摘要:

TheProtonemura corsicanaspecies group shows an interesting Circummediterranean‐Caucasian distribution, with several relict or insular species. Eight populations belonging to four species of this group and six populations belonging toIsoperla insularis(Morton) were studied by means of electrophoresis, performed on horizontal starch‐gel. Samples were screened for variation at 17 presumptive loci and genetic divergence was calculated. Phenetic treating of allozymic data does not seem to support the theory of a Miocenic colonization of the Mediterranean basin. On the contrary the cladistic approach is not congruent with the phenetic methods and could be in agreement with a Miocenic vicariance hypothesis. Biogeographical patterns based on the systematic arrangement obtained are discussed. The validity of electrophoretic methods in revealing species relationships and boundaries is discussed.

摘要:

Helicopsyche siamasp.n. is described and figured. The species has a general resemblance to otherHelicopsychespecies known from Asia, especially toH. maculataMosely, 1939 known from India and Burma. In addition, the CeyloneseCeylanopsyche asaka(Mosely, 1939) (Sericostomatidae) has certain affinities withH. siamasp.n.

摘要:

The male and female imagines ofUsambaromyia nigralagen. n., sp. n. are described from the West Usambara Mountains in Tanzania. The species differs from other known chironomids by having nearly completely black wings in both sexes, tibial spurs with lateral denticles making them Tanypodinae—like, dense cluster of scalpellate sensilla chaetica on anepisternum I, male gonostylus without megaseta, laterosternite fused with tergite IX forming a single annulus and female genitalia apparently with only one seminal capsule and spermathecal duct, well developed gonocoxite IX and setae on segment X.

摘要:

The male ofAxonopsis (Paraxonopsis) danteisp. n. is described from material collected in the interstitial habitat of a small stony stream near Florence (Italy). The subgenusParaxonopsisMotas and Tanasachi is reported for the first time from Italy. A comparison was made with the other European species of the same subgenus (A.vietsiMotas and Tanasachi, 1947). Some observations on the distribution of the genusAxonopsisPiersig in Europe are also made.

摘要:

The larvae and egg case ofPhaenonotum (Hydroglobus) puncticolleBruch, 1915 are described, based on material collected in the field and reared in the laboratory. Behavioral and populational data are included and discussed. The larvae and egg cases are compared to those ofPhaenonotum (Phaenonotum) exstriatum(Say, 1835).
