Comments. One of the smallest Hoplasoma species characterized by a very unusual structure of male abdomen ( Fig. 2 ) with two pairs of processes. Both examined paratypes of H. minor are in bad condition. The paratype from BMNH lacks the head and pronotum, the other paratype from BPBM has the abdomen glued separately and aedeagus missing. However the unique structure of the abdomen, which perfectly fits the drawing of Haplosomoides biclavatus in JIANG (1988), allows us to synonymize both species without any doubts.
