The Family

Cissus Linnaeus (1753: 117) is the most speciose genus in the family Vitaceae and notable for its pantropical intercontinental disjunct pattern (Liu et al. 2013). According to the recent estimate, the genus is known to have 291 accepted species (POWO 2020) and it is widely distributed in tropical regions of Africa, Asia, Australia, Central and South America and Mexico (Wen 2007). The main characters delimiting Cissus from other Vitaceae genera are the well-developed, thick and undivided floral disks, tetramerous flowers, one-seeded berries, and seeds with a long and linear chalaza (Wen 2007). In South America, Cissus is represented by 64 species (Lombardi 2000, 2007, Rodrigues et al. 2014). Amongst C. ulmifolia (Baker 1871: 213) Planchon (1887: 552) that is a later homonym of an Italian fossil taxon Cissus ulmifolia Massalongo (1858: 80). While checking the literature and relevant websites for the availability of any synonyms, we found that C. allenii Croat (1977: 358) and C. serrulatifolia Williams (1962: 375) are listed as heterotypic synonyms of C. ulmifolia in Tropicos (2020) following Nelson (2010). However, C. allenii was synonymized under C. serrulatifolia by most of the workers (Govaerts 1999, Lombardi 2007, Morales 2015, POWO 2020, Raz & Zamora 2020) but C. ulmifolia was treated as a distinct species. So in order to ascertain the taxonomic status, we critically studied the protologues and digital specimens including types of these three species, we found that the characters of C. allenii are well within the range of C. serrulatifolia but C. ulmifolia differs from them by its 4-sided, distinctly winged stem (vs. stem terete, not winged or wingless in C. serrulatifolia) and the fruits ovoid or ovoid–subglobose, smooth (vs. obovoid or subpyriform, lenticellate in C. serrulatifolia). Since no other validly published legitimate name is available for this species (Lombardi 2007, Mota de Oliveira & Jansen-Jacobs 2016, POWO 2020), therefore, the authors propose Cissus lombardiana as a replacement name.

Marine Gastrotricha, both Macrodasyida and Chaetonotida, are the subject of an analytic review, citing taxonomic status of names, authorships of taxa, and those responsible for changes, in accordance with the International Code of Zoological Nomenclature, 4 th ed. (1999). Notes are included with regard to taxonomic usage so as to guide workers in the future. Among the proposed novelties are: within Macrodasyida, to restrict the family Lepidodasyidae Remane, 1927 to the genus Lepidodasys Remane, 1926, and to establish a new family, Cephalodasyidae with Cephalodasys Remane, 1926 as its type-species to house the remaining genera and species that have been contained in the polyphyletic family Lepidodasyidae. Hemidasys agaso Claparède, 1867 is considered extinct, and the new name Tetranchyroderma antenniphorum is proposed for Tetranchyroderma antennatum Luporini, Magagnini & Tongiorgi, 1973; in addition, five species are here considered to be species inquirendae: Dactylopodola weilli d'Hondt, 1965, Paradasys nipponensis Sudzuki, 1976, Macrodasys indicus Kutty & Nair, 1969. Tetranchyroderma forceps d’Hondt & Balsamo, 2009 and Turbanella plana (Giard, 1904b). Among Chaetonotida: the Xenotrichula velox-species group Ruppert, 1979 and the Xenotrichula intermedia-species group Ruppert, 1979 were given each the rank of subgenus. Chaetonotus pleuracanthus Remane, 1926 is rejected as a synonym for Chaetonotus marinus Giard, 1904; Chaetonotus somniculosus Mock, 1979 is transferred to the genus Halichaetonotus, the new name Halichaetonotus euromarinus is proposed for Halichaetonotus spinosus Mock, 1979, and Xenotrichula carolinensis Ruppert, 1979 is re-established. Heteroxenotrichula variocirrata d'Hondt, 1966 is here considered to be species inquirenda.

Two only partially known species of the family Gammaridae (Crustacea Amphipoda), Gammarus werneri (S. Karaman 1934) and Gammarus paraorientalis G. Kar. (new comb.) are treated. Rivulogammarus kesslerianus werneri ssp. n. has been shortly described by S. Karaman (1934) from Iznik (Asia Minor, NE Turkey) and later considered synonym of Gammarus balcanicus Schäferna 1922 (G. Karaman, 2003).Based on detailed study of holotype and one more recent sample of the same species from Iznik, this species is redescribed, figured and elevated to the species rank, Gammarus werneri (S. Karaman, 1934), belonging to Gammarus balcanicus Complex,Rivulogammarus balcanicus orientalis ssp. n. has been described by S. Karaman (1934) from Derbend [eastern site of Erdschias- dag (=Erciyas-dagi), Asia Minor (Turkey)]. Recently this species was redescribed and figured as distinct species, Gammarus orientalis (S. Karaman, 1934) from type locality and adjacent localities (G. Karaman, 2017). The new study showed that the name Gammarus orientalis is “nomen preoccupatum”, because the species under the same name has been described by Dana (1852) from Sundai, and new name for G. orientalis from Iznik is proposed, Gammarus paraorientalis G. Kar. (new name).

The genus Apobaetis Day is one of the few lineages of the family Baetidae distributed throughout the continental Americas. Three very similar species of this genus—Apobaetis etowah (Traver), Apobaetis signifer Lugo-Ortiz & McCaffety, and Apobaetis fiuzai Salles & Lugo-Ortiz—have important morphological details, pertinent to species identification, that remain to be described. This lack of detailed taxonomic information has resulted in ample misdiagnoses of the species, particularly regarding A. fiuzai in South America. In fact, almost all the recently collected specimens have been assigned to this species. The present study aimed to establish a new morphological diagnosis of these three Apobaetis species through a redescription of their larvae, based on type material, and the proposition of a new identification key for larvae of this genus. The review of the type specimens supports two conclusions: (i) that A. etowah, A. signifer, and A. fiuzai are highly similar, yet can be considered as distinct species, and (ii) the previous diagnoses and keys do not effectively separate A. fiuzai from A. signifer.

