Abstract:

Objective To understand the species and other information of Calyptratae in Paomashan of Sichuan province. Methods Mist nets were used to capture the subjects in different habitats. The specimens were then classified using stereomicroscope. Specimens of significance were carefully preserved and new species were morphologically described, illustrated and published. Results A total of 123 species of Calyptratae which belong to 7 families, 18 subfamilies, 30 races and 65 genera, were described. The 123 known species from Paomashan accounted for 10.12% of all known 1 216 species of Sichuan province. Twenty-one new species and 16 indigenous species were recorded, accounting for 17.07% and 13.01% respectively of all known 123 species in Paomashan. Among 7 families, the Muscidae was the predominant genera and species, numbers of which accounted for 33.85% (22/65) and 43.90% (54/123) of known genera and species in total. On the Fauna distribution, Palearctic 71 species and oriental 45 species were recorded in Paomashan, accounting 57.72% and 36.59% of known species respectively. Others seven known species were distribution on the three type by fauna and accounting 0.81%-4.07% of known species from Paomashan respectively. Thus it can be seen that Palearctic realm species were predominant, followed by Oriental realm. Conclusion Tremendous biodiversity and indigenous Calyptratae found in Paomashan region warrant further study.
