Etymology. This species is named after its elytral maculation.
Type locality. Mount Shikengdong ( Ƃ坑崆), Guangdong Province, China.
Diagnosis: Punctaltica maculata sp.nov. can be differentiated from P.shenzhenensis by the following characters: dorsum yellow brown with three black spots (uniformly black brown to yellow brown in P. shenzhenensis ); receptacle of spermatheca with external side straight, internal side slightly convex (external side straight to slightly convex and inside side convex in P. shenzhenensis ) ( Fig 2K View FIGURE 2 ); aedeagus narrowing from apical fourth to apex (narrowing from apical third to apex in P. shenzhenensis ).
P. maculata sp.nov. is distinguished from P. montana by the following characters: dorsum yellow brown with maculation and lacks metallic luster (black brown to yellow brown, with slight blueish luster in P. montana); middle area of metaventrite with approximately 23–27 setiferous punctures ( 60–70 in P. montana) ( Fig. 4G–I View FIGURE 4 ); antennomere III relatively short, length 1.30 as long as width (longer in P. montana, length to width ratio: 3.46) ( Fig. 4E–F View FIGURE 4 ); aedeagus with apex slightly bent ventrally (strongly bent ventrally in P. montana); aedeagus widest at the apical third (widest at middle in P. montana) ( Fig. 2F View FIGURE 2 ); apical spur of metatibia moderately developed (longer in P. montana) ( Fig. 4A–C View FIGURE 4 ).
General morphology ( Fig. 2A–D View FIGURE 2 ). Dorsum yellow brown and ventrum yellow brown to chestnut brown, without metallic luster; each elytron with a large black maculation at anterior 1/2, elytral suture with a longitudinal black maculation at middle. Body oval in dorsal view, strongly convex in lateral view. Head nearly invisible from dorsal view. Body length: 2.48–2.50 mm (n=2), width (widest point of elytra): 2.00– 2.12 mm (n=2), height: 1.44 mm (n=1). Body length to width ratio: 1.18–1.24 (n=2); body length to height ratio: 1.74 (n=1).
Head ( Fig. 3A View FIGURE 3 ). Surface yellow brown, glabrous, punctures absent on vertex; interantennal space wide, flat; width of interantennal space to antennal sockets ratio: 3.08 (n=1); approximately 16 large setiferous punctures present on frons. Each side of frons with a deep and wide groove (i.e., antennal groove) for accommodating antennae. Antennal calli poorly delimited; supracallinal sulci absent, midfrontal sulci barely visible to absent; supraorbital sulci moderately developed, supraorbital and supraantennal sulci oblique. Labrum flat, with two pairs of setae, apical maxillary palpomere conical. Distance between eyes (just above antennal sockets) to transverse diameter of eye ratio: 2.60–2.94. Longitudinal to transverse diameter of eye in frontal view, ratio 1.78–1.95 (n=2).
Antennae clavate, yellow brown, 0.30 times as long as body( Fig. 4F View FIGURE 4 ). Antennomeres 1–6 sparsely setose, 7–11 densely setatose. Antennomere I robust, clavate, as long as next two combined. Antennomere II slightly longer than III; antennomere III as long as next two combined; antennomeres gradually widened from sixth to tenth, widest at tenth. Length to width of antennomere III, ratio 1.30 (n=1). Length of antennomeres from I to XI, ratio 1: 0.63: 0.44: 0.31: 0.31: 0.25: 0.19: 0.25: 0.38: 0.88.
Thorax ( Fig. 3D View FIGURE 3 ). Pronotum length: 0.74 mm, width: 1.59 mm, pronotum length to width ratio: 0.46. Pronotum width at base to that of apical width ratio 1.65 (n=1). Pronotum glabrous, with very sparse minute punctures, without transverse or longitudinal impression, pronotal base evenly convex. Two sensory pores present on each side near lateral margin ( Fig. 2J View FIGURE 2 ). Lateral margin of pronotum moderately explanate, slightly convex. Anterolateral callosity of pronotum well developed, disproportionately long, occupying major part of lateral margin (extending from anterior end to posterior 1/3), with a setiferous pore situated at posterior 1/3 of lateral margin, the pore with a single long seta at middle. Posterolateral callosity poorly developed, with a setiferous pore, not protruding laterally beyond lateral margin.
Intercoxal prosternal process wide, ventral surface strongly concave in middle, laterally on either side with 4–6 punctures, width between procoxae to length of procoxa ratio: 0.95 (n=1). Antennal grooves present on each side to accommodate antennae. Posterior end of intercoxal prosternal process forming an elevated ridge.
Mesoventrite: Most of mesoventrite invisible in ventral view.
Metaventrite ( Fig. 4I View FIGURE 4 ): Metaventrite flat, with approximately 23–27(n=2) setiferous punctures present at the middle, puncture diameter to metaventrite length ratio: 0.08–0.13 (n=1); metaventrite surpassing the anterior margin of mesocoxae, covering the majority of mesoventrite. Prosternum tightly locked with mesoventrite (promesothoracic interlocking).
Elytra ( Fig. 2A View FIGURE 2 ). Humeral calli and hind wings absent. Impressions or ridges on elytra absent. Two symmetrical large black maculations, one on each elytron, extending from basal 1/6 to middle; a pair of longitudinal black stripes present on each side of middle of elytral suture. Scutellum present, small, triangular. Epipleuron widest at middle, gradually narrowing from middle to apex, basally wider than apically. Elytral apex rounded, covering entire abdomen. Elytra length: 2.07 mm, single elytron width (in dorsal view): 1.06 mm, length to width (double elytra) ratio: 0.98 (n=1). Length of elytra to pronotum, ratio 1.30.

Leg ( Fig. 4C View FIGURE 4 ). Apical spur of metatibia relatively long and strong. Claws simple. Dorsolateral margin of metatibia apically with numerous denticles. Length to maximum width of metafemur, ratio 1.37–1.44 (n=2). Length to width of metatibia in lateral view, ratio 4.58–4.67 (n=2). Length of metatibia to first metatarsomere, ratio 5.83– 6.21 (n=2). Length of metafemur to metatibia, ratio 1.31–1.36 (n=2). Width of metatibia at base to that at apex, ratio 0.42–0.48 (n=2).
Genitalia ( Fig. 2F–I View FIGURE 2 ). Aedeagus flattened dorsoventrally, strongly curved ventrad in lateral view, greatest curvature at middle. Apex of aedeagus rounded, apical denticle absent. In ventral view, sides of aedeagus almost parallel-sided, widest at apical 1/3, narrowed from apical 1/3 to apex. Length of aedeagus: 0.81 mm (n=1), width of aedeagus (at apical third): 0.21 mm (n=1), length to width ratio 3.86 (n=1).
Receptacle of spermatheca more or less cylindrical, with external side (i.e., the right side in Fig. 2K View FIGURE 2 ) straight to slightly concave, internal side slightly convex (i.e., the left side in Fig. 2K View FIGURE 2 ). Spermathecal pump narrower than receptacle, with a near-right-angled curve, as long as 2/3 of receptacle. Spermathecal duct not coiled, strongly bent towards receptacle. Vaginal palpi fused at base, length to width ratio: 1.36. Vaginal palpus: wide at base, strongly narrowing towards apex, width of base 3–4 times apical width ( Fig. 2L View FIGURE 2 ).
