Limonia crane flies (Diptera: Limoniidae) of Korea

Abstract

The Korean species of Limonia Meigen, 1803 crane flies (Diptera: Limoniidae) are taxonomically revised. Species L. annulata Lackschewitz, 1940 (Lackschewitz, Pagast, 1940), L. bidens Savchenko, 1979, L. episema Alexander, 1924, L. fusciceps fusciceps Alexander, 1924, L. juvenca Alexander, 1935, L. messaurea messaurea Mendl, 1971, L. nemoralis Savchenko, 1983 are new records for the Korean peninsula and L. pia n. sp. is described. Synonymy of L. venerabilis Alexander, 1938 with L. macrostigma (Schummel, 1829) is confirmed. L. tanakai (Alexander, 1921) is not confirmed for the Korean Peninsula. An identification key, redescriptions and illustrations of all species and both sexes of adults, if they were found in Korea, are presented. Descriptions, illustrations and habitat characteristics are given for the previously unknown larva and pupa of L. parvipennis Alexander, 1940. Distinguishing morphological characters of the last instar larvae of Korean Limonia are discussed. Keys to the known Korean Limonia larvae and pupae are compiled.

Two new species of Limonia Meigen, 1803 from Northwest China (Diptera, Limoniidae)

“…Remarks. Limonia is characterized in the family by the following features: body color from yellow to gray, brown or black; medium-sized (body length 5.3-12.1 mm, wing length 5.4-13.2 mm); first thoracic segment elongate; episternum setose; tarsal claw with three to five teeth; wing wide with well-developed anal angle, pattern ranging from completely transparent or patternless to smoky or with dotted markings; Sc 1 apically reaching from base of Rs to branching point of Rs; Sc 2 close to apex of Sc 1 ; terminal section of R 1 continuing direction of R 1 and longer than R 2 (often at least two times longer than R 2 ); discal cell closed; basal deflection of CuA 1 at or slightly before branching point of M; male genitalia with wide ninth tergite slightly emarginate at posterior margin; gonocoxite with wide but often low ventromesal lobe; gonostylus single, situated apically, wider at base, narrowed and slightly arched at apex; aedeagus simple, elongate with bifid apex that is turned into the ventral margin; paramere wide at base; cercus of female terminalia slightly turned upwards (Savchenko 1985;Reusch and Oosterbroek 1997;Stary and Salmela 2004;Kolcsár et al 2017;Podenas and Podeniene 2017;Starý 2018).…”

“…It can be separated from the latter by the following features: body yellow; occiput yellow with Y-shaped marking; gonostylus with obtuse apex; paramere with obtuse apex; aedeagus with strong mid-ventral protrusion. In L. macrostigma, the body is brown; the occiput is black brown; the prescutum has two lateral stripes; the gonostylus has a slender apex; the paramere has a slender and pointed apex; and the aedeagus has no mid-dorsal protrusion (Podenas and Podeniene 2017). Diagnosis.…”

Additions and Corrections to the Fauna of Crane Flies (Diptera: Tipuloidea) of Tver’ Region

“…Широко распространенный, имеющий транспалеарктический ареал вид (Oosterbroek, 2019). Личинки развиваются в гнилой древесине и прелом лиственном опаде (Савченко, 1985;Podenas, Podeniene, 2017). Имаго встречаются в различных достаточно увлажненных биотопах, преимущественно возле водоемов, во влажных лиственных лесах, на опушках леса и мокрых заболоченных лугах (Савченко, 1985).…”
