The cremasters, even those of closely related species, are specifically distinct. Combined with descriptions of European and North American species, the present results indicate that the cremaster can be used as a diagnostic character for the species of Phyllonorycter. A new species, P. persimilis, which was previously confused with P. similis Kumata, and the female of P. nipponicella (Issiki), hitherto unknown, are described. The nipponicella complex including these species is reviewed and the speciation of its members is discussed in relation to diversification of the host plant preference.

First Time

Nine species of Ancylosis are recorded from Ukraine. Ancylosis larissae sp. nov. related to A. hellenica (Staudinger, 1870) and A. rhodochrella (Herrich-Schäffer, 1852), is described from Crimea. Ancylosis albicosta (Staudinger, 1870) is reported from Ukraine for the first time. Ancylosis albidella Ragonot, 1888, A. syrtella (Ragonot, 1887), A. rhodochrella, A. harmoniella (Ragonot, 1887) and A. monella Roesler, 1973 are removed from the list of Pyralidae of Ukraine due to misidentifications. The host plants for A. sareptalla (Herrich-Schäffer, 1861) and A. substratellum (Christoph, 1877) comb. nov. are recorded for the first time. New host plant is recorded for A. roscidella (Eversmann, 1844). The diagnoses for all species known from Ukraine are provided. The adults and genitalia of both sexes are illustrated for all Ukrainian species and some closely related species from adjacent territories. A key to the species is given based on external characters and the genitalia of both sexes. The female genitalia of A. deserticola (Staudinger, 1870), A. hellenica (Staudinger, 1870), A. sabulosella (Staudinger, 1879) as well as the male genitalia of A. pallida (Staudinger, 1870) are described and illustrated as they have been dealt incorrectly in literature. The status of A. albidella and the records of this species from Europe are discussed. The new synonymy is proposed: Ancylosoma Roesler, 1973 syn. nov. of Ancylosis Zeller, 1839 and A. sareptalla gulbaharensis Roesler, 1973 syn. nov. of A. sareptalla (Herrich-Schäffer, 1861). Ancylosis decolorella (Ragonot & Hampson, 1901) spec. rev., stat. nov. is taken out from synonymy with A. sabulosella. The lectotype of Myelois deserticola Staudinger, 1870 is designated.

Developmental Condition

AbstractDiplolepis triforma n. sp. is described and distinguished from other members of the genus. Diagnoses are given for closely related species: D. ashmeadi (Beut.), D. inconspicuis Dailey and Campbell, D. nodulosa (Beut.), and D. verna (O.S.). Lectotypes are designated for D. ashmeadi, D. nodulosa, and D. verna. The genus Diplolepis Fourcroy is briefly reviewed. The biology and ecology of D. triforma and its gall are described. Diplolepis triforma induces a multichambered, polymorphic stem gall on Rosa acicularis and is distributed throughout central and western Canada. The form of the gall depends on the developmental condition of the host plant at the time of oviposition.
