Remarks
Moser (1920: 16) based his description of M. seriepunctatus on an unstated number of specimens. The single ZMHB syntype is therefore designated as lectotype in order to enhance the stability of nomenclature and fix the specimen I based my redescription on, in case other syntypes are discovered in the future.
Description
MEASUREMENTS. Total body length 6.80 mm (lectotype).
Dorsum and venter uniformly castaneous brown. Frons convex dorsally between compound eyes, subopaque dorsally and ventrally. Male labroclypeus ( Fig. 174 View Figs 169–180 ) broadly shallowly emarginate anteriorly, its lateral margins sinuous in both dorsal and lateral views. Anterolateral angles rounded, slightly protruding, raised up at angle of nearly 95° to frons in lateral view. Anterior and lateral margins of labroclypeus smooth. Upper- and underside of labroclypeus with sparse moderately long setae along anterior and lateral margins. Canthus nearly straight in dorsal view. Punctures of frons ovoid, moderately large, rather flat. Intervening spaces microreticulate, variably large. Head setae scale-like, appressed to suberect, those along internal margin of compound eye surpassing length of corresponding punctures, those on labroclypeus, most of frons and vertex minute, rising from anterior margin of corresponding punctures, not surpassing their length. Antenna 9-segmented, club 3-lamellate. Pronotum transverse, flattened dorsally, subopaque dorsally and laterally. Anterior margin of pronotum broadly emarginate with protruding anterolateral angles, basal margin broadly rounded. Lateral margin of pronotum broadly rounded, delicately crenulate all along ( Fig.251 View Figs 242–258 ).Lateral margin of pronotum sinuous in lateral view.Short thickened suberect seta present between every two crenulae. Lateral margins, antero- and posterolateral angles completely covered with microscopical velvety pubescence. Hypomeron emarginate and long setose on anterior margin which is flange-like ( Fig. 280 View Figs 278–285 ). Antennal pocket deep. Pronotal punctures ovoid, deep and dense, intervening spaces glossy, larger than punctures on anterior half, smaller than those on posterior half of disc. Setae minute, arise from anterior margin of corresponding punctures, not surpassing length of punctures. Scutellar shield rounded apically. Elytron subopaque, without tracks of longitudinal carinae. Elytral punctures elongate, dense and deep, arranged in irregular longitudinal rows ( Fig. 342 View Figs 333–348 ). Intervening spaces glossy, generally smaller than punctures, in part wrinkled. Elytral setae inconspicuous, scale-like, appressed; seta rises from anterior margin of each puncture, generally not surpassing length of corresponding puncture. Some longer scale-like clavate scattered over disc and especially abundant along lateral sides. Male pygidium flattened dorsally, very vaguely medially longitudinally impressed, with dense rather deep ovoid punctures (Fig. 522). Intervening spaces glossy, variably large. Setae of pygidium scale-like, in part clavate, sparse, suberect, those on distal half longer than corresponding punctures. Male protibia widened distally, with two obtuse external teeth (Fig. 414). Male protibial terminal spur straight. Male metatibial terminal spurs long, subequal, pointed. Tarsal claws with pulvilli (in male only?).
Sexual dimorphism
Female is unknown.
