Taxonomic Studies in Foliicolous Species of the Genus Porina I. The Porina rufula Aggregate

An analysis of character variation in species of the Porina rufula aggregate, i.e. P. rufula (Kremp.) Vain., P. limbulata (Kremp.) Vain., P. rubentior (Stirt.) Müll. Arg., and P. pseudofulvella Sérus., showed that the hitherto applied concepts of species delimitation - based on perithecial size and colour - are not appropriate and should be replaced by a concept which primarily regards perithecial colour and shape as specific characters. Revision of type specimens proved the identity of P. rufula and P. pseudofulvella, whereas P. limbulata sensu Santesson had to be split into P. limbulata s. str. and P. leptospermoides Müll. Arg. Evolutionary tendencies are seen in reduction of thallus morphology and perithecial pigments as an adaptation to shady habitats, indicating P. leptospermoides as a more primitive and P. rufula as a more advanced taxon. Judging from species distribution, the phylogenetic origin of the P. rufula aggregate might be in the Neotropics.

Some new taxa of desmids from the Andaman Islands,India

Two new species, five new varieties and five new forms belonging to the desmid genera Closterium Nitzsch, Pleurotaenium Naeg., Euastridium W. & W., Micrasterias Agardh, Cosmarium Corda and Staurastrum Meyen from the Andaman Islands are described.     

Kinorhynchs from the Andaman Islands

Echinoderes andamanensis sp. nov. is described from the Andaman Islands (Bay of Bengal, Indian Ocean). Unlike most members of this genus, this new species lacks middorsal spines. It is further distinguished by the presence of lateral spines on segments 4, 10 and 11 in the female and 4, 10–12 in the inale. Collected with E. andamanensis were specimens of E. ehlersi previously known only from a single specimen collected in 1885 in Zanzibar. The Andaman Island females have shorter spines than the males. Additional species include Catena gerlachi , previously known only from Walcair, India. A single juvenile exuvium of Pynophyes sp. was also found. The taxonomic relationships of the species and other members of the genus are discussed.     

A new genus and species of arboreal toad with phytotelmonous larvae,from the Andaman Islands,India (Lissamphibia,Anura, Bufonidae)

A new bufonid amphibian, belonging to a new monotypic genus, is described from the Andaman Islands, in the Bay of Bengal, Republic of India, based on unique external morphological and skeletal characters which are compared with those of known Oriental and other relevant bufonid genera. Blythophryne gen. n. is distinguished from other bufonid genera by its small adult size (mean SVL 24.02 mm), the presence of six presacral vertebrae, an absence of coccygeal expansions, presence of an elongated pair of parotoid glands, expanded discs at digit tips and phytotelmonous tadpoles that lack oral denticles. The taxonomic and phylogenetic position of the new taxon (that we named as Blythophryne beryet gen. et sp. n.) was ascertained by comparing its 12S and 16S partial genes with those of Oriental and other relevant bufonid lineages. Resulting molecular phylogeny supports the erection of a novel monotypic genus for this lineage from the Andaman Islands of India.     

Garcinìa dhanìkharíensis (Clusiaceae), a new species from Andaman Islands, India

A new species Garcinia dhanìkharíensis (Clusiaceae) from South Andaman, India is described and illustrated.     

Description of Ortheziolamameti tranfagliai new species (Hemiptera,Coccoidea, Ortheziidae) from India

This paper describes a new Ortheziolamameti species from the Oriental region (India), namely Ortheziolamameti tranfagliai Konczné Benedicty, sp. n. The examined material was extracted from forest litter from India, using Berlese funnels. With this new species the genus Ortheziolamameti now includes six species. An identification key and distribution map are provided.     

A new species of Stomatostemma (Periplocaceae) from Mozambique, Africa

VENTER, H.J. T. & FIELD, D. V., 1989. A new species of Stomatostemma (Periplocaceae) from Mozambique, Africa. A new species of Stomatostemma is described from Mozambique. 11 is [he second species distinguished in the genus Stomatostemma N.E. Br., the other being S. monteiroae (Oliv.) N.E. Br., which was also described from Mozambique. The new species is distinguished from.V. monteiroae by being a virgate shrub, by the pendulous terminal branches and inflorescences, by the long and frail peduncles and pedicels and by the long clavate corona lobes.     

A new species of sergestid shrimp,acetes orientalis (Crustacea: Decapoda,Sergestidae) from Goa,Central West Coast of India

Acetes orientalis, a new species of sergestid shrimp belonging to the genus Acetes H. Milne-Edwards collected from the Mandovi estuary, Goa, Central West Coast of India has affinities to most of the Indo-Pacific species. The petasma of the male has resemblance in shape to. A. sibogae, A. vulgaris, A. sibogalis, A. australis, A. erythraeus and Acetes sp. and very much alike in structure to that of A. sibogae. The female genital area has a pair of protuberance as in A. vulgaris and A. indicus. These combinations in characters along with several other important features which justify the creation of this new species are discussed in comparison with those of the other Indo-Pacific species having closet affinities.     

A new species of Festuca L.from Spain

This is the only representative of the genus occurring in the flora of Bangladesh. It resembles P. graeca but may be distinguished by having shorter peduncles, glabrous calyx lobes, hairy coronal scales, broader and horizontally spreading follicles.
