Terrobittacus Tan and Hua, gen. nov., the third genus of the family Bittacidae from the Oriental part of China, is established with Bittacus implicatus Huang and Hua, 2006 as its type species. Terrobittacus longisetus sp. nov. and Terrobittacus xiphicus sp. nov. are described from Hunan and Guizhou, respectively. Terrobittacus implicatus (Huang and Hua, 2006) and Terrobittacus echinatus (Hua and Huang, 2008), two new combinations, are transferred from Bittacus Latreille. A key to the species of the genus Terrobittacus is provided. The biology of T. implicatus is briefly noted with descriptions and illustrations of its eggs and larvae.

The hangingfly Bittacus choui Hua et Tan, 2007 Hua, B. Z. and Tan, J. L. 2007. A new species of Bittacus Latreille (Mecoptera,Bittacidae) from Daba Mountain in China.. Acta Zootaxon Sin., 32: 455–458. [Google Scholar] is unique in Bittacidae for having only three instead of four larval instars. Its morphology was studied and illustrated in detail for developmental stages, including egg, larva and pupa. Ultrastructure of eggs, larval head, spiracles and prolegs are provided. The egg is spherical. A single micropyle was observed. The larva is eruciform with a pair of prominent compound eyes and a mid ocellus; the eight pairs of prolegs are unequal in length. Nine pairs of spiracles are located on the prothorax and the first eight abdominal segments respectively; the first instar larva differs from other instars in spiracle number. The somites are unusual, with rows of protuberances bearing distinct setiferous clavate setae. The anal segment terminates in a protrusile sucker. Pupae are exarate and decticous, taking the shape of the adults. The species completes one generation per year, overwintering as a mature larva. Adults emerge in the field from mid‐July to late August.

Dicerapanorpa gen. nov. is erected with Panorpa magna Chou as its type species. The genus is recognizable by the following characters: body yellowish with two blackish lateral longitudinal stripes on dorsum; tergum VI of males with two anal horns; abdominal segment VII of males much thinner at the basal half and abruptly thicker at apical half; parameres of males trifurcate; female genital plate with the axis not extending beyond the main plate. Six new combinations, Dicerapanorpa magna (Chou in Chou et al., 1981 Chou, I , Ran, RB and Wang, SM. 1981. Taxonomic study on the Chinese Mecoptera (I, II). Entomotaxonomia, 3(1): 1–22.

A key to the genera of Panorpidae is updated to include the new genus. A key to the species of Dicerapanorpa gen. nov. is also presented. http://www.zoobank.org/urn:lsid:zoobank.org:pub:F50E44C3-7275-4EC8-B048-4C7B2C6D57EF
