Besuchet & I. Löbl) (MHNG). Paratypes: TURKEY: Sinop Prov.: 2 ɗɗ, Lala, near Sinop, 20.V. 1976 (C. Besuchet & I. Löbl) (MHNG). Description. Body length 1.7–1.75 mm. Winged. Body uniformly brown with reddish elytra and yellow legs and palpi. Head sligthly wider (0.31 mm) than long (0.30 mm), frontal rostrum 0.165–0.17 mm wide and 0.06 long, a small tooth in front. Eyes well developed with 20–26 ommatidia. Occipital region slightly convex. Last segment of maxillary palpi 0.2 mm long and 0.08 mm wide. Pronotum wider (0.37–0.385 mm) than long (0.35–0.365 mm) with small and slightly impressed lateral antebasal foveae. Elytra wider (0.685 mm) than long (0.50 mm) with humeri not very protruding. Discal fovea extended posteriorly in large and deep discal stria reaching more than half elytral length. Abdomen with 1 st tergite 0.22–0.235 mm long, basal impression extending more than 1 / 3 of tergite width. Male. Antennae (Fig. 5) 0.75 mm long, club 0.31 mm long; scapus and segment 2 distinctly longer than wide; segment 3 longer than wide and narrowed at base; 4 slightly longer than wide; 5 slightly wider than 4 and slightly longer than wide; 6 wider than long, 7 longer than wide; 8 wider than long and shorter than previous segments. Metaventrite with deep median impression. Legs with femora and tibiae of all legs slightly thickened, posterior margin of mesotrochanters extended into small median spine, mesotibiae with small subapical spur, metatibiae with apical spur. All abdominal sternites not modified. Aedeagus (Figs. 16–17) 0.44 mm long, dorsal apophysis of median lobe sinuate and canaliculate, slightly enlarged at apex, with medial margin prolonged into short spine-like process extended medially and in basal third extendend into short spine. Ventral portion of median lobe slightly shorter than dorsal apophysis, at base relatively large, extended into two spine-like apophyses: the lateral distinctly longer, almost straight, in distal third turned upwards, in basal third of lateral margin with short spine; the medial slightly recurved and directed medially. Female. Unknown. Comparative notes. Tychus spurius sp. n. is similar to T. anser Sabella & Kurbatov, 2002 but distinguished from the latter by the shape of ventral portion and dorsal apophysis of the median lobe of aedeagus. Tychus florentinus species group (Sabella & Poggi, 1997) Note. In the original description of Tychus coiffaiti Besuchet, 1958 the author outlined that this species is similar to T. florentinus Reitter, 1884, T. jonicus Holdhaus, 1908 and T. serbicus Reitter, 1884. All three were placed in the florentinus species group established by Sabella and Poggi (1997), but T. coiffaiti remained unassigned. The discovery of T. grassator, a species very similar to T. coiffaiti, convinced us to include both species in this group of which they present all the diagnostic characters.Published as part of Sabella, Giorgio, Besuchet, Claude & Kurbatov, Sergey A., 2011, New species of Tychini from Turkey and Japan (Coleoptera: Staphylinidae: Pselaphinae), pp. 22-34 in Zootaxa 2764 on page 28, DOI: 10.5281/zenodo.20353

All specimens were collected by sifting litter in oak (<i>Quercus</i>) forests.</p> <p> <b>Comparative notes</b>. The species of <i>Pselaphogenius</i> of the <i>fiorii</i> group have symmetric aedeagi (except <i>P. lucanicus</i> Besuchet, 1964 which shows an aedeagus partially asymmetric with the presence of a ventral lamina), characterized by two evident lateral apophyses of the basal capsule, two well developed and sinuated parameres, one median apical lamina and the armature of internal sac simple consisting of a single piece. Although some of these portions are sometimes recognizable, despite being more or less modified, in the structure of the aedeagus of the other species of the genus <i>Pselaphogenius</i>, they never show the symmetry that characterizes the aedeagi of the species of the <i>Pselaphogenius</i> of <i>fiorii</i> species group.</p> <p> <i>Pselaphogenius chloe</i> <b>sp.</b> <b>n.</b> by the aedeagal and exoskeleton features clearly belongs to the <i>Pselaphogenius fiorii</i> species group, but it is easily distinguished from all the species of this group by some characters of the male and the female. For the head clearly punctate, the reticulated dorsal region of the pronotum, and the elytral lateral fovea slightly larger than medial one, <i>Pselaphogenius chloe</i> <b>sp.</b> <b>n.</b> shows the greatest similarities to <i>P. aspromontanus</i> (Reitter 1910), <i>P. lucanicus</i> Besuchet, 1964 and <i>P. neapolitanus</i> Besuchet, 1964. <i>Pselaphogenius chloe</i> <b>sp.