Additions to the southern African rust fungi: four new species and two new host genera from South Africa and Angola

AbstractFive Swainson's spurfowl collected in Free State Province, South Africa, were examined for helminth parasites, and the nematodes Acuaria gruveli, Cyrnea parroti, Gongylonema congolense, Subulura dentigera, Subulura suctoria and a new Tetrameres species were recovered. Their respective prevalence was 100, 20, 80, 20, 20 and 20%. These nematodes are all new parasite records for Swainson's spurfowl, and Acuaria gruveli constitutes a new geographical record as well. A single specimen of Cyrnea eurycerca was found in an Orange River francolin, representing a new host and geographical record for this parasite. The new species, for which the name Tetrameres swainsonii is proposed, can be differentiated from its congeners by a combination of the following characters of males: two rows of body spines, a single spicule which is 1152–1392 μm long, and eight pairs of caudal spines arranged in two ventral and two lateral rows of four spines each. The single female has the globular shape typical of the genus.

Trees in the genusVachellia(previouslyAcacia) are commonly infected by the gall-inducing rustsRaveneliamacowanianaandR.evansii. Rust galls bearing aecial infections and relating uredinial and telial infections on the leaves of nineVachelliaspecies not previously recorded to be infected byRaveneliaspp. have recently been collected in South Africa. The rust fungi causing these infections were characterised using molecular phylogenetic analyses of DNA sequence data of the LSU and ITS rDNA regions as well as morphological examinations. The host range ofR.macowanianaandR.evansiiwas thus re-assessed and extended from four to nine species and from one to three species, respectively. Application of Principal Component Analyses (PCA) of telial morphological characters provided evidence of an effect of the host species on the teliospore morphology inR.evansii, but only minor effects inR.macowaniana. A novel gall-inducingRaveneliasp. closely related toR.macowaniana, was found onVachelliaxanthophloeaand it is described here asR.xanthophloeae.

New Host Records

We revised the species of the genus Pristomerus Curtis, 1836 in the Afrotropical Region. Fortynine species are recognized, of which 31 are newly described. The following new species are described: P. afrikaner, P. aka, P. babinga, P. bemba, P. dikidiki, P. herero, P. hutu, P. kagga, P. khoikhoi, P. kuku, P. masai, P. mbaka, P. mbama, P. mboum, P. nzakara, P. protea, P. restio, P. san, P. sara, P. sotho, P. swahili, P. teke, P. tutsi, P. venda, P. wolof, P. xhosa, P. yakoma, P. yangere, P. yoccolo, P. zande and P. zulu spp. nov. New synonyms: P. africator, P. cunctator and P. luteolus are new junior synonyms of P. pallidus. New records: new host records are reported for the widespread P. pallidus; new country-level distribution records are added for P. bullis, P. keyka, P. kelikely and P. pallidus; and reports of Trathala concolor and P. veloma in South Africa are shown to have been erroneous. An illustrated dichotomous key to females is provided; an online Lucid interactive matrix key is also available at www.waspweb.org. Finally, the ecological and geographical correlates of colour patterns exhibited by Pristomerus in the Afrotropical region are discussed.

Tranzschelia Discolor

Up-to-date information is given on the identity, occurrence, nomenclature, host ranges, geographical distribution and literature references of the Urediniomycetes in South Africa. Species of the family Melampsoraceae and all species of the family Pucciniaceae other than those in the genera Puccinia Pers. and Uromyces (Link) Unger are listed. New species records since 1945 include the following: Melampsora allii-populirui Kleb.. Melampsora coleosporioides Dietel. Melampsora laricipopulina Kleb.. Melampsora medusae Thiim., Frommea obtusa-duchesneae (Arthur) Arthur. Hemileia gardeniae-thunbergiae Maubl. Roger. Phakopsora gossypii (Arthur) Hirats. F. Uromycladium tepperianum (Sacc.) McAlpine and Tranzschelia discolor (Fuckel) Tranzschel M.A. Litv. Although many species of rusts have already been recorded, these are thought to represent only a small percentage of the rust population in southern Africa. Furthermore, only a small portion of rust specimens at present housed at PREM have so far been studied. Continued research on this economically important group of fungi is therefore essential.
