Literature. Lycoriella (Hemineurina) dearmata Mohrig & Krivosheina—Mohrig et al. (1987) View in CoL : 94, fig. 4 a–d; Menzel et al. (1990): 335; Menzel & Mohrig (1991): 40; Menzel & Mohrig (2000): 382, 385; Komarov (2009): 100, 103.

Discussion. Lycoriella (Hemineurina) dearmata Mohrig & Krivosheina, 1987 is known only from a few specimens from Russia, Tuva and Altai Republics and Germany, Schleswig-Holstein ( Heller 2004) and Thuringia, Saxonia (unpublished). The species was placed in the L. vitticollis group by Menzel & Mohrig (2000) but is exceptional in having a narrow gonostylus, medially not impressed, with a group of subapical megasetae and 2–3 medial elongated setae, and in having a peculiar intergonocoxal lobe of the hypopygium with unusually strong setae. Mohrig et al. (1987: 94) and Menzel & Mohrig (2000: 382) showed that the placement of L. dearmata in the L. vitticollis group of Lycoriella (Hemineurina) was somewhat problematic. The sensillar patch of the 1 st palpal segment is distinctly bordered (not deepened and pit-like), the wing vein R 5 are apically both dorsally and ventrally setose, the scutellum has 4 long and strong setae, the fore tibia has weak spinose setae [1–3 setae in the basic vestiture], the legs are long and thick, the fore tibial organ has fine and dense setosity and bow-like borders, and the tarsal claws are untoothed. It is striking that that the setosity of mesonotum and abdomen is, unlike the species of Lycoriella , Hemineurina und Trichocoelina , dark brown and much longer and dense. Furthermore, the species has a slender, not impressed gonostylus (without medial margin), 2 or 3 elongated and nearly straight setae on its apical half (not homologous with the apically curved whiplash seta of Lycoriella s. l.) and a slender apical tooth and 2 to 3 strong and nearly straight subapical megasetae. These characters support the view that L. dearmata is closer to the species of Bradysiopsis than to the here proposed genera Hemineurina and Trichocoelina (compare here with, for example, Bradysiopsis vittigera ( Zetterstedt, 1851) in Menzel & Mohrig (2000: 189 , fig. 159) and Bradysiopsis sordida ( Mohrig, 1999) comb. n. (see below). The two, very closely placed intergonocoxal lobes of L. dearmata are in no case homologous with with the intergonocoxal lobes of Lycoriella s. str., Hemineurina or Trichocoelina , because at the base they are united with the intergonocoxal area by a strongly sclerotized bridge. Based on the above characters, Lycoriella (Hemineurina) dearmata Mohrig & Krivosheina is transferred to Bradysiopsis Tuomikoski.
