HYALOMI'lA SCHULZEI Olenev, 1931(B).

THE NEAR EASTERN CAI'lEL HYALOl-H-'Jl 



H. schulzei a hyalomma of restricted geographical range, appears 

 from male characters to be a giant relative of H. dromedarii . The fe- 

 male genital apron, however, differs so greatly'from that of H. drome - 

 darii that the relationship of these two species does not appear to 

 be actually so close as previously considered. It is also likely 

 that females associated by Olenev with males of H. schulzei in the 

 original description of the species included some specimens of K. 

 dromedarii . 



The geographic range of H. schulzei extends from Iran (Olenev 

 1931A,B, Delpy 1937) and Afgh"anistan ^Anastos 195^), through Iraq 

 (Hoogstraal, ms.), and Palestine (Schulze 1936C; Kratz 19A-0, Adler 

 and Feldman-Muhsam 194-6, 19A.8) into Sinai and the Eastern and V/estern 

 Deserts of Egypt some 200 miles west of Alexandria (Hoogstraal, ms.). 

 It is absent in Russia (Pom.erantzev 1950) aJ^d is not represented in 

 the present collections from Libya, Yemen, coastal East Africa, or 

 Turkey . 



Hosts of adults mentioned by all authors and represented in our 

 collections are camels, and Pomerantzev (1950) adds cattle. Hosts 

 of immature stages have not previously been determined. In Sinai 

 and Egypt (Hoogstraal, ms.), nymphs (reared to adults) have been 

 fo\ind on hares, Lepus capensis subsp., and fat sandrats, Psammom^'s 

 o. obesus . Unfed, newly molted adults have been taken from bur- 

 rows of jirds, Heriones c. crassus . 



The male is large and when engorged measures up to 8,00 mm. 

 in length and 7.00 ram. in width. The extreme width is due to con- 

 siderable lateral stretching of the integument during feeding; vin- 

 engorged specimens are approximately ^.00 mm. wide. The scutum 

 of specimens at hand and previously described has parallel lateral 

 margins while those of H. dromedarii are usually convexly arched. 

 The palpi of available specimens are notably short and robust; 

 the parraa is subr octangular; in H. dromedarii it is typically tri- 

 angular. The most notable distinction between the two species is
