Luís Mendes, as he was known in academic life, was born in Lisbon, Portugal, June 22, 1946. He passed away in the same city on September 14 2023.
Luís graduated in biology in 1971 from the University of Lisbon, the institution where he pursued his academic career (PhD in 1983, Aggregation in 1987) and where he taught from 1970 to 1994. From 1990 onwards, Luís moved to the Tropical Research Institute (IICT), where he became Head Researcher in 1995. After retiring in 2014, he continued working intensively – devoting most of his energy to the study of the butterflies of Angola and the islands of São Tomé and Príncipe. He did this as invited researcher at CIBIO (Research Centre in Biodiversity and Genetic Resources from the University of Porto) and as invited curator at MUHNAC (the Portuguese National Museum of Natural History).
His research life was devoted to the study of insects. Luís participated in the creation of the Portuguese Entomological Society in 1978, where he provided editorial duties until his death. He published more than 200 papers covering the building blocks required to grasp the most diverse animal group: taxonomy, phylogeny, distribution, and biogeography. He was the first author of the massive three-volume work ‘Butterflies of Angola’, of which only the first volume has been published, with the second in production, and with Luís busy completing the third – together with his long-time close academic partner-in-arms António Bivar de Sousa – until a few weeks before he passed away. He also completed the book ‘The Butterflies of São Tomé and Príncipe’ that will be published in 2024, sadly without Luís present to see the final result. Although most people will recall Luís for his expertise in butterflies, he was considered a world authority in the former order Thysanura – now split in Archaeognatha (jumping bristletails) and Zygentoma (silverfish).
Luís described more than 220 species and subspecies, 57 genera and subgenera, eight subfamilies and one family of insects new to science (Orders Microcoryphia, Zygentoma and, in collaboration, Phthiraptera: Mallophaga and Lepidoptera: Saturnoidea and Papilionoidea).
Luís was a keen fieldworker. During his military service, in the early 1970s, Luís coordinated oceanographic cruises in the Macaronesia islands. From 1980 onward, he participated in and often coordinated several zoological missions, mainly to tropical and subtropical areas, including São Tomé e Príncipe (which he visited multiple times), Angola, Guinea-Bissau, and China (Macau). In Portugal he was particularly interested in the archipelagos of the Azores, Madeira, and Savage islands, but he also worked elsewhere in Europe. He was adept of spreading the word – having curated several exhibitions on insects and participating actively in many outreach actions for the general public and to younger audience in particular. His enthusiasm must have certainly brought many young minds into the field of biodiversity.
Many colleagues paid homage to Luís’ dedication and contribution to science by naming species after him, including one genus of Microcoryphia, ten species of other insect orders (Diplura, Microcoryphia, Zygentoma, Dermaptera, Phthiraptera: Mallophaga, Coleoptera, Strepsiptera and Diptera), and even a snake from the Gulf of Guinea island he seemed to love above all: the Príncipe brown house snake Boaedon mendesi.
Luís Mendes was extremely supportive of the efforts that led to the creation of the Gulf of Guinea Biodiversity Centre (GGBC), of which he was a founding member. From its inception, the GGBC attributed Luís Mendes an Honorary Membership as a way of acknowledging his major contributions to the knowledge of the biodiversity of the Gulf of Guinea islands. GGBC founding member Jorge Palmeirim, Professor at Faculty of Sciences of the University of Lisbon where Luis Mendes studied and started his academic and teaching career, summarises well the feelings of all of those who were lucky to meet Luís: “Luís was one of my greatest professors! As his student, I often found myself motivated and inspired by his infectious passion for nature, especially his love for the tiniest creatures. My memories of him will always be marked by his warm smile, as he recounted his latest adventure or discovery with childlike enthusiasm. Wonderful memories indeed…”
