Discothyrea chimera Hita Garcia & Lieberman sp. n. (Figs. 4E, 6E, 7E, 8E, 9E, 10E, 11E, 12E, 14E, 27, 28; Supp Video S5 [online only]) Type Material HOLOTYPE , pinned worker, TANZANIA, Morogoro Region, Kilosa, Mamiwa-Kisara Forest Reserve, −6.3753, 36.93711, 1989 m, primary forest, leaf litter, Winkler, collection code CEPF-TZ-1.2, 16.–21.VIII.2005 ( P. Hawkes, J. Makwati & R. Mtana ) (SAMC: CASENT0235471). Cybertype. Volumetric raw data (in DICOM format), 3D rotation video, still images of surface volume rendering, and 3D surface (in PLY format) of the physical holotype (CASENT0235471) in addition to stacked digital color images illustrating head in full-face view, profile and dorsal views of the body. The data are deposited at Dryad (Hita Garcia et al. 2019, http://doi.org/10.5061/ dryad.3qm4183) and can be freely accessed as virtual representation of the type. In addition to the cybertype data at Dryad, we also provide a freely accessible 3D surface model of the holotype at Sketchfab (Model 5). Diagnosis The following character combination distinguishes D. chimera from the remainder of the complex: masticatory margin of mandible with a conspicuous, curved subapical tooth; subquadrate head with anterolateral genal angles sharply defined; anterior clypeal margin with long erect setae; propodeum not dentate; mesotibia without apicoventral spur; petiolar node strongly attenuated dorsally and squamiform in profile (LPeI 329); AT4 around 1.2 times longer than AT3; erect setae absent on dorsal surfaces.
