description: Bonesioides caerulea (Jacoby, 1903); comb. nov.   
 Barombia caerulea Jacoby, 1903: 325.   
 Barombiella caerulea (Jacoby, 1903); in Wilcox, 1973: 601.   
 Redescription   
 Total length. 6.8–7.9 mm (mean: 7.29 mm).   
 Head. Labrum, labial and maxillary palpus dark brown to black, frons and vertex dark blue metallic. Antenna short, extending towards end of mesosternum (figure 26), antennal articles dark brown to black, articles 2 and 3 rarely paler. Antennal article 3 40–50% longer than antennal article 2 (figure 27), A2/A3: 0.47–0.75 (mean: 0.63), antennal article 4 50–60% longer than article 3, about the same length as antennal articles 2 and 3 combined, A3/A4: 0.57–0.83 (mean: 0.67). Eyes small, frons broad (figure 26), WE/DE: 0.47–0.60 (mean: 0.55).   
 Thorax. Pronotum and elytra dark metallic blue. PL: 1.2–1.3 mm (mean: 1.25 mm), PW: 2.1–2.4 mm (mean: 2.20 mm), PL/PW: 0.53–0.60 (mean: 0.57). EL: 5.4–6.3 mm (mean: 5.79 mm), EW: 3.3–4.0 mm (mean: 3.59 mm), EW/EL: 0.58–0.64 (mean: 0.62). Mesothorax, metathorax and legs dark brown to black, metatibia more than twice as long as metatarsus (figure 26), TA/TI: 0.39–0.45 (mean: 0.42).   
 Abdomen. Dark brown to black.   
 Male genitalia. Median lobe broad, slightly narrowed from orifice towards end of tectum, strongly narrowed from apical third towards apex (figure 29). Orifice very broad at base, nearly circular, tectum broad and long. Endophallus with broad base and two long, left-curved spiculae; spiculae with broad base. Endophallic brush and protruding apical part of sclerotized ductus ejaculatorius partly covered by tectum.   
 Female genitalia. Spermatheca large, nodulus expanded, middle part short and nearly straight, cornu expanded in middle (figure 28).   
 Distribution. Recorded from Cameroon, Congo, Uganda and the Central African Republic (figure 11).   
 Diagnosis. Bonesioides caerulea is most similar to B. coerulea and B. godzilla sp. nov. (figures 7, 26, 58), but smaller than those with a total length from 6.8 to 7.9 mm, while length in B. coerulea range between 8.0 and 9.3 mm, in B. godzilla sp. nov. between 8.9 and 9.5 mm. The elytra of B. godzilla sp. nov. are nearly parallelsided from humeri towards the apex (figure 58), but expanded apically in B. caerulea (figure 26). The median lobe of B. caerulea (figure 29) is most similar to B. coerulea (figure 10), but the latter has a much slenderer orifice, and a nearly rectangular base. The endophallus and endophallic base are broader and the spiculae are larger in B. caerulea. Furthermore, the spiculae are left-curved in B. caerulea, while B. coerulea has each one left-and right-curved spiculum.
