Abstract

PARADELL, Susana  and  DEFEA, Bárbara. Biodiversity indicators in scientific collections: diagnosis of the Cicadellidae collection (Insecta: Hemiptera) of Museo de La Plata, Argentina. Caldasia [online]. 2017, vol.39, n.1, pp.19-32. ISSN 0366-5232.  http://dx.doi.org/10.15446/caldasia.v39n1.54618.

The diversity of Cicadellidae (Hemiptera) housed in the collection of Museo de La Plata was characterized using the following indicators: 1) Taxonomic identification, degree of taxonomic resolution; 2) Taxonomic and geographic representativeness of the pinned specimens 3) Percentage of specimens associated with plants or parasitoids. These indicators were compared with available data for the Neotropical region and with The Collections Health Index (scales 6, 7 and 8). Seventy-four genera, 119 species and 2796 specimens of Cicadellinae, Coelidiinae, Deltocephalinae, Idiocerinae, Ledrinae and Xestocephalinae were recorded. To assess taxonomic identification, the specimens were grouped into four categories: A- Type material, labeled, databased, catalogued and published, B- Identified to species level, labeled and databased (scale 6 and 7 of the Collections Health Index), C-Identified to genus level, labeled and databased and, D- Identified to subfamily level, labeled and databased (8). From group A, 166 specimens were recorded, group B represented 94.95% of the total specimens studied (2655) (scales 6, 7), group C represented 2.18% (61 specimens) and D, 2.86% (80 specimens) (8). Taxonomic representativeness to subfamily level was 40.9% with respect to the Neotropics. At generic level, the subfamilies best represented were Xestocephalinae, Ledrinae (33.3%), Cicadellinae (18.7%) and Deltocephalinae (17.7%) and, to specific level, Ledrinae (12%), Deltocephalinae (6.5%) and Cicadellinae (4.2%). Cicadellinae and Deltocephalinae represent 96% of the total recorded specimens. The geographic representativeness was high 86.95% with respect to Argentina; only 12.53% of the specimens presented host plant data.
