This contribution is the first part of a series designed to summarize the present knowledge on the fauna of true bugs (Hemiptera: Heteroptera) of the Socotra Archipelago. A review of aquatic, semiaquatic and shore bugs of the infraorders Nepomorpha, Gerromorpha, and Leptopodomorpha of Socotra is provided. Nine families and 19 species are recorded from the Socotra Island (including two marine off-shore species). The following new species and new records are given: Micronecta eupompe Hutchinson, 1930 (Micronectidae), Sigara hoggarica Poisson, 1929 (Corixidae), Hebrus kanyukovae sp. nov., Hebrus sp. (Hebridae), Microvelia gracillima Reuter, 1882, M. macani Brown, 1953 (Veliidae), Limnogonus cereiventris (Signoret, 1862) (Gerridae), Micracanthia ornatula (Reuter, 1881), and Saldula niveolimbata (Reuter, 1900) (Saldidae). The following new faunistic records are also provided: Micronecta eupompe from Burkina Faso, Anisops varius from Jordan and Rwanda, Mesovelia vittigera Horváth, 1895 (Mesoveliidae) from Mali, Micracanthia ornatula from Guinea-Bissau, Mali, Zambia, China (Sichuan), and Bangladesh, and Saldula niveolimbata from Mali. The status of the type specimens is discussed and corrected for Anisops varius var. scutellata Fieber, 1851 (syntypes), Anisops varius var. sugillata Fieber, 1851 (lectotype), Anisops hoggarica Poisson, 1929 (syntypes), Halobates germanus White, 1883 (lectotype), Halobates sewelli Imms, 1936 (lectotype), Limnogous leptocerus (Reuter, 1882) (lectotype), and Microvelia gracillima Reuter, 1882 (holotype versus neotype).

Diagnosis. Tuponia hippophaes, the type species of the subgenus Chlorotuponia, is recognized by the following combination of characters: dorsally uniformly green (Fig. 1A) or with minute green round spots, with paler whitish areas along anterior four fifths of exocorium, inner angle of corium and basal margin of cuneus; body length 2.0– 3.4 mm in males, 2.0– 2.9 mm in females (in Romanian specimens: 2.6–3.0 mm in males, 2.3–2.6 mm in females); body elongate with parallel sides in males, more ovate in females; ocular index 1.1–1.8 in males, 2.4–3.0 in females; labium reaching between meso- and metacoxae or slightly surpassing the latter; male genitalia (Figs. 2A–E): parameres and phallotheca not surpassing apex of genital capsule (Fig. 2A); right paramere (Fig. 2B) short, ovoid, apically truncate; left paramere (Fig. 2C) with short, pointed sensory lobe and very elongate apical process; phallotheca (Fig. 2D) apically straight; vesica (Figs. 2E–F) J-shaped, with secondary gonopore in subapical position and with three apical processes, one very elongate, lanceolate, distinctly surpassing apex, the other two finger-like, shorter, slightly surpassing apex. Carapezza (1997) studied the clinal variability of the three apical vesical processes in the whole geographic range of the species; in Romanian specimens their relative lengths correspond to the arrangement commonly found in Balkan Peninsula. Similar in color pattern to T. prasina but differing from it in the more elongate body, brighter dorsal green, tibial spines not arising from basal dark dots, lower ocular index, genital capsule (Fig. 2A) apically distinctly bending to the right, differently shaped parameres, vesica with well sclerotized secondary gonopore and sclerotized apical blades. Distribution and biology. Holomediterranean element, widely distributed in Southern Europe, North Africa and Middle East, including Iran; in the last twenty years its original range, which included also the area of the Alps in Central Europe (southern Germany, Switzerland) has extended northwards to Central and Northern Europe (Belgium, Czech Republic, Slovakia, United