Holotype redescription

MEASUREMENTS. Length: 7 mm. Width: 3.75 mm.

HEAD. Black, surface with simple setae. Labroclypeus, shape of anterior margin weakly sinuated medially, posteriorly with sparse punctation. Ocular canthus with terminal setae, ratio to eye: 1/3. Eyes, ratio diameter/interocular width: 0.40. Antennae with eight antennomeres; antennal club with three antennomeres; ratio antennal club/remaining antennomeres: 1/1.5; ratio third vs fourth antennomere: 1/2; fourth antennomere, lateral projection absent; ratio fifth vs fourth antennomere: 1/5.

PRONOTUM AND ELYTRA. Surface of pronotum and elytra without setae. Pronotum bicolored, widest at base, anterior marginal line present, posterior marginal line absent, lateral margin weakly convex and serrated, antero-lateral angle dorso-ventrally flattened, postero-lateral angle dorso-ventrally not flattened, punctation on disc sparse, setae of lateral margin dense, median longitudinal excavation absent. Scutellum, punctures absent medially. Elytra unicolored, brownish-orange, surface opaque, microsculpture absent, punctation on intervals present, sparse, diameter of strial and interval punctation equal, posterior edge straight.

ABDOMEN. Lateral carina absent. Second visible ventrite without row of setae in medial region. Apical visible ventrite without suture to apical tergite.

LEGS. Ratio of length of metepisternum/metacoxa: 1/0.77. Metacoxa without longer lateral bristles, a laterally extended longitudinal shelf present. Metatibia, widest at apex, ratio of width/length: 1/3.34, dorsal margin carinated, ventral margin not serrated, distal spines groups disposed at two thirds of metatibial length. First metatarsomere, ratio to dorsal metatibial spur: 1/2. Dorsal surface of tarsi glabrous, without punctures. Metatarsi, length of first protarsomere subequal to second and third combined, ventral margin serrated and glabrous. Protibia with three teeth. Protarsi, length of first protarsomere subequal to second and third combined, second protarsomere narrow, claws symmetrical, inner protarsal claw bifid, apex of basal tooth of inner protarsal claw acute.

Remarks

There is no difference between female type specimens of S. abcora and S. apolinarmaria except coloration, which is very variable. Therefore, we consider them synonymous.