</b> <b>n.</b> is distinguished from the males of these three species by the characters of the aedeagus (cfr. Fig. 1B and Figs 28–33 in Besuchet, 1964), as well as by the secondary sexual characters. The male of <i>P. chloe</i> <b>sp. n.</b> has the metaventrite raised in the middle in a conical process rounded at the apex (this conical process is pointed in the males of the other three species) and, especially, the dorsal surface of first ventrite of <i>P. chloe</i> <b>sp. n.</b> is raised in the middle from the base up to about 2/3 of its length, while it is occupied almost for the entire length of the ventrite by a median longitudinal oval-shaped depression in the males of the other three species. The female <i>P. chloe</i> <b>sp. n.</b> is easily distinguished because its last abdominal tergite bears a long and stout median spine prolonged backwards (Figs 1A, 2D), while in the <i>P. aspromontanus</i> female the last abdominal tergite ends in a pointed tip (Fig. 2C) and the posterior margin of the last abdominal tergite of <i>P. neapolitanus</i> is rounded (Fig. 2A). The female of <i>P. lucanicus</i> is still unknown.</p> <p> <i>P. calabrus</i> (Reitter, 1910) is also present in Calabria, this species is easily distinguished from <i>P. chloe</i> <b>sp. n.</b> by the tegument of the head and the pronotum smooth and shiny, the features of the aedeagus (cfr. Fig. 1B and Figs 10-11 in Sabella 1992), the metaventrite of the male that is raised in the middle in a pointed conical process (rounded at the apex in <i>P. chloe</i> <b>sp. n.</b>), the dorsal surface of the first ventrite of male that is traversed almost for its entire length by a median longitudinal oval-shaped depression (raised in the middle from the base up to about 2/3 of the ventrite length in <i>P. chloe</i> <b>sp. n.</b>). The last tergite of the female of <i>P. calabrus</i> is triangular (bearing a long and stout median spine in <i>P. chloe</i> <b>sp. n.</b>) (cfr. Figs 2B and 2D).</p>Published as part of <i>Sabella, Giorgio, Viglianisi, Fabio Massimo & Bekchiev, Rostislav, 2019, A new species of Pselaphogenius Reitter, 1910 of the fiorii species group from southern Italy (Coleoptera, Staphylinidae, Pselaphinae), pp. 387-394 in Zootaxa 4585 (2)</i> on pages 388-392, DOI: 10.11646/zootaxa.4585.2.12, <a href="http://zenodo.org/record/2637282">http://zenodo.org/record/2637282</a>

St. Pk., VI- 25-1995, Godwin, Marqua, & Wolfe, UV (TAMU, 1 M). Description. BODY: Length 1.72 –2.00 mm; orange-brown to brown; setae on head and pronotum short, curved and suberect, over rest of body longer and decumbent. Head: surface smooth, shining, punctures indistinct. Antennomeres III-VI longer than wide, VII as long as wide, VIII slightly transverse, IX as long as wide, X slightly longer than wide, VIII about two-thirds width of IX (Fig. 31 D). Setose are of median vertexal fovea slightly smaller than those of lateral foveae. Pronotum: surface smooth, shining, punctures indistinct. Setose area of median antebasal fovea varying from about same size to about two-thirds size of lateral antebasal foveae. Elytra: with faint microreticulation, punctures indistinct, discal stria extending to about four-fifths of elytral length. Abdomen: disc smooth, shining, punctures indistinct; basal striae of tergite 1 about one-fourth paratergite length, slightly divergent, separated at base by one-half tergite width; setose brush between bases of striae short. MALE: Antennae and trochanters not modified. Metaventrite with triangular setose patch arising between metacoxae present but not distinct. Tergite 1 with apex deflexed in middle third, appearing slightly emarginate at middle, setae along apex longest in areas of deflexed area and obscuring it (Figs 31 A–B), in lateral view tergite 1 only slightly protruding above base of tergite 2; tergite 2 with slightly arcuate transverse carina at base below apex of tergite 1, area anterior to carina impressed, disc at middle posterior to carina with two shallow longitudinal impressions that diverge slightly toward apex, impressions vary from distinctly bifoveate to obscure (Figs 31 A–C); in lateral view tergite 1 with disc convex, 2 flat, 1–4 close to confluently curved. Abdominal ventrites broadly rounded. Metatibiae thin, narrow at base, gradually widened to near apex, mesal margin of apical fifth with brush present (Fig. 31 E). Aedeagus 0.42 mm long; with dorsal plate abruptly narrowed in apical half to form elongate thin finger-like lobe; parameres with distinct preapical constriction, with three thickened setae on lateral margin at anterior angle of constriction, flattened hyaline