Additional morphometrical and ecological data collected during the 2018 expedition of the UMMZ in Nicaragua

<p>Nicaragua is a biodiverse country, but documented herpetological specimens are underrepresented when compared to other neighboring countries. In 2018 we conducted a collaborative expedition between the University of Michigan Museum of Zoology and Nicaraguan biologists. We visited three collection sites in the Pacific lowlands, Caribbean lowlands, and the Central Highlands, representing three major biogeographic regions. We collected specimens of 100 species from a total of 106 encountered. We provide accession numbers, morphological, genetic, and ecological information for these specimens. We recorded 23 new departmental and the first country record of <em>Metlapilcoatlus indomitus</em> (Smith &amp; Ferrari-Castro, 2008), helping filling gaps in the known distribution of the species within Nicaragua and the Central American region. When available, we provide species range maps and comparative genetic tree including conspecific reference sequences from the region.</p>
