Pachyseius cicaki View in CoL sp. nov. ( Figs 1–2 View FIGURES 1 – 2 , 6–7 View FIGURES 5 – 9 )
Material Examined
Holotype: Ψ, NW Bulgaria, Stara Planina Mts., Vitinya village (42°47'N, 23°48'E), beech forest (Fagion sylvaticae) with admixed Carpinus betulus (2%) and Quercus sp. (1%), 970 m a.s.l., April 19, 2005. Paratypes: 1 Ψ, same data as holotype; 1 Ψ, Shipkovo village (42°52'N, 24°35'E), beech forest (Fagion sylvaticae), 650 m a.s.l., April 25, 2006.
Description (Female)
Dorsal idiosoma ( Fig. 1 View FIGURES 1 – 2 ). Dorsal shield middle-sized, length 565–575 µm, width 305–330 µm, oblong (length/width 1.73–1.87), with simple reticulate surface pattern, and 30 pairs of simple needle-like setae. Dorsal setae relatively short, j5: 22–27 µm, J5: 23–32 µm, longest anterolateral setae: 37–43 µm. All dorsal pores normally formed, not conspicuously enlarged.
Ventral idiosoma ( Fig. 2 View FIGURES 1 – 2 ). Presternal shields present, drop-like, free, strongly sclerotized, and without sculpture. Sternal shield oblong (length 144–155 µm), widely convex posteriorly, with punctiform reticulate sculptural pattern, and 3 pairs of setae and 2 pairs of pores. Metasternal shields small, oval, free in soft cuticle. Genital shield relatively short and wide (length 70–76 µm), genital pores positioned inside the shield. Ventrianal shield suboval, longer than wide, length 216–241 µm, width 193–200 µm, length/width 1.11–1.23, reticulated and bearing 3 pairs of pre-anal setae. Posterior terminal section of peritrematal shield truncate and fused to exopodal shield IV. Exopodal shield III free and abutting the peritrematal shield and exopodal IV. Area between peritrematal shield and anterolateral corner of ventri-anal shield with 2 small subequal sclerites. Metapodal shields distinctly elongate, fully free, not abutting anterolateral margins of ventri-anal shield. Lateral and opisthogastric cuticle with 8 pairs of setae.
Gnathosoma . Epistome subtriangular, widened basally, tapered toward the apex, rounded apically, and finely denticulated on distal margin ( Fig. 7 View FIGURES 5 – 9 ).
Legs. Tarsus II with 3 spur-like setae as in Fig. 6 View FIGURES 5 – 9 .
Notes
On the basis of the general appearance of the ventral shields, P. cicaki sp. nov. is very similar to P. iraola described from Spain ( Moraza, 1993). These two species may be separated by the fact that the exopodal shields IV in P. cicaki sp. nov. are fused to the posteriormost section of the peritrematal shields, while these shields in P. iraola are fully separate. In addition, P. iraola has no presternal shields, slightly spatulated dorsal setae and 12–13 setae situated on ventral and lateral soft cuticle. In P. cicaki sp. nov., the presternals are well developed, dorsal setae are simple and not modified, and 8 pairs of marginal and opisthogastric setae are present on the lateral and ventral soft cuticle.
