4. Cyclophorus (Glossostylus) koboensis Godwin-Austen, 1915

Cyclophorus (Glossostylus) koboensis Godwin-Austen, 1915: 495, 496, pl. 38, fig. 4, 4a-d. Nantarat et al. 2014a: 14, fig. 12a, b. Sajan et al. 2019: 25-28, fig. 1.

Type material.

Holotype NZSI M.6015/1 ( Sajan et al. 2019: fig. 1). Paratypes NZSI M.6019-20 (2 shells) from Rotung; NHMUK 1903.7.1.3045 (3 shells) from Ponging; NHMUK 1903.7.1.3117 (2 shells) from Yamme Valley; NHMUK 1903.7.1.3579 (4 shells; Nantarat et al. 2014a: fig. 12a, b) from Rotung.

Other non-type materials.

NHMUK 1903.7.1.3581 (1 shell) from between N. 28°15'-29°15'L. 94°50'-95°10'.

Specimen "No. 6015 Ind. Mus." (NZSI M.6015/1) is deemed the holotype fixed by original designation as explained above. All specimens in the remaining lots are paratypes, except for lot "No. 3581 B.M." of which Godwin-Austen (1915) stated that it "comes very close to this spices [sic; species]". We regard this as a doubtful attribution ( ICZN 1999: Art. 72.4.1). The status of the type series and of the holotype has been correctly clarified by Sajan et al. (2019), whereas the designation of a lectotype and paralectotypes from lot NHMUK 1903.7.1.3579, labelled with “Co-Type” in Godwin-Austen’s handwriting (Fig. 6B ) and recorded as “CoT” in the Register of Godwin-Austen (Fig. 7D ), by Nantarat et al. (2014a) is invalid. The type locality of this taxon is retained and restricted to "Abor Hills, Kobo, on right bank of Tsanspu or Brahmaputra River" only.
