Diporodrilidae Bouché, 1970 This monogeneric family with three species and two subspecies was erected by Bouché (1970) for specimens collected in the Mediterranean islands of Corsica and Sardinia, from where they are endemic. Recent sampling in Corsica revealed several new lineages and species that must still be described (Marchán et al., 2022b). The validity of this family was also re-affirmed with recent molecular (Anchor-Hybrid Enrichment) analyses, which placed it as sister to the Lumbricidae (Marchán et al., 2022c)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Arecoidae James, Csuzdi & Brown, 2023 Fam. nov. Type genus: Areco Righi, Ayres & Bittencourt, 1978 Diagnosis: Crassiclitellata with quadrangular body, and dorsal post-clitellar groove. Four pairs of closelypaired, regularly distributed hook-shaped setae. Dorsal pores present. Genital pores microscopic. Long muscular esophagus, but no gizzard. No calciferous glands, no prostates or copulatory pouches. Intestine begins in XXXVII, typhlosole present. Pretesticular spermathecae, ovaries in XIII. Moniliform hearts in segments VIII to XI. No subneural vessel. Nephridia holoic, without bladders. Metandric, with one pair of testicles and seminal funnels in segment XI. Seminal vesicles in XII to XV. Etymology: This new family name derives from the genus name Areco which with the species name reco is derived from “arecoreco”, originally in the Tupi indigenous language, meaning to confuse or to mix something up (Drumond 1952). Considerations: The intriguing aqua-megadrile (sensu Jamieson 1988) species Areco reco was described by Righi et al. (1978) from four specimens collected at the Reserva Ducke near Manaus, Amazonas (Brazil) in 1975. Type specimens are deposited in the Instituto Nacional de Pesquisas da Amazonia (INPA) collection in Manaus. The authors placed the species tentatively in Sparganophilidae, but emphasized that the exact position of Areco was uncertain. They claimed similarity with Glyphydrilocrius by shape of body and organization of digestive system, and with Sparganophilus by presence of pretesticular spermathecae, though this is a feature shared with several other South American families (e.g., Glossoscolecidae, Rhinodrilidae). Furthermore, Sparganophilus and Glyphydrilocrius are holandric, while Areco is metandric. Additional Areco specimens were collected at the type locality by S. James and S. Tapia-Coral in 2012 (Erséus et al. 2020), and molecular phylogenomic analyses revealed it to be sister to Rhinodrilidae, and far from Sparganophilidae and other semi-aquatic families (Erséus et al. 2020). Nonetheless, Arecoidae shows important genetic divergence and major morphological differences with Rhinodrilidae, lacking gizzard and calciferous glands, so we propose here the erection of this new monotypic family to accommodate its only species and genus., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Acanthodrilidae Claus, 1880 The Acanthodrilidae is the second most speciose earthworm family – 746 species and 48 subspecies in 68 genera. Csuzdi (1996) divided it into three subfamilies: Acanthodrilinae, Octochaetinae and Benhamiinae, but the molecular work of James and Davidson (2012) provided evidence that suggested raising the Behamiinae to family level (Benhamiidae). Hence, we consider Benhamiidae as a separate family here. Diplocardinae Michaelsen 1899 has been proposed, but differently defined. The African, Central and South American, and Austral-Asian octochaetine worms surely belong to Acanthodrilinae (Buckley et al. 2011; James & Davidson 2012). Various other subfamilies were proposed by Blakemore (2013), but to date there has been limited acceptance of these subfamilies due to unresolved taxonomic issues and disagreement, and pending further molecular work within the Acanthodrilidae (see Fragoso & Rojas 2016, 2019). The endemic taxa of Acanthodrilinae can be found throughout the southern continents (South America, South Africa, Madagascar, Australia, New Zealand, New Caledonia and the Antarctic Islands), as well as in the USA, Mexico and the Caribbean Islands (Fragoso & Rojas 2016, 2019; Buckley et al. 2011). However, they are completely missing from Europe and the Northern part of Asia (the Palearctic Region). This widely distributed Gondwanan subfamily includes 41 genera and ca. 580 species (updated from Fragoso & Rojas 2016). From continental Central America and the Caribbean Islands