Genus
Manulea
Wallengren, 1863
Manulea
Wallengren, 1863
,
Wiener entomologische Monatschrift
, 7: 145, 146.
Type
species:
Lithosia gilveola
Ochsenheimer, 1810
(a junior synonym of
Phalaena palliatella
Scopoli, 1763
), by subsequent designation of
Moore (1878)
.
Diagnosis.
Imago
. Forewings narrow with nearly straight costal margin and a pale line along it; externally resembles many other groups of
Eilema
sensu lato
. In some species, androconial scales are present on the costal margin of the forewing underside.
Male genitalia.
Uncus cylindrical, moderate in width, with a small hooked end; valvae oval or contracted apically, sacculus process ending with and inwardly curved hook, not fused with the valve ending (cucullus); clasper absent; juxta with poorly developed lateral apical processes; vinculum trapezoidal, membranous with a horizontal base, with sharply sclerotised edges; aedeagus thick, globular and large with an apical sclerotised fascia in the form of a spine turned backwards and two cornuti, spike like, of different size.
Female genitalia.
In the female genitalia, the main characteristic is the large appendix bursae in comparison to the corpus bursae.
Remarks.
Manulea
was treated as different from
Eilema
by Edwards (1996) but was based on Australian species that are significantly different from the
type
species of both genera.
The genus was characterized and compared with
Eilema
in detail by
Dubatolov & Zolotuhin (2011)
. No autapomorphies can be recognized, but in the male genitalia, the combination of the following features is characteristic for the genus: (1) the vinculum is trapezoidal and membranous, with thin and weakly sclerotised arms. (2) the valvae has a long and wide dorsal part with thin costa lacking processes; (3) the sacculus is relatively narrow and has an elongate saccular process, well separated from the dorsal part of the valve (cucullus), (4) the aedeagus vesica broad and bearing few robust cornuti. A similar structure of the vinculum is also known in several other genera, namely the Eurasian
Eilema
,
Tarika
,
Collita
, and the African
Lepidilema
,
Dimorphilema
,
Syntemnilema
and
Lophilema
, but all these genera differ from each other by their valvae structures.
Molecular data.
Within the
Eilema
/
Manulea
group, the genus
Manulea
constitutes a clade with moderate Bayesian support (PP=0.61), with
Manulea complana
and
Manulea pseudocomplana
forming an internal wellsupported clade (PP=0.93). Genetic TN distances between
Manulea
species
are, in all cases, below 5% (1.21– 4.99%) while showing higher distances with
Eilema caniola
(5.43–5.98%). RESL Cluster Sequences Analysis (Ratnasingham & Herbert, 2013) returned 5 clusters corresponding to the four existing
Manulea
species
plus an additional cluster including the samples belonging to
Manulea iberica
. Most of the COI sequences were assigned with high confidence (>98% match) to a pre-existing BIN for the corresponding species. Only the clusters coinciding with the samples of
Manulea costalis
(Zeller, 1847)
and
Manulea iberica
(
Mentzer, 1980
)
, with no previously published records, did not match any existing BINs. It is also worth to mention that Maximum Likelihood tests performed independently for each genetic marker (data not shown) returned highly compatible tree topologies between markers and compared with the Bayesian Inference tree.
The analysis of published sequences attributed to
Manulea bicolor
(Grote, 1864)
,
Manulea dorsalis
(Walker, 1866)
,
Manulea replana
(Lewin, 1805)
,
Manulea ussurica
(Daniel, 1954)
,
Manulea japonica
(Leech,1889)
and
Manulea
sp.
shows that they are all more closely related to other genera (
Setema
,
Katha
or others) than to
Manulea
, with no specimens falling within the
Manulea
clade (
Fig. 120
). This can be interpreted as a clear example of the current lack of consistency of this genus in the sense that the
type
species is not representative of all the species that have been and continue to be placed in it. There is no doubt that the assemblage of species referred to
Manulea
needs a major revision.
