Pachyseius pachylaelapoides   sp. nov. ( Figs 5, 8 View FIGURES 5 – 9 )

Description (Female)

Dorsal idiosoma. Dorsal shield middle-sized (length 523 µm, width 302 µm), oblong (length/width 1.73), with delicate punctate-reticulate surface pattern, and 30 pairs of simple needle-like setae (dorsal shield almost identical to that as in Fig. 1 View FIGURES 1 – 2 ). Dorsal setae short (j 5 18–22 µm, J 5 23–33 µm, longest anterolateral setae 25–35 µm). All dorsal pores normally formed and not conspicuously enlarged.

Ventral idiosoma ( Fig. 5 View FIGURES 5 – 9 ). Presternal shields absent. Sternal shield slightly oblong (length 132 µm), widely convex and slightly truncate posteriorly, with punctiform reticulate sculptural pattern, and 3 pairs of setae and 2 pairs of pores. Metasternal shields small, oval and free in soft cuticle. Genital shield relatively short and wide (length 73 µm), genital pores positioned outside the shield. Ventri-anal shield subpentagonal, widest at the middle, slightly longer than wide (length 219 µm, width 200 µm, length/width 1.1), with reticulate-punctate ornamentation and 3 pairs of pre-anal setae. Posterior terminal section of peritrematal shield truncate and fused to exopodal shield IV. Exopodal shield III free, abutting the peritrematal shield but well separated from exopodal shield IV. Metapodal shields very enlarged, subtriangular, with punctate-reticulate pattern and a pore. Anterior and inner margins of metapodals adjacent to peritrematal and ventri-anal shields respectively. A pair of small suboval sclerites present close to anterolateral corners of ventri-anal shield. Lateral and opisthogastric cuticle with 7 pairs of setae.

Gnathosoma   . Epistome subtriangular, very finely denticulate on lateral margins, distal projection bluntly pointed ( Fig. 8 View FIGURES 5 – 9 ).

Legs. Tarsus II with 3 spur-like setae as in Fig. 6 View FIGURES 5 – 9 .

Notes

This new species can be easily recognized by its greatly expanded metapodal shields.
