The genus Alphitobius Stephens (Coleoptera,Tenebrionidae, Alphitobiini) in Africa and adjacent islands

All species of the genus Alphitobius Stephens, 1829 (Alphitobiini Reitter, 1917, subfamily Tenebrioninae Latreille, 1802) from Africa and adjacent islands are revised. New species: Alphitobius capitaneus sp. n. from Kenya. New synonyms: Cryptops ulomoides Solier, 1851, syn. n. of Alphitobius diaperinus (Panzer, 1796); Alphitobius rufus Ardoin, 1976, syn. n. of Alphitobius hobohmi Koch, 1953); Peltoides (Micropeltoides) crypticoides Pic, 1916, syn. n. of Peltoides (Micropeltoides) opacus (Gerstaecker, 1871), comb. n. Homonym: Alphitobius ulomoides Koch, 1953 = Alphitobius arnoldi nom. n. New combinations from Alphitobius: Ulomoides basilewskyi (Ardoin, 1969), comb. n.; Peltoides (Micropeltoides) opacus (Gerstaecker, 1871), comb. n. Figures of all examined species are added and a species key is compiled.     

New Aradidae from Ecuador (Hemiptera,Heteroptera, Aradidae)

As an addition to the presently poorly known aradid fauna of Ecuador, 3 new genera and 4 new species are described: Osellaptera setifera gen. n., sp. n.; Kormilevia ecuadoriana sp. n. both belonging to Mezirinae; and Carventinae Cotopaxicoris cruciatus gen. n., sp. n. and Onorecoris piceus gen. n., sp. n. An updated key is provided for all species of the Neotropical genus Kormilevia Usinger & Matsuda, 1959.     

The colonisation of experimental ponds by Chironomidae (Diptera)

The colonisation and succession of chironomids in a newly‐dug gravel pit habitat was investigated using replicate experimental ponds sampled during the summers of 1977 and 1978. In 1977 larvaeand emerging adults were collected, whilst in 1978 only adults were sampled. Benthic sampling showed the larval communities to be predominated by Chironomus spp. whilst trapping of adults showed that this group accounted for only 4% of the emergence. This difference is attributed to the selective retention of the larger Chironomus larvae by the sieve used to screen benthos samples. The pioneer chironomid communities in the ponds are compared using similarity and diversity indices on adult emergence data. These showed that the pond communities were remarkably uniform in 1977, the first year of their existence, due to the predominance of Tanytarsus gracilentus. In 1978 the communities were much more variable. The community structure changed within the two years, with equitability increasing rapidly to that characteristic of a much more mature habitat. These successional changes are attributed to a reduction in uniformity of the habitat resulting from the growth of aquatic macrophytes.     

Tabanidae (Diptera) of Amaz?nia XXI. Descriptions of Elephantotus gen. n. and E. tracuateuensis sp. n. (Diachlorini) from the Brazilian coast

Elephantotus, a new genus of Tabanidae from the Amazon coast, Brazil, is described based on a new species E. tracuateuensis. Five females were collected in Pará State, and a male in Maranhão State. Arguments are presented for separating the new genus from Dasybasis, as well as the possibility of its occurrence being related to the nesting sites of coastal birds. The new species is characterized by its large size (x = 2.15 cm, n = 5 females), glabrous eyes, reddish-brown tegument, light brown frontal callus not touching the edges of the eyes, extending up to the vertex that has traces of ocelli, basal plate of the antennal flagellum with obtuse angle, without a tooth or spine, wings hyaline, with brown basal cells, without appendix in the fork of vein R₄₊₅, and genital furca wide with extended flaps.     

The first record for Melittobia australica Girault in New Zealand and new host records for Melittobia (Eulophidae)

Abstract

Melittobia australica Girault is a new record for New Zealand and from Vespula spp. In the Wellington district, M. australica was found in an embryo colony of the German wasp Vespula germanica (Fabricius) and in pupae of the mason wasp Pison spinolae Shuckard in 1980 and 1981 respectively. Melittobia was recorded in nests of P. morosum Smith in Canterbury, New Zealand in 1976 and 1977. The original sources of M. australica were considered.

The validity of the earliest record of Melittobia in a social wasp host is reconsidered. It is concluded Melittobia has been underated as a parasite of social wasps.     

Locomotor Activity Patterns in Ilybius fenestratus (Fabricius) (Coleoptera,Dytiscidae) in a Central Norwegian Lake,with Evidence for Breeding-Induced Arrhythmicity

The diel activity of Ilybius fenestratus was studied in Målsj?en, a lake in S?r-Tr?ndelag, Central Norway (63°14'N, 10°26'E), during 1971–1972. Adults and larvae were sampled in activity traps every week during March–October and every 2–3 weeks during November–February. The traps were emptied every 2 hrs during a 24- hr period. The diel locomotor activity of I. fenestratus was clearly nocturnal, except in the second half of July, for the males also in the first half of July, when surprisingly the population showed an arrhythmic activity pattern. The arrhythmicity is connected with the mating and egg-laying period of the species. The larvae were also nocturnal in the autumn, but showed arrhythmicity under the ice during the winter.     

A revision of the Neotropical genus Paraberismyia Woodley (Diptera,Stratiomyidae, Beridinae) with three new species

The Neotropical genus Paraberismyia Woodley, 1995, is revised. Three new species, P. chiapas sp. n., P. mathisi sp. n., and P. triunfo sp. n. are described, all having type localities in Chiapas, Mexico. A key to the four known species is provided.
