Description of a new species of <i>Hyadaphis</i> Kirkaldy (Hemiptera: Aphididae) from Turkey

<p>Apterous and alate viviparous females of <i>Hyadaphis bupleuriphila</i> sp. n. living on <i>Bupleurum</i> sp. (Apiaceae) and further undetermined Apiaceae are described from the Ankara province in central Turkey. The new species is morphologically similar to <i>Hyadaphis coerulescens</i> (Narzikulov, 1965), <i>H. ferganica</i> Mukhamediev & Akhmedov, 1979 and <i>H. foeniculi</i> (Passerini, 1860). A key to the apterous viviparous females of <i>Hyadaphis</i> spp. in Turkey is given.</p> <p><a href="http://www.zoobank.org/urn:lsid:zoobank.org:pub:2A0A29EA-5FE7-459D-A337-CFA47601874E" target="_blank">http://www.zoobank.org/urn:lsid:zoobank.org:pub:2A0A29EA-5FE7-459D-A337-CFA47601874E</a></p

Descriptions of little-known and unknown morphs of <i>Zelkovaphis caucasica</i> (Hemiptera: Aphididae: Eriosomatinae), with an analysis of its phylogenetic position

<div><p><i>Zelkovaphis caucasica</i> is a little-known Caucasian species of leaf-rolling aphids on <i>Zelkova carpinifolia</i>, and was not included in a previous morphological phylogenetic analysis of the tribe Eriosomatini. We redescribe little-known emigrants of <i>Z</i>. <i>caucasica</i> and describe first instars borne by the emigrants, with keys to species for these morphs of the genus <i>Zelkovaphis</i>. Based on the present specimens and a previously published description, we added <i>Z</i>. <i>caucasica</i> to a published data matrix for Eriosomatini species, and re-analysed the phylogenetic relationships of the tribe Eriosomatini. Successive weighting analysis indicated that <i>Z</i>. <i>caucasica</i> branched off at the base of the Eriosomatini phylogeny, as well as other leaf-rolling species on <i>Zelkova</i>. It is therefore suggested that, like other leaf rollers on <i>Zelkova</i>, <i>Z</i>. <i>caucasica</i> is a relict that has survived in glacial refugia.</p></div
