Harpypalpus lonchura sp. nov.

( Figs. 5 , 9 A)

Description. FEMALE (holotype, Fig. 5 ). Body 315 long (300–315 in 2 paratypes) and 220 wide (205–220). Gnathosoma 75 long (70–75). Palp femur-genu about 35 long and 30 wide. Lengths of palpalae: dF about 30, dG about 9, l”G about 15. Idiosoma about 270 long, its striated cuticle with microscales. Propodonotal shield 110 long (100–110) and 120 wide (120–130). Setae vi, ve, si, d1, e1, and e2 thickened; most of them distinctly serrate, excluding e1 with uneven lateral margins. Setae se, c2, f1, f2, h1, and h2 filiform, distinctly serrate. Setae h1 situated anterior to level of setal bases f2; setae h2 situated distinctly posterior to level of setal bases f1. Lengths of idiosomal setae: vi and ve about 35, si, se, and d 1 25–30, c2 about 35, e1 8 –9, e2 about 15, f1, f2, and h1 35–40, h 2 27–33. Setae 3a present. Setae dF I serrate, dTr III and dTr IV extending well short of their respective tarsi, slightly thickened and serrate; setae vF III and vF IV present, slightly shorter than vTr III and vTr IV, respectively. All ventral setae of legs smooth.

MALE (2 paratypes, Fig. 9 A). Body 235–245 long and 200–210 wide. Gnathosoma 60 long. Palp femur-genu 35 long. Lengths of palpalae: dF 28, dG 10, l”G 15. Idiosoma about 185 long, its striated cuticle dorsally covered by microscales. Propodonotal shield about 170 long and 185 wide. Setae vi situated posterior to ve, distance between levels of setal bases vi and ve about 20. Distance vi–vi about 30, ve–ve about 45. Setae si, se, d1, and e2 smooth, c2, f1, h1, and h2 serrate. Distance between levels of setal bases e1–g2 and g1–g2 subequal, about 10. Lengths of idiosomal setae: si 11–12, se about 15, d1 and e 2 10 –11, c2 about 25, f1, h1, and h 2 20–22. Genital opening situated at level of setal bases d1. Leg setation as in female.

Type material. Female holotype ( OSAL 0082504), 2 female and 2 male paratypes ( OSAL 0082505–0082507, 0082529) from Lonchura castaneothorax (Gould) ( Estrildidae ), AUSTRALIA: Western Australia, Mount Hart, 17.02°S 125.07°E (GEOnet), 13 September 1976, coll. F.S. Lukoschus.

Holotype deposition. OSAL.

Etymology. The species name is derived from the generic name of the host and is a noun in apposition.

Differential diagnosis. This species is close to H. taeniopygia sp. nov. (only female known). In females of both species, setae vF III and vF IV are present, dorsal striae of the idiosoma are with microscales, setae e1 and d1 are slightly thickened, not longer than 16, setae si, d1 and e2 are distinctly serrate, setal bases h1 are situated anterior to the level of setal bases f2, setae dTr III and dTr IV extend well short of reaching the respective tarsi. These species differ from each other by the following features. In H. lonchura sp. nov., the body is 300–315 long and setae e2 are 2 times longer than e1. In H. taeniopygia sp. nov., the body is 220 long and setae e1 and e2 are subequal.

H. lonchura sp. nov. is also close to H. longipes but differs from it by the following features. In both sexes of H. lonchura sp. nov., setae dTr III and dTr IV extend well short of reaching the respective tarsi; in females, setae e1 and e2 are slightly thickened and not longer than 16, setae si, d1, and e2 are distinctly serrate, setal bases h1 are situated anterior to the level of setal bases f2. In both sexes of H. longipes , setae dTr III and dTr IV extend to their respective tarsi; in females, setae e1 and e2 are filiform, 25–30 long, setae si, d1 and e2 are smooth, setal bases h1 are situated posterior to the level of setal bases f2.
