Spread of and Damage by an Exotic Lacebug, Corythuca ciliata (Say, 1832) (Hemiptera: Tingidae), in China

ABSTRACT: Corythuca ciliata has spread rapidly through southern China. Integrated control methods are needed to effectively control this pest,

Complete Mitochondrial Genome of the Citrus Spiny Whitefly Aleurocanthus spiniferus (Quaintance) (Hemiptera: Aleyrodidae): Implications for the Phylogeny of Whiteflies

In this study, we sequenced the complete mitochondrial genome (15,220 bp) of the citrus spiny whitefly, Aleurocanthus spiniferus (Quaintance), a well-known pest from the superfamily Aleyrodidae. The A. spiniferus mitogenome contains 36 genes, including 13 protein-coding genes (PCGs), 21 transfer RNAs (tRNA), two ribosomal RNAs (rRNA) and a large non-coding region (control region, CR). Like most whiteflies, the A. spiniferus mitogenome had a large degree of rearrangement due to translocation of the nad3-trnG-cox3 gene cluster. The 13 PCGs initiated with ATN and generally terminated with TAA, although some used TAG or T as stop codons; atp6 showed the highest evolutionary rate, whereas cox2 appeared to have the lowest rate. The A. spiniferus mitogenome had 21 tRNAs with a typical cloverleaf secondary structure composed of four arms. Modeling of the two rRNA genes indicated that their secondary structure was similar to that of other insects. The CR of A. spiniferus was 920 bp and mapped between the nad3-trnG-cox3 and trnI-trnM gene clusters. One potential stem-loop structure and five tandem repeats were identified in the CR. Phylogenetic relationships of 11 species from the Aleyrodidae were analyzed based on the deduced amino acid sequences of the 13 PCGs and evolutionary characteristics were explored. Species with more genetic rearrangements were generally more evolved within the Aleyrodidae.

Four new species of the genus Amphinemura (Plecoptera: Nemouridae) from China

Abstract Four new species of Amphinemura from China are described: Amphinemura biloba Du & Zhou, sp. nov., A. macrotubifera Du & Zhou, sp. nov., A. sclerotica Du & Zhou, sp. nov., and A. tubulata Du & Zhou, sp. nov.

The first records of Mesocapnia (Plecoptera: Capniidae) from China with description of a new species

Three species of the capniid genus Mesocapnia are reported from the Inner Mongolia Autonomous Region of China, M. variabilis and M. gorodkovi, and M. daxingana sp. nov. These are the first records for the genus from China, extending the distribution of Mesocapnia into the Inner Mongolia Autonomous Region.

A remarkable new species of winter stonefly (Plecoptera: Capniidae) from Southeastern China

A new species of the genus Capnia s.l., C. zijinshana Du & Chen, sp. nov. is described and illustrated from Jiangsu Province, of southeastern China. The new species is distinguished from other known Chinese capniid species by the unique thoracic sclerites and genitalic characters.

A new species of Suwallia (Plecoptera: Chloroperlidae) from China

A new species of the genus Suwallia, S. wolongshana sp. nov. is described and illustrated from specimens collected in Sichuan Province, China. The new species is characterized by the two sclerotized bands between the hemitergal processes. The new species is the fourth recorded species of Suwallia from China.

The first record of a species of Perlidae from Jiangsu Province, China: a new species of Neoperla (Plecoptera: Perlidae).

A new species of Neoperla (Plecoptera, Perlidae), N. jiangsuensis Chen & Du from Jiangsu Province, China, is described and illustrated. Neoperla jiangsuensis is characterized by the aedeagal sac with two C-shaped rows of large stout spines laterally, a patch of small spines, and with an apical double ear-shaped membranous lobes. The new species is the first recorded species of Perlidae known from the eastern coastal province of Jiangsu, China.

Four New Species of the Genus Nemoura (Plecoptera: Nemouridae) from China

ABSTRACT Four new species of the genus Nemoura from China are described: N. cocaviuscula Du and Zhou, sp. nov., N. lui Du and Zhou, sp. nov., N. magnispina Du and Zhou, sp. nov., and N. rotundprojecta Du and Zhou, sp. nov.

A remarkable new species of Nemoura (Plecoptera: Nemouridae) from Chuxiong Yi Autonomous Prefecture of Yunnan Province, China

A new species of the genus Nemoura, N. latilongispina sp. nov. from Chuxiong Yi Autonomous Prefecture of Yunnan Province, southwestern China is described and illustrated. The new species is characterized by ventral sclerite of epiproct extended laterally, forming upcurved plates fringed with long spines along upper margin, and by the strongly sclerotized, fork-shaped cercus.

A new species of Nemoura (Plecoptera: Nemouridae) from Jiangsu Province, China, with new illustrations for Nemoura nankinensis Wu

A new species of Nemoura (Plecoptera: Nemouridae), N. fusiformis sp. nov. from Jiangsu Province, China, is described and illustrated. The new species is characterized by a strongly sclerotized large hook formed by outer margin of the outer lobe of the paraproct and by the outer sclerite of cercus with a sub-triangular medial process. The new species is compared with similar taxa. Additionally, supplementary illustrations for N. nankinensis Wu, 1926 are also provided.
