Type host

Pavo cristatus Linnaeus, 1758 – Indian peafowl.

Type locality

Description

Male. Frons broadly flattened ( Figure 40 ), temples not much widened, but bulging at base of mts1 and mts5. Head setae as1, as3, pcs clearly dorsal; pos, mts2, mts4 slender microsetae; head sensilla s6–7 present. Triangular extension of scape with thorn-like apical seta. Thoracic and abdominal segments as in Figure 38 ; prothorax rectangular; tergopleurite VIII without tps; accessory lateral sternal plates absent on segments II–VII. Setae of terminal male abdomen absent in single examined male, and not illustrated or described by Lakshminarayana and Emerson (1971); possibly similar to those of P. parviceps . Male genitalia symmetrical ( Figures 42–43 ). Parameres displaced dorsally, curved laterally and with microsetae near parameral head. Ventral mesosome oval, extending beyond distal margin of genital sac, anteriorly with paired central sclerites and small lateral extensions. Three pmes sensilla on each side near midline of mesosome. Genital sac with broadly V-shaped spiculation dorsally and more narrow U-shaped spiculation ventrally; central part of distal end of genital sac also spiculate on both dorsal and ventral side. Measurements as in Table 1 .

Female. Frons rounded ( Figure 39 ), temples flaring slightly, bulging at base of mts5. Head setae as1, as3, pcs ventral; pos, mts2, mts4 slender microsetae; head sensilla s6–7 present. Antennae not modified. Thoracic and abdominal segments as in Figure 39 ; psps present on tergopleurite II; accessory lateral sternal plates absent on segments II–VIII. Vulval margin variable between specimens, typically slightly convex ( Figure 44 ), with 24– 28 slender vms and 3–4 thorn-like vss on each side. Hyaline microsetae of post-vulval area restricted to posterior half of post-vulval area. Measurements as in Table 1 .
