Pseudopannota sp. U

( Fig. 15 )

?= Pseudocloeon camerunense: Kimmins 1960: 344 (non Ulmer 1920)

Material examined. UGANDA, Jinja District: Bujagali Falls at river Nile , 7.VII.2007, coll. N. Kluge: incomplete exuviae of 1 female ultimolarva , 1 male imago; Jinja, FIRRI, 6– 10.VII, coll. N. Kluge: 2 male imagoes.

Morphological notes. Larva. Similar to P. pannota sp. n., differs as the following. Proximal subsegment of first segment of maxillary palp has cuticle entirely membranous, so that on shed exuviae it does not keeps its form, being inverted and entirely dipped into maxilla ( Fig. 15 ). Distal subsegment of first segment is not widened apically, narrower than proximal part of primary second segment ( Fig. 15 ). Femora, tibia and tarsi shorter and thicker, than in P. pannota sp. n.; hind femur without orange-brown markings on cuticle of posterior side (but all legs with orange-brown marking on tibial base). Posterior margin of tergum I with small denticles. Abdominal segments VII–X, tergalii and caudalii missing.

Male imago (presumably associated with larva). Turbinate eyes gray or ocher. Thorax ocher with light brown, lighter than in P. pannota . Abdominal tergum IV as light as previous ones; brownish coloration beginning from tergum V. Genitals as in P. pannota sp. n. (as in Figs 2 , 55 ).

Dimension. Fore wing length of male imago 5.5. mm.

Discussion. Kimmins (1960) reported this species from Jinja and Entebbe in Uganda under the name “ Pseudocloeon kamerunense ”, but noted that the “ Uganda examples are rather larger” and that Ulmer “shows a much more definite point on the inner angle of the forceps-base ...”. Imagoes collected by me in Jinja and Bujagali Falls agree with these notes and possibly belong to the same species. Association of these imagoes with exuviae of a single larva from the same locality is poorly presumable.
