Toluk, A., Ayyildiz, N. & Subías, L., 2009, Three New Species Of The Family Oppiidae (Acari, Oribatida) From Turkey, Acta Zoologica Academiae Scientiarum Hungaricae 55 (1), pp. 11-21 : 12-15

Multioppia (Multioppia) turcica sp. n.

( Figs 1–9 )

Diagnosis: Protuberance between rostral setae present; lamellar line absent; sensilli unilaterally pectinate, with eight branches; notogaster with twelve pairs of thin, sparsely barbed setae; genital setae five pairs.

Measurements – Body length: 504–532 ( holotype: 504), body width: 260–304 ( holotype: 260). Totally five specimens were measured.

Prodorsum ( Figs 1, 3, 4 ): Rostrum rounded. Rostral setae ( ro) 56 in length, arising on the dorsolateral sides of the rostrum, unilaterally barbed. There is a protuberance between rostral setae. Lamellar setae ( le) 22 in length, smooth. A few tubercles situated on each side of prodorsum anterior to bothridia. Distance between lamellar and interlamellar setae shorter than that between rostral and lamellar setae. Interlamellar setae ( in) 12 in length, unilaterally barbed; between these setae there are three pairs of areola in two longitudinal rows. Sensilli ( ss) 80 in length, pectinate, with eight branches.

Notogaster ( Fig. 1 ): Oval, twelve pairs of notogastral setae thin, sparsely barbed, 24 in length. Along the lateral margins of notogaster present a number of muscle sigillae.

Ventral plate ( Figs 2, 5 ): Length of infracapitulum 100, width 72. Setae h 11 in length. Distance between setae h and h 22 in length. Pedotectum I ( pd 1) narrowed anteriorly. Epimeral borders easily visible and well sclerotized. Epimeral regions with internal muscle sigilla. Apodemata apo 1, apo 2, apo sj and apo 4 well developed. Epimeral setal formula 3–1–3–3. Genital plate 38 in length, 36 in width, with five pairs of setae; anal plate 48 in length, 48 in width, with two pairs of setae. Lyrifissures iad situated in paraanal position. Adanal setae ad 1 in postanal, ad 2 in paraanal and ad 3 in preanal positions. The shape of the ovipositor is as given in Fig. 5 .

Legs: All legs monodactylous; setation of leg segments is given in Figs 6–9 .

Material examined: Holotype and nine paratypes, soil under Pinus nigra , N 39°48.163’, E 34° 48.682’, 1546 m, 5 Mar. 2006; one paratype, soil and litter under Pinus nigra , N 39°48.255’, E 34°48.578’, 1484 m, 19 Jan. 2006; four paratypes, soil under Quercus spp. , N 39°48.410’, E 34° 49.136’, 1404 m, 1 Dec. 2006, Yozgat, Turkey.

Etymology: The specific name, “ turcica ” is named after the locality, Turkey, where the present new species was found.

Remarks: Multioppia (M.) turcica sp. n. is close morphologically to M. (M.) glabra ( MIHELČIČ, 1955) and M. (M.) tenue MAHUNKA and MAHUNKA- PAPP, 1999 by the shape of sensilli. The characters differentiating these species are listed in Table 1 .
