A New Species

Two new species of <em>Trechus</em> from the Oromia Province (Ethiopia) are described in the present note. In the first part we describe <em>Archeotrechus</em>, a new microphtalmic <em>Trechus</em>, characterized by the dilation of only the first tarsal segment in males and by the aedeagus with the dorsal part amost completely divided into two lobes: a sclerified connection exists only in the region of the basal ostium. To this subgenus we ascribe the new species <em>Trechus</em> (<em>Archeotrechus</em>) <em>relictus</em>, from the area of Mt. Sgona (Batu), of yellow-brown colour, rather flattened, with non sinuate pronotum and blunt fore and hind angles; two discal setae in the third stria. The aedeagus is much elongated, with a spherical apical button, copulatory piece triangular, lanceolate, with a sharp apex, little sclerified and very simple, typical of ancestral forms, like for instance <em>Minitrechus</em> Vigna Taglianti &amp; Magrini, 2009. The female gonostyli, short and curved, bear at the apex two big setae on the inner edge. In the second part of the note we describe <em>Trechus</em> (s. str.) <em>oromiensis</em>, a new species of <em>bipartitus</em> Group (sensu novo), characterized by the presence of only one discal seta on elytra and by peculiar features of the aedeagus.

In the present note Minitrechus, a new subgenus of <em>Trechus</em>, characterized in the 75 male by only the first tarsal segment dilated and dentate, and by much enlarged paramera, bearing three apical setae, clearly isolated from each other, is described. The new species, <em>Trechus</em> (<em>Minitrechus</em>) <em>gypaeti</em>, is light yellow in colour, rather flattened, with little eyes, pronotum not sinuate, with fore and hind angles blunt; third elytral stria with two discal setae. The median lobe of the aedeagus is short, stout, little arcuate, with a copulatory piece triangular, lanceolate and sharpened at the tip, little sclerified. Female gonostyli short and curved, bear a stout and long ensiform seta on the inner edge, flanked by two smaller ones.

Two new species of Cnemidophorus are described from the right bank of the São Francisco river, in the northwestern part of state of Bahia, Brazil. Both species are assigned to the Cnemidophorus ocellifer group and are distinguished from all other congeners on the basis of lepidosis and color pattern. One of them, Cnemidophorus cyanurus, shares with the species of the subgroup of C. littoralis (C. abaetensis, C. littoralis and C. venetacaudus), a bluish green tail, spurs on the heels of males, 6–7 supraciliaries, a high number of femoral pores (27–45), a row of enlarged scales in the dorsal part of the humerus, and 8 to 10 rows of ventral scales. The second species, Cnemidophorus nigrigula, shares with the C. ocellifer subgroup (composed of C. ocellifer, C. mumbuca, C. jalapensis and C. confusionibus) a low number of femoral pores (14– 21), enlarged scales in the temporal region posterior to the third subocular, 5 supraciliaries, 6 to 8 rows of ventral scales, and a brown tail color. It is also characterized by males being conspicuously larger than females and by females retaining the juvenile color pattern, which is lost in adult males. The latter characteristic has not been reported in any species of the C. ocellifer group before now. The two new species occur sympatrically at Santo Inácio.

A New Species

Mr. A. D. Michael has already recorded* the presence of mites of the genus Tarsonemus upon diseased sugar-cane from Barbados. He states that two species belonging to this genus were present in the material sent to him, and that the larger of the two species was certainly identical with one which Mr. Bancroft found doing serious damage to sugar-cane in Queensland. Mr. Michael proposed the name Tarsonemus bancrofti for this larger species. So far as I am aware, no description of this nominal species has been published and I am obliged to rely on Mr. Bancroft's published sketches† for information concerning it. Unfortunately his drawings are not executed in sufficient detail and I am not certain that his mite is the same species as the one which is dealt with in the present note; but as the figures of the Queensland mite differ appreciably from the Barbados specimens, it seems advisable to describe the latter under another name (T. spinipes). The species of the genus Tarsonemus often resemble one another very closely in structure, and they cannot be recognised with certainty unless a fully detailed account of their principal characters, accompanied by careful drawings, is given. Dr. Bancroft gives drawings of both sexes of his mite. He does not figure any spines on the third leg of the male, but he shows a lobeshaped expansion, similar to that of T. spinipes, on the inner side of the short fourth leg. The hairs of the body are not depicted. According to his drawings, the body of the female resembles that of T. spinipes in being very long and narrow, but is apparently much narrower at the anterior end. He represents the two terminal setae of the fourth leg of the female as being both very long and slender, the outer one being seemingly almost as long as the inner. The size of T. bancrofti is not stated, nor is the scale of enlargement of the figures given.

A New Species

Two new species of the subfamily Cypricercinae McKenzie, 1971 are described from the Western part of Thailand: Pseudostrandesia ratchaburiensis sp. nov. and Strandesia prachuapensis sp. nov. Pseudostrandesia ratchaburiensis sp. nov. is mainly characterized by a flange on the antero-ventral part of the left valve (LV), a markedly large β seta on the mandibular (Md) palp, serrated bristles on the third endite of the maxillula (Mx1), a slender caudal ramus (CR) with a long claw Ga (length ca half that of the ramus) and a relatively low number (13) of spiny whorls in the Zenker’s organ. The discovery of both males and females of Pseudostrandesia ratchaburiensis sp. nov. in the present study constitutes the first report of a sexual population in this genus, thereby allowing for a comparison of the male reproductive organs (hemipenis and Zenker’s organ) from a new species with those of other genera of Cypricercinae. Strandesia prachuapensis sp. nov. is most closely related to Strandesia odiosa (Moniez, 1892) and Strandesia flavescens Klie, 1932 as they bear similar anterior flanges on the right valve (RV). The key diagnostic features of the new Strandesia species are a large carapace (ca 1.5 mm), an angulated antero-ventral part of the LV, a weak and small anterior inner list on the LV, an anterior flange on the RV, a markedly small aesthetasc Y on the second antenna, a large β seta on the Md-palp, smooth bristles on the third endite of the Mx1 and a slender CR with a short claw Ga (length ca ⅓ of the ramus). In addition, Pseudostrandesia complexa (Victor &#38; Fernando, 1981) comb. nov. is here proposed.

A New Species

A new species of <em>Trechus</em> from the Oromia Province (Ethiopia) is described in the present note. This new taxon shows some peculiar characters, such as a much swollen abdomen of pseudophysiogastric aspect, a feature shared by other high altitude Trechinae, as for instance <em>Queinnectrechus</em> Deuve, 1992 from Asia. The integuments are glabrous; the antennae are short; the pronotum is larger than long, with regularly rounded sides and hind angles; the elytrae are short and rounded (pseudophysiogastric) with the first six striae well engraved, on the third of them two discal foveolate setae are well visible. The aedeagus is big and stout, abruptly narrowing at the tip (in lateral view), with a small botton slanting upwards; the copulatory piece is big and well sclerified, triangular, with a more or less sharpened tip. Well recognizable for the “pseudophysiogastric” aspect, <em>Trechus (Trechus) ericalis</em> n.sp. belongs to the <em>bipartitus</em> group.

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.

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.
