Abstract
Four new species of the sciophiline genus Eudicrana Loew are described for the Eastern and Central Andes of Colombia–Eudicrana silvaandinasp. nov., E. chingazasp. nov., E. maculatasp. nov. and E. merizaldei. These are the first species of Eudicrana described from the extreme northern range of the Andes. The altitudinal distribution of these species in the paramos and high Andean forest ecosystems is restricted to 1750–3660 m a.s.l. and some other information on the environment is briefly discussed. A key for the Colombian species of Eudicrana is provided and a discussion is elaborated on the position of these species within the genus.
Highlights
The genus Eudicrana was originally proposed by Loew (1869) based on a single female of the type species of the E. obumbrata, from North America
The genus is known from 11 other species: E. nigriceps Lundström from Europe (Lundström 1909) and E. affinis Okada from Japan (Okada 1938), E. monticola Tonnoir and E. nicholsoni Tonnoir from Australasian (Tonnoir 1929) and E. araucariae Matile, from New Caledonia (Matile 1991), and six Neotropical species–E. basinerva Freeman, E. pallida Freeman and E. similis Freeman, from the Argentinian Patagonia and southern Chile (Freeman 1951), E. claripennis Edwards and E. vittata Edwards, from Peru (Edwards 1931), and E. splendens Lane, from southeastern Brazil (Lane 1948)
This paper describes the first four known species of Eudicrana of the high Andean ecosystems of the Central and Eastern Cordilleras of Colombia
Summary
The genus Eudicrana was originally proposed by Loew (1869) based on a single female of the type species of the E. obumbrata, from North America. New combination– Neuratelia elegans (Lane, 1948)–was recently proposed for a Brazilian species Eudicrana elegans Lane by Henao-Sepúlveda et al (2019). In Borkent and Wheeler’s (2013) phylogenetic study of the Sciophilinae, Eudicrana appears as monophyletic in a clade including Polylepta Winnertz and its sister genus, Leptomorphus Curtis. Both these genera share the presence of setae at the anterior part of the mediotergite.
