4. A GLOBAL REVIEW OF THE NEPTICULOIDEA AND TISCHERIOIDEA AND CATALOGUE OF THE WORLD FAUNA After revision of all published records (including the author’s personal research data), 1027 species of Nepticuloidea & Tischerioidea are currently recognized for the world fauna. Most of them, 780 species, belong to the Nepticulidae, 130 to the Opostegidae 117 to the Tischeriidae. These species are included in the first catalogue of the world Nepticuloidea & Tischerioidea, together with revised data on species distribution and host-plants (see Supplements of the dissertation or the published version in Diðkus, Puplesis, 2003). A few new species-groups are designated in the catalogue. Also 126 new combinations are made and a few species previously omitted from taxonomic revisions by other authors (dealing with Africa or other regions) are listed. It is estimated that 124 authors described nepticuloids and tischerioids. Peaks of species description occurred in 1911–1915, 1976–1980 and particularly in 1984– 1985 and 2000. The author of this dissertation described (on his own or with co-authors) 44 new species of Nepticulidae and 36 species of Tischeriidae (figs 1, 2). 28 Australian 7% Oriental 9% Afrotropical 15% Palaearctic 44% Nearctic 14% Neotropical 11% Fig. 13. Currently known number of species of Nepticuloidea and Tischerioidea and biogeographical regions Most Nepticuloidea and Tischerioidea (445 species or about 44%) are known from the Palaearctic (fig. 13). In the Nepticulidae, only the genera Stigmella and Fomoria can be recognized as having truly cosmopolitan distributions. Acalyptris, in contrary to previous knowledge, appears also to be widely distributed and unexpectedly occurs in rain forest habitats. During this study an interesting feature of Acalyptris distribution was discovered: in the Neotropical region the genus predominates, accounting for up to 50% of the nepticulid fauna of the tropical areas of the region. Otherwise, Stigmella is the dominant nepticulid genus in most geographical regions and in non-tropical areas of the Neotropical region.
Despite very high species endemism, endemism at generic level varies from region to region: in the Palaearctic and Afrotropical regions endemic taxa make up 20% of the fauna, in the Neotropics 17%, in Australia about 50%. North & South America are supposed to be the centre of highest diversity of the Tischeriidae and, possibly, their centre of origin. The Neotropical region is remarkable in the taxonomic composition of its Tischeriidae: as well as Coptotriche and Tischeria (genera which occur in almost every biogeographical region), there is the third genus – Astrotischeria – which comprises 74% of the currently known species of the area (fig. 14). 58% 62% Coptotriche (3) 13% Coptotriche (14) Coptotriche (28) Palaearctic Region Nearctic Region Tischeria (10) Fig. 14.
