Abstract

Neuroterus apenninus Trotter, 1923 associated with a Cerris section oak, Quercus cerris L., was rediscovered in Italy in 2017. Alessandro Trotter (1903) described a leaf gall collected on Q. cerris from the Italian Apennines; he did not obtain the gall inductor and ascribed the galls to the genus Neuroterus, based on morphological similarity with other Neuroterus galls. We have found the same gall and obtained the gall inducer. Detailed study of morphological characters of adults revealed that the species belongs to the genus Cerroneuroterus Melika Pujade-Villar, 2010. The asexual generation of Cerroneuroterus apenninus comb. n. is described for the first time, a neotype is designated, and a diagnosis, host associations and biological notes are given; an identification key to the Western Palaearctic Cerroneuroterus species is provided.

摘要

2017 年，意大利重新发现了与栓皮栎属栎树（Quercus cerris L.）相关的 Neuroterus apenninus Trotter，1923。亚历山德罗·特罗特（Alessandro Trotter）（1903 年）描述了一种在意大利亚平宁山脉的栓皮栎上收集到的叶瘿，他没有获得瘿诱导物，并根据与其他 Neuroterus 瘿的形态相似性，将这些瘿归因于 Neuroterus 属。我们发现了相同的瘿并获得了瘿诱导物。对成虫形态特征的详细研究表明，该物种属于 Cerroneuroterus Melika Pujade-Villar，2010 属。首次描述了 Cerroneuroterus apenninus comb. n. 的无性世代，并指定了一个新的模式标本，提供了诊断、寄主关系和生物学注释；提供了一个鉴定西古北区 Cerroneuroterus 种的关键。
