Tumicla mutinondo View in CoL sp. n.

( Figs 11–13 View Figures 11–19 , 29 View Figures 27–30 , 42, 43 View Figures 39–44 )

Type material. Holotype ( Figs 11 View Figures 11–19 , 29 View Figures 27–30 ): male, “ Zambia, 1460m, Mutinondo Wilderness Area, Mpika , Northern Province, 12°27'06'', E31°17'30'', 16–20.iii.2017, Actinic Light Trap, leg. Oram, D., Miles, W., Smith, L., ANHRT:2017.24”, unique number: ANHRT 00167892 , gen. slide No.: AV5993 ( ANHRT).

Paratypes. ZAMBIA: 2 females with the same data as the holotype, but MV Light Trap, unique numbers: ANHRT 00160061 , 00167891 , gen. slides Nos.: AV5957 and AV5994 ( ANHRT).

Remark. The females of T. mutinondo display two forms: the typical one ( Fig. 12 View Figures 11–19 ) is similar to the male holotype ( Fig. 11 View Figures 11–19 ) with a uniformly black distal half of the forewing with a gently curved postmedial line, while the other ( Fig. 13 View Figures 11–19 ) has an orange forewing apex and terminal area with a strongly undulating postmedial line. Despite the conspicuous external differences, these two forms have identical genitalia ( Figs 42, 43 View Figures 39–44 ).

Diagnosis. The forewing length is 10 mm in the male holotype and 12.5– 13 mm in females. The new species ( Figs 11–13 View Figures 11–19 ) is similar externally to T. admiranda Volynkin & László, 2019 ( Figs 14, 15 View Figures 11–19 ) but distinguished by the blackish antennae, head and medial section of the thorax (orange in T. admiranda ), the blackish abdomen (dark brown in T. admiranda ) and the blackish basal and distal areas of the forewing and distal area of the hindwing (dark brown in T. admiranda ). Additionally, the blackish basal area of the forewing of T. mutinondo is much smaller than in T. admiranda , more rounded and present only in the dorsal half of the subbasal area fusing with a blackish costal stripe. In T. admiranda the narrow basal area is orange, followed by an extensive dark brownish, distally evenly rounded basal area occupying the whole subbasal and antemedial areas and reaching the anal margin. The male genitalia of T. mutinondo ( Figs 29 View Figures 27–30 ) are reminiscent of T. smithi ( Fig. 30 View Figures 27–30 ) and T. admiranda ( Fig. 31 View Figures 31–33 ). The male genital capsule of the new species is most similar to that of T. smithi but differs in its shorter valva with a narrower apical process and a wider and more heavily setose sacculus. Additionally, the vinculum of the new species is considerably longer and wider than in T. smithi . Compared to T. admiranda , the male genital capsule of T. mutinondo has a conspicuously narrower and more or less straight tegumen, which is strongly curved ventrally in its congener. The apical process of the valva of T. mutinondo is wider and curved dorsally, whereas it is narrower and directed distally in T. admiranda . Additionally, in T. mutinondo , the uncus is considerably narrower and less curved and the sacculus is much wider and more heavily setose than in T. admiranda . The aedeagus of the new species is somewhat shorter and thicker than in T. smithi but considerably longer and thicker than in T. admiranda . The vesica of T. mutinondo is thicker and longer than in T. smithi , bearing a considerably longer and wider cluster of larger spine-like cornuti. Compared to T. admiranda , the vesica of the new species is markedly longer and thicker bearing a more extensive cluster of thicker cornuti which cover only the distal two thirds of the main vesica chamber (in T. admiranda the cornuti field covers the whole length of the chamber). The female genitalia of T. mutinondo ( Figs 42, 43 View Figures 39–44 ) are reminiscent of T. smithi ( Fig. 44 View Figures 39–44 ) but differ by their shorter apophyses anteriores, the markedly shorter ductus bursae and the weakly sclerotized left margin of the posterior section of the corpus bursae (whereas in T. smithi the posterior section of the corpus bursae is evenly sclerotized). The female genitalia of T. mutinondo can easily be distinguished from those of T. admiranda ( Fig. 46 View Figures 45–47 ) by the absence of both an inner pocket-like protrusion of the 8 th sternite and postvaginal plate, the considerably longer and narrower ductus bursae and the structure of the posterior section of the corpus bursae (longer and evenly sclerotized except for its left margin in T. mutinondo , and shorter with a short and narrow sclerotized area latero-posteriorly only in T. admiranda ). Additionally, the anterior section of the corpus bursae of T. mutinondo is more membranous and without a signum bursae, whereas in T. admiranda it is membranous, with a signum bursae that is weakly scobinated.

Distribution. The species is only known from its type series which was collected in the pristine Miombo woodlands of Mutinondo Wilderness Area in the Muchinga Mountains, northeast Zambia.

Etymology. The species is named after its type locality.