Caviomorph Rodents

Subterranean tuco-tucos of the genus Ctenomys are caviomorph rodents comprising a complex of over 50 nominal speciesfound in the southern half of South America. The validity of several nominal forms awaits a proper assessment. Thepopulation of Ctenomys from Ñacuñán Biosphere Reserve (Mendoza, Argentina) has been classically considered torepresent a distinct species and has been commonly referred as Ctenomys “eremofilus”. Based on molecular andcytogenetic analysis we assessed the taxonomic status of the Ctenomys population of Ñacuñán. Specimens analyzedshowed two very similar chromosome complements (2n=48 and 2n=50), the latter being widely distributed in populationsof C. mendocinus. Similarly, haplotypes recovered from Ñacuñán specimens are very similar and sister to those recoveredfrom specimens of C. mendocinus. Considering this evidence we conclude that the individuals of Ctenomys from Ñacuñán population should be assignable to C. mendocinus.

The shell morphology and anatomy of two enigmatic Pisidium species, Pisidium dorbignyi Clessin, 1879, never re-examined after the original description, and Pisidium lebruni Mabille, 1884, a species not reported again until 1995, are described. The type of P. dorbignyi (new name for Cyclas pulchella d´Orbigny, 1835) is lost, for which, and in order to define the taxonomic status of the species, a neotype is herein selected. Both species share as common features: the presence of only the anal siphonal aperture, only one pair of demibranchs, the inner and the type of nephridium, closed with lateral loop visible from dorsal view, consistently differing in shell morphology. Previously unknown details on the anatomy of Pisidium sterkianum Pilsbry, 1897 and Pisidium vile Pilsbry, 1897, particularly those concerning the type of nephridium and inner radial mantle musculature, are described and illustrated for the first time.

The Family

Symplocos Jacquin (1760: 24) is the largest genus in the family Symplocaceae and comprises about ca. 340 species (Fritsch et al. 2008). It is distributed in the tropical and subtropical regions of eastern and southeastern Asia, the Americas and Australia (Nooteboom 2004). The genus Symplocos Jacq. is known to have 33 species in Ecuador (Ståhl 2010; Ulloa et al. 2015), the majority of which occur in Andean forests (Ståhl 1995). While revising the genus Symplocos in Ecuador, Ståhl (1991) described 15 new species. Among these, the name S. globosa B.Ståhl (1991: 27) is illegitimate, being a later homonym (Art. 53.1 of the ICN; McNeill et al. 2012) of the fossil taxon S. globosa R. Ludwig (1857: 98). Therefore, the new name Symplocos ståhlii Kottaim. is proposed here as a replacement name for the extant S. globosa.

New Name

The taxonomic position of two succulent members of the Ruschieae (Aizoaceae), Ruschia stricta var. turgida and R. promontorii, that are currently placed in Amphibolia, is revised on account of new morphological information. Ruschia stricta var. turgida, endemic to the Knersvlakte (Western Cape, South Africa), is characterized by 6-locular fruits, the lack of closing bodies and the lack of filamentous staminodes. Amphibolia has 5-locular fruits with closing bodies and flowers with filamentous staminodes. Consequently, R. stricta var. turgida cannot belong to Amphibolia. On account of differences in the fruits and inflorescences, we recognize R. stricta var. turgida as a distinct species. We show that R. promontorii is different from Amphibolia laevis, of which it has been considered to be a synonym. In particular, these two differ by their ecological preferences and by certain morphological features. In addition, a new name, Ruschia vaginella, is published for the illegitimate Ruschia vaginata.

With additional data from specimens not studied by previous workers, the confusing Simaba guianensis compex was re-analized. Simaba polyphylla is recognized as a distinct species and two subspecies of S. guianensis are maintained. Simaba polyphylla, S. guianensis ssp. guianensis, and S. guianensis ssp. ecaudata are keyed, described, and illustrated and specimens examined are cited for each. Specimens of S. guianensis ssp. ecaudata show great morphological diversity but can be separeted into three groups. Further collecting may provide information that shows these groups to be worthy of separate taxonomic status.

Bryophytes are the second largest group of land plants and are also known as the amphibians of the plant kingdom. 67 species of bryophytes have been reported from select locations across the state of Gujrat. The status of family fissidentaceae which is a large moss family is being presented in this paper. Globally the family consists of 10 genera but only one genus, Fissidens Hedw. has been collected from Gujarat. Fissidens is characterized by a unique leaf structure and shows the presence of three distinct lamina, the dorsal, the ventral and the vaginant lamina. A total of 8 species of Fissidens have been reported from the state based on vegetative characters as no sporophyte stages were collected earlier. Species reported from the neighboring states also showed the absence of sporophytes. The identification of different species was difficult due to substantial overlap in vegetative characters. Hence a detailed study on the diversity of members of Fissidentaceae in Gujarat was carried out between November 2013 and February 2015. In present study 8 distinct species of Fissidens have been collected from different parts of the state. Three species Fissidens splachnobryoides Broth., Fissidens zollingerii Mont. and Fissidens curvato-involutus Dixon. have been identified while the other five are still to be identified. Fissidens zollingerii Mont. and Fissidens xiphoides M. Fleisch., which have been reported as distinct species are actually synonyms according to TROPICOS database. The presence of sexual reproductive structures and sporophytes for several Fissidens species are also being reported for the first time from the state.
