Description

Based on the evidence provided above, Compsoneuria can no longer be included in the Heptageniinae and is placed in Ecdyonurinae, with the name Compsoneuriini accompanying its type genus to Ecdyonurinae. The potential relationships of Compsoneuria to other Ecdyonurinae are discussed below. The phylogenetic concept of the Heptageniinae clade defined by larval characters that Wang and McCafferty (2004) named Compsoneuriini remains the same; however, this concept is now relevant only to the genus Trichogenia. Given the constraints of a strict phylogenetic classification, we must establish a new tribe, Trichogeniini Webb & McCafferty N. TRIB., allowing each of the additional eight Heptageniinae genera to retain their generic status. Braasch and Soldán (1986 a) noted that adults of Compsoneuriella thienemanni Ulmer, 1939, the type species of Compsoneuriella Ulmer, were congeneric with C. spectabilis adults and synonymized Compsoneuriella with Compsoneuria. Wang and McCafferty (2004) did not recognize this synonymy because they believed Compsoneuria to be a member of the Heptageniinae, and placed Compsoneuriella as a junior synonym of Thalerosphyrus instead, based on the shared possession of long, pointed supracoxal sclerites in the larvae. Examination of larvae and males of several species of Thalerosphyrus and Compsoneuriella indicates, however, that the two are distinct. The penes of Compsoneuriella are slightly expanded laterally, are only partially fused medially, have distinct dorsal sclerites both apically and laterally, and have ventral and dorsolateral spines. The penes of Thalerosphyrus are not expanded laterally, are fused medially for most of their length, do not have ventral or dorsolateral spines (small dorsolateral spines may be present in some species), and do not have as well-developed apical sclerites. Additionally, the forewings of the two genera differ in that those of Compsoneuriella tend to have a reduced number of crossveins and a slightly sigmoidal bend in the costa and subcosta, whereas those of Thalerosphyrus have numerous crossveins and a straight costa and subcosta. The legs of Compsoneuriella have numerous black spots that are not present in Thalerosphyrus. The larvae of Thalerosphyrus and Compsoneuriella also differ in many characters. Thalerosphyrus larvae, for example, have well developed posterolateral spines on the abdomen, simple setae on the inner surface of the hindtibiae, slight posterolateral extensions of pronotum, distinct thickening of the anterior margin of the head capsule, do not possess any black spotting on the head capsule or femora, and the glossae are subquadrate and laterally expanded. Compsoneuriella larvae, on the other hand, generally have shorter posterolateral spines on the abdominal segments, have fimbriate setae on the inner surface of the hindtibiae, generally lack posterolateral expansions on the pronotum, do not have the anterior margin of the head capsule thickened, usually have conspicuous black spots on the head capsule and/or femora, and the glossae are narrow and pointed apically. For these reasons, we no longer recognize any synonymy of Compsoneuriella with Thalerosphyrus and because all of the adult characters of Compsoneuriella are present in Compsoneuria, we recognize the previous synonymy of Compsoneuriella with Compsoneuria. All African species transferred to Thalerosphyrus by McCafferty (2003) are recombined with Compsoneuria. The phylogenetic position of Compsoneuria (and Compsoneuriini) within the Ecdyonurinae is unclear. The possession of ventral spines on the penes, the general shape and the sclerotization of the penes, and the possession of black spotting on the head capsule indicate Compsoneuria may be related to members of the tribe Leucrocutini Wang & McCafferty. However, unlike other members of the Leucrocutini, the apical setae on the ventral side of the galealaciniae are simple rather than fimbriate, and the distal dentisetae on the maxillae are branched rather than simple, indicating a closer relationship to the Notacanthurini Wang & McCafferty and Atopopini Wang & McCafferty. The long supracoxal sclerites of the larvae are similar to those found in most Thalerosphyrus (a member of Atopopini) but we believe this to be a case of convergence as Compsoneuria lacks apomorphies of the Atopopini such as a thickened anterior margin of the larval head capsule. In most males of Atopopini, the first foretarsal segment is greater than 0.5X the length of the second segment; in Compsoneuria, the length varies from 0.3-1.0X the length of the second segment. We presently consider Compsoneuria to include the following species: Compsoneuria bequaerti (Navás)AFROTROPICAL
