Zootaxa 2025 2025-07-28 5666 2 195 210 Dietrich 2025 [151,317,403,429] Insecta Cicadellidae Loeia Animalia Hemiptera 7 202 Arthropoda species cetacea sp. nov.  ( Figures 1D, 3A–D, 7F)   Diagnosis. This species resembles  L. brevisin having a greatly elongated pygofer but is easily recognized by the arcuate aedeagal shaft lacking paired ventral spines at the base.   Description. Body length of male 5.3–5.6 mm, female 6.5 mm. Head in dorsal view with crown slightly longer medially than next to eye, 1.4× wider at base than medial length. Male pygofer ~6.0× longer than maximum height, without ventral spine. Subgenital plate not extended to midlength of pygofer, laterally convex basal section much shorter than concave distal section. Style relatively long and slender, preapical lobe broadly convex, apex footlike with prominent mesal heel and evenly tapered lateral toe. Aedeagus without dorsal apodeme, shaft moderately robust and long, tubular, evenly arcuate, with recurved ventroapical process divided into pair of finlike branches, gonopore at apex of shaft above distal process. Female sternite VII wider than long, lateral margins tapered in posterior half, posterior margin shallowly concave with light brown median macula.   Etymology. The species name is an adjective formed from the Latin word for “whale” and refers to the distal process of the aedeagus shaped like the flukes of a whale.   Material examined.  Holotype male, THAILAND Petchaburi, Kaeng Krachan NP, Panernthung/km27/water pump, 12º49.151'N 99º22.483'E  950m, Malaise trap  4–11.vii.2008 Chusak& Sirichai& Arkomleg. T4337[ QSBG].  Paratypes: 2 males, THAILAND Petchaburi, Kaeng Krachan NP, Panernthung/ km30; old lavatory, 12º49.484'N 99º21.909'E  970m, Malaise trap  27.vi-4.vii.2008, Sirichaileg. T4339;  1 male, THAILAND Surat Thani, Khao Sok NP Klong Morg Unit, 8º53.725'N 98º39.025'E  87m, Malaise trap  24–31.iii.2009, Pongphanleg. T4477;  1 female, THAILAND Petchaburi, Kaeng Krachan NP, Panernthung/ km27/water pump, 12º49.151'N 99º22.483'E  950m, Malaise trap  11–18.vii.2008, Sirichai& Chusakleg. T4334[all paratypes INHS]. 5244017304 2008-07-04 2008-07-11 2008-07-04 Malaise trap QSBG Chusak & Sirichai & Arkom Thailand 950 12.819183 Kaeng Krachan NP 1 99.37472 Petchaburi 7 202 T4337 1 2 holotype 5244017334 2008-06-27 2008-07-04 2008-06-27 Malaise trap QSBG Sirichai Thailand 970 12.824734 Kaeng Krachan NP 1 99.36515 Petchaburi 7 202 T4339 2 2 paratype 5244017328 2009-03-24 2009-03-31 2009-03-24 Malaise trap QSBG Pongphan THAILAND Surat 87 12.824734 Thani 1 99.36515 Panernthung 7 202 T4477 1 1 1 paratype 5244017302 2008-07-11 2008-07-18 2008-07-11 Malaise trap INHS Sirichai & Chusak Thailand 950 12.824734 Kaeng Krachan NP 1 99.36515 Petchaburi 7 202 T4334 1 1 2 paratype
