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 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. Guidelines and requirements for the preparation of manuscripts are available on the Insecta Mundi website at http://centerforsystematicentomology.org/insectamundi/ Chief Editor: David Plotkin, [email protected] Assistant Editor: Paul E.

[email protected] Robert B. Miller Florida State Collection of Arthropods Gainesville, Florida, U.S.A. Abstract. Nine species of Navasoleon (Neuroptera: Myrmeleontidae: Nemoleontini) are recognized in the present work with the description of seven new species: N. amazonas Stange, N. brasiliensis Miller, N. egeri Stange, N. lithophilus Miller, N. lotti Stange, N. tarsalis Miller, and N. venezolanus Stange. Navasoleon bosqui (Navás) is designated a nomen dubium. A key to the species is provided as well as to the genera of Nemoleontini with closing pretarsal claws. The larvae of two species are described and keyed with biological notes. Biological data presented in Miller and Stange (1985), erroneously attributed to N. bolivianus (Banks), has now been corrected to N. lithophilus. Included in this treatise are 71 color photographs including photos of male and female terminalia, male genitalia, and two species of larvae. Key words.

Se reconocen nueve especies de Navasoleon (Neuroptera: Myrmeleontidae: Nemoleontini) con las des- cripciones de seven especies nuevas: N. amazonas Stange, N. brasiliensis Miller, N. egeri Stange, N. lithophilus Miller, N. lotti Stange, N. tarsalis Miller, y N. venezolanus Stange. Se designa a Navasoleon bosqui (Navás) como nomen dubium. Se presenta una clave para las nueve especies y para las larvas además para los generos de Nemoleontini con uñas prensiles. Se provee una diagnosis para las especies además de datos sobre distribución geográfica. Se describen las larvas de dos especies con observaciones biologícas. Datos biológicos en el trabajo de Miller and Stange (1985), erroneamenta asignado como N. bolivianus (Banks), ahora corrigido a N. lithophilus. Se incluye 71 fotos de color, incluyendo fotos de las terminalias de los machos y hembras, las genitalias de los machos, y las larvas de dos especies. Palabras clave.

Introduction The genus Navasoleon Banks differs from all other new world groups of antlions by having the foreleg elongate, usually much longer than the hindleg and midleg. The pretarsal claws can close against the setal brush on the ventral surface of the distal tarsomere. This South American genus is unusual as the larvae live on bare rock (Miller and Stange 1985). The larvae are ascalaphid-like in appearance, with abdominal scolus-like processes and with the mandibular teeth placed distally. Nine rather uncommonly collected species are known and are classified in three species groups based on leg structure, wing vena- tion and female terminalia. The species appear to have restricted distributions suggesting that more species will probably be found in other areas. Descriptions and keys to the species are provided as well as biological notes. Also, a key to the genera of Nemoleontini with folding pretarsal claws is provided. Materials and Methods Adult terminology is based on Stange (1970a) and larval terminology on Badano and Pantaleoni (2014). Larvae were preserved in 75 percent ethanol after treatment with KAAD larval fixative (solution made from kerosene, ethyl alcohol, glacial acetic acid and dioxane). A machinist’s caliper was used to 2 • INSECTA MUNDI 0619, April 2018 STANGE AND MILLER make measurements of adult wings and body length. Most photos of larvae were made from preserved specimens, which lack the natural coloration seen in live material. Photographs of adults and larvae 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. Images of adult antlions were cap- tured from pinned specimens. Male genitalia, after clearing in KOH and dissection, were photographed under ethanol submerged cover slips to prevent movement. After study and photographs, the genitalia were stored in microvials in glycerin associated with pinned specimens. Female terminalia, after clear- ing in KOH, were placed in petri dishes and covered with a microscope slide, where they were then photographed after correct positioning had been achieved. Preserved larvae were photographed under ethanol submerged microscope slides. Photographs were electronically enhanced and cleaned up using the Picasa program. Use of this program on terminalia was found to bring out visual contrast
