NOTE: The known distribution of this species in Arabia on the map of the American Geographical Society (1954) should be limited to the mountains of the Yemen.

MISCELLANEOUS: Tonelli_Rondelli (1938) noted that Stella (l938D) had reported R. simus from ITALY and indicated that this report is certainly 55 error in identification; also that this species is absent from LIBYA /_reported as present by Stella (19380) 7, ALGERIA, TUNISIA, and Moaocco. Records for Mytilene, GREEDE'(Senevet 1920), repeated without further substantiation by Pandazis (1947), and records for TURKEY (Stefko 1917) are probably also erroneous or refer to introduced, non.established specimens.


Neumann (1911) listed R. simus from EGYPT and Brumpt (1920) stated that East Coast fever exists in Egypt and might be carried by this tick. Mason (l922B) quoted this as an erroneous statement that R. simus occured in Egypt, to which Brumpt (1923, p. 43, footn3te) replied that he had merely hypothesized this possibility on the basis of Neumann's record. Carpano (1936) reported microorganisms in specimens of this tick (?imported or misidentified HR) collected from carnivores in the Cairo zoological gardens. Actually, the glossy tick is not established in Egypt, as con. firmed earlier by Mason (l922B).

Records from TURKESTAN (Yakimov and Kbhl_Yakimov 1911, Yakimov l9l7,l922,l923) are based on material now considered as subspecies of R. sanguineus (cf. page 717). The "R. simus or R. sanguineus" from tortoises in IRAN Cfiichael 1899) probably refers to §.


Data from BORNEO (Neumann 1901) probably refers to R. sanguineus subsp. or to R. haemaphysaloides subsp.

Christophers (l907C) reported R. simus from southern INDIA but, as Sharif (1928) says, this to3 is probably a misidentifica. tion. Patton's (1910) remarks concerning the transmission of Piro lasma _ibsoni of India by a new species of tick related to fii'§§5fi§‘Ea§E'BEEfi elaborated in subsequent reviews to indicate

that E. simus transmits this organism.



Adult hosts of predilection are carnivores, pigs, buffalo, and crther large or medium size game animals. Antelopes are usually second.choice hosts. Among domestic animals, dogs and pigs fre_ cpmently are preferred. The incidence on cattle varies locally and uwy be either very high or very low even where the glossy tick is common. People are frequently attacked, especiall in the vicinity of their dwellings. Although Matthysse (1954 con. siders adults to be parasites of medium size mammals, overall data indicate that host size is only one factor, the type of host being an equally important consideration. Larvae and nymphs feed chiefly on burrowing rodents, less commonly on other small animals.


Cattle: Factors influencing parasitism of domestic cattle by R. s. simus are still unknown. Although this tick is common

thraughout Eauatoria Province, its incidence on cattle is nil or low everywhere except in Juba District where the rate may run

fairly high. In Central Sudan, the numbers on cattle are variable but never high.

R. s. simus is one of the five species of this genus that

occurs with any degree of frequency on Uganda cattle but in most districts the rate of infestation is low (Wilson 19500).


In South Africa, the glossy tick “does not appear to thrive

well on cattle" (Lounsbury 1904B). Theiler (correspondence), however, reports that in cattle raising areas of South Africa these animals are the favorite host of the glossy tick.

Wilson (l950B) considered this to be an uncommon Nyasaland tick because he took it on only 24 occasions during an extensive three year tick surv . Ten of these collections were from cattle. Ehrlier, Wilson (1942) doubted that females ever become fully engorged on cattle. Theiler (correspondence) has found that the glossy tick is more common in Nyasaland than Wilson believed. Rarity of cattle infestation here probably accounts for this discrepancy inasmuch as relatively few wild animals were examined. Matthysse (1954) considers this to be a rather important Northern

Rhodesian cattle parasite, but does not provide a clear cut anal. ysis of the situation there.

Low incidence of E. E. simus on cattle is not universal. It is not only common but numerous on cattle on the coastal plains of Kenya (Dick and Lewis 1947).

Dogs: Throughout the range of E. 3. simus, domestic dogs are frequently among its most common hosts and are mentioned by many authors. In Equatoria Province, dogs are infested by this parasite as frequently as they are by R. s. san~ 'neus, but the numbers of simus are considerably lower ii all collections except those from Kajo Kaji. The yellow dog_tick, H. l. leachii, is much less common on dogs in the Sudan but in certain other areas of Africa this is one of their most in rtant arthropod parasites. Kauntze (1934) and Roberts (1935 did not consider R. s. simus to be an important pest of dogs when studying bouton_ '3eu3e'TE¥§¥ in Kenya, but Dick and Lewis (1947) found this common tick to be only slightly less numerous on dogs than R. s. san~ 'neus in the coastal area of Kenya. At Nelspruit, South-Afr ca, Lounsbury (l904A) collected more glossy ticks than kennel ticks on canines in the same place. According to Theiler (correspondence), R. s. simus and H. 1. leachii generally are more common on South Ifrlcan dogs than 15 R. s. san'uineus, and H. l. leachii is usually the most common of-the three. Matthyssé-(I954) listed.§. E. simus only once from Northern Rhodesian dogs, and noted R. a en. diculatus, §. §. sanguineus, and E. tricuspis more frequent y.

Pi s: Wherever I have encountered domestic pigs in the range of the g ossy tick, a close association between the two and a high rate of infestation has been noted. No mention of similar situations is found in the literature. Wild warthogs and bushpigs (see below) are commonly infested. In South Africa, on the other hand, domestic pigs are amazingly free of ticks and more are recorded from bushpigs than from warthogs (Theiler, correspondence).

Tendeiro's reports from Portugese Guinea (listed above) contain numerous references to E. E. simus and E. E. sene alensis on domes. tic pigs. The identity of West Ifrican specimens should be checked.

Other domestic animals are more or less frequently reported as

hosts, but the incidence is seldom if ever mentioned. In addition to the Sudan records given above, some of these are:
