. TL:
China
(

Diagnosis.
Punctulata
is similar to
Autosticha
by the forewing usually having only small dark spots or dots and by sharing a similar venation (
Fig. 2
), and to most species of
Meleonoma
by lacking a gnathos in the male genitalia. It can be separated from them by the valva with a process at the base of the costa.
Punctulata
can be further distinguished from
Autosticha
by the absence of a gnathos, which is present in
Autosticha
; from
Meleonoma
by having an ill-defined sacculus not differentiated from the valva, which is distinctly developed and distally separated from the valva in
Meleonoma
.
Revised generic characters.
Labial palpus with second segment thickened by appressed scales; third segment shorter than second, slender. Antenna about 3/5 length of forewing, scape without pecten. Forewing lanceolate, with black spots on surface, with small dark terminal dots along distal part of costal margin and termen; R
1
from about middle of anterior margin of cell and reaching basal 2/3 of costal margin, R
4
and R
5
stalked for about 2/3 length (as in
P. fusciptera
) or connate (as in
P. palliptera
), R
5
reaching apex, M
2
closer to M
3
than to M
1
, CuA
1
and CuA
2
stalked for about 1/4 length or connate, CuP vestigial. Hindwing wider than forewing; Rs and M
1
shortly stalked at base or not stalked, M
3
and CuA
1
stalked at base, CuA
2
from before angle.

Male genitalia. Uncus usually elongate subtriangular. Gnathos absent. Valva with a process at base of costa (basal process). Sacculus ill-defined. Tegumen V-shaped; lateral arms uniform or slightly narrowed anteriorly. Juxta connected with basal process of costa. Saccus usually clubbed. Phallus often with clustered spine-shaped cornuti.
Female genitalia. Apophyses posteriores longer than apophyses anteriores. Ductus bursae membranous. Signum being a basal plate with two large spines.
Distribution.
Punctulata
is currently only known from
China
(

).
Biology.
Unknown.
Remarks.
Punctulata
is proposed to be transferred from the subfamily
Oecophorinae (Oecophoridae)
into the subfamily
Autostichinae (Autostichidae)
majorly by lacking a gnathos in the male genitalia. In the family status, members of
Autostichidae
bear a gnathos extended laterally as a narrow band or lack a gnathos; in addition, Rs and M
1
of the hindwing are stalked or sometimes close basally. Members of
Oecophoridae
usually bear a gnathos expanded mesally and Rs and M
1
of the hindwing are further apart basally.