seta near mesal margin, thickened to middle and aciculate to apex; internal sac with two large curved spines (Fig. 31 F). FEMALE: Lacking modifications of the abdominal tergites, otherwise similar to the male, including presence of the metasternal patch of setae. Collecting data. The one series was collected by sweeping at night along a river; individuals were taken due to their attraction to ultraviolet light, and one was found in an area of gypsum flats. Specimens were taken from April to August. Distribution (Fig. 43 A). Collected in the shortgrass prairie area of the southern portion of the plains states from Kansas to west Texas. Comments. This species is distinct in the form of male tergites 1 and 2. Tergite 1 has the apical margin slightly deflexed at the middle, and tergite 2 has a quadrate impression of varying distinctness, defined laterally by the two shallow longitudinal impressions. The two lateral impressions in the broader impression of the basal portion of male tergite 2, plus its distribution in the high plains near the Rocky Mountains leads to the ready recognition of this species. Closest is B. chisos, which has a semicircular basal area of tergite 2 roughened and indistinct flattened/ modified, but this area reaches only to the midpoint of the disc and the discal impressions of B. kiowa are suggested but are much shorter. Etymology. The name is based on the name of one of the native American groups that lived in the area that this species occurs.Published as part of Chandler, Donald S., Sabella, Giorgio & Bückle, Christoph, 2015, A revision of the Nearctic species of Brachygluta Thomson, 1859 (Coleoptera: Staphylinidae: Pselaphinae), pp. 1-91 in Zootaxa 3928 (1) on pages 71-73, DOI: 10.11646/zootaxa.3928.1.1, http://zenodo.org/record/28805

Spectral-domain OCT evaluation of Nd:YAG laser treatment for Valsalva retinopathy
No full textPurpose: To describe the spectral-domain optical coherence tomography (SD-OCT) findings in a patient with a premacular hemorrhage due to Valsalva retinopathy treated with Nd:YAG laser. Methods: Serial SD-OCT examinations were performed before and after Nd:YAG laser treatment to identify the cleavage plane of blood accumulation, as well as the exact location of the areas targeted by the laser spots and the different involvement of the affected retinal layers. Results: The SD-OCT scan above the level of settled blood showed that the cleavage plane was located under the internal limiting membrane (ILM). A raster box of 48 horizontal scans centered on the treatment area identified the two spots of ILM targeted by laser. The hyporeflective perforations appeared along an ILM still detached from the underlying retinal layers. Two months after treatment, the blood was completely reabsorbed. The ILM appeared reattached in the previously detached area. Only a mild thickening of the ILM remained visible at the laser-treated spots. Conclusions: SD-OCT evaluation of Nd:YAG laser treatment for Valsalva retinopathy confirmed the cleavage plane of the premacular hemorrhage. In addition, it revealed the exact location of the ILM disruptions caused by the laser spots, and the safety of the procedure, with no involvement of the underlying retinal layer

Elytra wider (0.51 mm) than long (0. 40 mm) and longer than pronotum, and gradually widen from the base to the apex. Two basal foveae; sutural stria reaching apical part of elytra with three very small adjacent foveae; discal stria reaching about two thirds of elytral length. Humeri not distinctly protruding followed by a weak lateral depression. Hind wings absent. Abdomen distinctly longer than both pronotum and elytra together, the first three visible tergites having the same length. Posterior margin of 2 nd ventrite slightly raised in the middle; posterior margin of 3 rd ventrite strongly raised and forming an open cup-shaped structure in the middle (Fig. 1); the central part of the 4 th ventrite depressed having the middle part of posterior margin raised as a form of lamina at 90° in such a way that it fits into the cupshaped structure just described and apically slightly curved posteriorly (Fig. 2). Legs with protibia widest in the middle (Fig. 9) with mesal margin sinuate in distal half, apically having a short rounded process; mesotibiae slightly enlarged in the apical third with a similar terminal process as in the protibiae. Aedeagus (Fig. 7) length 0.33 mm, with well-developed slender parameres widest in the middle, left paramere with two apical setae and right paramere with one; two additional medial setae are also present towards the centre of each paramere.