Kingdom), probably as a consequence of global warming and of the increased popularity of Tamarix, extensively introduced as ornamental plants along the coasts and in inland gardens of Central and North European countries (Bryja & Kment 2002; Rabitsch 2002; Baugnée & Chérot 2004; Kment 2004; Telfer 2019). The species lives on Myricaria germanica, Reaumuria vermiculata and various species of Tamarix (Tamaricaceae) (Hoberlandt 1956; Tamanini 1964; Wagner 1975; Drapolyuk 1982; Carapezza, 1997; Linnavuori 2010). In Romania, based on available data so far, T. hippophaes is the single species of the genus still active at the end of summer. The presence of adults over the span of four months (June–September) indicates that the species is probably bi- or multivoltine in Romania. Discussion. This is the first record for Romania. Distribution in Romania is shown in Fig. 3. Considering that our survey revealed that T. hippophaes is the most widespread and commonest Tuponia species in Romania, it is rather surprising that it had never been recorded from the country. A possible explanation is that in the past it was overlooked and misidentified as T. prasina, on the wrong assumption that all green Tuponia in Romania belonged to that species. An alternative explanation could be that T. hippophaes has reached Romania recently, either by natural range expansion or accidental introduction., Published as part of Carapezza, Attilio & Rădac, Ioan Alexandru, 2021, The genus Tuponia Reuter, 1875 in Romania, with two new synonymies (Heteroptera: Miridae), pp. 59-76 in Zootaxa 5023 (1) on pages 61-62, DOI: 10.11646/zootaxa.5023.1.3, http://zenodo.org/record/5225491, {"references":["Fieber, F.

Tuponia (Tuponia) arcufera Reuter, 1879 (Figs. 4A, 5 A–G, 9) Material examined: ROMANIA: Buzău County: Policiori, 45.341594°N 26.665040°E, 20.vi.2017, 1 ♂ 6 ♀♀, on Tamarix sp.; Vrancea County: Focșani, 45.744303°N 27.201451°E, 22.vii.2019, 1 ♂, on Tamarix sp. Diagnosis. Tuponia arcufera is recognized by the following combination of characters: dorsally (Fig. 4A) whitish-yellow with more or less intense orange areas in mesoscutum, anterior part of scutellum, and sometimes with a large transverse band across apices of clavus and corium; body length 2.8–3.8 mm in males, 3.5–4.0 mm in females; body elongate ovate in both sexes; ocular index 1.4–1.6 in males, 1.7–1.9 in females; male genitalia (Figs. 5A–G): right paramere (Fig. 5A) elongate, narrow, apically truncate; left paramere (Figs. 5B–C) broad, with very small sensory lobe and pointed apical process; phallotheca (Figs. 5D–E) with subapical blunt tooth and two preapical vaguely semicircular lamellate keels; vesica (Figs. 5F–G) with subapical secondary gonopore located at the bifurcation of the two apical processes, the lower one strongly sclerotized, lanceolate, shorter than the upper one, the latter mostly membranous, equipped with a basal hump clothed with minute spinules and dorsally serrate. Due to the variability in dorsal color pattern of T. arcufera, specimens with weakly contrasting colors (as in Fig. 4A) are very similar to T. montandoni from which they can be distinguished only by characters of male genitalia, in particular the elongate and apically truncate right paramere, phallotheca with two preapical keels and differently shaped apical part of vesica (this can be appreciated comparing figs. 5F–G and 8F–G). Distribution and biology. Euro-Central Asian element known from Spain, southern France, northern Italy, Macedonia, Bulgaria, Moldavia, Ukraine, south of European Russia, Turkey, Transcaucasia, Iran, Central Asia, Mongolia, north-western and north-eastern China (Kerzhner & Josifov 1999; Konstantinov 2016; Aukema 2018– 2021).

