(1) Elongated antennomeres, apical almost 4 times longer than wide from the original description (Silvestri 1928) (2) “Legs relatively long” from the original description (Silvestri 1928)
(3) “Labial palpus conical, much longer than wide, …” from the original description (Muegge 1992)
(4) No data in the original description (Pagés 1952)
(5) Uncertain ratio; it has been estimated using length of their telescoping antennae
(6) Old fashioned description without such sensilla observation
(7) Didn’t mentioned in the references
