Materials of Lathrobiina (Coleoptera,Staphylinidae) from Shanghai,eastern China,were examined.Three species were identified:Lathrobium dignumSharp,1874,Pseudolathra lineataHerman,2003 andTetartopeus gracilentusKraatz,1859.Lathrobium dignumandTetartopeus gracilentusare newly discovered from Shanghai.Illustrations of female sexual characters ofLathrobium dignumandPseudolathra lineataare provided for the first time.

1 Introduction

The speciose paederine Subtribe Lathrobiina is represented in China by 318 species in ten genera[1-7].Only one species of the genusPseudolathraCasey,1905 was previously recorded from Shanghai:Pseudolathra lineataHerman,2003[7],but no species of the genusLathrobiumGravenhorst,1802 andTetartopeusCzwalina,1888 have been reported from Shanghai.

We surveyed the staphylinid fauna of several localities in Shanghai (Shanghai Zoo,31°11’N,121°21’E;Shanghai Normal University,31°09’N,121°24’E;Songjiang,31°02’N,121°13’E;Taigu,31°11’N,121°23’E and Tianma Hill,31°04’N,121°09’E),and collected numerous specimens.During the study on the Chinese Lathrobiina,Lathrobium dignumSharp,1874 andTetartopeus gracilentusKraatz,1859 were newly collected from Shanghai,eastern China.In this paper,we would like to provide illustrations of its habitus and female sexual characters ofLathrobium dignumSharp,1874 andPseudolathra lineataHerman,2003.The treated specimens are deposited in the Insect Collections of Shanghai Normal University,Shanghai,P.R.China (SHNU).

2 Materials and methods

All specimens were collected from the forest floor by sifting.They were killed with ethylacetate and then dried.Dissections were done in water.The genital organs and other dissected parts were mounted in Euparal (Chroma Gesellschaft Schmidt,Koengen,Germany) on plastic slides that were placed on the same pin as the specimen.Photos were taken by a Canon EOS 40D Camera with an MP-E 65 mm Macro Lens or by a Canon G9 Camera mounted on an Olympus CX31 microscope.

Comment.The female sexual characters are as follows:posterior margin of tergite VIII (Fig.2(a)) weakly convex;posterior margin of sternite VIII (Fig.2(b)) convex;female tergite IX (Fig.2(c)) with very long antero-median portion and slender postero-lateral processes,antero-median portion without median suture;tergite X (Fig.2(c)) 0.5 times as long as antero-median portion of tergite IX.For illustrations ofL.dignumsee Cho (2012:figures 5,12,13)[8].

Distribution andbiological notes.Lathrobium dignumwas previously recorded from Russia,North Korea,South Korea,Japan and the Chinese provinces Jiangsu,Gansu and Shaanxi[9].This species is newly discovered from Shanghai.Some of specimens were collected by sifting bamboo leaves and humus from the floor of a bamboo forest in the arboretum of the Shanghai Normal University (Fig.3).

Distribution and biological notes.Previously,this species was known from Japan,the Chinese provinces Jiangsu,Jiangxi,Shanghai,Sichuan and Taiwan[9].The specimens were collected by sifting leaf litter and weeds from the floor of the hardwood forest withCinnamomum camphora,Platanus acerifolia,Fatsia japonica,Celtis sinensis,Trachycarpus fortuneiandMorus albain the Shanghai Zoo (Fig.4).
