This article is devoted to a review of specimens identified as belonging to the genus Maraenobiotus Mrázek, 1893 reported for Bulgaria from the Rhodope and Rila Mountains under the name of Maraenobiotus vejdovskyi truncatus Gurney, 1932. Closer examination of the armature of the caudal rami and other morphological characteristics revealed significant differences between the specimens from these disjunctive populations and M. truncatus that had been originally described by Gurney (1932) from the United Kingdom. Based on these differences, the population from the Western Rhodope Mountains is described here as a new species, M. rhodopensis n. sp., and the population from the Rila Mountains is described here as M. rilaensis n. sp.

In the autumn of last year Sir Archibald Geikie, F.R.S., Director-General of the Geological Survey of the United Kingdom, Kindly placed in my hands for determination a number of specimens of Cephalaspis, collected by his officers in the Lower Old Red Sandstone of the neighbourhood of Oban. On examining them, I found that they all belonged to one species, which was, however, new to science.Accordingly I drew up a brief diagnosis of this new form, which was included by Sir Archibald in his Summary of Progress of the Geological Survey for 1897, and it is now my privilege, with his sanction, to offer to this Society a more detailed description of the species, accompanied with figures.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Leptochelia Vatulelensis(Crustacea: Tanaidacea), A New Species From Anchialine Caves of the South-Western PacificLeptochelia vatulelensisn. sp., discovered on the small islands of Vatulele (Fijian group) and Ouvéa (Loyalty Islands, New Caledonia), is described and illustrated. The new species is distinguished from the others of the"Leptochelia-dubiagroup" (to which it is generally similar) by the following combination of morphological characteristics: (1) the presence of three to four distal setae on the maxilliped basis; (2) merus of pereopods III and IV with only a distosternal seta; (3) endopod of the uropods formed of four (rarely three) articles; (4) males with two (sometimes three) relatively short aesthetascs on the first five articles of the antennular flagellum; (5) male cheliped with a diminished dimorphism; (6) males with a vertical comb-row of setae on the cheliped propodus. Although it inhabits inland, anchialine caves, the new species lacks morphological features that are characteristic of some cave species.

Two New Species

Two new species of the ant genus Myrmecina Curtis, 1829 are described and illustrated based on the worker and queen castes collected in Sumatra, Indonesia under the names M. andalas sp. nov. and M. nitidiuscula sp. nov. Each species displays unique morphological characteristics. Myrmecina andalas sp. nov. is characterized by a combination of the following characteristics: head dorsally sculptured, with the ventrolateral area smooth and shiny; propodeal spine short, triangular, pointing dorsad and with a broad base; propodeal declivity vertical, with the posterodorsal angle almost 90°. Myrmecina nitidiuscula sp. nov. is characterized by a combination of the following characteristics: head dorsum largely smooth and shiny; propodeal spine triangular and pointing posteriad, with a very broad base. Updated key to Myrmecina species of Sumatra is given.

A New Species

The Chorthippus biguttulus group distributed in the west Palaearctic, while intensively examined in Europe, is poorly known in the glacial refugia such as Anatolia. This produces constraints in making accurate statements about evolution and the biogeography of the group. The C. brunneus subgroup of this lineage is examined using large amounts of morphological and song data from Anatolia (Asian Turkey) and representatives from Europe. Song and morphology in combination suggested three species to be found in Anatolia. The first is C. bornhalmi Harz which is also known from south-east Europe. The other two are new species: Chorthippus antecessor sp. n. and Chorthippus relicticus sp. n.. Morphologically, C. antecessor sp. n. is the most aberrant species of the C. brunneus subgroup, but is similar to C. bornhalmi in song. The specific song and morphology (the aberrant number of stridulatory pegs) define C. relicticus as a new species and both also indicate that it is closely related to C. brunneus and C. jacobsi. A song and morphology based phyloylogenetic assumption for C. brunneus subgroup suggests C. antecessor, C. bornhalmi and C. miramae to constitute one clade and C. brunneus, C. jacobsi and C. relicticus another. The scenario suggested for their evolution assume the following steps: (i) divergence of C. bornhalmi from a C. antecessor like ancestor, (ii) derivation of an ancestral population (which later give rise to C. brunneus + C. jacobsi + C. relicticus) from a C. bornhalmi like ancestor, and (iii) later fragmentation of this ancestral population to result in the present three species (C. brunneus + C. jacobsi + C. relicticus). All of these events seem to be correlated with the climatic cycles during Pleistocene. The conclusion is that the two new species are range-restricted, vulnerable species as is the case for many other taxa present in the Mediterranean Taurus biodiversity hotspot.
