The Neotropical genus Cephaloleia Chevrolat (Coleoptera: Chrysomelidae: Cassidinae) includes 214 species distributed from the south of Mexico to Argentina. Cephaloleia beetles feed mostly on plants from the order Zingiberales. The interactions between Cephaloleia beetles and their Zingiberales host plants is proposed as one of the oldest and most conservative associations. Here we describe a new species of Cephaloleia (Cephaloleia
kuprewiczae
sp. n.) that feeds on two species of bromeliads (Pitcairnia
arcuata and Pitcairnia
brittoniana, Bromeliaceae: Pitcairnioideae). Cephaloleia
kuprewiczae was previously described as Cephaloleia
histrionica. This study includes evidence from DNA barcodes (COI), larval and adult morphology and insect diets that separates Cephaloleia
kuprewiczae from Cephaloleia
histrionica as a new species. 相似文献

A new species of Baetidae, Gratia
baibungensis
sp. n., is described and illustrated based on nymphal stage collected from the southeastern Tibet (Xizang) and the genus is reported for the first time from China. This new species can be readily differentiated from its congeners by the absence of a protuberance on the posterior margin of the abdominal tergum X, glabrate simple submarginal setae on the labrum, and the posterior margin of sterna VI–IX having much longer spatulate setae. 相似文献

Four new species of shallow-water marine gastropods belonging to the family Rissoidae are described from the Archipelago of the Azores: Setia
alexandrae
sp. n., Setia
ermelindoi
sp. n., Setia
netoae
sp. n., and Manzonia
martinsi
sp. n. These novelties increase the regional rissoid fauna to 39 species, of which 29 live in shallow-water habitats. A list of the species of Rissoidae from the Azores is presented based on data from the literature and new material examined. 相似文献

Two new species of Stenochironomus Kieffer (Diptera: Chironomidae: Chironominae), Stenochironomus
brevissimus
sp. n. and Stenochironomus
linanensis
sp. n., are described from China and the male imagines are illustrated. Stenochironomus
brevissimus
sp. n. can be separated from the so far known species by having very short and small, spatulate superior volsella with two long setae, whereas Stenochironomus
linanensis
sp. n. is easily separated from the other species of Stenochironomus by the following characters: wings transparent, body yellow, superior volsella finger-like, with nine long setae, elongated inferior volsella with four long setae and one well developed terminal spine; tergite IX with 10−15 long setae medially. A key to the males of Stenochironomus occurring in China is given. 相似文献

The new species Telamoptilia
grewiae, reared from leafmines on Grewia
biloba (Malvaceae) is described with details on adult and immature stages. The larval head and the pupa are described for the first time in Telamoptilia Kumata & Kuroko, 1988, and are illustrated with scanning electron micrographs and line drawings. Photographs of adult habitus, wing venation, male and female genitalia, as well as host plant and mines are provided. The apomorphic adult and larval characters of the new species in Telamoptilia are discussed in relation to the recognition of the genera Telamoptilia and Spulerina Vári, 1961. 相似文献

Two new species of Afidentula, Afidentula
dentata
sp. n. and Afidentula
jinpingensis
sp. n. are described from China. Afissa
siamensis Dieke is moved to Afidentula
comb. n.. All three species are described and illustrated, and a distribution map is given. A key to Asian species of Afidentula is updated. Diagnostic similarities and differences between Afidentula and Afidenta are discussed and illustrated. 相似文献

Manipulation of araneid spider web architecture by the polysphinctine parasitoid Zatypota picticollis (Hymenoptera: Ichneumonidae: Pimplinae) 下载免费PDF全文
We found that the koinobiont ectoparasitoid wasp Zatypota picticollis is exclusively associated with three orb weaving spiders Cyclosa conica, Mangora acalypha and Zilla diodia from the family Araneidae. Under the influence of the parasitoid's final instar larva the spiders built a specific web architecture, which differed considerably from the capturing orb web. Manipulated webs of C. conica and M. acalypha lacked the spiral, stabilimentum and central hub, and the radials were reduced in number. The manipulated web of Z. diodia consisted of one strong horizontally oriented thread. 相似文献

A total of six soil samples were collected around rhizosphere of citrus plants during 2010 from Melkassa Agricultural Research Center experimental station, Ethiopia. From these samples two most important ecto-plant parasitic nematodes of the genus Xiphinema were found and analysed. The genus Xiphinema is a large group of the phylum nematoda which constitutes more than 260 species. They are polyphagous root- ectoparasites of many crop plants and some species of this genus cause damage by direct feeding on root tips and transmit nepoviruses. The delimitation and discrimination of two species in the genus is presented, described herein as Xiphinema
elongatum and Xiphinema
pachtaicum. Morphological and morphometric data were done using light microscopy and results of both species were fit within the previously described nematode species of Xiphinema
elongatum and Xiphinema
pachtaicum. 18S rDNA were analysed using Bayesian inference (BI) method to reconstruct phylogenetic relationships of the studied Xiphinema sp. (
Xiphinema
elongatum and KP407872
Xiphinema
pachtaicum) with other Xiphinema species. The 18S rDNA sequence of Xiphinema
pachtaicum was alike to previously described species from the GenBank but Xiphinema
elongatum exhibited very small levels of nucleotides differences (0.4%) which might be possible intra-specific divergence. Though this region of rDNA has less resolution on complex species, its combination with morphological and morphometric analyses, suggests these species as Xiphinema
elongatum and Xiphinema
pachtaicum with the GenBank accession number of KP407873 and KP407872, respectively. Short notes, morphological measurements, illustrations, and molecular data are given to these species. These species are reported for the first time from Ethiopia and it provides new geographical information of these organisms. KP407873相似文献

A new species of pycnogonid collected by the Chinese research vessel, R/V HY IV, during deep sea cruises to the South China Sea in 2013, is described. The new species, Hemichela
nanhaiensis, obtained from more than 1300 m depth, is distinguished from the other two species in the genus by the characters of the chela dactylus with 12 denticulations on the inner margin and by the presence of taller tubercles on the lateral processes. 相似文献
