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.

Closely Related Species

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.

A New Species

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 The habitat preferences and life cycles of the species are quite different (Sweet, unpublished).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.

AbstractCompetition is a basic type of interaction between species. Because complete competitors cannot exist in one habitat, closely related species must show at least slight differences in their biology or ecology. In the present study, we analyzed the habitat use of the two closely related bush-cricket species Tettigonia caudata and T. viridissima which often occur syntopically. The meso- and microhabitat use of males was compared in an agricultural landscape in NE Germany. Males of both species were found to use similar mesohabitats and to prefer dense and high vegetation. Microhabitats differed significantly in two aspects: Microhabitats of T. caudata had a higher proportion of herbs, while T. viridissima used higher song posts. These differences in microhabitats might explain the co-occurrence of the bush-crickets in open habitats. However, variation between the two species might also take place during other life-cycle stages such as during egg development.

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.

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.

Further Development

During the pursuit of field work in the neighbourhood of Warwick in which the collection and examination of insects was involved, it was observed whilst carrying out dissections of dung-infesting beetles that several of them had attached to various parts of the exoskeleton collections of what were at first taken to be fungus spores. On close examination, however, these adherent bodies were discovered to be encysted nematodes which were using the beetles as carrying agents, whereby their transference to fresh dung, required for further development, would be assured.Our attention was drawn to a short note, written by Christie (1925), in which this author discusses the finding of what was either Rhabditis coarctata Leuck. or a closely related species on a number of species of dung beetles in America. With this information in mind, it was decided to culture the worms in order to follow out the life-cycle, determine the species, and make observations on the behaviour of the nematodes in relation to the insects on which they were found attached.

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.
