Remarks. Dannfeltia nana, thought synonym of Phaneroptera sparsa Stål, 1857, was recently reinstated as different genus on the basis of the stridulatory file shape and other characters (Massa 2021a). An overlooked character that allows to separate Dannfeltia from Phaneroptera is the ratio between the length of hind wings and tegmina; in Phaneroptera it is 1.4-1.5, while in Dannfeltia is 1.2-1.3, the hind wings exceeding not so much tegmina as in Phaneroptera . D. nana is presently known from Democratic Republic of Congo (holotype), Mozambique (present specimens), Gabon, Central African Republic, and Ivory Coast.
Description of the female. Among specimens collected in Mozambique also 3 females of this species were collected, whose habitus was previously unknown. Characters are the same of the male (see the re-description in Massa 2021a), with the exception of the subgenital plate, which is short, and triangularly pointed. The ovipositor is more upcurved than in Phaneroptera .
Measurements of the females (in mm). Body length: 13.0-13.9; length of pronotum: 3.2-3.4; height of pronotum: 2.4-2.5; length of hind femora: 13.7-14.3; length of tegmina: 18.7-18.8; width of tegmina: 3.9-4.0; length of ovipositor: 3.9-4.0.
