P. O. 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.

A new genus, Dejunaleon Miller and Stange, is described with two new species: Dejunaleon loja Miller and Dejunaleon maculosus Stange (Neuroptera: Myrmeleontidae: Brachynemurini). A key to species is provided as well as distributional data. A description of the larva of Dejunaleon loja is given. A key to genera of the tribe Brachynemurini is provided based on larvae and adults. Key Words. Antlion, Dejunaleon, larva, keys adults and larvae. Resumen. Se describe un género nuevo, Dejunaleon Miller y Stange, de Ecuador con dos especies nuevas: Dejunaleon loja Miller y Dejunaleon maculosus Stange (Neuroptera: Myrmeleontidae: Brachynemurini). Se provee una clave para las especies con datos sobre sus distribuciones. Se describe la larva de Dejunaleon loja. Se presenta una clave para los generos de la tribu Brachynemurini basada sobre los adultos y larvas. Introduction Dejunaleon Miller and Stange, new genus, is described from Ecuador and includes two new spe- cies, Dejunaleon loja Miller and Dejunaleon maculosus Stange. These straw colored species, as adults, superfi cially resemble those of the genus Dejuna Navás but differ especially in the structure of the male genitalia and female terminalia. The larvae of Dejunaleon loja were found living in loose soil on 45° slopes at the base of an agave plant. The larva (Fig. 21–29) is distinctive in the abundance of sessile microspinose dolichasters on the dorsal surface of the body including clusters of black sausage-shaped dolichasters, which are microspinose, at the submedian and anterior area of the mesothorax and meta- thorax and along the median area of tergites I–V. Dejunaleon is unusual in having sexually dimorphic characters. The forefemoral sense hair is longer in the females than in the males and the hind tibial spurs are longer in the females. Considerable variation in these characters and other characters in Dejunaleon loja indicate that this is a complex species and may represent at least two cryptic species. Much more collecting is needed to evaluate the pattern of extensive variation. The male genitalia are the most complex that we have seen in the Brachynemurini, being spring-loaded and box shaped with multiple paramere articulations (hinges). Materials and Methods Photographs were taken using an Auto Montage (Leica Z16 APO zoom lens attached to a JVC 3-CCD digital camera (KY-F75U)), and montaged with Syncroscopy Automontage software. Genitalia were enhanced in contrast to clearly defi ne sclerotized areas using the Picasa computer program. Genitalia were pressed down by a cover slip for stability during photography, but a description is also given of the genitalia in an uncompressed state. Larvae were originally treated with KAAD larval fi xative and then stored in 75% ethanol. Larvae were reared using Mediterranean grain moth larvae (Ephestia kuehniella Zeller; Lepidoptera: Pyralidae). Adults were collected in grassy areas by net and with light traps. Larvae were collected by sifting fi ne earth through screens from beneath Agave plants. Descrip- tion of male genitalia are given for compressed and non-compressed views. 2 • INSECTA MUNDI 0536, March 2017 MILLER AND STANGE Specimens studied are deposited in the following institutions: CASC California Academy of Sciences, San Francisco, California, U.S.A.
