28224B470F09706EFF0EFF16FEC7EB87.taxon	diagnosis	Diagnosis. The closest relative of the new species is M. (M.) jordani Kiriakoff, 1957 described from Mount Moco in western Angola. However, the two species are readily distinguished by the following characters: Metarctia (Metarhodia) lunda sp. n. is larger in size (forewing length of M. (M.) jordani is 12 mm) and it lacks the conspicuous pinkish ochreous spots at the anal vein, in the cell and between M 1 and M 2 veins, displaying dark grey-brown patches instead; furthermore, the similarly pale cream rami are ca. 25 % shorter in the new species. In the male genitalia, M. (M.) lunda sp. n. has a shorter, dorsoventrally more dilated uncus, a somewhat longer costal process and cucullus (medial process), a considerably longer saccular process of the valva and a larger juxta with markedly wider laterodistal lobes compared to those of M. (M.) jordani.	en	László, Gyula M., Volynkin, Anton V.

The shared male genitalia feature of the subgenus is the trilobate valva displaying a narrow, digitiform, apically setose costal process, an elongate, narrow cucullus as a medial process of the valva and a well-defined saccular lobe or process. As a result of this study, a well-defined species group comprising M. (M.) jordani, M. (M.) lunda sp. n., M. (M.) sangha sp. n. and M. (M.) bemba sp. n. can be delimited with species possessing cream-coloured antennae and considerably longer cuculli as well as narrower, more elongate saccular processes than is observed in the other members of the subgenus (cf. Przybyłowicz 2009). The species of this complex show an allopatric distribution pattern in central- and southern-central Africa and the relatively limited morphological divergence of these taxa may suggest a recent radiation. Additional research is required to specify the exact distribution range of these species and discoveries of further species of this complex cannot be ruled out. Acknowledgements In the Republic of Congo, our cooperative partner, the Wildlife Conservation Society (WCS) Congo and their employees authorised research in NNNP and provided diverse administrative and technical support during the expedition. We express our gratitude to the following WCS staff: Morgane Cournarie (Program coordinator), Vittoria Estienne (Director of Research and Biomonitoring), Ben Evans (Park Director), Richard Malonga (Director), Onesi Samba (Research Assistant), Yako Valentin (Administrative Manager), Tatiana Thomas (Camp Manager, Mondika). The authors are also grateful to Joseph Goma-Tchimbakala (General Director of IRSEN, Institut National de Recherche en Sciences Exactes et Naturelles), for issuing the necessary research and export permits and Jean Bosco Nganongo (Directeur de la DFAP Direction de la Faune et des aires protégées), for issuing CITES permits. We further thank Victor Mamonekene (Hydrobiologist, Ichthyologist, IRSEN and Marien Ngouabi University) for his valuable assistance. Last but not least, we are indebted to Violette Dérozier who very ably organised ANHRT’s series of expeditions conducted in NNNP. In Zambia, Rhoda Kachali (Department of National Parks and Wildlife – ZAWA, Lusaka), Claire Mateke and Martha Imakando (Livingstone Museum, Livingstone) are thanked for the diverse administrative and technical assistance provided during fieldwork as well as for issuing the research and export permits. Alberto Zilli and Geoff Martin (NHMUK) are thanked for kindly facilitating access to the Syntomini type and accession materials under their care.
