Chinnamade Zeity & Srinivasa & Gowda, 2016 Zeity & Srinivasa & Gowda 2016 [151,412,1539,1565] Arachnida Tetranychidae Oligonychus GBIF Animalia Trombidiformes 1 Arthropoda species neotylus sp. nov.   General diagnosis.Based on Pritchard and Baker (1955), this new species belongs to the pratensisgroup defined by the aedeagus bent dorsad, and females with tibia I with nine tactile setae, tarsus I with two tactile setae on the venter at or just beyond the distal set of duplex setae, longitudinal striae between setae f1; they inhabit the under surface of monocotyledonous host plants. The species is defined by having: pre-genital striae longitudinal; striae transverse on posterior part of genital area, longitudinal anteriorly between g1. Peritreme ends in simple elongate bulb. Knob of aedeagus similar to bird’s head with beak.   Description. Male. Holotype. Near grayish in color.   Gnathosoma.Terminal sensillum of palpus (3.9–4.3µm) twice as long as broad; dorsal sensillum (3.8–4.0µm) fusiform, smaller than terminal sensillum (spinneret). Peritreme ends in simple elongated bulb.  Dorsum.Idiosoma length 390 µm (including gnathosoma), range 388–391 µm ( 2 paratypesproperly mounted and measured).

Like  Oligonychus tylus, the new species is not monophagous.  Oligonychus tylusis known from  Panicum maximum, Sorghumand an unidentified wild grass ( Poaceae), and also Phoenix dactylifera( Arecaceae) ( Baker & Pritchard 1960; Gerson et al., 1983; Sirsikar & Nagabhusanam 1986). 1701201046 2013-10 AINP Mahran Zeity India Doddaballapur 895 13.283334 Other 1291 77.53333 Zea 4 AINP1354 1 1701201043 2014-11 GKVK Mahran Zeity India 940 13.074166 Bangalore 21 77.57861 4 AINP1660 1 1701201047 [199,993,1315,1340] AINP Agricultural Acarology 4 1 holotype 1701201049 [1005,1258,1315,1340] UAS India Bangalore 4 1 holotype
