description: Key to the female Prismognathus and Cladophyllus from China (using genitalic characters only)
Prismognathus sinensis, P. p i l u e n s i s and Cladophyllus nobuhikoi are not included in the following key, as their genitalia have not been examined.
1 Spermathecal duct wide. Base of spermatheca near the attachment point of the spermathecal gland thinner than spermathecal duct................................................................................... 2 (Cladophyllus)
- Spermathecal duct thin. Base of spermatheca near the attachment point of the spermathecal gland wider than spermathecal duct...................................................................................... 3 (Prismognathus)
2 Spermathecal duct about as long as hemisternite. Base of spermatheca relatively wide.............. C. oberthuri Houlbert
- Spermathecal duct shorter than hemisternite. Base of spermatheca relatively thin.................. C. bousqueti Boucher
3 Spermathecal gland obsolete, not wider than its duct.......................................................... 4
- Spermathecal gland markedly wider than its duct........................................................... 6
4 Spermatheca longer and wider than the combined hemisternites. Spermathecal duct about half as long as spermatheca....................................................................... P. kanghianus kanghianus (Didier & Séguy)
- Spermatheca neither longer nor wider than the combined hemisternites. Spermathecal duct longer than half of the spermatheca.................................................................................................... 5
5 Contracted basal portion of spermatheca markedly long and tuber-like....................... P. haojiani Huang & Chen
- Contracted basal portion of spermatheca short and conical.................................... P. arcuatus (Houlbert)
6 Contracted basal portion of spermatheca longer than or as long as half of the spermatheca.............. P. davidis Deyrolle
- Contracted basal portion of spermatheca shorter than half of the spermatheca..................................... 7
7 Spermatheca relatively large and markedly longer than the whole sclerotized part of female genitalia. Spermathecal gland about as large as hemisternite........................................................... P. klapperichi Bomans
- Spermatheca relatively small and shorter than the whole sclerotized part of female genitalia. Spermathecal gland markedly smaller than hemisternite............................................................................... 8
8 Spermatheca plus spermathecal duct about as long as the whole sclerotized part of female genitalia. Spermatheca relatively small and markedly narrower than the combined hemisternites.................................................. 9
- Spermatheca plus spermathecal duct markedly longer than the whole sclerotized part of female genitalia. Spermatheca relatively large and not markedly narrower than the combined hemisternites...................................... 10
9 Basal part of spermatheca more contracted as a tube......................................... P. nigricolor Boucher
- Basal part of spermatheca gradually contracted, not like a tube.................................. P. sukkitorum Nagai
10 Spermathecal duct approximately half the length of the spermatheca........................................... 11
- Spermathecal duct longer than half the length of the spermatheca.............................................. 12
11 Hemisternite not markedly elongate. Spermatheca without a tuber-like basal portion..................... P. siniaevi Ikeda
- Hemisternite markedly elongate. Spermatheca with a tuber-like basal portion............................................................................................... P. triapicalis (Houlbert) subspecies (outside of Sichuan)
12 Spermathecal gland plus its duct longer than half of the spermatheca......................................................... P. dauricus (Motschulsky), P. triapicalis (Houlbert) (Sichuan), P. alessandrae Bartolozzi, P. formosanus Nagel
- Spermathecal gland plus its duct shorter than half of the spermatheca........................................... 13
13 Spermatheca less sclerotized. Hemisternite more elongated.................................. P. shani Huang & Chen
- Spermatheca more sclerotized. Hemisternite less elongated............................... P. prossi Bartolozzi & Wan
