Abstract

Oxyptilus eleanerae sp. n., is described from New Mexico, Arizona, and Southwest Texas, and compared with the only other Oxyptilus occurring in the Nearctic Region, O. delawaricus Zeller. A redescription is provided for O. delawaricus. Adults and male and female genitalia are illustrated for both species. Key morphological characters, distributions, and relationships within the genus are discussed.

Highlights

The genus Oxyptilus Zeller formerly included 28 species worldwide (Gielis 2003)
The 2016 donation of the Texas Lepidoptera Survey collection to the McGuire Center by Ed Knudson and the late Charles Bordelon yielded six more specimens from the Davis Mountains. This new species was confirmed as a “true Oxyptilus” through key characters in Alipanah et al (2010) and is described and distinguished from O. delawaricus
Specimens examined for this study, including comparative material of O. delawaricus, are from the following institutions and private collections: Academy of Natural Sciences of Philadelphia (ANSP); Deborah Matthews Collection, Gainesville, Florida (DMC); Canadian National Collection, Ottawa (CNC); Great Lakes Forestry Centre, Sault Ste

Summary

Introduction

The genus Oxyptilus Zeller (type species Pterophorus pilosellae Zeller) formerly included 28 species worldwide (Gielis 2003). The five “true Oxyptilus”, including the Nearctic species, O. delawaricus, are associated with the composite genus Hieracium as larval hosts (Gielis 2003, Matthews and Lott 2005). The 2016 donation of the Texas Lepidoptera Survey collection to the McGuire Center by Ed Knudson and the late Charles Bordelon yielded six more specimens from the Davis Mountains. This new species was confirmed as a “true Oxyptilus” through key characters in Alipanah et al (2010) and is described and distinguished from O. delawaricus. CO1 barcodes from two USNM specimens further support the distinct identity and placement within the genus
