Ventral scales larger than dorsal scales, smooth, flat, imbricate, 30 ventral scale rows between ventrolateral body folds across the belly; enlarged scales immediately anterior to the cloacal opening absent. Forelimbs relatively short (ForL/SVL 0.15); dorsal scales on forelimbs and upper arms tri-keeled, forelimbs bearing tubercles, antebrachium lacking tubercles; palmar scales flat, smooth, subimbricate; digits well develop, inflected at basal interphalangeal joints, digits slightly narrower distal to inflection; subdigital lamellae transversely expanded along the entire length of each digit, but slightly compressed in both length and width immediately distal to interphalangeal inflection; subdigital lamellae on digits of manus: I(16), II(17), III(16), IV(15), V(14); claws well developed, sheathed by 2 dorsal scales and 1 ventral scale. Hindlimbs longer than forelimbs (TibL/SVL 0.18); covered dorsally by granular scales interspersed with larger, keeled tubercles; anterioroventral scales of thigh rounded, smooth, flat, subimbricate to juxtaposed; enlarged femoral and precloacal scales arranged in a continuous series, the largest in femoral part; precloacal groove present; 32 precloacofemoral pores in Ʌ-shape ( Figure 6); ventral scales on tibia smooth, flat, subimbricate; plantar scales slightly raised; digits well developed, inflected at basal metapodial-phalangeal joints, digits slightly narrower distal to inflection; subdigital lamellae transversely expanded along the entire length of each digit, but slightly compressed in both length and width immediately distal to interphalangeal inflection; subdigital lamellae on digits of pes: I(12), II(16), III(16), IV(18), V(17); claws well developed, sheathed by 2 dorsal scales and 1 ventral scale.   FIGURE 5.Living specimens of the Javanese  Cyrtodactylus, (A) adult male of  Cyrtodactylus pecelmadiun  sp. nov.from Maospati district, Magetan regency, East Java (holotype, MZB.Lace.15689), (B) adult male from Mojokerto, East Java (paratype, MZB.Lace.15690). Photos by A. Riyanto.   FIGURE 6.Precloacal depression and enlarged precloacofemoral scales of  Cyrtodactylus pecelmadiun  sp. nov.Illustration by A. Riyanto. Scale = 5 mm. Tail regenerated, 85.9 mmlength; on the original part segmented, dorsally with keeled tubercles arranged in transverse rows forming whorls and original part of subcaudal without enlarged transverse plates; three postcloacal tubercles (spur) on each side in both sexes.  Coloration in life.Ground coloration overlain with brown markings widely edged in black. On the flanks, tubercles edging the brown; dorsal markings are frequently bright-yellow, sharply contrasting with the adjacent color. The anterior supraciliaries are also yellow with some black areas. The rostral, mental, narial region, and labials are mostly charcoal to black, with yellow spots on the rostral and narial regions, and the labials are marked by widely spaced distinctive yellow spots. Dorsally, paired subcircular blotches cover the nape and extend to the original tail where they transform into irregularly shaped bands; seven paravertebral blotches between axilla to groin and five on original tail; on the flanks thin blotches bordered by a thin yellow line occur between paired blotches. The iris is greenish yellow, edged in yellow and bearing a black reticulum.  Variation.Males have precloacofemoral pores and a precloacal groove, whereas females do not. The last one-half to the tail in the holotypeis regenerated but complete in paratype(MZBLace 15690) ( Fig. 5B). Detailed variation of mensural and meristic characters of the type series are presented in Table 4.   Etymology.The specific epithet is a noun in apposition “pecel” and ‘madiun”. Pecel is a traditional chili sauce that is originally from East Java, and made from chili pepper, peanuts, garlic, lime, and palm sugar with various boiled vegetables (such as spinach, water spinach, casava leaves, papaya leaves, long beans, bean sprouts, or sesban flowers) and peanut brittle or anchovies as the secondary ingredients, and served in a plate made from banana leaves. Madiun refers to the name of the city that is famous for this traditional pecel culinary delight.  Comparison.  