Frequent Presence

Three new species of Fossombronia from Northern Province, Gauteng and Mpumalanga (formerly Transvaal) are described: F.  gemmifera, F. glenii and F. straussiana. F. gemmifera is distinguished by a highly convoluted pseudoperianth, the frequent presence of gemmae produced dorsally on the stem, lamellate spores and mostly rather short elaters; F. glenii can be recognized by a smallish, deeply lobed pseudoperianth, perigonial bracts with finger-like projections shielding the antheridia and by spinous spores; F. straussiana is distinct by its hyaline or brownish rhizoids, by its dense, frilly leaves, its pseudoperianth with lamellate lateral outgrowths, by spore ornamentation that usually has inclusions in the incomplete areolae and by the elaters which are finely papillose.

Another three new species of Riccia in section  Pilifer Volk are described from Namaqualand, namely  R. furfuracea, R vitrea and R. namaquensis. There are certainly more undescribed species present in that region, but species from there are often very difficult to distinguish: almost all have hyaline scales, the free-standing dorsal cell pillars need to be examined in living plants and the spore ornamentation is quite variable.

Dorsal Cells

Species in section Pilifer Volk (1983) are often very difficult to identify (Perold 1990b). Most of them require close examination of the dorsal cell pillars in reasonably fresh collections, as these cells can seldom be reconstituted in long dried material.The three species,  R elongata.  R ampullacea and R trachyglossum, here described as new, have been maintained in cultures for lengthy periods, during which their dorsal cells were studied. The spore ornamentation was also quite useful in separating these species.  R elongata is known from eastern Transvaal,  R. ampullacea from the Witteberg Mountains of the eastern Cape Province and the Drakensberg Mountains of Lesotho and Natal, and R. trachyglossum is so far known only from (he highlands of Lesotho.

Three New Species

Field studies of the sub-Saharan African and largely southern African Hesperantha conducted since 2003 have resulted in the discovery of three new species in this genus, bringing the total to 82. Hesperantha longistyla J.C.Manning Goldblatt. known from one collection from the mountains of SW Namibia, is a dwarf plant with moderately long-tubed, purple flowers and unusually long style branches, possibly allied to the Kamiesberg species,  H. latifolia. A second species,  H. helmei Goldblatt J.C.Manning, also known from a single collection from the interior mountains of Eastern Cape near Graaff- Reinet, has terete leaves and small flowers with tepals ± 8 x 2.5 mm, about as long as the perianth tube. It is apparently most closely allied to the Roggeveld species, H. cliolata. A third novelty, H. lithicola J.C.Manning Goldblatt. restricted to the Swartruggens range in the eastern Cold Bokkeveld, has bell-shaped corms with toothed margins, leaves 1-2 mm wide, and white flowers with a tube 10-12 mm long, and appears most closely allied to the widespread H. falcata. A new collection of H karooica from northeast of the Hantamsberg represents a small but significant range extension for this local endemic previously known from just two collections near Calvinia, south of these mountains. The flower size, especially dimensions of the tepals, confirms its status as a separate species allied to H. vaginata. Lastly, new collections o f the relatively uncommon, yellow-flowered variant of H. acuta show that this plant, confined to the eastem portion of the range of the species, differs consistently from the white-flowered form in several floral features, and it is raised to subspecies rank as H. acuta subsp.  tugwelliae.

Three New Species

Although Africa and Indonesia have not been particularly well surveyed for Mycosphaerella leaf spot fungi, several species are known to occur on Eucalyptus leaves in these areas. Three new species of Mycosphaerella with anamorph states are described from herbarium specimens and cultures in the present study. Mycosphaerella suttoniae and Mycosphaerella heimioides are described from Eucalyptus leaves from Indonesia. The former species is of particular interest, because its anamorph Phaeophleospora epicoccoides is the first species of Phaeophleospora linked to Mycosphaerella. Mycosphaerella irregulariramosa is described from Eucalyptus saligna growing in the Northern Province of South Africa. Both M. irregulariramosa and M. heimioides have Pseudocercospora anamorphs, and these are described as Pseudocercospora irregulariramosa and Pseudocercospora heimioides. Notes are also provided on the host range and geographic distribution of previously described species of Mycosphaerella on Eucalyptus leaves in other parts of Africa and in Indonesia. Key words: Eucalyptus, Kirramyces, Mycosphaerella, Phaeophleospora, Pseudocercospora, systematics.

The Lecithoceridae of southern Africa are reviewed, based on material preserved in the Ditsong National Museum of Natural History, Pretoria, Republic of South Africa. A total of 22 species are recognized including three new species: Idiopteryx jansei sp. nov., Lecithocera minyodes sp. nov. and Protolychnis natalensis sp. nov. Isotypa Janse, 1954 syn. nov. is synonymized with Idiopteryx Walsingham, 1891 and Homaloxestis lophophora Janse, 1954 stat. rev. is raised to species rank, separating it from H. cholopis Meyrick, 1906. In addition, Lecithocera ochrometra Meyrick, 1933 is transferred to Torodora Meyrick, 1894 as T. ochrometra (Meyrick, 1933) comb. nov., Lecithocera officialis Meyrick, 1911 is excluded from Lecithocera Herrich-Schäffer, 1853, and Dragmatucha proaula (Meyrick, 1908) is newly reported from Kenya. It is revealed that the male genital figure for Homaloxestis cholopis (Meyrick, 1906) by Janse (1954) was erroneously illustrated, based on a different species which is probably undescribed. Another miss-placed figure of the genitalia by Janse (1954) was also found for Lecithocera aenicta Janse, 1954. Diagnosis, descriptions (only for the new species), depositories of types, and distribution data of all the known species are provided. Images of adults, male and/or female genitalia, and the venation of a few species are illustrated.

Three New Species

The genus Ranops Jocqué, 1991 was only known from three species so far. Three new species of the genus are described here: R. robinae sp. nov. (♂♀) from South Africa, R. tharinae sp. nov. (♂♀) from Botswana, and R. wandae sp. nov. (♂♀) from Namibia. Its distribution is discussed and a distribution map for all the Ranops species is provided. Ranops expers (O.P. Cambridge, 1876) does not belong to Ranops and is transferred back to Zodarion Walckenaer, 1826.
