Material. Five specimens, including two females and three juveniles representing two instars. Dimensions. Adult female specimen 3963 F, carapace measured before dissection: length 995 µm, height 631 µm. See also Table 1 and Figures 2 and 4. Descriptive comments. Carapace rounded-subtriangular in lateral outline, with very high-arched dorsal margin and nearly straight, steeply sloping anterodorsal and posterodorsal margins, lacking angles; greatest height 0.69 of length, located at 0.54 of length; anterodorsal corner not distinguishable, located approximately at 0.37 of length and 0.92 of height; posterodorsal corner not distinguishable, located approximately at 0.57 of length and 0.89 of height; anterodorsal brim located at 0.04 of length and 0.59 of height; posterodorsal brim located located at 0.91 of length and 0.59 of height; greatest height of ventral indentation located at 0.42 of length and 0.08 of height. Slope (measured from horizontal) of mid-dorsal margin 3 o, of anterodorsal margin 37 o, of posterodorsal margin 47 o, of dorso-caudal margin 34 o, of hinge 3 o. Caudate, with weak concavity separating dorsal-caudal margin from posterodorsal margin; length of caudal process 0.06 of length. Surface smooth, except for faint granular texture. Numerous simple setae, none very long. Seta 2 of furca with 1 or 2 unusually large proximal barbs (each side), followed by about 8 much smaller, regularly arranged barbs of decreasing size. Comparisons. B. sp. 3 is about the same size as B. balihaiensis and B. cushmani (Fig. 4). The sinuous, higharched lateral outline with distinct caudal process is shared with B. alcyonicola, B. cratericola and B. cushmani (group 3), but the (decalcified) surface is smooth, lacking the punctate texture of these and most species. The almost subtriangular LV outline resembles that of B. angolensis but has a more distinct caudal process.
