Diagnosis
Maladera kishi sp. nov. is in external morphology very similar to M. haniel sp. nov. and differs by the lack of a tubercle on abdominal sternite III as well as by the shape of parameres: the fused parameres (distal aedeagal process) is simply pointed and not bifurcate, while the lateral process on the left side is more robust.
Etymology
The new species is named for Suresh Benjamin’s daughter, Kishi P.L. Benjamin (noun in apposition).

Description
MEASUREMENTS. Length: 9.2 mm, length of elytra: 6.6 mm, width: 5.2 mm. HABITUS (Fig. 4H) AND COLOURATION. Body short oval, dark brown, antenna yellow, dorsal surface shiny, finely densely setose.
HEAD. Labroclypeus short and trapezoidal, wider than long, widest at base, lateral margins strongly convex and convergent to widely rounded anterior angles, lateral border and ocular canthus producing an indistinct blunt angle, margins weakly reflexed, anterior margin not sinuate medially; surface slightly convex, finely and densely punctate, distance between punctures smaller than their diameter, with numerous erect setae in larger punctures; frontoclypeal suture indistinctly incised and bluntly bent medially; smooth area in front of eye approximately three times as wide as long; ocular canthus long and narrow, minutely and superficially punctate, without a short terminal seta. Frons with fine, dense punctures, with a few long erect setae in larger punctures. Eyes large, ratio of diameter/interocular width: 0.81. Antenna yellow, with ten antennomeres; club with three antennomeres, little longer than remaining antennomeres combined. Mentum elevated and anteriorly flattened.
PRONOTUM. Wide, widest at base, lateral margins in basal half straight and weakly convergent, in anterior half weakly convex and narrowed to anterior angles, anterior angles moderately produced and sharp, anterior marginal line fine and complete, anterior margin convexly produced medially; surface finely densely punctate, with moderately dense, short and fine setae and dense long erect setae being directed anteriorly; anterior and lateral borders sparsely setose, basal margin without marginal line; hypomeron ventrobasally carinate and slightly produced ventrally. Scutellum short and wide, triangular, with fine and dense punctures, with short, dense, fine setae.
ELYTRA. Short oval, widest shortly behind middle, striae distinctly impressed, finely and densely punctate, intervals weakly convex, with moderately fine, dense punctures and with dense, fine, short setae as well as with sparse long erect setae; epipleural edge fine, ending at the weakly convex external apical angle of elytra, epipleura densely setose; apical border narrowly membranous, apex covered with short microtrichomes.
VENTRAL SURFACE. Shiny, thorax and metacoxa with large and dense punctures, sparsely setose, metacoxa with minute adjacent setae in the punctures except for numerous long setae laterally, apical margin weakly convex, without a wide rim of long white microtrichomes; each abdominal sternite, in addition to evenly distributed fine and dense punctures bearing each a fine seta, with a distinct transverse row of coarse punctures each bearing a long and more robust seta, penultimate sternite apically with a shiny smooth chitinous border, which is a quarter as long as the sternite. Mesosternum between mesocoxae as wide as mesofemur, with a semi-circular ridge bearing robust setae. Ratio of length of metepisternum/ metacoxa: 1/1.8. Pygidium moderately convex, moderately finely and densely punctate, without smooth midline, punctures with short and dense, adjacent setae as well as with dense, long, erect setae.
LEGS. Short and wide; femur with two longitudinal rows of setae, finely and densely punctate; metafemur shiny, anterior edge acute, lacking an adjacent serrated line, ventral surface densely punctate and setose, posterior ventral margin straight, only little widened in apical half, finely indistinctly serrate apically, dorsally not serrated, glabrous. Metatibia short, widest at middle, posteriorly only very slightly narrowed, ratio width/length: 1/2.4, dorsally sharply carinate, with two groups of spines, basal well behind middle, apical one at four fifths of metatibial length, basally beside dorsal margin with two single punctures with serrated margins, each bearing a single robust spine and beside them a longitudinal serrated line; lateral face almost flat, with dense, large punctures and with fine setae in the punctures; ventral margin with five strong spines equidistant from each other, medial face smooth, apex interiorly near tarsal articulation shallowly concave. Meso- and metatarsomeres finely and sparsely punctate but glabrous dorsally, ventrally with sparse, short setae; metatarsomeres ventrally with a strongly serrated ridge, beside which is a strong longitudinal carina; first metatarsomere little shorter than following two tarsomeres combined and as long as dorsal tibial spur. Protibia short, bidentate. All claws symmetrical, feebly curved and long, with normally developed basal tooth.
