Box 141874 Gainesville, FL 326141874 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. medi cal 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 and CAB Abstracts. 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.

Matsucoccus krystalae Ahmed and Miller, new species, (Hemiptera: Coccomorpha: Matsucocci dae) is described based on morphological characters of adult females and thirdinstar males. We designate the lectotype of Matsucoccus alabamae Morrison. Matsucoccus alabamae Morrison and M. gallicolus Mor rison are redescribed, also based on adult females and thirdinstar males. Detailed illustrations and descriptions are presented for each species and an identification key for the five species occurring in the eastern U.S. is provided. Analysis of 18S, 28S D2/D3, and 28S D10 loci were performed to support morphological determination. Barcodes using 5′ COI of M. alabamae and M. krystalae were generated, the first such data from authoritatively identified Matsucoccus species. Of particular interest is that most of the specimens in the study were taken in Lindgren funnel traps. Key words. Distribution, southern US, taxonomy, Lindgren funnel trap, scale insects. ZooBank registration. urn:lsid:zoobank.org:pub:803B5050F60D4E9681997E100258A4C4 Introduction We became interested in the Matsucoccus Cockerell, 1909 of Florida when Krystal Ashman (Florida State Col lection of Arthropods, Division of Plant Industry, Florida Department of Agriculture and Consumer Services) noticed thirdinstar males of an unknown species in Lindgren funnel traps set out as part of a Cooperative Agricultural Pest Survey (CAPS) survey in 2017. At that time, the only published record of Matsucoccus in Flor ida was a species identified as M. gallicolus Morrison based on a single collection. We have since determined that these specimens were a new species, not M. gallicolus, and are here identified as M. krystalae, new species. Recently Ahmed and Miller (2020) reported M. alabamae from Florida that was collected in Lindgren funnel 2 · October 30, 2020 Ahmed et al. traps. Because specimens of both species are often found in Lindgren funnel traps (Ahmed and Miller 2020) and because some species of the genus can cause significant damage to their pine hosts globally, we decided that it would be useful to study the species that occur in Florida. The genus Matsucoccus, commonly called pine scales, pine bast scales or matsucoccids, includes a group of scale insects that occur in North America, East Asia and Europe. There are 32 extant and six extinct Matsucoccus species, 17 (16 native and 1 invasive) are reported from the U.S. and five occur in the eastern U.S., all feed on trees in the Pinaceae. Herbert (1919) described Matsucoccus fasciculensis from California which was the first report of a Matsucoccus species in the United States. Matsucoccus matusmurae (Kuwana), a Japanese species, was later reported to occur in the eastern U. S. (Herbert 1921; Morrison 1928). However, it was eventually determined that the eastern U. S. specimens were two different species,M. alabamae Morrison and M. gallicolus Morrison (Mor rison 1939). The generalized life history ofMatsucoccus species is as follows (Fig. 1). Eggs are laid in an ovisac that is attached to the body of the adult female and to the pine host. The eggs hatch and firstinstar nymphs seek out Figure 1. Life cycle of Matsucoccus alabamae.
