Abstract Orchids constitute an important component of the Pieniny Mts. flora. The presence of 35 orchid species has been noted so far in this region. A considerable number of these species are endangered for various reasons. Eight species have been deemed extinct in the area. On the other hand, the orchid flora of the Pieniny Mts. includes species that widen their local ranges and can, thus, be considered expansive as well as new species, recently entered in the list of orchids occurring in the said mountain range (Epipactis microphylla and Epipactis muelleri). It is necessary and important to conduct an inventory of Pieniny orchid resources (the major aim of this study) that would be repeated at certain intervals, in order to know the number of stations and of individuals per population of each species, which would enable taking relevant actions needed to prevent the disappearance of these plants from the Pieniny Mts.

The so-called ‘Theory of Himalayan Environmental Degradation’ predicted an environmental collapse by the end of last millennium, threatening the life of millions of people. Fortunately, the all-encompassing crisis did not materialize. The article shows that the ‘Theory’ failed to take into account the vast ecological variation in Himalaya and thus generalized its contentions to the whole mountain range on the basis of deficient data. But, on the other hand, what would have happened if the prediction had not been made? A doomsday scenario like the Theory of Himalayan Degradation can, from the perspective of positivist hypothesis testing, be viewed a posteriori as a failed prediction; but from another perspective it can be seen as an alarm clock that triggered a series of policy initiatives and new knowledge.The Geographical Journal of Nepal Vol. 10: 1-14, 2017

Correct Determination

Non-marine Mollusca are extremely rare in the Pliocene deposits of this country, which fact must always be a matter of regret to the Palæontologist, since they are of the utmost importance in connexion with the origin of our present fauna. Unfortunately, in addition to their rarity, they are often decorticated or fragmentary, whence no doubt the differences in opinion as to their correct determination. A re-examination of all the available material has convinced us that there is still much to be done before it will be possible to reach finality. In these matters so much depends on one's standpoint. If one starts with the preconceived idea that the Pliocene shells must be identical with the recent forms, it is easy enough to identify them, even if one has to go to Japan or Greenland to find its present habitat. If, on the other hand, one considers it better to study carefully the results of recent work on other branches of the fauna, it is obvious that different results will be arrived at. Hence we are quite prepared for any differences of opinion as to the correctness of our views or the wisdom of creating four new species, as we now venture to do.

Black ; scape and all legs red testaceous ; ovipositor bright red ; flagellum red-brown, possibly rather darker at apex ; wings hyaline, the setae with a distinctly fulvous tinge, and the stigma hyaline (at least not darkened).♀♂. The integument is not coriaceous throughout, and is only sparsely clothed with setae (except on the flagellum and possibly the legs). Head smooth and highly shining, not coriaceous, impunctate, the vertex and occiput almost entirely devoid of setae ; antennae longer than head, thorax, and abdomen together ; flagellar joints in ♀ 29–33, in ♂ 26–28. Thorax : mesonotum dully shining, coriaceous ; the notauli well marked, joining slightly before reaching the posterior margin of the mesonotum ; propodeon with five longitudinal carinae, one in the middle and two on each side, these latter rather more closely placed to each other than to the median carina ; this median carina is discernible as such only in the basal half of the propodeon, thereafter becoming lost amongst the reticulate wrinkles with which the apical half of the propodeon abounds ; the lateral carinae, on the other hand, are discernible more or less throughout their length, particularly the inner pair which can generally be traced to the median apex of the propodeon where they join each other ; the integument of the basal half of the propodeon coriaceous on each side of the median carina as far as the first lateral carina, thereafter wrinkled as in the apical half.

A New Species

We describe a new species of a large eleutherodactyline frog from the mountain rocky meadows (“campos rupestres”) of the Serra do Sincorá, Espinhaço mountain range, Mucugê municipality, State of Bahia, Brazil. The new species is promptly diagnosed from all the other Brazilian eleutherodactylines by its large size (males SVL 40.3–41.1; females SVL 75.2–79.7mm), broad head (head width 43–49% of SVL), presence of frontoparietal crests, pars fascialis of the maxilla deepened, discs absent on fingers, toes with poorly developed discs, first and second toes ridged, and tarsal fold absent. On the basis of these characters the new species is attributed to the genus Strabomantis up to now restricted to southern part of Central America and northwest part of South America.

