Genus: Filchnerella Karny, 1908

Karny, 1908: 36. Type species: Filchnerella pamphagoides Karny, 1908

Pseudotmethis Bey-Bienko, 1948 (Type species: Pseudotmethis alashanicus Bey-Bienko, 1948) syn. nov. Paratmethis Zheng & He, 1996 (Type species: Paratmethis flavitibialis Zheng & He, 1996) syn. nov.

Remaks. The genus Pseudotmethis established by Bey-Bienko (1948: 6) was mainly distinguished from Filchnerella Karny by the presence of strongly developed, plate-like facial carinae, which are slightly developed and weaker in Filchnerella (weaker also in Mongolotmethis Bey-Bienko). The small differences of fastigium of vertex and tegmina are variable. The structures of the male phallic complexes of the species studied of both genera undoubtedly belong to a single genus. Only the more raised facial carina does not make it an independent genus (Figs. 243–245).

On the other hand Zheng & He (1996: 294, 296) established the genus Paratmethis, which was poorly described and distinguished from Filchnerella by the presence of concavity below the median ocellus; from Eotmethis Bey-Bienko by the rounded vertex towards fastigium. But it is possible to see the same structure of frontal ridge in Filchnerella . For instance the frontal ridge of Paratmethis flavitibialis Zheng & He, 1996 is almost the same with the types of Filchnerella kukunoris Bey-Bienko, 1948 (Fig. 243).

The differences given by Bey-Bienko (1948) and Zheng & He (1996) are not enough to establish a new genus, being no distinct characters in the male phallic complex along with the external morphology. Therefore the genera Pseudotmethis and Paratmethis are proposed as junior synonyms of Filchnerella .

The listed species below are given in new combinations because of the synonymies of their previous genera:

Filchnerella rufifemoralis (Zheng & He, 1996) comb. nov.

Filchnerella gansuensis (Xi & Zheng, 1984) comb. nov.

Filchnerella rubimarginis (Li, 1986) comb. nov.

Filchnerella flavitibialis (Zheng & He, 1996) comb. nov.

Filchnerella brachypterus (Li, 1986) comb. nov.

According to the ICZN (Article 34.2) the species name of this taxon is combined.
