Pintomyia falcaorum

Pintomyia falcaorum is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pintomyia falcaorum rather than just read about it. In short: Pintomyia falcaorum is an extinct species of sandfly in the moth fly subfamily Phlebotominae. P. falcaorum is solely known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.

Key takeaways

Pintomyia falcaorum belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Pintomyia falcaorum to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Pintomyia falcaorum from memory before moving on to harder problems.

Reference excerpt

Pintomyia falcaorum is an extinct species of sandfly in the moth fly subfamily Phlebotominae. P. falcaorum is solely known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.

History and classification The species is known solely from the holotype specimen, a complete male fly. The specimen is currently residing in the phlebotomine sandfly collection in the Centro de Pesquisas René Rachou. The centro is part of the Oswaldo Cruz Foundation in Minas Gerais Brazil. The specimen was collected from an unidentified amber mine in the Cordillera Septentrional north of Santiago de los Caballeros. The specimen was first studied by sandfly researchers Reginaldo Peçanha Brazil and José Dilermando Andrade Filho. Brazil and Andrade Filho published their 2002 type description in the journal Memórias do Instituto Oswaldo Cruz. The specific epithet "falcaorum" was coined by the author in honor of Alda and Alberto Falcão, to recognize their contributions to Phlebotominae understanding.

Description A number of features in the specimen indicate its placement in the moth fly subfamily Phlebotominae and the tribe Lutzomyiina. The specimen displays pre-apical bristles, and four spines on the style, these features combined with the AIII flagellomere being over half the length of the head. This combination of features indicates a placement in the genus Pintomyia. Within the genus, it is placed in the subgenus Pifanomyia, based on the posterior femurs lack of spines, but the species does not resemble the known modern species-group series. The light coloration of the abdomen on P. falcaorum is unlike the P. monticola series, while the P. pacae series have papillae on the AXIII segment. Papillae on the AV segment of the P. verrucarum, P. serrana and P. townsendi mark them as different from P. falcaorum. Like Pintomyia falcaorum the Dominican amber fly species Pintomyia paleotownsendi has a Sc vein that is free while the Sc meets the costa vein in P. paleotrichia. In contrast P. brazilorum, P. killickorum, Lutzomyia filipalpis, L. miocena, L. paleopestis, L. schleei, and L. succini all possess an Sc which meets the R1 vein. The presence of a forked Sc vein in the wings, found in some Lutzomyia species including L. adiketis, is unique among the described species of sandflies from Dominican amber. Living members of the Phlebotominae suck blood from vertebrates, and P. falcaorum is presumed to have done so as well. However, the host(s) of this species has not been identified at this time.

Worked examples

Example 1 — a first encounter with Pintomyia falcaorum

Start with the simplest possible case. Write down what Pintomyia falcaorum claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Pintomyia falcaorum 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 Pintomyia falcaorum 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 Pintomyia falcaorum

In research: Pintomyia falcaorum appears in biology 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 Pintomyia falcaorum 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: Pintomyia falcaorum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dominican amber, Fossil taxa described in 2002, Insects described in 2002, so understanding it makes those chapters shorter.
In everyday life: Look for Pintomyia falcaorum 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.
