Ng, Peter K. L., 2010, On the Planopilumnidae Serène, 1984 (Crustacea: Brachyura: Pseudozioidea), with diagnoses of two new pilumnoid genera for species previously assigned to Planopilumnus Balss, 1933, Zootaxa 2392, pp. 33-61 : 59

Planopilumnus fuscus Balss, 1933: 40 , text fig. 5C, pl. 6 fig. 30. “ Pilumnus ” fuscus —Ng et al. 2008: 141.

Material examined. Lectotype (here designated): male (7.3 × 5.4 mm) ( ZMB 23359, ex MB 5096), Grand Harbour, New Ireland province (= New Mecklenburg), northeastern Papua-New Guinea, coll. “Gazelle”.

Paralectotypes: 1 ovigerous female ( ZMB 23359, ex MB 5096), same data as lectotype; 1 male, 1 female ( ZMB 13816), New Guinea, “Friedrich Wilhemschafen”, coll. H. Schoede.

Diagnosis. As for genus.

Remarks. The species was described from four specimens from Papua New Guinea but no specimen was selected as the holotype. All four specimens are thus syntypes. The male figured ( Balss 1933: pl. 6 fig. 30) is figured here and designated as the lectotype; the remaining three specimens are paralectotypes. The species was probably inadvertently omitted in Serène’s (1968: 86) list of Planopilumnus species.
