Reference excerpt

Tisamenus malawak is a species of stick insect in the family Heteropterygidae native to the Philippine island of Camiguin.

Description Tisamenus malawak is a small and stocky Tisamenus species. The only described male is 29 millimetres (1.1 in) long. Morphologically, it resembles Tisamenus alviolanus from Negros and Tisamenus cervicornis from Luzon, but can be distinguished from these two species, as well as from all other Tisamenus species, by its very broad basal shape. Its mesothorax is significantly shorter than it is wide at the posterior edge. The head and body structure are poorly developed. The pleural spines above the coxae on the meso- and metanotum (meso- and metapleural supraoxals) are directed approximately 45° backwards.

Distribution Tisamenus malawak is the southernmost Tisamenus species. According to the collection label, the only known specimen to date comes from the island of Camiguin, north of Mindanao. According to Albert Kang, who collected the specimen on January 20, 2014, it comes from Mindanao, but this could also mean that it comes from the Mindanao island group, to which Camiguin belongs.

Taxonomy Frank H. Hennemann described the species in 2025 as part of a taxonomic revision of the genus Tisamenus based on a single male. This specimen, originally from the collection of Thies H. Büscher in Kiel, was deposited as the holotype in the Zoological Museum of Kiel University (ZMK) after its description. Büscher had received it from Thierry Heitzmann and Albert Kang. The species name "malawak" chosen by Hennemann means "broad" or "wide" in Filipino and refers to the remarkably stocky physique of this small species, in which the mesothorax is significantly shorter than the width of this segment at its posterior edge. Sarah Bank et al. also included 14 samples from various species of the genus Tisamenus in their 2021 study on the relationships within the Heteropterygidae, based on genetic analyses. Among them was a sample from the still undescribed Tisamenus malawak, then known as Tisamenus sp. 9 (Camiguin). For this purpose, the left midleg of the later holotype, still in Büscher's collection, was removed to extract DNA from it. The results showed that Tisamenus malawak is the sister species of Tisamenus hystrix and, together with this species and Tisamenus clotho, Tisamenus cervicornis and the even newly described Tisamenus heitzmanni (see cladogram of Tisamenus).

Worked examples

Example 1 — a first encounter with Tisamenus malawak

Start with the simplest possible case. Write down what Tisamenus malawak claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tisamenus malawak before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tisamenus malawak ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tisamenus malawak

In research: Tisamenus malawak appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tisamenus malawak in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tisamenus malawak is common in secondary-school and first-year university syllabi. It links to neighbouring topics Insects described in 2025, Phasmatodea, so understanding it makes those chapters shorter.
In everyday life: Look for Tisamenus malawak outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
