First record of the family Cunaxidae (Acari: Trombidiformes) from Syria with description of a new species Author Barbar, Z. text Acarologia 2015 2015-12-18 55 4 459 465 http://dx.doi.org/10.1051/acarologia/20152185 journal article 10.1051/acarologia/20152185 2107-7207 5402877 Cunaxa celineae n. sp. Female (n=1) ( Figures 1-3 ) Gnathosoma — ( Figure 1 ). Palps consist of five segments ( Figure 1a ). Surfaces of trochanter, basifemur, telofemur, and in particular genu covered by denticles. Palpal chaetotaxy from trochanter to tibiotarsus: 0-1-1-3-5. Dorsolateral setae on the basi- and telofemora simple. Stout spine-like setae on the genua and tibiotarsi present. Apophysis of telofemur cone-like with slightly pointed apex and closer to the central part of the segment ( Figure 1a ). Proximal segment of chelicerae papillate, second segment has some denticles proximodorsolaterally and followed distally by some "furrow-like" lines in different lengths ( Figure 1b ). Chelicera terminating in a claw-like digit and with one simple seta ( Figure 1b ). The ventral surface of the hypognathum bears four pairs of simple hypognathal setae ( hg1-4 ) and two pairs of adoral setae. Hypognathum with few random papillae and short transverse lines at its base ( Figure 1c ). FIGURE 2: Cunaxa celineae sp. nov. , female idiosoma. Dorsum ( a ); venter ( b ). FIGURE 3: Cunaxa celineae sp. nov. , female. Basifemur, telofemur, genu, tibia and tarsus of: leg I ( a ), leg II ( b ); leg III ( c ) and leg IV ( d ). Idiosomal dorsum — ( Figure 2a ). Propodosomal plate with two pairs of sensillae ( vi , sce ) and one pair of simple setae ( sci ). Setae ve absent. Propodosomal plate generally smooth except for the presence of an oval area of thin broken striae around setae sci . Length of sce about 1.4 times longer than vi . Six pairs of hysterosomal setae ( c1 , c2 , d1 , e1 , f1 , h1 ) situated on small platelets. Setae f1 and h1 longer than other setae. A transverse regular striae pattern occurs between setae c1 and d1 , widely spaced between setae d1-e1 , e1-f1 and f1-h1 . Thin striae in form of broken lines in the central regions between setae e1-f1 and between setae f1-h1 . Cupule im present posteriolateral to e1 . Setae h2 occur ventrally. Idiosomal venter — ( Figure 2b ). Idiosomal venter with one pair of propodogastral, four pairs of hysterogastral, four pairs of subequal in length genital setae ( g1-4 ) and a pair of anal setae. Genital valves with longitudinal striae. Cupule ih present. Legs — ( Figure 3 ). Leg chaetotaxy: coxae I-IV, 3-1-3-2 sts ; trochanters I-IV, 1-1-2-1 sts ; basifemora I-IV, 4-4-3-0 sts ; telofemora I-IV, 4 sts -4 sts -1 asl , 3 sts -1 asl , 3 sts ; genua I-IV, {1 asl , 1 asl },{1 asl , 1 sts }, 1 asl , 4 sts -2 asl , 5 sts -1 asl , 5 sts -1 asl , 5 sts ; tibiae I-IV, {1 asl , 1 sts }, 1 asl , 4 sts -1 asl , 5 sts -1 bsl , 5 sts -1 T , 1 bbsl , 4 sts ; tarsi I-IV, 3 asl ,{1 asl , 1 fam , 1 sts }, 1 dtsl , 2 tsl , 18 sts -1 bsl , 1 dtsl , 1 tsl , 21 sts -1 tsl , 21 sts -18 sts . Surfaces of trochanters and basifemora I-IV with transverse broken striae. Remaining leg segments with papillae which on dorsal side are larger and fewer than on ventral side. Measurements — Length of idiosoma 540; width 365. Length of hypognathum 168; width 100. Length of palps 225. Chelicerae 153. Legs: I 342; II 330; III 370; IV 380. Length of setae: hg1 15; hg2 20; hg3 20; hg4 30; vi 195; sce 265; sci 22; c1 20; c2 17; d1 20; e1 16 ; f1 38; h1 38; h2 12; g1-4 12. Distance between setae sci -sci 46. Male and immature — unknown. Differential diagnosis — This new species closely resembles C. anomala Khaustov and Kuznetzov (1998) by the absence of setae ve , but differs from the latter species by possessing the following combination of characters: (1) the presence of a very short bulbous solenidion bbsl anterior to the trichobothrium on tibiae IV (absence of this seta in C. anomala ); (2) proximal segment of chelicerae papillate, second segment has some denticles proximally and dorsolaterally and followed distally by some "furrow-like" lines in different lengths (only the proximal segment is papillate in C. anomala ) (3) hypognathum with short transverse lines at its base (smooth in C. anomala ) (4) the presence of an oval area of thin broken striae around setae sci (absence of this area on dorsal propodosomal in C. anomala ) and (5) idiosomal length of C. celineae is 540 µm and about 1.5 times longer than that in C. anomala (363 µm). Etymology — The name of the species refers to the first name of author’s daughter, Celine Barbar, to whom this species is dedicated. Type material — Female holotype , Syria , Latakia Governorate , Al-Bahlouliyah , on M. sylvestris , 01 July 2012 . ( Coll. Barbar, Z. ) .
