( Figs 88E , 96B )

Deinodryinus sabaeus Olmi & van Harten 2006: 314 ; Guglielmino & Olmi 2015: 252 .

Description. ♂. Fully winged; body length 1.1–2.4 mm. Head black, except mandible testaceous; antenna brown, except scape and pedicel testaceous; mesosoma and metasoma black; legs brown, except tarsi, protibia and stalk of profemur testaceous. Antenna filiform, with setae longer than breadth of antennomeres; antennomeres in following proportions: 7:4.5:4.5:4.5:4.5:4.5:4:4.5:4.5:6.5. Head shiny, slightly granulate and rugose or with irregular striae (in many specimens strongly granulate and rugose); vertex without two oblique keels from lateral ocelli to occipital carina; frontal line complete; occipital carina complete; POL = 7; OL = 3.5; OOL = 5; OPL = 2; TL = 2. Mesoscutum shiny, partly very slightly granulate and partly punctate and unsculptured among punctures (rarely mesoscutum completely unsculptured). Notauli thin, incomplete, reaching approximately 0.25–0.30 × length of mesoscutum (0.4 × in specimen from Kenya, 0.22121°N 37.11998°E). Mesoscutellum and metanotum shiny, unsculptured. Metapectal-propodeal disc ( Fig. 96B ) dull, reticulate rugose, with transverse posterior keel; propodeal declivity completely reticulate rugose, without longitudinal or transverse keels. Forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein much shorter than proximal part (1.5:7). Paramere ( Fig. 88E ) with one very large and long inner branch not showing mosaic pattern. Tibial spurs 1/1/2.

♀. Unknown.

Material examined. Types: ♂ holotype: YEMEN: Ar Rujum , 15°26’N 43°40’E, 9.IV–5.VI.2001, MT, A. van Harten leg. ( MOLC). Paratypes: YEMEN: same locality label as holotype , 13♂♂ ( MOLC). Other material: KE- NYA: Rift Valley Prov. , Lolldaiga Ranch, 0.22121°N 37.11998°E, 2061 m, 10–14.XII.2013, MT, in meadow near small dam, R. Copeland & J. Muriuki leg. , 1♂ ( NMK) .

Hosts. Unknown.

Distribution. Kenya, Yemen.

Remarks: Deinodryinus sabaeus is similar to Anteon madagascolum ( Benoit 1954) , but with the inner branch of the paramere much longer and more transverse ( Fig. 88E ). The record from Madagascar reported by Azevedo et al. (2010) is incorrect: it should be referred to Anteon madagascolum .
