54. Dryinus teres Olmi, Copeland & van Noort , sp. nov.

( Figs 150B View FIGURE 150 , 151 View FIGURE 151 )

Diagnosis. ♀ of Dryinus with mesoscutum granulate, not reticulate rugose; notauli incomplete, reaching approximately 0.7 × length of mesoscutum; enlarged claw with apex rounded ( Fig. 150B View FIGURE 150 ), without subdistal teeth, with one row of lamellae.

Description. ♀ ( Fig. 151 View FIGURE 151 ). Fully winged; body length 4.2–4.3 mm. Head black, except mandible and clypeus ferruginous (in paratype, clypeus brown, except lateral regions ferruginous); antenna testaceous; mesosoma black, except posterior collar and lateral and anterior margins of pronotum testaceous; metasoma brown; legs testaceous- darkened.Antenna clavate; antennomeres in following proportions: 9:6:24:13:10:8:6:5:5:8; ADOs on antennomeres 6–10. Head ( Fig. 151A, C View FIGURE 151 ) dull, granulate; frontal line complete; occipital carina complete; temple distinct; lateral ocelli touching occipital carina; POL = 3; OL = 2; OOL = 8; TL = 3; greatest breadth of lateral ocelli about as long as OL. Pronotum granulate, except lateral regions partly unsculptured, crossed by slight anterior transverse impression; disc slightly humped; posterior collar short; pronotal tubercle not reaching tegula. Mesoscutum and mesoscutellum dull, granulate ( Fig. 151A View FIGURE 151 ). Notauli incomplete, reaching approximately 0.7 × length of mesoscutum. Metanotum dull, reticulate rugose. Metapectal-propodeal disc dull, reticulate rugose, about as long as propodeal declivity; propodeal declivity reticulate rugose, without longitudinal keels. Forewing ( Fig. 151D View FIGURE 151 ) with three dark transverse bands; distal part of 2r-rs&Rs vein longer than proximal part (11:6). Protarsomeres in following proportions: 16:3:6:18:30. Protarsomere 3 produced into hook. Enlarged claw ( Fig. 150B View FIGURE 150 ) without subdistal teeth, with one row of 10 lamellae, with apex rounded and not provided with lamellae. Protarsomere 5 ( Fig. 150B View FIGURE 150 ) with two rows of 8 (longer) + 16 (shorter) lamellae (5 (longer) + 14 (shorter) in paratype); apex with approximately 25 lamellae. Tibial spurs 1/1/2.
