description: In order to understand how the cool circumgalactic medium influences the evolution of galaxies, it is crucial to characterize its structure and dynamics, which can in turn reveal what are the origin and fate of this gas and what is its link to the central galaxy itself. In this talk, I will present recent results obtained from the combination of different modeling techniques and various types of tomographic data of the cool/cold circumgalactic and interstellar media of galaxies at low and high redshift. I will show how, combining models and data through Bayesian inference, we have been able to refine our picture of the cool material surrounding galaxies and to improve our understanding of the baryon cycle and its gas inflows and outflows.

description: Subfamily Peloropeodinae Robinson, 1970
The subfamily Peloropeodinae was erected by Robinson (1970) for a number of small-sized genera that mostly share a flattened posterior mesonotum, veins R 4+5 and M 1 parallel, and with anterior preapical setae present on femora II and III. However, the male postabdomen of the included genera show a wide range of morphological structure, suggesting the subfamily is not monophyletic, but a heterogeneous assemblage. Further, Lim et al. (2010) state that based on molecular data, the dolichopodid subfamily Peloropeodinae fails the test of monophyly. Nevertheless, it serves as a “holding taxon” for a number of disparate mostly small-sized dolichopodid genera. Grichanov & Negrobov (2018) placed the fossil genus Palaeomedeterus Meunier in the subfamily, where it remains until its taxonomic position can be clarified.

Trichocera (Saltrichocera) sardiniensis Petrašiūnas, 2009: 62.
Material examined. Morocco: Oued à 15 km de Fifi, 26. II.2012, 1 ♂; Affluent Oued Akrir, 23. XI.2012, 1 ♀, 2♂; Oued Amsemlil Site 2, 16. XII.2013, 1 ♂; Maison forestière, 06.II–17. III.2015, 1 ♂ (malaise trap).
Remarks. The specimens from Morocco (Fig. 3) do not differ from those of the terra typica in the details of male and female genitalia, tarsal claws in male, and the antennae with swollen first flagellomeres in the males and, to a greater extent, in the females.
This is only the second record of this newly described species, known till now only from Sardinia, where it also occurs in the mountains above 1000 m (compare Table 1). Petrašiūnas (2009) rightly noticed a great resemblance of this species to Trichocera (Saltrichocera) borealis Lackschewitz, 1931. The only differences are smaller tarsal claws in males of T. (S.) sardiniensis. This species also has longer antennae which may develop so in warmer climate (compare discussion in Krzemińska et al. 2009: 142–3). Undoubtedly both species are mutual closest relatives, although T. (S.) borealis is known from the northernmost regions of Europe Palearctic (ex. Dahl & Krzemińska 2008), while T. (S.) sardiniensis occurs in the southernmost region of the genus distribution. This wide geographical disjunction of both species suggests postglacial history of their speciation initiated by separation of populations in the glacial period, when fauna from northern Europe was pushed south to refugia in the Mediterranean area. Subsequent division of populations in isolated refugia, and various histories of their recolonization northwards resulted in allopatric speciation and distribution. Such patterns were discovered among various taxa of fauna and flora; for a synthetical review see Hewitt (1999).

Gujaratmyia

description: Genus Gujaratmyia Bickel gen. nov.
Etymology. Gujaratmyia is the combination of the name of Indian state of Gujarat where Cambay amber occurs and the suffix - myia, Greek for “fly”. The gender is feminine.
Type species. Gujaratmyia rotunda Bickel sp. nov.
Diagnosis. [This generic diagnosis is based on a single male specimen and emphasizes characters considered to be of generic importance.] Body length about 1.1 mm; head large with respect to size of thorax, and ovate, higher than wide; face as narrow band separating eyes; postpedicel rounded, subtriangular, arista dorsal; posterior mesonotum apparently flattened; femora II and III each with distinct anterior preapical seta near 4/5; TII with strong ad seta at 1/3; veins R 4+5 diverging from M 1 near base, and becoming slightly bowed and subparallel with M 1 beyond level of dm-m crossvein; R 4+5 joins costa at 7/8, M 1 joins margin slightly behind wing apex; hypopygium forming ovoid cap over apex of abdomen, and with short distal appendages.
Remarks. Gujaratmyia is a monotypic genus, and the species G. rotunda has the posterior mesonotum apparently flattened, the dorsal postcranium is strongly concave, femora II and III have anterior preapical setae, and the slightly divergent veins R 4+5 and M 1, all characters reminiscent of the subfamily Enliniinae, discussed above.

