SCUTUM ( Fig. 2 A): Pentagonal with anteromedial projection (naso), 6 setae on scutum. Setae AM slightly branched compared with AL and AP. AM <AL <AP. Sensillae flagelliform with very small branches at tip. PW/ SD = 1.

IDIOSOMA: Cuticle striate except on scutum and coxae. Eyes 2/2 on ocular plate. Dorsum with 56 (40–56) idiosomal setae, arranged in rows with irregular number of setae; 1 pair of humeral setae (2H). Venter with 46 setae (42–56) arranged in irregular rows and 2 pairs of sternal setae between coxae III. All idiosomal setae heavily barbed.

LEGS ( Figs. 2 E, 3). 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, 4 genualae (ga) and microgenuala (k); tibia 8B, 2 tibialae (ta) and microtibiala (k); tarsus 26B, 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 (gm) and microgenuala (k); tibia 6B, 2 tibialae (tm) without microtibiala (k); tasu 18B, tarsala (S2), microtarsala (k) distal to tarsala and pretarsala (PT). Leg III. Coxa 1B (3b); trochanter 1B; basifemur 1B slightly branched; telofemur 3B; genu 4B, 1 genuala (gp); tibia 6B, tibialae (tp); tarsi 16B, without mastiseta or tarsala. All measurements are given in Table 2.

Hosts. Eupsophus nahuelbutensis Ortiz, Ibarra-Vidal & Formas ( Anura : Leptodactylidae ).

Material. HOLOTYPE larva ( MZUC 44561 ) and 5 paratypes ( MZUC 44562–44563 ; CDCA 129–131 ) collected from E. nahuelbutensis , CHILE: Biobío Region, Cerro Pichinahuel , Cordillera de Nahuelbuta, 37° 35’ 40.00” S ; 73° 03’ 34.00” W, August 2012, Coll. Castro, C.
