Description. Female lectotype. Length 2.4 mm, width 2.7 mm; body oval, convex. Dorsal surface with head alutaceous, feebly shiny, pronotum and elytron smooth, shiny. Color yellow; pronotum with small, triangular, basomedial brown macula, macula not extended to anterior pronotal border, apex of macula narrow, emarginate with yellow medially; elytron black with 4 yellow spots, without humeral spot ( Fig. 130 ), mediolateral spot elongate oval; prosternum, meso–, metaventrites, and median area of abdominal ventrites 1–2 dark brown, abdominal ventrites 3–6 brownish yellow. Head punctures small, separated by diameter or less, each puncture as large as an eye facet; pronotal punctures equal in size to head punctures, separated by 1–3 times diameter; elytral punctures larger than on pronotum, separated by 1–3 times diameter; punctures on metaventrite large, separated by diameter or less medially, becoming larger, more dense laterally. Clypeus weakly emarginate apically, nearly truncate, lateral angle rounded. Eye canthus short, about 4 eye facets long, angled forward, apically rounded, brown. Pronotum narrowed from base to apex, lateral margin straight, basal angle broadly rounded, anterior angle abruptly rounded, basal margin without bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange rounded, outer margin with about 8 small teeth, sponda raised above protibial border. Abdomen with primary pores laterally between ventrites 4–5 small, round, extended under apical 1/4 of ventrite 4; postcoxal line on basal abdominal ventrite angled to apical margin, flattened along margin, rounded to apex, ventrite with sparse, long pubescence and sparse, coarse punctures medially; ventrites 2–4 sparsely pubescent, distinctly, densely punctured throughout; 5th ventrite flat, apical margin very slightly emarginate; 6th ventrite short, narrow, apical margin arcuate. Genitalia with spermathecal capsule strongly, evenly rounded, cornu enlarged; bursal cap with 3 arms, inner arm weakly sclerotized, median strut long, apically flattened in lateral view ( Fig. 135 ).

Male. Similar to female except pronotum with basomedial macula smaller, extended slightly more than 1/ 2 distance to anterior pronotal margin, apex distinctly emarginate with yellow medially, elytron with humeral spot. 5th ventrite depressed medially in apical 1/2, apical border weakly emarginate medially, lateral angle of emargination with small tubercle bearing tuft of dense setae; 6th ventrite narrow, deeply depressed medially, depression glabrous, without median tubercle, apical margin shallowly emarginate, angle on each side of emargination bearing tuft of setae. Apical tergite short, narrow, apex truncate, surface densely, finely punctured. Genitalia with basal lobe nearly as long as paramere, wide, sides weakly convergent, apex obliquely truncate; paramere Unm type, narrow, curved, weakly widened apically, apex rounded ( Fig. 131, 132 ); sipho robust, curved in basal 2/3, basal capsule with inner arm short, slender, apex slightly rounded, outer arm longer and wider than inner arm, straight, with accessory piece, basal border broadly, weakly emarginate ( Fig. 133, 134 ).

Variation. Length 2.0– 2.4 mm, width 1.6–1.8 mm. Pronotum of female with basomedial macula apically emarginate with yellow, as in lectotype, or apex evenly rounded.

Type locality. Colombia.

Type depository. UMZC (lectotype designated by Gordon 1987).

Geographical distribution. Colombia, Ecuador.

Specimens examined. 9. Colombia. The lectotype ; Monterredondo, Cundinamarca, Klmb. , 1400 m, leg. Schneble 1961, 20.7, 28.10 .; Monterredondo , Cundinamarca, 13. 11.1965, Columb. 1400 m . Ecuador. Napo, Misahualli , 1 o 02’S 77 o 40' W, X-27 to X-29 2002, E. M. Fisher. ( CSCA) ( USNM) .

Remarks. It is not often possible to place female types with males of the same species, but the lectotype of S. bisquatuorpustulata compares well with the Colombian specimens listed above in size, shape, elongate oval, mediolateral spot on the elytron, and Colombian locality. Therefore this specimen is considered to be S. bisquatuorpustulata .

A single specimen from Napo, Ecuador, is doubtfully placed here because the male genitalia compare well, but the mediolateral spot on each elytron is almost round. See remarks under S. arcualis .
