Figures 6 , 18-19 , 21 , 32-33 , 34-39 Description. Whorl of setae on flagellomeres in male: absent. Shape of A3-A11 in male: cylindrical. Color of antenna in male: brown. Color of antennae in female: A 1 brown, A2 brown to yellow, A3-A5 yellow with white setae, A6-A16 brown. Color of mesosoma: black, with yellow metascutellar spine. Color of head: black. Setation of torular triangle: absent. Continuity of torular triangle and central keel: torular triangle closed dorsally, continuous complete central keel. Setation of frons: area above interantennal process glabrous, otherwise setose. Sculpture of dorsal frons: dorsoventrally strigose. Sculpture of vertex: smooth; concentrically strigose. Epomial carina: absent. Netrion in lateral view: present only at ventral limit of pronotum. Ventral propleural area: smooth. Sculpture of propleural cervical sulcus: smooth. Sculpture of mesoscutum: punctate to finely areolate, coarser in posterior half. Density of setation on medial mesoscutum: dense. Notaulus: absent; weakly indicated posteriorly amid sculpture. Sculpture of scutoscutellar sulcus: smooth. Orientation of transaxillar carina: parallel to longitudinal axis of body. Shape of axillula: bent ventrolaterally distally. Sculpture of mesoscutellum: punctate to areolate. Density of setae on lateral margin of mesoscutellum: sparse. Posterior margin of mesoscutellum: concave between mesoscutellar spines. Median mesoscutellar spine: absent. Lateral extreme of posterior scutoscutellar sulcus: foveae extending to axillula. Sculpture of metanotal trough: smooth with elongate furrow in ventral half. Lateral propodeal carina: absent. Plica: present. Forewing pattern in female: wing membrane and setae brown posterior to marginal vein and in distal third, separated by a band of hyaline membrane and white setae. Forewing color in male: uniform throughout. Sculpture of metapleural sulcus: transverse portion smooth, dorsoventral portions foveolate. Sculpture of dorsal metapleural area: smooth. Sculpture of ventral metapleural area: transversely rugose; smooth. Number of setae on lateral T1: 3; 4. Sculpture of T4: smooth. Lateral patch on T5: absent. Number of apical setae on T7: 4. Transverse line of pits on anterior S1: present. Diagnosis. Dvivarnus mikuki can be separated from D. agamades and D. elektrolythron by the glabrous torular triangle and by the color of the mesosoma, which is entirely black except for the metascutellar spine. Additionally, D. mikuki can be separated from D. agamades by the absence of an epomial carina, the form of the metanotal trough, which is non-foveolate and is dorsoventrally divided by a transverse furrow, and by the banding pattern on the wings of females. From D. elektrolythron it can be separated by the broad lateral patch on T4 and the convex posterior margin of the mesoscutellum between the mesoscutellar spines. Etymology. The word " Dvivarnus mikuki " means "spears" in Swahili, the language of Kenya where the holotype specimen originates, and refers to the many spines found on the mesosoma. The name is treated as noun in apposition. Link to distribution map. http://hol.osu.edu/map-large.html?id=403211 Material examined.
