Description. FEMALE (holotype, Figs. 53 , 55 A–D). Body, including gnathosoma, 565 long and 600 wide. Gnathosomal length and width subequal, about 150. Palp 100 long and 65 wide. Lengths of palpalae ( Fig. 55 A): dF 31, dG 37, and l”G 24. Setae vF 135 long, smooth. Subcapitulum without ventro-lateral projections. Peritrematal branch 75 long. Idiosoma 400 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. All dorsal setae, excluding h2, serrate. Dorsal shield unornamented, 190 long and 255 wide, trapezoidal in shape, with rounded angles and almost straight anterior and posterior margins. Idiosoma ventrally without scales or verrucosities, distinctly striated. Coxal fields I and II with posterior fold. Lengths of setae: vi, ve, si, se, and c2 130–140, h2 about 115. Solenidion ω 1 I 6 long, ω 1 II 12 long, narrow slightly curved and conical, with rounded apex. Femora and genua I and II completely fused dorsally and separated from each other ventrally. Femora-genua I and II bearing 2 setae, dF and vF. Leg III with 1 articulated segment bearing 6 setae. Leg IV with 5 setae.

MALE (1 paratype, Figs. 54 , 55 E, F). Body, including gnathosoma, 500 long and 400 wide. Gnathosomal length and width subequal, about 135. Palp 85 long and 65 wide. Palpalae strongly different in length ( Fig. 55 E): dF 24, dG 19, and l”G 17. Setae vF 85 long, smooth. Subcapitulum ventrally as in female. Idiosoma 385 long. Smooth cuticle between peritrematal branches and transverse striations apunctate. Dorsal shield 285 long and 335 wide; with straight anterior and posterior margins. Aedeagus 115 long, straight, situated posterior to genital opening. Genital opening situated in median part of dorsal shield. Genital arch 25 long. Genital setae 2–3 long; setae g2 situated almost at same level with setal bases g1. Distance g1–g1 35, g2–g2 38, and g3–g3 19. Setae vi 16 long, ve, si, se, and c2 —all serrate, 120–135 long. Idiosoma ventrally without scales or verrucosities, fully striated. Coxal fields I and II smooth. Leg I and II setation as in female, except genua I and II with 3 setae (d, l’, v’). Solenidia ω 1 I and ω 1 II about 12 long, narrow slightly curved and conical, with rounded apex. Apical segment of leg III with 5 setae; preapical segment with 1 setae. Leg IV with 4 setae.

Type material. Holotype female ( OSAL 0083653) and 1 male paratype ( OSAL 0083655) from Carduelis tristis (Linnaeus) ( Passeriformes : Fringillidae ), USA: Wyoming, Campbell Co., Gillette, 19.3 km E of, 44.29°N 105.5°W (USGS-GNIS), 29 August 1962, coll. W.W. Moss.

Type deposition. Holotype and paratype in OSAL.

Etymology. This species is dedicated to Tina Penekof , a former custodian at UMMZ.

Hosts and distribution. Carduelis tristis ( Passeriformes : Fringillidae ) from USA (Wyoming) (present paper). Differential diagnosis. The new species differs from all other representatives of this genus by the genua and femora I and II fully fused dorsally and completely separated ventrally (completely fused in Crassacarus alexfaini sp. nov. or separated in four remaining species).