and Mexico, we know 14 genera (Balanteodrilus, Borgesia, Diplocardia, Diplotrema, Exxus, Kaxdrilus, Larsonidrilus, Lavellodrilus, Mayadrilus, Protozapotecia, Neotrigaster, Trigaster, Zapatadrilus, Zapotecia) and around 120 species (Fragoso & Rojas 2016, 2018, 2019; Cervantes et al. 2016). Further endemic genera are found in Eastern African countries and in Madagascar (Howascolex and Vazimbascolex, with four and one species, respectively; Csuzdi et al. 2016; Hong et al. 2019). In USA and Mexico there are over 50 species of Diplocardia, and in Mexico, the following additional native genera can be found: Balanteodrilus (3 species), Diplotrema (6 species), Kaxdrilus (3 species), Larsonidrilus (2 species), Lavellodrilus (3 species), Mayadrilus (1 species), Microscolex (3 species), Protozapotecia (4 species), and Zapotecia (2 species) (Reynolds 2020; Fragoso & Rojas 2016, updated with new species). In Central America and the Caribbean, there are the following native genera: Balanteodrilus (1 sp.), Diplotrema (4 species), Kaxdrilus (4 species), Parachilota (2 species), Protozapotecia (3 species) and Zapotecia (1 sp.), while in South America, we find mostly Chilota (26 species), Diplotrema (9 species), Microscolex (10 species) and Yagansia (21 species) in the Andean and Pampean regions of Chile and Argentina (Fragoso & Rojas 2016, 2018; Cervantes & Fragoso 2018). Exxus is of unknown provenance, but suspected to be Caribbean or Central American. In Africa, the Acanthodrilinae are distributed mainly in South Africa comprising 5 genera (Chilota, Eodriloides, Microscolex, Parachilota and Udeina) and ca. 110 species (Plisko & Nxele 2015). In Australia, native acanthodrilinae include six native genera (Diplotrema, Kayarmacia, Microscolex, Neodiplotrema, Rhododrilu s and Torresiella) and approximately 120 species (expanded from Fragoso & Rojas 2016). However, the genus Diplotrema is in need of further work (particularly molecular) within the Acanthodrilinae, which will probably end up splitting off the Neotropical species present in Mexico from those in Oceania (Fragoso & Rojas 2019). At least two Acanthodrilinae species – Microscolex dubius (Fletcher), and M. phosphoreus (Dugés), probably originally from Southern South America (Argentina) – are cosmopolitan, although they tend to be more common in subtropical and temperate climate regions (Rota et al. 2018b). These species were described from specimens collected outside their native range, and have been widely reported from North American and European countries (e.g., Portugal, Spain, France, Italy, Hungary, Serbia, Bulgaria, Albania and Greece), Australia, New Zealand and South Africa. The species M. phosphoreus is a well-known widespread bioluminescent worm, but recent work has shown the need for more detailed analysis of its taxonomy (both morphology and genetics) and questioned the identity of samples deposited throughout the world, due to the presence of cryptic morphs that may be different species (Rota et al. 2018b). However, this high morphological plasticity and deep genetic differentiation can also be due to its well-known parthenogenetic reproduction mode (as in many peregrine species) (Gates 1972)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Biwadrilidae Jamieson, 1971 This monogeneric family includes only one species, Biwadrilus bathybates (Stephenson), known only from the Lake Biwa region in Japan. It was originally described as a Criodrilus species, and Blakemore (2008b) transferred it back to Criodrilidae based on new material and re-analysis of previously observed material. However, molecular analysis shows this family solidly placed as the sister family to Kynotidae, and therefore quite distant phylogenetically from the Criodrilidae (James & Davidson 2012), hence we maintain it within Biwadrilidae, following Jamieson (1971, 1988)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Moniligastridae Claus, 1880 Although moniligastrids are not considered part of the Crassiclitellata since their clitella have only a single layer like the Enchytraeidae, they tend to have much larger individual body size and mass than enchytraeids and are phylogenetically sister to the Crassiclitellata (James & Davidson 2012; Schmelz et al. 2021). The family is mainly distributed in the Oriental region from south India east to the Philippines and north to southern Siberia and Japan (Gates 1972; Perel 1997). It includes 185 species (and 