Aarvik 2860 ( LA); 533, same locality, 28–30.xi.2010, T. Gilligan ( TD); 1Ƥ, Mt. Elgon , viii.1954, T.H.E. Jackson, genitalia slide USNM 137,555 ( USNM).
Description. Adult. Male ( Fig. 18 View FIGURES 18 – 22 ). Head: Brownish black. Antenna brownish grey, scape white. Labial palpus 1,5 times diameter of eye, brown, intermixed with black scales, extreme tip white. Thorax: Dorsum and tegulae with narrow black edge in front, broad white band before middle and white posterior scale tuft. Fore and mid-legs dark grey, hind leg beige; fore and mid-tarsi with paler rings; fore and mid-tibiae with basal, medial and distal light dots; hind tibia with beige scale tuft, hind tarsi with grey rings. Wingspan 18.0–19.0 mm. Forewing black, suffused with brown in distal third, particularly in tornal area; costal strigulae white; dorsal maculae rounded, connected, outer macula with dark dots; tiny discal white dot; cilia grey, rather large white patch below apex. Hindwing light grey, with single cilia line.
Female ( Fig. 19 View FIGURES 18 – 22 ). Head: As in male. Thorax: Wingspan 21.0–22.0 mm. Labial palpus 2 times diameter of eye. Male genitalia ( Figs. 49, 50 View FIGURES 47 – 54 ). Cucullus rather slender, dorsal and ventral edge nearly parallel, sacculus shallowly concave between sacculus and cucullus, phallus ( Fig. 50 View FIGURES 47 – 54 ) of medium length, 607–676 μm., slightly tapering from beyond middle, ventral edge rugose, with 44–48 small cornuti. Tergite 8 ( Fig. 31 View FIGURES 23 – 33 ) very short, deeply incised laterally.
Female genitalia ( Figs. 70, 71 View FIGURES 68 – 71 ). Sternite 7 with narrow, deep U-shaped excavation; sterigma oval, extended posteriorly, weakly sclerotised on right side; ductus bursae with weak internal sclerite near ostium; the paired oval sclerites posterior of sterigma distinct, well separated from each other and posterior edge of sterigma.
Diagnosis. The male genitalia of D. gilligani are distinguished by the rugose ventral wall of the phallus, and the female genitalia by the elongate sterigma and separate oval sclerites.
Distribution. Kenya.
Biology. The habitat in Kenya is high elevation grassland and mixed scrub predominantly with leleshwa ( Tarchonanthus camphoratus L.) ( Asteraceae ) and some Acacia gerrardii Benth. (Fabaceae) .
Etymology. The species is named after Todd Gilligan, who collected a series at Gilgil, Kenya.
Remarks. A male from Malawi with the following data: Zomba District: Zomba Plateau, 15o22.010’S 35o18.959’E, 1470 m., 19–20.i.2006, A.J. Kingston, genitalia slide L. Aarvik 2838 (LA), was first identified as D. gilligani n. sp. However, in the COI neighbour-joining tree, this specimen (termed Dracontogena sp. B) and a specimen from Kenya herein described as D. gilligani n. sp. cluster together with specimens not thought to be D. gilligani n. sp. ( Fig. 78 View FIGURE 78 ).