Cyrtodactylus pecelmadiun  sp. nov.differs statistically (p<0.05) from is sister species  C. petaniin the morphometric characters of SVL, AGL, HL, HW, HH, SL and OD, and the meristic characters DorT and VS. From more distantly related species in Javait differs from  C. marmoratus, it can be differentiated by smaller adult body size in SVL ( 67.2 mm versus 85.7 mm), fewer ventral scales (30–35 versus 34–46), precloacal groove in Ʌshape ( versusa deep inverse Y-shape), and fewer precloacofemoral pores (32–35 versus24–52) and fewer subdigital lamellae under the fourth toe (17–18 versus20–24 lamellae). It differs from  C. semiadiiin having a larger adult body size (known maximum SVL 67.2 mm versus 51.4 mm), precloacofemoral pores ( versusprecloacal pores), and abrupt transition ( versuslacking). It differs from  C. belanegarain having a larger adult body size (known maximum SVL 67.2 mm versus 53.8 mm), fewer ventral scales (28–34 versus37–40, and precloacofemoral pores ( versusdiscontinued precloacal and femoral pores).   TABLE 4.Meristic and morphometric data of the type series of  C. pecelmadiun  sp. nov., measurements in mm.     Characters   C. pecelmadiun  sp. nov.   MZB Lace 15689 15690 15691 15692 15693 15694 15695 15696 15697   Status holotype paratype paratype paratype paratype paratype paratype paratype paratype   Sex male male female, subadult female male male male male male   Tubercles on occiput present present present present present present present present present   Tubercles on upper arms absent absent absent absent absent absent absent absent absent   Enlarged transverse median subcaudal absent absent absent absent absent absent absent absent absent   Precloacal depression groove no no groove groove groove groove groove groove   SVL 64.5 61.1 55.5 59.0 67.2 63.2 62.7 65.4 63.7   TL/SVL reg 1.40 reg broken reg reg reg reg 1.26   AGL/SVL 0,42 0.46 0.42 0.44 0.43 0.45 0,43 0.43 0,44   HL/SVL 0.28 0,31 0.29 0,29 0.28 0.28 0.28 0.29 0.29   HW/SVL 0.21 0.21 0.19 0.19 0.19 0.20 0.21 0.20 0.21   HW/HH 1.72 1.64 1.63 1.62 1.79 1.87 1.29 1.76 1.90   SL/HL 0.44 0.40 0.40 0.38 0.39 0.42 0.38 0.39 0.41   EE/OD 1.26 1.24 1.24 1.23 1.53 1.04 1.40 1.23 1.49   DorT 20 20 18 20 18 20 20 18 18   PVT 26 27 26 28 28 27 28 28 26   VS 30 34 34 34 28 30 32 32 32   PFP 32 37 32 35 32 37 35 35 37   T 4 19 18 19 19 18 18 16 17 18 It differs from  Cyrtodactylus batucolusGrismer, Onn, Grismer, Wood & Belabut, 2008from Malaysiaby having fewer precloacofemoral pores (32–37 versus43–46) and a smaller maximum adult SVL ( 67.2 mm versus 75.2 mm). From  C. seribuatensis Youmans & Grismer, 2006from Malaysiait differs in having fewer precloacofemoral pores (32–37 versus40–44) and a smaller maximum adult SVL ( 67.2 mm versus 75 mm). Detailed comparison among other species of the  C. sadleiricomplex are presented in Table 5.   Distribution and natural history.  Cyrtodactylus pecelmadiun  sp. nov.was collected in the lowlands of East Java. The typeseries was collected from a variety of habitats, i.e. paddy field embankments, a pile of building tiles left over from the building near the bushes and gardens in the village ( Figure 1B & C). All were found no more than 40 cmabove the ground. Given these observations, we consider this species as a habitat generalist ( sensuGrismer et al. 2021). 5052384303 2023-05-09 MZB Awal Riyanto & Asrael Racho Indonesia Magetan Regency 137 -7.59701 Tanjungsepreh Village 5 111.4141 Maospati District 6 87 MZB Lace 15689 2 1 1 East Java Province holotype 5052384302 2023-03-11 MZB Awal Riyanto & Richo Firmansyah & Nanang Kamaludin & Faturrahman Indonesia Mojokerto Regency 60 -7.51245 Pekukuhan Village 55 112.527 Mojosari 6 87 MZB Lace 15690, MZB Lace 15691 4 2 1 1 East Java Province paratype 5052384301 2023-03-12 MZB Awal Riyanto & Richo Firmansyah & Nanang Kamaludin & Faturrahman Sidiq Indonesia Magetan Regency 137 -7.59619 Tanjungsepreh Village 1 111.41171 Maospati District 6 87 MZB Lace 15692 1 1 East Java Province 5052384304 [375,1295,719,746] 2023-05-09 MZB Awal Riyanto & Asrael Racho Indonesia Magetan Regency 137 -7.59701 Tanjungsepreh Village 5 111.4141 Maospati District 6 87 MZB Lace 15693, 15694, 15695, 15696, 15697 1 1 East Java Province
