Male : unknown Etymology The name corvinae refers to the specific name of the host ­ Corvinella corvina Differential diagnosis Syringophilopsis corvinae sp. n. is most similar to Syringophilopsis yosefi Skoracki, Tryjanowski, Hromada, 2002 from Lanius sp. ( Laniidae ) by having the following characters: the setae d4 and d5 are short; hypostomal apices is with two pairs of median protuberances; pygidial plate is present; total body length is longer than 1000. The new species is distinguishable from S. yosefi by the presence of following characters: In the female S. corvinae sp. n. propodosomal plate is slightly ornamented ( Fig. 9 ); pygidial plate is concave on anterior margin ( Fig. 10 ); distances between setal bases vi­vi and sci­d1 are 115­ 130 and 90­105 respectively (ratio vi­vi:sci­d1 is 1,2:1); distances between setal bases 1c­ 1c , 2c­2c and 1c­2c are 125­140, 145­175 and 120­130 respectively (ratio 1c­1c:1c­2c:2c­ 2c is 1,1:1:1,3); the epimeres I are fused to epimeres II at middle part of epimeres II ( Fig. 11 ); the legs III are thick ( Fig. 12 ) ­ the length of tarsus III is 46; the width of trochanter III is 41­48; ratio wide of trochanter III: length of trochanter III is 1:0,9­1,1. In the female S. yosefi ( type material) propodosomal plate is strongly ornamented ( Fig. 13 ); pygidial plate is convex on anterior margin ( Fig. 14 ); distances between setal bases vivi and sci­d1 are 90­95 and 125­140 respectively (ratio vi­vi:sci­d1 is 1:1,4); distances between setal bases 1c­1c , 2c­2c and 1c­2c are 90­95, 105­130 and 145­165 respectively (ratio 1c­1c:1c­2c:2c­2c is 1:1,5­1,8:1,2­1,4); the epimeres I are fused to epimeres II at anterior part of epimeres II ( Fig. 15 ); the legs III are thin ( Fig. 12 ) ­ the length of tarsus III is 55­60; the width of trochanter III is 30; ratio wide of trochanter III: length of trochanter III is 1:1,5.