The Circumgalactic Dictionary: A Simulation-based Guide for Interpreting CGM Observations
Creators: name: Anderson, Annelia
Publisher: name: Zenodo
Year: 2025
Subjects: models & simulations

description: Transverse absorption-line spectroscopy has proven to be a vital tool for observing the circumgalactic medium (CGM), but interpretation is complicated by ambiguity in identifying where absorbing gas is located along the sightline, and by the limited number of sightlines available per galaxy. Hydrodynamic simulations have also contributed significantly to our understanding of the CGM, mostly through comparison with observations. In this talk, I discuss an alternative approach - using simulations to interpret observations. Under development, the Circumgalactic Dictionary will be a guide for observers which predicts previously unattainable CGM gas properties given an input spectrum, including temperature, density, metallicity, 3d position and velocity, and information about the gas's history. The method consists of creating synthetic quasar absorption-line spectra using the IllustrisTNG simulations, deriving observables using a custom-built Voigt profile fitting pipeline, identifying gas along the simulated sightlines that contributed to absorption, and using them to train a Neural Network to map from observables to properties of the simulated CGM absorbing gas. Once completed and publicly released, the Circumgalactic Dictionary will predict probability density functions of physical properties, kinematics, and histories of clouds of absorbing gas, as well as the number of distinct clouds that caused absorption to distinguish between multiphase and multiple cloud scenarios. Built around the framework of Cosmic Origins Spectrograph UV observations, the Circumgalactic Dictionary will provide new insights to existing and future observations.

Traulia ferruginata Brunner von Wattenwyl, 1898: 249 (holotype – male: ‘ Celebes septentrionalis’; in Natural History Museum, Vienna); Kirby, 1910: 475; Bolívar, 1917: 627; Willemse, 1921: 28; Willemse, 1931: 264, figs. 111, 112; Willemse, 1935: 141.
Celebesia ferruginata: Ramme, 1941: 201, Pl. 12, fig. 6a; Willemse, 1957: 418; Monk & Butlin, 1990: 33; Otte, 1995: 290.
Measurements. Male: body 18–21; pronotum 5; tegmen 15; hind femur 12–12.5 mm.
Distribution. Indonesia: north part of Sulawesi (Tolitoli) (Willemse, 1957).
Notes. Brunner von Wattenwyl (1898) described Traulia ferruginata on the base of one male from the north part of Sulawesi (without definite locality) and one female from Borneo (Kina Balu). This female is not conspecific with male and probably belongs to Traulia bimaculata Willemse, 1932; therefore the female of Celebesia ferruginata is unknown until now (Willemse, 1957).

description: The present research investigated actual and perceived physical appearance attitudes within a romantic relationship. Past research has suggested that people are often inaccurate in perceiving the opposite sex's physical appearance ideals for one' own sex. Ninety-three heterosexual couples completed anonymous questionnaires measuring appearance satisfaction, perceived partner attitudes and effects, relationship satisfaction and sexual satisfaction. Evaluative ratings of appearance were taken from three perspectives — Self, Perceived Partner, and Actual Partner. For both sexes, all three perspectives were significantly different from one another. Regarding the accuracy of perceived partner attitudes about one's appearance, men and women were only modestly accurate and usually underestimated the degree to which their partner's approved of their looks. Women's perceived partner ratings were significantly higher than men'. When actual partner ratings were reviewed, this was in fact the case. For women, relationship and sexual satisfaction were best predicted by how favorably they rated their partner's appearance. Men's relationship satisfaction was associated with how favorably they assumed their partners rated them and how favorably they (men) rated their partner's appearance. Men's sexual satisfaction was predicted by how favorably they thought their partner evaluated them. Also, the Physical Appearance in Intimate Relationships Scale was further validated using couples. Finally, no ethnic differences in body image and appearance evaluations were found. Future research and limitations of the study were also discussed.

description: The diffuse Circumgalactic Medium (CGM) can be observed in absorption using gravitational arcs as background sources. In this talk, I will show the very first VLT/MUSE observations of a galactic-scale arc (Einstein radius ~ 3'') that probes the cool CGM (T ~ 10^4 K) of a lensing early-type galaxy (log M_h ~ 13) residing in a galaxy group at z = 1. This setup enables spatial mapping of Mg II ??2796, 2803 equivalent widths and kinematics at impact parameters of ~ 30 kpc measured at 10 spatially independent positions. Along with semi-analytical models, I will show how these tomographic data can put constraints on the possible origin and fate of the enriched gas around this early-type galaxy.