Notes. GUÉRIN- MÉNEVILLE (1843) dedicated the species to its collector, M. Perbosc, using the latinized form of his name (Perboscius, stem perbosci -) to form the name as O. perboscii, which is the correct original spelling of the name. The name was cited as O. perboscii at least five times (for references see above) until KIRKALDY & TORRE BUENO (1909), with a single exception of CHAMPION (1901). CHAMPION (1901), MONTANDON (1910), and all subsequent authors (for 27 additional references see above) used the incorrect subsequent spelling of the name, O. perbosci (see ICZN 1999: Art. 32.1–3, 33.3, 33.4). In this case the Article 33.3.1 (ICZN 1999) applies in favour of O. perbosci: ‘when an incorrect subsequent spelling is in prevailing usage and is attributed to the publication of the original spelling, the subsequent spelling and attribution are to be preserved and the spelling is deemed to be a correct original spelling.’ We recognize O. perbosci as being in prevailing usage and therefore the correct original spelling in the sense of ICZN (1999). GUÉRIN- MÉNEVILLE (1843) described the species based on unknown number of specimens and without information on their depository. CHAMPION (1901) wrote that: ‘The type of this insect was obtained by us from the Sallé collection’. CIANFERONI (2012) specified the sex of the specimen, incorrectly labelled as holotype, as male. Using the term ‘the type’ for the syntype he used for definition of the taxon, CHAMPION (1901) fulfilled the requirements of the Article 74.5 (ICZN 1999) and his action constitutes a valid lectotype designation. It was also recorded from Cuba by CHAMPION (1901) and KIRKALDY & TORRE BUENO (1909) by error (see NARANJO et al. 2010, POLHEMUS & POLHEMUS 2016)., Published as part of Kment, Petr, Carapezza, Attilio & Jindra, Zdeněk, 2020, Taxonomic catalogue of the family Ochteridae with description of Ochterus papaceki sp. nov. from Socotra Island and Tanzania (Hemiptera: Heteroptera), pp. 23-64 in Acta Entomologica Musei Nationalis Pragae 60 (1) on page 45, DOI: 10.37520/aemnp.2020.003, http://zenodo.org/record/3879659, {"references":["GUERIN-MENEVILLE F.

Timms, presented by Department of Entomology, University of Queensland, Q.M. F6473’ (QMBA). Heterochterus timmsii: JELL (2004): 65 (redescription, illustrations). Distribution. Australia: Queensland (Ipswich Coal Measures: Late Triassic) (EVANS 1971, JELL 2004). Discussion The first described species of velvety shore bugs was the widely distributed Acanthia marginata Latreille, 1804, discovered in southern France, and soon after accommodated in its own new genus, Ochterus Latreille, 1807, and new family, Pelogonida Leach, 1815 (based on an unnecessary new replacement name Pelogonus Latreille, 1809). Additional two taxa were described by GUÉRIN- MÉ- NEVILLE (1843), Pelogonus indicus (junior synonym of O. marginatus marginatus) from India, and the first American species, Pelogonus perboscii from Mexico. Until the end of 19th century, altogether eleven species of Ochteridae were described, seven of which still remain valid. Among them were also two species which were in the future designated as types of new genera, Ocyochterus Drake & Gómez-Menor, 1954 (Pelogonus victor Bolívar, 1879) and Megochterus Jaczewski, 1934 (Pelogonus nasutus Montandon, 1898). Between 1901 and 1970, 17 additional species of Ochteridae were described, mostly from the American continent where important contributions were published by CHAMPION (1901), BARBER (1913), HUNGERFORD (1927), and especially the revision by SCHELL (1943a,b). In the Old World, only five species were described in this period (HORVÁTH 1913; JACZEWSKI 1934, 1935, 1938; MANCINI 1939). SINGH- PRUTHI (1925) first described and illustrated male genitalia including the right paramere of Ochterus marginatus, a character soon applied in ochterid taxonomy by HUNGERFORD (1927) and JACZEWSKI (1934). Big progress in describing new Ochteridae started in 1970s with three revisional papers by Nicolas A. Kormilev for Australian, Oriental and Afrotropical taxa (KORMILEV 1971, 1972, 1973), largely based on the structure of the right paramere. Soon followed the papers of NIESER (1975) (Suriname), POLHEMUS & POLHEMUS (1976) (SW USA), RIEGER (1977) (Australia, Philippines), and GAPUD & SAN VALENTIN (1977) (Philippines). Victor P. Gapud continued his work on the fauna of Philippines also in