We explore the potential value of DNA barcode divergence for species delimitation in the genus Caryocolum Gregor & Povolný, 1954 (Lepidoptera, Gelechiidae), based on data from 44 European species (including 4 subspecies). Low intraspecific divergence of the DNA barcodes of the mtCOI (cytochrome c oxidase 1) gene and/or distinct barcode gaps to the nearest neighbor support species status for all...

The discovery of the Aleurocanthus cf. spiniferus (Tea spiny whitefly morphotype; previously found in Tokyo) for first time Shizuoka Prefecture raised possibility that this species had invaded Honshu Island, Japan. Unlike allied species, and A. camelliae, which have been intercepted from China to Japan, origin current remains unclear. Despite status as a minor pest on ornamental plant, Eurya ja...

Definition of monophyletic supraspecific units in the harpacticoid subfamily Stenheliinae Brady, 1880 has been considered problematic and hindered by the lack of molecular or morphology based phylogenies, as well as by incomplete original descriptions of many species. Presence of a modified seta on the fifth leg endopod has been suggested recently as a synapomorphy of eight species comprising t...

A new nematode species was recovered from the syconia of Ficus altissima from the residential area of Huajingxincheng, Guangzhou, Guangdong Province, China during a survey of nematode diversity. Schistonchus altissimus n. sp. is characterised by having females with a short post-uterine sac, an ovoid spermatheca and a conoid tail with a mucron in the female, excretory pore located near the lip; ...

Two new species of Fergusobia are described. Both were collected from flat leaf galls from South Australia, one on Eucalyptus microcarpa and the other on E. porosa. Fergusobia microcarpae n. sp. Davies is characterised by the combination of a C-shaped parthenogenetic female with a short, broadly rounded conoid tail, an arcuate to open C-shaped infective female with an hemispherical tail tip, an...

The genetic variability of whitefly (Bemisia tabaci) species, the vectors of cassava mosaic begomoviruses (CMBs) in cassava growing areas of Kenya, Tanzania, and Uganda, was investigated through comparison of partial sequences of the mitochondria cytochrome oxidase I (mtCOI) DNA in 2010/11. Two distinct species were obtained including sub-Saharan Africa 1 (SSA1), comprising of two sub-clades (I...

Summary Hirschmanniella diversa and H. imamuri parasitise the lotus, Nelumbo nucifera. spp. are most important pests of lotus cultivation in Japan, but distribution species dominancy not fully understood. In this study, we aimed to collect individuals from roots major areas Japan identify them morphologically molecularly using 18S, D2-D3 regions rRNA mitochondrial cytochrome c oxidase subunit I...

Giant clams are an important ecological component of coral reefs in the Red Sea, as they enhance reef’s productivity and provide habitat that can increase diversity. Three species giant clams, namely Tridacna maxima , T. squamosa squamosina have been described within Sea. However, due to its scarcity, information about distribution ecology Saudi Arabian Sea is still lacking. This study used DNA...

During an investigation of a natural sandy beach on Jeju Island, South Korea, species marine nematode belonging to the rare genus Manunema was discovered and is now being reported. Up until now, no molecular sequences this have been available, its position within system has subject dispute. Currently, classified order Plectida, either as only family Peresianidae in superfamily Haliplectoidea or...
