(Figs. 12–14) Trombicula chaetosa Brennan and Jones, 1961 : 193 , fig. 11 ( holotype in USNM, paratypes originally in USNM and RML). Toritrombicula (Whartonacarus) chaetosa, Vercammen-Grandjean 1965a : 59 . Neacariscus (Whartonacarus) chaetosa, Vercammen-Grandjean & Langston 1976 : 963 , pl. 278. Diagnosis. SIF = 7BS-N-2-3111.1000; fPp = B/N/NNN; fCx = 1.1.1; fSt = 2.2; fSc: PL> AM> AL; Ip = 1058– 1172 ; fD = (4–7)H-(24–35)-(20–29)-(12–22)-(10–20)-…; DS = 92–122; VS = 70–97; NDV = 167–214. Eyes large, 2 + 2; scutum rectangular, densely covered with small puncta; sensilla flagelliform, nude, sometimes with inconspicuous cilia; all scutal and idiosomal setae pointed; microtarsala I (f1) distal to tarsala; 3 genualae I (two in proximal and one in distal half of genu); nude mastitarsala III. Standard measurements of material examined given in Table 4 . Hosts. Microlophus peruvianus (Lesson) . New host: Microlophus atacamensis (Donoso-Barros) . Distribution. Peru , Piura Region. Here this species is recorded in Chile , Atacama Region for the first time. Material examined. Twenty seven specimens ( ZIN collection Nos. 8222–8249) ex Microlophus atacamensis Nos. 19 and 20, CHILE : Atacama Region, Pan de Azúcar National Park, 2 and 5 April 2010 , coll. D. González- Acuña & S. Muñoz-Leal. Remarks. Given that the original description of this species is incomplete and its redescription made by Vercammen-Grandjean and Langston (1976) is hardly accessible, here we provide figures and measurements of our material (Figs. 12–14, Table 4 ).
