INTRODUCTION
The genus Campsicnemus Haliday in Walker et al., 1851 belongs to the subfamily Sympycninae and numbers about 290 species with an extremely high diversity of endemic species in the Hawaiian Islands and French Polynesia [Evenhuis, 2009; 2012]. Grichanov [2009] listed and keyed recently 36 known Palearctic species. Later one more Palearctic species of Campsicnemus was described from Astrakhan Province of Russia [Grichanov, 2011]. Here I describe a new species C. zlobini sp. nov. from the Primorskii Krai Province of Russia. This paper presents also new records for species of the genus Campsicnemus.
Morphological terminology mainly follows Cum-ming & Wood [2009]. Body length is measured from the base of antennae to the posterior tip of epandrium. Wing length is measured from the base to the wing apex. The relative lengths of tarsomeres should be regarded as representative ratios and not measurements. Male genitalia were not dissected and figured as they have low taxonomic value in the genus Campsicnemus [Evenhuis, 2009, 2012]. The holotype of new species and other materials examined are housed at Zoological Institute of the Russian Academy of Sciences, St. Petersburg (ZIN). For the information on global distribution for each species listed see Grichanov [2009].

Etymology. The species is named for the late Russian dipterist Vladimir Zlobin (ZIN) who collected the holotype.
Diagnosis. The new species is close to C. versicolo-rus Negrobov et Zlobin, 1978 described from the Pri-morskii Krai of Russia (Yakovlevka, Novodevitsa, Komarovo-Zapovednoe), differing in dark face, short postpedicel, mainly black legs, in armament of mid leg etc. Both species are related to the C. armatus group of species. Below are the modified couplets in the key to Palearctic species of the genus published by Grichanov [2009]:
33. Mid tibia without a comb-like ventral row of blunt-ended bristles, with rows of simple hairs and setae; mid basitarsus as long as next segment .... 34
- Mid tibia with a comb-like ventral row of blunt-
ended bristles; mid basitarsus distinctly longer than next segment......35
34. Face dark; postpedicel hardly longer than high at base; legs mainly black; mid tibia without row of long bristles, with full row of erect posteroven-tral setae, nearly as long as diameter of tibia; 2.3 C. zlobini Grichanov, sp. nov.
- Face silvery white; postpedicel 2 times longer than high at base; legs almost completely pale yellow; mid tibia with row of 7-8 bristles in distal 2/3, two times longer than diameter of tibia; 1.3-1.5 ................. C. versicolorus Negrobov et Zlobin
35. Mid femur, at least in basal half, with a postero-ventral row of sparse bristles, about as long as diameter of femur; mid tibia with a comb-like row of blunt-ended bristles in basal half only; 1.7-2.4 C. vtorovi Negrobov et Zlobin
- Mid femur with very short ventral hairs, or with a
row of bristles, at most 2/3 as long as greatest diameter of femur.................................36
36. Mid femur with very short ventral hairs; mid tibia
with a comb-like row of blunt-ended bristles in basal half only; 1.5.......C. pumilio (Zetterstedt)
- Mid femur, ventrally along almost whole length, with a row of bristles, some of which are more than 2/3 as long as greatest diameter of femur; mid tibia, ventrally along almost whole length, with a comb-like row of blunt-ended bristles; 1.25-2.0 ... ..........................C. armatus (Zetterstedt)
