Notogomphus intermedius Dijkstra

sp. nov.

Notogomphus intermedius Dijkstra   ZBK   sp. nov. – Katanga Longleg (Type Photo 34, Photos 47, 64, Figs 19, 20)


Fraser (1955) illustrated a female from Upemba National Park in Katanga   as N. lujai   , but identified (in lit.) a similar but teneral male from nearby Kalule (near Lubudi on the southern edge of the park) as N. meruensis (Sjöstedt, 1909)   . SjÖstedt (1909) described the latter from a teneral and damaged male from Mt Meru, while describing N. kilimandjaricus (Sjöstedt, 1909)   from a mature female from neighbouring Mt Kilimanjaro. The N.meruensis   holotype is accompanied in NHRS by a teneral female labelled » Cotypus «, collected at the same site two days earlier. This female and the N. kilimandjaricus   holotype agree in head armature and markings. The N.meruensis   holotype’s markings are largely indiscernible, but similar on face, mesepisternum and S 9–10. The appendages are lost, with the exception of the base of the cerci and their ventral teeth, whose shape agrees with males identified as N. kilimandjaricus   from northern Tanzania and southern Kenya, as does its secondary genitalia. Sjöstedt’s two species thus appear identical and the obscurity of N. meruensis   warrants selection of N.kilimandjaricus   as the taxon’s valid name [new synonymy]. The facial patterns of both Fraser’s Katanga   specimens agree and are unlike that of any other Notogomphus   species. Recent material of both sexes matched this pair and confirmed that they represent a morphologically and genetically distinct species, which Dijkstra & Clausnitzer (2014) have already treated as such.

Material studied

Holotype ♂. RMNH.INS. 505650: Congo-Kinshasa, Katanga   , Kundelungu National Park, Masansa , small river with some gallery forest and falls in miombo woodland, 1440 –1480 m a.s.l. (10.532 ° S 27.978 ° E), 22 -xi- 2011, leg. K.-D.B. Dijkstra, RMNH View Materials GoogleMaps   .

Further material. CONGO-KINSHASA ( Katanga   ): 1 ♂, as holotype, RMNH GoogleMaps   . 1 ♂ ( RMNH.INS. 505521), Upemba National Park, Lusinga valley 3 km E of park headquarters , stream with patches of gallery and swamp forest, open swamp and arable fields, 1570 – 1590 m a.s.l. (8.93 ° S 27.23 ° E), 13 -xi- 2011, leg. K.-D.B. Dijkstra, RMNH View Materials GoogleMaps   . 1 ♀ ( RMNH.INS. 505581), Upemba National Park, broken bridge on Lusinga , river with gallery forest in miombo woodland, 1475 m a.s.l. (8.8998 ° S 27.2827 ° E), 16 -xi- 2011, leg. K.- D.B. Dijkstra, RMNH View Materials GoogleMaps   . 1 ♂, Kalule , 820–840 m a.s.l., i- 1934, leg. Ch. Seydel, MRAC   . 1 ♀, Upemba National Park, Mubale River , 01– 20 -v- 1947, leg. G.F. de Witte, MRAC   .


Two unique haplotypes (n = 3) well-separated from other Notogomphus   species including N. zernyi   (St. Quentin, 1942), but most of the numerous paler species were not sampled.

Male morphological diagnosis

Recalls N. zernyi   and other pale Notogomphus   by (a) small size, Hw 28.5– 29.5 mm (n = 4); and (b) the largely pale yellow face, thorax sides, Pt, hind Type Photo 34. Holotype of Notogomphus intermedius   sp. nov., RMNH.

femora and complete dorsal and lateral stripes on S 1–7. However, (1) while labrum and postclypeus are largely pale, the lower borders of antefrons, anteclypeus and labrum are darkened, a distinctive pattern within the genus ( Fig. 20); (2) the tibiae are all black, without yellow streaks; (3) the costa is dark, rather than yellow; (4) the dorsum of S 8–10 is black without a pale yellow stripe and the sides of S 8–9 are dark yellow; and (5) the cerci are rather simple in shape with ventral teeth directed outwards and visible in dorsal view ( Fig. 19).


Intermediate in characters between the pale highland and dark forest species, but not particularly distinctive in other features (masculine adjective).

Range and ecology

Small rivers in miombo woodland flowing off the Kibara, Manika and Kundelungu plateaus in Katanga   ( Photo 64), roughly between 800 and 1 600 m a.s.l ( Map 8).
