Abstract
We recognized Linnaemya microchaetopsis Shima, L. picta (Meigen) and L. zachvatkini Zimin in Korean Linnaemya subgenus Ophina Robineau-Desvoidy and the latter two are reported for the first time in Korea. The subgenus Ophina shares the following morphological characteristics (sensu Shima): 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 the tergite 7; 4) circus parallelsided in caudal view; 5) epiphallus present; and 6) pteropleural seta long, reaching posterior margin of lower calypter. We provide a key to the included Korean species, as well as descriptions and illustrations with their diagnostic characters indicated.

INTRODUCTION
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.
MATERIALS AND METHODS
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 R 4+5 ratio (distance along vein R 4+5 between cross vein R-M and vein R 4+5 apex/distance between cross vein R-M and basal node of vein R 4+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).

Diagnosis. This species can be readily distinguished from other Linnaemya species by the following combination of characteristics; 1) 2 lateral scutellar setae; 2) single strong outer vertical seta in male; 3) frontal vitta wider than parafacial, parallel sided; and 4) claw and pulvillus of male slightly shorter than 5th tarsomere.

We are grateful to Shima H for making the holotype ofL. microchaetopsisavailable to us upon Han HY’s visitingKyushu University in 2002, and also for providing the voucher specimens of manyLinnaemyaspecies (Shima, 1986), on which identifications of Korean species were largely based. We also thank Woodley NE for the loan of someLinnaemyaspecimens used in this study. We appreciate the assistance of Ro KE, Choi DS, Byun HW, Lee HS, Suk SW, Jung JM and Lee YB for the collection of KoreanLinnaemyaspecimens. This study was supported by “The Survey of Korean Indigenous Species” supported by National Institute of Biological Resources (NIBR) of the Ministry of Environment of Korea.
