A revision of the chigger genus Afrotrombicula (Acariformes: Trombiculidae) Author Stekolnikov, Alexandr A. text Zootaxa 2023 2023-07-31 5323 1 27 55 http://dx.doi.org/10.11646/zootaxa.5323.1.2 journal article 10.11646/zootaxa.5323.1.2 1175-5326 69FB16D4-9691-4D4D-9DEC-704BA325E07D Afrotrombicula ( Afrotrombicula ) centrafricana ( Goff, 1995 ) , comb. nov. Neotrombicula centrafricana Goff, 1995: 14 , fig. 2; Stekolnikov 2018: 179 . Diagnosis. SIF = 7BS-B-3-3111.1000; fPp = B/B/NNB; PL> AM> AL; fD = 2H-6-6-6-4-4-2; DS = 30; V = 36; NDV = 66; posterior scutal margin biconvex; f 1 at level of S 1 ; f 2 behind S 2 ; Ip = 887–905 (after Goff 1995 ). Standard measurements are in Table 4 . Type deposition. Holotype in USNM ; paratypes in USNM and BPBM , according to the original description ( Goff 1995 ). However, no material on this species was included in the recently published catalogue of the USNM collection, which currently incorporates the chigger collection of BPBM ( Bassini-Silva et al. 2021 ). Distribution and host. This species was described from an unknown locality of Central Africa ex Allenopithecus nigroviridis (Pocock) ( Primates : Cercopithecidae ). Stekolnikov (2018) noted that distribution of this host is restricted to NW DR Congo and NE Angola ( Wilson & Reeder 2005 ). Remarks. Afrotrombicula centrafricana is very similar to A. zairiensis and differs from it in the posterior scutal margin slightly concave in the central part vs. straight, and fD = 2H-6-6-6-4-4-2 vs. 2H-6-6-4-4-4-2(3). Possibly, after examination of extensive materials, A. centrafricana could be synonymized with A. zairiensis .
