Gekkonidae) has been discovered in East Java, Indonesia

Abstract

We describe a new species of Cyrtodactylus Gray from East Java (Maospati and Mojokerto), Indonesia that belongs to the C. sadlieri complex within the C. darmandvillei species group. It is a medium sized (SVL) species with adult males reaching 67.2 mm and females 59.0 mm, dorsal tubercles absent on brachium, present on antebrachium and along the ventrolateral fold; 18–20 irregular dorsal tubercle rows at midbody; 26–28 paravertebral tubercles per series; 28–34 ventral scale rows across belly; precloacal groove present with 32–37 precloacofemoral pores in males; enlarged femoral and precloacal scales arranged in a continuous series; abrupt transition between the enlarged femorals and the adjacent scales on the posterior margin of the thigh; subequal median subcaudal scales not transversely enlarged. The new species is genetically divergent from the other Javan congeners of the C. darmandvillei groupwith genetic divergences (p-distances) ranging from 7.7–12.1% for the mitochondrial ND2 gene.

English Common Name: Pecelmadiun’s Bent-toed Gecko

Indonesia Common Name: Cecak Jari Bengkok Pecel Madiun

Diagnosis. The following combination of characters distinguishes C. pecelmadiun sp. nov. from all other congeners: adult males reaching 67.2 mm SVL and females 59.0 mm SVL; dorsal tubercles absent on brachium, present on antebrachium and within the ventrolateral fold; 18–20 irregular dorsal tubercle rows at midbody; 26–28 paravertebral  tubercles  per  series;  28–34  ventral  scale  rows  across  belly;  precloacal  groove  present  with  32–37 precloacofemoral pores in males, absent in females; enlarged femoral and precloacal scales arranged in a continuous series; abrupt transition between the enlarged femorals and the adjacent scales on the posterior margin of the thigh; and subequal median subcaudal scales not transversely enlarged.

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.
