Abstract
In this paper, the plant lists of the genus Iris (Iridaceae family) grown in Zagreb Botanical Garden of the Faculty of Science since 1895 are studied. Synonymy, nomenclature and origin of plant material were sorted. Lists of species grown in the last 124 years have been constructed to show that during that period at least 273 taxa of wild and cultivated irises inhabited the Garden’s collections. Today we have 168 species, cultivars and hybrids.

Abstract
In the present paper we report first observations of the invasive sycamore seed bug, Belonochilus numenius (Say, 1832) in Croatia. So far, we recorded the species in five localities in Croatia, one in Zagreb, two in Split and two in and around Dubrovnik. All the records originate from the urban areas with Plane trees on which the species feeds.

Abstract
This species was deliberately introduced from Canada to Russia in 1969 in order to control the spread of the invasive plant Ambrosia artemisiifolia L., and has so far spread across eastern and parts of central Europe, including Serbia and Hungary. With this survey A. candefacta has for the first time been recorded in Croatia, which confirmed the further spread of this species toward western Europe.

Abstract
In this study we present: two species of caddisflies new for Croatian fauna from the family Hydroptilidae (Hydroptila simulans Mosley, Orthotrichia costalis Curtis), first DNA barcoding of caddisfly species in the Krka National Park and a discussion about recorded caddisfly fauna in the Krka NP from this study. From a faunistic point of view several species are interesting: Hydropsysche mostarensis Klapálek, Hydroptila simulans Mosely, Hydroptila forfcipata Eaton, Orthotrichia costalis Curtis and Tinodes pallidulus McLachlan. For the species Oecetis notata Rambur we have recorded interesting taxonomical remarks. Furthermore, within this study we used DNA barcoding which showed to be a very good and useful method for identification of very small and morphologically similar species from the family Hydroptilidae, or females from the family Psychomyiidae.

Abstract
This paper presents the results of a detailed floristic study conducted during three consecutive years (2015-2017) in the central part of Kosovo, in the mountain of Golesh. The studied mountainous area is unique by reason of its ecosystems and has a high degree of diversity of regional flora. Because of its specific harsh environment the area as a whole contains a considerable amount of endemic and rare plant taxa. Therefore, the flora of different habitats of the area has been properly investigated and must be adequately protected. All recorded taxa in this study correspond to the collected voucher specimens. Conservation statuses for endangered taxa were also proposed based on the relevant literature data. As a result of the research, 62 families, 199 genera, and 295 taxa (species and infraspecific taxa) of vascular plants were recorded, including eight endemic plant taxa and, in total, twelve endangered plant taxa. Growing on Mt Golesh are one critically endangered (Klasea radiata), three endangered (Narcissus poeticus subsp. radiiflorus, Haplophyllum boisserianum and Daphne cneorum), two vulnerable (Centaurea albertii and Galatella albanica), two near threatened (Paramoltkia doerfleri and Potentilla visianii) and four least concern plant taxa (Halacsya sendtneri, Linum flavum, Forsythia europaea and Polygala doerfleri), indicating that this area has a high conservation value and the necessity for research.

Abstract
One fifth of all described water mite species show clear preferences to spring ecosystems. The main goal of this research was to contribute to the knowledge of water mite assemblages, species richness and abundance in karst springs, with a special emphasis on comparing rheocrene and limnocrene spring ecosystems. The limnocrene spring Modro Oko in the Southern Dalmatia had only one water mite species recorded in the studied period, showing very low abundances, whereas the rheocrene spring of Jadro River in the Central Dalmatia showed both higher species richness (ten taxa recorded) and abundance. First records of two water mite species of the family Hygrobatidae from karst springs situated in the coastline area of Croatia are provided and discussed: Hygrobates setosus Besseling, 1942 and Atractides distans (K. Viets, 1914). Including these two additional records, a total number of 88 water mite species are recorded from Croatia so far.

Abstract
The genus Bathyscidius is, according to the body size, one of the smallest leptodirines. Six species, one of them including two subspecies, have been described to date. This study has undertaken a taxonomical revision of the genus Bathyscidius s. str. Existing species are re-described, supported with detailed morphometry and, for the first time, with the description of male and female internal morphological characters. Three newly discovered species B. mljetensis, B. komajiensis and B. orjensis are described; one subspecies B. t. fallaciosus is elevated to species rank and one of the existing species B. remyi is synonymized. For the two geographically isolated species, B. rambouseki and B. tomoricensis, a new subgenus, Ionobathyscidius, is established.

