The present study provides faunistic information obtained from the study of a collection of the sphaerocerid flies (Diptera, Sphaeroceridae) in Liaoning and Jilin, Northeast China. A total of 1720 specimens, belonging to 3 subfamilies (Copromyzinae, Sphaerocerinae, Limosininae), were examined and 62 species were identified in our sample. Among the identified species one genus and 16 species are newly recorded in China:Crumomyiagelida(Hackman, 1965);Ischioleptapusilla(Fallén, 1820);AptilotuslonginervisHayashi, 1989;Chaetopodellascutellaris(Haliday, 1836);Leptoceracaenosa(Rondani, 1880);L.vomerataRohek & Papp, 1983;Minilimosina(Svarciella)guestphalica(Duda, 1918);M.

0 Introduction

Studies on morphological taxonomy of the Sphaeroceridae have been conducted for several years in China, but despite this, Chinese species of Sphaeroceridae are still poorly known. The fundamental objectives of the present study are to provide a comprehensive checklist of Sphaeroceridae in Liaoning and Jilin, to develop a database to be used for identification purposes, and to expand upon existing information about the sphaerocerid fauna of China. During the course of this work, 62 species from 21 genera were identified, including 16 newly recorded species in China. Additionally, several uncommon species were found in our sample, particularly in the genusAptilotus. This study therefore contributes a significant advance in knowledge of the Sphaeroceridae in China. Finally, a syn. nov., namelyLeptoceraspinisquamaSu, 2011 is treated below.

This study of sphaerocerid diversity in Northeast China contributes not only to a better understanding of the species richness of Sphaeroceridae in China, but also to providing valuable precision regarding the hitherto poorly known distribution of some uncommon species.

1 Material and methods

The present study of species of Sphaeroceridae in Liaoning and Jilin is based on all relevant published records and supplemented by data obtained from the materials collected recently in Liaoning and Jilin. The specimens of Sphaeroceridae were identified by the authors and deposited in Liaoning Key Laboratory of Urban Integrated Pest Management and Ecological Security, Shenyang University, China (LKLSU).

For each capture, a valid species name, the original published name of the species, all subsequent generic and subgeneric combinations cited by Chinese dipterists, the Chinese geographic distribution information, and any comments are presented.

2 Results

A total of 1720 adult sphaerocerid specimens were collected in Liaoning and Jilin, Northeast China, and belonging to 3 subfamilies, were subsequently examined. Their identification resulted in a number of interesting new records, some of which are already published in Su and Liu (2009a, 2009b, 2009c), Su (2011) and Suetal. (2009, 2013a, 2013b, 2013c, 2013d, 2013, 2015, 2017). In the present paper, 3 subfamilies, 21 genera and 62 identified species are listed below.

3 Discussion and conclusions

Until now, the Sphaeroceridae of Northeast China fauna has not been systematically studied, particularly lacking a comprehensive understanding of the qualitative species composition, biology, and accurate distribution information of Northeast China fauna. The present study firstly provides the checklist of Sphaeroceridae of Liaoning and Jilin in Northeast China, 62 species (1270 specimens) were recorded. Among them, 32% (20 species) are quite common species broadly distributed around the world

It should be stressed that in the remaining 42 species, 44% (27 species) are only recorded in the Palaearctic Region, of these latter species, 4 species (LeptoceradyscolaRohek & Papp, 1983;L.vomerataRohek & Papp, 1983;Opacifronselbergi(Papp, 1979);Rachispodaexcavata(Papp, 1979)) that had previously been only reported in Russia (Roheketal. 2001, Marshalletal. 2011); and 6 species (AptilotuslonginervisHayashi, 1989;ParalimosinaprominensHayashi, 1985;Pullimosina(Pullimosina)vernalisHayashi, 2006;TerrilimosinabrevipexaMarshall, 1987;T.paralongipexaHayashi, 1992;T.nanaHayashi, 1992) that had previously only been reported in Japan (Roheketal. 2001), are, with this study, newly added to the known fauna of Northeast China in the Palaearctic Region. The similar species composition between Northeast China and Japan or Russia is consistent with a general phenomenon wherein the fauna of Northeast China are similar to, and closely related to, Japanese fauna and Russian Far East fauna. The others (15 species) are relatively narrowly distributed in the world. 11% (7 species) are only recorded in the Holarctic Region; 13% (8 species) only recorded in the Oriental and Palaearctic Regions.

The shortcoming of the present study is no complete survey of the whole territory of Northeast China region. But the study reflects the basic fauna, species composition and biological characters of Sphaeroceridae in Liaoning and Jilin. Considering that the area of Northeast China is vast, with complex and diverse habitats, intensive research on Sphaeroceridae of Northeast China is urgently needed.
