LSID: urn:lsid:zoobank.org:act: 457537E4-AF3B-4884-84BE-C7AD79FF57D0 ( Figs 3A–E, I ) Type specimen. • Holotype : male, Kenya , Rift Valley , Kajaido North Dist. , Maasai Lodge 1,865 m , 1°23′4″S 36°49′51″E , 1 v 2015 , D.J.L. Agassiz , gen. slide no. CIS-7441, COI barcode CBNU260, in NHMUK . Diagnosis. This new species is similar in superficial and male genital characters to P. petiliella Park, 2020 , but it can be distinguished by the male genitalia: uncus slightly narrowed toward apex, whereas that of P. petiliella is more clavate distally; valva narrower at base, more narrowly elongated; and saccus much shorter, about 0.5 times shorter than that of P. petiliella ( Figs 3F–H ). Description. Male ( Figs 3A–C ). Wingspan 14.0 mm. Head : Vertex dark brown with orange-white erect scales laterally. Antenna thick, orange white, about 0.6 times shorter than the forewing length. Labial palpus slightly upturned; 2 nd segment thickened, covered with dark brown scales in basal 3/4, then gradually turning orange white toward apex on outer surface; 3 rd segment slightly curved upwardly, slender with sharply pointed apex, nearly same length as 2 nd segment, orange white entirely.

CIS-7341; G, ditto, close-up of uncus; H, aedeagus, holotype, slide no. CIS-7342; I, abdomen of P. oculiella , holotype. Thorax : Thorax and tegula dark brown, Forewing slightly broadened distally; ground color fuscous dark brown uniformly, with a distinct orange-white spot at apical end of discal cell; fainted blackish spots at basal 2/5 across wing medially; costa slightly arched at basal 1/6, nearly straight medially, then slightly oblique from beyond 5/6; apex more or less rounded; termen oblique with fringe concolorous with ground color. Hindwing broader than forewing, brownish gray. Abdomen : Dark brown, spinous zones forming a band on dorsal surface along posterior margin of each segment ( Fig. 3I ). Male genitalia ( Figs 3D, E ): Uncus elongated, slightly narrowed toward apex, with round apex. Gnathos strongly bent from before middle, with sharply pointed apex. Valva elongated, narrow at base, broadest at about basal 1/3; cucullus gradually narrowed toward apex, strongly upturned from 3/5; costa slightly expanded near base, then gently concave; ventral margin expanded in basal 1/3, then gently arched; apex rounded. Juxta broad at base, with nearly symmetrical caudal processes, longer than tegumen, pointed apically. Saccus rather short. Aedeagus slender, longer than valva, narrowed in basal 1/6; cornuti probably consisting of multiple broom-like setae but removed. Etymology. The species epithet is derived from the Latin, oculi (= eye) with Latin diminutive suffix, -ella , referring to the orange-white eye-like dot on the forewing. Distribution. Kenya .
