Review Of The American Genera Aspar Halašková, 1977 And Blaszakzercon Kemal & Koçak, 2009 (Acari, Mesostigmata, Zerconidae) With Description Of Three New Species Author Ujvári, Zs. text Acta Zoologica Academiae Scientiarum Hungaricae 2012 2012-08-10 58 3 275 296 journal article 10.5281/zenodo.5735834 2064-2474 5735834 Aspar HALAŠKOVÁ, 1977 Aspar HALAŠKOVÁ, 1977: 12 . Aspar : BŁASZAK et al ., 1995: 254 ; LINDQUIST et MORAZA, 1998: 210 ; DÍAZ- AGUILAR et UJVÁRI, 2010: 26 . Type species: Aspar anisotrichus HALAŠKOVÁ, 1977: 13 , by original designation. Diagnosis (female). Posterolateral tips of peritrematal shields expanded posteriorly in female. Peritremes expanded to anterior half of coxae III, straight, converging anteriorly, nearly reaching exopodal shields. Setae r1–3 shifted to peritrematal shields, each plumose, r1–2 short, r3 elongate. Genital shield narrow. Glands gv2 situated on adgenital platelets. Ventrianal shield bearing 21 setae, setae Zv1 present. Glands gv3 situated anterolaterally to adanal setae. Adanal setae longer than postanal seta. Setae z1 absent. On opisthonotum, setae J1–4, Z3–4, J5 and Z5 constitute a central series, Z1, S2, Z2 and S3–5 constitute a submarginal series. Marginal series with six pairs of R-setae. Glands Po3 associated to setae J4. Dorsal cavities inconspicuous. Epistome of Parazercon - type (see UJVÁRI 2011 ) . Remarks. Ventral pores gv2 and gv3 were not conspicuous on the specimens of HALAŠKOVÁ, but these were clearly visible on each USA specimens studied. Therefore the diagnosis is completed with the information of these structures. According to the observations on homologies of idiosomal setae of LIND- QUIST and MORAZA (1998), the genus Aspar possesses setae z1. These observations are probably based on the description and figures of HALAŠKOVÁ (1977) , where the author did not illustrate setae j1, but remarked that these setae are situated on the ventral side of the podonotal shield. However, on the basis of the species described below it seems that setae z1 are absent in the genus Aspar . The composition of dorsal podonotal setae corresponds to the figures of A. anisotrichus HALAŠKOVÁ, 1977 , but the anteriormost pair of densely plumose setae is j1 on the USA species, there are no other setae on the anteroventral edge of the podonotal shield. HALAŠKOVÁ (1977) may have overlooked the number of setae on the anterior edge of the shield and the setae marked as j 2 in the original description of A. anisotrichus are most probably setae j1. Therefore, on the modified drawing of LINDQUIST and MORAZA (1998) setae j2 are also j1, hence setae z1 should be absent, the pair of setae marked as z1 are in fact j2.
