From storage to delivery: sperm volume and number of spermatozoa inside storage organs and ejaculates in males ofTimogenes elegans(Scorpiones: Bothriuridae)

Abstract: Abstract. Sperm competition influences the evolution of many reproductive traits such as gonads, sperm or genitalia. Many sperm competition analyses concentrate in testes and ejaculates. Among arachnids, scorpions constitute an intriguing taxon for examining sperm production and usage. For example, in the family Bothriuridae the females of Timogenes elegans Mello-Leitão, 1931 accept more than one male per reproductive season and males produce spermatozoa continuously, storing them inside two elastic storage or… Show more

“…Koch, 1842), Brachistosternus ferrugineus (Thorell, 1876), Timogenes elegans , and Urophonius brachycentrus (Thorell, 1876), were investigated in more detail. The reproductive biology of these species has been extensively studied (Vrech, 2013;Vrech et al, 2014Vrech et al, , 2018Vrech et al, , 2019Romero-Lebron et al, 2019;Oviedo-Diego et al, 2019, 2020Olivero et al, 2015Olivero et al, , 2019Olivero et al, , 2021 and fresh material was more readily available compared to other taxa.…”

“…One of the main factors that determine male reproductive quality in some invertebrate species is body size: small males produce lower sperm quantities than larger males and could limit egg fertilization by providing smaller ejaculates to females (e.g. Wiernasz et al, 2001;Ceballos-V azquez, Rosas & Racotta, 2003;Sato et al, 2006;French & Hammack, 2012;Butler et al, 2015;Pugh et al, 2015;Alavi et al, 2016;Vrech et al, 2018). Moreover, small males may have a limited capacity to increase spermatophore volume when mating with large females.…”
