Tuthillia, a new Neotropical psyllid genus (Homoptera: Psylloidea)
Systematic Entomology 11 (1), 53-60
Abstract: Tuthillia gen.n. (Homoptera: Psylloidea) is erected for four Neotropical species: canabina sp.n. (the type-species from Belize and Panama), cognata sp.n. (Brazil), latipennis sp.n. (Panama) and iuncta sp.n. (Brazil). It is suggested that Tuthillia forms a monophyletic group with the ciriacremine genera Ciriacremum, Kleiniella and Palmapenna. However, only iuncta possesses an R-M cross vein in the forewing, a character which has been used to define the ciriacremines in the past. It seems, therefore, that this character is unstable and alternative synapomorphies are discussed. The genital morphology of Tuthillia is similar to that found in both Ciriacreminae and Diaphorininae (Aphalaridae). It is speculated that these subfamilies represent previously unrecognized sister groups defined using the genital characters as synapomorphies.
