In the Enchytraeidae, species separation and identification is often problematic due to high morphological similarity of closely related species and considerable intraspecific variability of crucial characteristics. Immature specimens are almost undeterminable. To meet these difficulties, this paper recommends the consulting of general protein patterns as exhibited by non-specific silver-staining after isoelectric focusing. A method is presented which allows the successful inclusion of protein data in taxonomic studies and field surveys. Two examples from an investigation on Fridericia field populations show that, with the help of general protein pattern analysis, a clear taxonomic decision on the identity of morphologically aberrant forms and of juvenile specimens as well can be achieved with comparatively little expenditure of time. A combined use of morphological and protein data for taxonomic purposes is suggested.  相似文献

The morphology, anatomy and reproduction (tetrasporic, male and female) of a poorly known species of Gracilaria i.e. G. damaecornis J. Agardh was studied, using material collected in eastern Venezuela. Spermatangia are produced in well-defined and deeply immersed multicavitied conceptacles (m type). Nutritive filaments are present both at the floor and top (outer pericarp) of the cystocarp. The lectotype of G. damaecornis is illustrated for the first time. Hydropuntia albornozii (Rodríguez) Wynne (Polycavernosa albornozzi) is shown to be a synonym of G. damaecornis. In agreement with recent research, it is concluded that generic attributes of Hydropuntia ( = Polycavernosa) based on mainly on sexual reproductive structures are of doubtful taxonomic value.  相似文献

The non-indigenous pest leaf miner Liriomyza huidobrensis and its close relatives L. bryoniae and L. strigata belong to a natural group. These species can be separated from one another by means of protein electrophoresis on a cellulose acetate membrane. The protocol for this diagnostic assay involves staining for two enzymes, glucose-6-phosphate dehydrogenase (G6PDH) and leucine-glycine peptidase (PEP). Other leaf miner species that might also be found under glass, Chromatomyia syngenesiae, C. horticola and the non-indigenous L. trifolii and L. sativae , are clearly distinguishable from the L. huidobrensis group of species by this assay. The effect of parasitism on L. huidobrensis by Dacnusa sibirica was investigated and shown unlikely to cause misidentification of the leaf miner host. Results obtained from practical use of the assay to identify unknown specimens from ports and nurseries are compared with those obtained from flies kept in laboratory culture and used during development of the assay. No new variation was found for G6PDH. New PEP variation was found for both L. huidobrensis and L. bryoniae but this did not affect the integrity of the assay. A biochemical key to these agromyzid leaf miners is presented.  相似文献

Six new Diplopeltula species are described: D. pulchra sp.n., D. belgica sp.n., D. striolata sp.n. and D. curta sp.n. (Southern Bight of the North Sea), D. nellyae sp.n. and S. pumila sp.n. (New Caledonia). Diplopeltula indica Gerlach, 1962 is redescribed from Guadeloupe (FWI). Based on the examination of these seven Diplopeltula species, the genus has been reappraised. The systematic position of the other genera of the Diplopeltidae Filipjev, 1918 is also discussed. Diplopeltoides Gerlach, 1962 is moved from the Aegialoalaimidae Lorenzen, 1981 to the Diplopeltidae.  相似文献

Eight species of the genus Macrosiphum Passerini 1860 (Sternorrhyncha: Aphididae) are recognized from the Korean Peninsula. A new species, Macrosiphum ( Macrosiphum ) paektusani n. sp., is described herein for apterous and alate viviparous females on Rosa marretii Lev. (Rosaceae). The taxonomic position of Macrosiphum ( Macrosiphum ) cornifoliae Shinji 1924, com. rev., is transferred from the genus Sitobion Mordvilko 1914 to its original position. Host plants of the Korean Macrosiphum are reviewed and the identification key to subgenera and species is also presented.  相似文献

In the western Atlantic Ocean, the brown algal genus Lobophora is currently represented by a single species, L. variegata, with a type locality designated by Lamouroux as ‘Antilles’. In this study, we used molecular-assisted alpha taxonomy (MAAT) to assess species diversity of Lobophora in Bermuda, the Florida Keys, St. Croix and Guadeloupe (Lesser Antilles). Using cox1 and cox3 sequences as barcode markers, five species of Lobophora, four of them novel, were delineated, all previously having been identified in the area as L. variegata. Our morphological and habitat studies, made possible by abundant sampling, have revealed unique characters for each of these western Atlantic species, including distinct cellular arrangements, as well as different depth ranges for certain species. Observations made from Lamouroux’s holotype of Dictyota variegata (= Lobophora variegata) allowed us to assess the anatomy of this species, which enabled us to easily align this early taxon to one of our genetic species from the western Atlantic. As the type was unavailable for genetic analysis, we selected a recent St. Croix (Virgin Is., Antilles) specimen as the epitype to support it with molecular sequence data.  相似文献

The skulls of 387 shrews of the genus Crocidura sampled in peninsular Malaysia, Sumatra, Borneo, Java and Sulawesi were submitted to principal component and stepwise discriminant analyses. These analyses helped to delineate morphological taxa in this species-rich genus of mammals. Most morphologic groups could be attributed to described species, except one taxon from Sumatra and one from Sulawesi, which are described and named as new. Most of the 21 species recognized in this paper are endemic to one major island. Although Sulawesi has never been connected to the mainland, it supports at least six species, followed by Sumatra (5–6 species), Java and the Malay Peninsula (4 spp) and Borneo (3 spp). C. monticola is apparently the only widespread species whose distribution range covers the entire Malay Archipelago except the Philippines and Sulawesi. In contrast, the continental C. fuliginosa enters only marginally into the Sunda Shelf: its southernmost record is on the Malay Peninsula. This interpretation is completely different from the classical view that C. fuliginosa is a cosmopolitan species occupying the whole of Southeast Asia. Identification keys, tables of measurements and discriminant functions provided in this work may aid in identification of the various species and subspecies of Crocidura living in the Malaya Archipelago.  相似文献

The ovarian cycle was studied in two species ofTrichogramma, the thelytokousT. cacoeciae and the arrhenotokousT. brassicae. For both species, egg development was recorded (1) in the immature stages (2) in adult females before and after one bout of oviposition. The two species differed in the numbers of immature eggs formed and stored in the ovaries, and in the pattern of egg replenishment after oviposition.  相似文献

The taxonomic status of the red algal genus Pachymeniopsis (Halymeniaceae) was evaluated based on a morphological study of the type species Pachymeniopsis lanceolata (Okamura) Yamada in Kawabata (=Aeodes lanceolata Okamura). Features used to separate Pachymeniopsis from allied genera such as Aeodes or Grateloupia were found to be inconsistently expressed within even single populations, and P. lanceolata is considered to be best placed in Grateloupia. The two remaining species, P. yendoi and P. elliptica, are judged to be conspecific, with P. elliptica also best placed in Grateloupia. The genus Pachymeniopsis is, therefore, considered synonymous with Grateloupia. The transfer of P. lanceolata to Grateloupia is proposed as Grateloupia lanceolata (Okamura) Kawaguchi, comb. nov. The reinstatement of Grateloupia elliptica Holmes, which includes Pachymeniopsis yendoi as a synonym, is also proposed.  相似文献
