'''''Caccothryptus larryi''''' is a species of [[Limnichidae|minute marsh-loving beetle]] in the subfamily [[Limnichinae]]. The species was described, alongside five other ''Caccothryptus'' species, by [[Natural History Museum, London|Natural History Museum]] entomologist [[Keita Matsumoto]] in 2021, using specimens gathered in 1953 by [[Harry George Champion]] in [[Haldwani]], India. Both of the ''C. larryi'' specimens featured genital structures distinct from Champion's initial classification of [[Caccothryptus ripicola|''C. ripicola'']]. The species was named after [[Larry (cat)|Larry]], the [[Chief Mouser to the Cabinet Office]] at the British Prime Minister's residence at [[10 Downing Street]].<br />

==Taxonomy==<br />
The [[Limnichidae]] (minute marsh-loving beetle) genus ''[[Caccothryptus]]'' was first described by [[David Sharp (entomologist)|David Sharp]] in 1902.{{sfn|Matsumoto|2021|p=168}}{{Sfn|Yoshitomi|2018|p=138}} In 2014, the genus was divided into five species groups by Carles Hernando and Ignacio Ribera, as part of a reclassification which brought the genus from seven to 23 species.{{Sfn|Hernando|Ribera|2014|p=281}}<br />
<br />
A group of ''Caccothryptus'' specimens were collected in 1953 by forester [[Harry George Champion]] in the [[Haldwani]] division of the [[Kumaon Himalayas]], India. These were labeled as [[Caccothryptus ripicola|''C. ripicola'']], which Champion had previously described in 1923. These were stored at the [[British Natural History Museum]]. In 2021, Natural History Museum entomologist [[Keita Matsumoto]] identified a number of distinct species from these specimens. Two specimens, a male and a female, were identified as a distinct species and became the [[holotype]] and [[paratype]] specimens of ''Caccothryptus larryi''. This new species was placed in the species group typified by ''C. compactus'', and was named after [[Larry (cat)|Larry]], the cat serving as [[Chief Mouser to the Cabinet Office]] at [[10 Downing Street]] since 2011.{{sfn|Matsumoto|2021|pp=168, 176}}<br />
<br />
==Description==<br />
Both ''Caccothryptus larryi'' specimens identified have an [[elytra|elytral length]] of around 2.5&nbsp;mm, and elytral widths of around 2&nbsp;mm. Their [[Prothorax|prothoraces]] both measured around 0.75&nbsp;mm in length and 1.7&nbsp;mm in width. The female paratype is slightly larger in all measurements. The body of ''C. larryi'' is dark brown and covered with long, light yellow [[seta]]e. Its [[Arthropod tarsus|tarsi]] are divided into five segments, of increasing length, with the fifth segment as long as the others combined. It has long, narrow, light brown [[tarsal claws]]. The beetle's head, smooth and punctured, is slightly retracted into its [[pronotum]], and features eleven-segment antennae. Little sexual dimorphism exists between the male and female specimens, beyond a longer fifth abdominal [[ventrite]] on the female.{{sfn|Matsumoto|2021|pp=176–178}}<br />
<br />
The beetle's genitals display a number of differences from their original classification of ''C. ripicola'', which enabled its recognition as a separate species. The [[paramere]]s of ''C. larryi'' have oval-shaped notches on the upper side, as opposed to the semicircular notches of ''C. ripicola''<nowiki/>; they also feature asymmetrical notches on the side of the [[median lobe]], and are generally wider and shorter. The depression between the parameres in ''C. larryi'' are narrow and elongated with a pointed end.{{sfn|Matsumoto|2021|pp=176–178}}<br />
