Nearctic Region

In the Nearctic region the genus Eugnoriste includes 7 species currently. Four of them are new to science. These are Eugnoriste brachycostalis sp. n., Eug. florea sp. n., Eug. hirsuta sp. n. and Eug. ptilosis sp. n. The male of Eug. brevirostris Coquillett, which has been unknown until now, was identified and described herein. Moreover, an additional description and figures were given for Eug. occidentalis Coquillett. Eugnoriste villosoabdominalis Mohrig is reported as new for North America. The genus Keilbachia includes three species in the Nearctic region presently. Two of them are new to science. These are Keilbachia americana sp. n. and K. semiacuta sp. n.        All species presented here were diagnosed, keyed and illustrated by figures as well as data of their distribution provided.

Nearctic Region

In the Nearctic region the genus Pseudolycoriella currently includes 13 species. The following seven species are new to science: Psl. basisetosa sp. n., Psl. brevialata sp. n., Psl. chlorothoracica sp. n., Psl. flavipila sp. n., Psl. longisetosa sp. n., Psl. nocturna sp. n. and Psl. subjucunda sp. n. All species are keyed, figured and distribution data is given. Ostroverkhovana Komarova, 2002 is regarded as a junior synonym of Pseudolycoriella Menzel & Mohrig, 1998. Phytosciara (Prosc.) plusiochaeta (Hippa & Vilkamaa, 1991) is reported from North America for the first time.

Seven species of the genus Camptochaeta, two of the genus Claustropyga and one of the genus Dichopygina are newly described from the Nearctic region. These are: Camptochaeta abnormalis sp. n., Cam. camptochaetosa sp. n., Cam. grimaldii sp. n., Cam. multispina sp. n., Cam. praexystica sp. n., Cam. subxystica sp. n., Cam. unispina sp. n., Claustropyga postbrevichaeta sp. n., Cl. subbrevichaeta sp. n. and Dichopygina praeaculeata sp. n. All new species are diagnosed and their distribution data are given. Three species, Camptochaeta duplicata Hippa & Vilkamaa, 1994, Claustropyga abblanda (Freeman, 1983) and Cl. sajanica (Mohrig & Antonova, 1978) are reported for the Nearctic region for the first time. With these new species, Camptochaeta includes 30 species, Claustropyga 15 species and Dichopygina 6 species in the Nearctic region now.

Abstract A description is provided for Coniothyrium minitans. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Sclerotinia sclerotiorum, S. trifoliorum and, under laboratory conditions, can attack sclerotia of Botrytis cinerea, B. fabae, B. narcissicola, Sclerotinia minor and Sclerotium cepivorum. DISEASE: Hyperparasite of sclerotia of phytopathogenic fungi such as Sclerotinia sclerotiorum and S. trifoliorum (55, 4614, 4972). GEOGRAPHICAL DISTRIBUTION: Australasia & Oceania (Australia, New Zealand); Europe (Britain, Finland, East Germany, Hungary, Poland); North America (Canada, USA). TRANSMISSION: By conidia and mycelia dispersed in the soil from disintegrating infected sclerotia which are covered with numerous pycnidia releasing abundant conidia. It has also been suggested that disintegrating infected sclerotia could be dispersed with the mycoparasite by fungus gnats (Mycetophilidiae) (Turner & Tribe, 1976).

Dispersal Events

Two new species of fungus gnats (Diptera: Mycetophilidae), Azana malinamoena and Azana frizzelli, spp. nov., are described and figured from California. These species represent the first records of Azana for western North America. A diagnosis of the genus Azana Walker is presented and a provisional key for the New World species of the genus is given. The discovery of A. malinamoena and A. frizzelli in California and their apparently close relationship to A. nigricoxa Strobl from south-western Europe (rather than to the only other Azana species known from North America, A. sinusa Coher) implies a more complicated biogeographic history of this genus in North America, one that probably includes multiple, independent dispersal events.