19 subspecies), distributed among five genera (Desmogaster, Drawida, Eupolygaster, Hastirogaster, Moniligaster), of which Drawida is the most widely distributed and speciose (162 spp./sspp.). Three species, Drawida barwelli (Beddard), Drawida japonica (Michaelsen), and Drawida nepalensis Michaelsen, are cosmopolitan, but of these, D. barwelli is the most widely distributed. It is also sometimes mentioned under its synonymous names D. bahamensis (Beddard), or D. beddardi (Rosa), being reported from Africa (Csuzdi 2005), Australia, South-East Asia, Mexico, Central America, the Caribbean, and several Pacific Islands (Blakemore et al. 2014; Csuzdi et al. 2017)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Benhamiidae Michaelsen, 1897 Native species of the Benhamiidae (351 species and 6 subspecies in 20 genera) are mainly restricted to subSaharan Africa, Oceania, Central America and northern South America (Csuzdi 2010). However, a few Dichogaster (including the type species of the genus) are also known from the Pacific islands of Fiji and Samoa (Easton 1984; James & Davidson 2012). In Africa, the native Benhamiidae are present mainly in the tropical region with 16 genera (Afrogaster, Agastrodrilus, Benhamia, Benhamiona, Dichogaster, Dudichiodrilus, Guineoscolex, Loksaia, Millsonia, Monogaster, Monothecodrilus, Omodeona, Pickfordia, Pickfordiella, Reginaldia and Wegeneriella) and ca. 250 species. From the Neotropics, i.e., the Caribbean islands, Central America, Mexico, and Northern South America we know five genera (Dichogaster, Eutrigaster, Neogaster, Omodeoscolex, and Wegeneriona) and around 100 species, mainly of Dichogaster and Eutrigaster, many of which show high endemism rates, particularly on the Caribbean islands. The diversity of the minute South-American species is certainly underestimated due to a lack of sampling, especially in Amazonia, where recent work (in French Guyana), revealed several new species, that are presently being described. Several species in the family Benhamiidae, particularly in the genus Dichogaster, are widespread anthropochores in the tropics, as their native ranges were probably originally in Central and Eastern Africa (Gates 1972; Csuzdi 2010). These species were probably widely dispersed during the centuries of commercial product exchanges between Africa and other continents, where ships could have transported soil in planted pots containing these generally parthenogenetic species. More recent transport with manure piles or agricultural equipment may also have led to the abundance of Dichogaster gracilis (Michaelsen), Dichogaster bolaui (Michaelsen), Dichogaster saliens (Beddard), and Dichogaster affinis (Michaelsen) in many no-tillage sites in Southern and Central Brazil, where they may reach abundances well over 100 individuals m-2 (Bartz et al. 2009; Bartz et al. 2014; Santos et al. 2018). Although Dichogaster spp. are generally restricted to warm and humid tropical regions, several species have been reported from greenhouses in temperate climates and at least one species (D. bolaui) was considered a domicole (adapted to human homes) species, as it was found in bathtubs, showers and sewage pipes in Hungary, Ireland, Finland, Sweden and Israel (Terhivuo 1991; Erséus et al. 1994; Rota & Schmidt 2006; Csuzdi et al. 2008). In fact, the type locality of D. bolaui is Hamburg, where it was found in fermenting bark at a factory (Michaelsen 1891). Dichogaster annae (Horst) is an epigeic species, common in vermicomposting ventures in tropical countries such as Brazil (James & Guimar„es 2010), but its distribution is probably much wider than presently known or reported, due to the lack of recognition by worm composters, and the little knowledge of its life-cycle and biology. Dichogaster modiglianii (Rosa) is an epi-endogeic species also with wide distribution (Africa, Southeast Asia, Australia, Oceania, Central America, Caribbean, Southern North America (Blakemore 2010), and was recently found in several Amazonian sites, associated with Pre-Columbian human activities (Conrado 2018). Specimens of D. bolaui were also recently reported from a remote and human-free Amazonian rainforest area in Southern French Guyana, highlighting the potential of these cosmopolitan species to establish stable populations that persist centuries after original introduction by humans (Maggia et al. 2021)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Glossoscolecidae