Diagnosis
The new species Trouessartia kharkhanensis Constantinescu et al. sp. nov. is most similar to T. rubecula Jablonska, 1968 described from Erithacus rubecula (Linnaeus) ( Passeriformes , Muscicapidae ) in Poland ( Jablonska 1968), in having, in both sexes, the prodorsal shield with antero-lateral extensions short and rounded, the hysteronotal shields with lateral margins deeply incised at the level of trochanters III, setae d1 present, setae c3 and sRIII lanceolate, and dorsal hysterosomal apertures (DHA) absent. Both sexes of T. kharkhanensis differ from T. rubecula by the following features: setae si and c2 are lanceolate, setae c3 and sR III have acute apex (vs setae si and c2 are needlelike, and setae c3 and sR III have bidentate apex in T. rubecula ). In males of T. kharkhanensis , the adanal apodemes have a hook-like retroverted apophysis, and the inner margins of terminal lamellae have a shallow concavity at the level of setae h3. In males of T. rubecula , the adanal apodemes have a pair of straight apophyses, and the inner margins of terminal lamellae are slightly convex. In females of the new species, setae h1 are spiculiform and their bases are surrounded by small ovoid areas of unsclerotised tegument, and the area bearing sparse ovate lacunae does not extend to the level of setae e1. In females of T. rubecula , setae h1 are lanceolate and their bases are surrounded by the area of unsclerotised tegument, and the area with numerous ovate lacunae exceeds the level of setae e1.

Diagnosis
Proterothrix cyornissimilis Constantinescu et al. sp. nov. belongs to the wol ffi species group, by having almost closed coxal fields III in males and parallel-sided terminal cleft in females. Among all species of the genus, P. cyornissimilis is closely related to P. cyornis Mironov and Tolstenkov, 2013 from Cyornis tickelliae Blyth ( Passeriformes : Muscicapidae ) by having pseudorutelar lobes with acute lateral extensions and a similar shape of dorsal shields in both sexes. Proterothrix cyornissimilis differs from that species by the following features: in both sexes, the prodorsal shield is without ornamentation; in males, the aedeagus extends beyond the level of the anal suckers, a pair of small ovoid shields is located at the tips of the genital arch, the supranal concavity is triangular, setae h3 are situated slightly anterior to setae h2, and the the hysteronotal shield bears only a few small circular lacunae in anterior half; in females, the anterior hysteronotal shield bears a few small circular lacunae, the lobar region is without ornamentation, and the supranal concavity is ovoid. In both sexes of P. cyornis , the prodorsal shield is covered with numerous circular and ovate lacunae; in males, the aedeagus extends to the level of the anal suckers, small sclerites near the tips of genital arch are absent, the supranal concavity is shaped like an inverted teardrop, setae h2 are situated slightly anterior to level of setae h3, and the hysteronotal shield bears circular lacunae on the entire surface; in females, the entire surface of the anterior hysteronotal shield and anterior part of lobar shield bear numerous circular lacunae, and the supranal concavity is circular.
