Abstract. The article provides some corrections and additions to the list of Elaterids of Mongolia. Oedostethus sincerus Gurjeva, 1975 and Oedostethus petrenkoi Dolin, 1992 are new for Mongolia. The announcement of Fleutiauxellus maritimus Curtis, 1840 for Mongolia has been revised. An identification key to the species of the genus Oedostethus LeConte in Mongolia is presented.

Introduction

     In a recent publication, a list of Mongolian Elaterids has been presented (Jarzabek-Müller & Neméth, 2014). This list is now revised and complemented. The revision shows that the species Fleutiauxellus maritimus Curtis, recorded from the province Zavakhan in Mongolia has been mistaken. The species is Oedostethus latissimus Tsherepanov. The confusion is based on identical traits for both genera Fleutiauxellus Méquignon and Oedostethus LeConte. It seems obvious that the current Oedostethus genus has to be further divided. Some species probably have to be transferred to Fleutiauxellus, and to other, maybe new genera. Japanese authors (Kishii 1976, 1987, Ohira 1988) described many new genera for Japanese Negastriinae, but outside Japan similar species, still are described as Oedostethus, despite clear distinction in their aedeagus. Beyond Oedostethus latissimus Tsherepanov also Oedostethus mystax Gurjeva from Mongolia and Sibiria or Oedostethus submontanus Dolin & Bessolitzina recorded from Sibiria show characteristics typical for Fleutiauxellus. Thus further research based on phylogenetic is required to illuminate the relationship of this complex in elaterids.
     Moreover, the revision revealed a specimen determined by Gurjeva as Oedostethus latissimus (Jarzabek-Müller & Neméth, 2014), as a female of Oedostethus petrenkoi Dolin.
     To facilitate the determination of the species of the genera Oedostethus from Mongolia under consideration of Fleutiauxellus maritimus a key using information from Russian, English and German literature has been developed. (Dolin 1992, Gurjeva 1968, 1969, 1975a, b, Reitter 1895, 1905, Tsherepanov 1957).  
 

Complementary notes on the list of Elateridae of Mongolia

Aeolosomus rossii Germar, 1844
subfamily Agrypninae Candèze, 1857

E. L. Gurjeva reported this species for Mongolia already in 1968 (Gurjeva 1968, 1969).

Agriotes unicolor Koenig, 1889
subfamily Elaterinae Candéze, 1863

On the basis of type material Agriotes soederbomi Fleutiaux, 1936 was synonymized with Agriotes unicolor Koenig, 1889 by G. Platia (2007).

Ampedus mannerheimi Suzuki, 2013
subfamily Elaterinae Candéze, 1863

W. Suzuki renamed Ampedus basalis (Mannerheim, 1852) as Ampedus mannerheimi Suzuki, 2013.

Ampedus tristis Linnaeus, 1758
subfamily Elaterinae Candéze, 1863

1915 G. G. Jacobson mentioned this species for Mongolia (Jacobson 1905-1915). However, this information has been second-guessed.

Fleutiauxellus maritimus Curtis, 1840
(Fig. 5, 16, 34, 53)
subfamily Negastriinae Nakane & Kishii, 1956

This species has to be removed from the checklist of Mongolia.

Oedostethus petrenkoi Dolin, 1992
(Fig. 2, 31, 49)
subfamily Negastriinae Nakane & Kishii, 1956

E. L. Gurjeva determined the specimen in Fig. 31 in 1968 as Oedostethus latissimus Tsherep., but it is a female of Oedostethus petrenkoi Dolin, a species first described in 1992 by Dolin (Dolin 1992). The females of both species are very similar, but the antennae of Oedostethus petrenkoi almost extend to posterior angles of pronotum, while the antennae of Oedostethus latissimus extend two segments past posterior angles of pronotum. The elytra of Oed. petrenkoi are more convex, while the elytra of Oed. latissimus are more flat.
