27–30. Galliphilopsis szeptyckii sp. nov., male. 27, dorsal view; 28, fan-like seta p’ of tarsi III; 29, peritremes; 30, opisthosoma in ventral view.

Type material. From quill of body feather of Coturnix pectoralis Gould ( Phasianidae ): female holotype, 4 female, 4 male, and 4 nymph paratypes (AMU-SYR. 327); AUSTRALIA, Adelaide, coll. Beyen. Mites collected by M. Skoracki.

Type material deposition. All material is deposited in the AMU, except 1 female and 1 male paratypes in the ZISP and 1 female paratype in the ZSM.

Additional material. From quill of body feather of Coturnix coturnix (Linneus) ( Phasianidae ): 3 females, 6 nymphs, 2 larvae (AMU-SYR. 325), JAPAN, Hokkaido, 20 September 1906. Mites collected by M. Skoracki. All material is deposited in the AMU, except 1 female in the ZSM. From quill of body feather of Coturnix chinensis (Linnaeus) ( Phasianidae ): 9 females, 1 male, 4 nymphs, 1 larva (AMU-SYR. 329); INDONESIA, Sumatra, Simpang, May 1905, coll. B. Hagen. Mites collected by M. Skoracki. All material is deposited in the AMU, except 1 female in the ZSM and 2 females in the ZISP. From Alectoris barbara (Bonaterre) ( Phasianidae ): 4 females (AMU- SYR. 13); ITALY, Sicily, no other data. Mite material is deposited in the AMU. Mites from this host species were previously assigned as G. bochkovi ( Skoracki & Sikora 2004) .

Etymology. The name szeptyckii refers to the name of the prominent Polish zoologist, our teacher and friend – Prof. Andrzej – Count – Szeptycki (9 VII 1939 – 29 IX 2008).

Differential diagnosis. G. szeptyckii is close to G. c o l i n u s and differs from this species as follows: in females of G. szeptyckii the propodonotal and pygidial shields are apunctate; each medial branch of the peritremes has 3 chambers; setae c 1 and se are situated in the same transverse level; setae f 2 are twice as long as f 1; setae h 2 are 5.7 times longer than f 1; length ratio of setae ag 1:ag 2:ag 3 is 1.2: 1: 1.8; setae 3 c are twice as long as 3 b; fan-like setae p’ and p” of tarsi III and IV are with 9 tines. In females of G. c o l i n u s, the propodonotal and pygidial shields are punctate; each medial branch of the peritremes has 1–2 chambers; setae c 1 are situated slightly posterior to the level of setae se, setae f 2 slightly (1.3 times) longer than f 1; setae h 2 are 7.5 times longer than f 1; length ratio of setae ag 1:ag 2:ag 3 is 2: 1: 2.5; setae 3 c are 1.4–1.6 times longer than 3 b; fan-like setae p’ and p” of tarsi III and IV are with 7 tines.
