Reference excerpt

Tisamenus summaleonilae is a species of stick insect in the family Heteropterygidae native to the northeast of Philippine island of Luzon.

Description Tisamenus summaleonilae is a small, slender, and sparsely spined Tisamenus species, of which only two adult males are known so far. The species describers only reported the length of the holotype specimen at 33.68 millimetres (1.326 in). In contrast to the equally slender, but significantly larger males of Tisamenus polillo, they lack the large, three-part spines (pronatals) on their pronotum. These are very small and rather bumpy. The anterior edge of the pronotum is laterally extended, like a tooth. Unlike males of Tisamenus polillo and the similarly small males of Tisamenus kalahani, their mesothorax and metathorax are not parallel, but widen posteriorly, giving the entire thorax a wedge-shaped appearance. The triangle on the mesonotum, typical of the genus, is large in males of Tisamenus summaleonilae, reaching almost two-thirds of the mesonotum length. The two posterior edges of this triangle are clearly raised. There are no spines on the mesopleura and only very small spines on the metapleura above the coxae (supracoxal spines). There are no spines on the abdomen.

Distribution, discovery and taxonomy The only known specimens of the species are two males from the Isabela Province in northeastern Luzon, more precisely from Sitio Apaya, in Barangay Dibuluan, part of the municipality of San Mariano. They were collected there in June 2005 by A.C. Diesmos at an altitude of about 200 metres (660 ft). Ireno L. Lit Jr. and Orlando L. Eusebio described Tisamenus summaleonilae in the same year based on these specimens, together with Tisamenus kalahani. Both specimens are deposited in the Entomological collection of the Museum of National History of the University of the Philippines Los Baños (UPLB), one as the holotype, the other as the paratype. Lit and Eusebio assigned both Tisamenus summaleonilae and Tisamenus kalahani to the previously monotypic Polillo group established by James Abram Garfield Rehn and his son John William Holman Rehn. The species name "summaleonilae" is a combination of the Latin adjective "summus", meaning high, and the first or given name of Dr. Leonila A. Corpuz-Raros, who, like the described animals, comes from Isabela Province and is a highly valued mentor to the authors. The combination "summaleonilae" is intended to emphasize that Dr. Raros deserves the highest honor for her achievements as a scientist, systematist, and acarologist.

Worked examples

Example 1 — a first encounter with Tisamenus summaleonilae

Start with the simplest possible case. Write down what Tisamenus summaleonilae 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 summaleonilae 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 summaleonilae 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 summaleonilae

In research: Tisamenus summaleonilae 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 summaleonilae 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 summaleonilae 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 summaleonilae 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.
