03FF186B1640FFCFFDFAA9C1FB114CBB.taxon	discussion	Remarks The lectotype of Haltica amicta is designated here to be the unique bearer of this name and the standard for its application. The lectotype is intact. The species does not belong in Oedionychini, but rather Disonychini LeConte & Horn, 1883, by the absence of a globosely swollen apical metatarsus and a strongly defined frontal ridge. We here place it in the genus Phenrica Bechyně, 1957, because of the smaller size and eye formation. It is similar to the type of Phenrica quadrimaculata (Clark, 1865) in the BMNH and could very well prove to be conspecific (Michael Geiser, pers. comm.).	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.

The lectotype is missing right antennomeres VI – XI, as well as the left front leg. We confirm the correct placement in the genus Alagoasa based on the following characters: frontal ridge narrow, vertex with a few punctures, sides of pronotum widely explanate, body broadly ovoid, apical metatarsus globosely swollen (see also Konstantinov et al. 2022). This species was synonymized with Alagoasa dissepta (Erichson, 1847) by Bechyně (1955 a: 210) and considered a variation of A. dissepta. However, clear morphological differences like the shape of the anterofrontal ridge, shape of anterofrontal angles of pronotum, and lateral pronotal edge set it apart from A. dissepta.	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.

Probably unaware of this, Bechyně & Bechyně (1977: 122) treated A. dipus as a distinct species, consequently restoring species status. However, examination of both the type specimens of A. decemguttata (Van Roie et al. 2024: 22 – 25) and A. dipus did not show any meaningful differences between the two species apart from slightly darker elytropleura in A. dipus.

03FF186B1653FFD8FDA9AD8DFC204C4B.taxon	discussion	Remarks The lectotype of Oedionychis florigera is designated here to be the unique bearer of this name and the standard for its application. The lectotype is intact. While the original description does not mention any variations, the labels on the varieties in the collection are of a similar style and / or handwriting as other type material. Moreover, in the MFNB catalog, under the corresponding label numbers, these specimens are indicated by a type asterisk. We thus decided to consider these as paralectotypes, where the variations are intrasubspecific. For aiding future identifications, we figured these variations as well (Fig. 10). We confirm the correct placement in the genus Alagoasa based on the following characters: frontal ridge narrow, vertex with a few punctures, sides of pronotum widely explanate, body broadly curved, apical metatarsus globosely swollen (see also Konstantinov et al. 2022).	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.

This species is included in Bechyně’s unpublished catalog under the genus Asphaerasta, which is a nomen nudum, i. e., Bechyně never published the description of this genus. Indeed, the present species probably needs to be placed in a new genus, but study of the other species included in Bechyně’s nomen nudum is advised before doing so.	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.

The lectotype is missing all left metatarsomeres, all left protarsomeres, right protarsomeres II – V, and left antennomeres IV – XI. The specimens are not obvious syntypes but do conform with the description in being from Nova Friburgo (Brazil) and from the Schaufuss collection. The “ Type ” label does resemble Harold’s handwriting, although we are not completely sure. We consider them to be probable syntypes and therefore designated the lectotype. The specimens miss the tooth-like structured prosternal process as characteristic for the genus, but since these are females (and this structure is most apparent in males), this cannot reliably be determined for the species.

The lectotype is intact. Haltica sexmaculata is the type species of the genus Capraita. Species of the genus Capraita have the following characteristics: presence of an antebasal depression on the pronotum, a flattened prosternal projection, and a tendency to have smaller eyes (Bechyně & Bechyně 1977). The locality indicated on the label is ‘ America Septentrionalis’, possibly indicating the U. S. A. or Canada. However, Illiger gives ‘ Pensylvanien’ in the original description, pointing to the U.

The lectotype is intact. The specimen does not bear a type label, but the first label specifically denotes the collector Olfers (as ‘ Olf. ’) as indicated in the original description. Additionally, after the original entry in the original description, Harold (1881) writes “ Mus. Berol. No. 5034 ”, corresponding with the numbered label under the specimen. Indeed, in the MFNB written catalog, number 5034 corresponds with the entry ‘ taeniolata Harold, Brasil, v. Olfers’. We can thus rightfully assume this specimen is the syntype. We place this species in Capraita based on the following characteristics: pronotum with a prebasal transverse impression, wide and flattened intracoxal process, and relatively small eyes (see Konstantinov et al. 2022).	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.

The lectotype is missing right antennomeres VII – XI and left antennomeres X – XI, as well as right metatarsomeres III – V. The original description does not state the type locality, but states “ Vaterland ” instead. Vaterland is a German word that can be interpreted as ‘ home country’. We suspect that this might be an error in the manuscript, serving as a place marker for the type locality. Although the type locality was not stated, we do consider the current specimens as the lectotype and paralectotype because the label is of the same handwriting and format as other species of Illiger and is denoted with an asterisk.

The lectotype is missing left antennomeres II – XI as well as the left front leg. Although the type bears a label stating “ holotype ”, the original description does not state the existence of a specific holotype, nor the number of specimens (excluding holotype fixed by monotypy). We could also not find a publication discussing the type of O. fairmairei. We thus treat the specimen as a syntype and consequently designate the lectotype. We confirmed the placement of this species in Kuschelina based on the following characters: eyes small, diameter of eye three times narrower than the frons, head strongly punctuated, moniliform antennae, epipleura slanted downward, thus visible in lateral view, antero-lateral corners of pronotum slightly protruding, and body elongate to oval (Bechyně 1951; Furth 2017; Konstantinov et al. 2022).

