Etymology: Named after Ashley Kirk-Spriggs, who collected many Chyromyidae in Namibia.
Diagnosis: Yellow species with black ringed ocelli, elongate slender eyes, dark longitudinal scutal stripes, scut with dark lateral margin reaching base of subapical setae; abdomen yellow with light brown bands dorsally on tg; male postabdomen with large shiny dark brown phallic structures easily visible, owing to their contrast with yellow tg and st. Male postabdomen with setulose surs and prg, and bilobed distiph.
Description:
Male.
Head: fr, oc triangle and ocp entirely yellow, only ocelli black; eye narrow and horizontal, about 3 times as long as high; gena yellow and pale yellowish white setulose, about equal to height of eye; face very small and membranous with shallow linear carina; antenna including first segment of arista yellow, second aristal segment dark brown; mouthparts yellow. Chaetotaxy: 3 reclinate orb with short setula in front, 2 long ocellars widely spaced almost parallel, 10 fr setulae and a pair of long setae in front of oc triangle; 1 vti and 1 vte, pvt convergent.
Thorax: Scutum yellow and pale yellow pollinose with dark grey scutal stripes confluent anterior to transverse suture; scut yellow with brown lateral margin up to subapical setae; mtn dark and pleura yellow with dark greyish brown triangular mark on katepisternum and spot on meron. Chaetotaxy: 2+5 dc only hindmost developed to a seta, 0+4 acrs in two irregular rows, 1 pprn, 1 ihu, 1 posthu, 1 ia, 2 ntpl, 1 pa, 1 anepisternal and 1 katepisternal with a few setulae near each.
Wing: Hyaline with yellow veins becoming darker towards apex; distance between R 2+3 and R 4+5 about 0.5 that between R 4+5 and M 1+2; distance between crossveins equal to length of posterior crossvein. Haltere pale yellow.
Legs: No special modifications, yellow and yellow setulose, tarsomere 5 brown.
Abdomen: tg pale brown with yellow hind margins which occupy about 1/4 length of tg dorsally, but become broader on sides.
Postabdomen: cerc small yellow and pointed; distiph large shiny and dark.
Female.
Very similar to male; eye less elongated. (Postabdomen not dissected.)
Length: ơ body 1.1 mm, wing 1.0 mm; ^body 1.2 mm, wing 1.3 mm.
Variation: The male paratype has the eye only twice as long as high and the tarsomeres being all yellow.
