A. http://www.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. In- secta 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 Abstracts, 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. Managing editor: Paul E. Skelley, e-mail: [email protected] Production editors: Michael C.

Evans USDA/ APHIS/ PPQ c/o Systematic Entomology Laboratory Bldg 005, Room 137, BARC-WEST 10300 Baltimore Ave. Beltsville, MD 20705 Abstract. A new genus and species of armored scale insect (Hemiptera: Diaspididae), Protomorgania koebelei Dooley and Evans, is described and illustrated from specimens collected by Albert Koebele on Pittosporum sp. (Pittosporaceae) in Australia around the year 1900. A key to the genera of armored scale insects similar to Pro- tomorgania and known to occur in Australia is provided. Key words. Aspidiotinae, Coccoidea, taxonomy Introduction Albert Koebele was sent by the U.S. Department of Agriculture (USDA) to Australia around the year 1900 to search for natural enemies of various species of exotic scale insects (Hemiptera: Coccoidea) that had become pests in California (Boardman 1977). In the process of collecting natural enemies, he also collected many specimens of scale insects (Weathers and Lawton 1982). The senior author ex- amined Koebele’s collection of armored scales at the California Academy of Sciences Collection in San Francisco, California (CASC). Upon examination of specimens processed and slide mounted from the dried specimens in the collection, a new genus and species of armored scale insects was discovered and is here described. Material and Methods The method used for preparation of slide mounted specimens follows that used by Gill (1997), Miller and Davidson (2005), and the Systematic Entomology Laboratory (SEL), USDA (Anonymous 2006). Specimens of adult female armored scales were placed into test tubes containing 5% KOH and heated in a bubbling hot water bath for 15 minutes. They were then washed in water to remove potassium hydroxide and soaked in Essig’s aphid fluid with the addition of two drops of double stain for 10-15 minutes. The stained specimens were placed in 70% ethanol for 15 minutes and then trans- ferred into 90% ethanol for 10 minutes. Specimens were transferred to clove oil for 15 minutes prior to slide mounting in Canada balsam. Images and measurements were taken with a SMZ 1500 wide field and a Nikon Eclipse 80i compound microscope using a Nikon DS-Fi1 Digital Image camera. Measurements were taken from 4 specimens and given in micrometers (μm). Specimen Depositories.

Morphology and Terminology. A glossary for the morphological terms used to describe armored scales can be found in Miller and Davidson (2005). The following abbreviations are used: abdominal segments 1 through 8 (A1-A8); cephalon (C1); pygidial lobes–median or first lobe (L1), second lobe (L2), third lobe (L3,) and fourth lobe (L4); perispiracular pores (pps); perivulvar pores (pvp); and thoracic seg- ments–prothorax (T1), mesothorax (T2) and metathorax (T3). Key and illustrations A key to the genera of armored scales known to occur in Australia that are similar to Protomorgania n. gen. is provided. The genera in this group belong to the subfamily Aspidiotinae and are character- ized by having a broad body with a constriction or incision between the prothorax and mesothorax. The metathorax and abdomen are usually broader than the region from the anterior margin of the body to the mesothorax. In addition, most of the species in this group lack perivulvar pores and unlike most of the species in other aspidiotine genera which lack perispiracular pores,
