Abstract
Lacconotus LeConte, the sole Nearctic representative of the eurypine Mycteridae, is revised, based on morphological features of adults. The following syn. n. is proposed: Lacconotus pallidus Van Dyke, 1928 = Lacconotus pinicola Horn, 1879. The former is a light-colored form with a southern California distribution. A subgen. n., Alcconotus, is described for Lacconotus pinicola, producing the following comb. n.: Lacconotus (Alcconotus) pinicola (Horn). A lectotype is designated for Lacconotus pinicola. A key separating the two subgenera and species is provided, as are photographs and illustrations of salient structures of adults, and maps showing collection localities. Lacconotus punctatus is newly recorded in Alabama, Arkansas, Massachusetts, Oklahoma, Texas, and Wisconsin; Lacconotus pinicola is newly recorded in Arizona and Utah in the USA, and Baja California Norte in Mexico. Phenology information shows a north-to-south gradation in occurrence time.
Highlights
Among the three subfamilies of Mycteridae, the Eurypinae (= Lacconotinae) are the most diverse with 26 genera and 160 species recognized worldwide, the greatest diver-Copyright D
The Nearctic fauna of Mycteridae is not large, but represents all three subfamilies: six species of Mycterus Clairville (Mycterinae), three species of Hemipeplus Latreille (Hemipeplinae), and two species of Eurypinae. The latter are represented by Lacconotus punctatus LeConte and L. pinicola Horn (= L. pallidus Van Dyke)
Lacconotus punctatus is newly recorded in Alabama, Arkansas, Massachusetts, Oklahoma, Texas, and Wisconsin
