Ancistrocerus trifasciatus

description: Ancistrocerus trifasciatus (Müller, 1776)
(Figs 1C, D, F, H; 2C, D, G, H)
Vespa trifasciata Müller, 1776: 163 (type locality: “Daniae et Norvegiae” [Denmark and Norway]); type depository unknown.
? Vespa trifasciata Fabricius, 1787: 290 (type locality: “Habitat Hafniae” [Denmark]), nom. praeocc., nec V. trifasciata Müller, 1776; syntype (s), ♀, Natural History Museum Denmark, Uniersity of Copenhagen, Copenhagen, Denmark.
Odynerus trimarginatus Zetterstedt, 1838: 456, ♀ ♂ (type locality: “Lapponia … (Lappon.-Uplandia; Gotlandia pass.)” [Finland]); syntypes, Lund University, Sweden.
Odynerus tricinctus Herrich-Schäffer, 1839: 20, [♀] (type locality not indicated, probably Germany), 1841: pl. 10; type material destroyed.
Differential diagnosis. Females of this species can be distinguished from the closely related A. shibuyai by S 2 in lateral view weakly convex to nearly flat (Fig. 1F; vs. distinctly convex in A. shibuyai, Fig. 1E). Males can be distinguished by ventral lobe of the aedeagus apically rather triangularly pointed (Fig. 1H; vs. rounded in A. shibuyai, Fig. 1G). An additional character is the coloration of the hind tibia: usually with extensive brown and yellow pattern in the female (Fig. 2C) (very rarely completely or near completely black, Fig. 2D) and usually almost entirely yellow in the male (Fig. 2G) (very rarely black dorsally, particularly in specimens from Kamchatka, Fig. 2H). Other characters mentioned in the key by Budrys et al. (2023, Supplement 3) can be also applied but they are also variable and therefore less diagnostic.
Remarks. We follow the traditional treatment of A. trifasciatus (Blüthgen 1961; Budrys et al. 2023) and its synonymy (Blüthgen 1938, 1961; van der Vecht & Fischer 1972), except that A. trifasciatus moeschleri is treated here as a synonym of A. shibuyai (see above). It is, however, unclear from the original description of Vespa trifasciata Müller, 1776 if it was the same species as commonly known at present as A. trifasciatus, or the species known at present as A. shibuyai. Since the type depository of V. trifasciata Müller, 1776 is unknown (van der Vecht & Fischer 1972), the type material can be actually lost and we cannot clarify its diagnostic characters. In our opinion, a neotype should be designated to keep nomenclature stability (Art. 75.3 of ICZN 1999) but we do not have examined any specimen from the type locality (either Denmark or Norway). Such a specimen should be corresponding to the traditional treatment of A. trifasciatus (Blüthgen 1961; Budrys et al. 2023; present paper) and, since A. trifasciatus and A. shibuyai can be easily distinguished by DNA barcoding (Budrys et al. 2023), the COI-5P gene of a possible neotype should be barcoded prior to its designation (cf. Selis et al. 2023).
The name V. trifasciata Fabricius, 1787 is also doubtful due to a lack of the description of important characters in the original publication. However, this name is anyway permanently invalid due to the homonymy with V. trifasciata Müller, 1776 (Art. 57.2 of ICZN 1999). As for the names Odynerus trimarginatus and O. tricinctus, their descriptions are enough to clarify their conspecificity with A. trifasciatus (in its traditional treatment) due to the leg color specified (Zetterstedt 1838) or even illustrated (Herrich-Schäffer 1841).
It is also to be noted that in Gusenleitner’s (1995) paper, fig. 4 labeled as A. trifasciatus actually depicts A. oviventris (Wesmael, 1836), while fig. 5 labeled as A. oviventris depicts rather A. shibuyai than A. trifasciatus.
