Reservoir in Yeongdeok-ri , Bukmyeon , Yeongwol-gun , Gangwon-do , Korea , 37°17 ʹ 05.6 ʺ N , 128°26 ʹ 09.9 ʺ E . Collected by Hee-Min Yang on 20 Jun 2019 (NNIBRIV50292) . Description. Hard lorica. Anterior margin of lorica straight. Antero-lateral corner angulate. Dorsal plate narrower than ventral plate anteriorly, wider in middle. Length of dorsal and ventral plate similar. Lorica 62.5 - 65.0 μm in length. Width of dorsal lorica 57.5 - 60.0 μm, ventral lorica 50.0 - 52.5 μm. Prepedal folds long and narrow. Foot plate wide and foot pseudosegment squircle. Foot pseudosegment not protruded from foot plate. Toe single with terminal fissure. Toe length 20.0 μm ( Fig. 2A, B ). Trophi malleate. Upper part of manubria thick, tapering narrow toward the end. The end of manubria curved inwards. Fulcrum short and thin in ventral view ( Fig. 2C ). Distribution. Cosmopolitan. Remarks. Lecane furcata is a cosmopolitan species and the most common lecanid rotifer found in submerged vegetation ( Segers, 1995 ). External characteristics of the lorica of L. furcata are similar to those of the following lecanid rotifers: L. acanthinula (Hauer, 1938) ; L. braziliensis Segers, 1993 ; L. dumonti Segers, 1993 ; L. inconsipicua Segers & Dumont, 1993 ; L. inopinata Harring & Myers, 1926 ; L. rugosa ( Harring, 1914 ) ; and L. undulata Hauer, 1938 ( Segers, 1995 ). Lecane furcata can, however, be distinguished from these species in that it has completely fused toe with a terminal fissure, an absence of antero-lateral spines, and by the ratio of the lorica/toe length.
