Abbreviations: Ca = calyces, CF = crotch flap, SS = sulcus spermaticus. Photographs by MYM. Scale bars = 5 mm. Adult female JMG 0485 ( Fig. 4 C, D, center): dorsum of head, body, limbs and tail brown; dorsum of body with three broad, dark brown transverse bands extending onto flanks; vertebral region of dorsum with dark brown spots; dorsum of limbs and tail with dark brown transverse bands; flanks of neck and body with dark brown spots; ventral aspect of head, body, limbs, and tail dirty cream; dewlap skin creamish white with black blotches; scales of dewlap creamish white. Adult female QCAZ 14432 ( Fig. 4 C, D, right side) differs from JMG 0485 in having faint dorsal transverse bands and small dark brown spots on limbs ventrally. Female hatchling QCAZ 14660 ( Fig. 4 C, D, left side) differs in having four dark brown transverse bands (discontinuous medially) on ventral aspect of head and dark brown transverse bands ventrally on limbs.  Hemipenis.Partially everted hemipenis small ( 7.3 mmtotal length, 2.9 mmtruncus length) and slightly bilobate; sulcus spermaticus unforked, bordered by well-developed lips and opening into a single, smooth apical area; lobes with small calyces on asulcate side; fleshy projection on lobular crotch (crotch flap) on asulcate surface; truncus with transverse and lateral folds ( Fig. 6).   Distribution and natural history.  Anolis nemonteaeoccurs on the Pacific slopes of the Andes in southern Ecuador, El Oro province, between 372−1,000 m( Fig. 7). This species occurs in the Evergreen Foothills Montane Forest of Catamayo-Alamor (Ministerio del Ambiente del Ecuador2013). Specimens of  Anolis nemonteaewere collected mainly in secondary forest and along the edge of roads ( Fig. 8). All individuals were found at night between 20:00 and 01:00 h sleeping horizontally on branches of trees, or leaves of bananas or Panamahat plants, 2.5–6.9 mabove ground. A male and a female (JMG 0484, 0485) were found sleeping on banana leaves 10 maway from each other, 2.5 mabove the ground.  Anolis nemonteaeoccurs in sympatry with  A. binotatus Peters 1863and  A. fasciatusat the typelocality ( Yánez-Muñoz et al.2013, Garzón et al.2019).   FIGURE 8.Entrance to Buenaventura Reserve, type locality of  Anolis nemonteae  sp. nov., showing its general habitat. Photograph by AEN.  A captive female ( QCAZ 14594[tissue sample], SVL= 93.21 mm) that was subsequently released laid one egg(22.3 x 14.4 mm) on  30 January 2016. The egg was incubated in perlite at 19°C and 85% of relative humidity. After an incubation period of 129 days, a female ( Fig. 3F; QCAZ 14660, SVL= 32.9 mm, weight = 2.3 g) hatched.  Conservation.The known distribution area of  Anolis nemonteaehas suffered from dramatic deforestation ( Tapia-Armijos et al.2015). However, most individuals of  A. nemonteaewere collected within the Buenaventura Reserve, which suggests that at least some of its populations are well protected. Because of the small known distribution ( Fig. 7) and lack of additional data, we suggest assigning  A. nemonteaeto the Data Deficient category according to IUCN (2012)guidelines.   Etymology.The specific epithet  nemonteaeis a noun in the genitive case and is a patronym for Nemonte Nenquimo, indigenous activist who led a successful campaign and legal action that protected 500,000 acres of Amazonian rainforest and Waorani territory from oil extraction in Ecuador. Nemonte means ‘many stars’ in Wao Tereo language. Nemonte Nenquimo’s work has been recognized worldwide. In 2020, she was awarded the prestigious Goldman Prize and was listed among the 100 most influential people of the year by the Time Magazine. Here we honor Nemonte Nenquimo for her braveness and determination to protect natural forests and their inhabitants.   FIGURE 9.Phylogeny of the clade  Dactyloa, with a close-up of the  latifronsseries as defined by Castañeda & de Queiroz (2013)and Prates et al.(2020). Maximum clade credibility tree obtained from a Bayesian analysis of 125 taxa and 3,221 characters. Numbers above branches are Bayesian posterior probability (PP) values and those below branches are ML bootstrap support (BS) values. GenBank accession numbers along with locality data are presented in Table 1 for newly sequenced specimens.   FIGURE 10.Reflectance of the gular sac in males and females of  Anolis nemonteae  sp. nov.and  A. fraseri. Measured regions are gular sac base ‘DB’, center ‘DM’, and edge ‘DE’, as well as regions close to the head ‘DH’ and the abdomen ‘DA’. Photo- graphs by AEN (male and female of  A. nemonteae sp. nov.), D. Quirola (female of  A. fraseri) and FAV (male of  A. fraseri).  Phylogenetic relationships.Data partitions and models of evolution are presented in Table 4. Both ML and Bayesian analyses positioned  Anolis nemonteae sp. nov.within a clade highly congruent with the  Megaloaclade of Castañeda & de Queiroz (2013)with maximum support ( Fig. 9). The difference to the  Megaloaclade as originally defined is that  Anolis ibanezi,  A. kunayalae, and  A. pariliswere also included ( Fig. 9). As expected,  A. ginaelisaeand  A. maia, both described more recently, were also included in this clade ( Lotzkat et al.2013, Batista et al.2015). Both ML and Bayesian tree topologies for the  Megaloaclade are identical, except for the sister species of  A. maculigula(  A. casildaeand  A. apollinaris, respectively). The sister species of  A. nemonteae sp. nov.is  A. fraseri(PP = 0.98, BS = 65), and together they form a clade sister to  A. parilis(PP = 1, BS = 84). Interspecific genetic distances among sampled species of the  Megaloaclade range from 0.02 (  A. fraseri/  A. parilis,  A. latifrons/  A. princeps) to 0.23 (  A. latifrons/  A. microtus,  A. microtus/  A. princeps) for ND2and from 0.02 (  A. latifrons/  A. princeps) to 0.19 (  A. kathydayae/  A. fraseri,  A. maculigula/  A. nemonteae,  A. parilis/  A. maculigula) for COI. Genetic distances between  Anolis nemonteaeand  A. fraseriare 0.03–0.05 ( ND2) and 0.05–0.06 ( COI).  Dewlap reflectance.The dewlap of  Anolis nemonteaereflects light in the visible spectrum in both sexes ( Fig. 10). Reflectance starts increasing significantly at around 400 nmin males and 500 nmin females, and it reaches a peak (~50%) at ~ 530 nm. Light is also reflected near the ultraviolet spectrum (~15% at 320 nm) in females.   Remarks.  Anolis nemonteaeis most similar in morphology to its sister species  A. fraseri. Even their hemipenes only seem to differ in relative size (smaller in  A. nemonteae) and in having more pronounced calyces on the asulcate side in  A. fraseri( Fig. 6), although the variation of these characters should be analyzed with a larger sample size. However, in addition to the differences presented above, the dewlap of males of the new species is different from both sexes of  A. fraseriin lacking reflectance within the ultraviolet spectrum ( Fig. 10). The dewlap of both sexes of  A. fraserireflects light with a peak near the ultraviolet spectrum (~10% at 350 nm). Although it has been reported in only a few species of anoles (e.g., Fleishman et al. 2009; Torres-Carvajal et al. 2018), data on reflectance spectroscopy of dewlaps seems to be informative for species delimitation and should be explored in more detail. 3320589310 2016-01-30 WGS Andrea Narvaez & Sebastian Valverde & Keyko Cruz & David Reyes.
