Diagnosis.
Female with occipital carina incomplete, distinct on sides of posterior ocelli, laterally extending beyond 0.5 length of OOL; pronotum only with an anterior very deep transverse furrow, without a posterior impression; scutum granulated, without longitudinal keels, not reticulate rugose; notauli absent; enlarged claw with a subapical tooth located very near distal apex (
Fig. 11
). Male with frontal line incomplete, shortly present between the antennal toruli; scutellum granulated; forewing hyaline, without dark transverse bands; dorsal process of parameres very long, located in distal region, with medial prominence rounded (
Fig. 12
).
Redescription.
Female
: fully winged; length usually 5.0–
6.2 mm
. Head black, except mandibles and lateral regions of clypeus yellow; antenna reddish, except ventral side of segment 1 yellow; mesosoma and petiole black; metasoma and legs reddish. Antenna clavate; antennal segments in following proportions: 36:19:105:62:52:34:22:19:16:24. Head excavated, hairy; face and vertex sculptured by many longitudinal keels; frontal line complete; occipital carina incomplete, only present behind and on sides of posterior ocelli, laterally extending beyond 0.5 length of OOL; posterior ocelli touching occipital carina; POL = 8; OL = 5; OOL = 37; temples absent. Palpal formula 6/3. Pronotum hairy, granulated, crossed by a transverse impression, sculptured by some longitudinal keels on lateral regions of anterior collar; posterior edges of pronotum rounded, not produced into lobes. Scutum and scutellum dull, granulated and sculptured by longitudinal keels, with two incomplete keels instead of notauli. Notauli absent. Metanotum very reduced and short. Propodeum reticulate rugose; posterior surface with two longitudinal keels. Forewing with two dark transverse bands; distal part of stigmal vein much longer than proximal part. Fore tarsal segment 1 longer than segment 4 (31:20). Fore trochanters about four times as long as broad. Enlarged claw (
Fig. 11
) with a subapical tooth and a row of eight bristles. Segment 5 of fore tarsus (
Fig. 11
) with two rows of about 14 + 15 lamellae; distal apex with a group of at least 15 lamellae. Tibial spurs 1/0/2.
Male
: fully winged; length
3.3–3.5 mm
. Head black, except mandibles yellow; antenna brown, ecept segments 1–2 testaceous; mesosoma black; metasoma brown; legs brown, except tarsi and fore tibiae brown-testaceous. Antenna filiform; antennal segments in following proportions: 6:6:16:12:12:12:12:10:9:10. Head hairy, granulated; frontal line incomplete, shortly present between antennal toruli; occipital carina absent; temples absent; POL = 6; OL = 1; OOL = 7; greatest breadth of posterior ocelli much longer than OL (5:1). Palpal formula: 6/3. Scutum and scutellum dull, hairy, granulated. Notauli complete, posteriorly separated; minimum distance between notauli about as long as greatest breadth of posterior ocelli, slightly shorter than antennal segment 2 (5:6). Metanotum with anterior third rugose; rest of surface shiny, smooth, without sculpture. Propodeum reticulate rugose; posterior surface without longitudinal keels. Forewing hyaline, without dark transverse bands; distal part of stigmal vein about as long as proximal part. Parameres (
Fig. 12
) with dorsal process short, slender, irregular and pointed, protruding from distal extremity of parameres, with a rounded medial prominence. Tibial spurs 1/1/2.

Biological data.
The cocoon of
N. javanus
is spun separately from the host exuvia, so that it does not stay on top of cocoon as in other
Neodryinus
(such as
N. typhlocybae
(Ashmead))
.
