X-ray microscopy reveals endophallic structures in a new species of the ground beetle genus Trechus Clairville, 1806 from Baltic amber (Coleoptera, Carabidae, Trechini)
The third fossil species of the genus Trechus Clairville, 1806 is described from Baltic amber: Trechus exhibitorius sp. n. Details of external and internal morphology were analysed using X-ray micro-computed tomography (micro-CT) and important diagnostic features of the internal male genital sac (endophallus) are described in detail for the first time in a fossil ground beetle. Based on these d...
متن کاملConfirmation of occurrence of Trechus Clairville, 1806 in the Baltic amber forests, with description of a flightless edaphic species, and remarks on Trechoides Motschulsky, 1856 (Coleoptera: Carabidae: Trechini).
The first reliably identified Trechini beetle species from Baltic amber, Trechus balticus sp. n., is described. This new fossil species is most similar to extant species of the Palaearctic Trechus sensu stricto, as well as to the Nearctic Microtrechus Jeannel, 1927. Since the fossil specimen is a female and some important character states cannot be investigated, its true systematic position wit...
متن کاملA new fossil species of the genus Coptodera Dejean, 1825 (Coleoptera: Carabidae: Lebiinae) from Baltic amber.
In this paper a new species of fossil ground-beetle, Coptodera elektra n. sp. (Coleoptera: Carabidae) preserved in a piece of Baltic amber (Eocene) is described and the paleobiology of the species is studied. This new species represents the first known fossil record for the genus, as well as the first record of its presence in Europe.

This species group ranges from southern China, crossing Indochina and Myanmar to eastern India. To date, the jianfengling species group is composed of ten species, including six new species which are hereinafter described and illustrated: Orthogonius wrasei sp. n. (Myanmar), Ort...
متن کاملFossil carabids from Baltic amber--III--Tarsitachys bilobus Erwin, 1971 an interesting fossil ground beetle from Baltic amber (Coleoptera: Carabidae: Trechinae): Redescription and comments on its taxonomic placement.
Tarsitachys bilobus (Coleoptera, Carabidae) is a fossil species described by Erwin from Baltic amber. Its description was based on only one known specimen, and thus, part of its anatomical structures were unknown as they were poorly preserved in the Holotype. In this paper we complete the description with a second specimen. A new placement among Tachyina and a new status for the genus are propo...
