Diagnosis
. The forewing length is
6.5 mm
in males and 7.0 mm in females.
Siccia intermedia
is externally very similar to
S. margopuncta patterna
and
S. myraina
, and the reliable identification requires the examination of the genitalia structures. Compared to another similar species, the allopatric
S. trichota
, the new species has a smaller discal spot on the forewing. The male genital capsule of
S. intermedia
is most similar to
S. myraina
due to the presence of the dense cluster of spines on the dorsal margin of the costa proximally as well as the cluster of a few robust spines on the anellus, and the medially constricted uncus. However, unlike
S. myraina
, the aforementioned cluster of spines on the dorsal margin of the costa of the new species is shorter and narrower, the valva is broader and has two large and one tiny process distally (more similar to
S. trichota
), and the anellus bears fewer and thinner spines. Compared to
S. myraina
, the distal section of the valva of
S. intermedia
has a proximally thinner apical process of the cucullus, and a reduced distal process bearing a considerably smaller dorsal and a larger ventral process. The vesica configuration of the new species is reminiscent of
S. myraina
and
S. trichota
but distinguished by the longer medial diverticulum and the narrower distal multilobate diverticulum. In the female genitalia,
S. intermedia
is similar to
S. trichota
but differs in the shorter apophyses, the shorter but broader spinulose lateral subostial lobes, the broader lateral sclerotised plates of the 7
th
sternite, and the shorter corpus bursae having a considerably longer posterior signum and smaller medial and anterior signa.
Distribution
. The new species is currently known from
Republic of the Congo
and
Democratic Republic of the Congo
.
Etymology
. The specific epithet refers to the new species’ valva structure, which combines features of
S. myraina
and
S. trichota
.
