The female genitalia and male terminalia were first excised and macerated in 10% potassium hydroxide (KOH) at 55°C followed by rinsing in distilled H2O. They were temporarily stored in 75% ethanol for examination and illustration and eventually sealed in polyethylene genitalia vials containing 100% glycerine and attached to the specimen’s pin. Morphological features were illustrated using a 10×10 ocular grid on a Olympus SZ60 stereo microscope and later digitally redrawn using Adobe Illustrator® software. The vestiture on male terminalia is not shown. Wing length was measured from the tegula to the distal tip of the wing. Photographs of pinned specimens were taken with a Olympus E-30 digital SLR, a 50 mm macro lens (equivalent of 100 mm focal length in 35 mm photography), and a 25 mm extension tube. The specimens were illuminated by a LED ring-light fitted with a dome for even and soft light.
In recording data for type specimens as well as non-type specimens, information is given (where available) in a standard manner, i.e., locality, geographic co-ordinates, elevation, date of collection (month indicated in lower case Roman numerals where hyphens indicate missing entries for day, month, year), habitat information, collector, and depository. Female (♀) and male (♂) symbols indicate the sex while a question mark (?) refers to specimens of indeterminable sex (i.e., with broken or missing abdomen). Each specimen is listed with a unique AAM specimen number that will allow the re-investigation as well as provide a unique identifier (LSID http://lsids.sourceforge.net/) in databases like GBIF (http://www.gbif.org/) in the future. AAM is an abbreviation for ‘

This species was first recognised as new by me based on material made available by R. Copeland in 2002. However, when I visited the BMNH in February 2010, I found several specimens labelled as types of a yet unpublished name by J. Bowden. Bowden had divided the species into three subspecies, the nominal subspecies based on the material from the Kiangani River and Makueni, one subspecies based on the single female from ‘British East Africa’, and another subspecies based on the single male from Uganda. The material from Kiboko collected in 1981 was interestingly not included by J. Bowden in his type material. I regard all these specimens as well as all other listed material as belonging to the same species. This species represents the first

I would like to thank the many museum curators who made specimens available through loans and for their hospitality when visiting the collections. In particular, I would like to thank Robert Copeland for providing the majority of specimens from Kenya (now in NMKE) and Brian Brown for making the TIGER samples available for study. I thank the three reviewers for pointing out inconsistencies in the descriptive approach taken here and also Shaun Winterton and Martin Hauser for the discussions on modern species descriptions that improved the present paper.