03FF186B160FFF86FDA5AC5EFCB348F6.taxon	discussion	Remarks The lectotype of Homophoeta clerica is designated here to be the unique bearer of this name and the standard for its application. The lectotype is missing right antennomeres VI – XI. The species is currently placed in the genus Omophoita. Although it is not conforming entirely with other species in the genus, the thickened anterolateral angles of the pronotum, together with the labrum bearing more than 4 irregularly placed setae, speak in favor of Omophoita. Future studies should evaluate its placement. The species is clearly related to Omophoita t-album (Harold, 1876).	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.

We confirm the placement of this species in Omophoita based on the following characters: anterolateral corner of pronotum with lateral side straight, projecting directly forward, thickened, intercoxal prosternal process narrow (see also Konstantinov et al. 2022). There has been considerable confusion about the identity of Omophoita lunata sensu Olivier and Alagoasa lunata sensu Fabricius. Olivier (1808) actually seemed to establish a new combination for Galleruca lunata Fabricius, 1801 to Altica lunata (Fabricius, 1801) but probably confused specimens now known as Oedionychis longicollis Schaufuss, 1874 with the former. This also led to the synonymisation of Omophoita longicollis (Schaufuss, 1874) with Alagoasa lunata (Fabricius, 1801). Since then, the name lunata has been given to the species now named Omophoita longicollis. However, examination of the Fabrician type of Galleruca lunata by Konstantinov et al. (2022) and later Van Roie et al. (2024) revealed that Galleruca lunata belongs in the genus Alagoasa and is clearly different from the present species that belongs in Omophoita. We thus restore its species status.	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.

03FF186B1623FFA8FDF8ADB7FE2C4EE6.taxon	discussion	Remarks One specimen in the MFNB collections bears an identification label of Oedionychis ophthalmica Harold, clearly written by Harold himself (Horn et al. 1965; Cupello 2020, 2021; Cupello pers. comm.). Moreover, the specimen bears a locality label “ Pozuzu ”. As indicated in the introduction of Harold’s (1877) paper, the specimens he based his descriptions on were collected by Ernst Robert Abendroth in the “ Pozuzu Valley ” (nowadays called Pozuzo, Peru). It is possible that Abendroth may have split his series among different entomologists, with some specimens going to Kirsch (who, according to the same introduction, provided Harold with the Pozuzo material) and others possibly going to Schaufuss. In fact, both Abendroth and Schaufuss were based in Dresden at that time. Following the same train of thought, perhaps Harold was only able to study this specimen afterwards, supported by the fact that no indication on the label hints towards the specimen being part of the type series. We thus consider this specimen to be a potential syntype, lacking sufficient evidence to justify a lectotype designation. Given the original description, the current specimen conforms with “ Var. b. ”, although the elytral markings may be somewhat lighter than the description suggests. The specimen holds strong value, though, since it is from the same locality as the (not yet located) type, and was identified by Harold himself. The specimen belongs in the genus Walterianella based on the following characters: eyes large, interocular space about as wide as the diameter of the eye, pronotal borders widely explanate, flattened, prosternal process keeled (see Konstantinov et al. 2022).

03FF186B1621FFA8FDD8AD6CFEFD493A.taxon	discussion	Remarks The lectotype of Haltica paupera is designated here to be the unique bearer of this name and the standard for its application. The lectotype is missing right antennomeres IV – XI, as well as all left metatarsomeres. The species is currently included in Walterianella. It shares characteristics with Walterianella, such as the relatively large eyes, explanate pronotal disc, and slender antennae. However, some characteristics set it apart from the typical Walterianella, such as the anterolateral pronotal angles pointing laterally and a more flattened prosternal process. Future studies should evaluate the placement of this species in Walterianella.	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.

Examination of the types and the male aedeagi only showed minor morphological differences. Particularly, the size of red spots on the elytra differed; however, falling within the natural variation of the species. We here consider Walterianella quadripunctata a new synonym of Walterianella venustula (Schaufuss, 1874). Both species were described in the same publication (Schaufuss 1874) and are therefore of equal date. According to Article 24.2 of the ICZN, precedence between such names is fixed by the First Reviser.

03FF186B162FFFA6FE20AE2FFC6949F2.taxon	discussion	Remarks The lectotype of Oedionychis punctulata is designated here to be the unique bearer of this name and the standard for its application. The lectotype is missing the right antenna. The species was placed in Alagoasa, but we place it in Wanderbiltiana because of its similarity with other Wanderbiltiana species (Van Roie et al. unpublished data) and the following characters: head elongate, elytra finely punctate, elongate, not strongly rounded, apical metatarsomere globosely swollen. Especially the elongate head seems to set it apart from Alagoasa, but more study is certainly needed. Corrections and additions to Van Roie et al. 2024 In our previous paper, we erroneously placed Galleruca obsoleta Fabricius, 1801 in the genus Phenrica (Van Roie et al. 2024: 41). However, the species belongs in the genus Heikertingeria Csiki, 1940 (Michael Geiser pers. comm.). We thus hereby rectify our mistake and propose Heikertingeria obsoleta (Fabricius, 1801) as a new combination. The species Galleruca avicenniae Fabricius, 1792, which we removed from Oedionychini and placed in incertae sedis Galerucitae Latreille, 1802, has since then been confirmed to belong in the genus Asbecesta Harold, 1877 (Michael Geiser and Ron Beenen pers. comm.). We thus hereby propose Asbecesta avicenniae (Fabricius, 1792) as a new combination. Moreover, it is a senior synonym of Asbecesta cyanipennis Harold, 1877, new synonymy (Ron Beenen pers. comm.).	en	Van Roie, Martijn, D'Hont, Anouk, Konstantinov, Alexander (2026): Types of New World Oedionychini Chapuis, 1875 (Coleoptera, Chrysomelidae, Galerucinae, Alticitae) deposited in the Museum für Naturkunde, Berlin.
