Rhinibius tamandua Brennan and Yunker Rhinibius tamandua Brennan and Yunker 1969: 304; Brennan and Reed 1975: 63; Nadchatram 1970: 4; Jacinavicius et al. 2018: 14. (Figures 1–4 and 9, Tables 1–4) Diagnosis Larva. Palpfemur with a single branched seta; palpgenu with a single nude seta; palptibia with a dorsal and a lateral nude seta, and a branched ventral seta; adoral setae (cs) nude; prodorsal sclerite subtrapezoidal with punctuations; ve (= AL) seta branched; coxal field III with one branched seta (2b); Ta III with a mastiseta. Redescription Larva (holotype, four paratypes and nine additional specimens). Gnathosoma – fPp = B/N/NNB/7Bωζ; odontus trifurcate; curved cheliceral blade with tricuspid cap and inner tooth; gnathobase punctate, subcapitular setae (bs) branched and adoral setae (cs) nude (Figure 1 (A,B)). Idiosoma – no eyes; prodorsal sclerite subtrapezoidal with punctations, anterior and lateral margins slightly sinuous, with convex posterior margin (Figures 2 and 9 (A)); trichobothria (si) fusiform, covered with small triangular setules; pair of branched ve (= AL) setae and a single branched vi (= AM) seta and pair of branched se (= PL) setae on posterolateral projections of prodorsal sclerite; se> si> vi> ve; opisthosoma (Figure 3 (A,B)) with 40 setae; dorsal opisthosoma with 20 setae, C row with 4 pairs of setae (c 4 = humeral setae), D row with 3 pairs of setae, E row with 2 pairs of setae, and F row with 1 pair of setae; H row with 1 pair bordering dorsal and ventral margins (not shown in the holotype); 20 ventral opisthosomal setae with 10 setae anterior to anus and 10 setae posterior to anus. Two pairs of sternal setae: first pair (1a) located between coxal fields I, and second pair (2a) between coxal fields III. Legs (Figure 4) – femur of legs I–III each divided into basifemur and telofemur, each leg terminates with paired claws and a claw-like empodium without onychotriches, coxal fields punctate. Leg I – coxal field seta (1b) 1B; trochanter 1B; basifemur 1B; telofemur 5B; genu 4B, 3 σ and microseta Κ; tibia 8B, 2 φ and Κ; tarsus 22 to 23B with ω, ε, dorsal eupathidium (ζ’) with companion seta (z) and subterminal eupathidium (ζ), base of famulus (ε) distal to ω (Figure 4 (A)). Leg II – coxal field seta (2b) 1B; trochanter 1B; basifemur 2B; telofemur 4B; genu 3B, σ; tibia 6B, 2 φ; tarsus 15 to 16B with ω, ε and subterminal eupathidium (ζ), base of ε proximal to ω (Figure 4 (B)). Leg III – coxal field seta (3b) 1B (Figure 9 (B)); trochanter 1B; basifemur 2B; telofemur 3B; genu 3B, σ; tibia 6B, φ; tarsus 14B and 1 mastiseta (MTa) (Figure 4 (C)). Remarks The analysis of the type series revealed some discrepancies in the original description. The odontus was initially described as bifurcated, but our examination of the type series revealed it to be trifurcate. Additionally, one of the branched setae of the palptibia was mistakenly identified as dorsal when it is ventral. Another inconsistency was the presence of eyes mentioned in the original description, but the eyes are absent. We provide illustrations of all structures and a detailed description of the leg setae, which were omitted in the original description by Brennan and Yunker (1969). In addition, the original description included an incomplete set of metric data (standard measurements of the prodorsal sclerite with its setae, lengths of specialised leg setae, and the length and width of body) only for the holotype. In the current study, we update these measurements and include additional all the standard measurements currently used in trombiculids. We also provide measurements for all the paratypes and additional material. Type material examined HOLOTYPE: larva (USNMENT01760183); BRAZIL: Pará State, Belém Municipality, Utinga State Park; 20 March 1968; ex Tamandua tetradactyla; C.E. Yunker coll.; RML 49365. PARATYPES: 4 larvae (USNMENT01760184, USNMENT01760185, USNMENT01760186, USNMENT01760187); same data. Additional material examined VENEZUELA: 8 larvae (RML 59318); Monagas State; 8 June 1968; T. tetradactyla (cited as Tamandua longicaudata); Smithsonian army coll.; 1 larva (RML 49116); VENEZUELA: Bolívar State, Gran Sabana Municipality, Icabarú; 8 May 1968; unidentified Rhipidomys Tschudi, 1845; C.E. Yunker coll.
