Diagnosis
. The forewing length is
11–12 mm
in males and
12–14 mm
in females. The new species (
Figs 3, 4
) is externally similar to
M. metallica
(
Figs 1, 2
) but is distinguished by the smaller size, the more intense metallic green suffusion on the forewing, and the paler brown dash outward from the reniform stigma. Compared to
M. metallica
(
Fig. 21
), the male genital capsule of
M. leichina
sp. n.
(
Fig. 22
) has a somewhat narrower juxta with a deeper medial depression and a larger swollen ventral process. The valva of the new species is basally broader than in
M. metallica
, more down curved distally, and has a broader apex and an extremely short ventral subapical protrusion. The harpe of the new species has a broader base than in the congener and is only slightly apically dilated whereas in
M. metallica
, it is arrowhead-like dilated subapically and bears a short triangular dorsal protrusion. The sacculus of
M. leichina
sp. n.
has a slightly larger distal process and a prominent, lobe-like clavus whereas the clavus of
M. metallica
is very short but broad and only slightly protrudes from the sacculus surface. The phallus of the new species is somewhat shorter than in the congener (in proportion to the length of the tegumen-uncus complex), slightly more down curved, bears a somewhat larger lateral thorn-like carinal process and lacks a dorsal dentate carinal plate. The vesicae of the two species are similar but that of
M. leichina
sp. n.
is somewhat basally broader than in the congener and has a smaller distal diverticulum. In the female genitalia of the new species (
Fig. 31
), the apophyses are apically narrower than in
M. metallica
(
Fig. 30
), and the apophysis posterioris is somewhat longer (in proportion to the length of the apophysis anterioris). The antrum of the new species is narrower than in
M. metallica
, has markedly longer and broader ventral postero-lateral subostial lobes and a rugose ventral surface between them (whereas it is smooth in the congener). The ductus bursae of
M. leichina
sp. n.
is somewhat longer than in
M. metallica
and has a broader and anteriorly straight lateral sclerotised plate whereas it is anteriorly curved and reaching the base of the appendix bursae in
M. metallica
. The corpus bursae of
M. leichina
sp. n.
is conspicuously shorter and broader than in
M. metallica
and bears only one small signum whereas that of the congener bears four larger signa. Additionally, the appendix bursae of the new species is somewhat narrower than in
M. metallica
and has a more constricted basal section.
Distribution
. The new species is known only from its
type
locality in north-western
Yunnan Province
of
China
.
Etymology.
‘Leichina’ is a Latin transliteration of the Greek word ‘λειχήνα’ meaning ‘lichen’. The specific epithet refers to the diffuse shiny green spots and suffusion on the forewing reminiscent of certain groups of lichens. The gender is feminine.
