Description. FEMALE. Total body length including gnathosoma 570 in holotype (495–550 in 12 paratypes). Gnathosoma. Hypostomal apex rounded and without protuberances.

MALE. Total body length including gnathosoma 375–390 in 2 paratypes. Gnathosoma. Hypostomal apex rounded and smooth. Each medial branch of peritremes with 3–4 chambers, each lateral branch with 5–7 chambers. Stylophore apunctate, 130–135 long. Idiosoma. Propodonotal shield with concave posterior margin, bearing bases of setae vi, ve, si and c1. Bases of setae se and c1 situated at same transverse level. Length ratio of vi:ve:si:c2 1:1.25:1.5:5.5. Hysteronotal shield fused to pygidial shield, anterior margin reaching to level of setae d2, setae d1, e2, f2 and h2 on margin of this shield. Distance between setae d2 and d1 half as long as the distance between d1 and e2. All hysteronotal setae subequal in length. Aggenital setae ag1 and ag3 subequal in length, both twice as long as ag2. Coxal fields I–II well sclerotized, III–IV weakly sclerotized. Legs. Fan-like setae p’ and p” with 5–6 tines. Lengths of setae: vi 15–25, ve 25–30, si 25–45, c1 <60, c2 100–120, se 120–125, d 1 15–20, d 2 20–25, e2 15, f2 20, h2 105–120, ag1 45, ag2 25, ag 3 45, 3b 15, 3c 50.

Type material. From covert quills of Penelope sp. (Cracidae): female holotype, 11 female and 3 male paratypes (AMU-SYR.135.4); GUYANA, 4 June 1938, coll. A. Fisher. Mites collected by M. Skoracki.

Type deposition. All material is deposited in the AMU, except 2 female paratypes in the ZISP and 1 female paratype in the ZSM.

Additional material. 14 females, 1 male and 1 nymph from Ortalis canicollis (Wagler) (Cracidae) (AMU- SYR. 136); PARAGUAY, 20 December 1931, coll. Kiefer. Mites collected by M. Skoracki. Material is deposited in the AMU, except 2 females in the ZSM and 2 females in the ZISP.

Etymology. The name of this new species refers to the family name of the host – Cracidae.

Differential diagnosis. Kalamotrypetes cracidus sp. nov., differs from K. colinastes Casto, 1980 by the following characters: in females of K. cracidus, total body length is 495–570; each lateral branch of the peritremes has 6–7 chambers; length of the stylophore is 150–165 long; the length ratio of setae ag1:ag2:ag3 is 2.4:1:2.4; in males all hysteronotal setae (d1, d2, e2) are short and subequal in length. In females of K. colinastes, total body length is 650–750; each lateral branch of the peritremes has 7–12 chambers; the stylophore is 200 long; the length ratio of setae ag1:ag2:ag3 is 1.2:1:1.8; in males hysteronotal setae d2 are about 3 times longer than d1 and e2.