Michaelsen, 1900 In its more restricted sense, after the splitting up of the Rhinodrilidae by James (2012), the Glossoscolecidae family is distributed mainly in continental Central and South America from Panama to Northern Argentina and Uruguay. The first species described from Latin America belongs to this family, Glossoscolex giganteus Leuckart, a large earthworm from Southeastern Brazil. In fact, the genus contains a relatively large proportion of large-bodied (> 30 cm long) species (18 out of 58 known species; Feijoo & Brown 2023). So far, native species are known in the Caribbean Islands only from Guadeloupe (James & Gamiette 2016), but they may likely occur on other islands. The family includes six genera (Enantiodrilus, Fimoscolex, Glossodrilus, Glossoscolex, Holoscolex, and Righiodrilus) and 156 species (plus 9 subspecies). One widespread species, Enantiodrilus borellii Cognetti (with which both Diaguita species, D. vivianae Righi and D. michaelseni Cordero were synonymized by Moreno et al. 2005) may constitute a potentially invasive species in the tropics, considering its distribution from Argentina to Venezuela (Fragoso & Brown 2007). As the family occurs in a region with high endemicity (Lavelle & Lapied 2003), there is a large potential to find many new species and possibly genera, with further sampling efforts, particularly in the Andean region and Northern South America, but also in the Atlantic Forest region of Southeastern Brazil (Silva et al. 2017)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Rhinodrilidae Benham, 1890 Recent changes in classification (James & Davidson 2012) moved many genera from Glossoscolecidae to Rhinodrilidae (James 2012). This family now includes 38 genera and some 376 species (plus seven subspecies) including one widespread invasive species, Pontoscolex corethrurus (M̧ller), probably the most widely distributed earthworm in the world (James 2011; Taheri et al. 2018b). Native species of this family occur from Argentina (Mischis 2007) up to Mexico (Fragoso & Rojas 2014), including several on Caribbean Islands (Rodríguez et al. 2007), although none are known from Chile (Zicsi & Csuzdi 2007). Studies on the genetic diversity of several Pontoscolex species highlighted the importance of proper identification of P. corethrurus, requiring at least barcoding, to certify species status (Taheri et al. 2018a). Species belonging to P. corethrurus must conform to the genetic lineage L1, as identified in Taheri et al. (2018a) and James et al. (2019). The genus Martiodrilus with 88 known species and subspecies is the most speciose, occurring from Panama in the north to Peru in the south, and to French Guyana in the east (Fragoso & Brown 2007), with a large number of species still to be found with additional sampling efforts in Amazonia and the Andes region. The following other speciose Rhinodrilidae genera by decreasing order of species richness are: Rhinodrilus (52 spp./sspp.), Andiorrhinus (48 spp./sspp.) and Andiodrilus (40 spp./sspp.). Together with Rhinodrilus, Martiodrilus is also remarkable for the presence of several very large-bodied earthworm species (Brown & James 2007; Zicsi 2007). One other widespread species of Rhinodrilidae is worth mentioning here: Urobenus brasiliensis Benham, found in Paraguay (Brown & Fragoso, 2007) and in Brazil from Manaus in the Amazon (R̂mbke et al. 1999; Zicsi et al. 2001) to Pelotas in the Pampa biome (Santos et al. 2019). This cryptic species requires further morphological and molecular work in order to separate the many genetic lineages that have little morphological differentiation (da Silva et al. 2017). Furthermore, the genus Alexidrilus Righi, was recently synonymized with Urobenus Benham, and its two species, A. lourdesae Righi and A. littoralis Ljungstr ̂m, with U. brasiliensis (Ferreira et al. 2023)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Ocnerodrilidae Beddard, 1891 The widespread Ocnerodrilidae family, with 37 genera and 172 species (plus four subspecies), sister taxon to the Megascolecidae + Acanthodrilidae s.l. clade (James & Davidson 2012), was last reviewed by Fragoso & Rojas (2009) and Hernández-García et al. (2018), who provided keys to the genera known until then.Two sub-families (Ocnerodrilinae and Malabariinae) were proposed by Gates (1966) and their definitions expanded by Gates (1972) and Fragoso and Rojas (2009). Ocnerodrilinae is more speciose and wider