description: Bonesioides jacobyi sp. nov.   
 Description   
 Total length. 5.7–7.0 mm (mean: 6.35 mm).   
 Head. Labrum, labial and maxillary palpus dark brown to black; frons and vertex metallic green or blue. Antenna long, dark brown to black (figure 62). Antennal article 4 longer than articles 2 and 3 combined (figure 63), A3/A4: 0.44–0.56 (mean: 0.49); article 3 slightly longer than article 2, A2/A3: 0.60–0.77 (mean: 0.70). Eyes very large (figure 62), WE/DE: 0.72–0.97 (mean: 0.91).   
 Thorax. Pronotum and elytra shining metallic green or blue. PL: 1.0– 1.1 mm (mean: 1.05 mm), PW: 1.7–2.1 mm (mean: 1.96 mm), PL/PW: 0.50–0.59 (mean: 0.54). EL: 4.5–5.6 mm (mean: 5.05 mm), EW: 2.4–3.2 mm (mean: 2.83 mm), ratio elytral width to length: 0.46–0.63 (mean: 0.56). Mesothorax, metathorax and legs black, TA/TI: 0.44–0.57 (mean: 0.52).   
 Abdomen. Dark brown to black.   
 Male genitalia. Median lobe very slender, laterally compressed in middle (figure 65). Orifice nearly circular, tectum slender and long. Endophallus slender, with two very small spiculae, one of them very tiny. Large endophallic brush and slightly protuding apical part of sclerotized ductus ejaculatorius partly covered by tectum.   
 Female genitalia. Spermatheca with small nodulus, middle part and cornu very slender, long and strongly curved (figure 64).   
 Distribution. Distributed from Cameroon and Gabon through the Congo Basin towards Uganda and Tanzania (figure 66).   
 Diagnosis. Bonesioides jacobyi sp. nov. is most similar to B. coerulea and B. caerulea (figures 7, 26). Green-coloured specimen of B. jacobyi sp. nov. can be easily distinguished from the blue-coloured B. coerulea and B. caerulea. Blue specimens may cause confusion, but such of B. jacobyi sp. nov. are smaller than those of other species. Total length of B. jacobyi sp. nov. is 5.7–7.0 mm (B. coerulea: 8.0– 8.6 mm, B. caerulea: 6.8–7.9 mm). The eyes in B. jacobyi sp. nov. are much larger and the antenna are longer than in B. caerulea (figures 26, 62; WE/DE in B. jacobyi sp. nov. 0.72–0.97, B. caerulea 0.47–0.60). Furthermore, the median lobe in B. coerulea and B. caerulea is very broad and the spiculae are very large (figures 10, 29), while the median lobe in B. jacobyi sp. nov. is much more slender and the spiculae are much smaller (figure 65).
