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.


Thysanoptera Aotearoa (Thrips of New Zealand)  --  VISIT
 Views: 11

Updated: Thu 10/19/2017 @ 07:56

There have been few studies on the thrips of New Zealand. Most of the information presented in this system is derived from two Fauna of New Zealand volumes (Mound & Walker 1982; 1986). However, much of the data in those two volumes was derived from limited amounts of field work, both in space and time. Particularly missing are biological studies on thrips species that are native to New Zealand, with many of these remaining known from very few specimens.

Only for some Thripidae have there been studies on biology and host-plant range. Teulon & Penman (1990) produced outstanding data on the diversity of plants on which Thrips obscuratus breeds. Martin & Mound (2004) explored the host associations of several species, and Martin (2017) provided good data on the host plants of Panchaetothripinae in New Zealand.

For the many species of fungus-feeding Phlaeothripidae there have been no studies on biology or behaviour, although the sexual dimorphism and male polyphenism many such species exhibit suggests the existence of competitive behaviours.

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: 56

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.
