The male of Megacormus granosus (Gervais, 1844) with comments on its hemispermatophore (Scorpiones, Euscorpiidae)
نویسندگان
چکیده
The male of Megacormusgranosus is described for the first time and the female redescribed. A homology scheme proposed recently is applied to hemispermatophore structures. The specimens were collected in an oak forest from Pico de Orizaba Volcano at an average altitude of 2340 m. All adult males were collected by pitfall traps, whereas all adult females and both sex immatures were collected using Berlese funnels, suggesting that males are comparatively more mobile within the leaf litter layer, probably due to mating season.

Complex male genitalia (hemispermatophores) are not diagnostic for cryptic species in the genus Euscorpius (Scorpiones: Euscorpiidae)
Genital morphology is often used as a key character for distinguishing species in many arthropod groups. Regarding scorpions, male genitalia (hemispermatophores) have been increasingly used in species descriptions. In the present study we analyse hemispermatophores of four Central European species of Euscorpius Thorell, 1876, and those of Euscorpius flavicaudis (De Geer, 1778) from southern Fra...

Two new species of Euscorpius Thorell, 1876 (subgenus Euscorpius s.str.) (Scorpiones: Euscorpiidae) are described based on morphology and the COI DNA barcoding marker: E. deltshevi sp. n. from northern Bulgaria and neighbouring Serbia (formerly reported as E. carpathicus) and E. solegladi sp. n. from southwestern Bulgaria and neighbouring Greece (formerly reported as E. hadzii).

A new species, Chactas moreti sp. n., is described from Ecuadorian Amazonia. It can be distinguished from Chactas mahnerti Lourenço, 1995, the other known species of this genus from Ecuador by its smaller body size, distinct morphometric values, overall darker blackish-brown coloration, totally smooth vesicle, and a concave anterior margin of carapace. This is the second confirmed record of the...

Among the genera of the subfamily Scorpiopinae Kraepelin, 1905 Alloscorpiops remains rather discrete. Only recently new species were added to this genus, increasing its number from two to five. Therefore, species of Alloscorpiops remain rare. One remarkable new species, Alloscorpiopstroglodytes sp. n., is described on the basis of a single male specimen collected inside a cave from Song Thanh N...
متن کاملNotes on the scorpions (Arachnida, Scorpiones) from Xizang with the redescription of Scorpiops jendeki Kovařík, 2000 (Scorpiones, Euscorpiidae) from Yunnan (China)
Until now, there are 26 scorpion species of 7 genera of 5 families recorded in Xizang (China). Xizang Autonomous Region (Tibet) is the scorpion biodiversity richest area in China (53 scorpion species of 12 genera of 5 families), also the highest altitude habitat of scorpions in the world. We present information of type specimens, an identification key of the scorpion species from Xizang, the di...