Rivers And Reservoirs

A new species of Encyonema was found in several rivers and reservoirs in Western Pennsylvania, USA, in 2013. The new species, E. appalachianum, has only very slightly dorsiventral valves, which is one of the characters separating the genus Encyonopsis from Encyonema. On the other hand, the long, sharply bent terminal raphe fissures and lateral raphe indicate that it should be placed in Encyonema. Some valves with occasionally biseriate striae have been observed in the type population of the new species. The finding of this species that apparently combines features of both Encyonema and Encyonopsis highlights the problem of poorly defined boundaries between some genera of cymbelloid diatoms.

A New Species

The identification of species of Rhipicephalus is likely to give more trouble than is the case with any other genus of Ixodidae, for while, on the one hand, there are few species which depart greatly from the general type, on the other hand the range of variation within the species is extremely great. In no genus is it so dangerous to describe a new species from a single individual, especially if the specimen be a female.

Thirty-one new species of giant pill-millipedes (order Sphaerotheriida) endemic to Madagascar are described: Zoosphaerium haackeri n. sp., Z. album n. sp., Z. discolor n. sp., Z. mitoho n. sp., Z. pulchellum n. sp., Z. endemicum n. sp., Z. xerophilum n. sp., Z. aureum n. sp., Z. pseudopriapus n. sp., Z. pseudoplatylabum n. sp., Z. solitarium n. sp., Z. tsingy n. sp., Z. corystoides n. sp., Z. broelemanni n. sp., Z. amabile n. sp., Z. trichordum n. sp., Z. smaragdinum n. sp., Z. ambrense n. sp., Z. isalo n. sp., Z. bilobum n. sp., Z. tampolo n. sp., Z. ignotum n. sp., Z. tainkintana n. sp., Z. viridissimum n. sp., Z. denticulatum n. sp., Z. pseudoblandum n. sp., Z. micropiligerum n. sp., Z. pseudopiligerum n. sp., Z. analavelona n. sp. and Z. fisheri n. sp., and Microsphaerotherium anjozorobe n. sp.. Twenty-eight of the Zoosphaerium species already fit into established species-groups. A key to all 55 recognizable Malagasy Sphaerotheriida species is given. Forty-two of the 55 giant pill-millipede species are ecosystem endemics, while 26 are geographically microendemic. The number of microendemic species is disproportionately distributed among Malagasy ecosystems. All 13 species restricted to the montane rainforest as well as all five species restricted to the Eastern littoral forest are microendemic. On the other hand, only two out of seven dry forest species, one out of seven rainforest species and one out of five spiny forest species are microendemics. A special emphasis is placed on two species endemic to the unique Western rainforest site of Analavelona, which is currently not protected.

Or Groups

Any two biologic groups — populations, species, or groups of species — that are separated in time but connected by evolution provide us with the opportunity to measure a rate of evolution.Rates are interesting because they vary greatly. Some species have survived for millions of years without appreciable change. On the other hand, some species have arisen from other, quite different species within just a few thousands or tens of thousands of years: very brief intervals of time. Similarly, some groups of organisms have diversified rapidly, producing many new species during brief intervals of geologic time, whereas others have added new species very slowly.

Two new shrubby species of Clusia sect. Cordylandra are described and illustrated. The male flower of Clusia nogueirae presents an androecium forming a conical volcano-like synandrium around a well-developed pistillode covered with resin. The male flower of Clusia ibiapabensis, on the other hand, presents an androecium of free claviform stamens, forming a broad torus-like structure around a well-developed pistillode. The two species occur in regions of brejos de altitude in the plateou of Ibiapaba, Ceará state, northeastern Brazil.

Canthyporus reebae sp. nov. is described from the south-eastern part of the Itremo mountain range and from the Andringitra massif in central eastern Madagascar. The new species is the second one of the genus Canthyporus Zimmermann, 1919 to be recorded from Madagascar, the other being C. pauliani Guignot, 1951, so far endemic to the northern massif of Tsaratanana. The habitus and male and female reproductive structures of the new species are illustrated. Canthyporus reebae sp. nov. differs from C. pauliani notably by larger size, less parallel-sided and more evenly convex habitus, paler pronotum, more weakly impressed body surface reticulation, and a different shape of the median lobe of aedeagus. Differences with similar C. hottentottus-group species from mainland Africa are also discussed. Data on habitat preferences of C. reebae sp. nov. and a distribution map of Malagasy Canthyporus are presented and discussed.
