03E7173D3522E329FF23F6C1BD51DF1E.taxon	discussion	Remarks There are three schizomid families: Protoschizomidae, Hubbardiidae and the extinct Calcitronidae. The status of Calcitronidae as a valid family is still contradictory because the tarsomere formula of 7: 5: 4: 4 (Pierce, 1951) deviates from the general pattern of 7: 3: 3: 3 shared by Protoschizomidae, Hubbardiidae and Thelyphonida (Cokendolpher & Reddell, 1992). The presence of six tarsomeres on legI is a rare occurrence in Old and New World schizomids alike and has been interpreted as a randomly occurring malformation caused by regeneration of a limb after loss or damage (Rowland, 1973). The two Recent families for schizomids can be distinguished by 29 morphological characters (Cokendolpher & Reddell, 1992; Monjaraz-Ruedas et al., 2017). Out of these characters, only the symmetry of the tarsal spurs (symmetrical in Protoschizomidae, asymmetrical in Hubbardiidae), body size (usually between 6 and 9 mm in Protoschizomidae and ~ 3 – 6 mm in Hubbardiidae), male and female flagellum morphology and the setation of the base of the anterior process (present in Protoschizomidae, absent in Hubbardiidae) can be assessed in the amber fossils owing to fossil preservation, but all of the described fossil specimens align well with the diagnosis for Hubbardiidae. Within this family, the Megaschizominae (endemic to southern Africa) have a body size of ~ 8 mm, a row of eight or nine setae along the frontal margin of the propeltidium, and their tergites II – VII on the opisthosoma have two submarginal rows of setae, whereas Hubbardiinae are smaller and have only one row. All fossil species align with Hubbardiinae rather than with Megaschizominae. The key provides basic diagnoses for all fossil genera described from Burmese amber. As the fossil schizomids are often altered and deformed by taphonomical processes, a schizomid body plan with labelling of body parts is given in Figure 2 for a better understanding of the morphology.	en	Magnussen, Ilian De Francesco, Müller, Sandro P., Hammel, Jörg U., Kotthoff, Ulrich, Harms, Danilo (2022): Diversity of schizomids (Arachnida: Schizomida) revealed by new fossil genera and species from mid-Cretaceous Burmese amber with implications for a Gondwanan origin of the Burma Terrane.

03E7173D3522E32FFCFEF554B975DD4B.taxon	discussion	Remarks The tarsal spurs are not visible, but the specimen differs from species of Protoschizomidae by the lack of the pair of setae at the base of the anterior process and the presence of a distinct stalk at the male flagellum. It also differs from members of the Megaschizominae by having a smaller body size, the lack of eight or nine setae on its anterior process and the presence of only one pair of setae on the tergites II – VII. Therefore, it is clearly a member of subfamily Hubbardiinae. The specimen cannot be assigned to any extant genus because of its combination of characters.	en	Magnussen, Ilian De Francesco, Müller, Sandro P., Hammel, Jörg U., Kotthoff, Ulrich, Harms, Danilo (2022): Diversity of schizomids (Arachnida: Schizomida) revealed by new fossil genera and species from mid-Cretaceous Burmese amber with implications for a Gondwanan origin of the Burma Terrane.

03E7173D3528E320FCFAF139BB6EDF57.taxon	discussion	Burmese amber, and the suffix - zomus, the last letters of Schizomus. It is masculine in gender. Comparisons † Cretaceozomus is similar to Zomus Reddell & Cokendolpher, 1995, an extant genus widespread in SoutheastAsiaandOceania (Reddell & Cokendolpher, 1995; Harvey, 2001 b; Manzanilla, 2010). A secure assignment of † Cretaceozomus to the genus Zomus is not possible owing to the fact that males of Zomus are still unknown, and all specimens of † Cretaceozomus are males. Therefore, important diagnostic characters (e. g. spermathecae, male flagellum shape) cannot be compared. Until additional material becomes available, it seems premature to merge the genera Zomus and † Cretaceozomus. † Cretaceozomus is also similar to Ovozomus Harvey, 2001 b found from the Comoros to the Cook Islands, but Ovozomus has eye spots, whereas † Cretaceozomus bears corneate eyes. The male flagellum is spade shaped in Ovozomus and bulbous in † Cretaceozomus. Also, the body size range of Ovozomus is larger at 4.00 – 5.51 mm compared with 2.86 – 3.00 mm in † Cretaceozomus. † Cretaceozomus shares characters with † Annazomus, which has three pairs of setae on the propeltidium and lacks eyes (four pairs of setae and eyes present in † Cretaceozomus). In † Annazomus, the male flagellum shape is nearly rectangular with a bulbous elevation, whereas the flagellum of † Cretaceozomus has a semi-oval shape. † Cretaceozomus shares characters with † Muellerizomus, which has three pairs of setae on the propeltidium and eye spots (four pairs and corneate eyes in † Cretaceozomus). Both genera differ also in flagellum shape. † Cretaceozomus shares characters with † Muellerizomus, but the latter has a single median seta followed by three pairs of setae on the propeltidium (four pairs in † Cretaceozomus). † Muellerizomus also lacks eyes and differs in flagellum shape.

