Three water mite species of the genus Protzia Piersig (Acari: Hydrachnidia) from the Balkan, with the description of one new species Author Pesic, Vladimir M. text Zootaxa 2003 216 1 7 journal article 51325 10.5281/zenodo.157075 06248ae3-5b57-4093-b820-34cb8c988cd2 1175­5326 157075 Protzia cf. rotunda sensu Gerecke, 1996 ( Figs. 12­16 , Table 1 ) Material examined : Bulgaria : BG8 Southern Pirin, the higher part of Kalimanska river near village Vodenica, 600 m asl., 16.08.2002 , leg. Pesic (1/0/0). FIGURES 12­16. Protzia cf. rotunda sensu Gerecke, 1996 , male: 12 = coxal field; 13 = genital field; 14 = palp; 15 = chelicera; 16 = leg claws. Scale bars = 0.1 mm. TABLE 1. Protzia durmitoris nov. sp., Protzia halberti (Walter, 1920) and Protzia cf. rotunda sensu Gerecke, 1996 – leg claws, genital field and mouth parts measurements. Characters P. durmitoris nov.sp P. halberti P. cf. rotunda Paratyp, male Paratyp, female male male Remarks : Generally, e.g. with regard to the variability of idiosoma, ejaculatory complex, ratio CAc L/W, and ratio stalk L/ L of CAc, populations of Protzia cf. rotunda s ensu Gerecke, agree well with the «typical» populations of P. ro t u n d a . The specimen from Bulgaria is assigned to P. cf. rotunda and differs from typical of the P. rotunda due to the higher number of medial clawlets, 7­8 ( 5­6 in P. ro t u n d a ; in specimens of P. cf. rotunda from Southern Italy , 7­13, in most cases 9­10 [from Gerecke, 1996b ]).