the following three decades (GAPUD 1981, 1995, 2003). In the same time, Martin Baehr, a renowned German coleopterist specialised in Carabidae (Coleoptera), revised Ochteridae of the Australian Region in a series of four papers (BAEHR 1989, 1990a,b,c). In 1990s, Nico Nieser and Ping-ping Chen described seven additional species mostly from Malesia, but also from southern China and South America (NIESER & CHEN 1992, 1999). Finally, Dan A. Polhemus started describing new Ochteridae with Ochterus seychellensis in 1992 (POLHEMUS 1992a), and continued, together with his father John T. Polhemus, with series of revisional papers on Ochterus of Mauritius (POLHEMUS & POLHEMUS 2008), Malaysia and the Oriental part of Indonesia (2012, 2015), North and Central America (POLHEMUS & POLHEMUS 2016), as well as a revision of the genus Ocyochterus with the description of one new species (POLHEMUS & POLHEMUS 2014). Since 1971, 64 species of Ochteridae were described, nearly three times the number described before this date (see Table 1 and Fig. 25). The most prolific authors were D. A. and J. T. Polhemus, who described together 17 species of Ochteridae, followed by M. Baehr with 16 species and subspecies, N. Nieser with 9 species, and N. A. Kormilev and V. P. Gapud each with 8 species (cf. Table 2). The species inventory of Ochteridae is certainly far from complete, as it is documented by mentions of a probable new species of Ochterus from Palawan (GAPUD 2003) and several undescribed species from New Guinea (POLHEMUS & POLHEMUS 1998, 2012), and Oriental Region, as well as due to the probable polyphyly of O. marginatus (CHEN et al. 2005). Also our unpublished results suggest existence of additional undescribed species, especially in the Oriental Region, the Afrotropical Region and Madagascar. The extant members of the family Ochteridae are distributed in the tropical and subtropical regions of all continents. The present lack of published records from Lesser Sunda and Maluku Islands (Indonesia) is probably due to sampling bias, as we have at hand unidentified material from Maluku, superficially resembling O. nicobarensis (ZJPC). Further Ochteridae inhabit temperate zones of Australia and Tasmania (ANDERSEN & WEIR 2004), East Palearctic (north to the northernmost Japanese island, Hokkaido, and to Kunashir, the southernmost island of Kuriles) (POLHEMUS 1995 a, KANYUKOVA 2006, HAYASHI et al. 2016, HAYASHI & MIYAMOTO 2018) and Eastern Nearctic Region (north to Massachusetts, Michigan, Minnesota and Ontario (POLHEMUS & POLHEMUS 1988a, 2016; MAW et al. 2000). On the contrary, Ochteridae are missing in temperate Europe, continental regions of Central Asia (POLHEMUS 1995 a, KANYUKOVA 2006), from the Appalachian Mountains and the Ozark Plateau in the eastern part, as well as from most of the western part of USA (POLHEMUS & POLHEMUS 1988a, 2016), from New Zealand, and from temperate and subtropical South America (the most southern species being O. foersteri reaching the Misiones province of Argentina – MELO 2015, BACHMANN & MAZZUCCONI 2017). The zoogeographical pattern of Gelastocoridae resembles that of Ochteridae, with three exceptions: i) Gelastocoridae in South America occur further south, into central Chile; ii) in the Eastern Palaearctic they extend northward only to central China and the southern Japanese islands of Kyushu and Shikoku; and iii) they are completely absent in the Western Palaearctic (except one record from coast of Sinai, Egypt) (e.g., TODD 1955, 1961; POLHEMUS & POLHEMUS 1988b; POLHEMUS 1995b; ANDERSEN & WEIR 2004; CHEN et al. 2005; KMENT & JINDRA 2008; FAÚNDEZ & ASHWORTH 2015; FAÚNDEZ & CARVAJAL 2017; NIESER et al. 2020). Concerning the biodiversity pattern, we can recognize two distinct biodiversity centres, the Australasian Region with 29 species-group taxa and the Neotropical Region with 28 species-group taxa. Within the Neotropical Region, most of these taxa (i.e. 17) are known from Central America, while only 14 species and subspecies are known from South America (see Table 2). This situation may be influenced by the existence of the recent excellent revision of Central American fauna by POLHEMUS & POLHEMUS (2016) and future research will elucidate the precise number of species actually occurring in South America. In the Caribbean, so far only one endemic species is known (O. hungerfordi from Cuba) and two widely distributed