spread, while Malabariinae includes species only from India, China and Myanmar (Fragoso & Rojas 2009), without extramural glands and internal calciferous lamellae. With the exception of several peregrine species with worldwide distribution, all endemic genera and species of Ocnerodrilinae are confined to South and Central America, sub-Saharan Africa, India (Curgiona), and the Seychelles (Maheina). A large number of new species and several new genera were recently found in Brazil (James et al. 2023; HernándezGarcía et al. 2018), and it is likely that further sampling particularly in Northern South America, and in Brazil’s Northeastern region will reveal many more. The majority (27) of the known genera occur in Latin America, while nine genera are known from Africa and five from Asia (India, China and Myanmar). In Latin America, many of the smaller and pigmented ocnerodriles, particularly in the genera Kerriona and Eukerria inhabit wetlands or bromeliads, and some of them are quite resistant to disturbance, being present in intensively plowed rice or no-tillage row-crop fields in Southern Brazil (Bartz et al. 2013; Bartz et al. 2014; Ferreira et al. 2023; Lima & Rodríguez 2007). There are nine widespread anthropochorous ocnerodriles: Eukerria eiseniana (Rosa), Eukerria kuekenthali (Michaelsen), Eukerria saltensis (Beddard), Eukerria stagnalis (Kinberg), Gordiodrilus elegans Beddard, Gordiodrilus habessinus Michaelsen, Gordiodrilus paski Stephenson, Nematogenia lacuum Beddard, and Ocnerodrilus occidentalis Eisen, that typically live in wet or saturated soils, generally close to water sources. Some of these are of uncertain origin, being possibly of South America or Africa but, in any case, are of Gondwanan or Central Pangean origin (Fragoso & Rojas 2009). The presence of many parthenogenetic morphs in some species (e.g., O. occidentalis), has resulted in extensive synonymies which must be checked (James et al. 2023), although the use of molecular methods may help unravel some of these. The species Nematogenia panamaensis Eisen was synonymized with N. lacuum by Righi (1984a), because variations between the two species were included in a group of specimens collected at the same location in Mato Grosso do Sul, Brazil. Similar to O. occidentalis further work is warranted on these poorly known ocnerodriles, particularly using more detailed genetic methods, in order to confirm the presence of potential cryptic species (Fragoso & Rojas 2009)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Lumbricidae Rafinesque-Schmaltz, 1815 The Lumbricidae is the phylogenetically youngest family in the subclass of Oligochaeta. The family perhaps originated in the Palearctic but there is a well-supported clade native to Eastern North America. Overall, the Lumbricidae family comprises some 615 species and 74 subspecies belonging to 47 genera (Brown et al. 2023), although the lumbricid taxonomy is still controversial and not yet settled (Bouché 1972; Mršić 1991; Qiu & Bouché 1998; Csuzdi & Zicsi 2003; Domínguez et al. 2015; de Sosa et al. 2019; Marchán et al. 2022a; Marchán et al. 2022c). Around 33 cosmopolitan species of the family are widespread and often invasive in numerous regions (Blakemore 2009), such as North America, Australia, New Zealand, South Africa, Southern South America, and even in equatorial countries at higher elevation (e.g., Zicsi 2007). In North America there are both native and non-native species and genera. The native genera are Bimastos and Eisenoides with 15 and two species, respectively. There are 11 genera of non-native invasive lumbricids in North America (Fragoso & Rojas 2014; Reynolds 2020, 2022), and 10 genera of invasives in South America (Fragoso & Brown 2007). In Europe, centers of diversity of lumbricids are situated in the Pyrenees and the Balkan Peninsula, as well as in the Carpathians and the Caucasus (Kvavadze 1985, 1999; Rota & de Jong 2015). The biodiversity of the Balkans is the largest in Europe (Griffiths et al. 2004), due to the complex geological history and the specific geographical position with several biogeographical regions, each characterized by specific ecological, climatic and geomorphological conditions, as well as a great variety of habitats (Trakić et al. 2016). For the last 2 million years, repeated glaciations have destroyed the biotas of much of northern and alpine Europe, and on the major mountain ranges such as the Carpathians, Caucasus, and