Diagnosis. Sinolipeurus n. gen. is most similar to Reticulipeurus , sharing the following characters: (1) at least some abdominal plates with reticulation (extent variable among species); (2) antero-lateral corners of mesosome with hooked extensions; (3) distal margin of mesosome rugose; (4) gonopore originating in proximal end of mesosome; (5) similar structure of male genitalia; (6) frons rounded; (7) male scape and pedicel much enlarged; (8) tergopleurites II–VIII medianly separated in the male (female of Sinolipeurus is unknown); (9) male subgenital plate formed by fusion of sternal plates VIII–IX+X. However, Sinolipeurus can be separated from Reticulipeurus by the characters given above, under the diagnosis of Reticulipeurus . Description. Male. Head broad, frons rounded ( Fig. 19 ). Marginal carina uninterrupted. Dorsal preantennal suture absent. Extensive internal thickenings present posterior to marginal carina across most of head. Head chaetotaxy as in Fig. 19 and 95 ; as2–3 clearly dorsal; avs3 situated far anterior, near vsms1–2 ; mds absent; mts3 macroseta; s2 , s4 , s6 absent, sizes as in Fig. 95 . Coni short. Antennae presumably sexually dimorphic, but female unknown; male antennae as in Figs 31–21 , scape and pedicel large, scape with triangular tooth-like projection; flagellomere I with hook-like extension distally and may have rugose area. Eyes not prominent. Gular plate indistinct. Prothorax with 1 dorsal anterior seta ( pdas ), 1 pronotal marginal-lateral seta ( pmls ) and 1 pronotal postspiracular seta ( ppss ) on each side. Pterothorax with 1 anterior and 1 posterior submarginal meso-metanotal seta ( asmns and psmns , respectively), 1 pterothoracic trichoid seta ( ptrs ) and 1 pterothoracic thorn-like seta ( pths ) on each side. Marginal pterothoracic setae in two discrete clusters on each side ( Fig. 19 ). Leg chaetotaxy as in Fig. 91 ; cII-a3 and cIII-a3 dorsal. Postero-lateral corners of pterothorax not extended into horns. Abdomen rather stout, reticulation visible only on sternal plates ( Fig. 19 ). Tergopleurites II–VIII medianly separate, tergopleurite IX+X medianly continuous, not fused with tergopleurite XI. Inter-tergal plates absent. Sternal plates present on segments II–VII. Accessory sternal plate present lateral to subgenital plate on segment IX+X. Subgenital plate formed by fusion of sternal plates VIII and IX+X, distal end extended to terminal end of abdomen, underlying slender, spatulate, and centrally arising stylus ( Figs 86–87 ). Male genitalia as in Figs 63–68 . Basal apodeme broad, proximal end diffuse. Mesosome large, seemingly separate from basal apodeme; antero-laterally with prominent hook-shaped extensions on each side; proximal mesosome variable in shape ( Figs 65, 68 ); distally bilobed with extensive rugose nodi; postero-laterally with secondary rugose nodi. Gonopore arising in proximal end of mesosome, not reaching distal margin; in anterior end associated with large ventral sclerite with recurving lateral ends; 2–3 small pores on gonopore on each side. Parameres S-shaped, slender ( Figs 64, 67 ); pst 1 in proximal half, pst2 subapical. Female. Unknown. Host distribution. Species of Sinolipeurus are parasitic on members of the genera Tetraophasis Elliot, 1871 and Tragopan . These two bird genera form a clade together with Lophophorus Temminck, 1813 in the family Phasianidae of the order Galliformes ( Meng et al . 2008 ; Liu et al . 2014 ). Geographical range. China . Etymology. Sinolipeurus is constructed from “ Sinae “, Latin for “Chinese”, referring to the known geographical range of the two species included in the genus, and the name of the related genus Lipeurus Nitzsch, 1818 . Gender: masculine.
