A new record of genus Synedrus Graham, 1956 with description of male of Synedrus kasparyani Tselikh, 2013 from India

.

The genus Synedrus Graham, 1956 based on the type species Synedrus cavigena Graham, 1956 was described from France.The genus is represented by only three species, viz: Synedrus crassicornis Graham, 1992 (from France); Synedrus kasparyani Tselikh, 2013 (from Russia & South Korea), and Synedrus transiens (Walker, 1835) (from Bulgaria, Czech Republic, Czechoslovakia, Netherlands, Sweden, United Kingdom, and Russia).As such there is no host record for the species of Synedrus Graham, 1956 except Synedrus transiens (Walker, 1835) has been found to be associated with Fagaceae family (Quercus sp.) (Noyes, 2019).In the present study, both male and female specimens of Synedrus kasparyani Tselikh, 2013 were found to be associated with Rutaceae family (Citrus sp.).

Materials and Methods
The specimens were collected during field survey from Jammu & Kashmir in June 2021 with aspirator from Citrus and preserved in 80% alcohol.Specimen were examined under MAGNUS MSZ-Bi binocular microscope at FRI, Dehradun and genus level identification was done with the key of Bouček & Rasplus (1991); species level identification was done with that of Tselikh (2013) and Graham (1969).For the better description of the characters, photographs have been taken under Leica M-205C trinocular stereo zoom microscope fitted with HD camera, and images were analyzed with LAC-16 image analyzing software at systematic laboratory, Forest Entomology Discipline, ICFRE-FRI, Dehradun.
Morphological terminology follows Gibson (1997).Specimen deposition: The specimens were deposited in National Forest Insect Collection (NFIC), Forest Research Institute, Dehradun, India and accession number was obtained.

Synedrus Graham, 1956
Genus Synedrus Graham, 1956 can be identified by the combination of characters: antennal formula 11353, while 11263 in male, 3 rd anelli quadrate in female with micropilosity extending up to base of clava; pronotal collar carinate in both sexes; scutellum convex in profile/ lateral view.Nucha reticulate and long, median carina absent; traces of transverse carina are present; petiole transverse; stigma of FW moderately capitate; PMV longer than MV.
The male specimen of Synedrus kasparyani Tselikh, 2013 has been described here and the notes and illustrations of female specimen has been provided.
Synedrus kasparyani has been described from Russia based on the female type.It is first time recorded from India and its detailed morphological diagnostic note is provided here.
Mesosoma: pronotal collar much narrower than mesoscutum, hind margin of mid lobe of mesoscutum produced, prepectus small, median carina absent, metanotum including dorsellum smooth & shiny; plicae sharply present, traces of transverse carina are present, spiracles oblong are of normal size, a spine or fingernail like structure is present on both the sides of callus, long white hairs present on both sides of callus; FW bare in basal part, basal setal line present, cubital setal line absent, SMV 0.36x as long as FW length, stigma of FW moderately capitate, uncus present, short marginal fringes also present.
Metasoma: T1 longest, its hind margin slightly produced; hind margin of each tergite with at least one row of white setae, hypopygium reaching half of gaster (base of T4); ovipositor, exerted outside last tergite.
Biology: Specimens were collected from Citrus sp.
Color: (Image 2A-I).Head, mesosoma metallic green with diffuse coppery lustre, mandibles yellowish-brown except teeth brownish, eyes dark brown; antennae brownish with scape yellowish and pedicel testaceous; FW hyaline, veins brown.Legs with all coxae concolorous with mesosoma, proximal part of hind femur testaceous, rest of legs yellowish, tips of tarsal segments brown.Gaster bluish blackish or brownish with median part yellowish.
Sculpture: Head and mesosoma strongly and uniformly reticulate except clypeal region smooth with striae radiating from mouth margin, reticulation on malar region finer, axillar edges smooth; frenal area and nuchal reticulation same; metanotum, dorsellum, and callus smooth.
Head: (Image 2B-E).Clypeal margin with broad and short tooth, clypeal region distinctly separated from face with striae radiating from mouth margin.Head in frontal view 1.36x as broad as head height and dorsally 2.22x as broad as long; eyes 2.47x as long as broad; malar space 0.53x as long as eye length; antennal torulivertex 0.61x as long as antennal toruli-clypeus; distance between eyes 0.62x as long as head breadth; POL 1.27x OOL; temple 0.18x as eye length.Genal suture strongly present; Mandibles with four teeth each.Antennae (Images 2D,E) 11263, inserted nearly in the middle of face with scape reaching or slightly above median ocelli, antennal scrobes shallow, all flagellar segments hairy, distinctly longer than broad; pedicel somewhat globular, F1 approximately 2x pedicel, clava longer than two preceding flagellar segments combined (F5+F6).
Biology: Not known.Associated with citrus plant and collected with the help of aspirator.

Discussion
The female specimen of Synedrus kasparyani Tselikh was described by Tselikh in 2013 from Russia and the male specimen of Synedrus kasparyani Tselikh is described for the first time, collected from Jammu & Kashmir, India, and the genus Synedrus Graham is recorded first time from India.
