Multiple origins of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae): molecular phylogeny, overview of genera and a new genus from Africa Author Damaška, Albert František Author Konstantinov, Alexander Author Fikáček, Martin text Zoological Journal of the Linnean Society 2022 2022-02-07 196 647 676 journal article 10.1093/zoolinnean/zlab112 eb68c3ad-c51a-4828-8a1f-314ed0ba6454 0024-4082 7196247 1C9A93CC-F5BE-427B-95B4-B2B9A1F51B46 KISKEYA KONSTANTINOV & CHAMORRO- LACAYO, 2006 ( FIG. 3 ) Type species: Kiskeya baorucae Konstantinov et al ., 2006 . Synonyms: No generic synonyms. Phylogenetic position: We found Kiskeya deeply nested inside the ‘Disonychine–Monoplatine’ clade, belonging to the Disonycha generic group, where it stands as a sister-lineage to all its remaining members. Diversity and distribution: Five species of Kiskeya are known to date. The genus is endemic to the West Indies. Revisions: New species with keys provided are described in Konstantinov & Konstantinova (2011) and Konstantinov et al . (2020). Morphological characteristics: Body extremely small ( 0.8–1.1 mm ), strongly ovate and extremely convex in lateral view. Head hypognathous. Antennae with only nine antennomeres, short, four apical antennomeres strongly widened, forming a compact and rounded antennal club. Pronotum strongly convex, bearing a pair of basal setiferous pores on lateral margin. Elytra extremely convex, round, nearly lacking punctures. Procoxal cavities closed posteriorly. Metaventral process short, triangular, not covering the mesoventrite in the space between the mesocoxae. Metafemora strongly widened, metatibiae slightly curved. The first abdominal ventrite bears a distinct ridge surrounded by deep punctures, with an anterior process reaching the space between metacoxae. Aedeagus simple and parallel-sided, curved in lateral view. Spermatheca subcylindrical, pump wide and relatively long. Spermathecal duct extremely short. Ecology: Specimens of Kiskeya were collected in cloud forests by sifting or individually from moss cushions. Larvae were also collected in the same moss samples (Konstantinov, unpubl. data). Remarks: The morphology of Kiskeya represents an extreme specialization for edaphic lifestyle, making Kiskeya completely different from all known Neotropical alticine genera. In worldwide fauna, the only similar genus is the Asian genus Clavicornaltica , which is diagnosed from Kiskeya above.
