Revision of Afrotropical Dyscritobaeus Perkins, 1910 (Hymenoptera: Scelionidae) Tortorici, Francesco Caleca, Virgilio Noort, Simon Van Masner, Lubomir Zootaxa 2016 4178 1 1 59 Tortorici et Caleca Tortorici et Caleca [151,719,1770,1797] Insecta Scelionidae Dyscritobaeus Animalia Hymenoptera 54 55 Arthropoda species tanzaniensis sp. nov.  urn:lsid:zoobank.org:act:15CB2DAA-B68A-4C5F-A9C5-652483D9B4E6 http://hol.osu.edu/index.html?id=410572   Diagnosis.The species is brachypterous; in the Afrotropical region this feature is shared only with  D. kilimanjarensisand  D. parvipennis. On T1 the pair of longitudinal submedial carinae are absent and T1 is homogenously coriaceous; only three brachypterous species,  D. aspinosus, D. carens(female and male) and  D. minoculo(only male) from Australia have the same character state. The absence of the metanotal spine and the lack of a protruding metascutellum is shared only with  D. aspinosus,from which  D. tanzaniensisTortorici et Caleca  sp. nov.can be easily distinguished by the smaller A2–A3 ratio and darker color of the body.   Description. Male.Length of the body: 0.91 mm.   FIGURES 106–108.  Dyscritobaeus tanzaniensisTortorici et Caleca  sp. nov.Ƌ, holotype [SAM-HYM-P018754]: 106—head, frontal view; 107—head, mesosoma and metasoma, lateral view; 108—head, mesosoma and metasoma, dorsal view.  Head. Color brown. Coriaceous; head covered by short hairs, mandibles yellow. Frontal depression shallow and lightly coriaceous; central keel present ( Fig. 106). Fan-like striation in malar area from oral foramen to eye margin, fan-like striation not visible in genal area. Malar sulcus length: 0.15 mm. Preoccipital lunula present and sculptured ( Fig. 106). Head measures width: height: length = 0.37: 0.36: 0.21 mm. Eye measures width: length = 0.12: 0.16 mm. OOL: LOL: POL = 0.1: 0.1: 0.11 mm. Mandibles bidentate without odontoid process.  Antenna. Radicles and scape dark yellow; A3–  A12 brown;  A1 length: 17;  A2 as long as A3;  A11:  A12 ratio= 1:2.  Mesosoma. In dorsal view, mesoscutum brown; mesoscutellum brown with posterior margin yellow; propodeum brown to yellow in lateral margin( Fig. 108); mesosoma in lateral view light brown ( Fig. 107). In dorsal view mesoscutum and mesoscutellum imbricate ( Fig. 108); in lateral view speculum with furrow; femoral depression smooth with fan-like striation starting by post-ventral angle; posterior mesepimeral area not well delimitate anteriorly; dorsal and ventral metapleural area with crenulate depression with rugae ( Fig. 107); metapleural carina with one posterior pointed projection. Metascutellum not protruding, not visible in dorsal view, metanotal spine absent ( Fig. 108). Mesonotum length 0.24 mm, width 0.41 mm; mesoscutellum length 0.14 mm, width 0.32 mm. Wings. Fore wing hyaline, brachypterous, do not reach T1; sm: 0.17 mm; wing width 0.06 mm, length 0.19 mm. as in Fig. 40f. Legs light brown.  Metasoma. Metasoma brown; laterotergites yellow; Coriaceous. On T1 pair of longitudinal submedial carinae absent ( Figs 107, 108).  Female:unknown   Comment and variability.The description of this species is based on only a single specimen, which, however, possesses uniquely diagnostic character states: brachypterous with the rare character state where the metascutellum is not visible in dorsal view.   Distribution.( Fig. 109)   Etymology.The species is named after the country where the specimen was collected, Tanzania. Material examined. Holotype.
