Review of Strongylogaster Dahlbom (Hymenoptera: Tenthredinidae) from Zhejiang Province, China, with the description of a new species

ABSTRACT Five species of Strongylogaster Dahlbom, 1835 are recorded from Zhejiang Province, China. They are four known species, S. formosana (Rohwer, 1916), S. macula (Klug, 1817), S. takeuchii Naito, 1980 and S. xanthocera (Stephens, 1835), and a new species. Strongylogaster tianmunica sp. nov., collected from Mt. Tianmu in Zhejiang Province, is here described and illustrated. This new species resembles S. nantouensis Naito, 1990, but differs from the latter by the following characters: female body length 10-12 mm, male body length 8-10 mm; tegula brown to dark brown; pronotum largely yellowish-white; trochanters black, apical half of hind femora and of hind tibiae yellowish-white; malar space as long as radius of median ocellus; antennomere 3 as long as antennomere 4; and ovipositor apical sheath with distinct lateral scapes. A key to the five species of Strongylogaster from Zhejiang Province is provided.</div

Review of the Pachyprotasis flavipes group (Hymenoptera: Tenthredinidae) from China with descriptions of two new species

ABSTRACT The flavipes group of Pachyprotasis Hartig, 1837, with twenty-four species recognized in China, is reviewed. This number includes two newly described species, Pachyprotasis rufodorsata sp. nov., from Sichuan, Hubei, Ningxia, and Shaanxi provinces, and Pachyprotasis nigritarsalia sp. nov., from Hunan province. The mesopleuron and metapleuron of the two new species are reddish-brown, distinguishing them from other similar species of the P. flavipes group. Thirty-four species of this group have been recorded from China, one species (P. variegate Fallén, 1808) was found to be widespread throughout Europe and Siberia, twenty-four were originally described from the China and Burma-Yunnan frontier, eleven from India, and five from Japan. A key to the species of this group from China is provided.</div

The complete mitochondrial genome sequence of <i>Pachycephus smyrnensis</i> Stein, 1876 (Hymenoptera: Cephidae) with phylogenetic analysis

The complete mitochondrial genome of Pachycephus smyrnensis Stein, 1876 collected from Sivas, Turkey, is described. The circled genome is 20,393 bp in length and contains a typical set of 37 genes. The missing control regions, trnQ and trnI in previously reported P. smyrnensis (KX907846) were obtained in this precise assembly based on a considerable amount of raw data. A denser sampled phylogenetic analysis shows that the two P. smyrnensis constitute a branch sister to P. cruentatus (Eversmann, 1847). Pachycephus is a sister group of Phylloecus within Hartigiinae and remote from Characopygus, a genus within Cephinae. The monophyly of Pachycephini has been rejected.</p
