Identification keys are presented in two different formats: traditional dichotomous keys where a choice needs to be made at each key couplet to continue, and Lucid matrix keys where relevant states from multiple character features can be selected independently until identification is achieved. For more information concerning Lucid keys visit www.lucidcentral.org.

About the Lucid matrix identification key

The Lucid matrix key has been designed for the specific identification of Ophioninae reported in the Afrotropical Region, mostly based on the morphological revisions of Gauld & Mitchell, 1978, Gauld & Mitchell, 1981 and Gauld (1982).  We recommend close consultation with these revisions while using the above Lucid matrix key.

1. Intensive use of the magic wand button is recommended to find the best discriminative feature.

2. Quantitative indices are given with second and third quartiles in square brackets, i.e. the range encompassing 50% of the reported values. The more out of this range a measure is, the more diagnostic the character is.

3. The limits of the states of quantitative indices were determined according to the statistical distribution of the variable, and the species have been coded loosely to avoid false negative. If you measure a value close to one of the limits, we recommend that you select the corresponding alternative option as well.
