Osteochilus kahajanensis chini Karnasuta 1993

Holotype—FMNH 68230, 127.8mm SL ( Fig. 3 ). Two specimens were originally in lot FMNH 68230, and both specimens were loaned to the author. The specimens are of different sizes and the individual matching the published SL is recognized as the holotype referenced in Karnasuta (1993).

Paratypes—FMNH 126076. Karnasuta (1993) lists a second specimen of FMNH 68230 (116.7mm SL) as a paratype, with same locality data as the holotype. Correspondence during the loan transaction corroborates this is the second specimen originally in FMNH 68230, and was intended to be recognized as a paratype. As this paratype is published but never assigned a unique catalog number, this paratype is assigned FMNH 126076.

FMNH 44740. N=1, as published.

FMNH 44742. Karnasuta (1993) lists one specimen in this lot, but gives standard lengths ranging from 50.6-93.5mm and collection locality of “Kinabatangan District Dermakot, hill stream.” FMNH records for this lot, as well as locality and measurement data given in Karnasuta’s original thesis (1981) are identical. This appears to be a typo in Karnasuta (1993), and FMNH 44742 is indeed one paratype specimen of 90.8mm SL from Labuk District. The erroneous locality and measurement data given for this lot in Karnasuta (1993) actually match what is reported for FMNH 68229 in his thesis. Correspondence during the loan transaction indicates this material (FMNH 68229) was intended for designation as paratypes; however, this was not actually reported in Karnasuta (1993).

FMNH 44746. N=2, as published.

FMNH 68231. N=1, as published.

FMNH 68233. Karnasuta (1993), as well as his original thesis, lists one specimen (49.8mm SL) as a paratype of O. kahajanensis chini . This lot, which includes 32 specimens, was not loaned to Karnasuta and is not mentioned in archived correspondence. Other published information matches data for this lot; however, it is unclear which specimen Karnasuta intended to be a representative paratype from this lot, or if he intended all 32 specimens to be paratypes. Thus, 32 specimens are in this lot and considered paratypes.

FMNH 68234. N=10, as published.

FMNH 68235. N=1, as published.

FMNH 68236. N=1, as published.

FMNH 68237. N=49, as published.

FMNH 68239. N=1. Karnasuta (1993) lists FMNH 98239 as a paratype. However this is in error, and the correct catalog number for this paratype of O. kahajanensis chini is FMNH 68239. FMNH correspondence and Karnasuta’s original thesis corroborate this was as a typo in Karnasuta (1993).
