(Figs. 2; 3; 10A; 10B)
Diagnosis. Dorsal setae slightly serrated, except smooth trichobothria. Serrated setae on tibia III and IV, all genua, femur I, II and III and trochanter III. Dorsal ornamentation mostly striated (type “ Tydeus ”), with small reticulated areas on anterior aspidosoma and between setae bo, c1, d1 and f1; reticulated areas do not reach setal bases; aspidosomal reticulated area not reaching setal bases. Palptarsi eupathidium (pζ) straight and sharp.
Dorsum (Figs. 2 A; 10A): Prodorsum recurved. Twelve pairs of slightly serrated setae, length 9–15 (Fig. 2 F; Fig. 10 B) and filiform, smooth trichobothria (bo) (Fig. 1 G). Dorsal striation type “ Tydeus ” (Kaźmierski 1998), with reticulation on aspidosoma and small reticulated areas between bo, c1, d1 and f1 that do not reach setal bases (Fig. 2 H). Setae f1 shorter than distance f1–h1. Lyrifissure ia (Fig. 2 B) posterior to c2, in sublateral position, nearing 2/3 distance between c1-c2. Lyrifissure im (Fig. 2 C) posterior to ia, slightly anterior to e. Dimensions: Length of idiosoma 193 (192–212) and width 145 (135–154). Dorsal setae: ro 10 (10–14), la 11 (10–12), bo 31 (31–36), ex 10 (10–14), c1 10 (8–14), c2 12 (10–14), d 11 (8–13), e 10(7–14), f1 13(11–15), f2 13(12–17), h1 12(12–15), h2 12(12–16), ps1 12 (8–15).
Venter (Fig. 3 A): Ornamentation on metasternal region with “V” like striation, anogenital region with six pairs of genital setae, four pairs of aggenital and one pair of pseudanal setae.
Gnathosoma (Fig. 1 A, 1B): Gnathosoma visible from above. Palp setal count 6+1ω –2–2. Tarsus (Fig. 3 B) with straight eupathidium, without terminal dilation. Palp length 45 (42-47), tarsus elongate, length 18 (16-18), width 4 (3-4).
Legs: Serrated setae dorsally inserted (Fig. 2 D, E) on tibia I (l’), tibia III (l”) tibia IV (l”), genu I (l’, l”), genu II (l’, l”), genu III (l”), genu IV (l’), femur I (d), femur II (d), femur III (l’) and trochanter III (tr). All tarsi with terminal claws and hairy empodium, empodial hook present (Fig. 3 D). Solenidion ω I short and thin, as long as half of tarsal width. Solenidion ω II very short. Oval coxal organ (Fig. 3 C). Vestigial seta k on tibia I spatulated (Fig. 3 D). Leg lengths: I 101 (82–109), II 79 (77–90), III 133 (88–133), IV 135 (90–135).
Etymology. The new species name is formed by Latin words parvi (small) and reticuli (nets), due to the presence of small reticulated areas on the dorsum.
Specimens examined. Holotype female from H. brasiliensis, clone FX3864 from Igrapiúna, Bahia State (13° 48' S, 39° 10' W), 11 December 2008, F. M. Nuvoloni coll; 10 paratypes females from H. brasiliensis, clone FDR 5788, from Igrapiúna, Bahia State, collected on May, June and September 2008, E. B. Castro e F. M. Nuvoloni coll. Specimens deposited at Acari collection DZSJRP. Male not found.
Remarks. The new species resembles Lorryia opima (Kuznetzov & Zapletina, 1973) due to the pattern of striation type “ Tydeus ”, reticulated pattern on the aspidosoma, acute and serrated dorsal setae, palptarsus longer than stylets, ventral striation with “V” pattern between metasternal setae, and solenidion ω I as long as width of tarsus I. The two species can be distinguished by the following characters: dorsum with reticulate patches on aspidosoma and hysterosoma (reticulate patch only on aspidosoma in L. opima); empodial hooks present on all tarsi (hooks absent in L. opima); length of f1 setae about 2/3 of f1–h1 distance (length f1 setae about half of f1–h1 distance in L. opima); and body length 192–212 (312 in L. opima).
