B83F87B7C85053709BE0CDD8FD1E27C2.taxon	description	Description General Small cylindrical nematodes, sexually dimorphic, males approximately one-third length of female. Lateral alae present in males, absent in females. Caudal alae absent in males (Figuere 3 (a )). Anterior extremity tapered, mouth opening triangular with three simple lips, a pair of amphids located on ventrolateral lips, and absent sessile papillae in both sexes (Figure 3 (b )). Male (one holotype) Length (excluding tail filament) 1036 ± 143 µm (896 − 1161); width at level of excretory pore 101 ± 25 (75 − 134); cuticle with distinct transverse pseudo-annulations; lateral alae starting at level of nerve ring and disappearing at level of first ventral pair of precloacal papillae; longitudinal striations absent; oesophagus length 210 ± 30 (165 − 227): corpus length 155 ± 26 (116 − 174); isthmus length 9; bulb length 57 ± 7 (46 − 63); bulb width 63 ± 11 (47 − 70); nerve ring 60 ± 5 (54 − 64) and excretory pore 306 from anterior end, respectively; spicule absent; smooth cloacal lips; caudal alae absent; four pairs of mammiliform papillae: one precloacal ventrally directed, two postcloacal ventrally directed, and one at base of filament tail (Figures 2 (g) and 4 (b )). Tail filament 216 ± 70 (117 − 275) in length, with 3 – 9 spines (Table 1). Female (nine paratypes) Length (excluding tail filament) 3007 ± 966 µm (677 − 3668); width at level of excretory pore 144 ± 29 (76 − 167); oesophagus length 479 ± 52 (373 − 531): corpus length 370 ± 32 (306 − 414); isthmus length 10; bulb length 103 ± 20 (64 − 124); bulb width 114 ± 22 (74 − 142); nerve ring 107 ± 28 (63 − 130) and excretory pore 168 from anterior end, respectively. Prebulbar vulva near mouth 158 ± 46 (61 − 206) from anterior end. Amphidelphic reproductive apparatus, vagina gives rise to two uteri. Thick-walled muscular ovijector extending posteriorly to join a valved, thin-walled, dilated vagina (Figure 2 (b )). In gravid females, the extent of the uteri cannot be seen; in immature females, one uterus extends anteriorly, the other posteriorly. Anus 231 ± 152 (67 − 366) anterior of tail filament insertion; tail filament 577 ± 136 (291 − 731) in length, 18 – 51 small cuticular spines present (Figure 3 (c) and Figure 4 (c )). Fusiform eggs with both ends rounded, length 114 ± 6 (102 − 124), width 37 ± 8 (19 − 49); Eggs in initial cleavage. Eggs with smooth surfaces and numerous inside uterus. As the number of eggs increases, the intestine is not visualised (Table 1).	en	De Sousa, Charles, Silva De Oliveira, Samanta, Morais, Drausio Honorio, Da Silva Pinheiro, Raul Henrique, Ávila, Robson Waldemar (2022): A new species of Skrjabinodon (Oxyuroidea: Pharyngodonidae) infecting Vanzosaura multiscutata (Squamata: Gymnophthalmidae) from Northeastern Brazil.
