An interactive multi-entry key to the species of Megalostomis Chevrolat, with description of a new species from Paraguay (Chrysomelidae, Cryptocephalinae)
2014
Agrain, Federico Alejandro
The main goal of this contribution is to release an interactive multi-entry key to all known species of the genus Megalostomis Chevrolat. This key constitutes a new tool created to aid the identification of the spe- cies of this diverse genus, which occasionally may be difficult to identify to the species-level, due to the lack of reference collections for most countries within its distribution range, and to the presence of intra- specific variation and secondary sexual characters. It is expected that this on-line key will facilitate future periodic updates, and will benefit all those persons interested in identifying these taxa. The present paper also includes the description of Megalostomis juanenrique sp. n., a new species from Paraguay. In addition, Megalostomis gigas Lacordaire, and Megalostomis robustipes Monrós are newly cited for the fauna of Para- guay. The online interactive Lucid key is available at http://keys.lucidcentral.org/keys/v3/megalostomis. Offline Lucid data files in LIF and SDD formats are also available at doi: 10.3897/zookeys.425.7631. app1 and doi: 10.3897/zookeys.425.7631.app2.
