New and known extinct species ofRhyzobiusStephens, 1829 shed light on the phylogeny and biogeography of the genus and the tribe Coccidulini (Coleoptera: Coccinellidae)

Description of Euchre gen. nov., a new Coccidulini genus (Coleoptera: Coccinellidae) from the Euchre Valley in Australia

“…Euchre is probably most related to the genus Rhyzobius Stephens; however, Rhyzobius itself is a heterogenous assemblage of several lineages (Szawaryn & Tomaszewska 2021; Tomaszewska 2010). Nonetheless, none of the Rhyzobius lineages possess a chin piece, compact and relatively broad antennal club and broad and long ventral antennal grooves that extend to prosternum.…”

First Record of the Genus Cartorhynchites Voss, 1958 (Coleoptera: Rhynchitidae) from Eocene Baltic Amber with a List of Fossil Tooth-Nosed Snout Weevils

“…Studies of the fossil Coleoptera fauna in Baltic amber have been particularly intensive in the last decade. An especially large amount of material has been processed, or sufficient study progress has been made for such beetle groups as, for example, the predatory Cantharidae [ 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 ] and Coccinellidae [ 114 , 115 , 116 , 117 , 118 ], as well as the herbivorous Cerambycidae [ 119 , 120 , 121 , 122 , 123 , 124 , 125 , 126 , 127 , 128 , 129 ].

New descriptions of species and genera have significantly added to the picture of the fossil beetle assemblage in the Fennosarmatian landmass during the Late Eocene and made adjustments to the conclusions about the paleoecosystems of amber forests.…”

Revision of the genus Coccidula Kugelann (Coleoptera, Coccinellidae)

“…The largest and most widely distributed is the genus Rhyzobius Stephens, 1831 with more than 100 recognized species ( Tomaszewska 2010 ; Czerwiński et al 2020 ) and numerous undescribed species mainly from New Guinea. Interestingly it is also the only genus of Coccidulini with known fossil representatives from the Eocene period discovered in Oise ( Kirejtshuk and Nel 2012 ) and Baltic ambers ( Szawaryn and Tomaszewska 2020 ).…”
