Key SearchWelcome to the Lucidcentral Key Search

There are two ways you can search for a key in the Lucid key database. First, you can type in a word or words in the “Search” box to the right of the screen and press Go. This search will display all those keys that have the word(s) you entered in the title of the key. The alternative way is to use one or a number of the search categories below, using the drop down menus. So, for instance, you could search for an internet key (under Media/Deployment), of Higher plants (Taxonomic scope), terrestrial (Habitat) and Australia (Geo Scope).

We recommend that you check whether you have the latest (free) version of Java Runtime Environment and if necessary upgrade to the latest version when running keys based on the Lucid Player applet.

Key to the invasive terrestrial plants in Europe


This key helps to identify the major invasive terrestrial plants in NW Europe. Invasive are those species that pose a threat to the biodiversity of the ecoregion. Species included are both those that already are known to be invasive in this region, as well as species known to be invasive elsewhere in comparable climatic regions. Moreover, look-alikes are included to distinguish closely related taxa. A total of 140 species is included. All features are illustrated with botanical drawings so that no knowledge of botanical terms is needed, basic knowledge of plant morphology, however, is helpful. The keys link to complete species descriptions on the Q-bank – Plants website. All species are well illustrated by photographs showing distinguishing characteristics or invaded sites. The key is regularly updated with new species and new photographs. Species that are imported in Europe as weeds in potplants are treated in a separate key. This key is also available in French and Dutch.


Q-bank – Comprehensive databases on plant pests and diseases covers the following organism groups that contain quarantine organisms:

  • Fungi
  • Bacteria
  • Invasive Plants
  • Nematodes
  • Arthropods
  • Phytoplasma’s
  • Viruses and viroids

The databases are curated by internationally known specialists and contain specimen-based information including molecular data. The website offers the possibility to blast, in single- or multi-locus mode, sequences for identification.

Fiji Herpetofauna

Herpetofauna is the collective term for the members of two vertebrate classes, the amphibians and the reptiles. The known terrestrial herpetofauna of Fiji consists of 30 species: 3 frogs, 2 iguanas, 3 snakes, 10 geckos and 12 skinks. Forty percent (12/30) of these species are endemic to Fiji . With the exception of three regionally endemic species, the terrestrial herpetofauna of Fiji are generally widely distributed in terms of geography, habitat type or in some cases, both.

In addition to these terrestrial species, five species of marine turtle and four species of sea snake are found in Fiji. All these marine species are widespread throughout the Pacific and none are endemic to Fiji.

Fiji has long lacked comprehensive field guides for the enthusiastic naturalist or serious biologist; A Field Guide to the Herpetofauna of Fiji is a welcome addition to the ranks. Written by Clare Morrison, who grew up in Fiji, it includes full color photos of every known Fijian species.

SPIKEY: An interactive key to Triodia spinifex grasses of the Pilbara, Western Australia  --  VISIT
 Views: 38

Updated: Mon 06/05/2017 @ 04:19

SPIKEY: An interactive key to Triodia spinifex grasses of the Pilbara, Western Australia is an interactive identification tool covering all of the hummock grasses (the genus Triodia) colloquially known as ‘spinifex’ that occur in the Pilbara bioregion and adjacent areas of Western Australia. This key covers a total of 28 species and one hybrid, about one-quarter of the species in the genus Triodia, using 28 features. This is an important update; about half of the species treated are recently described, and are not covered by earlier synopses of Triodia. Triodia are the dominant plants and a major restoration target in arid zone hummock grasslands, an ecosystem covering 18% of Australia, and correct identification is critical to successful restoration and rehabilitation. This app is intended to be used by land managers, rehabilitation practitioners, botanical consultants, seed collectors, identification botanists and anyone curious about Triodia.

Lepidopteran Families of Biosecurity Concern  --  VISIT
 Views: 60

Updated: Mon 06/05/2017 @ 04:18

An interactive lucid key is presented to assist in recognising families of targeted Lepidoptera of biosecurity concern using morphological characters of the adult. Many existing keys to adult Lepidoptera lack good illustrations of the important characters and this key provides high quality photographs of all the characters used. Easily identifiable features that are visible on set specimens using a stereomicroscope have been chosen in an attempt to avoid where possible, the type of characters requiring manipulation or dissection of the specimen for example, wing venation, apodemes and genitalia.

The range of families included in the key encompasses those exotic species identified by Plant Health Australia (2012), Department of Agriculture (Northern Australia Quarantine Strategy) (2013) and the National Plant Biosecurity Strategy Diagnostic Network (2013). The key has been adapted from Nielsen et al. (1991), Kristensen (1999) and Holloway et al. (1987). Diagnoses were evaluated using data from Bradley (1986), Common (1990), Holloway (2011), Kyrki (1984), Landry (2003), Miller (1991), Nielsen et al. (1996), Solis (2007) and Zborowski et al. (2007).

Diagnostic images were taken by S. Anderson and were prepared from curated specimens using, LEICA DC300 digital camera using Leica DC Twain® version 5.1.10 software. Numerous photographs of each specimen were taken at differing focal planes and these were montaged using Automontage Essentials® 5.020096 ES to produce a single image. Images were taken at 2592 x 1944 resolution and saved in TIFF format.

The authors would like to thank Ted Edwards for his extensive lepidopteran expertise, Matt Taylor, Damian Barnier, James Walker, John Nielsen, Len Willan, David Britton, Thomas Wallenius, You Ning Su, Ying Luo and Luke Halling.