Abstract
The collection of orchids within Herbarium Croaticum sensu stricto keeps as many as 1373 herbarium sheets, belonging to 91 taxa (25 genera, 76 species, 11 subspecies and four hybrids). The majority of the collection originates from Croatia while the rest are from neighbouring countries (Slovenia, Serbia, Bosnia & Herzegovina, Italy, North Macedonia and Montenegro). The most numerous genera are Orchis, Ophrys and Anacamptis, while the most numerous taxa are Gymnadenia conopsea, Platanthera bifolia, Anacamptis morio, Neotinea tridentata, Cephalanthera longifolia and Dactylorhiza maculata. The oldest herbarium sheets date back to 1883 and the average age of the collection is 113 years. The main collectors are Ljudevit Rossi, Dragutin Hirc and Ambroz Haračić. The collection keeps holotypes and isotypes of Epipactis rivularis and Ophrys dinarica, while exsiccates of Malaxis monophyllos, Herminium monorchis and Ophrys × muellneri are the only evidence of their existence in Croatia. All sheets were digitized and are publically available via virtual herbarium.

Abstract
In Europe the Phryganeidae family comprises 7 genera and 20 species. In Croatia, 6 species have been recorded from this family, and four of them recorded and collected in the last five years have been DNA barcoded. In terms of faunistic research, most interesting is the record of Trichostegia minor Curtis, 1834 from the region of the Gacka River in Lika, in upland Croatia. Up to now four species have been included in the BOLD system with 6 DNA-barcoded specimens. From the Gacka River area, 11 specimens of 8 species, including T. minor, have been barcoded and included into the BOLD system. Phylogenetic research based on DNA barcode data has shown some interesting results. Specimen of T. minor collected in the area of the Gacka River is clustered with a specimen of this species from Austria into a separate subgroup, which shows minor molecular specifics. Phylogenetic analysis has confirmed the justification of the status of a subspecies from Mongolia, Phryganea grandis rotundata Ulmer, 1905. Future Trichoptera fauna research in Croatia will continue investigations of the family Phryganeidae in various parts of the country for the purpose of ascertaining the detailed distribution of all the species recorded, to enable finding some other previously missing species, as well as collecting and DNA barcoding of Hagenella clathrata (Kolenati, 1848) and Oligostomis reticulata (Linnaeus, 1761). With respect to these species, the data will also be useful for the area of conservation biology, necessary for their protection and for the protection of the sites in which they occur, for it is clear that these are very rare species in Croatia, T. minor also belonging to this group: 50% of the species from this family recorded in Croatia are rare and very rare species.

Abstract
In this pilot-study, we investigated the short-term effects of natural stream discharge on the stream water quality at six sites located along the two urban streams - Bliznec (B) and Veliki potok (VP) - flowing through Zagreb, capital of Croatia. The streams source within the Medvednica Nature Park (upper stream reaches) and flow along an increasing urban gradient in central Zagreb region (middle and lower stream reaches). The following physico-chemical parameters were measured every other day over the two-week period in October 2017: stream discharge, water temperature and oxygen concentration, conductivity, pH, chemical oxygen demand (CODKMnO4), and in-stream concentrations of nutrients (nitrites, nitrates, orthophosphates). Nutrients were the most variable parameters during the two-week period. Bliznec generally showed significantly higher discharge and oxygen levels compared to Veliki potok, which had significantly higher CODKMnO4 and nitrite concentrations. Middle and lower stream reaches had significantly higher temperature, nitrite and nitrate concentrations in comparison to the upper reaches. Several physico-chemical parameters (discharge, nitrites, nitrates, orthophosphates, conductivity and CODKMnO44) evidenced to be highly synchronized between the two streams, among the three stream reaches and among the six sites over time, which was corroborated by relatively high proxy for temporal concordance (τ > 0.60) of these parameters. This indicated that environmental conditions (stream water quality) synchronously vary across space and over time along our study streams. The data also revealed significant between-site and temporal changes of the physico-chemical parameters after a major storm event. Moreover, conductivity was found to correlate with discharge. Findings of the present pilot study indicate that urban streams are very dynamic ecosystems showing an increased sensitivity to environmental changes, such as anthropogenic influences and local weather conditions. We suggest that the extensive environmental variability of urban streams should be considered in the scope of ecological studies and environmental management approaches within urban zones.

Abstract
The first checklist of pyraloid moth species in Croatia, published in 2019, includes 362 species. A provisional checklist and bibliography of the Pyraloidea of the Balkan Peninsula was published in 2018, but because of unfortunate overlaps in timing, that work was not considered in the later publication. This present article provides new data on 16 additional species included in the earlier work. Taking these into account the number of Pyraloidea species occurring in Croatia raises to 377 and includes 207 Crambidae species plus 170 Pyralidae taxa. This represents about 45% of the European pyraloid moth fauna. A revised checklist is presented now. Another 31 species, not included in the 2018 provisional checklist for the Balkan Peninsula, but which are listed in the 2019 Croatian checklist of Pyraloidea are also discussed. This is followed by a comparison with the pyraloid fauna of other countries from the region.
