D e s c r i p t i o n: Macropterous, black with a faint lustre, each elytron with a long, oval, slightly elevated orange spot in posterolateral quarter (fig. 39); punctuation coarse to very coarse, coalescent on pronotum and elytra; pubescence short, recumbent. Anten-
nae brownish, club infuscate. Maxillary palpi reddish brown. Paraglossae coniform. Legs reddish brown, apical portion of femora shortly infuscate.
Length: 6.8 mm (forebody: 3.4 mm).
PM of the HT: HW: 55.5; DE: 28; PW: 44; PL: 52.5; EW: 54; EL: 60; SL: 47; SpL: 23.
M a l e: Femora swollen, metatrochanter toothlike prominent (fig. 96), meso- and metatibiae each with a small preapical spine, metatibiae curved inwards. Metatsternum broadly and very deeply concave, punctuation slightly less coarse, distinctly more sparse than in S. bilunatus . Sternites 3-7 with very shallow median impressions, which are much denser punctate and pubescent than the sternites laterally, sternite 7 very shallowly emarginated apically. Sternite 8 apically with a moderately broad notch about one tenth as long as the sternite. Sternite 9 with a shap tooth apicolaterally. Tergite 10 broadly rounded. Aedeagus about as in S. bilunatus (fig. 65), the apicomedian excision of the expulsion clasp narrower and deeper (fig. 79, 91).
