ABSTRACT

Codatractus valeriana (Plötz, 1881) comb. nov. is confirmed as a senior synonym of Thorybes mysie Dyar, 1904. A lectotype for Eudamus valeriana Plötz is designated.

Key words: Nearctic, Neotropical, taxonomy, type specimen.


 

 

The examination of type specimens of various Hesperiidae in European museums by the senior author has resulted in many recent changes in the synonymies of the Neotropical and Nearctic species (MIELKE & CASAGRANDE 2002). This note concerns identity of Eudamus valeriana Plötz, 1881; its syntype specimen was examined by the senior author in 1979 at the "Museum für Naturkunde der Humboldt Universität" in Berlin, Germany.

The true identity of Eudamus valeriana has been confused in recent decades. Being a species reported from the United States of America, it has been mentioned in many Nearctic publications, even though its identity has been uncertain (see BURNS 1996 for a review). EVANS (1952) treated Thorybes mysie Dyar, 1904 as a synonym of T. valeriana, and this arrangement was generally followed (MILLER 1970, MACNEILL 1975, MILLER & BROWN 1981, SCOTT, 1981, 1986) until BURNS (1996) reviewed the "cyda group" of Codatractus, and concluded that T. mysie was a species of Codatractus, and that it was not conspecific with E. valeriana. BURNS' conclusion that mysie and valeriana are not conspecific was based on differences in the structure of the antennal club and apiculus, as well as of the wing pattern, shown by the lectotype of T. mysie and an unpublished painting supposedly of the type of E. valeriana. Since 1996, Codatractus mysie has been recognized as part of the fauna of the United States of America, and E. valeriana has been excluded from the Nearctic fauna (OPLER & WARREN 2002). However, the true identity of valeriana was not revealed by BURNS (1996), and the taxon has therefore remained in Thorybes until now (MIELKE, in press).

BURNS' (1996) conclusions were based on an unpublished color painting (subsequently published by BURNS 2001), supposedly of the type specimen of E. valeriana, housed at "The Natural History Museum" in London, England. However, BURNS (1996) did not mention the existing syntype specimen of E. valeriana in Berlin, and apparently, all efforts he may have made to locate the syntype specimen were unsuccessful. Once the syntype specimen of E. valeriana is known to exist, the conclusions made by BURNS (1996, 2001) based on a color painting supposedly of the type, are irrelevant.

The syntype of Eudamus valeriana (Figs 1, 2) is clearly conspecific with T. mysie (see illustrations of lectotype of T. mysie in BURNS 1996: 208). The two taxa share the same details of antennal structure (note that the club of the left antenna of the syntype of E. valeriana is broken), and agree in all details of wing markings. The painting of E. valeriana in the "The Natural History Museum", London (a copy of PLÖTZ'S original unpublished figures), examined by BURNS (1996, 2001) is clearly a very poor and inaccurate reproduction, if it is even of the syntype of valeriana. With the true identity of Eudamus valeriana revealed, based on the examination of a syntype specimen, the following synonymy is proposed.

 

 

Codatractus valeriana (Plötz, 1881), comb. nov.

Eudamus valeriana Plötz, 1881. Stett. ent. Ztg. 43: 99; number 5050, Mexico; Mus. Berol.

Thorybes mysie Dyar, 1904. Jour. N. Y. Ent. Soc. 12: 40; 2 males, numbers 7,737, Patagonia Mountains, Arizona, [USA], E. J. Oslar leg., USNM.; confirmed synonymy.

Codatractus mysie; Burns, 1996. Jour. Lep. Soc. 50: 197, 198, 199, 203, 210, figs 52, 53 (genitalia male), 59, 60 (genitalia male), 66, 67 (genitalia male), 73 (genitalia female), 79, 80 (male dorsal, ventral), 93 (geographical distribution); Lectotype male, USNM.

PLÖTZ (1881) did not state explicitly in his original description of C. valeriana that he was basing that name on a unique specimen ("Mus. Berol n. 5050" might be interpreted as meaning a series of specimens in the Berlin Museum); therefore the "type" in Berlin should be regarded as a syntype. This syntype of Eudamus valeriana Plötz, 1881 has the following labels: /5050/ Typus/ Mexico Friedr./ valeriana Pl. type/; there is no abdomen. To preserve stability of nomenclature, this specimen is here designated Lectotype, and an appropriate label will be added.