species shared with the continent (O. aeneifrons aeneifrons and O. perbosci), which is in contrast with high number of island endemics occurring in Malesia and islands of the Indian Ocean. In the Australian Region, 5 species occur in Sulawesi (including the widely distributed O. marginatus marginatus and O. noualhieri shared with Sundaland), 11 species in New Guinea, Vanuatu and Solomon Islands, 13 species and subspecies in Australia, and 2 species in New Caledonia (one of them endemic). The Oriental Region seems also species rich with 22 species-group taxa, but only 5 species are so far known in its western (mostly continental) part north of the border of Malaysia; 8 species occur in Sundaland and 11 species and subspecies are confined to the Philippines. The Afrotropical Region harbours 8 species, 6 of them occurring on the continent and 4 on the adjacent islands; O. caffer and O. papaceki sp. nov. occur in both the African mainland and islands (Madagascar and Socotra, respectively), while Mauritius and Seychelles each harbour a single endemic species. The fauna of the Nearctic Region includes five species (with O. rotundus and O. perbosci confined to its southernmost regions and shared with Neotropical Region) (POLHEMUS & POLHEMUS 2016). The least species rich is fauna of the Palaearctic Region, including only three described species, the widely distributed O. marginatus marginatus, O. strigicollis endemic to Israel, and O. breviculus confined to the transitional zone between the Palaearctic and the Oriental Region in Yunnan and Xizang (Tibet) in southern China (NIESER & CHEN 1992, POLHEMUS 1995a). In alternative zoogeographical regionalisation, Malesia (including the Malay Peninsula, Sundaland, Philippines, Wallacea, New Guinea and Solomon Islands), would harbour 33 species and subspecies – see CHEN et al. 2005, ZETTEL & LANE 2010. POLHEMUS & POLHEMUS 2012). In contrast to the New World, we must stress the importance of island endemism for the species diversity in Old World Ochterus – among 55 Old World species, 33 (60 %) of them are confined to islands. Interestingly, also Gelastocoridae also share a similar pattern of species richness, with centres of biodiversity in Neotropical and Australian Region; the Oriental Region harbours only 9 species, 3 of them extending to Eastern Palaearctic, the Afrotropical Region has only 2 species, one of them marginally reaching the Western Palaearctic; 8 species-group taxa occur in Nearctic Region, though most of them are confined to its southernmost areas, Florida and along the Mexican border (e.g., TODD 1955, 1961; POLHEMUS & POLHEMUS 1988b; POLHEMUS 1995b; ANDERSEN & WEIR 2004; CHEN et al. 2005; KMENT & JINDRA 2008; FAÚNDEZ & ASHWORTH 2015; NIESER et al. 2020). The phylogenetic relationships within Ochteridae were addressed by MAHNER (1993) and summarized as follows: (Megochterus + (Ocyochterus + (American Ochterus + Old World Ochterus))). The monophyly of the Old World Ochterus is well supported by the apomorphic structure of the right paramere, provided with a rounded apical cap and two subapical appendages; however, the monophyly of American Ochterus with a simple right paramere remains questionable, as their paraphyly towards the Old World clade (Ochterus s. str.) is also possible (MAHNER 1993). The first cladistic analysis of relationships among genera of Ochteridae was performed by YAO et al. (2011), who included the three recent genera and three fossil genera from Late Jurassic and Early Cretaceous of China, suggesting the following relationships: ((† Floricaudus + † Pristinochterus) + († Angulochterus + (Megochterus + (Ochterus + Ocyochterus)))). For review of the fossil taxa assigned to Ochteridae and Ochteroidea stem group see Table 3. On the other hand, relationships among species-group taxa within the diverse Ochterus have never been rigorously tested. Considering the morphological homogeneity of this group, the use of molecular phylogenetic methods will be necessary., Published as part of Kment, Petr, Carapezza, Attilio & Jindra, Zdeněk, 2020, Taxonomic catalogue of the family Ochteridae with description of Ochterus papaceki sp. nov. from Socotra Island and Tanzania (Hemiptera: Heteroptera), pp. 23-64 in Acta Entomologica Musei Nationalis Pragae 60 (1) on pages 51-55, DOI: 10.37520/aemnp.2020.003, http://zenodo.org/record/3879659, {"references":["EVANS J.

