2.3. Taxonomie und Faunistik

Plötz (1883: 230) konnte in seiner Erstbeschreibung nur mitteilen: "Vaterland ?" - er wusste also nicht, woher das Tier, das er beschrieb, stammte. Da Tiere mit dem entsprechenden Genmaterial sonst auf Java gefunden wurden, gehen Zhang et al. (2026: 123-124) fest davon aus, dass das auch der Typenfundort sein müsste - zumal es bisher keine Funde von außerhalb Javas gibt: "Genomic analysis of Potanthus Scudder, 1872 (type species Hesperia omaha Edwards, 1863) places the lectotype of Hesperia euria Plötz, 1883 (type locality not stated; sequenced as NVG-21117H07) among specimens from Indonesia: Java (Fig. 95 blue) and away from the clade of specimens from Indonesia: Sumatra (Fig. 95 red). Pamphila orfitus Mabille, 1883 (published in May) (type locality in Indonesia: Java), the name currently applied to populations from Java, is junior to H. euria Plötz, 1883 (published in mid-January). Therefore, we propose that Pamphila orfitus Mabille, 1883, syn. nov. is a junior subjective synonym of Potanthus (Potanthus) euria (Plötz, 1883). Evans (1949) misapplied the name P. euria to populations in Sumatra (misidentification), with Padraona pavor De Niceville, 1894 (type locality in Indonesia: northeastern Sumatra, Batak Mountains) (Fig. 94b) being treated as its junior subjective synonym. The lectotype designation suggests synonymy of P. euria and Pamphila orfitus, and not of P. euria and Padraona pavor. Once P. euria is restricted to the Javan taxon, the senior available name for populations in Sumatra is Padraona pavor. Moreover, genomic comparison reveals species-level genetic differentiation between populations in Java and Sumatra (Fig. 95); e.g., their COI barcodes differ by 7.0% (46 bp)."

Chiba et al. (2026: 514) schrieben: "We further note that the species Evans (1949) misidentified as P. fettingi is Potanthus euria (Plötz, 1883) (published in January) (Fig. 3 green), as catalogued by Bridges (1994), which is the oldest name that applies to this species. Finally, we note that Evans (1949) gave an incorrect date (1874, apparently a lapsus) for Pamphila orfitus Mabille, 1883, described during the same year as Hesperia euria, but in May." Auch Zhang et al. (2026: 122-123) kamen zum Schluss, dass P. orfitus Mabille (1883) ein um 4 Monate jüngeres Synonym von P. euria ist.

2.4. Typenmaterial

Zhang et al. (2026: 122-123) legen den Lectotypus fest und vermerken dazu: "In the MFNB, we found a specimen originally from Weymer’s collection labeled “Euria Wmr |i.l.” in Weymer’s handwriting, with “i.l.” standing for in litteris (literally meaning “in letters” or “in correspondence”) usually added to yet unpublished names. Moreover, according to one of its labels, it was identified by Plötz as “Euria Wmr i.l.” and is lacking a locality label; thus, its provenance was likely unknown. This specimen matches the original description, was collected prior to its publication, dated 1877, and is a syntype of H. euria. To define the taxonomic identity of the name H. euria objectively, N.V.G. hereby designates this syntype in the MFNB collection, a male illustrated in Fig. 94a bearing the following six rectangular labels (the last two printed, others handwritten): [ 77 v. Heyne ], [ Euria Wmr. i.l. | no 317 best. v. Plötz ], [ Euria Wmr | i. l. ], [ 317 | Weymer ], [ Coll. Weymer ], and [ DNA sample ID: | NVG-21117H07 | c/o Nick V. Grishin ], as the lectotype of Hesperia euria Plötz, 1883. The first four labels are in Weymer’s handwriting. According to the first label, the specimen was received from (or collected by?) Heyne in 1877. According to the second label, this specimen was identified by Plötz (“best[immt]. v[on]. Plötz”) as “Euria Wmr.”, and this label with the name was added to the specimen prior to publication (“i[n].l[itteris]”). The number 317 is likely an unpublished specimen number in the Weymer collection, or the number of a specimen among those identified by Plötz. There is no locality stated on the labels. The lectotype is missing the left antenna, and its right hindwing is torn near the inner margin from the base and at the outer margin. The type locality of H. euria is in Indonesia: Java, as inferred by genomic comparison of the lectotype with specimens from known localities (Fig. 95). The COI barcode sequence of the lectotype, sample NVG-21117H07, GenBank PZ516436, 658 base pairs, is [...]"
