Box 141874 Gainesville, FL 32614-1874 USA http://centerforsystematicentomology.org/ Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published on any non-marine arthropod. Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. Insecta Mundi publishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources including the Zoological Record, CAB Ab- stracts, etc. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an individual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology. Chief Editor: David Plotkin, e-mail: [email protected] Assistant Editor: Paul E.

Thirty-one species of mealybugs (Hemiptera: Pseudococcidae) are reported from South Korea based upon monitoring surveys conducted from 2010 to 2016, along with a dichotomous key to separate them. Six spe- cies, Nipaecoccus nipae (Maskell), Palmicultor lumpurensis (Takahashi), Planococcus citri (Risso), Pseudococcus dendrobiorum Williams, Pseudococcus longispinus (Targioni-Tozzetti), and Pseudococcus orchidicola Takahashi, known only to occur in greenhouses, are considered as adventive mealybug species to South Korea; of these, P. citri has already established in the exterior environment in South Korea. Key Words. Mealybugs, dichotomous key, identifi cation, adventive species. Introduction Mealybugs (Hemiptera: Pseudococcidae) comprise some of the most serious pests on various agri- cultural crops and pose serious problems when introduced into new areas of the world without their natural enemies (Kwon et al. 2003a; Miller et al. 2005). They cause direct injury to plants by depleting the plant sap or by injecting plant toxins. In addition, more evidence has been presented concerning the role of mealybugs as vectors of plant viruses (Williams 2004). Kwon et al. (2003a, b) listed 53 species in 19 genera of mealybugs in the latest catalogue of the mealybugs of the entire Korean Peninsula with characteristics, keys, host plants and distribution based on surveys and previous published records. Their catalogue included 15 species from North Korea re- ported by Russian entomologists such as Borchsenius (1956), Danzig and Ivanova (1976), and Danzig (1980; 1988) and four species accidentally found in greenhouses on ornamental plants imported into South Korea. Although known only to occur in greenhouses or nurseries in South Korea, mealybugs such as Nipaecoccus nipae (Maskell), Palmicultor lumpurensis (Takahashi), and Pseudococcus longispinus (Targioni-Tozzetti) are of economic signifi cance (Williams 2004), and no comprehensive analysis has been conducted in order to determine if they are adventive or indigenous mealybugs in South Korea. Since then, mealybugs found in greenhouses in South Korea have been cited in papers (Lee 2010; Park 2010; Koo et al. 2017) including a new species, while other species have been synonymized with previ- ously described taxa (Pellizzari and Danzig 2007; García et al. 2017). The purpose of this paper is to provide an updated list of South Korea’s mealybug species with an identifi cation key and list adventive mealybug species of South Korea. Materials and Methods Information on the number of mealybug species known to occur in the Korean Peninsula and in all zoogeographic regions was gathered from papers reporting South Korea’s mealybugs (Paik 1972, 1978; Paik 2000; Kwon et al. 2002; Kwon et al. 2003a, b; Lee 2010; Lee and Suh 2011; Koo et al. 2017) and ScaleNet (García et al. 2017), a website that includes information on species of scale insects that has been published worldwide. Data from monitoring surveys of exterior environments and nurseries/ 2 • INSECTA MUNDI 0581, November 2017 SON AND SUH greenhouses during the past seven years (2010 to 2016) was extracted from the Plant Quarantine Inte- gration System (PQIS) database developed by the Animal and Plant Quarantine Agency (APQA). Codes for the zoogeographic regions recognized are as follows: Palaearctic (PA), Oriental (OR), and Austral- asian (AU). The nomenclature used here for the Pseudococcidae follows that of the ScaleNet database (García et al. 2017). This paper provides a dichotomous key concerning 31 species of mealybugs from South Korea except for six adventives species. But during this project, Crisicoccus coreanus (Kanda) was not collected and we were not able to examine the specimen of this species although it has been documented for the South Korea’s fauna of mealybugs. Terminology for the morphological structures used in the key follows that of Williams (2004). Results According to the scale insect database ScaleNet (García et al. 2017), there are 1,980 species of mealybugs worldwide. Based on our review of the literature and survey results, there are 31 species in South Korea which represents 2% of all described species. A dichotomous key to the mealybugs in South Korea is provided below for the correct identifi cation of mealybug species by port identifi ers at the various stations of the APQA. As far as we are aware, no mealybug species have been
