Autapomorphies of Madecocercus. (1) Maxillary palp is lost. Non-unique apomorphy, the same in some Ephemerella/fg1 (see Index of characters [1.1.41]). (2) Marginal processes of tergalii IV-VI are non-branched, thus only tergalius III retains branched processes [see Caenotergaliae (1) and Caenoptera (4)]. On all tergalii III-VI on proximal-anal margin processes are substituted by setae of similar size (Kluge 2004: Fig.85:C–D). (3) Larval body has peculiar shape: flattened and widened, femora strongly widened, with regular rows of long setae on outer and inner margins; dorsal surface of body and legs is warty, on fore femur warts form a transverse row (which originally was confused with a setal row in Pantricorythi). Plesiomorphies of Madecocercus. Prosternum is wide and rectangular; metanotum without transverse crest, flat, with scutellum distinctly projected posteriorly (Malzacher 1995: Fig.1c,d) (the same in Brachycercus/f1=g3, unlike Caenis/f4=g2). Gonostylus with a longitudinal groove [see Caenoptera (5)]. |
Size. Larval body length 5–6 mm (see Caenoptera).
Distribution. Madagascar.