03E7173D3533E338FF7AF1EDBB94D954.taxon	discussion	Remarks Specimens of this genus show asymmetrical tarsal spurs and also differ from species of the Protoschizomidae by lack of the pair of setae at the base of the anterior process and the presence of a distinct stalk at the male flagellum. They also differ from members of Megaschizominae by having a smaller body size, lack of eight or nine setae on their anterior process and the presence of only one pair of setae on the tergites II – VII. Therefore, they are clearly members of subfamily Hubbardiinae. The specimens cannot be assigned to any extant genus because of their combination of characters.	en	Magnussen, Ilian De Francesco, Müller, Sandro P., Hammel, Jörg U., Kotthoff, Ulrich, Harms, Danilo (2022): Diversity of schizomids (Arachnida: Schizomida) revealed by new fossil genera and species from mid-Cretaceous Burmese amber with implications for a Gondwanan origin of the Burma Terrane.

03E7173D3533E338FF7AF1EDBB94D954.taxon	discussion	Comparisons † Groehnizomus has similarities to Oculozomus Reddell & Cokendolpher, 1995 from Sumatra, but Oculozomus has a larger body size range of 3.5 – 6.0 mm. Both genera also differ in the shape of the male flagellum (round-bulbous in Oculozomus; subrhomboidal in † Groehnizomus). In Oculozomus, the femur of leg IV is <2.1 times longer than deep, but ~ 2.75 – 3.40 times longer than deep in † Groehnizomus. There are also similarities to † Mesozomus, but this genus lacks a posterodorsal process, has a single median seta followed by only three pairs of setae on the propeltidium and has an oblong-oval male flagellum. For comparison with Recent genera, see the Supporting Information (Table S 1). Note In † G. oculiferans, the setation of the propeltidium is equivocal. Therefore, this character is not included in the comparison.	en	Magnussen, Ilian De Francesco, Müller, Sandro P., Hammel, Jörg U., Kotthoff, Ulrich, Harms, Danilo (2022): Diversity of schizomids (Arachnida: Schizomida) revealed by new fossil genera and species from mid-Cretaceous Burmese amber with implications for a Gondwanan origin of the Burma Terrane.

03E7173D353BE334FF70F44FBD3CDEC1.taxon	diagnosis	Diagnosis † Groehnizomus rodrigoi differs from † G. oculiferans by the state of the metapeltidium, which is divided in † G. oculiferans and entire in † G. rodrigoi. Although the state of the metapeltidium is no longer considered diagnostic at genus level (Lawrence, 1969), this character still shows great consistency within a given genus. Therefore, we consider † G. rodrigoi to be distinct from † G. oculiferans.	en	Magnussen, Ilian De Francesco, Müller, Sandro P., Hammel, Jörg U., Kotthoff, Ulrich, Harms, Danilo (2022): Diversity of schizomids (Arachnida: Schizomida) revealed by new fossil genera and species from mid-Cretaceous Burmese amber with implications for a Gondwanan origin of the Burma Terrane.

03E7173D3501E30AFF74F15ABBDCDB80.taxon	discussion	Remarks Specimens of this genus show asymmetrical tarsal spurs and also differ from species of Protoschizomidae by the lack of a pair of setae at the base of the anterior process and the presence of a distinct stalk at the male flagellum. They also differ from members of Megaschizominae by having a smaller body size, lack of eight or nine setae on their anterior process and the presence of only one pair of setae on the tergites II - VII. Therefore, they are clearly members of subfamily Hubbardiinae. The specimens cannot be assigned to any extant genus because of their combination of characters.	en	Magnussen, Ilian De Francesco, Müller, Sandro P., Hammel, Jörg U., Kotthoff, Ulrich, Harms, Danilo (2022): Diversity of schizomids (Arachnida: Schizomida) revealed by new fossil genera and species from mid-Cretaceous Burmese amber with implications for a Gondwanan origin of the Burma Terrane.
