( Figs 18 View FIGURES 17–18 , 20 View FIGURES 19–20 , 32 View FIGURES 29–32 , 66–68 View FIGURES 57–68 , 87 View FIGURES 85–87 , 91 View FIGURE 91 )

Type locality. Szechwan [= Sichuan, China].

Diagnosis. Sinolipeurus sichuanensis n. sp. can be separated from S. tetraophasis by the following characters: (1) head smaller and proportionately more slender in S. sichuanensis ( Fig. 20 View FIGURES 19–20 ) than in S. tetraophasis ( Fig. 19 View FIGURES 19–20 ); (2) proximal mesosome small and with distally slightly diverging lateral margins in S. sichuanensis ( Fig. 68 View FIGURES 57–68 ), but larger and with distally converging lateral margins in S. tetraophasis ( Fig. 65 View FIGURES 57–68 ); (3) antero-lateral hooks of mesosome more pronounced in S. tetraophasis ( Fig. 65 View FIGURES 57–68 ) than in S. sichuanensis ( Fig. 68 View FIGURES 57–68 ); (4) gonopores with different shape ( Figs 65, 68 View FIGURES 57–68 ); (5) parameres with different shapes ( Figs 64, 67 View FIGURES 57–68 ).

Description.

Male. Head broad, frons broadly rounded ( Fig. 20 View FIGURES 19–20 ). Marginal carina slender. Head chaetotaxy as in Fig. 20 View FIGURES 19–20 . Lateral margins of postantennal head converging posteriorly. Thoracic and abdominal plates and chaetotaxy as in Fig. 20 View FIGURES 19–20 . Reticulation only visible on pterosternal plate, metepisterna, and sternal and subgenital plates. Antennae as in Fig. 32 View FIGURES 29–32 ; tooth-like projection of scape prominent; rugose area of flagellomere I not visible. Accessory sternal plate present ( Fig. 87 View FIGURES 85–87 ). Stylus long, slender, spatulate, distal end with sinusoid margins ( Fig. 87 View FIGURES 85–87 ). Basal apodeme broad, proximal end diffuse ( Fig. 66 View FIGURES 57–68 ). Proximal mesosome small, square-shaped, lateral margins diverging distally ( Fig. 68 View FIGURES 57–68 ); distal mesosome with slight submedian lobes, densely rugose; antero-lateral and lateral lobes as in Fig. 68 View FIGURES 57–68 . Gonopore and ventral sclerite as in Fig. 68 View FIGURES 57–68 . Parameres as in Fig. 67 View FIGURES 57–68 ; pst2 sensillus. Measurements as in Table 1 View TABLE 1 .

Female. Unknown.

Etymology. The specific epithet is derived from the type locality, Sichuan Province, China.

Type material. Holotype ♂, Szechwan [= Sichuan Province, China], Apr. 1908, R. Meinertzhagen, 3756, NHMUK0106827630 About NHMUK ( NHML).

Remarks. The slide containing the holotype of Sinolipeurus sichuanensis also has a female. This specimen differs from the male in the shape and structure of the head and the shape of the pleural incrassations; therefore, we do not regard it as conspecific with the male holotype. That female is similar, but not identical, to females of Reticulipeurus ithaginis we have examined. Thus, we believe the female on slide NHMUK0106827630 may represent an undescribed species of Reticulipeurus from Tragopan temminckii or from an unknown host.

The holotype of Sinolipeurus sichuanensis has asymmetrical sternal plates V–VII. Plates V–VI are fused on one side but separate on the other side, and plate VII is reduced anteriorly on one side ( Figs 18 View FIGURES 17–18 , 20 View FIGURES 19–20 ). No sts are present on the fused side of sternal plates V–VI, but two setae are present on the non-fused side. We regard these asymmetries to be teratologies in the single male of S. sichuanensis examined.
