Lorryia amazonensis

sp. nov.

Lorryia amazonensis  sp. nov.

( Figs. 4View FIGURE 4; 5; 10C; 10D)

Diagnosis. Pointed, slender, serrated dorsal setae, except for filiform, smooth trichobothria (bo). Palptarsus eupathidium (pζ) straight, with a “T” shaped distal dilation. Dorsal striation type “ Tydeus  ”, without reticulated areas.

Dorsum ( Figs. 4View FIGURE 4 A; 10C): Prodorsum recurved. Twelve pairs of serrated and acute dorsal setae, of medium length ( Figs. 4View FIGURE 4 D; 10D), and filiform, smooth trichobothria (bo) ( Fig. 4View FIGURE 4 E). Dorsal striation type “ Tydeus  ” ( Kaźmierski 1998) ( Fig. 4View FIGURE 4 F), without reticulated areas. Lyrifissure ia ( Fig. 4View FIGURE 4 B) posterior to c2, in sublateral position, nearing half of distance between c1-c2. Lyrifissure im ( Fig. 4View FIGURE 4 C) posterior to ia, anteriorly to e. Dimensions: Idiosoma 190 (180–195) length, and 125 (120–125) width. Dorsal setae: ro 12 (11–13), la 13 (10–13), bo 28 (28–30), ex 12 (11–13), c1 12 (11–12), c2 12 (8–12), d 13 (11–13), e 14 (12–14), f1 15 (11–15), f2 15 (12– 15), h1 16 (11–16), h2 15 (11–15), ps1 8(8–12).

Venter ( Fig. 5View FIGURE 5 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. 1View FIGURE 1 A, 1B): Gnathosoma visible from above. Palp setal count: 6+1ω –2–2. Palptarsus eupathidium straight, terminating into a T-shape. Palp dimension 53 (46-53), tarsus ( Fig 5View FIGURE 5 B) elongate, length 14 (14-17), width 3 (3-4).

Legs: Nude leg setae. All tarsi with terminal claw and a hairy empodium, empodial hook present ( Fig. 5View FIGURE 5 D). Solenidion I (ω I) short and thin, as long as half of tarsal width. Solenidion ω II very short. Oval coxal organ ( Fig. 5View FIGURE 5 C). Small seta k on tibia I spatulated ( Fig. 5View FIGURE 5 D). Measures of each leg: leg I 92 (70-92), leg II 76 (62-76), leg III 83 (64-83), leg IV 83 (64-83).

Etymology. The new species’ name refers to Amazon forest, where the holotype was collected.

Specimens examined. Holotype female from H. brasiliensis  without cloning classification, from an experimental area maintained by ‘ Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) situated at the rural area of Manaus city (59°98’ W, 3°09’ S), 09 July 2012, F. M. Nuvoloni collGoogleMaps  ; 5 paratypes females from H. brasiliensis  , from a rubber plantation at Rio Branco city, km 15 of BR 364, Acre State (67º85’ W, 9º95’ S), collected on August 2012, F. M. Nuvoloni collGoogleMaps  ; 3 paratypes females from H. brasiliensis  , clone FDR 5788, from Igrapiúna , Bahia State (13° 48’ S, 39° 10’ W), collected on October 2008, E. B. Castro coll. Specimens deposited at Acari collection DZSJRP. Male not found.GoogleMaps 

Remarks. The new species resembles Lorryia tuttlei ( Baker, 1965)  , due to dorsal striation type “ Tydeus  ” ( Kaźmierski 1998), absence of reticulation, eupathidium (pζ) broadened distally, acute and serrated dorsal setae, solenidion ωI about half the width of tarsus, presence of empodial hooks and gnathosoma visible from above. The species are distinguished by following characters: small body—female idiosomal length 180-195 µm, width 120- 125 µm (large body in L. tuttlei  —female idiosomal length 504 µm, width 306 µm), length of dorsal setae about 12 µm (very short in L. tuttlei  ), six pairs of genital setae (five pairs of genital setae in L. tuttlei  ), and distal dilation of eupathidium (pζ) with a “T” shape (distal dilation of eupathidium (pζ) with a goblet shape in L. tuttlei  ).
