Sinolipeurus

description: Sinolipeurus new genus
Type species: Oxylipeurus tetraophasis Clay, 1938.
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.
