REPRODUCTIVE BIOLOGY OF LYCHAS These considerations help us to rule out the first possibility. Placentation shifts to nourishment by the ‘queer feeding’ organ piercing the mesosoma in the apoikogenous scorpion Lychas tricarinatus (Mathew, 1962, p. 227; Farley, 2001). Michael Seiter, Mark Stockmann The life history of the parthenogenetic scorpion Lychas tricarinatus (Simon, 1884) from Odisha province, India and supplementary notes on Tityus trivittatus Kraepelin, 1898 (Scorpiones, Buthidae), Zoologischer Anzeiger 270 (Sep 2017): 155–165. Old Timer. It is known to take place under special conditions in many arthropods, but one indication for partheno-genesis is the absence or rarity of males. In the onychophoran Peripatus acacioi , nutrient provisioning begins with histotrophy, continues as placentation, shifts back to histotrophy, and then to histophagy. The second possibility suggested is parthenogenesis. Lychas tricarinatus, Pseudolychas ochraceus, Tityopsis inexpectatus, Tityus columbianus, ... Cloudsley-Thompson (2007) Parthenogenesis in Hottentotta caboverdensis Lourenco & Ythier, 2006 (Scorpiones, buthidae) from the Cape Verde islands, Boletin Sociedad Entomologica Aragonesa, 41:193-196. 简介单性繁殖（Parthenogenesis）属于无性繁殖（Asexual reproduction），是指由配子直接发育成个体，通常可分为专性单性繁殖（Obligate parthenogenesis）、兼性单性繁殖（Facultative parthenogenesis）、雌核发育（Gynogenesis）和杂合发育（Hybridogenesis）。广义的单性繁殖多指孤雌生殖，由卵细胞直接发育成个体。 Clinical Toxinology Resources Website provides information on venoms, toxins, antivenoms, diagnosis, treatment and emergency medicine, for snakebite, spiderbite, envenoming and poisoning by animals, plants, mushrooms.

Michael Seiter and Mark Stockman have recently published an article on life history and parthenogenesis in the two buthids Lychas tricarinatus (Simon, 1884) from Odisha province, India and Tityus trivittatus Kraepelin, 1898 from Argentina. 10x Brachypelma kahlenbergi (1.5cm) – New Mexican: Quick view: 180,00 zł: 10x Nhandu chromatus (1cm) – Brazilian Red and White: Quick view: 80,00 zł Michael Seiter and Mark Stockman have recently published an article on life history and parthenogenesis in the two buthids Lychas tricarinatus (Simon, 1884) from Odisha province, India and Tityus trivittatus Kraepelin, 1898 from Argentina.
