Osteocheilus sarawakensis Karnasuta 1993

Holotype—FMNH 94182 ( Fig. 2 ). Karnasuta (1993), as well as his original thesis, list “FMNH…..” as the catalog number for the holotype. Correspondence shows the catalog number FMNH 94182 was to be assigned for this specimen (138.5mm SL), and this is the correct FMNH catalog number for the holotype of O. sarawakensis .

Paratypes—FMNH 44737. N=2, as published.

FMNH 68530. Karnasuta (1993) lists 20 specimens as paratypes in this lot, as does Karnasuta’s original thesis (1981). Upon examination of correspondence at the time of the loan transaction, it seems apparent Karnasuta (1993) likely took the count of 20 from FMNH 68908, which was listed on the next line of correspondence regarding the request of catalog numbers for newly designated type specimens. Fifty specimens, instead of 20, were sent on loan to Karnasuta and included in correspondence regarding the number of specimens to be included as paratypes in FMNH 68530. All individuals in FMNH 68530 are confirmed as O. sarawakensis , and this lot should now be 50 instead of 20 paratype specimens. The remaining 37 specimens of O. sarawakensis originally in FMNH 68530 are now FMNH 126071 (nontypes).

FMNH 68531. N=1, as published.

FMNH 68534. Karnasuta (1993), as well as his original thesis, lists two separate entries of FMNH 68534, designating both jars as paratypes, with the same catalog number. Based on FMNH records, this lot originally consisted of three specimens and was never loaned out or referenced in loan transaction correspondence. Indeed FMNH 68534 includes 3 paratype specimens, a combination of the two entries listed separately in Karnasuta (1993).

FMNH 68535. N=2, as published.

FMNH 68536. N=2, as published.

FMNH 68537. N=1, as published.

FMNH 68538. N=5. Correspondence between Karnasuta and FMNH Division of Fishes indicates the five specimens in this lot were to be designated as paratypes. However, given this lot was not listed as paratypes in Karnasuta (1993), the five specimens in this lot are considered non-type material for O. sarawakensis .

FMNH 68539. N=1, as published.

FMNH 68882. This specimen was not loaned out to Karnasuta, nor is it mentioned in any archived correspondence. However, Karnasuta (1993) lists a paratype specimen of O. sarawakensis as “FMNH 6882” with matching count, standard length, and locality data as FMNH 68882. In addition, Karnasuta’s thesis (1981) correctly lists the paratype specimen as FMNH 68882. This appears to be an error in Karnasuta (1993), and the correct catalog number for this paratype is indeed FMNH 68882.

FMNH 68906. Karnasuta (1993) and Karnasuta (1981) list incorrect data and numbers of specimens. This seems likely due to confusion with locality data of FMNH 68908 and count data of FMNH 68538, the next entries in archived correspondence. Nine specimens (not five) were loaned out and indicated as paratypes in correspondence. All specimens were received together (seven fluid specimens and one cleared and stained specimens—one cleared and stained specimen is missing). Thus, the count of this lot of paratypes should be nine instead of five.

FMNH 68908. Karnasuta (1993), as well as his original thesis, lists seven specimens in FMNH 68908 as paratypes of O. sarawakensis . Correspondence regarding catalog numbers for the 1993 publication indicates that 20 specimens were to be designated as paratypes in this lot. Indeed 20 specimens from the lot were loaned to Karnasuta for study. It is likely the published count of 7 was from FMNH 68906, the next line in correspondence. The count of this lot of paratypes should be 20 instead of seven.

FMNH 68892. N=7, as published.

FMNH 68912. N=1, as published.

Paratopotypes—Karnasuta (1993) lists “FMNH…..” with a count of 49 as paratopotypes. Based on archived correspondence, the catalog number of this lot is FMNH 68532 (N=49). The additional 34 specimens originally in FMNH 68532 were designated as topotypes per correspondence (now FMNH 126070).
