A. KOMAREK: Taxonomic revision of Agraphydrus RÉGIMBART, 1903 IV. Africa, Western Asia, and redescription of the genus (Coleoptera: Hydrophilidae: Acidocerinae), p. 127-200
The species of Agraphydrus RÉGIMBART, 1903 from Africa and Western Asia are revised, and the genus Agraphydrus is redescribed based on the hitherto known species. Agraphydrus albescens (RÉGIMBART, 1903), A. minutissimus (KUWERT, 1890), A. praecipuus (ORCHYMONT, 1937), A. punctatellus RÉGIMBART, 1903, and A. villiersi (BALFOUR-BROWNE, 1958) are redescribed. Twenty-five new species are described: A. acutus sp.n., A. aethiopicus sp.n., A. andringitra sp.n., A. angustatus sp.n., A. atripalpis sp.n., A. bicoloratus sp.n., A. bilardoi sp.n., A. biltoni sp.n., A. camerunensis sp.n., A. congolensis sp.n., A. flavescens sp.n., A. flavipes sp.n., A. fontis sp.n., A. gereckei sp.n., A. goldschmidti sp.n., A. madagascarensis sp.n., A. malkini sp.n., A. matoposensis sp.n., A. pauper sp.n., A. rhodesiensis sp.n., A. rivalis sp.n., A. scutifer sp.n., A. tumidus sp.n., A. usambaraensis sp.n., A. vadoni sp.n. A lectotype is designated for A. albescens. The genus Agraphydrus is recorded from Angola, Botswana, D.R. Congo, Djibouti, Eswatini (formerly Swaziland), Ethiopia, Ghana, Iran, and Nigeria for the first time. First country records: A. albescens (Botswana, Cameroon, D.R. Congo, Kenya, Republic of South Africa), A. minutissimus (Djibouti, Eritrea, Iran), A. punctatellus (Eswatini), A. villiersi (Nigeria). A total of 31 species is now known from the Afrotropical Region (sensu HANSEN 1999b). One of these species, Agraphydrus minutissimus, occurs also in the Western Palearctic Region (northern part of Saudi Arabia and southern Iran), where it is the only known Agraphydrus species. The habitats of A. camerunensis, A. matoposensis, and A. rhodesiensis are unknown, A. vadoni is probably terrestrial, all other species were collected in various aquatic habitats, including several hygropetric ones. Four species were collected at light. Habitus, male genitalia and femora of all species are illustrated, distribution maps are presented. A key to the species of the Afrotropical Region and photographs of sampling localities are added.
A. KOMAREK & H. FREITAG: Taxonomic revision of Agraphydrus RÉGIMBART, 1903 V. Philippine species and their first DNA barcodes (Coleoptera: Hydrophilidae: Acidocerinae), p. 201-242
The genus Agraphydrus RÉGIMBART, 1903 (Coleoptera: Hydrophilidae) of the Republic of the Philippines is taxonomically reviewed aided by COI mtDNA barcodes. Nine new species are described, all currently regarded as endemic to the Philippines: A. abrasus sp.n., A. ampullatus sp.n., A. batak sp.n., A. brevilobatus sp.n., A. occultus sp.n., A. palawanensis sp.n., A. pelingeni sp.n., A. tenuipalpis sp.n., and A. zetteli sp.n. Agraphydrus coomani (ORCHYMONT, 1927), widespread in the Oriental and Australasian regions, is recorded from the Philippines for the first time. COI sequences and thorough morphological examination suggest that this and further species represent a group of closely related, partly cryptic species under current radiation. At least three of them are clearly distinguishable and summarized together with 16 other Oriental Agraphydrus species (A. coomani species group). Habitus, male genitalia and other morphological details are illustrated, distribution maps and a key to the species are presented. Their macro- and microhabitats are briefly discussed. All species are aquatic, although they were also caught at light and in emergence traps.

H. KIPPENBERG & Y. MIKHAILOV: Contribution to the knowledge of Entomoscelis adonidis (PALLAS, 1771) and allied species (Coleoptera: Chrysomelidae: Chrysomelinae), p. 257-290
A review of Entomoscelis adonidis (PALLAS, 1771) (Coleoptera: Chrysomelidae: Chrysomelinae) and its close relatives, here designated as the E. adonidis species group, is presented. The authors support the traditional usage of the name E. adonidis, although it can be supposed that PALLAS (1771) in fact described the species treated herein as E. dorsalis (FABRICIUS, 1777). A new subspecies of E. adonidis, E. a. caucasica KIPPENBERG ssp.n. (Caucasus), is described, and E. a. goliath (ABEILLE DE PERRIN, 1897) from southern Turkey is regarded as a distinct subspecies. Entomoscelis dorsalis is reinstated as a distinct species, and five subspecies with strikingly disjunct distribution areas are established: E. dorsalis dorsalis (eastern Central Europe), E. d. bashkiriae KIPPENBERG ssp.n. (Russia: Bashkortostan), E. d. hammarstroemi JACOBSON, 1901 (Russia: southern Siberia), E. d. iranica KIPPENBERG ssp.n. (Iran) and E. d. turkestana MIKHAILOV ssp.n. (Kazakhstan). Entomoscelis berytensis (REICHE & SAULCY, 1858) is confirmed as a species propria. The following new synonymies are proposed: Entomoscelis americana BROWN, 1942 (= E. adonidis), E. occidentalis occidentalis ESCALERA, 1914, and E. o. thalmanni KOCHER, 1969 (= E. cornea ABEILLE DE PERRIN, 1897), E. suturalis WEISE, 1882 (= E. sacra (LINNAEUS, 1758)). A neotype is designated for Chrysomela sacra LINNAEUS, 1758. Lectotypes are designated for Chrysomela dorsalis FABRICIUS, 1777, C. trilineata FABRICIUS, 1777, Entomoscelis dorsalis hammarstroemi, E. erythrocnema JACOBSON, 1893, and E. suturalis WEISE, 1882. Due to primary homonymy a new replacement name, C. rumex KIPPENBERG nom.n., is proposed for Chrysomela rumicis FABRICIUS, 1787 (nec C. rumicis SCHRANK, 1785). The name Chrysomela melanostoma GMELIN, 1790 is regarded as a nomen dubium.
