Remarks Under the name Nemastoma (Lugubrostoma) triste pluridentatum, Hadži (1973a) described four taxa: a) N. pluridentatum (Hadži, 1973) stat. nov. (Hadži 1973a: fig. 33a) from Mt. Paljenik (1943 m a.s.l.) in the Vlašić Mts, Bosnia, b) a hybrid N. b. gruberi ssp. nov. × N. b. schmidti ssp. nov. (Hadži 1973a: fig. 33b, č) from the surroundings of Novo mesto, Slovenia, c) a hybrid N. b. martensi ssp. nov. × N. b. schmidti ssp. nov. (Hadži 1973a: fig. 33c) from the surroundings of Novo mesto, which Hadži (ibid.) erroneously cited for Mt. Vlašić, and d) Nemastoma b. schmidti ssp. nov. from Mt. Šmarna gora, Slovenia (Hadži 1973a: fig. 34a), from the surroundings of Ljubljana (Hadži 1973a: fig. 34b), and from the cave Jama Sv. Janeza pri Prestranku near Postojna, Slovenia (Hadži 1973a: fig. 34c). Figs 33 and 34 were drawn freehand; consequently, shapes and dimensions only partly correspond to the real measurements. Hadži’s original microscopic preparation labeled “ Nemastoma bidentatum Roewer pulli, A-1065 (Novo Mesto), legit Karaman” includes two males and a female, but no juveniles. Hadži (ibid.) drew some details of the males, including damaged legs; see remarks on Nemastoma (Stridulostoma) seliskari Hadži, 1973 under N. b. martensi ssp. nov. × N. b. schmidti ssp. nov. Given that some important parts, e.g., Pa of one male, are missing, Hadži probably made this incomplete preparation after observation of the specimens under a microscope. In his original paper (Hadži 1973a), the type specimen and the type locality of N. pluridentatum stat. nov. were not designated, but he did that in the catalogue (Hadži 1973b: 13) under a mistyped name: “ N. (L.) triste pleuridentatum Hadži, 1973 ”. There he wrote: “Loc. typ.: Novo mesto ”. Since the specimens from this locality belong to the above-mentioned hybrids, Novo mesto cannot be the type locality of N. pluridentatum stat. nov.; that is the first-mentioned location in Bosnia, as fig. 33a (Hadži 1973a) is the only drawing that refers to this taxon. Unfortunately, only the preparation of one Ch, one Pa and four legs of the male holotype are preserved, while the body, as well as a further male and female mentioned by Hadži (1973a: 44) are missing. Because of the lack of any information on the Pe, the saw on Fe IV in preserved legs is the only available character allowing us to place this taxon into the N. b. complex, interpreted as N. ? bidentatum pluridentatum (Novak 2005a: fig. 34) or N. b. pluridentatum (Schönhofer 2013). In 2019, we visited the type locality Mt. Paljenik, but we did not find further specimens of N. pluridentatum. Instead we found a new, much different N. kozari sp. nov. there, which unlikely hybridize with N. pluridentatum stat. nov. Consequently, we ascribed the species status to N. pluridentatum. See remarks under N. relictum stat. nov., N. kozari sp. nov. and hybrids N. b. gruberi ssp. nov. × N. b. schmidti ssp. nov. and N. b. martensi ssp. nov. × N. b. schmidti ssp. nov. Distribution Bosnia and Herzegovina, endemic to central Bosnia, probably endemic to the Vlašić Mts. Type locality: Mt. Paljenik in the Vlašić planina Mts, Bosnia, (44.29° N, 17.64° E, 1933 m a.s.l.), Bosnia and Herzegovina. Ecology Nemastoma pluridentatum stat. nov. inhabit the highest peak areas with the Mastgrass Gentianello crispatae-Nardetum strictae Redžić 1990 communities. Phenology: adults probably eurychronous.

