Abstract

Species Diversity and Distribution of Scorpionfly in Thailand aims to study species and distribution, relationships between species, climatic factors and study taxonomic characteristics of Mecoptera in 29 sampling points in national parks and wildlife sanctuaries. The study was conducted by randomly placing Malaise traps and pan traps. A total of 797 specimens were classified to 21 species in 4 genera and 2 families, 2 species of the Bittacidae family, including Bittacus leptocaudus and Terrobittacus sp., 19 species of the Panorpidae family, including Neopanorpa angustipennis, N. appendicema, N. arcuata, N. byersi, N. cuspidata, N. harmandi, N. inchoata, N. infuscata, N. latiseparata, N. malaisei, N. nielseni, N. normpennyi, N. pendulifera, N. setosiloba, N. siamensis, N. spatulata, N. thai, N. tuberosa and Panorpa apscisacera. The most abundance species was N. harmandi (27.48%), followed by N. siamensis (11.29%), N. byersi (10.29%), N. malaisei (8.78%) and N. spatulata (7.28%) respectively. In this study, N. cuspidata was found as a doubleton species, while N. latiseparata was as a singleton species. Moreover, Terrobittacus sp. was discovered for the first time in Thailand. The abundance and species richness peaks at altitudes of 501 - 1000 meters above sea level also in rainy season, the 50% of total specimens was collected and 66.67% of species in all altitudes were found, N. harmandi is the predominant species. Pha Tang Substation (A8) in Doi Chiang Dao Wildlife Sanctuary is the sampling point with the highest abundance representing 10.54% of the total specimens, N. spatulata was the predominant species. Doi Phaluang (A2) in Doi Pha Hom Pok National Park is the sampling point with the highest species richness accounting for 33.33% of all species were found, N. arcuata is the predominant species.
