Abstract

The obscure mealybug Pseudococcus viburni (Signoret) (Hemiptera: Pseudococcidae) is recorded for the first time from Colombia based on specimens collected on Opuntia cylindrica (Lam.) DC., Mammillaria sp. (Cactaceae), Escallonia paniculata (Ruiz & Pav.), Roem. & Schult. (Escalloniaceae), Ficus carica L. (Moraceae), Coffea arabica L. (Rubiaceae), Citrus sp. (Rutaceae), Cestrum nocturnum L. and Solanum betaceum Cavanilles (Solanaceae). Multiple methods were used to identify P. viburni because it belongs to the “Pseudococcus maritimus” complex, a group composed of more than 60 species with high variation in morphological characteristics. The specimens were identified based on the morphology and morphometric analysis of third-instar nymphs and adult females. This morphological identification was corroborated by data on geographical distribution, plant hosts and a molecular identification using two different loci, CO1 (mtDNA) and the 28S ribosomal gene (nuclear genome). An updated list of species of Pseudococcus Westwood recorded from Colombia and information on morphological variation found in the studied specimens from Brazil and Colombia are provided.

哥伦比亚威氏假球菌（半翅目：假球菌科）的首次报告：形态计量学和分子分析，并注意巴西和哥伦比亚标本的形态变异

根据在仙人掌（Lam.）DC上采集的标本，首次从哥伦比亚记录到了不知名的粉蚧viburni假球菌（Signoret）（半翅目：假球菌科）。，Mammillaria sp.（仙人掌科），Escallonia paniculata（Ruiz&；Pav.），Roem&；舒尔特。（Escalloniaceae）、榕（Ficus carica L.）（Moraceae）、小粒咖啡（Coffea arabica L.）（茜草科）、柑橘属（Rutaceae）、夜蛾属（Cestrum nocturnum L.）和茄属（Solanaceae）。本研究采用多种方法对毕氏假单胞菌进行鉴定，因为它属于“假球菌”复合体，该复合体由60多种形态特征高度变异的物种组成。根据三龄若虫和成年雌性的形态学和形态计量学分析，对标本进行了鉴定。这种形态鉴定通过地理分布、植物宿主的数据和使用两个不同基因座CO1（mtDNA）和28S核糖体基因（核基因组）的分子鉴定得到了证实。提供了哥伦比亚记录的最新韦斯特伍德假球菌物种清单，以及巴西和哥伦比亚研究标本中发现的形态变异信息。

期刊介绍： Published regularly since 1920, Acta Zoologica has retained its position as one of the world''s leading journals in the field of animal organization, development, structure and function. Each issue publishes original research of interest to zoologists and physiologists worldwide, in the field of animal structure (from the cellular to the organismic level) and development with emphasis on functional, comparative and phylogenetic aspects. Occasional review articles are also published, as well as book reviews.
