All paratypes were collected by Juliana Zina, between July 2007 and January 2008.
Diagnosis and comparison with other species. The new species is assigned to the genus Scinax based on the identification of the morphological synapomorphies suggested by Faivovich (2002): webbing between Toes I and II that does not extend beyond the subarticular tubercle of Toe I, origin of the m. pectoralis abdominalis at well defined tendons, ability to bend backwards Finger II and Toe I, and m. pectoralis abdominalis overlapping m. obliqus externus. Moreover, S. caissara is assigned to the S. catharinae species group due to the laterodistal origin of the m. extensores brevis distalis digit III, phenotypic synapomorphy pointed out by Faivovich (2002).
This new species is characterized by small size (SVL of males 18.8–23.2, n = 26; SVL of females 20.1–27.5, n = 5); subovoid snout in dorsal view; canthus rostralis marked; loreal region concave and oblique; vocal slits present in males; males with vocal sac not expanded; presence of glandular acini on the mental region ( Fig. 3View FIGURE 3); absence of macroscopic glandular acini on the pectoral region; pectoral fold absent; absence of macroscopic glandular acini on the medial region of the forearm; presence of macroscopic glandular acini on the dorsal region of the Fingers II and III; nuptial pad with the glandular acini diffuse over the skin and not cohesive, not forming an elevated structure on the skin; interocular region with a w-shape blotch that exceeds the posterior margin of the eyes; skin on dorsum smooth; belly and gular region cream with irregular lines and scattered dots; absence of bright coloration on inguinal region and hidden portions of the thigh and shank; presence of inguinal gland ( Fig. 4View FIGURE 4); the foot webbing reaches the second subarticular tubercles or at most a half of the penultimate phalanx of Toe V.
Scinax caissara is distinguishable from all species of Scinax for having glandular acini on mental region. Further, the presence of an inguinal gland distinguishes the new species from S. centralis ( Pombal & Bastos, 1996) —that has a particularly hypertrophied one—and from S. agilis (Cruz & Peixoto, 1983 "1982"), S. albicans ( Bokermann, 1967) , S. angrensis ( Lutz, 1973) , S. argyreornatus ( Miranda-Ribeiro, 1926) , S. aromothyella , S. berthae , S. carnevallii (Caramaschi & Kisteumacher, 1982) , S. heyeri ( Weygoldt, 1986) , S. humilis ( Lutz, 1954) , S.
kautskyi (Carvalho-e-Silva & Peixoto, 1991), S. littoralis ( Pombal & Gordo, 1991) , S. machadoi ( Bokermann & Sazima, 1973) , S. muriciensis Cruz, Nunes & Lima, 2011 , S. pombali Lourenço, Carvalho, Baêta, Pezzuti & Leite, 2013 , S. skuki Lima, Cruz & Azevedo, 2011 , S. strigilatus ( Spix, 1824) , and S. trapicheiroi ( Lutz, 1954) that do not have inguinal gland.
Scinax caissara differs from S. angrensis , S. ariadne ( Bokermann, 1967) , S. brieni ( De Witte, 1930) , S. catharinae ( Boulenger, 1888) , S. humilis , S. jureia ( Pombal & Gordo, 1991) , S. kautskyi , S. littoralis , S. muriciensis , S. obtriangulatus ( Lutz, 1973) , S. skaios Pombal, Carvalho, Canelas & Bastos, 2010 , S. strigilatus , and S. trapicheiroi by the smaller size of males and females (SVL of males in S. caissara 18.8–23.2; combined SVL of males in these species 23.6–42.8; SVL of female in S. caissara 20.9–27.5; combined SVL of females in these species 28.7–47.0); from S. agilis , S. argyreornatus , S. melanodactylus Lourenço, Luna & Pombal, 2014 , and S. skuki by the larger size of males (combined SVL of males in these species 12.0–18.4) and from S. agilis and S. melanodactylus by the larger size of females (combined SVL of females in these species 13.2–18.9); from S. albicans , S. canastrensis ( Cardoso & Haddad, 1982) , S. carnevallii , S. flavoguttatus ( Lutz & Lutz, 1939) , S. hiemalis ( Haddad & Pombal, 1987) , S. pombali , and S. tripui Lourenço, Nascimento & Pires, 2009 by smaller size of females (combined SVL of females in these species 28.3–47.0).
The new species differs from S. agilis , S. albicans , S. angrensis , S. aromothyella , S. carnevallii , S. catharinae , S. brieni , S. flavoguttatus , S. humilis , S. littoralis , S. luizotavioi ( Caramaschi & Kisteumacher, 1989) , S. obtriangulatus , S. rizibilis ( Bokermann, 1964) , S. trapicheiroi , and S. tripui in having nuptial pad where the glandular acini are diffuse over the skin and not cohesive, not forming an elevated structure on the skin (in these species the nuptial pad is an elevated structure with respect to the surrounding skin, and particularly enlarged in S. rizibilis ).