Pyrenees. The present European earthworm fauna consists of the survivors in unglaciated, non-permafrosted areas, and their descendants who colonized the rest of the continent after the end of the last (W̧rm or Wisconsinan) glaciation. There is no way to know how many species were driven to local or global extinction. Repeated cycles could have contributed to inrefuge speciation by changing vegetation zonation. However, the pre-Pleistocene conditions were probably adequate to support earthworm populations throughout Europe and even into the Arctic, including the North American Arctic, as subtropical vegetation fossils from the Eocene occur on Ellesmere Island (Eberle & Greenwood 2012; Francis 1991). Today, most earthworm scientists agree that the original lumbricid fauna was significantly destroyed during the glacial period in much of Europe. Today's lumbricid fauna come from various elements, differing both in their historical age and in their origins. Namely, the present faunal elements are fragments of modified fauna from the Tertiary Period, that are thought to have originated in the Paleocene or Eocene. These are species that, due to their adaptability to specific conditions, have survived to this day. Such relic species are now present in the Balkans, the Pyrenees and the Apennine peninsula, the northwestern part of Africa (Maghreb), the southern part of France, Sardinia, Corsica, the southern parts of Switzerland and the Czech Republic, Turkey and the central parts of Asia (Omodeo 1952, 1956, 1961, 1988; Bouché 1972, 1983; Mısırlıoğlu 2017; Mršić & Šapkarev 1988; Mršić 1991; Marchán et al. 2020; Marchán et al. 2022b). In addition to relic species, there are also "modern" species that are thought to have appeared in the Miocene and later. A greater expansion of new "modern" species occurred during interglacial and postglacial periods, mainly in the Holocene (Mršić 1991). On the Balkan Peninsula there are 90 endemic species with the largest share in Dendrobaena (25) and Allolobophora (20) (Trakić et al. 2016; Popovic et al. 2022), while 39 have been discovered in the basin of the Carpathians, mostly Dacian endemics. Of these, 12 species are of the genus Octodrilus whose distribution center is located in the Apuseni Mountains in the southern part of the Carpathians (Csuzdi et al. 2011). Other genera appear to be endemic from southern France to the northern Iberian Peninsula. The most speciose is presently Scherotheca with 42 species/subspecies recognized to date, though many other species are still expected to be found (e.g., eight new species were recently described from Corsica; Marchán et al. 2023a). The ecologically important Lumbricidae have been explored using various tools by numerous researchers. Despite significant molecular research, there are still many species that do not have a stable taxonomic status, most of which relate to archaic species with unique taxonomic characteristics and disjunctive distributions (Marchán et al. 2022c). Answers to some of these questions are expected in the near future, and will certainly lead to a better understanding of many concerns regarding the origin and dynamics of the development of the Lumbricidae family as a whole., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Tumakidae Righi, 1995 The monogeneric Tumakidae family has only three known species, Tumak hammeni Righi, Tumak amari Celis & Rangel-Ch., and Tumak congorum Celis & Rangel-Ch., found in relatively drier, lower-elevation forests in Central Colombia and the Caribbean region, along the Magdalena River valley (Righi 1995; Celis & Rangel-Ch. 2015). Given the relatively small amount of remaining forest fragments of its native habitat in Colombia, due primarily to agricultural expansion and pastures for cattle, further efforts are needed to ensure adequate conservation of the few species known. Additional sampling efforts are also needed to discover if there are any other species present along its potential distribution range., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Eudrilidae Claus, 1880 The Eudrilidae is a peculiar earthworm family with internal fertilisation (Clausen 1965; Sims 1969). It consists of 45 genera and 305 species (plus 21 subspecies) distributed in tropical Africa from south of the Sahara to the Kalahari Desert and northern South Africa (Sims 1987). There are only two species in the family regarded as widely introduced peregrines: