Allotrichoma filiforme Becker, 1896: 123 ; type-locality:„Sarepta” [ Russia, Europe]; lectotype ♂, des. by Papp [1979] ( Germany, Berlin, Museum für Naturkunde der Humboldt-Universität [ Papp, 1979]).

= Allotrichoma dahli Beschovski, 1966: 937–939 ; type-locality: „Kap Galata an einer Waldquelle” [ Bulgaria]; holotype ♂ ( Bulgaria, Sofia, National Museum of Natural History [ Beschovski, 1966]).

TYPE MATERIAL EXAMINED: Lectotype (♂) of Allotrichoma filiforme Becker, 1896 : (1) “Sarepta / Christoph”; (2) “4/4”; (3) “lateralis ?”; (4) “Coll. / H. Loew ”; (5) “14391”; (6) “ Allotrichoma / filiformis [sic!] / Becker.”; (7) “Type”; (8) “ Lectotypus ”; (9) “Zool. Mus. / Berlin ”. Lectotype is deposited in ZMHB. The type specimen was double pinned and this part of the type is lost. Abdomen had been previously removed, macerated and dissected but was dried out. I placed the abdomen in a microvial filled with glycerine.

TAXONOMIC REMARK: Allotrichoma filiforme was synonymised by Papp [1979], this synonymy can be confirmed herewith. Stuke [2013] showed that there are two similar species occurring sympatrically in southwest Germany. One species was identified as A. dahli and the other incorrectly as A. filiforme . In fact, all records of A. filiforme sensu Stuke belong to A. trispinum .

DISTRIBUTION: Because the distinction of A. filiforme and A. trispinum had not been clearly pointed out, older faunistic records of A. filiforme are difficult to judge. The type material of A. filiforme and A. dahli originated from “Kap Galata” ( Bulgaria) and “Sarepta” (Volgograd, Russia, Volgograd Oblast). Papp [1974], who compared his specimens with material identified by Beschovski as A. dahli , mentioned that the species is the most common Allotrichoma species in Hungary. Stuke [2014] found A. filiforme (as A. dahli ) to be quite common in Greece and later there have been more northern finds from Germany [Stuke, 2013; Stuke, Bährmann, 2013; Stuke et al., 2020; all as A. dahli ]. Howev- er, in Central Europe A. filiforme is at least in some areas less common than A. trispinum . The data presented here show that A. filiforme is widely distributed in Europe with only one record outside Europe, from Kyrghystan ( Fig. 26 ). Probably several or most records published as A. filiforme will turn out to belong to this species.