Remarks In Hadži’s original preparation, labelled “ Nemastoma bidentatum Roewer pulli”, with two cover glasses on the same microscope slide, there are two males and a female. One male corresponds to the type specimen of Nemastoma (Stridulostoma) seliskari Hadži, 1973 (Hadži 1973a). For this species, Hadži (ibid.) founded a new subgenus Stridulostoma based on the existence of an alleged “stridulatory organ” on the Fe III (Hadži 1973a: figs 37č–d). Gruber (1976: 797) explained that the stridulatory organ alone does not justify establishing of a new subgenus, especially because this new species differs from N. (Lugubrostoma) triste pluridentatum Hadži, 1973 exclusively by possession of this organ, and accordingly, synonymized Stridulostoma with Nemastoma. Following these remarks, Schönhofer (2013: 36) synonymized N. seliskari with N. b. pluridentatum. We found that the portion of the Fe III, identified by Hadži (1973a) as a stridulatory organ in the type specimen, is in fact a depression-damage, caused by desiccation. Moreover, such damage is present in nearly all (sic!) the other femora of this freshly moulted specimen, but nothing resembles the fine lamellated structure shown in Hadži’s drawing (1973a: figs 37č–d). No similar structure was found in the specimens of Nemastoma collected later on Mt. Mirna gora. One might imagine that a careless inspection under a microscope at low magnification could result in the illusion of a ʻstridulatory organʼ. However, the drawing of its lamellae cannot be considered anything but a pure fabrication. Moreover, Pa-Fe in Hadži (1973a: fig. 33c), being under the same cover glass in the preparation, belongs to the same specimen, although Hadži (ibid.) ascribed it to N. (Lugubrostoma) triste pluridentatum. See remark under N. pluridentatum stat. nov.

Remarks In Slovenia, N. b. sparsum lives in the northeast, at the margins of the Pannonian basin (Martens & Gruber 1968; Martens 1978; Kovač 1997). The type series deposited in Naturhistorisches Museum Wien (Gruber & Martens 1968) also includes N. b. gruberi ssp. nov. distributed south of the Sava River in Slovenia and Croatia. All prior identifications of N. b. sparsum south of the Sava River (Novak et al. 1995, 2002; Novak 2005b) refer to N. b. gruberi ssp. nov. Martens (1978: 112) reported a sparsum -like population living in the mountain pine association (Hyperico grisebachii-Pinetum mugo Horvat 1938) on Mt. Veliki Snežnik (the peak at 1796 m) at least up to the altitude of 1650 m a.s.l. These individuals may refer to N. b. gruberi ssp. nov., N. b. martensi ssp. nov. or N. b. sneznikensis ssp. nov. Individuals from Bosnia and Herzegovina (Mt. Plasa, Jajce) and Dalmatia, Croatia (Split) (Gruber & Martens 1968) should be revised for identification. See remarks under N. b. gruberi ssp. nov. and N. b. gruberi ssp. nov. × N. b. schmidti ssp. nov., N. b. martensi ssp. nov. and N. b. sneznikensis ssp. nov. Distribution Central and eastern Europe: Austria, Bulgaria, Bosnia and Herzegovina, Czech Republic, Denmark, Hungary, Croatia, Montenegro, Romania, Russia, Slovakia, Slovenia, Serbia and Turkey (Gruber & Martens 1968; Staręga 1976; Martens 1978, 2006; Mučalica 1988; Klimeš 2000; Komposch 2002; Komposch & Gruber 2004; Schönhofer & Holle 2007). Vertical distribution: 120−1650 m a.s.l. (Komposch 1999; Komposch & Gruber 2004), in Slovenia 155–644 m a.s.l. Type locality: Sonnenberg (47.88° N, 16.31° E, 480 m a.s.l.), Leitha Mts, Burgenland, Austria. Ecology Nemastoma b. sparsum is a lowland and hilly land subspecies inhabiting various types of acidophilous and neutrophilous forests of Fagus sylvatica, Carpinus betulus L. and Quercus petraea (Matt.) Liebl., riverine forests, and thermophilous scrubs in north-eastern Slovenia, mostly on non-calcareous soils. Phenology: adults eurychronous.

