The Aphelocheirid Bugs of China (Heteroptera: Aphelocheiridae)

A total of 14 species of genus Aphelocheirus Westw. from China are listed in this paper. One new species, Aphelocheirus brunneus sp. n., is described from Hubei Province. Aphelocheirus carinatus (Royer, 1920) is reported from China for the first time. The type specimens are deposited in the Department of Biology, Nankai University, Tianjin (300071), China.     

Life cycle of three stonefly species (Plecoptera) from an Apenninic stream (Italy) with the description of the nymph of Nemoura hesperiae

The life cycles of Isoperla grammatica, Amphinemura sulcicollis and Nemoura hesperiae are studied in a Northern Italy stream, sited in the Apennines. The three species show a univoltine life cycle and their development coincides approximately in the same period of the year, although the one of I. grammatica is longer. Possible egg dormancy could exist in the A. sulcicollis and N. hesperiae life cycles, but this needs to be proved. The three taxa show a spring flight period in the study area. Growth is almost constant through the life cycle, except in A. sulcicollis in which an increase is observed at the end of the development. N. hesperiae exhibits a faster growth than the other species. In addition, in this paper, the nymph of N. hesperiae is described and designed for the first time.

Nymphal trophic behaviour of two Nemouridae species (Insecta,Plecoptera) in the Curone creek (northern Apennines,Italy)

Feeding habits of the Euholognathan stoneflies Nemoura hesperiae and Amphinemura sulcicollis are studied in a little stream located in northern Italy. The former fed mainly on coarse particulate organic matter (CPOM), together with detritus, while the latter fed principally on detritus and, in a lower concern, on CPOM. Thus they can be catalogued fundamentally as shredder and collector‐gatherer, respectively. Shifts in diet composition were detected in relation to size in both taxa. Probably niche overlapping does not exist despite both species having similar size and nymphal development duration, and coinciding in time. This work supports that, though functional feeding groups are very useful, they should not be inferred from related species or higher taxonomical levels. Even intra‐population differences and ontogenetic shifts should be considered in fine scale studies.     

THREE NEW SPECIES OF AMPHINEMURA (PLECOPTERA: NEMOURIDAE) FROM TIBET, CHNA

Abstract Three new species from Tibet are described: Amphinemura yangi, A. lii and A. tibetensis. Their relationships with the relative species are discussed. A key to the species of the genus Amphinemura from Tibet is presented. The types are deposited in the Insect Collection of China Agricultural University.
