Sixty new dragonfly and damselfly species from Africa (Odonata) Author Dijkstra, Klaas-Douwe B. Author Kipping, Jens Author Mézière, Nicolas text Odonatologica 2015 44 4 447 678 journal article 10.5281/zenodo.35388 Notogomphus bosumbuli Dijkstra sp. nov. – Congo Longleg ( Type Photo 31 , Photos 40 , 45 , Figs 18 , 19 ) Taxonomy The genus Notogomphus Selys, 1858 is typically associated with highlands and this is the first species to be found in the central Congo Basin ( Map 8 ). Although not all potentially close relatives are available for genetic comparison, it is distinct, also in morphology, and has already been treated as such by Dijkstra & Clausnitzer (2014) . Material studied Holotype ♂ . RMNH.INS.502416 , Congo-Kinshasa , Province Orientale , Lower Lomami, Yendega, Bosega and Bogunu streams in forest west of Djabir and Yaengo , shallow streams and springs with sand, gravel and leaf litter in forest ( Photo 45 ), 380 m a.s.l.

Further material. 3 ♂ ( RMNH.INS.502259 ), 1 ♀ ( RMNH.INS.502411 ), as holotype, RMNH . Map 8. Distribution of N. bosumbuli sp. nov. , N. cobyae sp. nov. , N. gorilla sp. nov. , N. intermedius sp. nov. , N. kimpavita sp. nov. and all other species of Notogomphus . Figure 18. Head in rostral (left) and thorax in dorsal (middle) and lateral view (right) of dark Notogomphus species of central Africa; N. bosumbuli sp. nov. is not shown but the head is like N. leroyi and thorax like N. gorilla sp. nov. Genetics Two unique haplotypes (n = 3) nearest to female from Uganda identified as N. lujai (Schouteden, 1934) , but N. leroyi (Schouteden, 1934) was not sampled. Male morphological diagnosis Recalls N. leroyi by its (a) largely black lower frons, clypeus and labrum, the latter with a pair of large basal pale spots (like N. leroyi in Fig. 18 ); (b)black occiput; (c) broad and complete black interpleural and metapleural stripes on the thorax as well as well-defined pale postdorsal and ante-humeral stripes separated from each other and the pale area of the middorsal carina (like N.gorilla in Fig. 18 ); (d) the smooth curve of the anterior border of the posterior hamule; (e) the somewhat convergent cerci with a ventral tooth that is directed straight downwards and thus not visible in dorsal view; and (f) the strongly diverging branches of epiproct ( Fig. 19 ). However, it is (1) larger on average, Hw 34.0–35.0 mm (n = 4) rather than 31.0–34.0 mm (n = 4); (2) the abdomen is parallel-sided, with S 7–9 scarcely expanded and S 8 longer than high or wide; (3) S 8–9 are black marked laterally rather contrastingly with yellow, rather than uniformly dark rufous; and (4) the cerci are of rather even width throughout in dorsal view, rather than expanded distally ( Fig. 19 ). Figure 19. Male appendages in dorsal (left) and lateral view (right) of selection of Notogomphus species. Etymology Name is derived from a local word “bosumbulisumbuli” meaning dragonfly (noun in apposition). Range and ecology Only known from sandy rainforest streamlets about 30 km south of Isangi but also seen in the Yoko Forest near Kisangani, 130 km to the east; both sites are at only around 400 m a.s.l. in the central Congo Basin.
