Remarks

• Systematics: Pulvinaria kalyaniensis., P. aligarhensis and P. ixorae are similar in having marginal setae with clubbed or capitate apices, an important character state that distinguishes them from other species of Pulvinaria. P. kalyaniensis resembles P. aligarhensis, which occurs on the same host plant, Azadirachta indica, in having multilocular pores mostly each with 10 loculi and in the distribution of preopercular pores on the dorsum. However, P. kalyaniensis is easily distinguished from P. aligarhensis by the following combination of features (character states of P. aligarhensis in parenthesis): (i) submarginal tubercles present (absent); (ii) dorsum with areolation (without areolation); (iii) two types of marginal setae (one type); and (iv) dorsal tubular ducts present (absent). P. kalyaniensis also resembles P. ixorae, which occurs on a different host (Ixora coccinea, Rubiaceae), in having submarginal tubercles and dorsal tubular ducts. However, P. kalyaniensis differs from P. ixorae by the following combination of features (character states of P. ixorae in parenthesis): (i) multilocular pores each with 5‒13 loculi, mostly 10 (7 or 8 loculi); (ii) 5 pairs of prevulvar setae (3 pairs) and (iii) derm without reticulate pattern (with reticulate pattern). (Talukder & Das, 2021)
• Structure: Body of adult female elongate oval with dorsum convex; body colour varies with age, generally yellowish green with dark brownish markings on dorsum but with one characteristic median longitudinal yellowish green stripe. Ovipositing females each produce a white ovisac from beneath the abdomen, the body becoming lifted posteriorly by expansion of the ovisac. Ovipositing females become darker and the body surface develops very light wax deposits. The eggs are light orange and nymphs are creamy white; after hatching they settle on the lower leaf surfaces, mostly along the midrib and other major veins. Slide-mounted adult female oval to broadly oval; 2.5‒3.4 mm wide, length 1.6 times maximum width. (Talukder & Das, 2021)
• Biology: Adult females form colonies on twigs
• Economic Importance: Due to the heavy infestation, sooty mold had developed on honeydew deposits on the upper leaf surfaces nearby but no sign of any other damage was found in the tree. (Talukder & Das, 2021)
