Kirejtshuk, A. G.: Notes on the systematics of the African Nitidulidae (Coleoptera)

1925"; 3 (NRS, ZISP) - "Durban, MJÖBERG"; Zambia: holotype of P. puncticollis (NHL) - "Lake Bangwculu dist., IX-XII.1946, M. Steele"; 1 paratype of P. puncticollis (NHL) - "Lake Bangweulu, N'Chit Island, 16.X.1946, M. Steele"; Zimbabwe: 3 (NHL, ZISP) - "Matopo Hills, E.A.C. Schelpe, 1954 (3920), ex flowers of Protect lanceolata E. Mey ex Meissn."; Democratic Republic of Congo (Zaire): 2 paratypes of P. puncticollis (MRAC) - "Katanga, Kisanga, ii,1925 (Seydel)". Notes - The name concolor was synonymized with magna REITTER, 1872, obscurci, and name crassa GROUVELLE, 1906 was regarded as a probable pretender to be synonimized with them as well (KIREJTSHUK 1996). Additional specimens allow to find some regular differences and reconsider this previous interpretation. At the moment, three of the mentioned names can be recognized as valid to fix three distinct species: P. concolor, P. magna and P. crassa, but names obscura and puncticollis should be regarded as junior synonyms of the first of the listed names (if the specimen designated as the lectotype by COOPER is conspecific with paralectotype studied by the author of this paper). This species is characterized by absence of well developed sexual dimorphism in shape of antennái club (although male club usually looks somewhat larger than that of female). This is the most expressive difference of this species from P. magna (see below) (sympatric to the species under consideration) and P. crassa (known only from Madagascar). The male of both last species are different due to their 4-segmented male antennái club (some males of P. magna from Fish Hoek have 5-segmented club - see below), however the male club of P. magna usually is dark and rather long (at least twice as long as wide), while that of P. crassa is very wide and comparatively short (about 1 and 1/3 as long as wide). P. "concolor" in comparison with P. magna has also wider and more convex body with slightly conspicuous and comparatively short pubescence, denser and finer punctation of dorsum, lack of bronze shade and rather smoothed sculpture, but in comparison with P. crassa it has not only different male antennái club but also more widely rounded elytral apices. Besides, three mentioned species are similar to P. parviclava sp. n. (see below). At the same time, the relations between P. "concolor" and P. crassa, as well as between both these and P. magna remain still not clear. The studied paratypes of P. pectinicomis looks very similar to typical specimens of P. concolor (including widely and separately rounded elytral apices), but have male antennái club as that in P. crassa and female antennái club similar to those in some females of P. magna from Fish Hoek (see below). According to the original description the holotype of P. pectinicomis seems to belong to a species very different from P. concolor and the paratypes mentioned above.
