New species ofElectribius Crowson 1973 (Coleoptera: Artematopodidae) from Baltic amber

Jurassic artematopodid beetles and their implications for the early evolution of Artematopodidae (Coleoptera)

“…Electribius Crowson, 1973. Data from Crowson (1973, Lawrence (1995Lawrence ( , 2005 and Hörnschemeyer (1998) and dissection of holotype of E. crowsoni Lawrence. Eurypogon Motschulsky, 1859.…”

“…With approximately 70 described species in nine genera, Artematopodidae is a small family of beetles forming one of the basal lineages of Elateroidea (Hörnschemeyer, ; Lawrence, , ). The family includes three subfamilies: Electribiinae ( Electribius Crowson, Mexico, Central America, Baltic amber of northern Europe); Allopogoninae ( Allopogonia Cockerell, California); and Artematopodinae ( Artematopus Perty, Central and South America; Brevipogon Lawrence, California; Carcinognathus Kirsch, South America; Ctesibius Champion, Mexico and Central America; Eurypogon Motschulsky, North America, Italy, eastern Russia, China, Japan; Macropogon Motschulsky, North America, Asia; and Proartematopus Crowson, Baltic amber of northern Europe) (Crowson, ; Lawrence, , , ; Young, ).…”

“…To date, fossil artematopodids were confined to the Middle Eocene Baltic amber (Lawrence, ). Two genera are known: Electribius , with four extinct and two Recent species, and the monotypic genus Proartematopus (Crowson, ; Lawrence, ; Hörnschemeyer, ). The inclusion of the Baltic amber species Electrapate martynovi Iablokov‐Khnzorian (Iablokoff‐Khnzorian, ) by Lawrence () is considered erroneous.…”

“…With approximately 70 described species in nine genera, Artematopodidae is a small family of beetles forming one of the basal lineages of Elateroidea (Hörnschemeyer, 1998;Lawrence, 2005, There seems little doubt that species of Eurypogon and Macropogon are closely associated with and probably feed on mosses growing on boulders (Lawrence, 2010); however, Artematopus larvae in Brazil were reared through to the adult stage on cut-up pieces of insects (Costa et al, 1985) The adult artematopodids resemble certain elaterids in superficial appearance (Fig. 1), but are easily separated from the latter by a curious feature -a tongue-like process associated with the apicoventral region of the elytron (Young, 2002;Lawrence, 2005).…”

A new extant species of Electribius Crowson from Honduras (Coleoptera: Elateroidea: Artematopodidae)

“…The Artematopodidae are a small group of phylogenetically early-branching elateroid beetles supposedly related to Omethidae (Kundrata et al 2014). The extant component of the family currently consists of three subfamilies, eight genera and 67 species distributed in the Holarctic, Oriental and Neotropical regions (Hörnschemeyer 1998;Lawrence 2005; Arriaga-Varela & Escobar 2014), with an additional two monotypic fossil genera and six fossil species (Lawrence 2010). The adults are diverse in body form but share numerous presumed synapomorphies, including tarsomeres 3 and 4 with membranous lobes and a tongue-like process on the underside of the apex of the elytra (Crowson 1973).…”