Body (Fig. 5) length 1.80 mm entirely light reddish with yellow palpi and legs. Pubescence and tegument as in male. Head as in male, wider (0.31 mm) than long (0.21 mm). Eyes well developed and protruding with 25–27 facets. Antennae similar to those of male. Pronotum similar to that of male, also for the foveae system on dorsal surface, wider (0.36 mm) than long (0.31 mm). Elytra wider (0.44 mm) than long (0.33 mm), similar to those of male, only less distinctly enlarged from base to apex. Abdomen as in male in dorsal view, and with unmodified abdominal ventrites. Legs unmodified. Telisternite as in figure 11. Comparative notes. Faronus rica sp. nov. belongs to the F. hispanus species group (Sabella 1993) characterized by males having secondary sexual characters on abdominal ventrites, aedeagus with sinuate parameres, well sclerotized median part bearing multiple small spiniform processes apically. The group currently accommodates F. hispanus Saulcy, 1870, known from Portugal (Algarve), Spain (Catalonia, Valencia, Andalusia) and northern Algeria; F. insularis Sainte-Claire Deville, 1908, endemic to Sardinia and circum-sardinian islands and southern Corsica; F. siculus Fiori, 1913, endemic to Sicily, F. insignis Besuchet, 1958, known from the Balearic Islands (Majorca and Minorca), and F. rica sp. nov. endemic to Malta. Faronus rica sp. nov. is closely related to F. siculus with which many morphological characters are shared. It differs from this species on the basis of the following features: (i) protibia of male widest in the middle with mesal margin sinuate in distal half (cfr. Figs. 9, 10); (ii) left side of median part of aedeagus pointed apically (cfr. Figs. 7, 8); and (iii) the highly modified 3 rd and 4 th ventrites having a strongly raised open cup-shaped structure in the middle (on 3 rd ventrite) and a 90° raised lamina (on 4 th ventrite) which fits into the cup-shaped structure and apically curved posteriorly (cfr. Figs.1-4). Females of both species are impossible to discriminate on the basis of morphological features. Some morphological differences in the apical region of the telisternite were found and these are illustrated in figures 11 and 12. Ecological notes. The two specimens of Faronus rica sp. nov. were collected in November by sifting leaf litter under Ceratonia siliqua, in a valley system at 50 m of altitude, along with numerous specimens of Tychus opuntiae (Schmidt-Goebel, 1836). Wied Babu (Fig. 6) is a fine example of a river valley and creek. The area is rich in endemic species such as the National Plant for Malta (Cheirolophus crassifolius) for which Wied Babu is the type locality. Etymology. This species is dedicated to Yves and Patricia Rica, a French family residing in Malta who are always very helpful and contribute financially for entomological research work carried out by the corresponding author in Malta. They offered free accommodation to many delegates present at the 4 th International Congress of Biodiversity held in Malta (13-16 th November 2017) and thereafter, this provided the right opportunity for the present authors to do intensive field work and to discover the new species which we gladly and proudly dedicate to them.Published as part of Kurbatov, Sergey A., Mifsud, David & Sabella, Giorgio, 2019, A new species of Faronus Aubé, 1844, endemic to Malta (Coleoptera, Staphylinidae, Pselaphinae), pp. 417-422 in Zootaxa 4571 (3) on pages 418-420, DOI: 10.11646/zootaxa.4571.3.9, http://zenodo.org/record/261280
Mitochondrial genome of Sabella spallanzanii (Gmelin, 1791) (Sabellida: Sabellidae)
No full textWe report the mitochondrial genome of Sabella spallanzanii, an invasive Mediterranean sabellid introduced to Australia and New Zealand. The mitogenome is 15,581 bp long and consists of 38 genes, including 13 protein coding genes, two rRNA genes, and 23 tRNA genes. It shows deviations from the putative annelid ground pattern, such as gene order re-arrangements and regions encoding on the negative strand. It is, however, very different from the mitogenome of the closely related serpulid, Spirobranchus giganteus. Phylogenetic analyses of the mitochondrial genes support a sister relationship of Sabella spallanzanii and Spirobranchus giganteus.</p
