Tennantite-(In), Cu-6(Cu5In)As4S13, was approved as a new mineral species from the Pefka epithermal ore deposit, Alexandroupolis, Evros, Western Thrace, Greece. It was identified as anhedral grains, up to 0.1 mm in size, intimately associated with roquesite, galena and tennantite-(Fe) in quartz gangue. In reflected light, tennantite-(In) is isotropic, pale grey in colour. Reflectance values for the four COM wavelengths in air are [lambda (nm): R (%)]: 470: 31.2; 546: 30.7; 589: 30.5; 650: 28.8. Electron microprobe analysis gave (in wt.% - average of 7 spot analyses): Cu 43.83(95), Mn 0.22(8), Fe 0.65(46), Zn 0.57(12), Cd 0.16(5), Pb 0.26(2), As 14.38(3.00), In 5.05(59), Sb 7.74(3.08), Te 0.48(9), S 26.18(79), total 99.52(78). The empirical formula of the sample studied, recalculated on the basis of Sigma Me = 16 atoms per formula unit, is Cu10.82In0.69Fe0.18Zn0.14Mn0.06Cd0.02Pb0.02As3.01Sb1.00Te0.06S12.81. Tennantite-(In) is cubic, I$\bar 4$3m, with a = 10.285(2) & Aring;, V = 1088.1(6) & Aring;(3) and Z = 2. The five strongest reflection lines in the calculated powder X-ray diffraction pattern are [d in & Aring;, (I), hkl]: 2.969, (100), 222; 2.571, (20), 400; 1.878, (7), 521; 1.818, (42), 440; and 1.551, (21), 622. The crystal structure of tennantite-(In) has been refined by single-crystal X-ray diffraction data to a final R-1 = 0.0253 on the basis of 240 unique reflections with F-o > 4 sigma(F-o) and 23 refined parameters. Tennantite-(In) is isotypic with other members of the tetrahedrite group. Indium is hosted at the tetrahedrally coordinated M(1) site, in accord with the known preference of this element for tetrahedrally coordinated bonding environments.
A total of 147 localities in Slovenia and three sites in Croatia were surveyed for Psychodidae (Diptera) during fieldwork conducted between 1999 and 2001. In total, 93 species were recorded, of which 28 are reported for the first time in Slovenia, increasing the known Slovenian Psychodidae to 93 species, and three are newly documented for Croatia. Species richness per locality ranged from single-species occurrences to 12 species, reflecting the diversity of aquatic and riparian habitats. According to IUCN and national assessments, five species are Critically Endangered (CR), eight Endangered (EN), seven Vulnerable (VU), and 19 Near Threatened (NT) at the national level. Thus, 42% of recorded species face some level of conservation concern. These results significantly expand the knowledge of Central European psychodid fauna, highlight previously undocumented distribution data, and underscore the importance of protecting aquatic and riparian ecosystems for conservation of threatened species.
New data on the distribution of 40 species of Dytiscidae are provided. Most of these records are from the Balkan Peninsula (Bulgaria, Greece, Montenegro, North Macedonia and Romania), northern Africa (Algeria and Libya), the Caucasus Region (Armenia, Azerbaijan and the South European Territory of Russia), Central Asia (Kyrgyzstan, Tajikistan and Uzbekistan) and the Himalaya Region (Bhutan, northern India and Nepal). Two species, Hygrotus rufus (Clark, 1863) and Copelatus bacchusi Wewalka, 1981, known previously only from the Palearctic, are reported for the first time from the Oriental Region. Eight species are reported for the first time from Bhutan. Seven of these species, including three species new for the Palearctic Region, were provided by the insect dealer Jingke Li, but the provenance of the specimens is regarded as questionable. The necessity of publishing new records before accepting them for catalogues, e.g., the Catalogue of Palearctic Dytiscidae, is emphasised. Finally, previously published records of four incorrectly identified species/subspecies are corrected.
The Afrotropical species of Nothris are revised, and the genus is re-described, incorporating the Afrotropical species. A total of twelve species are recognized as valid, of which seven are described as new based on morphological and molecular evidences: N. mediofasciatasp. nov. (South Africa and Lesotho), N. tornilineatasp. nov. (South Africa), N. basipunctellasp. nov. (South Africa), N. nigrovenatasp. nov. (South Africa), N. lativalvasp. nov. (South Africa), N. nyangensissp. nov. (Zimbabwe and South Africa), N. nigrisparsussp. nov. (South Africa). Additionally, the following taxonomic changes are proposed: Ptychovalva trimaculata Janse, 1960 is combined as Nothristrimaculata (Janse, 1960) comb. nov., Gelechia anagramma Meyrick, 1921 as Nothris anagramma (Meyrick, 1921) comb. nov., and Gelechia leucodoxa Meyrick, 1920 as Schizovalva leucodoxa (Meyrick, 1920) comb. nov.Gelechia (Brachmia) trigella Zeller, 1852 is transferred from family Gelechiidae to Autostichidae (under subfamily Symmocinae) and provisionally classified as Symmoca trigella (Zeller, 1852) comb. nov. Finally, the taxonomic status of Nothris dissidens Meyrick, 1913 is discussed, and the lectotype is designated for Gelechia obruta Meyrick, 1921.
We report the first record of Hydroptila ivisa Malicky, 1972 in Slovakia. The faunistic survey of caddisflies was conducted on the eastern slopes of the Vel'k & aacute; Fatra Mountains in the village of Blatnica (Turiec River Basin, central Slovakia) in 2024. One male and two females of Hydroptila ivisa were attracted by UV light traps at the Blatnick & yacute; potok stream. In 2025, the presence of the species was confirmed at the same locality with the capture of two additional females. Furthermore, one male and one female were recorded upstream in the Gadersk & yacute; potok stream, the main tributary of the Blatnick & yacute; potok stream, located within the Vel'k & aacute; Fatra National Park. This is only the third known location of the species in the Carpathians; consistent with its already known habitat preferences, it was found in the rhithral. We also present a list of caddisfly species recorded during the survey, which expands the known species diversity of the region.
