Species inquirendae ( Saccoderma )

Saccoderma falcata Dahl, 1955:17 . Type locality: Tributaries of Sinú and from the Pechilín system. [ Colombia ]. Holotype: whereabouts unknown. [Catalog number and institution of types not designated in original description. In the description of Saccoderma falcata, Dahl (1955) mentioned “Type, male, skeletal length 30 mm. Paratypes, 158, from several tributaries of Sinú and from the Pechilín system”. However, the author did not mention in this publication nor in the following ones the catalog number and institution where this material was deposited. Types from all species and subspecies proposed in that publication are considered whereabouts unknown by Fricke et al., 2022. In 1955, Dahl collected specimens from the type locality now catalogued under CAS 149503 and identified them as Saccoderma falcata . We (FCJ) analyzed those specimens and none of them match Dahl’s diagnosis for S. falcata , being individuals of S. hastata ( CAS 149503, 15, 10.4–26.5 mm SL, Colombia , Bolivar, Pechelin, río Pechelin drainage, a small stream reduced to pools in dry season from hills near Ovejas, it flows to Golfo de Morrequillo at Tolu)].

Saccoderma robusta Dahl, 1955:18 . Type locality: Nain. [Quebrada Nain, Colombia ]. Holotype: whereabouts unknown. [In the description of Saccoderma robusta, Dahl (1955) mentioned “Type, male (from Nain) skeletal length 28 mm ”. However, the author did not mention in that publication nor in the following ones, the catalog number and institution where the specimen was deposited. The analysis of the specimens MHNG 1066.39–42 (4), listed as paratypes (Mahnert, 1976:475) and identified by Dahl as S. robusta evidenced they are specimens of S. hastata . Furthermore, they were collected in 1962, seven years after the description of S. robusta , and thus could not be considered paratypes].

Remarks: Dahl identified as S. robusta specimens from the lots CAS 149505 (collected in 1956) and CAS 149506 (collected in 1957). Those specimens were also analyzed and none of them matches Dahl’s diagnosis for this species, being individuals of Odontostilbe dialeptura ( CAS 149505) and S. hastata ( CAS 149503, CAS 149506). Considering the uncertainty of the diagnosis elaborated by Dahl for his new species, the absence of type material, and Dahl’s misidentifications of Saccoderma hastata as S. robusta , we herein consider the latter as species inquirenda ( Saccoderma ).
