I'm a NERC funded PhD candidate at the University of Exeter with the GW4+ DTP, studying Carabus intricatus. The project focusses on ecology, conservation, and biogeography. I additionally have a very keen interest in spider systematics and taxonomy, I have ongoing projects in Madagascar and Paraguay. Through the Belgian npo BINCO, i am the Research Director of the SpiDivErse research group- focussing on discovering new species from imperilled and highly biodiverse regions.

Two new species of Phyxelididae are described from southern Africa: Xevioso cepfi sp. nov. (♂♀), from mountains in the Niassa Province of northern Mozambique, and X. megcummingae sp. nov. (♂♀), from urban Harare, northern Zimbabwe and the Viphya Mts in Malawi. They represent the northernmost localities of the genus. An identification key, partially...
A new genus and two new species of ant-resembling castianeirine spiders are described from the Neotropics. Grismadox gen. nov. comprises four species: Grismadox baueri sp. nov., and Grismadox mazaxoides (Perger & Duperré, 2021) comb. nov. from Bolivia, and Grismadox karugua sp. nov. (type species) and Grismadox mboitui (Pett, 2021) comb. nov. from...
A new species of the castianeirine spider genus Copa Simon, 1885, is described from northwestern Mahamavo region in Madagascar. Copa sakalava sp. nov. (♂♀) is illustrated and diagnosed against continental Afrotropical congeners.
Patelloceto Lyle & Haddad, 2010 is a small genus of dark sac spiders from the Afrotropical region, diagnosed by very distinct morphology of the genitalia, males with femoral, patellar, and tibial apophyses, females with a broad membranous median septum separating the small lateral spermathecae, and long, oblique, lateral epigynal hoods flanking cop...
A new ant-like spider species of the subfamily Castianeirinae, Mazax akephaloi sp. nov., representing the second species of Mazax recorded from South America, is described from the Bolivian orocline and the Paraguayan Chaco region. The new species superficially resembles Mazax ramirezi Rubio & Danişman, 2014, but can be distinguished from this spec...
The holotypes of the three remaining valid species of South American jumping spiders described by H. D. Badcock are re-evaluated, following their recent examination and recuration. Plexippus luteus Badcock, 1932 was described based on an immature specimen which is not identifiable to species level. Prószyński (2017) regarded it as an "unrecognisabl...
Based on male specimens, two new sympatric species of Actinopus Perty, 1833 from Paraguay: Actinopus tetymapyta sp. nov. and Actinopus tasneemae sp. nov. are described. The remarkable discovery of two species occurring sympatrically in the humid Chaco ecoregion of Paraguay demonstrates the species richness of the genus.
A new species of ant-resembling sac spider of the subfamily Castianeirinae, Grismadox elsneri sp. nov., is described from the Sub-Andean area of the Bolivian orocline. The species was collected from savanna grass along the edges of the Chiquitano forest and is a putative mimic of the carpenter ants Camponotus cf. crassus or C. cf. blandus.
We report on three new country records of tiger beetles in Paraguay and an additional 18 new departmental records based on specimens in Paraguayan collections. We also document substantial increases to the knowledge on distributions of numerous species in the country through additional specimen records. The first tiger beetle records from south-wes...
Two Neotropical species of the subfamily Castianeirinae are treated herein. Castianeira spinipalpis Mello-Leitão, 1945 was described from a single female specimen; we provide a redescription of the female and the male is described for the first time. The species is newly recorded from Paraguay and Bolivia. Also, Myrmecotypus rubioi sp. nov. is desc...
The castianeirine spider genus Myrmecotypus O. Pickard-Cambridge, 1894 is reported from Paraguay for the first time, with the description of a new species, Myrmecotypus mboitui sp. nov. (♂♀) from the Ñeembucú Wetlands Complex of southwestern Paraguay. The species belongs to a small group of Myrmecotypus with elongated and constricted abdomens. Illu...
The female of Otiothops inflatus Platnick, 1975 is described for the first time. The species is rediagnosed based on new material from Paraguay. A possible synonymy, with O. inflatus having priority over O. payak Grismado & Ramírez 2002, is discussed .
Knowledge on spiders in Paraguay is abysmal, even in Salticidae, the most diverse spider family. Prior to this study, 40 species were registered for Paraguay, which may be underestimating the true species diversity in the country by five times or more. This study provides a first baseline for jumping spiders in Paraguay from evaluation of three sal...
Riggia are freshwater cymothoids known to parasitize fish throughout South America. In Brazil, a male R. cryptocularis was previously found parasitizing the characid Odontostilbe paraguayensis, which was thought to be an accidental host given its small size and known Riggia reproductive requirements. Here, 759 O. paraguayensis and O. pequira specim...
We provide the first confirmed record of the zodariid genus Cybaeodamus Mello-Leitão 1938 in Paraguay from both males and females of C. meridionalis Lise, Ott & Rodrigues, 2009. We illustrate the species and provide an updated map of its distribution in South America. Due to a distinct lack of sampling for spiders in Paraguay, this paper doubles th...
Sixteen species of Eburiini are recorded from the colección Invertebrados Para La Tierra Entomología, IBIS and MNHNP collections in Paraguay, including the description of Eburodacrys mcgavini nov. sp. from a specimen collected in Presidente Hayes department. Four other species are new records from Paraguay and eight are new departmental records in...
The first confirmed locality record for Gypogyna forceps Simon, 1900 (Salticidae: Scopocirini) is reported from Paraguay, from the southwestern Ñeembucú department. Commentary is provided on the significance of the specimen, and an updated map of the distribution of this species in South America is provided.
Microendemic species are of great conservation concern due to their vulnerability to stochastic events and environmental change. Therefore, understanding the basic ecology of such organisms is integral to future efforts to conserve them. Here, we present the first ecological study of the only known population of Ocyale ghost Jocque & Jocqué 2017-th...
Morphological abnormalities in anurans are known to be globally widespread. Here, we report on six individual anuran morphological abnormalities from four Paraguayan departments. We briefly discuss potential causal agents and highlight the need for further research into this topic in Paraguay.
