ABSTRACT
Three subgenera Microchelonus Szpligeti, 1908 s. str., Parachelonus Tobias, 1995 and Stylochelonus Helln, 1958 are newly recorded from China, 21 new species, viz., C. (M.) adiazetos sp. nov., C. (M.) aequus sp. nov., C. (M.) brachykeraiatus sp. nov., C. (M.) bullatus sp. nov., C. (M.) clivus sp. nov., C. (M.) crassitibialis sp. nov., C. (M.) cyclotus sp. nov., C. (M.) erugatus sp. nov., C. (M.) illatus sp. nov., C. (M.) leious sp. nov., C. (M.) linzhiensis sp. nov., C. (M.) maculovittatus sp. nov., C. (M.) melanochromus sp. nov., C. (M.) platyetrus sp. nov., C. (M.) recavus sp. nov., C. (M.) ruficorpus sp. nov., C. (M.) scirpophagae sp. nov., C. (M.) staurorhytis sp. nov., C. (P.) hirsutus sp. nov., C. (S.) acaretrus sp. nov., and C. (S.) punctulosus sp. nov. are described and illustrated. Also, eleven species are reported as new to China: C. (M.) alticinctus (Tobias, 1989), C. (M.) alveatus (Tobias, 1989), C. (M.) calcaratus (Tobias, 1989), C. (M.) flagellaris (Tobias, 1989), C. (M.) insidiatrix (Tobias, 1989), C. (M.) milkoi (Tobias, 2003), C. (M.) moskovitus (Tobias, 1997), C. (M.) semilunaris (Tobias, 2000), C. (M.) temporalis (Tobias, 1986), C. (M.) varus (Tobias, 2000) and C. (M.) zaitzevi (Tobias, 1972). Four new combinations are proposed: C. (P.) compressor (Chen & Ji, 2003) comb. nov., C. (P.) macrocorpus (Ji & Chen, 2003) comb. nov., C. (P.) polycolor (Chen & Ji, 2003) comb. nov. and C. (Baculonus) rubriventris (Tobias, 1988) comb. nov. The following new names are proposed: C. (M.) jiae nom. nov. for C. (M.) bimaculatus (Chen & Ji, 2003) and C. (M.) substernatus nom. nov. for C. (M.) tobiasi (Yuldashev, 2011). Microchelonus (Carinichelonus) cavifrons Tobias, 2000 is synonymized with C. (Ca.) tabonus Sonan, 1932. A key to the Chinese species of the subgenus Microchelonus is provided together with keys to the currently known species of the subgenera Carinichelonus, Stylochelonus and Parachelonus.

(C.) capsa Tobias, 1972, C. (C.) cesa Kocak & Kemal, 2013, C. (C.) dauricus Telenga, 1941, C. (C.) fumarius Tobias, 2000, C. (C.) pannonicus Szpligeti, 1896, C. (C.) praepusillus Tobias, 2000, C.

The subgenus Arichelonus Viereck, 1913 of genus Chelonus Panzer, 1806 is newly recorded from China and five new species belonging to three different subgenera are described and illustrated from China, i.e., Chelonus (Arichelonus) allokotosus sp. nov., Chelonus (Arichelonus) kenosetrus sp. nov., Chelonus (Megachelonus) irilaminatus sp. nov., Chelonus (Megachelonus) macrodontus sp. nov., and Chelonus (Scabrichelonus) nigrifemoratus sp. nov. Keys to the currently known species of the subgenera Arichelonus, Megachelonus and Scabrichelonus are provided.

A new subgenus of the genus Chelonus Panzer, 1806 (Braconidae: Cheloninae), Mirachelonus subgen. nov. (type species: Chelonus (Mirachelonus) miraventris sp. nov.) with deeply incurved apex of carapace, is described and illustrated from southwest China. A key to the subgenera currently recognized in Chelonus is included to facilitate future identifications.

Chelonus formosanus Sonan is an important egg-larval parasitoid of noctuid moths and a potential candidate for understanding interactions between host and parasitoid mediated by polydnavirues (PDVs). We sequenced and annotated the mitochondrial genome of C. formosanus, which is 15,466 bp in length and possesses 38 mitochondrial genes. However, unlike most animal mitochondrial genomes, it contains one extra trnF gene. There are five transfer RNA (tRNA) rearrangement events compared with the ancestral gene order, which is a novel rearrangement type in Hymenoptera for all published mitogenomes so far. Phylogenetic trees supported C. formosanus from the subfamily Cheloninae was closely related to the subfamily Cardiochilinae and Microgastrinae.
