![]() Un'ora fa scoperto questo pselafino nel materiale raccolto con trappola a caduta, e pochi giorni fa ricevuto una proposta per scattare una fotografia di qualcosa di simile... qui è il mio primo pselafino. Mi dispiace che la preparazione non è perfetta come quela di Jan... ma e primo. ![]() Un nome? Raccolto con trapola a caduta, 9.VII-15.VII.2010, vicino a Bunta (Transylvania) 46.277588/23.124758, dimensione - meno di 2 mm. |

At 5x the distance is around 2,5 cm ... at 4x ~~~3-3.5 cm Loriscola ha scritto: Bravo Cosmin, splendida foto.....soprattutto per il soggetto ![]() Ovviamente non posso essere di molto aiuto, ma direi che appartenga al genere Bryaxis.... ![]() Grazie Loris, in attesa di Jan ![]() |

Hi guys. I do not know all the romanian Bryaxis species but I know most of them. According to antennae I´d say it´s B. glabricollis. BUT as far as I know there was a problem concerning B. glabricollis and B. ullrichi. Can´t say now if it a problem about syn. or if there are two species with different distribution. Some time ago, B. ullrichi was mentioned for the Czech republic but nowadays only B. glabricollis is mentioned for central Europe. |

Honza, I studied this problem a little bit and this is a result of it including my experiences: - B. glabricollis is quite common species living in central Europe, mostly in deciduous forests, typically in the surrounding of Prague (Bohemian Karst, Vrané nad Vltavou...). Males are well characterised by penis and antennae. - B. clavicornis is a rare species which I´ve only found around Hradec Králové (fluvial deposits of the Orlice). Males: penis and antennae. - B. ullrichi: penis and it doesn´t live in central Europe. It means: 1) I determine specimens from the Czech republic as B. glabricollis and not as B. ullrichi which is accidentally sometimes still mentioned in CZ check-list. 2) The depicted beetle could be B. ullrichi (penis needed!). 3) B. clavicornis is a different beetle than B. glabricollis (at first sight - the only possibility is that the both species were called "glabricollis" and this name remained valid to only one of them). But... we never know if some clever taxonomist changes everything ![]() |

la letteratura V. Assing & M. Schülke (2006) published the next addenda to the staphylinids of Central Europe with the synonym of the next species: Euplectus mutator Fauvel, 1895 = fauveli Guillebeau, 1888 Bryaxis ullrichii (Motschulsky, 1851) = glabricollis (Schmidt-Goebel, 1838) Rybaxis longicornis (Leach, 1817) =laminata (Motschulsky, 1836 Löbl,Smetana, 2004

Well, Honza. I know this literature and respect the author´s opinion. But I have my own ![]() By the way, in this work, there are some mistakes and I´d be interested on which information are Mr. Löbl´s data based on. In general I think there is nothing more to say about Bryaxis glabricollis. I´ll show you my specimens and maybe can turn you ![]() |
