|Diagnosis||Diagnosis. Phyllodactylus kropotkini sp. nov. is a medium-sized gecko within the P. lanei complex. 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 kropotkini has 14.6 interorbital scales on average (14–15), white venter and 20.2 third labial–snout scales on average (19–21). Phyllodactylus kropotkini presents a maximum recorded SVL of 62.3 mm that clearly differs from the nearest species P. lanei (max. 71 mm) and it differs from other species: P. isabelae (max. 57.5), P. lupitae (max. 73.3 mm), P. rupinus (max. 69.4), P. benedettii (max. 74.2) and P. bordai (max. 58.9 mm). Phyllodactylus kropotkini sp. nov. shows the following combination of characters: 28 (25–31) tubercles from head to tail, 67 (63–73) longitudinal scales, 13 (12–14) rows of tubercles across dorsum, 30 (29–33) scales across venter, 14 (14–15) interorbital scales and 20 (19–21) third labial–snout scales. Phyllodactylus kropotkini has a partial overlap with P. lanei and P. isabelae on morphometric space (Fig. 7), however P. kropotkini is clearly differentiated from P. lanei by maximum length (SVL) (Fig. 6); it also presents the follow measures: axilla-groin length (22.54 mm), snout length (9.34 mm), auricular opening (1.78 mm), while P. lanei has 24.7 mm axilla-groin length, 10. 61 mm snout length and auricular opening (1.95 mm) and P. isabelae has 18.7 mm axilla-groin length, 8.18 mm snout length and auricular opening 1.51 mm.|
P. kropotkini has a low number of interorbital scales (14–15, 14.6 avg.) similar to P. benedettii (13–16, 14.4 avg.), all other species of Phyllodactylus exceed 15 interorbital scales on average, P. isabelae (14–16, 15.1 avg.), P. lupitae (14–20, 16.83 avg.), P. lanei (15–17, 15.5 avg.), P. rupinus (14–17, 15.5 avg.), P. t. magnus (21–23, 22.3 avg.), P. muralis (21–27, 23.2 avg.), P. tuberculosus (16–22, 19.2 avg.). There are an average of 30.6 scales across the venter (29–33), unlike P. isabelae (26–29, 27.8 avg.), P. lupitae (23–26, 24.6 avg.), P. lanei (29–32, 30 avg.), P. rupinus (24–28, 26.5 avg.) and P. benedettii (25–32, 29.1 avg.). Phyllodactylus kropotkini presents 67.6 longitudinal scales from the gular region to the anus on average (63–73), compared to P. rupinus (63–73, 63.6 avg.), P. lanei (60–74, 66 avg.), P. benedettii (60–69, 62.6 avg.), P. t. magnus (52–58, 54.6 avg.), P. muralis (57–61, 59 avg.) and P. tuberculosus (51–64, 57.7 avg.). This species also has 28.4 tubercles from head to tail on average (25–31), different from P. rupinus (26–30; 28 avg.), P. lanei (32–34, 33.2 avg.), P. benedettii, (24–30, 27.4 avg.), P. isabelae (30–35, 32.2 avg.), P. lupitae (27–31, 28.8 avg.), P. t. magnus (35–40, 38 avg.), P. muralis (30–40, 33.6 avg.) and P. tuberculosus (33–41, 36.4 avg.) tubercles. It also presents 13.4 rows of tubercles on average across the dorsum (12–14), different from P. rupinus (13–15, 14 avg.), P. benedettii (13–14, 14.4 avg.), P. lupitae (14–15, 14.8 avg.), P. lanei (14–16, 15.6 avg.), P. isabelae (15–18, 16.7 avg.), P. t. magnus (13–15, 14.33 avg.), P. muralis (12– 13, 12.2 avg.) and P. tuberculosus (12–17, 14 avg.). Finally P. kropotkini presents 20.2 third labial–snout scales (19–21), similar to P. rupinus (18–22, 20.6 avg.) and it differs from the other species of Phyllodactylus: P. isabelae (19–24, 21.4 avg.), P. lupitae (23–28, 25.5 avg.), P. lanei (20–23, 21.2 avg.), P. benedettii (22–23, 22.3 avg.), P. t. magnus (24–26, 24.6 avg.), P. muralis (24–28, 25.2 avg.) and P. tuberculosus (21–26, 24.2 avg.).
|Comment||Habitat: rocks and between cracks in caves. The specimens were collected in the house of a person who allowed collection inside his home.|
|Etymology||The species is dedicated to the memory of the great Russian philosopher, geographer and naturalist Piotr Kropotkin, who made great scientific and theoretical contributions about mutual support and altruism in some animal populations (including human society).|
