03C2CE00FFFEFF9C3EFA0E57FBA64363.taxon	description	The BI, ML and MP analyses provide unequivocal support for the monophyly of Cerasommatidia clade and, therefore, we propose the restoration of family status for Cerasommatidiidae. Cerasommatidiidae are divided into four clades corresponding to the four genera proposed here (Fig. 2). The new monotypic genus from Madagascar, MahaƲelo, is recovered as sister-taxon to the Neotropical, type genus of the family, Cerasommatidia (= Ibicarella, synon. nov.), albeit with weak support (PP = 0.83). Morphologically, both genera share the labial palp with oval, inflated second palpomere (12: 1). MahaƲelo is characterized by one uncontroverted synapomorphy, scutellar shield invisible (25: 1) and one homoplastic feature, abdominal ventrite 1 without postcoxal lines (34: 0). Cerasommatidia is supported by one homoplastic character: mesotrochantin at least partially exposed (28: 0). Support for the clade comprising the new genera Yamuy and Karumbe is low (PP = 0.47) and lacks supporting morphological features. The new genus Karumbe is supported by the distinctly bordered pronotal base (19: 1) and pronotal anterior margin with bordering line crenulate (21: 1). Yamuy is characterized by a single uncontroverted synapomorphy, elytral vestiture comprising multiple setal forms (1: 1) and one homoplastic character, the abdominal ventrite 1 with postcoxal lines (34: 1).	en	Arriaga-Varela, Emmanuel, Tomaszewska, Wioletta, Szawaryn, Karol, Robertson, James, Seidel, Matthias, Ślipiński, Adam, Fikáček, Martin (2023): The resurrection of Cerasommatidiidae, an enigmatic group of coccinelloid beetles (Coleoptera: Coccinelloidea) based on molecular and morphological evidence.

03C2CE00FFFEFF933D8D0991FE114730.taxon	description	The results from our molecular (Fig. 1), morphological (Supporting Information, File S 12 a – c) and combined data (molecules and morphology) (Fig. 2) analyses strongly and unambiguously support the status of Cerasommatidiidae as a distinct clade at the family level. Morphologically, the monophyly of Cerasommatidiidae is supported by several characters (Fig. 2) (listed in Results) that set cerasommatidiids apart from Eupsilobiidae and other coccinelloid groups. In particular, the ovipositor lacking coxites is unique to this group and has not been found in any other Coccinelloidea. The sister-relationship of Cerasommatidiidae with Mycetaeidae is strongly supported in both the molecular and combined analyses. Yet, only one morphological, homoplastic character was recovered in the combined analyses as supporting this relationship: the mandible with subapical teeth or serrations (9: 0). At this point it is difficult to elucidate shared morphological characters between members of these two families. It is noteworthy that the position of Eupsilobiidae differs between the combined and molecular trees. In the molecular tree (Fig. 1) it is recovered as the sistergroup to Coccinellidae with strong support (PP = 1.0), whereas in the combined analysis it forms the sistergroup to the Mycetaeidae + Cerasommatidiidae, although with low nodal support (PP = 0.69) and no corresponding anatomical synapomorphies. The monophyly of Eupsilobiidae is supported by two uncontroverted synapomorphies: aedeagus with penis coiled (38: 1) and ovipositor with infundibulumlike structure / sperm duct modified (41: 1) and by one homoplastic character: labial mentum with large, triangular, raised area (11: 2). The position of Eupsilobiidae within the coccinellid group, as well as the internal family relationships, remains uncertain and ought to be readdressed in future studies. The genus Chileolobius, the only member of Eupsilobiidae represented in the molecular analysis, was supported in our combined data analysis as sister-group to the rest of Eupsilobiidae (‘ core Eupsilobiidae’ composed of Eidoreus, EƲolocera, Microxenus and Natalinus). This result could be an artefact of the remaining eupsilobiid exemplars being represented in the combined data analysis by morphological data only. However, Chileolobius is an enigmatic taxon, exhibiting several morphological features shared with all or some Coccinellidae but no other Eupsilobiidae, including frontoclypeal suture absent (6: 0), mandibular mola absent or reduced (7: 1) and mesotrochantin concealed (28: 1). The core eupsilobiids are recovered with strong nodal support (PP = 0.99) and multiple anatomical apomorphies, including antennae composed of ten articles (4: 2) and mesotrochantin at least partially exposed (28: 0). A closer relationship between Eidoreus and Microxenus, with respect to Chileolobius and Ibicarella, was previously hypothesized by Pakaluk & Ślipiński (1990). Including molecular data for exemplars of core Eupsilobiidae will be the next step to elucidate their relationships with Chileolobius and corroborate the position of Eupsilobiidae among the coccinellid group of families. The results of this study demonstrate the separation of Cerasommatidiidae from Eupsilobiidae, and justify the restoration of this lineage to family status. Cerasommatidiidae are corroborated by both high topological support as the sister-group to Mycetaeidae in the molecular and combined analysis and by their unique morphological features, as outlined above. The relationships between species of Cerasommatidiidae, as revealed by the morphological and combined analyses, justify the recognition of four genera despite an unclear relationship between them. Cerasommatidia in the new sense (including Ibicarella) is a homogeneous group, with species differing only in the structures of the male genitalia, the body proportions and the degree of development of the pronotal border. A sister-relationship recovered for Cerasommatidia + MahaƲelo is based on single homoplastic character: labial palp with palpomere 2 oval, inflated (12: 1) and is not strongly supported (PP = 0.83). Similarly, the sisterrelationship of Yamuy with Karumbe has negligible nodal support (PP = 0.47) and no morphological characters to bolster the relationship.	en	Arriaga-Varela, Emmanuel, Tomaszewska, Wioletta, Szawaryn, Karol, Robertson, James, Seidel, Matthias, Ślipiński, Adam, Fikáček, Martin (2023): The resurrection of Cerasommatidiidae, an enigmatic group of coccinelloid beetles (Coleoptera: Coccinelloidea) based on molecular and morphological evidence.

