IDIOSOMA: Cuticle striate except on scutum and coxae. Eyes 2/2 on ocular plate. Dorsum with 51 (40–54) idiosomal setae, arranged in rows with irregular number setae; 1 pair of humeral setae (2H). Venter with 43 (30–54) idiosomal setae, arranged in irregular rows and 2 pairs of sternal setae between coxae III. All idiosomal setae heavily barbed.

LEGS ( Figs. 1 E). All 6-segmented, with 1 pair of claws and empodium, both structures with onychotriches. Leg I: coxa with 2 branched setae (1a and 1b); trochanter 1B; basifemur 1 seta slightly branched; telofemur 4B; genu 4B, 2 genualae (ga) and microgenuala (k); tibia 8B, 2 tibialae (ta) and microtibiala (k); tarsus 25B, tarsala (S1), microtarsala (k) distal to tarsala, pretarsala (PT), subterminala (ST) and parasubterminala (PS). Leg II. Coxa 1B (1b slightly branched); trochanter 1B; basifemur 1B slightly branched; telofemur 4B; genu 4B, 1 genuala (g m) and microgenuala (k); tibia 6B, 2 tibialae (tm) without microtibiala; tasu 18B, tarsala (S2), microtarsala distal to tarsala and pretarsala. Leg III. Coxa 1B (3b); trochanter 1B; basifemur 1B slightly branched; telofemur 3B; genu 4B, 1 genuala (gp); tibia 6B, tibiala (tp); tarsi 16B, without mastiseta or tarsala. All measurements are given in Table 2.

Hosts. Pleurodema thaul (Lesson) ( Anura : Leptodactylidae ) and Eupsophus contulmoensis Ortiz, Ibarra-Vidal & Formas ( Anura : Alsodidae ).

Type material. HOLOTYPE larva ( MZUC 44557 ) and 9 paratypes ( MZUC 44558–44560 ; CDCA 123–128 ) collected from P. thaul , CHILE: Maule Region, Potrero Grande, Los Niches , 35° 12' 00'' S ; 70° 52' 59.88'' W, August 2012, Coll. Silva– de la Fuente, M.C. and E. contulmoensis , CHILE: Araucanía Region, Monumento Natural Contulmo, Purén , 38° 00' 51.55'' S ; 73° 10' 48.24'' W, September 2012, Coll. Castro, C.

Etymology. The name of the species is dedicated to Dr. Juan Carlos Ortiz, herpetologist, senior professor at the Universidad de Concepción, who is one of the scientists who has contributed most to the knowledge and conservation of amphibians in Chile.