Ochterus parvus Schell, 1943 (Fig. 24) Ochterus parvus Schell, 1943a: 32, 35 (key to species, illustration). LECTOTYPE (designated by SCHELL 1943b: 40, as holotype):, Ecuador: ‘Mera’ (SEMC). Ochterus parvus: SCHELL (1943b): 39 –40 (original description, differential diagnosis); DRAKE (1952): 74 (checklist); FROESCHNER (1981): 61 (catalogue); HECKMAN (2011): 460 (key to species, illustration); CIANFERONI (2012): 67 (key to species). Material examined. ECUADOR: NAPO : 7.5 km SE of Archidona, San Pablo de Ushpayacu env., 0°56′52″S 77°45′01″W, 540 m a.s.l., 23.xi.2006, 1 ♀ (Fig. 24), M. Fikáček lgt., P. Kment det. (NMPC). Distribution. Neotropical Region: South America: Ecuador (SCHELL 1943b, DRAKE 1952, CIANFERONI 2012). Note. The revision of American Ochterus including the description of O. parvus was published divided in two parts, the first published in January 1943 (SCHELL 1943a) and the second in April 1943 (SCHELL 1943b). The species was first introduced in the key, which is sufficient to make it available (ICZN 1999: Art. 13.1.1), without any mention of type specimens (SCHELL 1943a: 32), while the original description including the holotype designation appeared in the second part (SCHELL 1943b: 39). As a holotype is defined as ‘the single specimen upon which a new nominal species-group taxon is based in the original publication’ (ICZN 1999: Art. 73.1), in this case, the subsequently designated ‘holotype’ must be considered the lectotype according to ICZN (1999: Art. 74.5). Ochterus paucistriatus Baehr, 1990 Ochterus paucistriata Baehr, 1990b: 450, 453, 454, 456–459, 461, 468 ‒469 (key to species, description, illustrations). HOLOTYPE:, Indonesia: Papua:ʻDutch New Guinea: Cyclops Mts., Mt.Lina, 3500 ft. [= 1067 m a.s.l.]’ (BMNH). Ochterus paucistriata: CHEN et al. (2005): 413 (checklist). Distribution. Australian Region: Indonesia: Papua (BAEHR 1990b, CHEN et al. 2005) Note. BAEHR (1990b) established the species name as O. paucistriata, citing it 11 times throughout the paper, but without providing any explanation of its etymology. CHEN et al. (2005) also accepted O. paucistriata as the correct original spelling. However, the species name is a compo- sed Latin adjective paucistriatus (- a, - um) and the generic name Ochterus is masculine. Therefore, we correct here the gender agreement of the name to O. paucistriatus (see ICZN 1999: Art. 31.2, 34.2)., Published as part of Kment, Petr, Carapezza, Attilio & Jindra, Zdeněk, 2020, Taxonomic catalogue of the family Ochteridae with description of Ochterus papaceki sp. nov. from Socotra Island and Tanzania (Hemiptera: Heteroptera), pp. 23-64 in Acta Entomologica Musei Nationalis Pragae 60 (1) on pages 44-45, DOI: 10.37520/aemnp.2020.003, http://zenodo.org/record/3879659, {"references":["SCHELL D.