description: Spodocybe rugosiceps Z.M. He & Zhu. L. Yang, Mycokeys 79: 139, 2021 (Figs. 2h, 3e)
Chinese name: 皱ȅ灰ȅ杯伞
The detailed description refers to He & Yang (2021).
Habit and habitat:—Usually scattered to gregarious or caespitose, on the soil of coniferous forests dominated by P. yunnensis, known from the subtropical zone of Yunnan, China; July to September.
Distribution:— CHINA: Yunnan province (Kunming city, Yulong and Yunlong prefecture) at elevations ranging from 1900−2600 m.
Material examined:— CHINA. Yunnan province: Kunming City (AEDZ市), Fangwang Tree Farm (Ẁffi林场), 25°38.24'N, 102°52.24'E, elev. 2262 m, 22 September 2011, Zhu-Liang Yang 5586 (KUN-HKAS 71071, GenBank Acc. No.: nrLSU = MW763011, ITS = MW762886).
Comments:—According to the previous description (He & Yang 2021), S. rugosiceps is the type species of the genus Spodocybe which is distinctive by its small basidiomata (pileus 0.5−2 cm diam.), grey-brown to grey-black finely tomentose pileus, elongate basidiospores (5–6 × 3–3.5 μm, Q = 1.55–1.95, Q m = 1.73 ± 0.14), 4-spored basidia, and growing in coniferous forests. The epithet “rugosiceps ” refers to its rugose pileus. Based on our field observation, the rugose pileus might be a valid character at only young period, however, this character is insignificant when mature. This species is known to occur in southwest China.

Ischnogaster eximius Bingham, 1890: 244.
This species is similar to E. latebricola Saito, sp. nov., but can be distinguished from the latter by the combination of the following characters: clypeus and supraclypeal area less convex; mesoscutum with fine, shallow punctures; scutellum less convex (Fig. 49); terminal three antennal flagellomeres orange; metasoma brown, but second to fourth terga posteriorly black; second sternum entirely black; wings semi-hyaline, brown, darker than in E. latebricola; legs brown, fore femur and tibia yellow beneath.
Material examined. Sri Lanka: 1Ψ (RMNH), Kanneliya Jungle, Gal[le] Dist., 13–16.viii.1972, K.V. Krombein & P.B. Karunaratne; 1Ψ (RMNH), Induruwa (Jungle), Gilimale, Rat[napura] Dist., 13–15.iii.1979, K.V. Krombein et al ..
Distribution: India; Sri Lanka; China: Yunnan (recorded by Dong & Otsuka 1997, but needs confirmation); Thailand; Malaysia: Peninsular Malaysia.
Note: Dover and Rao (1922) described Stenogaster eximioides from “Nadgani, Nilgiri Hills” (Tamli Nadu Province, India) and Dover (1925) synonymized it with Stenogaster eximia. Bell (1936) described Paravespa eva from Bombay (= Mumbai, N. Kanara District, India). Das and Gupta (1984) reinstated eximioides as a subspecies of E. eximia and treated Paravespa eva as a junior synonym of E. eximia eximioides. As no specimens from India that match the color pattern of eximioides are available for the present study, the taxonomic status of both Stenogaster eximioides Dover and Rao, 1922 and Paravespa eva Bell, 1936 deserves future study.

Unveiling the cool CGM around quiescent galaxies with galaxy-galaxy lensing

description: The processes that cause some galaxies to stop forming stars and how such galaxies stay quiescent remain open questions. While quiescent galaxies have comparable amounts of cool gas in their outer circumgalactic medium (CGM) compared to their star-forming counterparts (e.g. Chen+ 2018), they have significantly less interstellar gas (Magdis +2021). Theories point to dynamical interactions with the hot corona as the primary process preventing cool gas from reaching the galaxy (Afruni+2019). However, there is a lack of understanding of the inner regions of the CGM of quiescent galaxies that is due to limitations in standard quasar-sightline methods, which lack spatial information in the needle-like beam. I will present work using galaxy-galaxy scale strong lenses which probe the inner 10--20 kpc of massive quiescent galaxies. We use Keck/KCWI IFU spectroscopy to spatially resolve MgII absorption around the quiescent galaxies tracing large amounts of cool (10^4K) atomic gas. Even at these close impact parameters, we find a comparable amount of cool gas compared to star-forming galaxies. Additionally, we show through detailed lens modelling of high resolution Hubble imaging that the lens model of one system reveals a diffuse component of significant mass consistent with the spatial extent of the MgII absorption. Our work shows the power of galaxy-scale gravitational lenses to not only probe the gas in the inner regions of the CGM, but to also independently probe the mass of the CGM due to its gravitational effect.
