Female imagines, subimagines, eggs and larvae of Electrogena antalyensis (Kazanci & Braasch) from Turkey are described for the first time. The results of a thorough analysis of larvae, based on the standard set of diagnostic characters for the identification of Electrogena species, are reported. The peculiarity of several characters places E. antalyensis in an isolated position within the genus Electrogena. 相似文献

The genus Hemibidessus Zimmermann, 1921 is revised. Six species are recognized in the genus. Two new species are described, H. spirodiscus sp. n. from Bolivia and H. spangleri sp. n. from Argentina. A key for identifying the species is presented. The female genitalia are thoroughly illustrated and described for the first time for any species of Bidessini. Other important diagnostic structures are also illustrated including the male genitalia. A cladistic analysis is presented for 8 species (6 ingroup and 2 outgroup species) and 13 characters. A single most parsimonious cladogram was found. 相似文献

Two new species of Lacconectus Motschulsky are described from Vietnam, Lacconectus valeriae sp. n. and L. baolocensis sp. n., and a key is given for the species described from and occurring in that country. Together with the two new species, seven species are now known from Vietnam, and the number of Lacconectus species rises to 60. 相似文献

In this study, we present data on life history, distribution and coexistence among five backswimmer species, Notonecta glauca, N. lutea, N. maculata, N. obliqua and N. reuteri, from 72 waters in a study area on the Swedish west coast. Two temporal life history patterns were found; species reproducing in the autumn (N. reuteri and N. lutea) and those reproducing in the spring (N. glauca N. obliqua and N. maculata). Female backswimmers were generally larger than conspecific males, except for N. lutea, in which the sexes were similar in size. The sex ratio of N. glauca, N. lutea and N. reuteri did not differ from 1/1. The most abundant species was N. glauca (49% of the waters inhabited by backswimmers) and then N. obliqua (19%), N. maculata (14%), N. lutea (10%) and N. reuteri (8%). In all, 972 individuals were recorded. The species were sequenced, with reference to their habitat use (from species occurring in temporal habitats to more stable and complex ones), as follows; N. maculata – N. glauca – N. obliqua – N. reuteri – N. lutea. N. glauca had the widest habitat distribution pattern. Two species combinations in pools were most commonly found and the five species were never found together. Possible competition among adults, according to their habitat distribution, may occur for: N. glauca with all species; N. obliqua mainly with N. glauca; N. lutea mainly with N. reuteri; N. reuteri mainly with N. lutea and N. glauca; N. maculata mainly with N. glauca. If body size is an important factor in the competitive ability between individuals, not merely species but also sex and temporal aspects have to be considered. The most intense competition should then exist between N. lutea and N. reuteri females. 相似文献

Mature larvae and pupae of Metachorema griseum Schmid are described for the first time. The known distribution of the genus includes the province of Neuquén in Argentina and central and southern Chile. The distinctive characters of the larvae of this genus are: (1) prothoracic sternite consisting of a wide subrectangular central sclerite and a pair of elongated lateral sclerites, (2) anterior femora with a narrow basodistal process, (3) anterior tibia and tarsus fused and (4) anal prolegs with a short lateral sclerite with basal spine and claws simple with ventral spine and two ventral setae. 相似文献

The first account of the predaceous diving beetles or Dytiscidae of Jordan is presented. Altogether 25 species are listed, although the occurrence of two of them remains doubtful. Nine species are recorded from the territory of Jordan for the first time, and the first precise locality data are provided for an additional seven species. Bidessus anatolicus Wewalka, 1972 and Nebrioporus stearinus (Kolenati, 1845) recorded recently from Jordan based on misidentification are removed from the list. If available, habitat information is provided for recently collected species. The zoogeographical patterns of the region are briefly summarised. 相似文献

Nonlethal DNA sampling is a highly recommendable method in molecular genetic studies of protected and endangered species. To develop a demonstrably nonlethal method of obtaining DNA from larvae of endangered diving beetles (Cybister brevis, C. lewisianus, C. limbatus, C. rugosus, Dytiscus sharpi sharpi and D. sharpi validus), we obtained the larval exuvia (molted skin) of these endangered diving beetles under laboratory conditions. A single exuvia 24 h after molting was sufficient to allow polymerase chain reaction (PCR) detection of a mitochondrial DNA gene, cytochrome‐c oxidase subunit I (COI), and the sequence of the COI gene could be determined directly. Sequences obtained from the exuvial samples were used to further find similarities within DDBJ/EMBL/GenBank. Genomic DNA from the samples was successfully isolated, and we identified the species. This process suggests that exuvia provides a good sample for extracting DNA from endangered diving beetle larvae without killing them. 相似文献
