Revision of Lycoseris (Compositae-Mutisieae)

The genus Lycoseris is revised to include eleven species of dioecious subshrubs with mostly scrambling branches. It is distributed from Guatemala to northwestern and western South America, reaching south to Bolivia and southern Brazil. Three new species are described, viz. L. colombiana, L. minor , and L. peruviana. One new combination is made, viz. L. trinervis ssp. altissima.     

Revision of Comesomatidae (Nematoda)

The gross and fine morphology of the family Comesomatidae is reviewed and the systematic position of its members revised. Significant differentiating characters of the Comesomatidae within the Chromadorida are: a copulatory apparatus provided with apophyses, a female reproductive system with outstretched ovaries, the presence of marginal tubes within the oesophagus, and a non-sclerotized and enlarged tail tip. For classification within the family the following three main characters are used: the structure of the buccal cavity, the structure of the copulatory apparatus, and the arrangement of the cephalic sense organs. Structure of the Sabatieria type is considered basic. The genera are rearranged in three subfamilies as follows: Sabatieriinae ( Cervonema, Laimelia, Pierrickia, Sabatieria (syn. Actarjania), Scholpaniella ), Dorylaimopsinae (Dorylaimopsis (syn. Mesonchium), Hopperia, Metasabatieria, Paramesonchium, Vasostoma ), Comesomatinae ( Comesoma, Metacomesoma, Paracomesoma. ) Six species of Comesomatidae are described from the øresund, Denmark: Cervonema macramphis sp.n.; Laimelia filipjevi nom. nov. (syn. Sabatieria longicaudata Filipjev, 1922); Sabatieria hilarula De Man, 1922; S. ornata (Ditlevsen, 1918); S. punctata (Kreis, 1924); Dorylaimopsis punctata Ditlevsen, 1918. Representatives of these species constitute more than 40% of the total number of nematodes in the region.     

Revision of Reldia (Gesneriaceae)

Reldia (Gesneriaceae) includes terrestrial herbs with alternate leaves, inflorescences which often possess both primary and secondary pedicels but are epedunculate, small white, spurred flowers, a nectary usually reduced to a dorsal gland, and a bivalved capsule. The genus is distributed from Panama to northern Peru. In the present work five species are recognized: Reldia alternifolia from Panama; R. minutiflora , originally described from Peru, but distributed from this country north to Panama; two new species from eastern Ecuador, R. calcarata and R. multiflora , and one new species from Colombia, R. grandiflora . Two varieties of R. minutiflora are recognized, var. minutiflora and var. veraguensis. Reldia occurs in forested, deeply shaded and highly humid ravines usually along streams. The altitude ranges from sea level up to 2500 meters.     

Revision of Koinocystididae (Turbellaria)

The revision deals with the anatomy and systematics of the known 38 species of Koinocystididae. The taxonomy within the family is revised, a key for the identification of live specimens is given and an attempt is made to reconstruct the phylogeny of genera and species on the basis of anatomical transformation series. New genera are Axiutelga. Brunetia, Getula. Groveia, Itaipusina, Legula ana Neoutelga. New species are Groveia unicornis, Itaipusa bispina, I. curvicirra, Neoutelga inermis, Rhinolasius dillonicus and Utelga pseudoheinckei from the N. American Pacific coast (the latter species also from European coasts) and Itaipusina graefei from the Elbe estuary. Acrumena massiliensis Brunet is transferred from Koinocystididae to Acrumenidae fam.n. Four species are considered to be species incertae sedis.     

Revision of Disepalum (Annonaceae)

The relationship between the Asian generaDisepalum Hook. f. andEnicosanthellum Ban (Annonaceae) is examined in a revisionary study. Despite the disparate perianth morphologies of the two genera, other characters support inclusion of all species in a single genus with nine species. The monocarp stalks in all species are found to be derived from the receptacle rather than the ovary, and are thus not homologous with those found in most other Annonanceae genera. Cladistic analysis indicates that the species on the mainland of Asia and of montane habitats are more primitive than the species of the lowlands and of Sumatra and Borneo. Two new combinations,Disepalum petelotii andD. plagioneurum, are necessary as a result of merging the two genera, and one species,D. aciculare, is described as new.
