Volynkin, Anton V. & László, Gyula M., 2020, Six new species of the genus Tumicla Wallengren, 1863 (Lepidoptera: Erebidae: Arctiinae: Lithosiini), Ecologica Montenegrina 38, pp. 36-50 : 44-48

Tumicla turlini sp. n.

( Figs 18, 19 , 41 )

Type material. Holotype ( Figs 18 , 41 ): female, “ Rwanda, Butaré, 3-VI-[19]74, B. Turlin ”, gen. slide No.: ZSM Arct. 2019-215 (prepared by Volynkin) ( ZSM).

Paratype: RWANDA: female, Gashora Bugesera , savane arbustive [shrubby savanna], 24.xi.[19]74, 1400m, gen. slide No.: ZSM Arct. 2019-533 (prepared by Volynkin) ( ZSM).

Diagnosis. The forewing length is 13.5–14.5 mm in the females. The female of T. turlini ( Figs 18, 19 ) is externally most similar to T. smithi ( Fig. 17 ) but differs in the absence of the discal spot and the black longitudinal basal dash. The female genitalia of the new species ( Fig. 41 ) are reminiscent of those of T. smithi ( Fig. 44 ) and T. mutinondo ( Figs 42, 43 ), but can easily be distinguished by their considerably shorter ductus bursae, the conspicuously wider posterior section and smaller anterior section of the corpus bursae as well as the much shorter appendix bursae. Additionally, compared to T. smithi , the posterior section of the corpus bursae of T. turlini is more widely protruding in its left margin and evenly sclerotized while in T. mutinondo the left margin is membranous.

The male is unknown.

Distribution. The new species is known only from Rwanda, the type specimens having been collected in a savannah habitat.

Etymology. The species is named after the renowned French lepidopterist and collector of its type specimens, Dr Bernard Turlin.
