Durgades sineprocessus
sp. nov.
Meshram
(
Figs. 1,5,9,13
&
24–29
)
Yellow with extensive symmetrical black markings (
Figs. 1&5
) Three spots on inner margin of eye on vertex, median line on vertex continued on face as rectangular area, one transverse stripe from each ocellus to antennal ledge, upper median black spot on frontoclypeus, with submarginal row of black bulbous spots; outer & inner margin of gena and upper margin of lorum with black spots (
Fig. 9
). Pronotum with narrow median diamond shaped mark and pair of broad lateral T-shaped marks. Scutellum black with yellow posterolateral border (
Fig. 13
). Forewing with black macula on commissure between claval veins.
Male genitalia: Pygofer (
Fig. 24
) in lateral view longer than broad, caudo-dorsally strongly curved and terminated by spine and subapically forked on caudal margin. Subgenital plates(
Fig. 25
) triangular, apically obliquely blunt, with small setae throughout. Style (
Fig. 26
) broad at base with well-developed preapical lobe, apophysis long,>0.5x of total style length, blunt apically, with tooth on ventral side. Connective (
Fig. 29
) broad at base, narrowed apically with straight anterior margin. Aedeagus (
Figs. 27 & 28
) in lateral view with dorsal apodomes, mid-dorsal margin oblique to subtriangular to triangularly produced, blunt apically; preatrium of aedeagus straight, bulbous, crenulate without any process, gonopore subapical on dorsal margin.

Paratype
2♂
same data as on
holotype
.
Etymology.
The species name (Latin:
sineprocessus
meaning without process) alludes to the preatrium of aedeagus lacking elongate processes.
Remarks.
The new species closely resembles
D. aviana
Viraktamath
overall but differs in having a short, blunt projection rather than an elongate spine posteroventrally on the preatrium of the aedeagus.
Japanagallia dolabra
sp. nov.
Meshram (
Figs. 2, 6, 10, 14
&
30–36
)
Yellow with extensive black markings (
Figs. 2 & 6
).Two spots on vertex, median black line on vertex continued on face (
Fig. 10
) as inverted Y on upper part of face, two sub-marginal bands on frontoclypeus, clypellus, antennal pits, lateral frontoclypeal sulci, black. One transverse stripe encircling ocellus joining semicircular stripe. Anterior margin of pronotum (
Fig.14
) with transverse stripe continue as rectangular area on lateral margin. Scutellum with two posterolateral areas ochraceous.
Male genitalia: Pygofer (
Fig. 30
) longer than broad, broadly rounded caudally, with short, acute apical process, ventral margin concave. Subgenital plates (
Fig. 36
) triangular with pointed apex, with small submarginal setae. Style (
Fig. 32
), in lateral view, with well developed preapical lobe, outer fork rounded, inner fork shorter with basal portion strongly curved flat apically. Connective (
Fig. 34
) quadrate. Aedeagus (
Figs.
31, 3 3
–34
) with well developed elongate dorsal apodeme, with short process on dorsal margin, and pair of long blade-like processes distally, each process curved first dorsally then caudally, exceeding pygofer, with distal region slightly expanded and pickaxe shaped apically; shaft short, with two small curved spines (
Fig.35
) on mid ventral margin, gonopore large, apical; preatrium, stocky, with caudally directed lobe terminated in small conical process.

Etymology
.The species name (Latin:
dolabra
meaning pickaxe) alludes to the apically pickaxe shaped dorsal aedeagal processes.
Remarks
.
Japanagallia dolabra
sp. nov.
Externally resembles
J. palmata
Viraktamath Dai & Zhang
but can be distinguished as follows (features of
J. palmata
in parentheses): pygofer (
Fig. 30
) with ventrally and dorsally directed point process (with mesal spine on caudodorsal margin); aedeagus (
Fig. 35
) shaft short, with two small curved processes on mid ventral margin (shaft short, with small curved spine on ventral margin); long blade-like processes on dorsal margin apically pickaxe shaped (long blade-like processes on dorsal margin with their distal region slightly expanded and branched into three digitate processes).
