New and little known species of Alleculini (Coleoptera: Tenebrionidae: Alleculinae): extinсt from Eocene Baltic Amber and extant from Lebanon

Abstract

Three new species of comb-clawed beetles of the tribe Alleculini (Tenebrionidae: Alleculinae) are decribed. Gonodera baygushevae Nabozhenko et I. Chigray, sp. n. (Eocene Baltic amber) is similar to extant Gonodera rufoaenea Reitter, 1900 by very finely and sparsely punctated elytral intertriae, but differs in the small size of body (6.6 mm, while other species of Gonodera Mulsant, 1856 have a minimal length of 8 mm), elongate punctation of head, subequal width of elytral and pronotal bases and six teeth on both clavae (other Gonodera have seven teeth). Gonodera kasatkini Nabozhenko, sp. n. (extant, Lebanon) belongs to the species-group with subequal antennomeres 3 and 4 of male and differs from all other species of this group in the absence of basal impression on pronotal disc and strongly depressed 5th elytral interstria at base. Mycetochara (s. str.) abdurakhmanovi Nabozhenko, sp. n. (extant, Lebanon) differs from all Western Palaearctic Mycetochara s. str. in the combination of red protorax with black elytra, large longitudinal oval impression in the middle of anterior half of pronotum and 10 long lanceolate spines on apical lobe of aedeagus. New distributional data for Isomira (s. str.) antennalis Reitter, 1884 (the first record for Lebanon), Mycetochara (Ernocharis) ruficollis Baudi di Selve, 1877 and Hymenalia ehdenica Novák, 2017 are given
