Can you confirm these amateur observations of Phyllodactylus benedettii?
|Higher Taxa||Phyllodactylidae, Gekkota, Sauria, Squamata (lizards: geckos)|
|Synonym||Phyllodactylus benedettii RAMÍREZ-REYES & FLORES-VILLELA 2018|
Type locality: Chamela Biological Station, La Huerta, state of Jalisco (19.50 N, -105.44 W WGS84), elevation 100 m
|Reproduction||oviparous. Males of P. benedettii have an extended period of reproduction (August–March) with two peaks, one in rainy season (August–October) and another one in dry season (November–March). Reproductive behavior (courtship and mating) begins in August which coincides with the beginning of rainy season. The females produce clutches of two eggs, with up to three clutches during the breeding season, with a peak of egg production from December to March coinciding with the dry season (Ramírez-Sandoval et al. 2006).|

|Diagnosis||Diagnosis. Phyllodactylus benedettii sp. nov. is a species with the largest average size within the P. lanei complex, with a maximum SVL of 75.2 mm. Dixon (1964) established three fundamental characteristics to include species and subspecies within the P. lanei complex and differentiate them from P. tuberculosus: species of the P. lanei complex have a low number of interorbital scales (12–19), white venter and low number of scales across the snout between the third labials (does not specify range of values). Phyllodactylus benedettii shows white-yellow venter, 14.4 interorbital scales on average, and 22.3 scales across the snout between the third labials.|
Within the P. lanei complex (including insular and continental species), the only species that exceed 70 mm of SVL are P. lupitae and P. lanei, two species that are very isolated geographically. It is clearly different from the nearest species P. rupinus, which has a maximum SVL of 69.4 mm, considered as a medium size species. According to the statistical analyzes previously carried out, the combination of diagnostic morphological characters are the following (in addition to the SVL): It differs clearly from all species of Phyllodactylus as it presents 62.6 (60–69) longitudinal scales, 27 (24–30) tubercles from head to tail, 14 (11–13) interorbital scales, 29 (25–32) scales across venter, 22 (22–23) third labial–snout scales, 13 (13–14) rows of tubercles across dorsum. Although P. benedettii is very similar to P. lupitae in some meristic characters, they present differences in the morphometric space (Fig. 7). Some measures allow us to differentiate these species are the head-length and axilla- groin length: P. benedettii (17.9 mm and 28.4 mm) and P. lupitae (16.86 mm and 27.93 mm). According to Castiglia et al. (2009; 2010), the karyotypes of P. l. lanei (Tierra Colorada, Guerrero) and P. l. rupinus from Chamela, Jalisco (here named P. benedetti) are different. According to their studies P. lanei has 2n = 33–34 and FN = 40–41, while P. benedettii has 2n = 38 and FN = 38.
Phyllodactylus benedettii has fewer than 30 tubercles from head to tail (24–30, 27.4 avg.) similar to P. lupitae (27–31, 28.8 avg.), P. paucituberculatus (28.7), P. kropotkini (25–31, 28.4 avg.) and P. rupinus (26–30, 28 avg.); other species have more than 30 tubercles from head to tail on average: P. lanei (32–34, 33.2 avg.), P. isabelae (30– 35, 32.2 avg.), P. t. magnus (35–40, 37 avg.), P. muralis (30–40, 33 avg.) and P. tuberculosus (33–41, 36.4 avg.). Phyllodactylus benedettii showed 62 longitudinal ventral scales (LVS) on average (60–69), other values were P. isabelae (52–58, 56.2 avg.), P. lupitae (60–64, 61.8 avg.), P. lanei (60–74, 66 avg.), P. rupinus (56–67, 63 avg.), P. kropotkini (63–73, 67 avg.), P. t. magnus (52–58, 54 avg.), P. muralis (57–61, 59 avg.) and P. tuberculosus (51–64, 57 avg.). Phyllodactylus benedettii presents 14.4 interorbital scales similar to P. kropotkini (14–16, 14.6 avg.) and differs from P. isabelae (14–20, 15.1 avg.), P. lupitae (14–20, 16.8 avg.), P. lanei (15–17, 15.5 avg.), P. rupinus (14–17, 15.5 avg.), P. t. magnus (21–23, 23.3 avg.), P. muralis (21–27, 23.2 avg.), and P. tuberculosus (16–22, 19.2 avg.). Phyllodactylus benedettii presents 29 scales across venter and differs from P. isabelae (26–29, 27.8 avg.), P. lupitae (26–29, 24.6 avg.), P. lanei (29–32, 30 avg.), P. rupinus (24–28, 26.5 avg.), P. kropotkini (29–33, 30.6 avg.), P. t. magnus (26–29, 27.3 avg.), P. muralis (33) and P. tuberculosus (27–33, 30.2 avg.). Phyllodactylus benedettii presents 22 third labial–snout scales on average (22–23) and differs from P. isabelae (19–24, 21.4 avg.), P. lupitae (23–28, 25.5 avg.), P. lanei (20–23, 21.2 avg.), P. rupinus (18–22, 20.6 avg.), P. kropotkini (19–21, 20.2 avg.), P. t. magnus (24–26, 24.6 avg.), P. muralis (24–28, 25.2 avg.) and P. tuberculosus (21–26, 24.2 avg.). Phyllodactylus benedettii presents 13.8 rows of tubercles across dorsum on average (13–14) and differs from P. isabelae (15–18, 16.7 avg.), P. lupitae (14–15, 14.8 avg.), P. lanei (14–16, 15.6 avg.), P. rupinus (13–15, 14 avg.), P. kropotkini (12– 14, 13.4 avg.), P. t. magnus (13–15, 14.3 avg.), P. muralis (12–13, 12.2 avg.) and P. tuberculosus (12–17, 14 avg.). Finally, P. benedettii presents the largest values in the following measures: 5.50 mm in length of the 4th toepad and 35.8 mm in axilla-groin length (LAG); compared to P. isabelae (4.1 mm, 22.2 mm), P. lupitae (4.9 mm, 31 mm), P. lanei (4.6 mm, 21.1 mm), P. rupinus (5 mm, 25.6 mm) and P. kropotkini (5 mm, 23 mm).