Eudrilus eugeniae (Kinberg) and Hyperiodrilus africanus Beddard. The first species, commonly called the "African Nightcrawler" is widespread, found mainly in vermiculture outside its native range (West Africa) throughout the tropics and sub-tropics in Latin America, the Caribbean, Madagascar, Sri Lanka, India, Philippines, Malaysia, Indonesia, Vietnam and Australia (Blakemore 2015). Rarely has this species been found inhabiting soils (Blakemore 2015) and not compost beds, and its survival under these conditions probably requires high moisture and the presence of abundant litter, or organic resources, which are its major food source. The second species, H. africanus can also be found frequently in compost-beds and high organic content soils, but its distribution is more restricted, being known from Western (Ivory Coast, Nigeria, Gabon) and Central Africa (Congo, Democratic Republic of Congo, Angola) (Tondoh & Lavelle 2005) and Brazil (Righi 1972; Sousa et al. 2020)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Microchaetidae Michaelsen, 1900 The family Microchaetidae is closely related to the two other Microchaetoidea families Tritogeniidae and Kazimierzidae (Plisko 2013; Nxele et al. 2016), and consists of three genera (Geogenia, Microchaetus and Proandricus) and 81 species (plus six subspecies) distributed exclusively in temperate and Mediterranean Southern Africa. They are known from Northern South Africa near the vicinity of the Limpopo River down to the southern limit of the continent, in all provinces as well as in Lesotho and Swaziland (Plisko 2013). The three genera appear to have a rather geographically separate distribution, with little overlap. None of the known species have been reported outside of this rather restricted range, although Plisko (2013) predicted that Microchaetidae would also be found in Zimbabwe, Botswana and Mozambique. Interestingly, some of the longest known earthworm species in the world, including Microchaetus vernoni Plisko (measuring up to 2.6 m when alive) belong to this family, which contains a reasonably large number of giant (very large or long) earthworm species, some with over 1,000 segments, particularly in the genus Microchaetus (Plisko 1992, 2013)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Criodrilidae Vejdovský, 1884 The Palearctic family Criodrilidae includes mainly aquatic species in a single genus, Criodrilus with two valid species, C. lacuum from Europe, and C. ghianae Qiu & Bouché, from Mediterranean Algeria. The former species, may be among the longest living of earthworms, known to achieve 46 years of age when kept in aquaria (Timm 2020). The species is widely distributed in Europe and common all around the Mediterranean, with its northernmost distribution in Latvia (Smiljkov et al. 2005; Blakemore 2008b; Atanacković et al. 2013; Valchovski 2013; Mısırlıoğlu 2017; Timm 2020). Outside its native range, C. lacuum has only been reported from potted plants in Baltimore (USA) (McKey-Fender & MacNab 1953). Previous reports of this species from Brazil (Knäpper 1976; Knäpper & Porto 1979) actually refer to G. camaqua, a species of Almidae (see above, and Ferreira et al. 2023)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Hormogastridae Michaelsen, 1900 The family Hormogastridae was recently revised by Marchán et al. (2018) using an integrative approach including ecological, morphological and molecular data, and was shown to include nine genera (Ailoscolex, Boucheona, Carpetania, Diazcosinia, Hemigastrodrilus, Hormogaster, Norana, Vignysa, Xanina) and 37 species (plus three subspecies). The genus Ailoscolex, with its single known species Ailoscolex lacteospumosus Bouché, formerly in the family Ailoscolecidae was basal to all Hormogastridae but kept within the family. The genera show rather restricted distribution and little geographic overlap, with the exception of Norana with Hormogaster and Boucheona (Marchán et al. 2018). Overall, the family is restricted to Europe and Northern Africa, being found in Southern France, the Spanish Iberian Peninsula, Corsica, Sardinia, the Tuscan Archipelago, mainland Italy, Sicily, Algeria and Tunisia. So far, no Hormogastridae have been found in Portugal. Given the restricted range of most known species, the future discovery of new taxa in this family is highly probable (see Marchán et al. 2023b)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Megascolecidae Rosa, 1891 The