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.

AbstractLast instar larvae and the pupae of Gluphisia avimacula, Notodonta simplaria, Dasylophia thyatiroides and Hyparpax perophoroides are described, compared with those of related species, and in part figured. Various ecological aspects are discussed and host plant information is provided in each case, with comments on the number of generations, times of occurrence and, with respect to simplaria and thyatiroides, on the regional prevalence of melanism.

Unusual Shape

AbstractThe gall-making sawfly, Pontania (Eupontania) aestiva (Thomson, 1862) (= P. norvegica Kopelke, 1991, ?P. varia Kopelke, 1991) is treated as a valid species. The lectotype of Nematus aestivus Thomson, 1862 is redescribed. Pontania aestiva produces leaf-galls on Salix myrsinifolia (= nigricans, borealis) in Northern Europe and probably in the mountains of Central Europe. Populations of this species from the British Isles are considered as a separate subspecies, P. aestiva harrisoni Benson, 1940. Galls found on Salix purpurea x viminalis and S. purpurea in Northern England and Southern Scotland have an unusual shape, which probably is correlated with development on a subsidiary host plant. Similar host induced differences have been shown for P. viminalis (Linnaeus, 1758), which has normal galls on Salix purpurea, but abnormal galls on Salix babylonica reared under laboratory conditions. Morphological differences of adults are described to differentiate the sawfly species.

The Relationship

The adult females of two new species of Diaspididae (Hemiptera: Coccoidea) are described and placed in Anzaspis Henderson(previously only known from New Zealand): A. neocordylinidis Łagowska & Hodgson and A. pandani Łagowska & Hodgson.The former is close to A. cordylinidis (Maskell), currently only known from New Zealand and found on the same host plantspecies, and the latter is very close to Chionaspis pandanicola Williams & Watson, only currently known from Fiji, and alsocollected on the same host plant species. Two previously described Chionaspis species already known from Fiji, i.e. C.freycinetiae Williams & Watson and C. pandanicola Williams & Watson are transferred to Anzaspis as Anzaspis freycinetiae(Williams & Watson) comb. nov. and A. pandanicola (Williams & Watson) comb. nov., and a third species, C. rhaphidophoraeWilliams & Watson, is transferred to Serenaspis as Serenaspis rhaphidophorae (Williams & Watson) comb. nov.. The reasonsfor these nomenclatural decisions and the relationship between the scale insect fauna of Fiji and New Zealand are discussed. A key is provided to all related species in the tropical South Pacific and New Zealand.

Gonioctena koryeoensis sp. nov. (Coleoptera: Chrysomelidae: Chrysomelinae) is described based on adults, larvae, and pupae collected from the southeastern Korean Peninsula. The new species is easily distinguished from related species by coloration, size, length ratio of antennal segments, and shape of aedeagus. The larva and pupa are also distinguished from all other known species by the tubercle pattern and the apical processes of the ninth abdominal segment, respectively. Notes on distribution, host plant, and ovoviviparity are included.

Cymbidium lii (Orchidaceae: Epidedroideae: Cymbidiinae), endemic to Hainan, China and the only one well-developed rhizome epiphytic species ever found in the genus, is newly described. A detailed morphology comparison including the seed characters between the newly discovered orchid and the related species was conducted. A local palm, Livistona saribus (Lour.) Merr. ex A. Chev was found to be the unique host plant. It is considered to be critically endangered according to the latest IUCN Red List criteria.

Preimaginal Stages

The larval stages ofLasioptera donacisCoutin consist of three instars which develop within the mesophyll of the leaf sheaths ofArundo donax(L.) (Poaceae). The larvae feed aggregatively on mycelia of an ambrosia fungus. The third instars are similar to other members of the genus except for a three-pronged spatula (typically two-pronged) and five lateral papillae (typically four) and with a nonbristled first instar. A related species,L. arundinis(Schiner) which breeds on fungus inPhragmites(Poaceae), also has a three-pronged spatula and five lateral papillae but has a bristled first instar. The third instar ofL. donacishas a feeding and a nonfeeding prepupal stage. Papillae associated with the spatula are sensory organs, sensilla chaetica, sensilla trichodea, and sensilla ampullacea, perhaps related to extraoral digestion of the fungal mycelia. Pupation occurs in the host plant within a silken cocoon. Egression of the adult is through an escape hatch excavated by the third instar.
