Dolocucullia Poole
Dolocucullia is one of a group of three
genera placed in the Cuculliinae without spines in the male vesica. The
spines are replaced by sclerotized, often dentate, nodules. The other
two genera are Opsigalea and Emariannia. These three
genera are most diverse in Mexico and Central America, although species
of Opsigalea reach as far south as northern Argentina and one
species of Dolocucullia is known from the mountains of Peru.
This group of genera is probably an offshoot of the line that gave rise
to Cucullia because they share with Cucullia the same
basic structure of the male valve, the same general vesica shape despite
the absence of spines, and the same external tympanic structure. There
are two major differences, however, between the female genitalia of Dolocucullia
and Cucullia. First, the ductus seminalis arises from the caudal,
not cephalad, end of the corpus bursae. Second, a sclerite is present
between the two ovipositor lobes in Dolocucullia. This sclerite
is found elsewhere in the trifid noctuids, but not in Cucullia. The larvae and their foodplants are unknown for all known species
of Dolocucullia. |
