Species of the genus Crotonia (Acari: Cryptostigmata) from New Zealand

Five new species of Crotonia from New Zealand ( C. cervicorna, C. cupulata, C. longibulbula, C. tuberculata and C. reticulata ) are described as new, and two species ( C. cophinana (Michael 1908) and C. caudatis (Hammer 1966)) are redescribed. Five species groups of the genus are characterized and a key to the adequately described species of the world is presented.     

A new pelagic predatory pike cichlid (Teleostei: Cichlidae: Crenicichla) from the C. mandelburgeri species complex with parallel and reticulate evolution

The Crenicichla mandelburgeri species complex from the Middle Paraná shows parallel evolution of ecomorphs to the unrelated C. missioneira species complex from the Uruguay River. In this article, we describe a new species from the C. mandelburgeri species complex that has evolved a parallel morphology and ecology to an unrelated species from the C. missioneira species complex (C. celidochilus). The new species is a pelagic predator that feeds predominantly on fishes and together with C. celidochilus is the only known pelagic species in the large riverine genus Crenicichla. The new species is endemic solely to a small tributary (the Urugua-í) of the Middle Paraná River where it is sympatric and partly syntopic with two other closely related endemic species that, however, differ strongly in their ecomorphologies (one is a generalistic invertivore and the other a specialized molluscivore). Mitochondrial DNA phylogeny finds the new species nested within the widespread C. mandelburgeri. Reduced genome-representation ddRAD analyses, however, demonstrate that this new species is of a hybrid origin and shares ancestry with C. ypo, one of the two studied sympatric species.

     

Chorigyne, a new genus of the Cyclanthaceae from Central America

Chorigyne is described as a new genus, characterized by distichous leaves with bifid lamina, free pistillate flowers, four subapical placentas, and fusiform seeds. It is most closely related to Sphaeradenia and Stelestylis. The generic relationships, and the restricted distribution of Chorigyne in Costa Rica and Panama, are discussed. Five species are described as new, viz. C. densiflora, C. pterophylla, C. paucinervis, C. cylindrica , and C. tumescens. Furthermore, two new combinations are made, viz. C. ensiformis and C. pendula. A key to the species is given, each species is described, and the new ones are illustrated.     

Three new species of Centella series Glabratae (Apiaceae)

Three new species of Centella series Glabratae are described in this paper: C. brachycarpa, C. dolichocarpa and C. pilosa. These species are similar to C. difformis , and in order to clarify species limits the latter is also described and illustrated. The fruit shape and the bulging commissure of the new species show that the sectional limits of the series Glabratae will have to be revised to include C. difformis and related species, previously associated with the series Montanae.     

The genus Chaetomium in Iran, a phylogenetic study including six new species

Twenty-one species of Chaetomium known from Iran were compared on the basis of morphological and molecular characters. Six new species are recognized, five isolated from cereals and one from nematode cysts. A combined sequence dataset of the ITS region, partial LSU rDNA, and β-tubulin gene sufficiently resolved five species groups of Chaetomium that are largely concordant with combined features of peridium structure, ascospore shape and germ pore position. Among the new species C. undulatulum is a close relative of C. globosum, C. rectangulare is close to C. elatum, C. interruptum and C. grande are close to C. megalocarpum, altogether forming the C. globosum species group. Chaetomium iranianum and C. truncatulum are members of the C. carinthiacum species group, characterized by spirally coiled ascomatal hairs and fusiform ascospores. A chrysosporium-like anamorph is newly described for C. acropullum.     

Chromodorid opisthobranch Mollusca from East Africa and the tropical West Pacific

Six species of Hypselodoris and three species of Chromodoris axe described from the coast of East Africa. Three species of Hypselodoris and one species of Chromodoris are new species. Two species of Chromodoris from the tropical West Pacific are also described. The eleven species fall into three groups of similarly coloured species.
Hypselodoris nigrostriata and a new species of Hypselodoris are compared with H. infucata, H. festiva, H. obscura and two unnamed species from the literature. It is concluded that all these are distinct species.
H. nigrolineata and two new species, are compared with H. lineata and H. hilaris and all are considered distinct.
H. regina, Chromodoris quadricolor, C. africana, C. elisabethina, C. magnified and a new species of Chromodoris, are compared with C. westraliensis and two unnamed species from the literature. All these species are considered distinct.
All other names for forms falling into these three colour groups are considered synonyms of one or other of the above named species. Full synonymies are given.     

Crepidomanes malabaricum, a new filmy fern species (Hymenophyllaceae-Pteridophyta) from Southern India

Crepidomanes malabaricum , a new species of filmy fern from South India is described and illustrated. The new species is allied to C. intramarginale and C. christii .

Taxonomic revision of and supplement to the Tectaria Cav. (Aspidiaceae) from Yunnan,China

Tectaria Cav. is a large fern genus of ca. 150 species distributed in the tropic and subtropic regions of the world, of which 27 species and two varieties occur in China. These species are mostly distributed in the southern part to the Yangtze River, mainly concentrated in Yunnan, only two species spreading northwards to Sichuan located in the northern part to the Yangtze River. Based on examination of specimens deposited in KUN and PE, many of which are recent collections, a new species is described, one species and one variety are recognized as new records for China, one species as new record for Yunnan, one species as new record for Guizhou, and four specific names, i. e., T. cosimilis Ching et C. H. Wang, T. decurrenti-alata Ching et C. H. Wang, T. fengii Ching et C. H. Wang, T. simaoensis Ching et C. H. Wang are reduced to synonymies. As a re-suit, 22 species and two varieties are recognized in the genus Tectaria from Yunnan.

The genus Calceolaria in NW South America VII. The section Zygophylla

Sect. Zygophylla of Calceolaria (Scrophulariaceae) in NW South America is revised. It is characterized by connate leaves with winged petioles, and most of the species have intercalary inflorescences. Fourteen species are recognized in the investigated area, one of which is described as new, viz. C. zamorana. Two new combinations are made, viz. C. nevadensis ssp. meridensis (Pennell) Molau and C. purpurascens (Kranzlin) Molau. The chromosome number 2n = 36 is reported for six of the species, viz. C. calycina, C. dilatata, C. grandiflora, C. lanata, C. lojensis , and C. trilobala. The species of sect. Zygophylla are completely interfertile, and sympatric species are isolated by external barriers, e.g. pollination and habitat ecology. Several cases of natural hybridization and introgression are reported.
