3.2. NEPTICULIDAE OF CENTRAL ASIA – A REVIEW OF THE FAUNA
In Central Asia, 90 nepticulid species were recognized; most of them (54
species) belong to Stigmella, 16 to Acalyptris, 11 to Ectoedemia, 4 to Fomoria, 2 to
Glaucolepis, 2 to Etainia and 1 to Trifurcula. Fifteen species were described by the
author as new to science (Table 2).
Western Kopetdag and the southern slopes of the Gissar Ridge are recognized
as the areas in the region most diverse in nepticulid species. However, about onethird
of the Kopetdag fauna is represented by species with a Euro-Asian
distribution, in contrast to the Gissar nepticulid fauna which characterized by
93% of endemic species. In total, the endemism of the Central Asiatic Nepticulidae
fauna is very high (71%) (figs 9, 10).
A review of published data on nepticulid bionomics, heavily modified updated
with the author’s original larval-rearing data, shows that about half (53%) the
Central Asiatic species with a known host-plant are trophically associated with
Rosaceae (Aflatunia, Cerasus, Crataegus, Malus, Prunus, Pyrus, Rosa, Rubus, Spiraea)
(fig. 11); 11% occur on Salicaceae (Populus, Salix), 8% on Ulmaceae (Celtis, Ulmus),
Aceraceae (Acer) or Rhamnaceae (Paliurus, Rhamnus, Ziziphus), and 6% on
Betulaceae (Betula). Plant families such as Hypericaceae, Moraceae and Fagaceae
are known as host-plant families for just a single nepticulid species.
