Two new species ofHedychrumLatreille from the Middle East and Pakistan (Hymenoptera: Chrysididae)

Two new species of Hedychrum Latreille (Hymenoptera: Chrysididae) from India and Nepal with review of the genus distribution in Asia

“…In India only four species have been recorded so far: H. flammulatum Smith, 1858, H. lugubre Cameron, 1897, H. timidum Dahlbom, 1854(du Buysson, 1896Bingham, 1903) and H. gracilentum Mocsáry, 1911. In Pakistan only two species are known: H. linsenmaieri Rosa, 2019(H. timidum sensu Bingham (1903 and du Buysson (1904)), and H. lama du Buysson, 1891(Nurse, 1904, whereas any species was recorded for Nepal. Kimsey and Bohart (1991) listed nine species for the Oriental region: H. flammulatum Smith, 1858, H. formosanum Mocsáry, 1911, H. lugubre Cameron, 1897, H. philippinum Mocsáry, 1913, H. stantoni Ashmead, 1904, H. striatum Mocsáry, 1911, H. taiwanense Tsuneki, 1970, H. takasago Tsuneki, 1970, and H. timidum Dahlbom, 1854 More recently, Rosa et al (2014) listed twelve species for the Palaearctic part of China (H. chalybaeum Dahlbom, 1854, H. davidi du Buysson, 1900, H. gerstaeckeri Chevrier, 1869, H. gracile Semenov, 1967, H. japonicum Cameron, 1887, H. latitudum Linsenmaier, 1959, H. longicolle Abeille de Perrin, 1877, H. manchurianum Tsuneki, 1950, H. niemelai Linsenmaier, 1959, H. nobile (Scopoli, 1763, H. simile Mocsáry, 1889, H. sinicum Semenov, 1967 and only three for the Oriental part (H. formosanum, H. taiwanense, H. takasago).…”

“…The genus Hedychrum Latreille, 1802 includes about 130 species with conservative habitus and morphological features (Kimsey & Bohart, 1991;Rosa, 2019). Most members of this genus are characterized by large and robust habitus; scapal basin deeply concave, with transverse cross-ridges; metanotum usually rounded, rarely mucronate; mesopleuron rounded, with indistinct omaulus and short scrobal sulcus; mid-and hind tibial pits; enlarged hind femur, sexually dimorphic, with anterior surface reticulate and non-metallic brown in males, and shiny metallic in females; tarsal claws apically bifid, because of a subsidiary inner tooth, subparallel to apex; fore wing medial vein slightly curved, stigma apically acute; third metasomal tergum with lateral tooth, apically swollen and only rarely with median notch or teeth; third metasomal sternum apico-medially more or less modified in females.…”

“…Species with non-metallic metasoma (e.g. H. zenobia Rosa, 2019), as in the H. roseum species group, are also known.…”

An annotated and illustrated checklist of the Indian cuckoo wasps (Hymenoptera: Chrysididae)

“…After Bingham and du Buysson, another important researcher was Nurse (1902Nurse ( , 1903aNurse ( , b, 1904Nurse ( , 1914, who deeply contributed to the knowledge of chrysidids of both India and Pakistan. From then on, only a few articles with occasional descriptions of new species of Indian chrysidids or simple records can be found in the literature (du Buysson 1893(du Buysson , 1898a(du Buysson , b, 1900Cameron 1897Cameron , 1902aMocsáry 1889Mocsáry , 1911Mocsáry , 1912aMocsáry , b, 1913Mocsáry , 1914Kurian 1955;Krombein 1957;Linsenmaier , 1997Jonathan et al 1977;Bohart 1988a, b;Kimsey 1988;Strumia 1996;Rosa 2018Rosa , 2019a, and a few citations on local faunas (e.g. Sihag 1983;Roy & Kundu 1985;Kadirvelu 1991;Mathew et al 1998;Suresh et al 1999;Mathew 2004;Anbalagan et al 2015;Thakkar & Parikh 2018;Johnson & Kunchithapatham 2019;Ahmed et al 2020).…”

A new species and new records of cuckoo wasps from Pakistan and India (Hymenoptera, Chrysididae)

“…Ants and Cuckoo-wasps'. Since then, only sporadic descriptions of new species, or new distributional records, were published by Linsenmaier (1959Linsenmaier ( , 1968Linsenmaier ( , 1997, Rosa (2018bRosa ( , 2019 and Rosa et al (2021).…”
