Diagnosis and history This species was described from a female specimen, with a juvenile as a paratype ( Gerstaecker 1883 ). At ZIMG, only the paratype remains ( Fig. 28 ) and the female holotype is most likely lost, as previously suggested ( Rehn 1933 ). This species has three junior synonyms, described and illustrated by Borg (1902) , synonymized by Princis (1962) , and whose types are deposited at NHRS ( Fig. 29 ). Kumar (1975) included this species in his key to species of Rhabdoblatta found in West Africa and the Congo Basin; the male specialization on the 4 th adbominal tergite is a diagnostic character (Kumar erroneously mentioned the 5 th tergite in his key; see Fig. 30 and Princis 1962 ). Genitalia of the male specimen from LUHM were already prepared; they are pictured here ( Fig. 30G ) for the record although hardly visible. Fig. 30.
