Dryinus anotaulicus Xu, Olmi, Guglielmino & Chen 2011f: 849 .

Description of Female. Fully winged; length 3.4 mm. Head black, except mandible, clypeus and gena testaceous; antenna testaceous; mesosoma black, except lateral margins and posterior collar of pronotum testaceous; metasoma brown; legs testaceous, except metacoxa basally black and club of metafemur partly brown. Antenna clavate; antennal segments in following proportions: 8:6:22:8:7:7:6:6:5:8. Head almost flat, dull, granulated, without longitudinal keels or striae on face, except complete frontal line; occipital carina complete, laterally not reaching eyes; temple distinct; posterior ocelli almost touching occipital carina; POL = 3; OL = 4; OOL = 8; OPL = 0.5; TL = 5; greatest breadth of posterior ocelli shorter than TL (2:5). Pronotum shiny, crossed by one only strong posterior transverse furrow (anterior transverse impression absent); anterior collar and lateral regions unsculptured; disc weakly humped, granulated; posterior collar short, sculptured by longitudinal striae; pronotal tubercle not reaching tegula. Scutum, scutellum and metanotum granulated, not rugose. Notauli absent. Propodeum reticulate–rugose, without longitudinal and transverse keels; dorsal surface longer than posterior surface (22:16). Fore wing with three dark transverse bands; distal part of stigmal vein longer than proximal part (17:7). Hindwing hyaline. Protarsal segments in following proportions: 17:3:6:16:25. Enlarged claw not spatulate ( Plate 85F ), with one large subapical tooth and one row of six lamellae + one bristle. Segment 5 of protarsus ( Plate 85F ) with two rows of 17 lamellae; distal apex with at least 20 lamellae. Tibial spurs 1/1/1.

Group 3

Six species are known in the Oriental region.

Key to the females

1. Notauli present and incomplete.......................................................................... 2

- Notauli absent........................................................................................ 3

2. Occipital carina complete; segment 5 of protarsus with three–four rows of lamellae extending without interruption to distal apex ( Plate 86B ); enlarged claw with only one medial lamella, ( Plate 86B )......................... D. asiaticus (Olmi)

- Occipital carina incomplete; segment 5 of protarsus with two rows of lamellae, interrupted near distal apex ( Plate 86E ); enlarged claw with many medial lamellae ( Plate 86E )........................................ D. gibbosoides Olmi

3. Fore wing hyaline, without dark transverse bands............................................. D. orientalis (Olmi)

- Fore wing with one–two dark transverse bands.............................................................. 4

4. Head weakly reticulate rugose, with areolae small; scutellum granulated, with weak areolae near lateral margins................................................................................................ D. peterseni (Olmi)

- Head strongly reticulate rugose, with areolae wide; occasionally only face reticulate rugose, then vertex with strong longitudinal keels; scutellum completely strongly reticulate rugose..................................................... 5

5. Posterior ocelli touching occipital carina; enlarged claw without lamellae ( Plate 88A )..................... D. viet (Olmi)

- Posterior ocelli not touching occipital carina; enlarged claw with distal lamellae ( Plate 86C )........... D. barbarus (Olmi)

Remarks. Fossil species of Dryinus group 3 were described by Olmi & Guglielmino (2011).