03C2CE00FFF0FF963D8509BBFE1E4633.taxon	discussion	Comment: When Pakaluk & Ślipiński (1990) described Ibicarella in Eupsilobiinae they were not aware of its resemblance to Cerasommatidia Brèthes, 1925. Subsequently, when the holotype of Cerasommatidia arroaei was rediscovered its resemblance with Ibicarella was noticed and served as basis for the synonymy of Cerasommatidiidae under Eupsilobiinae (Pakaluk et al., 1994). Nevertheless, in part due to the state of preservation of the holotype of C. arroaei, its morphology was not thoroughly studied and both Cerasommatidia and Ibicarella were retained as valid genera. In the present study, we carefully examined the morphology of the type material of all Cerasommatidia and Ibicarella species and, following the results of our morphological (Supporting Information, File S 12 a – c) and combined (Fig. 2) analyses, we consider both represent the same genus and Ibicarella Pakaluk & Ślipiński is considered a subjective junior synonym of Cerasommatidia Arrow.	en	Arriaga-Varela, Emmanuel, Tomaszewska, Wioletta, Szawaryn, Karol, Robertson, James, Seidel, Matthias, Ślipiński, Adam, Fikáček, Martin (2023): The resurrection of Cerasommatidiidae, an enigmatic group of coccinelloid beetles (Coleoptera: Coccinelloidea) based on molecular and morphological evidence.

03C2CE00FFE7FFBA3EAA0F98FD8E4732.taxon	diagnosis	Diagnosis: MahaƲelo is a distinctive genus in Cerasommatidiidae by the lack of a scutellar shield (Fig. 18 C, F), and by having the prosternal process provided with single, longitudinal, median carina (Fig. 18 D). In general appearance it is most similar to Cerasommatidia, sharing the glabrous appearance of pronotal and elytral surfaces (covered with tiny inconspicuous hairs), pronotum without internal sublateral carinae, and pronotal and elytral surfaces covered with single size punctae (Fig. 18 C, F). However, apart from its unique characters, MahaƲelo can also be separated from Cerasommatidia by having the pronotal hind angles with small, oblique indentation to receive the humeral corner of the elytron (Fig. 18 C) (absent in Cerasommatidia).	en	Arriaga-Varela, Emmanuel, Tomaszewska, Wioletta, Szawaryn, Karol, Robertson, James, Seidel, Matthias, Ślipiński, Adam, Fikáček, Martin (2023): The resurrection of Cerasommatidiidae, an enigmatic group of coccinelloid beetles (Coleoptera: Coccinelloidea) based on molecular and morphological evidence.

03C2CE00FFDAFFBF3F1A0D3FFDE44194.taxon	biology_ecology	Information about the biology of this group of beetles is scarce, but some data can be gleaned from the habitats and methods by which they were collected. Specimens of Yamuy and MahaƲelo species were mostly collected by sifting leaf litter. One specimen was collected directly from a slime mould fruiting body; another one from a flight intercept trap. These observations can indicate that with high probability, the food source of Cerasommatidiidae is various species of slime moulds or other fungi-like organisms. Cerasommatidiidae are also active fliers. The coarsely facetted eyes of all taxa indicate that they probably have a nocturnal lifestyle. Yamuy constratus was collected in rainforest habitat, Y. marginatus in sparse montane forest and MahaƲelo madagasus in dry spiny forest biotope at low elevation. That indicates that these beetles inhabit different types of forest habitat, both rainforests (Puerto Rico), as well as dry spiny forest (Madagascar), at a variety of elevations ranging from lowland (110 m) to montane areas (1350 m). Although incomplete, this information can help locate additional habitats and new taxa of Cerasommatidiidae in the future.	en	Arriaga-Varela, Emmanuel, Tomaszewska, Wioletta, Szawaryn, Karol, Robertson, James, Seidel, Matthias, Ślipiński, Adam, Fikáček, Martin (2023): The resurrection of Cerasommatidiidae, an enigmatic group of coccinelloid beetles (Coleoptera: Coccinelloidea) based on molecular and morphological evidence.
