Unfortunately, the specimens found in S. pyrocephalus could not be identified to species level because they were at the tetratiridium larval stage. Molecular analyses are needed to determinate the species identity of the larvae found in reptilian hosts, which serve as intermediate hosts (Santoro et al. 2012).</p></div>	https://treatment.plazi.org/id/75E6DEFB6A88C5E416E5C2ED64EA4B83	Public Domain	No known copyright restrictions apply.

Thubunaeinae comprises two genera Thubunaea and Physalopteroides Wu &amp; Liu, 1940, both of which are parasites of reptiles and are characterized by the absence of a cephalic ring, the presence of numerous caudal papillae, and an ornamented cuticle forming papillary plates distributed on the surface of the cauda in males (Chabaud 1975). These two genera differ from each other mainly by the symmetry of their cephalic structures; in Thubunaea these structures are symmetrical, while they are asymmetrical in Physalopteroides (Chabaud 1975). Some authors, for example Moravec et al. (1997), considered that the morphological features of Thubunaea and Physalopteroides have rarely been analysed using techniques such as SEM, and that these observations could provide detailed information to assess the validity of these two genera. However, to the best of our knowledge, SEM studies are still scarce in both genera, being available for only three species of Thubunaea (Moravec et al. 1997, Pazoki and Rahimian 2014, Ramallo et al. 2016) and two species for Physalopteroides (Elwasila 1990, Goswami et al. 2016). The specimens described in the present study show a symmetrical cephalic structure, as in Thubunaea .</p><p>Currently, 20 species of Thubunaea are considered as valid: one in the Afrotropical region, T. fitzsimonsi Ortlepp, 1931; five in the Nearctic region, T. cnemidophorus Babero &amp; Matthias, 1967, T. ctenosauri Moravec, Salgado-Maldonado &amp; Mayen-Peña, 1997, T. iguanae Telford, 1965, T. intestinalis Bursey &amp; Goldberg, 1991 and T. leiolopismae Harwood, 1932; two in the Neotropics, T. parkeri Baylis, 1926, and T. eleodori Ramallo, Goldberg, Bursey, Castillo &amp; Acosta, 2016; six in the Oriental region, T. aurangabadensis Deshmukh, 1969, T. brooki Deshmukh, 1969, T. hemidactylae Oshmarin &amp; Demshin, 1972, T. mirzai Narayan, 1941, T. singhi Deshmukh, 1969, and T. syedi Deshmukh, 1969; two in the Palearctic region, T. schukurovi Annaev, 1973 and T. smogorzhewskii Sharpilo, 1966; and four species in the Saharo-Arabian region, T. baylisi Akhtar, 1939, T. dessetae Barus &amp; Tenora, 1976, T. mobedii Pazoki &amp; Rahimian, 2014 and T. pudica Chabaud &amp; Golvan, 1957 (Ramallo et al. 2016).</p><p>Six of these species lack spicules, as is the case in T. leonregagnonae sp. n.: T. cnemidophorus, T. eleodori, T. fitzsimonsi, T. mobedii, T. parkeri and T. schukurovi (Table 3). Males of four of these species ( T. eleodori, T. fitzsimonsi, T. parkeri and T. mobedii) are larger in body length than T. leonregagnonae sp. n. (10.25-11.16, 8.5-9, 10.5, 11.4-15.4 vs 4.85-8.03 mm, respectively). In the number of papillae, pedunculate or sessile, the new species also differs from most of these six species. Thubunaea leonregagnonae sp. n. has 10-16 pedunculate papillae and 11-14 sessile papillae, T. mobedii does not have pedunculate papillae; in contrast, T. fitzsimonsi and T. parkeri lack sessile papillae, and in this latter species the number of caudal papillae is smaller (16-20) than in the present specimens (24-28) (Table 3). Thubunaea leonregagnonae sp. n. is most similar to T. cnemidophorus, T. eleodori and T. schukurovi, however, it can be distinguished from the last two species in the number of sessile papillae: T. eleodori has ten and T. schukurovi has 16, instead of 11-14 in T. leonregagnonae sp. n. Males of T. leonregagnonae sp. n. and T. cnemidophorus can be differentiated mainly by having a different oesophagus length/MTBL ratio (0.1-0.16 vs 0.26) and by the former having a smaller body width (200-300 vs 350-390).</p></div>	https://treatment.plazi.org/id/BFBAF410AB74038808582DCF82AA28C2	Public Domain	No known copyright restrictions apply.
