Walker, 1869

Remarks:
Desutter-Grandcolas (1992: 95)
defined the
Luzarini
based on the morphology of the male genitalia, stating that ‘chez les
Luzarinae
[
sic
], toute la partie médiane de l’épiphalle est régressée, notamment les lophi médians; d’autre part, les “bras épiphalliques” ainsi formés acquièrent une structure complex, avec généralement une ou deux zones de rupture ou d’articulation et des épines latérales’. The retrograde median region of the epiphallus is unique amongst
Luzarini
, and is likely to be apomorphic. The complex ‘bras épiphalliques’, or ‘epiphallic arms’, and their lateral lobes are highly variable: their morphology and spatial associations with the epiphallic parameres have proved very useful at lower taxonomic levels (e.g.
Desutter-Grandcolas, 1992
,
1993
;
Desutter-Grandcolas & Otte, 1997
).
