Remarks. The redescription of P. huangshanensis Wu above differs from the original description in Wu (2001) in the distribution of oral collar tubular ducts. The original description mentioned that the dorsum has large ducts forming transverse bands on posterior edge of each segment; the venter has large ducts forming marginal groups from metathorax to posteriormost segment, plus one large duct between the hind legs; and small ventral ducts present on posterior edges of abdominal segments IV–VIII. In the redescription more details have been added, mentioning large dorsal ducts present near cerarii and on the upper lips of the anterior ostioles in addition to forming transverse bands; the venter having numerous large ducts in segmental groups on the margins of the abdomen, and a few on the margins of the head and thorax; and small ventral ducts present submarginally on the abdomen, on the inner edges of the groups of large ducts; forming transverse bands medially and submedially on segments II and IV–VII; and a few present on segment I submedially and on the margins of the thorax.

The adult female of P. huangshanensis is closest to that of P. barberi ( Cockerell, 1895) in having the following character states: (i) a single transversely oval circulus situated on venter of abdominal segment III; (ii) anal ring bearing sharply-tipped setae; (iii) oral collar tubular ducts absent from cerarii; (iv) dorsum without additional dorsal cerarii; (v) each anal-lobe cerarius containing 25 or more conical setae; (vi) abdomen with ventral submarginal multilocular disc-pores; and (vii) oral collar tubular ducts forming transverse bands medially on venter of abdominal segments IV–VII. Puto huangshanensis differs from P. barberi by having (contrasting character states in P. barberi given in parentheses): (i) dorsal oral collar tubular ducts present near cerarii and on upper lips of anterior ostioles, also forming transverse bands across each segment (oral collar tubular ducts absent from dorsum); (ii) large ventral ducts forming segmental groups on margins of abdomen (without marginal duct groups); (iii) few lanceolate setae present on venter (lanceolate setae absent from venter); and (iv) disc-pores each with 5, 7 or 9 circular loculi (disc-pores each with 12 loculi) (the data of P. barberi are derived from Williams & Granara de Willink (1992)).