The new species differ from most species of the S. catharinae group except S. agilis , S. canastrensis , S. centralis , S. longilineus ( Lutz, 1968) , S. machadoi , S. melanodactylus , S. pombali , S. rizibilis , and S. skaios by its subovoid snout in dorsal view (subelliptical in S. aromothyella and S. berthae ; rounded in S. ariadne , S. catharinae , S. brieni , S. obtriangulatus , and S. ranki ; rounded with a mucronate tip in S. albicans , S. angrensis , S. flavoguttatus , S. hiemalis , S. heyeri , S. humilis , S. littoralis , S. muriciensis , S. strigilatus , S. trapicheiroi , and S. tripui ; mucronate in S. carnevallii and S. kautskyi ; sub-elliptical with acute tip in S. jureia and S. luizotavioi ; mucronate or subelliptical in S. argyreornatus and S. skuki ).
Scinax caissara differs from S. agilis , S. albicans , S. argyreornatus , S. aromothyella , S. berthae , S. machadoi , S. melanodactylus , S. ranki , and S. rizibilis in having well marked canthus rostralis (canthus rostralis not well marked in these species).
The presence of vocal slits differentiates the new species from S. ariadne and S. skaios (vocal slits absent). The new species is distinguished from S. aromothyella , S. berthae , and S. rizibilis by its vocal sac not expanded externally (notably expanded in these species).
The new species differs from S. canastrensis , S. carnevallii , S. flavoguttatus , S. kautskyi , S. longilineus , S. machadoi , S. muriciensis , S. skaios , S. strigilatus , and S. tripui by the absence of glandular acini on the medial region of forearm (glandular acini present on the medial region of forearm in these species).
The presence of glandular acini on the dorsal region of the Finger III in males distinguishes the new species from S. agilis , S. argyreornatus , S. ariadne , S. aromothyella , S. berthae , S. centralis , S. heyeri , S. hiemalis , S. jureia , S. melanodactylus , S. muriciensis , S. pombali , S. ranki , S. rizibilis , S. skaios , S. skuki , and S. strigilatus (glandular acini absent on Finger III in these species).
Scinax caissara differs from most species of the S. catharinae group except S. aromothyella and S. berthae , in having smooth skin on dorsum (rough in S. ariadne , S. canastrensis , S. longilineus , S. pombali , and S. skaios ; covered by scattered tubercles in the remaining species).
Some species of the S. catharinae group have more developed foot webbing, reaching the base of the adhesive disc on the medial margin of the Toe V. This is the case of S. argyreornatus , S. aromothyella , S. catharinae , S. kautskyi , S. flavoguttatus , S. heyeri , S. luizotavioi , S. muriciensis , S. skuki , S. strigilatus , and S. tripui . Scinax caissara differs from these species because its interdigital webbing is less developed, reaching only the second subarticular tubercles or at most a half of the penultimate phalanx of Toe V.
Scinax caissara differs from most species of the S. catharinae group except S. albicans , S. argyreornatus , S. carnevallii , and S. kautskyi in having a interocular W-shaped blotch that does not exceeds the posterior margin of eyes ( S. flavoguttatus , S. heyeri , S. machadoi , S. muriciensis , S. rizibilis , S. strigilatus , and S. tripui , have a Wshaped blotch on the interocular region that exceeds the posterior margin of the eyes; S. agilis and S. melanodactylus have a black longitudinal line on the interocular region or they have no mark on this region; S. aromothyella and S. berthae have an inverted triangle or an irregular band on this region that does not exceeds the posterior margin of eyes; S. ariadne , S. brieni and S. catharinae have an inverted triangle or an irregular trapezoid mark on this region that exceeds the posterior border of the tympanum; S. canastrensis , S. centralis , S. hiemalis , S. jureia , S. longilineus , S. luizotavioi , S. ranki , and S. skaios have a inverted triangle on this region that exceeds the posterior border of eyes; S. angrensis , S. humilis , and S. littoralis have a complete or interrupted band on this region, which is narrow and restricted to the median interocular region; S. pombali and S. obtriangulatus have an inverted triangle on this region that exceeds the posterior border of the tympanum; S. trapicheiroi has a W-shaped blotch, which is very long, extending far beyond the interocular region, reaching half of the body).
The cream belly with scattered and irregular lines and dots differentiates the new species from S. agilis , S. albicans , S. angrensis , S. ariadne , S. argyreornatus , S. aromothyella , S. berthae , S. canastrensis , S. carnevallii , S. centralis , S. flavoguttatus , S. heyeri , S. hiemalis , S. humilis , S. kautskyi , S. littoralis , S. longilineus , S. luizotavioi , S. machadoi , S. melanodactylus , S. muriciensis , S. obtriangulatus , S. pombali , S. ranki , S. rizibilis , S. skaios , S. skuki , S. strigilatus , S. trapicheiroi , and S. tripui ( S. ariadne , S. flavoguttatus , and S. tripui have irregular cream spots on brown background in this region; the remaining species have fully uniform cream belly).
