Antennal segments I and III yellow; IV yellow with pedicle light brown; V light brown on apical half; VII–VIII light brown; II and VI brown (Fig. 3). Legs yellow with reticulation. Fore wings light brown with three clear areas. Thorax light brown with brown shaded on lateral and ventral side. Abdominal segments brown; body setae light brown. Head broader than long with polygonal reticulation on dorsal surface with internal wrinkles within the reticules, cheeks convex; ocelli larger than any of the ommatidia (Fig. 4). Antennae 8-segmented; III and IV with a narrow apical neck and with forked sense cones; IV–VI with dense row of microtrichia; II–V each with long dark setae (Fig. 3).   
 Pronotum transverse; completely reticulated with internal wrinkles within the reticules; anteroangular and posteroangular setae absent (Fig. 4). Meso- and metasterna without spinula (Fig. 5). Meso- and metanotum without campaniform sensilla (Fig. 8). Mesonotum with median pair of setae far from anterior margin. Metanotum with median pair setae near anterior margin (Fig. 8). Fore wing with eight setae on upper vein, nine setae on lower vein; clavus with four setae; surface of wing completely covered by transverse rows of equal length microtrichia; posterior fringes wavy. Legs reticulated with numerous setae. Maxillary palps 1-segmented. Abdomen reticulated with internal wrinkles within the reticules; tergites I-II and XI completely reticulated; III–VIII with reticulation on anterior 1/3 rd; X without reticulation. Tergites III–VIII with arched sculpture laterally (Fig. 7). Tergite VIII with complete comb of microtrichia absent medially. Sternites with a row of discal setae near posterior margin (Fig. 9).

 Measurements. (holotype female in microns). Body length 1040. Dorsal head length 110, across cheeks 42; compound eye dorsal length (width) 66 (52); Pronotum median length (width) 93 (183). Fore wing length 610. Ovipositor length 226. Antenna length 283; segments I–VIII length (width): 19 (22), 33 (28), 36 (18), 32 (20), 42 (19), 28 (15), 14 (5), 40 (4).   
 Specimens studied. Holotype female, India, Thrissur, Kerala (N10.51, E76.36, 87m), from Asparagus racemosus, 02.i.2019 (Reg. No. 11285/H17) Iftikar Rahman, in The National Zoological Collections (NZC), Kolkata. Paratypes: 2 males, one female, all from same site as holotype (Reg. No. 11286/H17 to 11288/H17).   
 Etymology. This species is credited to Shivendra Kumar Singh for his keen interest in thrips collection and studies backing to his childhood.   
 Comments. According to the description and illustrations provided by Wilson (1975), the new species Oneilliella shivii differs from O. williamsi by having apical neck of antennal segment III shorter than IV (apical neck of antennal segment III longer than IV in williamsi); antennal segment II brown (brown in description of the species and yellow in left antenna illustration in williamsi); antennal segment III yellow (brown with apical neck white in williamsi); segment V with brown shade apically (V completely yellow in williamsi); all legs completely yellow (legs are dark brown except for extreme apex of tibiae and tarsi white in williamsi); fore wing light brown with three clear areas (fore wing uniformly brown with subbasal pale area in williamsi).
