Pachyseius morazae sp. nov. ( Figs 3–4 , 9 )

Material Examined

Holotype: Ψ, NW Bulgaria, Stara Planina Mts., Petrokhan village (43°07'N, 23°07'E), old beech forest (Fagion sylvaticae), 1,400 m a.s.l., April 20, 2005. Paratypes, 3 ΨΨ, same data as holotype.

Description (Female)

Dorsal idiosoma ( Fig. 3 ). Dorsal shield large, length 790–845 µm, width 570–600 µm, oval to widely oval (length/width 1.38–1.42), with inconspicuous reticulation and fine granulation on surface, and 30 pairs of simple needle-like setae. Medial and posterior dorsal setae relatively short (j 5 28–34 µm, J5 40–50 µm), some anterolateral setae distinctly longer (70–85 µm). All dorsal pores normally formed, not conspicuously enlarged.

Ventral idiosoma ( Fig. 4 ). Presternal shields present, subtrapezoidal, free, strongly sclerotized, and without sculpture. Sternal shield relatively large (length 163–177 µm), approximately subequal in length and width, concave posteriorly, with punctiform reticulate sculptural pattern, and 4 pairs of setae and 3 pairs of pores. Metasternal shields, both with a seta and pore, fused to posterolateral corners of sternal shield. Genital shield relatively short and wide (length 122–140 µm), genital pores positioned outside the shield. Ventri-anal shield subcordate, subequal in length and width (length 325–343 µm, width 317–343 µm, length/width 0.96– 1.07), with punctate-reticulate sculpture and 2 pairs of pre-anal setae. Posterior terminal section of peritrematal shield truncate and fused to exopodal shield IV; a hypertrophied pore-like structure present close to stigma. Exopodal shield III free and abutting the peritrematal shield and exopodal IV. Area between peritrematal shield and anterolateral corner of ventri-anal shield narrow and bearing 2 small and subequal sclerites. Metapodal shields separate, distinctly elongate and abutting the anterolateral margins of ventri-anal shield. Lateral and opisthogastric cuticle with 11 pairs of setae.

Gnathosoma . Epistome subtriangular, very finely denticulate on lateral margins, distal projection narrow and bluntly pointed ( Fig. 9 ).

Legs. Tarsus II with one massive spur-like seta.

Notes

The presence of four setae on the sternal shield, the fusion of the peritrematal shields with exopodals IV, well developed presternals, as well as 2 pairs of pre-anal setae on the ventri-anal shield and size of idiosoma are good diagnostic characters for this new species.

Etymology

This new species is named in honour of Maria Lourdes Moraza, who has contributed in a substantial way to the knowledge of the pachylaelapid mites of Europe.
