Morelacarus sp. 1

Diagnosis. SIF = 5B-B-3-2000.1000; fsp = 6.6.6; fCx = 2.1.1; fSt = 0.2; fPp = B/B/ BNN; fD = 2H-[8-4]-6-8-6- 6(4)-5(2). Cheliceral blade with ventral row of 2 teeth and dorsal row of 4 teeth; sensilla with 9 branches in distal half; SB situated at level of PLs; mastitarsala III with 2 cilia in proximal one-third. Standard measurements of 2 specimens: AW 43, 48, PW 57, 61, SB 18, 18, ASB 21, 23, PSB 16, 16, SD 37, 40, P-PL 16, 16, AP 19, 22, AM 18, 19, AL 18, 18, PL 23, 22, S 52, -, H 24, 25, D min 16, 16, D max 23, 22, V min 20, -, V max 23, -, pa 243, 250, pm 207, 207, pp 225, 236, Ip 675, 693, DS 45, 40, VS 20, 25, NDV 65, 65, TaIIIL 62, 63, TaIIIW 13, 13.

Hosts. Liolaemus curicensis Müller and Hellmich and L. schroederi Müller and Hellmich.

Distribution. Chile, O’Higgins Region, Colchagua Province, Termas del Flaco.

Material examined. Six specimens ( ZIN collection Nos. 8528–8533) ex L. curicensis No. 235, CHILE: Termas del Flaco, 3 April 2013, coll. D. González-Acuña; 1 specimen (8535) ex L. schroederi No. 368, Termas del Flaco, 6 April 2013, coll. D. González-Acuña.

Remarks. Two measured specimens are similar to M. camanchaca by the fPp, presence of mastitarsala, and measurements of scutum and setae, but differ in longer legs (Ip 675–693 vs. 617–630) and fD = 2H-[8-4]-6-8-6- 6(4)-5(2).
