Redescription.
Female
: (
Figs 15
,
16
): fully winged; length
4.3–5.6 mm
. Head black, except mandibles testaceous; occasionally clypeus and genae testaceous; antenna brown, except segments 1–2 testaceous or whitish; mesosoma black; occasionally lateral regions of pronotum with reddish nuances; metasoma brown or black; fore legs brown, except coxae and trochanters yellow or whitish; occasionally fore tarsi testaceous; mid and hind legs brown or black, except trochanters and tarsi testaceous or whitish. Antenna clavate; antennal segments of
holotype
in following proportions: 9:6:37:25:17:13:11:9:7:13; antennal segments of a
paratype
from
Malaysia
, The Gap, in following proportions: 10:5:32:23:17:12:8:7:6.5:10; antennal rhinaria present in segments 6–10. Head excavated, dull, reticulate rugose; frontal line complete; occipital carina incomplete, present behind and on sides of posterior ocelli, laterally extending beyond 0.5 length of OOL; POL = 1.5; OL = 2; OOL = 10; greatest breadth of posterior ocelli longer than OL (3:2); posterior ocelli touching occipital carina; temples distinct. Palpal formula 6/3. Pronotum dull, crossed by a strong anterior transverse impression; anterior collar and lateral regions smooth, without sculpture or weakly granulated; disc flat, rugose, with numerous irregular longitudinal keels, with a hardly visible weak posterior transverse impression (
Fig. 17
); posterior edges of pronotum rounded, not produced into lobes. Scutum dull, reticulate rugose. Notauli of
holotype
complete and posteriorly separated; minimum distance between notauli longer than greatest breadth of posterior ocelli (5:3). Notauli of other specimens hardly visible, incomplete, reaching about 0.6 length of scutum. Scutellum and metanotum dull, completely reticulate rugose. Propodeum dull, completely reticulate rugose; dorsal surface much longer than posterior surface (34:20); posterior surface with two longitudinal keels. Forewing with two dark transverse bands; marginal cell open; distal part of stigmal vein much longer than proximal part (32:11).
Hind
wing hyaline, distally darkened. Fore tarsal segments in following proportions: 27:4:8:24:40. Enlarged claw (
Fig. 18
) with a subapical tooth and a row of 21–24 lamellae. Segment 5 of fore tarsus (
Fig. 18
) with one row of 8–9 lamellae; distal apex with a group of 9–18 lamellae. Tibial spurs 1/0/2.

Remarks
:
Neodryinus malayanus
(Olmi)
was considered erroneously a junior synonym of
N. pseudodiffusus
Olmi (Olmi 1998)
. Really, these two species are different, because in
N. malayanus
the segment 5 of fore tarsus has one row of lamellae (two in
N. pseudodiffusus
) and the pronotal disc is almost flat, less humped than in
N. pseudodiffusus
(
Figs 17, 20
).
