Orobainosoma (Histrosoma) vidinense Strasser, 1973a

Haasea guidononveilleri Makarov, 2008 syn. nov.

Diagnosis. Differs from the other congeners by the presence of a strongly developed, knife-like mesal process, parallel and closely fitting to angiocoxite with basal tooth as well as by the presence of rudimentary anterior and posterior lateral processes.

Comments. Strasser (1973a) established the new subgenus Histrosoma Strasser for his H. vidinensis and characterized it by the absence of “Pugio” and “Epithema”. Later, in his description of H. guidononveilleri, Makarov (2008) stated that it is closely related to H. vidinensis and gave some differences between the two species. Also, he ( Makarov 2008) disagreed with Strasser (1973) about the absence of “Epithema” in vidinensis , confirming the presence of this structure in both taxa as a reduced process and disagreed with the validity of Histrosoma . Makarov (2008) compared his guidononveilleri with vidinensis , stating, among others, the presence of both rudimentary “Pugio” and “Cornicle” in guidononveilleri , structures considered absent by Strasser (1973a). After examination of both types, as well as a new material from Serbia, we noticed that posterior lamella (pl) (“Epithema”) is present in both taxa. Mesal process (mp) (“Keratit”) is strongly developed, parallel and closely fitting to angiocoxite, knife-like, with basal posterior tooth. The size of the basal tooth on mp is variable, from short, triangular to somewhat longer, thorn-like. Also, in type specimens of guidononveilleri , mesal process on the right gonopod is without basal tooth. Both species are characterized by the presence of a reduced, small and triangular anterior lateral process (alp) (“Pugio”) with additional mesal sharp projection. Also, both are characterized by the presence of the posterior lateral process (plp) (“Cornicle”), variable from short triangular to somewhat longer, acuminate. It is obvious that Strasser (1973a) overlooked some structures in his vidinensis . On the other hand, Makarov (2008) made drawings from the left gonopod, which was somewhat flattened during the preparation of microscopic slides ( Fig. 26C ) whereas right anterior gonopod remained “normal” and is exactly matching vidinensis .

Considering the absence of consistent differences between the two species and that both taxa inhabit the Carpatho-Balkan caves, near the Serbo-Bulgarian border, we consider H. guidononveilleri as a junior subjective synonym of H. vidinensis .

In the vial and on the microslide of lectotype male of Haasea vidinensis, Strasser clearly indicated on the label “ holotypus ”, as well as paratypes for the rest, but he did not designate a holotype and paratypes in the original description of the species (Strasser 1973). Later, Stoev & Beron (2001: 96–97) repeated what is on the Strasser’s label. However, according to the ICZN 72.4.7: “The mere citation of “Type” or equivalent expression, in a published work other than that in which the nominal species-group taxon is established, or in an unpublished catalogue of a museum, or on a label, is not necessarily evidence that a specimen is or is fixed as any of the kinds of types referred to in this Chapter”. The designation of holotype and paratypes is only valid if it appears in the original description of the species. Since this is not a case with Haasea vidinensis , all the type specimens of this species in NMNHS are considered as syntypes and we here designate a lectotype to fix the species taxonomy.

In his original description, Strasser (1973) stated he examined five males, five females and two juveniles. All specimens of the type series were found in NMNHS and MHNG, with note that one male in NMNHS is without gonopods and leg-pairs 10 and 11, these structures were found on a microslide in MHNG.
