Type species:
Triodia monticola
Maassen, 1890
, by present designation. Monotypic.
Diagnosis
. The pale to indistinct white markings on a ground color of sooty greyish brown is distinct from the mottled grayish brown or yellowish brown tones of
Pfitzneriella
, and the yellowish orange color tone of
Kozloviella
gen
.
nov
.
The general wing shape similar to
Pfitzneriella
, contrasting with the narrower central region of wings in
Kozloviella
gen
.
nov
.
Genitalia with a distinctive spout-shaped apex to the fused cylindrical posterioventral pseudotegumen in contrast to the unfused condition of
Pfitzneriella
and the narrow medial bar in
Kozloviella
gen. n.
The South American genera
Druceiella
(Grehan & Rawlins in press) and
Andeabatis chiliensis
(
Ureta, 1951
)
(
Nielsen & Robinson 1983
) also have a cylindrical posterioventral pseudotegumen but lack the terminal spout of
Dugdaleiella
gen. n.
The distally straight A vein of the FW separates
Dugdaleiella

from
Kozloviella
gen
.

and
Pfitzneriella
while the strongly curved A and CuP of the HW in

is unique among
Hepialidae
we have examined.
Description.
Male (
Figs 8a, 8b, 8c, 8d
): Wingspan
41–46 mm
. Wings grayish brown with broken grayish white to white band of varying intensity extending along cell between 1A and CuA2 and transversely from CuA2 to near apex.
Head
. Interocular-antennal scales present. Antenna filiform. Labial palpus with three palpomeres (
Figs
9g
, 9h
).
Thorax
. Scutum III free of scales other than posterior and medial regions, dorsally obscured by overlaying mesothorax scales. Venation hepialine (
Dumbleton 1966
), A of FW curved basally, straight distally; A and CuP of HW strongly curved (
Fig.
10i
). Metatibial gland and androconia absent (
Fig. 14f
).
Abdomen
. Tergites and sternites weakly sclerotized. Tergosternal connection with curved tergosternal bar, short lateral and dorsal brace, latter not fusing with anterior margin of tergum II, posterior edge of central region extends dorsally to fuse with anterior margin of tergum II. Tergal knob absent (
Fig. 15d
). Tergum II rectangular, anterior ridge unfused across median, strongly sclerotized, not fused with ascending tergal brace; lateral ridge strongly sclerotized (
Fig. 16h
); sternum II sub-rectangular with elongate anterior later arms with rounded apices, lateral sclerotized ridge with internal short branch, anterior margin concave with ridge not extending across centre median (
Fig.
16i
). Tergum VII subsquare; sternum VII irregularly shaped. Tergum VIII rectangular, wider than long; sternum VIII wider than long, shallow C-shape, strongly sclerotized (
Fig. 16j
).
Male genitalia
(
Figs 25a, 25b
). Tegumen narrow, indistinct from pseudotegumen. Pseudotegumen dorsally unfused dorsal- and ventrally, broad lateral shelf, margins around anogenital field postero-ventrally extended as a spout-like projection with rounded apex across median, ventral surface of spout with 3–4 shallow transverse ridges and lip-like ridge at posterior edge of the fultura superior. Saccus V-shaped with broad, triangular, post-apodemal suture region. Tergal lobes absent. Valva large, elbowed, setose. Fultura superior indistinct, slightly sclerotized; fultura inferior sub-square, concave sides. Phallus membranous without cornutus.
Female unknown.
Etymology
. It is named for John Dugdale (
Nelson
,
New
Zealand
) in recognition of his outstanding contributions to the taxonomy of
Hepialidae
, in particular his comprehensive revision of the
New
Zealand
hepialid fauna and his detailed consideration of morphological characteristics for both the adult and immature stages. The name follows the tradition of
Druceiella
and
Pfitzneriella
. The gender of the name is feminine.
