Description LARVA (holotype; 4 paratypes). GNATHOSOMA. Porous; palpal setal formula B/B/BBB 7B.S; palpal claw three–pronged; galeala nude; cheliceral blade tricuspid, with tiny tooth at base.
IDIOSOMA. Cuticle striate except on scutum and coxae. Eyes 2/2 on ocular plate. Dorsum with 56 idiosomal setae, arranged in irregular rows; 1 pair of humeral setae (2H). Venter with 66 idiosomal setae (38 preanal and 28 postanal) and 2 pairs of sternal setae. All idiosomal setae heavily barbed.
SCUTUM. Porous; moderately rectangular; anterior margin slightly concave; lateral margins straight; posterior margin convex; 7 setae on scutum; AL base anterior to level of AM base; PL and PPL base posterior SB; AL> PL> PPL> AM; sensilla flagelliform, with slight distal branches; PW/SD = 1.51.
LEGS. All 7-segmented, with 1 pair of claws and without empodium. Leg I: coxa with 1 branched seta (1B); trochanter 1B; basifemur 1B; telofemur 5B; genu 4B, genuala and microgenuala; tibia 8B, 2 tibialae and microtibiala; tarsus 21B, tarsala, microtarsala proximal to tarsala, subterminala, parasubterminala and pretarsala present. Leg II: coxa 1B; trochanter 1B; basifemur 2B; telofemur 4B; genu 3B, genuala, without microgenuala; tibia 6B, 2 tibialae, without microtibiala; tarsus 16B, tarsala present, microtarsala proximal to tarsala, pretarsala present, without subterminala and parasubterminala. Leg III: coxa 1B; trocanter 1B; basifemur 2B; telofemur 3B, without mastifemorala; genu 3B, genuala; tibia 5B, tibiala and mastitibiala; tarsus 14B, 2 mastitarsalae. 2 claws present, without empodium on all legs. All measurements are given in Table 1 View TABLE 1 .
