Description of the male. ( Figs. 5–6 , 15 ). Alar expanse 21 mm, forewing length 9 mm, antenna 6.5 mm, body length 12 mm. Head with white labial palp; second and third palpomere laterally with a narrow, black stripe; frons pale grey with purple tinge, dorsally pale yellow, adjacent to the eye white; vertex black, between antenna and ocellus a patch of short, silver-white scales; pericephalic scales yellow, dorsally mixed with black, laterally white; antenna black, scape ventrally and a longitudinal stripe at posterior side of flagellum white. Thorax dark brown, dorsally mixed with black; patagia anteriorly with some pale yellow scales and laterally with a small, white spot; meso- and metathorax laterally with some white scales; mesothorax dorsally with 3 narrow, yellow, longitudinal stripes; inner border, anterior and posterior part of tegula, as well as dorsolateral scale tufts of metathorax bright yellow; scapular spot medially with some whitish scales. Abdomen brownish-black; posterior margin of tergites 1 and 4 with some white scales; tergites 2–7 medially dusted with a band of coloured scales that are bright white on tergites 2, 4, 5, and 7, but scarcely white on tergite 6, and bright orange-yellow on tergite 3; sternites 4–7 medially whitish; posterior margin of each segment laterally white; anal tuft brownish-black, dorso-distally and ventrally white; lateral side of valve pale yellow. Forecoxa white, proximally with a black, medial spot and distally with some black scales; foretibia dorsally brownishblack, medially with some white scales, ventrally pale yellow, lateral scale tuft almost white, dorsally pale yellow. Mid- and hindleg with brownish-black coxa and femur, the latter dorsally yellow, mesally and a small latero-distal patch white, ventrally with dense, white, hair-like scales; tibia brownish-black, laterally and dorso-laterally orange-yellow except for a brownish-black proximal and medial part, ventral side medially white; tarsi of all legs brownish-black and distally with a narrow white ring; lateral spurs white, mesal spurs dorsally brownish-black, ventrally white. Wings black with well-developed transparent areas; forewing with longitudinal transparent area reaching discal spot; apical area absent; discal spot and margins narrow; subcosta, cubitus stem and veins of external transparent area marked with some white; hindwing with discal spot very short, triangular; costal margin whitish; fringes of all wings dark grey, except for white anal angle of hindwing.

Variation. A presumably freshly emerged female specimen in the TMPS has bright yellow rather than white markings and narrow yellow apical area ( Fig. 9 ). As in other sesiid species (e.g., Chamaesphecia ), the yellow colour of these areas is bleached out in older specimens.

Redescription of the female. ( Figs. 7–9 , 16 ). Alar expanse 25 mm, forewing length 16 mm, antenna 7 mm, body length 14 mm. The female is rather similar to the male, but with more intense colouration and instead of white, ventrally yellowish and dorsally orange-yellow. Head with vertex with mixed black and bright orange; pericephalic scales dorsally orange, laterally yellowish to white; antenna almost black, except for some white scales apically. Thorax black, marked with orange-yellow, in particular posterior part of tegula and ventro-lateral scale tufts of metathorax. Abdomen black, tergites 1–6 with a broad, orange-yellow band that is somewhat darker orange on tergite 3 and medially interrupted with black on tergites 2 and 3; sternites black, posterior margins as well as a large, triangular, anteriorly narrowed, lateral spot whitish-yellow; tip dorsally with an orange-yellow spot on each side. Foreleg with coxa yellowish-white to yellow, proximally with a black, medial spot; femur dark brownish-grey, distally with some yellow scales and white hair-like scales at ventral edge; tibia whitish-yellow with yellow lateral scale tufts, dorso-medially white, proximally and sub-distally black; tarsus ventrally whitish. Other legs with coxa and femur black, the latter ventrally with dense, white, hair-like scales; tibia dorsally orange-yellow, dorso-proximally black, meso-proximally white, meso-distally black, lateral and ventral side proximally and distally black, medially white; tarsi of all legs black, each tarsomere distally with a narrow white ring, first hindtarsomere tufted with long black scales. Wings as in male.

Diagnosis. The female holotype of Crinipus marisa is slightly damaged and heavily descaled, its body colouration almost lost. Additional specimens here considered to belong to C. marisa are another female specimen in the BMNH, which is from Johannesburg and also has medially somewhat rubbed-off tergites, as well as two females and three males in the TMPS, which are from South Africa. All specimens in the TMPS were previously misidentified as C. vassei , which is rather similar in size and body shape to C. marisa , but differs distinctly by the following characteristics: legs and body marked almost bluish-white (yellow-orange in C. marisa ); forewing discal spot nearly as wide as widest part of anterior transparent area (distinctly narrower in C. marisa ); tergites 3–6 (7) laterally with a large white spot (with a white or orange-yellow dorsal bar in C. marisa ). The male genitalia structures are very similar in C. marisa and C. leucozonipus , but the latter has a more triangular valva and fewer simple, non-bifurcate setae on the crista sacculi. The male of C. vassei and the female of C. pictipes are unknown, and the female genitalia of C. leucozonipus were not examined. The female of C. marisa differs from that of C. vassei by the more pointed papillae anales, the longer finger-like protrusion of the ostium, the stronger and broader sclerotization of the antrum, and the angled ductus bursae. See remark for C. pictipes .
