description: 3. Dragmatucha cochliana Park, sp. nov.   
(Figs 8 A–E)  
 Type material. Holotype: male, Uganda, Kasese Distr., Kibale Nat. Park, 19–24 xi 2014 [UTM:] 36N TF 0582 6208, 1,500 m, Leif Aarvik & Knud Larsen; gen. slide no. CIS-7192; COI Barcode CBNU083, in NHMO.   
 Diagnosis. This species is superficially similar to the preceding species, D. goniotes sp. nov., with similar wing pattern of both wings, but it can be distinguished by the larger size, the forewing more narrowly elongated with more oblique termen and the yellowish white postmedian band in the hind wing less sharply angled between veins R 3+4 and M 1. In addition, it can be distinguished from the latter by the male genitalia with cucullus more robust, half-moon-shaped, with more rounded outer margin; the juxta deeply concave on caudal margin, with triangularly produced latero-caudal lobes.   
 Description. Male (Fig. 8A). Wingspan 18.5 mm. Head: Yellowish white, with yellowish brown scales posteriorly. Antenna slightly shorter than forewing; basal segment elongated, dark brown dorsally, yellowish white ventrally; flagellum yellowish white throughout, sharply acute apically. Second palpomere of labial palpus thickened, long, more than twice width of compound eye, arched, pale yellowish brown, speckled with dark-brown scales on outer surface; 3 rd palpomere slender, strongly upturned, as long as 2 nd palpomere, yellowish brown on outer surface. Thorax: Tegula yellowish white, covered with yellowish brown scales anteriorly; thorax yellowish white with yellowish brown scales along anterior margin. Hind tibia yellowish white, with yellowish brown, rough scales medially. Forewing with dark brown sub-basal area; antemedian band broad, band-like, yellowish brown, slightly broadened toward costa and inner margin; area between antemedian band and postmedian band broad, about twice width of basal area; postmedian band linear, strongly angled inwardly on vein CuA 2; apex produced; termen oblique; fringe yellowish white, with yellowish brown median band; venation with R 1 arising before middle of discal cell; distance between origins of R 1 and R 2 about more than twice the length of R 2 and R 3; R 3 stalked with R 4+5 for more than basal 1/4; R 4 and R 5 stalked for about basal 3/5, R 5 reaching costa; M 1 remote from R 3+4 at base; M 2 approximate to CuA 1; M 3 merged to CuA 1; CuA 1 short-stalked with CuA 2; 1A+2A not forked; cell closed. Hind wing yellowish brown, much paler in basal 1/3; postmedian band similar to that of forewing, slightly angled outwardly on M 2; venation with M 2 well-developed, arising from near lower corner of cell; M 3 merged to CuA 1; CuA 1 connate with CuA 2 basally; CuP well-developed, arising from near middle of lower margin of discal cell. Abdomen (Fig. 8E): Spinous zones on dorsal surface broadly occupied; segment VIII simple.   
 Male genitalia (Figs 8C, D): Uncus slender, heavily sclerotized, nearly parallel sided, with acute apex, exceeding apex of basal plate of gnathos. Basal plate of gnathos narrowed in apical part, with rounded apex; median process strongly bent beyond middle, with sharply pointed apex. Tegumen sclerotized, deeply concave on anterior margin. Valva broad basally, narrowed toward cucullus; costa convex basally, then slightly oblique; ventral margin arched; sacculus weakly sclerotized, broad at base, then gradually narrowed, terminated at lower corner of cucullus; cucullus short, with rounded outer margin, densely setose. Juxta narrowed distally, concave on caudal margin with triangular caudal lobes laterally; median ridge weakly developed.Aedeagus stout, as long as valva, bent at basal 1/3; dorsal surface terminated with ladle-like plate, upturned; cornuti consist of a sole-like plate and much smaller one, and a large patch bearing numerous spinules in distal part.   
 Female unknown.   
 Distribution. Uganda (Kibale Nat. Park).   
 Etymology. This species is derived from the Latin, cochlear (= ladle, spoon), referring to the ladle-like dorsoapical plate of the aedeagus in the male genitalia, with a Latin suffix, - ana. It is a noun in the nominative case.
