Etymology
. Imana is the Creator deity in the traditional Banyarwanda religion in
Rwanda
.
Diagnosis
. The closest relative of the new species is
Siccia microsticta
Hampson, 1914
(
Figs 5–8
), from which
S. imana
sp. nov.
(
Figs 1–4
) can be easily distinguished by its much larger size (forewing length is
11–13.5 mm
in the new species and
7–9.5 mm
in
S. microsticta
), and well-developed antemedial, medial and subterminal transverse lines (while in
S. microsticta
only postmedial line is more or less visible, but usually diffuse). Externally,
S. imana
most resembles
Siccia atriguttata
Hampson, 1909
(
Figs 9
,
12
), but differs by its larger size (forewing length is
10–11 mm
in
S. atriguttata
), shorter pectination of male antennae, more diffuse pattern elements, solid medial line (while that is interrupted medially in
S. atriguttata
), and the male genitalia structure. The male genitalia of
S. imana
(
Fig. 10
) differs from that of
S. microsticta
(
Fig. 11
) by its uncus being slightly broader medially, broader costa with a short bulge basally (that is absent in
S. microsticta
), narrower and trigonal distal lobe of the dorsal part of valva (while that is much broader and more or less rounded in
S. microsticta
), broader spinulose tip of the distal saccular process, broader aedeagus, and absence of a subbasal dorsal cluster of short spinules in vesica. The female genitalia of
S. imana
(
Figs 13, 14
) differs from that of
S. microsticta
(
Fig. 15
) by its larger papillae anales, heavily sclerotized and rugose antevaginal lateral lobes, which are directed laterally (while those are more weakly sclerotized, densely setose, C-like curved and directed more or less posteriorly in
S. microsticta
), narrower and membranous ductus bursae (that is broader and heavily sclerotized in
S. microsticta
), rectangular posterior plate of corpus bursae situated at connection with ductus bursae (in
S. microsticta
, that is elliptical with V-like posterior groove and situated more posteriorly, in the membranous anterior section of ductus bursae), and solid lateral band of spinules in corpus bursae (that is interrupted and consists of a long band and a separated bunch of spinules in
S. microsticta
).
