| Abstract [eng] |
Winter gnats of the genus Trichocera are one of the main insect groups found in mild climates during the autumn, winter and spring months and so are unique in their way of adapting to living in colder seasons. Phylogenetic links of the genus Trichocera are examined, taxonomy of the genus renewed, species composition of several regions is ascertained and characters for dividing into subgenuses are specified in this thesis. Based on the material collected in Lithuania by standard entomological techniques and by analysis of literature data, a list of 22 species of winter gnats is given with 9 species new for our country. One new for science species of winter gnats is described from Sardinia, Italy. Based on the selected morphologic characters, phylogenetic analysis was performed and 15 species were transferred from one subgenus to another as a result. Characters of male aedeagal complex were found to be a basis for attributing the species into particular subgenus. For the first time important structures of the females of four species, male of one species and type specimens of 15 more species were illustrated. World catalogue of the 110 recent species of Trichocera is compiled and different structures of 106 species are illustrated. |
