| The subfamily Epilamprinae belongs to Epilampridae,Blattoidea,Blattodea,Insecta.There are more than 450 species around the world and about 51 species are from China.This thesis was focused on the taxonomic studies of the subfamily Epilamprinae from Shanghai Entomology Museum of the Chinese Academy of Sciences and the specimen collected by author.By reviewing literatures and examining specimens,51 known species,6 new species,1 new combination and 1 new synonym were described for morphological classification study,the keys to genera and species were given;based on the cladistics study,the cladistic trees to genera of Epilamprinae and species of Rhabdoblatta were obtained and analyzed.Through the study of biogeography,the distribution pattern of Epilamprinae was discussed.The detail results were as follows: 1.Morphological taxonomy study on Epilamprinae from ChinaThe morphological terminology was mainly based on Cockroaches of Southeastern China edited by Liu et al.(2017).Male genitalia were dissected with the stereomicroscope Leica ZOOM 2000 and was taken pictures by Moticam Pro252 A digital imaging equipment.Specimens photos were taken by the Olympus E-M5 II camera.All species were described in detail,literature references,specimen collection,distribution information and morphological feature figure were provided.Genus Rhabdoblatta has five new species: R.discolor sp.nov.,R.fulvida sp.nov.,R.nigrotibilis sp.nov.,R.sigillata sp.nov.,R.tibetana sp.nov..Genus Stictolampra has one new species: S.yunnanica sp.nov..Genus Rhabdoblatta has one new combination: Rhabdoblattella kabakovi(BeyBienko,1969)comb.nov.,one new synonym: Rhabdoblattella hainanensis Wang et Wang,2017 syn.nov.All the specimens including the type specimens of the new species were deposited in the Shanghai Entomology Museum of the Chinese Academy of Sciences.2.Cladistic study on Epilamprinae from China14 characters of 12 species of 8 genera in Epilamprinae and 19 characters of 15 species of genus Rhabdoblatta were selected to build cladistic trees by RaxmlHPC software.The results were as follows:(1)The species of the genus Rhabdoblattella,the genus Rhabdoblatta,the genus Stictolampra,and the genus Pseudophoraspis were all together,with the support rate of 85%,59%,89% and 84%,respectively.The genus Comptolampra,the genus Opisthoplatia,the genus Calolamprodes,and the genus Anisolampra were grouped as a clades.The genus Opisthoplatia is closely related to the genus Calolamprodes,and the support rate is 29%.(2)R.pisarskii and R.princisi were grouped as a clades,the support rate is 60%.R.beybienkoi and R.sigillata sp.nov.were grouped as a clades,the support rate is 81%.R.elegans and R.nigrotibilis sp.nov.were grouped as a clades,the support rate is 82%.R.sinensis and R.parvula were grouped as a clades,the support rate is 87%.R.immaculata and R.discolor sp.nov.were grouped as a clades,the support rate is 79%.3.Biogeographic study on Epilamprinae from ChinaBy referring to existing specimens' information and literatures,characteristics of geographical distribution of the Epilamprinae was analyzed.The results show that: the number of Epilamprinae is the most abundant in the Oriental realm,including 239 species,followed by the Neotropical realm,including 154 species,and the number of Epilamprinae in the Nearctic realm is the least,including 1 species.The species of Epilamprinae is mainly distributed in the southern China.Most species were distributed in Yunnan province.The genus Rhabdoblatta has most abundant species.The species Rhabdoblatta brunneonigra was the most widely distributed one.The number of Epilamprinae is the most abundant one in South China area,including 43 species.Followed by Central China area,including 19 species.Of all the species recorded in this paper,57 species were endemic to Oriental region,2 species were endemic to Palaearctic region.Research of Epilamprinae in our country is aimed at providing scientific basis for the diversity protection,resource utilization and exploitation of the species. |