Remarks Regarding external morphology, N. b. sneznikensis ssp. nov. is very similar to N. relictum, including the habitus, the similarly shaped Pa and relatively short legs. No individuals belonging to the subspecies were found in the last decade. See remarks on taxa of Nemastoma on Mt. Snežnik under N. b. gruberi ssp. nov. Distribution Despite over 30 collections, this taxon has been recorded only in a limited area on Mt. Snežnik. Endemic to Mt. Snežnik, southern Slovenia. Type locality: Mt. Snežnik (45.59�� N, 14.44�� E, 1553 m a.s.l.), Slovenia. Ecology Nemastoma b. sneznikensis ssp. nov. is a psychrophilous subspecies. To date it has been recorded only in a cold, well-drained, deep mull humus Dinaric Pinus mugo scrub in contact with the Dinaric Fagus sylvatica ��� Abies alba treeline on calcareous soils. Likely, it inhabits other cold habitats, like scree and stone heap edges in contact with humus accumulations, as is known for N. relictum (Komposch 1999; Komposch & Gruber 2004), and perhaps a humus-rich shallow subterranean habitat (SSH), i.e., Milieu Souterrain Superficiel (MSS) (Mammola et al. 2016; Halse 2018). Since this habitat is restricted to an area of less than 1 km 2 on Mt. Snežnik, this subspecies is considered highly endangered. Phenology: probably eurychronous. Hybrids among the subspecies of Nemastoma bidentatum Remarks In Austria, a few localities are known where N. b. bidentatum lives in syntopy with N. relictum (Gruber & Martens 1968; Martens 1978; in both papers sub N. b. relictum), and with N. b. sparsum (Komposch & Gruber 2004; Komposch 2009). However, individuals of these three taxa do not interbreed and have been considered as potential species (Gruber & Martens 1968; Martens 1978; Komposch & Gruber 2004; Komposch 2009). In Slovenia, N. b. schmidti ssp. nov., with its central geographic position, interbreeds with all other adjacent subspecies: N. b. bidentatum in the North, and N. b. martensi ssp. nov., N. b. sneznikensis ssp. nov., N. b. gruberi ssp. nov. and N. b. sparsum from the Southwest to the Northeast of the country. Besides, N. b. gruberi ssp. nov. interbreed with N. b. martensi ssp. nov., and with N. b. sparsum. In Bosnia, N. pluridentatum stat. nov. has not been found; consequently, the genitalia have not been examined. Despite this, major differences from all the other known taxa within the N. b. complex allow it to be considered a separate species. This is because interbreeding of N. pluridentatum stat. nov., which might be a subalpine species, with the montane N. kozari sp. nov. from the same mountain is quite unlikely, given their great dissimilarity. However, data on taxa of Nemastoma in Bosnia and Herzegovina are nearly completely missing, allowing no further conclusions. Although being morphologically variable, hybrids possess larger Ch-Apo than pure subspecies and are well distinguishable from these. In interbreeding subspecies, hybrids between the two subspecies frequently occur syntopically with individuals belonging to pure subspecies. Consequently, such a collection consists of either one or two pure subspecies and a series of hybrids with varying Ch-Apo shapes. An overview of interbreeding relations among the taxa of the N. b. complex is presented in Table 13. In Slovenia, N. b. bidentatum and N. b. sparsum do not interbreed, since the areas are several tens of kilometres distant from each other. In contrast, we have found hybrids between all the adjacent subspecies (Fig. 3), except N. b. gruberi ssp. nov. �� N. b. schmidti ssp. nov. �� N. b. sparsum, which is expected in the meeting area of the three taxa. Besides, data on hybridization of N. b. sneznikensis ssp. nov. are too scarce to be properly evaluated in full. The zone of hybridization between N. b. schmidti ssp. nov. and N. b. sparsum is the widest, measuring up to 100 km in north-eastern Slovenia, while these zones are narrow to virtually non-identifiable among the others, and hybrids are accordingly scarce. Hybrids N. b. gruberi ssp. nov. �� N. b. schmidti ssp. nov. were found in a zone up to 10 km wide, while N. b. martensi ssp. nov. �� N. b. schmidti ssp. nov. and N. b. gruberi ssp. nov. �� N. b. martensi ssp. nov. are limited to zones a few kilometers wide. In Slovenia, there are no hybrids between allopatric N. b. martensi ssp. nov. and N. b. sparsum, while these are expected in Croatia. Hybridization patterns were not simple clines in the transition zones between two subspecies. Instead, in some cases, morphologically various hybrids between the neighboring subspecies, sharing various ratios of the hybridizing subspecies characters (cf. Gruber & Martens 1968; Martens 1978), appeared scattered across the whole width of the transition zone. In some places in the hybridization zone, individuals of both subspecies, together with hybrids of various intermittent stages, occurred syntopically., Published as part of Novak, Tone, Novak, Ljuba Slana, Kozel, Peter, Schaider, Miriam Gudrun, Komposch, Christian, Lipov��ek, Sa��ka, Podlesnik, Jan, Pau��i��, Igor & Raspotnig, G��nther, 2021, Hidden diversity within the Nemastoma bidentatum Roewer, 1914 complex (Opiliones: Nemastomatidae) Part I: Morphological evidence, pp. 1-67 in European Journal of Taxonomy 777 on pages 40-42, DOI: 10.5852/ejt.2021.777.1561, http://zenodo.org/record/5637112, {"references":["Komposch C. 1999.

