Abstract

The genus Frontiniella Townsend is transferred from the Eryciini to the Goniini, based on the production of microtype eggs in adult females. Frontiniella is known only from the Nearctic Region and the northern extreme of the Neotropical Region. Eufrontina Brooks is newly synonymized with Frontiniella and all species formerly placed in that genus are transferred to Frontiniella. Frontiniella is hypothesized to be monophyletic based on two derived character states: long hairs on the male surstylus, and elongate posterior spiracles on the puparium. Two species groups are recognized, one with six species and the other with four: the parancilla-group with F. parancilla Townsend, F. incarcerata sp.nov. (type-locality Hwy. 366, Graham Co., Arizona, USA), F. spectabilis (Aldrich) (new combination), F. surstylata sp.nov. (type-locality near Olustee, Florida, USA), F. jorgenseni sp.nov. (type-locality 20 miles northwest of Kenna, New Mexico, USA), and F. ethniae (Brooks) (new combination); and the festinans-group with F. festinans (Aldrich and Webber), F. apache sp.nov. (type-locality Sulphur Draw, Chiricahua Mts., Arizona, USA), F. mitis (Curran), and F. regilla (Reinhard). This revision includes a key to the 10 known species of Frontiniella, a description of each species (including puparium where known), maps of species distributions, an annotated list of hosts (including corrections to previously published records and additions from material examined), and illustrations of taxonomically useful features.

Résumé

Le genre Frontiniella Townsend est transféré de la tribu des Eryciini à celle des Goniini parce que les femelles adultes produisent des oeufs très petits. Frontiniella n’est connu que de la région néarctique et de l’extrême nord de la région néotropicale. Eufrontina Brooks devient synonyme de Frontiniella et toutes les espèces qui appartenaient à ce genre sont transférées au genre Frontiniella. Frontiniella est probablement un genre monophylétique à cause de deux caractères dérivés : longs poils sur le surstylus du mâle et stigmates postérieurs allongés sur le puparium. Deux groupes d’espèces sont reconnus, l’un contenant six espèces, l’autre quatre : le groupe parancilla comprend F. parancilla Townsend, F. incarcerata sp.nov. (localité type, Route 366, Co. Graham, Arizona, É.-U.), F. spectabilis (Aldrich) (nouvelle combinaison), F. surstylata sp.nov. (localité type, près d’Olustee, Floride, É.-U.), F. jorgenseni sp.nov. (localité type, 20 milles au nord-ouest de Kenna, Nouveau-Mexique, É.-U.) et F. ethniae (Brooks) (nouvelle combinaison); le groupe festinans comprend F. festinans (Aldrich et Webber), F. apache sp.nov. (localité type, Sulphur Draw, monts Chiricahua, Arizona, É.-U.), F. mitis (Curran) et F. regilla (Reinhard). Cette révision contient une clé d’identification des 10 espèces connues de Frontiniella, la description de chaque espèce (et du puparium lorsqu’il est connu), des cartes de répartition des espèces, une liste annotée des hôtes (y compris des corrections aux mentions publiées et des additions), et des illustrations des caractéristiques taxonomiques diagnostiques.
