Box 141874 Gainesville, FL 32614-1874 USA 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, nomencla- ture, 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 re- views 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 Abstracts, etc. Insecta Mundi is published irregularly throughout the year, with completed manu- scripts 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 manu- script must be a current member of the Center for Systematic Entomology. Manuscript preparation guidelines are availablr at the CSE website.

A new species of Paranthaclisis Banks, P. floridensis (Neuroptera: Myrmeleontidae), is described from Florida and compared to the other described species in the genus. Keys to the adults and larvae are provided. Resumen. Se describe una nueva especie de Paranthaclisis Banks, P. floridensis (Neuroptera: Myrmeleontidae), de Florida y se la incluye en una clave para las otras especies descriptas del género. Se da una descripción del adulto y de la larva. Introduction The presence of Paranthaclisis Banks (Neuroptera: Myrmeleontidae) in Florida was first noted by Hagen (1887) who described a one-toothed larva from Florida which must belong to this genus since no other larvae known from the New World have only one tooth on the mandible. We have discovered a new species of this genus on the northern coastal beaches of Florida . To date, five adult specimens of this species of Paranthaclisis have been collected in Florida. Also, the larva has been found and reared. Materials Specimens studied are deposited in the following institutions: FSCA - Florida State Collection of Arthropods, Gainesville, Florida, U.S.A.; USNM - Smithsonian Institution, Washington, D.C., U.S.A. Paranthaclisis Banks 1907: 275 Type species: Acanthaclisis congener Hagen, by subsequent designation of Banks 1927: 80 as “P. conge- ner (Hagen)”. Key to species: Banks 1927: 80, Banks 1939: 5. Distribution: Mexico (Baja California); U.S.A. (Arizona; California; Florida; Nevada; New Mexico; Oregon; Texas; Utah). Further description: Banks 1927: 79; Stange and Miller 1985: 36. Larva: Hagen 1887: 151; Stange and Miller 1985: 36, Figures 1, 6 (larva). Further description: Banks 1927: 79. Diagnosis. Adult: ocular rim with short white setae that project over eye; distal palpomere with elon- gate palpomacula not reaching to apex; pronotum wider than long; all femora with one elongate sense hair; pretarsal claws strongly bent with flange, shorter than tibial spurs which are bent at nearly a right angle; forewing costal area narrowing toward apex, usually simple (except in P. floridensis); forewing with anterior Banksian line; hindwing vein CuA not fused with posterior fork of MP2; abdomen with pair of eversible sacs between tergites VI and VII (except P. nevadensis). Larva: head capsule with anterior margin of clypeo-labrum weakly sinuate; ventral surface of head capsule nearly glabrous; length of antenna shorter than basal width of mandible; mandible with one blunt tooth; hind pretarsal claws 1 2 • INSECTA MUNDI 0224, April 2012 STANGE AND MILLER very thick, less than twice as long as basal width, shorter than mid-pretarsal claws which are several times longer than wide; mid-tarsus longer than mid-tibia and nearly as wide basally as tibia apically; sternite VII with many short, peg-like digging setae, area of digging setae more than five times longer than wide. Biology. Female Paranthaclisis congener were observed (Stange and Miller, 1985) to lay eggs at dusk near Reno, Nevada. As the female expels the eggs, she evenly coats them with sand, using the posterior gonapophysis. The eggs are buried up to one quarter or more of the abdominal length and the larval head capsule is fully hardened prior to hatching, in contrast to other known non-acanthaclisine ant-lions which lay their eggs on the surface and in which the larva hatches on the surface with the head capsule and mandibles soft, having been folded into the egg, and ready to expand upon being freed of the egg and exposed on the surface. Eggs of Acanthaclisini are laid in batches of twenty and hatch in about 24 days. There are three instars. The larvae prefer deep sand and can move both forward and backward rapidly but observations to date indicate that the larvae do not pursue prey on the sand but rather dig rapidly backward after the prey and grab the prey by whipping their head backward after they are underneath it. Prey observed to date have been lepidopterous larvae and many types of sand roaming adult Coleoptera. Discussion. Paranthaclisis Banks is a Nearctic genus which contains four species. The hindwing vena- tion of Paranthaclisis is distinctive in the tribe since CuA does not unite with MP2 as in other genera. The larva is also very distinctive in having only one mandibular tooth. Paranthaclisis nevadensis Banks lacks eversible sacs on the abdomen of the male. This strictly Nearctic genus Paranthaclisis belongs to the tribe Acanthaclisini of the subfamily Myrmeleontinae and is restricted in distribution to the temper- ate areas of North America. The Acanthaclisini is characterized by the presence