Diagnosis Relatively long-legged subspecies of Nemastoma bidentatum, with strait Ch ventral margin, and Pa-Fe with either 4 subequidistantly positioned spines or pointed tubercles or long setae on low protrusions, or their combination in the distal Pa-Fe half, or alternatively, with 2–3 distal stout thorns. Rec sem with one tubular and 12 elongated balloon-like vesicles. Etymology The subspecies name ʻ gruberi ʼ is dedicated to Jürgen Gruber (Vienna), our teacher, colleague and friend, who generously introduced us to the taxonomy of harvestmen and helped in identifying problematic specimens.

Remarks To date, N. b. schmidti ssp. nov. has been reported under N. b. bidentatum, and N. b. gruberi ssp. nov. under N. b. sparsum. Since hybrids N. b. bidentatum × N. b. sparsum have not been identified in any locality, all these published data likely refer either to N. b. schmidti ssp. nov. × N. b. sparsum or N. b. gruberi ssp. nov. × N. b. schmidti ssp. nov. Nemastoma b. bidentatum referred from Germany (Schönhofer & Holle 2007) is a hybrid, probably N. b. schmidti ssp. nov. × N. b. sparsum. Since both N. b. sparsum and N. b. gruberi ssp. nov. inhabit the lowland in Croatia, hybrids south of the Sava River or nearby probably belong to N. b. gruberi ssp. nov. × N. b. schmidti ssp. nov.

While the chemistries of scent gland secretions from a few selected species of three families of Cyphophthalmi, namely Sironidae, Pettalidae, and Stylocellidae, have already been reported and found to consist of complex blends of naphthoquinones and methyl ketones, nothing is known about the other families. We here report on the secretions of Metasiro savannahensis Clouse and Wheeler (Zootaxa 3814:177–201, 2014), a first representative of the family Neogoveidae. The secretions from males, females and one juvenile were extracted and analyzed by gas chromatography–mass spectrometry. Twenty-five compounds were identified, all of which belong to the chemical classes of naphthoquinones and methyl ketones, confirming a hypothesized chemical uniformity of cyphophthalmid exudates. One major naphthoquinone compound, however, was new for cyphophthalmids and for arthropod exocrine secretions in general: a methyljuglone isomer, 6-methyljuglone (= 6-MJ; iupac name: 5-hydroxy-6-methyl-1,4-naphthoquinone), amounted for about 20% of the secretion and was eventually identified by synthesis. Hydroxy-naphthoquinones and their derivatives are known to possess a variety of antibiotic effects, probably enhancing the antimicrobial/antifungal potential of the Metasiro-secretion. Currently, without further data on neogoveids, the compound represents a chemical autapomorphy of M. savannahensis, and—just as the strange chloro-naphthoquinones of Sironidae and Pettalidae—adds to the repertoire of unusual naphthoquinone compounds across the Cyphophthalmi.
