Abstract

Babindella physoura and B. whianensis gen. et spp. n., are described from Queensland and New South Wales, respectively. Babindella is distinctivc in having a symmetrical male postabdomen with the seventh and eighth segments fused, ands is regarded as the sole representative of a new dolichopodid subfamily, the Babindellinae. The development of symmetry in the diptcran male postabdomen is discussed.

Abstract

Atlatlia, a new genus with two induded new species. A. grisea from New South Wales and A. flaviseta from Western Australia, is described. The genus is placed in the dolichopodid subfamily Medeterinac. Males have an extremely long hypopygial peduncle formed of abdominal segment seven.

Lapita Bickel (Diptera: Dolichopodidae: Sciapodinae), previously known only from New Caledonia, is newly described from Fiji and nearby Pacific archipelagoes, and includes 21 species in four species groups. The vakalevu group comprises four new species, Lapita vakalevu from Fiji and Tonga, and L. morleyi, L. savura and L. tavuki, all from Fiji. The tuimerekei group comprises two new Fijian species, L. batiqere and L. tuimerekei. The paradoxa group comprises two new species from Viti Levu, Fiji, L. paradoxa and L. maafusalatu. The denticauda group includes 13 species, L. greenwoodi (Bezzi), comb. n., from Viti Levu, L. sanma, a new species from Vanuatu (Espiritu Santo), and eleven additional new species, all from Fiji: L. adusta, L. macuata, L. coloisuva, L. delaco, L. timocii, L. bicolor, L. veilaselase, L. kuitarua, L. denticauda, L. sarnati, and L. vatudiri. Most Lapita species are known only from single or adjacent sites, suggesting a high level of local endemicity. As demonstrated elsewhere for the Sciapodinae, there is a strong connection between Fiji and Vanuatu, with species groups shared between the two archipelagoes. Biogeographical processes to account for the distribution of Lapita on Fiji and New Caledonia are discussed.

This is the first comprehensive synopsis of the biodiversity of Diptera, which with more than 150.000 described species contain more than one tenth of all described animal species. The first part is a review of what is already known, with treatments of all the major biogeographical regions and important archipelagoes; the second part contains case studies on open-ended taxa, Diptera as ecological indicators, and how to estimate the still unknown proportion of our fauna; and the third part discusses the digital and molecular tools needed to document the fauna. The book has an emphasis on principles and analytical approaches as well as on practical ‘how-to’ information and is intended for academicians and other professionals but with a significant outreach to students.

Abstract

The Dolichopodidae (Diptera) of the Galápagos Islands (Ecuador) are reviewed. The fauna comprises 17 species, which are described, illustrated, and keyed. Further, relevant New World taxa are discussed, with information on diagnostic characters, species groupings and new synonyms. Nine species are newly described: Amblypsilopus depilis, Medetera galapagensis, Paraclius desenderi, Chrysotus baerti, Asyndetus wigginsi, A. maelfaiti, A. cavagnaroi, A. mystacinus, and A. bursericola. The following synonyms are newly established: Condylostylus longicornis (Fabricius) (=C. detitaticauda Van Duzee), Chrysotus brevicornis Van Duzee (= C. brevispina Van Duzee, = C. latifacies Van Duzee, = C. mexicanus Robinson), and Asyndetus tibialis (Thomson) (= A. ridiculus Parent). The ecology and origin of the Galápagos Dolichopodidae are discussed, and the fauna is regarded as an extension of the New World mainland coastal and littoral fauna. New distributional records from North and South America are included, and the systematic relationships of Galápagos species are discussed.
