Key to species of the genus Prionoglaris (adults only)

Note: Adults of P. lindbergi are not known (see Introduction).

1A Claws of each pretarsus clearly asymmetrical. Anterior claw with a long basal seta and an internal membranous vesicle situated in basal half of claw ( Fig. 3B ). Posterior claw simple but bearing a short basal tooth ( Fig. 3C ), preapical denticle usually absent, rarely present ( Fig. 3C ), sometimes minute. Sac-like proximal part of phallosome longer than half of total length of phallosome ( Fig. 3A ). Spermapore sclerite a thin and weakly sclerotized plate, spermathecal duct running straight through the sclerite ( Fig. 3 K-L) ....................................................................... 2

1B Asymmetry of pretarsal claws less pronounced. Anterior claw with a long basal seta but lacking internal membranous vesicle ( Fig. 2C ). Posterior claw simple, lacking basal tooth and preapical denticle ( Fig. 2D ). Saclike proximal part of phallosome relatively short ( Fig. 2 H-I), about half of total length of phallosome. Spermapore sclerite a thick and heavily sclerotized plate, spermathecal duct within the sclerite curved ( Fig. 2 F-G) .................. ................................................................................................................................................... P. kapralovi sp. nov.

2A Dorso-lateral appendages of phallosome of about same width between base and broadly rounded apex ( Fig. 3I ) or only weakly narrowing towards apex ( Fig. 3 E-H) ....................................................................................... P. stygia

2B Dorso-lateral appendages of phallosome digitiform, narrow throughout except for slightly broader basal one third ( Fig. 3J )................................................................................................................................................ P. dactyloides Distribution of the genus Prionoglaris

Distributional data based on all known material, including nymphs, are here summarized. Only males and associated females and/or nymphs are assigned to one of the known species. Isolated females or nymphs are not assigned to a species (given as Prionoglaris spec. ) or are tentatively assigned to a species (given as Prionoglaris cf. stygia and Prionoglaris cf. dactyloides ). All “cf.-assignments” are based on plausibility due to the geographical position of the locality in comparison with the known distribution of male-based records.