Megascolecidae is the most speciose family of earthworms (2,208 spp. and 127 subspecies) and includes 85 genera. The most speciose genera are Amynthas (713 spp./ssp.), Metaphire (242 spp./sspp.), Pheretima (171 spp./ sspp.), and Megascolex (104 sp. /sspp.). The available molecular studies all support its monophyly and show just slight differentiation inside the family. Therefore, given the contradictory taxonomic divisions (e.g., Jamieson et al. 2002; Blakemore 2013) here we do not distinguish subordinate family rank taxa. The Megascolecidae show a predominantly Australasian distribution being most speciose in Australia (ca. 45 genera and 400 species), New Zealand (8 genera and 50 spp.), Eastern and Southeastern Asia (over 1,500 spp.) (Sims 1980; Jamieson 2000). But interestingly, the North American megascolecids seem to be basal to several modern megascolecid groups such as the Asian Amynthas and Australian Perionychella, Megascolides, and Diporochaeta (Buckley et al. 2011). These include Arctiostrotus (7 species), Argilophilus (9 species), Chetcodrilus (3 species), Kincaidodrilus (1 species), Macnabodrilus (2 species), Nephrallaxis (2 species) and Toutellus (4 species), present mostly in the Pacific Northwestern States of the United States and Southern Canada (near Vancouver), but also in California (Reynolds, 2020, 2022). At least 27 species in the genera Amynthas and Metaphire, as well as Perionyx excavatus Perrier, Pithemera bicincta (Perrier), Polypheretima elongata (Perrier), Polypheretima taprobanae (Beddard) and Pontodrilus litoralis (Grube) are probably some of the most widely distributed earthworms in the world (Blakemore, 2009). In fact, many of these species were described from specimens collected outside their native ranges in Asia: for instance, Metaphire californica (Kinberg) from San Francisco, Amynthas gracilis (Kinberg) from Rio de Janeiro, Amynthas corticis (Kinberg) from Hawaii, and P. elongata from Peru. Therefore, they had been already extensively transported by humans from Asia to other continents even before they were recorded from their home ranges. The presence of parthenogenetic morphs, and wide plasticity in terms of soil and habitat preferences in several of these species means that they are excellent invaders, particularly in subtropical, tropical and even temperate regions (Brown et al. 2006; Chang et al. 2017). Some species, such as Pi. bicincta may have been extensively transported with Polynesians that sailed throughout the Pacific Ocean, as well as in flotsam or sailing ship ballast (Blakemore 2007; James 2011). Several Amynthas and Metaphire species have invaded cold-temperate regions, including the continental USA, causing extreme alterations in the native ecosystems (Chang et al. 2021)., Published as part of Misirlioğlu, Mete, Reynolds, John Warren, Stojanović, Mirjana, Trakić, Tanja, Sekulić, Jovana, James, Samuel W., Csuzdi, Csaba, Decaëns, Thibaud, Lapied, Emmanuel, Phillips, Helen R.

Interactions between plants, insect herbivores and associated predators represent the majority of terrestrial biodiversity. Insects are vital food sources for many other organisms and provide important ecosystem functions and services including pollination, waste removal and biological control. We propose a complete and reproducible education programme to guide students to understand the importance of managing and conserving forest ecosystems in their region through the study of insect ecology and natural history. Our programme involved lectures, workshops and field surveys of insects with a group of 60 high school students in Eastern Africa (Ethiopia). It addresses the key stages of an entomological research project including: 1) general entomological knowledge and understanding the role of insects in terrestrial diversity and in ecosystem functioning and services; (2) the proposal of simple research questions including hypothesis development and evaluation using scientific literature, 3) fieldwork using different types of light traps; 4) sorting and identification of the insect orders using simple diagnostic keys and illustrated plates; 5) analysing and interpreting the results and 6) demonstrating findings to peers and a public audience. Identifying insects, exploring their natural history and understanding their functions in the field bring the students towards a better understanding and awareness of the importance of forest ecosystem conservation.
