Taxonomic notes
. The genus
Lyclene
is heterogenous and includes numerous species groups of unclear taxonomic position, having significantly different male genital structures. Both
Lyclene
and
Miltochrista
have well developed distal costal and saccular extensions (in some cases the costal extension can be absent in
Lyclene
), and lack both medial costal and basal saccular extensions.
Holloway (2001)
did not give a detailed comparison of
Lyclene
and
Miltochrista
, and besides characteristic appearance of most of
Lyclene
representatives (but far from all), differences can be found only in the vesica structure in males and sclerotization of anterior part of corpus bursae in females. Unfortunately, a female of
M. tibeta
is unknown therefore female genitalia cannot be used for an additional comparison. According to
Holloway (2001)
,
Miltochrista
(
Figs 8
,
13
) has large, well separated cornuti in the vesica, whereas
Lyclene
(
Figs 7
,
12
) in most cases has a small number of large cornuti (usually one-two), or, rarely, a bunch or a band of slenderer spine-like cornuti. According to this indistinct criterion,
L. tibeta
comb. nov.
could be placed in
Miltochrista
by having a subapical band of large and well separated cornuti and a medio-lateral cluster of smaller spine like-cornuti, like the
type
species of
Miltochrista
,
M. miniata
(
J.R. Forster, 1771
)
.
Nevertheless, the vesica of
M. miniata
(
Fig. 13
), as well as those of other 'true'
Miltochrista
(e.g.,
M. rosacea
(
Bremer, 1861
)
,
M. ziczac
(
Walker, 1856
)
,
M. calamina
Butler, 1877
, etc.) (
Figs 14-16
) have different structure: the large cornuti in vesica of
Miltochrista
are situated on a large medio-dorsal diverticulum, and a bunch of several smaller cornuti (or one large cornutus) is situated on a large medio-ventral diverticulum, whereas the all cornuti of
tibeta
are situated within one oblong-globular medial diverticulum like in
L. clara
and other
Lyclene
species. For this reason,
L. tibeta
comb. nov.
should be placed in
Lyclene
and not
Miltochrista
.
Redescription
.
Adult
(
Figs 3, 4
). Wingspan
25-27 mm
. Male antennae finely ciliate. Body slender, reddishochreous. Forewing broad, with rounded apex. Ground colour of forewing reddish-ochreous, pattern reduced to slight blackish suffusion in cell and between veins in central part of wing, and short black stokes on veins in subterminal area. Cilia reddish-ochreous. Hindwing paler than forewing, ochreous.
Male genitalia
(
Fig. 10
). Uncus long, moderately curved, narrow, subapically somewhat broadened, apically pointed; tuba analis broad, membranous; scaphium narrow, weakly sclerotised; subscaphium broad, as wide field of strong scobination; tegumen moderately long and broad; manica narrow, with strong scobination; juxta large, shield-like, with two ventral lobes broadly trigonal, with setose margins; sacculus large, U-like. Valvae long and narrow, costa strongly sclerotised, basal part forming a narrow sclerotised lobe, apical extension trigonal, relatively short, with elongated and pointed tip; apical lobe of valva short and broad, rounded; sacculus moderately sclerotised, its apical extension strongly sclerotised, apically pointed, not extending beyond the valva apex. Aedeagus long and narrow, slightly curved; vesica curved latero-dorsally, its basal section with strong scobination ventrally; medial diverticulum broad, ovoid, with conical additional diverticulum apico-laterally, four large and strong cornuti distally and short band of spine-like cornuti medio-laterally; apical dorsal diverticulum small, bilobate; basal sclerotised plate of ductus ejaculatorius strongly sclerotised, long and narrow. Female unknown.
