Robineau-Desvoidy (1830) erected the genus Linnaemya based on the type-species, L. silvestris Robineau-Desvoidy. World fauna of this genus currently includes 149 valid species, with 51 Palaearctic (Herting, 1984), 42 Oriental (Shima, 1986), seven Nearctic (O’Hara and Wood, 2004), five Australian (Cantrell and Crosskey, 1989), and 64 Afrotropical species (Crosskey, 1980). Among these species, 20 species are known to occur in more than one region.

The genus Linnaemya is currently divided into three subgenera based on their male genitalic structures (Herting, 1961; Shima, 1986): Homoeonychia Brauer et Bergenstamm, Ophina Robineau-Desvoidy, and Linnaemya Robineau- Desvoidy. As a result of an ongoing study of Korean Linnaemya, we here report three nominal species of the subgenus Ophina [=haemorrhoidalis group of the subgenus Bonellimyia by Herting (1961)]. This subgenus shares the following morphological characteristics (Shima, 1986): 1) the male tergite 6 is fused mid-dorsally with sternite 7+8; 2) the female tergite 6 and tergite 7 are almost always divided longitudinally into two hemitergites; 3) the female tergite 6 is always longer than tergite 7; 4) circus parallel-sided in caudal view; 5) epiphallus present; and 6) pteropleural seta long, reaching posterior margin of lower calypter. For the three Korean species, we provide a key, descriptions and illustrations with their diagnostic characters indicated.

The terminology and morphological interpretations used in this paper follow McAlpine (1981) and Wood (1987), but those of male terminalia follow Shima (1986). In addition, we used the following ten ratios (modified from Han and Norrbom, 2005): vertex-head ratio (vertex width/head width); eye ratio (shortest eye diameter/longest eye diameter); fronshead ratio (narrowest width of frons in dorsal view/width of head); gena-eye ratio (genal height/longest eye diameter)- genal height is the distance between the ventral eye margin and the ventral genal margin anterior to the genal seta; parafacial- flagellomere1 ratio (parafacial middle width/flagellomere1 middle width); flagellomere1-pedicel ratio (length of flagellomere 1/length of pedicel); arista-antenna ratio (arista length/antennal length); vein R₄₊₅ ratio (distance along vein R₄₊₅ between cross vein R-M and vein R₄₊₅ apex/distance between cross vein R-M and basal node of vein R₄₊₅); vein M ratio (distance along vein M between cross veins R-M and DM-Cu/distance between cross veins R-M and BMCu); subcosta-costa ratio (length of pterostigma/length of costal cell, both measured along vein C); wing-thorax ratio (wing length/thorax length).

All the Korean specimens examined in this study are deposited in the Division of Biological Science and Technology, Yonsei University, Wonju-si, Gangwon-do, Korea (YSUW).
