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 & Fernando, 1981) comb. nov. is here proposed.

A New Species

To date the genus Diploplastron comprised only one species of ophryoscolecid ciliate, Diploplastron affine, which is characterized by having two retractable ciliary zones in the anterior end of the body, two slender and juxtaposed skeletal plates on the right side, a rod shape macronucleus, and two contractile vacuoles. During study on the characterization of rumen ciliate community composition in Brazilian domestic sheep, we observed ciliates with atypical morphology but with diagnostic features of genus Diploplastron. This study describes Diploplastron dehorityi, a new species of ophryoscolecid ciliate, that differs from D. affine, primarily, in the morphology of skeletal plates, morphology of nuclear apparatus and body shape. In addition to the similarities between the new species and congener species, D. dehorityi has some morphological similarities to species of genus Eremoplastron.

A new genus, Dentocypria n. gen., in the subfamily Cyclocypridinae Kaufmann, 1900 is described from Thailand. The main distinguishing characters of the new genus are the presence of an internal tooth on the antero-ventral part of the left valve, the marginal tubercles on the right valve, the very elongated terminal segment of the madibular palp, the absence of setae on the basal segment of the second thoracopod (T2), the unusually long e-seta of T2, the short terminal segment of the third thoracopod (T3), the long Sp seta of the caudal ramus and the morphology of prehensile palps and hemipenis. Four new species of the new genus are here described: Dentocypria mesquitai n. gen. n. sp., Dentocypria chantaranothaii n. gen. n. sp., Dentocypria smithi n. gen. n. sp. and Dentocypria aequiloba n. gen. n. sp. A brief discussion on the generic characters and a key to the genera of the subfamily are provided.

AbstractA new species of the genus Diomedenema, a spiruromorph nematode, collected from the lung of Spheniscus magellanicus (Sphenisciformes) found on the southern coast of the state of Rio Grande do Sul, Brazil, is described. The new species is differentiated from the only previously described species of the genus, D. diomedeae Johston & Mawson, 1952, by males possessing a set of caudal papillae with three pairs of precloacal, two pairs of adcloacal and one pair of postcloacal papillae; precloacal papillae with the papillae of the first two pairs being closer to each other than those of the third pair; a longer and pointed tail in males; and females with the vulva at mid-body. This is the first report of a nematode infecting the lung of a sphenisciforme host.

A new species of calanoid copepod, Centropages aegypticus sp. nov. collected from the Egyptian coasts of the northern Red Sea is described. This species is unique in having two pointed conical processes on the dorsal surface of cephalosome in both sexes, female genital compound somite with irregular-surface outline of the right swelling part and transverse dorsolateral row of spinules on the left side, 2-segmented exopod of the female leg 5, asymmetrical medial processes of the female leg 5, of which the left one is longer and medially-curved and the right one with oblique row of thick spinules, and a club-shaped medial seta on the third exopodal segment of the male leg 5. The new species is similar to C. tenuiremis, but is not assigned to the same species group as the latter species or to any other groups.

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.

The Oriental genus Andreimyrme Lelej, 1995 is newly reported from India. A new species A. paniya sp. nov. is described based on a female specimen from Kerala part of Western Ghats. Diagnostic features of this new species to separate it from similar species A. neaera (Mickel, 1935) and A. sarawakensis Lelej, 1996 are discussed. This new species has the mesosoma and metasoma with reddish-brown cuticle which approximates Eastern mimicry ring in North America. Andreimyrme paniya sp. nov. expresses a rare color pattern. In India such color syndromes occur in two species of the tribe Smicromyrmini and two species of the subfamily Dasylabrinae. These species inhabit the tropical moist broadleaf forest ecoregion of southern India. An updated diagnosis for males and females of Andreimyrme is given.

The key presents all 59 species of the genus Trichocera Meigen which occur in Europe. Four subgenera are represented: Trichocera Meigen 1803 (five species), Metatrichocera Dahl 1967 (seven species), Saltrichocera Krzemińska 2002 (35 species), and Staryia Krzemińska & Gorzka 2016 (13 species). The type material of two species, one from North America and one from Asia, are described (Trichocera columbiana Alexander, 1927 and T. arctica Lundström, 1915), whose identities cause some problems and whose presence in the northern regions of Europe is possible. Two new species are described, Trichocera (Saltrichocera) longa, n. sp., and T. (Staryia) oulankae, n. sp. Trichocera versicolor is resurrected from synonymy; T. limpidipennis is synonymized with T. regelationis. There are separate keys to males and females; species are illustrated with camera pictures of diagnostic features: genitalia, antennae, and male tarsal claws, and additionally, wings and thoraces when only one sex is known, to enable further search. The state of knowledge of the genus in Europe and in the world is discussed.

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.

The enchytraeid fauna of three areas in Jeju Island (Korea) was studied, and comparative morphological and molecular taxonomic examinations (based on CO1, ITS and H3 sequences) were performed on nine samples collected in 2016. Twenty-two enchytraeid species were recorded and identified. The descriptions of two new species (Achaetamultisacculatasp. n.andFridericiafloriformissp. n.) are presented in this paper. The main diagnostic features ofA.multisacculatasp. n.are: three pairs of pyriform glands per segment, clitellum with two “baguette-like” packages of glands, dorsal blood vessel from VII, secondary pharyngeal glands absent, oesophageal appendages well developed, two pairs of preclitellar nephridia, the reproductive organs (except the spermathecae in V) shifted one segment forward. The main features ofF.floriformissp. n.are that they are large worms, have up to 2–4 chaetae in bundles, strong body wall, thick cuticle, five pairs of preclitellar nephridia, c-type coelomo-mucocytes sometimes with some refractile vesicles, chylus cells in XII–XV, sperm funnels approximately twice as long than wide, spermathecae with long ectal duct without glands, ampullae surrounded distally by about 9–12 sessile diverticula of varying size. Molecular phylogenetic analyses supported the morphological results and confirmed the status of the two new species.
