Description of Female. Fully winged; length usually 5.0– 6.2 mm. Head black, except mandible 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 (granulated and reticulate rugose among 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; temple absent. Palpal formula 6/3. Pronotum hairy, granulated, crossed by 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 rugose, sculptured or not by longitudinal keels (among which two incomplete keels instead of notauli). Notauli absent. Metanotum very reduced and short. Propodeum reticulate rugose; posterior surface with two longitudinal keels. Fore wing with two dark transverse bands; distal part of stigmal vein much longer than proximal part. Protarsal segment 1 longer than segment 4 (31:20). Protrochanter about four times as long as broad. Enlarged claw (Plate 93D) with one subapical tooth and one row of eight-nine bristles. Segment 5 of protarsus (Plate 93D) with two rows of about 25–29 lamellae; distal apex with at least 15 lamellae. Tibial spurs 1/0/2.
Description of male (Plate 94). Fully winged; length 3.4–3.5 mm. Head black, except mandible yellow; antenna brown, ecept segments 1–2 testaceous; mesosoma black; metasoma brown; legs brown, except tarsi and protibia 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; temple 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, unsculptured. Propodeum reticulate rugose; posterior surface without longitudinal keels. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein about as long as proximal part. Paramere (Plate 95A) with dorsal process short, slender, irregular and pointed, protruding from distal extremity of paramere. Tibial spurs 1/1/2.
Material examined. Types: ♀ lectotype of P. javanus (designated by Olmi, 1984): INDONESIA: Java, Salatiga, Assinan (BMNH); ♀ holotype of P. thoracicus: PHILIPPINES: Palawan Island, Puerto Princesa (USNM); ♀ holotype of N. lawanae: MALAYSIA: Malaya, Kuala Lumpur, 8.III.1938, G.H. Corbett leg., associated with Lawana conspersa (BMNH). Paralectotype of P. javanus: INDONESIA: Java, Salatiga, Assinan, VII.1913, W. Roepke leg., 1♀ (BMNH); paratypes of N. lawanae: MALAYSIA: same locality label as holotype, ♂ allotype, 2♀♀ and 1♂ (BMNH). Other material. MALAYSIA: Malaya, Kuala Lumpur, 5.V.1938, G.H. Corbett leg., associated with Lawana conspersa, 3♀♀ and 2♂ (BMNH); Malaya, Perak, Teluk Intan (= Teluk Anson), 30.XI.1983, reared by MARDI from a nymph of Lawana conspersa, Azhar leg., 1♂ (BMNH).
Hosts. Flatidae (Guglielmino & Olmi, 1997): in Malaysia (Malaya): Lawana conspersa (Walker) and Lawana candida (Fabricius) (Roepke, 1916).
Biology. The study of cocoons deposited in BMNH, proved that the cocoon of N. javanus is not spun under the host cast cuticle, so that this exuvia is not located on top of cocoon (as in Neodryinus typhlocybae (Ashmead)).
Distribution. Indonesia (Java), Philippines (Palawan), Malaysia (Malaya).
