They look like tiny frogs, jump like them too — and for 45 years, no new African member of their group had been found. That changed in 2026.
Dr. **Alvin Helden**, an entomologist at **Anglia Ruskin University (ARU)** in Cambridge, England, has announced the discovery of **seven new species** of frog-like leafhoppers deep in the tropical rainforests of Uganda's **Kibale National Park**. The findings have been published in the journal ***Zootaxa***.
The insects belong to the genus ***Batracomorphus*** — a name that comes from the Greek words for 'frog-shaped'. And the name fits. These tiny creatures are usually bright green with large, bulging eyes, and they move by launching themselves through the air with powerful hind legs that fold alongside their bodies — giving them the unmistakable profile of a miniature frog, even mid-jump.
**A 45-Year Gap**
Before Dr. Helden's study, scientists had catalogued just **375 species of Batracomorphus worldwide**, with only two recorded in the United Kingdom. The last time new African members of the group were described in scientific literature was **1981** — making these seven species the first new African Batracomorphus in over four decades.
All seven were collected using **light traps** positioned in rainforest areas **more than 1,500 metres above sea level** in Kibale National Park. The traps attract night-flying insects, and among the catch were these stunning, previously unnamed creatures.
**The Lock-and-Key Problem**
One of the most difficult parts of the research — and the reason so many leafhoppers remain undescribed — is that the insects in this genus look almost **identical on the outside**. Their green bodies, large eyes, and jumping legs vary very little between species.
To definitively confirm new species, scientists must examine the insects' **genital structures**. In leafhoppers, reproduction works on a precise 'lock-and-key' system: the male genitalia have a unique shape that corresponds exactly to the female structures of the same species. This prevents hybridisation and ensures reproductive isolation — the biological definition of a distinct species.
These intricate structures are made from the same hard material as the insects' exoskeleton. They're durable, distinctive, and the only reliable way to tell species apart.
For Dr. Helden, this painstaking work paid off — seven times over.
**Named for a Mother**
Among the seven new species, one stands out with a particularly poignant name: ***Batracomorphus ruthae*** — named in honour of **Dr. Helden's late mother, Ruth**.
It's a tradition as old as taxonomy itself — naming new discoveries after people who mattered. A tiny frog-shaped insect, previously unknown to science, now carries forward the memory of a mother. Few legacies feel quite so quietly extraordinary.
**Why Leafhoppers Matter**
Leafhoppers may not have the charisma of pandas or the drama of apex predators, but they are ecologically significant. Dr. Helden describes them as 'beautiful, endearing creatures'. While some species can be agricultural pests — associated with crops like maize and rice — leafhoppers as a whole are important parts of rainforest ecosystems, serving as herbivores, prey, and biodiversity indicators.
Discovering seven new species in a single study is a reminder that even well-studied parks like Kibale still harbour secrets. The world's rainforests contain millions of species yet to be named — and each discovery tells us something about the richness of the life we are only beginning to understand.
For Dr. Helden, this latest discovery follows his 2022 finding of *Phlogis kibalensis* in the same park — a rare leafhopper with a distinctive metallic sheen. It seems Kibale keeps giving.
