Abstract

The first Panorpa was recently discovered in Thailand even though the genus had not been thought to occur south of the Himalaya. We now add a second new species, Panorpa apscisacera n. sp., also from Northern Thailand, which has nearly immaculate pale-yellow wings with only a pronounced stigma. The male has a blunt, vestigial bifid anal horn, and thin, bare ventral parameres. Additionally, we describe Neopanorpa appendicema n. sp. with mesad-curled male hypovalve apices and large, basomesal lobes, a relatively large species, N. inchoata n. sp., with overlapping elliptical hypovalves and incomplete apical bands, N. setosiloba n. sp. with huge bristly lobes on the mesal margin of the male gonostyles, and N. mandangensis n. sp. with a narrow 3rd tergum process extending to the posterior margin of the 4th tergum. Neopanorpa nielseni Byers, 1965, previously known from northern Vietnam and southern China, has recently been discovered in northern Thailand. Bittacus leptocaudus Byers, 1965, known from a lone male has been rediscovered and locality details and photo of the habitat provided. These bring the number of species of Mecoptera occurring in Thailand to 22 (19 Neopanorpa, two Panorpa, and one Bittacus) and the number of Mecoptera species known from Indochina to 56 (48 Neopanorpa, three Panorpa, 4 Bittacus, and one Bicaubittacus). A key to the species of Mecoptera in Thailand with illustrations is provided. DNA was extracted from specimens and the DNA Barcode, mitochondrial cytochrome oxidase I (COI) gene fragment sequenced and analyzed for 19 of the 22 species of Thai Mecoptera. The results are figured as a Neighbor-Joining tree.