The new species has no flash color on the inguinal region and hidden areas of the thigh and shank, unlike S. ariadne (light brown irregular blotches on violet or pink background; personal observation), S. aromothyella (dark yellow; Faivovich 2005), S. berthae (“irregular yellow-orange spots”; Barrio 1962), S. brieni (“pale bluish color on the concealed areas”; Lutz 1973), S. canastrensis (“yellow”; Cardoso & Haddad 1982), S. catharinae , S. humilis , and S. trapicheiroi (dark brown blotches on light blue or white background; personal observation), S. centralis (“yellow on dark brown background”; Pombal & Bastos 1996), S. flavoguttatus and S. heyeri (brown blotches on orange background; personal observation), S. hiemalis (“black blotches on green background”; Haddad & Pombal 1987), S. longilineus and S. machadoi (vermiculate spots on yellow or pale background; personal observation), S. obtriangulatus (“dull grayish violet”; Lutz 1973), S. pombali (irregular brown blotches on yellow background; personal observation), S. ranki (dark brown blotches on greenish background; personal observation), S. skaios (vermiculated dark brown spots on light green background; personal observation), S. strigilatus (“concealed surfaces of flanks and thighs greenish”; Pimenta et al. 2007), and S. tripui (irregular brown blotches on light green background; personal observation).

The type series of Scinax caissara was collected in coastal municipalities of the southern State of São Paulo ( Fig. 5View FIGURE 5). These areas belong to four contiguous municipalities: Cananéia, Ilha Comprida, Pariquera-Açu, and Iguape. The sampled localities are very close to each other, not exceeding 30 km between the more distant areas.
Specimens were collected in temporary water bodies located in the forested areas of coastal sandbanks. Males call from leaves and branches of the marginal vegetation, are about one meter above the water. They call mainly during the wet season (from September to March) or after rainy days during the dry season (from April to August), when temporary water bodies inside forested fragments are formed. One female has approximately 280 oocytes ( CFBHAbout CFBH 19409).
Advertisement call. The call of S. caissara is composed by a single multipulsed note (N = 166 calls; nine males) with tightly packed pulses ( Fig. 6View FIGURE 6). These are increasingly juxtaposed with descending amplitude modulation. This conformation hampers the count of the last pulses that are hardly individually delimited. The note, as a whole, has shorter attack than the decay, that is, amplitude peaks near to the beginning of the note. Note duration (=call duration) ranges from 0.01 to 0.024 s (x = 0.02 ± 0.018; N = 166 notes), emitted with extremely variable intervals, ranging from 0.01 to 32.7 s (x = 6.4 ± 6.7; N= 147 intervals). Dominant frequency varied from 3.1 to 4.4 kHz. However some dominant frequencies are more common, such as 3.2 kHz (N = 29 calls; five males), 3.4 kHz (N = 24 calls; five males), 3.6 kHz (N = 23 calls; six males), 4.1 kHz (N = 21 calls; six males), and 4.3 kHz (N = 20 calls; six males). The less common dominant frequency was 4.4 kHz (N = 7 calls; three males). The multipulsed structure results in two clearly visible sidebands in all calls, one ranging from 3.1 to 3.5 kHz and another ranging 4.2 to 5.0 kHz (N= 166 calls). These frequencies are not multiple to each other, so they do not represent harmonics.
The vocalizations of the S. catharinae group are complex ( Pombal et al. 1995; Pombal & Bastos 1996) and calls of 18 species have already been described ( Table 2). The comparison among these calls is quite complicated and need a previous standardization to be properly executed. Nevertheless, some differences can be noted and thus used to distinguish the new species. Among all species of the S. catharinae group, S. agilis has the most distinctive call; promptly differentiated from S. caissara by its much longer note and lower pulse rate. The calls of S. caissara , S. centralis , and S. luizotavioi are unique among species with known call in the S. catharinae group for having a single note, whereas all others have more than one note. However, S. caissara has shorter call duration (0.01 to 0.024 s) when compared with the calls of these two species (0.37 s in S. centralis and 0.05 to 0.54 s in S. luizotavioi ; Pombal et al. 1995; Lourenço et al. 2009b). For comparisons and more details about calls of the S. catharinae group see Table 2.
Kayotype. Both studied specimens presented karyotypes with 2n = 24 biarmed chromosomes (FN = 48). Chromosomes gradually decrease in size with the first six pairs being large or medium, and the last six small-sized ( Table 3). Morphologically, pairs 1–5 and 7 were submetacentrics, pair 6 was subtelocentric, and pairs 8–12 were all metacentric ( Fig. 7View FIGURE 7). Meiotic analyses from testicular cells exhibited 12 bivalents in metaphase I cells and, as expected, metaphase II cells presented 12 chromosomes.

In CFBHAbout CFBH 19545 the Ag-NOR labeling were detected interstitially on pair 6 p, but an additional pericentromeric labeling occurred at one of the homologues of pair 2 q ( Fig. 7View FIGURE 7 inset c). In CFBHAbout CFBH 19546 the labeling pattern appears only in one homologue of each chromosome pair 2 q and 6 p ( Fig. 7View FIGURE 7 inset a).
Etymology. Caiçara is a Tupi-Guarani word meaning “fence of branches”. This word is a Brazilian popular designation for the native people living in southeastern and southern coasts of Brazil. This name is quite appropriate considering the distribution of the new species, occurring in places were the caiçara people live. Spelling was altered to conform the original sonority to the Roman Alphabet.
