( Figs. 9 , 34 )

Type material. HOLOTYPE: ♁, ‘ Peru:Dept. Cuzco, Sta.Isabel, Valley of River Ccosnipata , 30.xi.1951, F.Woytkowski ( USNM).

Description. Male (holotype). Dorsal coloration. Head black with short, yellow, longitudinal stripe between ocelli and postocular tubercle; antennal segments I to IV black; clypeus black; juga black with inner margin yellow; pronotum yellow with each margin black; anterior and posterior border yellow; anterior lobe of pronotal disk with transverse black stripe near middle third; posterior lobe with three longitudinal black stripes, lateral ones shorter than median stripe which reaches posterior margin of anterior pronotal lobe; scutellum yellow; clavus black; corium black with posterior half of costal border, claval margin, apical margin, and apical angle yellow; hemelytral membrane black; connexivum yellow with anterior third black; abdominal tergites III to VI black with yellow rectangular mark on middle third, and VII entirely black.

Ventral coloration. Head yellow, with posterior margin and longitudinal stripe on middle third black; rostral segments reddish brown; pro-, meso-, and metapleura yellow with two elongate black spots, one near anterior margin, other on middle third; prosternum and metasternum yellow; mesosternum yellow, lateral margin black; anterior and posterior lobes of metathoracic scent gland peritreme black; legs dark reddish brown; abdominal sternites III to V yellow with anterior margin black except middle third yellow; sternites VI and VII yellow with anterior margin entirely black; pleural margin yellow with anterior third black; abdominal spiracles yellow; genital capsule black with posteroventral margin yellow.

Structure. Head. Rostrum reaching posterior border of mesosternum; rostral segment I almost reaching apex of head; rostral segment II shorter than IV. Pronotum. Collar present; frontal angles rounded, not exposed; humeral angles obtuse, not expanded. Hemelytra. Macropterous, extending beyond apex of last abdominal segment. Legs. Femora ventrally armed with a single row of numerous small spine-like teeth; hind tibiae with outer dilation phylliform, without prominent teeth or emarginations; inner dilation straight, sinuate, not expanded ( Fig. 9 ). Genital capsule. Posteroventral border sinuate, without mesial concavity.

Measurements (mm). Body length 13.00. Head length including apex of clypeus 1.36; width across eyes 2.04; interocular distance 1.00; interocellar distance 0.37; length of antennal segments: I – 2.56, II – 2.92, III – 2.48, IV – 5.32. Pronotum length 2.56, maximum width across humeral angles 3.80. Scutellar length 1.92, width 1.60.

Female. Unknown.

Differential diagnosis. This species resembles S. tibialis , and S. pucalpa sp. nov. by having the hemelytral membrane dark brown to black, the antennal segments I to III as well as the fore, middle, and hind tarsus entirely dark reddish brown to black, and the anterior and posterior lobe of metathoracic scent gland peritreme black.

In S. saphes sp. nov., the connexival segments III to VII and the pleural margins of abdominal sternites III to VII are yellow with the anterior third black. In the other two species they are yellow with the posterior third black. The head dorsally and the trochanter are black in S. saphes sp. nov., and yellow to shiny orange in S. pucalpa sp. nov. and S. tibialis .

Etymology. From the Greek ‘ saphes ’, meaning distinct, referring to the distinctly delimited color pattern on head and trochanter; adjective.

Distribution. Only known from Peru (Cuzco).
