New species, new records and re-description of spider mites (Acari: Tetranychidae) from India

Abstract

Two species of Tetranychidae (Acari), Oligonychus neotylus sp. nov. from Zea mays and Pennisetum purpureum (Poaceae) and Tetranychus hirsutus sp. nov. from Gymnema sylvestre R. Br. (Apocynaceae) are described from Karnataka state, south India. Tetranychus bambusae Wang and Ma is recorded for the first time from India and re-described. Four other species are reported for the first time from India viz., Oligonychus coniferarum (McGregor), Oligonychus duncombei Meyer, Tetranychus marianae McGregor and Tetranychus okinawanus Ehara from Cupressus sp., an undetermined grass, Centrosema pubescens and Adenium obesum, respectively.

The genus Oligonychus Berlese (Acari, Prostigmata, Tetranychidae): taxonomic assessment and a key to subgenera, species groups, and subgroups

“…Thus the setae are named as one pair of clunals and two pair of para-anals, and as a consequence, the statement "one pair of para-anal setae is present in Oligonychus and related genera" appears to be contradictory to what other authors believe. Many authors also mention the presence of h 1 and only one pair of para-anal setae (either h 2 or h 3 ) in the genus diagnosis and descriptions/illustrations of different Oligonychus species (Rimando 1962;Tuttle and Baker 1968;Chaudhri et al 1974;Meyer 1974;Jeppson et al 1975;Tuttle et al 1976;Zaher et al 1982;Tseng 1990;Gupta and Gupta 1994;Smiley and Baker 1995;Ehara 1999;Knihinicki and Flechtmann 1999;Flechtmann and Etienne 2006;Ehara and Gotoh 2007;Zeity 2015Zeity , 2016Alatawi and Kamran 2018).…”

Stethorini (Coleoptera: Coccinellidae: Coccinellinae) of South India: their associated mite species and barcode gap analysis

“…Species of Stethorini were identified based on available literature and taxonomic keys (Kapur 1948, 1961and Poorani 2017. Mite specimens were identified based on available species descriptions and taxonomic keys provided by Gupta (1985), Gupta andGupta (1994), Ehara (1995), Srinivasa et al (2012) and Zeity et al (2016).…”
