TWO NEW SPECIES OF MICROGASTER LATREILLE (HYMENOPTERA: BRACONIDAE) FROM CHINA*

Abstract The present paper describes two new species of Microgaster Latreille, 1804, viz: M. longiterebra sp. nov. (♂) and M. longicaudatus sp. nov. (♂).

M. longicaudatus sp. nov. is described from Tianmushan, Zhejiang Prov. in China closely related to M. ductilis, but differs from the latter in the combination of the following features: 1) middle and hind femora reddish yellow only with apical 1/4 blackish; 2) 1‐SR 0.5 times as long as 1‐M; 3) the hairy part of ovipositor sheath 0.5 times as long as hind tibia; 4) tergite 3 with slightly weaker rugosity. The type specimens are deposited in Zhejiang University, Hangzhou, China.

New fossil evidence of the early diversification of scarabs: Alloioscarabaeus cheni (Coleoptera: Scarabaeoidea) from the Middle Jurassic of Inner Mongolia,China

Abstract Scarabaeoidea are known from the Lower Jurassic and may have originated in the Triassic based on fossil evidence and phylogenetic research. However, the early diversification of Scarabaeoidea remains unclear due to the lack of high‐quality fossil evidence. Here we describe an exceptionally well‐preserved new fossil of Scarabaeoidea, Alloioscarabaeus cheni gen. et sp. nov from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, China. Based on a morphometric analysis using 17 landmarks of the hind wing of Alloioscarabaeus and 10 scarabaeoid families, we found that Alloioscarabaeus cheni gen. et sp. nov clearly does not belong to any of the known scarabaeoid families and, consequently, is a new family, Alloioscarabaeidae fam. nov., was erected. The discovery of Alloioscarabaeus brought further evidence for the early diversification of major scarab lineages which could allow more detail in the palaeobiogeography of the Scarabaeoidea and Northeast of China which might be one of the originating places or an important radiation place during the evolution of Scarabaeoidea. Alloioscarabaeidae were very likely not good diggers and might have fed on decaying organic materials. Based on the evidence we have now, we tend to believe that most families and some subfamilies of Scarabaeoidea were present in the Jurassic period.

Molecular phylogenetic analysis of the Amiota apodemata and Amiota sinuata species groups (Diptera: Drosophilidae), with descriptions of four new species

The phylogenetic relationships among the East Asian species of the apodemata and sinuata species groups of the genus Amiota were investigated based on DNA sequences of the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene. A total of 23 samples of 12 species were employed as in‐group taxa, and one sample for each of four other Amiota species were used as out‐groups. The results suggested with strong confidence the monophyly of both the apodemata and the sinuata groups, whereas the monophyly of the ‘apodemata group + sinuata group’ cluster was less supported. Based on its geographical distribution, the origin of the sinuata group is supposed to be southern China. Four new species were described from Guangxi and Yunnan, China: Amiota reikae Xu & Chen sp. nov. , Amiota guiensis Xu & Chen sp. nov. , Amiota hesongensis Xu & Chen sp. nov. , and Amiota polytreta Xu & Chen sp. nov. © 2013 The Linnean Society of London
