description: Species Naddia sp.    
 Material Examined. (Female): glued on cardboard point with labels as follows “ INDIA, West Bengal, Nadia, Kalyani, University of Kalyani campus [22°59'14.3"N & 88°27'03.5"E], alt. 11 m, 3.Aug.2023,Arnob Chakrovorty” “ Staphylinidae, Staphylininae, Staphylinini, Staphylinina, Naddia sp. ” (iForNature—Nature Club Educational Collection).   
 Diagnosis: Base colouration of the body black, including the head, thorax, elytra and antenna, legs are dark rufous brown. Few long black setae are present throughout the body. Body covered with golden-yellow pubescence. Measurements (mm): TL 186, HL 3.68, HW 3.9, PL 3.19, PW 3.28, EL 3.89, ELS 2.2, EW 4.05,   
Head (Fig. 1). Dorsal surface of the head is coarsely punctured, base of the head is deeply emarginated forming distinct dorso-lateral lobes. Head width greater than head length.  
 Antenna. 11 segmented, scape and 3 rd antennomere subequal. Long yellow setae present, the setation frequency and length both decrease towards the penultimate antennomere. The width of the antennomeres increases gradually from 3 rd to 11 th.   
Legs. Coxa deep brown-black, trochanter and femur reddish-brown, tibia and tarsomeres are darker than the femur. Trochanter to last tarsomere with dense yellow pubescence. Tarsal claw simple. Tarsal formula 5-5-5. Tibia bears two simple thick spurs with longitudinal striations at the distal end. Tibia bears short blunt bristles, additionally foreleg tibia bears golden-yellow pubescence.  
Pronotum. Anterior margin of the pronotum near the hamuli is moderately pointed, no secondary projections along the lateral margin, the posterior margin is ovoid. Dorsal surface of the pronotum has coarse and fine punctures. Prosternal area has a raised median ridge, setose. Coxal cavity is deep.  
Elytra. Elytra bears short white and golden-yellow pubescence along with long black pubescence throughout the dorsal surface. An ovoid patch of small hairs near the mid-lateral region, gives an appearance of a distinct oval marking on each elytra touching the lateral margin, the posterior margin bears a thick dense patch of golden-yellow pubescence pointing towards the dorsum.  
Abdomen. Tergite III and IV shiny, coarsely puncture near anterior and posterior margins and densely setose bearing long black setae, the lateral margin bears a triangular patch or golden-yellow pubescence, pointing towards dorsum, and few long greyish-black bristles. Tergites III–VI are coarsely punctured. Tergite V and VI has golden-yellow pubescence, which thickens along the lateral margins and bears few black stiff setae along the mid transverse line of each segment. Tergite VI and VII bears a thick patch of reddish-brown pubescence nears the posterior margin of each segment. The sternites have golden-yellow pubescence, not very dense, along with few stiff black setae. Sternite VI and VII are black with a thin band of brown colouration along the posterior margin and a thin patch of reddish-brown pubescence, but not as dense as the tergites.
