. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. New species of Crocidura 5 Crocidura ludia is similar to C. anselli but differs in its larger external (T = 60—64 mm, HF = 12-14 mm; n = 3) and cranial (CI = mm, PMH = — mm, UTRL = — mm; n = 3) measurements, although two width measurements (BW = — mm, GW = — mm) are similar, indicating that the skull of C. ludia is more compressed laterally than in most species of the C. dolichura species group. Also, the teeth, , the first upper incisor (Fig. 2) and the condylar process of the mandible of C. anselli and C. ludia are similar but differ in size. Crocidura ludia is a species of the tropical lowland forest of northern Zaire. Crocidura niobe Thomas, 1906, is with certainty known only from the Ruwenzori and Kivu mountains in eastern Zaire (Dieterlen & Heim de Balsac, 1979). It is a dark reddish brown to dark brownish-grey shrew with long bristlehairs restricted to the pro- ximal third of the tail. In external and cranial measurements it is similar to C. ludia, but the skull is less compressed laterally. From C. anselli, C. niobe differs in its larger external (T = 57—60 mm, HF = 13 — 14 mm; n = 4) and cranial measurements (CI = mm, n = 1; UTRL = mm, n = 3). Other species such as Crocidura phaeura Osgood, 1936, from Ethiopia or the widely distributed Crocidura hildegardeae Thomas, 1904, have considerably larger anselli ludia bottegi elgonius Fig. 2: First upper incisor in lateral view, and posterior surface of the condylar process of the mandible, in Crocidura anselli n. sp. (NMZ 3675, holotype); C. ludia (USNM 537685), C. bot- tegi (BM , paratype) and C. elgonius (BM , holotype). Scale = 1 mm. Relationships: It is not possible to assign Crocidura anselli to a certain species group because it exhibits a somewhat enigmatic mixture of characters found
