Reticulipeurus (Forcipurellus) diki new species

( Figs 24–31 View FIGURES 24–25 View FIGURES 26–31 , 41 View FIGURES 40–44 )

Type host. Arborophila rubrirostris (Salvadori, 1879) —red-billed partridge.

Type locality. Sumatra, Indonesia .

Diagnosis. Reticulipeurus (Forcipurellus) diki can be separated from all other species in the subgenus by the following combination of characters: preantennal head more narrowly pointed ( Fig. 26 View FIGURES 26–31 ); male flagellomere I not expanded distally ( Fig. 26 View FIGURES 26–31 ); ventral sclerite of male genitalia with broadly rounded anterior margin ( Fig. 29 View FIGURES 26–31 ); male temples rounded ( Fig. 26 View FIGURES 26–31 ); male stylus spatulate ( Fig. 41 View FIGURES 40–44 ).

Description. Preantennal head somewhat pointed ( Fig. 26 View FIGURES 26–31 ). Male scape longer than female ( Fig. 27 View FIGURES 26–31 ), slightly wider but not otherwise modified; male pedicel slightly curved; male flagellomere I without distal extension. Head chaetotaxy as in Fig. 26 View FIGURES 26–31 . Lateral margins of temples rounded in male. Thoracic and abdominal segments and chaetotaxy as in Figs 24–25 View FIGURES 24–25 . Distal abdomen of male as in Fig. 41 View FIGURES 40–44 ; sternal plate VII apparently separate from subgenital plate; stylus short, spatulate; distal margin of segment XI clearly concave, lateral corners not extended distally. Male genitalia as in Figs 28–30 View FIGURES 26–31 . Distal rugosity of mesosome somewhat coarse, extensive. Ventral sclerite with broadly convex anterior margin and two visible gpmes on each side. Gonopore does not approach distal margin of mesosome. Parameres slender, convergent, with slightly bulging heads; pst 1 in distal third of paramere. Female sternal plate VII without median bulge on distal margin ( Fig. 31 View FIGURES 26–31 ). Median bulge of vulval margin moderate, with 4–6 vss on each side; lateral lobes with 19–21 long, slender vms on each side. Lateral margin of claspers with 6–9 lateral setae on each side. Measurements as in Table 1 View TABLE 1 .

Type material examined. Holotype 1♁, Sumatra, [ Indonesia], Dec. 1900, no collector, 22, NHMUK010682701 About NHMUK ( NHML) . Paratypes 1♁, 3♀, same data as holotype, NHMUK010682701–2 About NHMUK ( NHML). 1 ♁, 1♀, Sumatra, no date, coll. R . Meinertzhagen , 8344, NHMUK010682703 About NHMUK ( NHML) .

Etymology. The species epithet honours our friend and colleague Bilal Dik (Veterinary Faculty, Selçuk University, Konya, Turkey), who has systematically and meticulously examined the chewing louse fauna of Turkey for many decades, making it one of the best known of the Mediterranean and Middle East regions.
