Zerconella (Zerconella) leitnerae Willmann, 1953

( Figs 3–4 , 21 )

Zercon (Zerconella) leitnerae Willmann, 1953: 473 ; Petrova 1977: 591; Karg 1993: 313; Błaszak et al. 2007: 108. Zerconella leitnerae .— Ujvári 2009: 119 –121.

Diagnosis. Setae z3, s5, r3, I5, Z4, Z5 and S3–5 elongated, other dorsal setae significantly shorter. Setae J1 absent, J5 adjacent to each other. Margin of opisthonotum with seven pairs of setae. Two pairs of dorsal cavities present, each strongly sclerotised, rounded, with undulate margins, lateral pair slightly larger than medial pair. Both podonotum and opisthonotum smooth.

Distribution. Central Europe.

Remarks. The situation of the gland pores has not been described so far, because these pores are quite small and difficult to recognise in spite of the absence of dorsal ornamentation. The positions of the newly located poroid structures are the following: glands gdj2 (po1) situated anteriorly to setae j3, gdj4 seem to open anterolaterally to setae j4, gds4 posteromedially to setae s4, gdz6 on a line connecting z6 and J1, gdJ2 not conspicuous, gdJ4 on a line connecting J3 and Z4, gdS5 lying anterolaterally to S5.
