Diagnosis
. The forewing length is 9.5–10.5 mm in males and 9.5 mm in the female.
Miltochrista velona
is externally very similar to the Indian
M. neoseriata
and
M. paraseriata
, and the sympatric
M. pachia
, and reliable identification requires the examination of the genitalia structures. The male genitalia of the new species are most similar to the externally dissimilar
Miltochrista parallelinaformis
Bucsek, 2020
(
Figs 12
,
31
) recently described from
Laos
(
Bucsek 2020
) but distinguished by the broader valva with a markedly larger medial dorsal protrusion of the costa (the dorsal margin is only slightly medially convex in the congener), and the longer distal costal process bearing a markedly longer needle-like tip. The male genital capsule of
M. velona
is also reminiscent of the Andaman
Miltochrista phantasma
(Hampson, 1907)
(
Figs 15, 16
) and the Sundanian
Miltochrista acutiseriata
(
Holloway, 2001
)
(
Figs 17–20
) but distinguished from the former species (
Fig. 32
) by the laterally flattened and proximally slender uncus (it is dorso-ventrally flattened and strongly proximally dilated in
M. phantasma
), the markedly larger medial dorsal protrusion of the costa (the dorsal margin is only slightly medially convex in the congener), and the shorter distal saccular process. The phallus of
M. velona
is narrower than in
M. phantasma
. The vesica of
M. velona
is shorter than in
M. phantasma
and bearing a markedly shorter and narrower distal cornutus. Compared to
M. acutiseriata
(
Fig. 33
), the male genitalia of
M. velona
have a laterally flattened and proximally slender uncus (it is dorso-ventrally flattened and slightly proximally dilated in
M. acutiseriata
), a broader valva with a markedly larger medial dorsal protrusion of the costa (in
M. acutiseriata
, the dorsal margin is only slightly medially convex), a thicker distal costal process, a shorter and basally broader distal saccular process, and a lateral cornutus positioned on the main chamber whereas in
M. acutiseriata
, the second cornutus is terminating the elongate and distally directed dorsal diverticulum. Since the females of
M. parallelinaformis
and
M. phantasma
are unknown, the female genitalia of
M. velona
were compared only with
M. acutiseriata
(
Fig. 43
), from which the new species differs in the markedly longer and less anteriorly tapered antrum with a deeper medial ventral incision of the ostium bursae, the corpus bursae with a shorter posterior cluster consisting of smaller spines, and the larger sclerotised lateral protrusion of the corpus bursae anteriorly edged with a cluster of markedly larger spines. Additionally, the lateral pockets of the 7
th
abdominal sternite of
M. velona
are markedly broader and longer than in
M. acutiseriata
.
Distribution
. The new species is known from north-western
Myanmar
(
Chin State
), South-Western
China
(
Sichuan
), and Northern
Vietnam
(
Lào Cai Province
).
Etymology
. The specific epithet originates from the Greek ‘βελόνα’ meaning ‘a needle’ and refers to the needle-like tip of the distal costal process. The name is a noun in the nominative singular in apposition.
