Several peptides contained in scorpion fluids showed diverse array of biological activities with high specificities to their targeted sites. Many investigations outlined their potent effects against microbes and showed their potential to modulate various biological mechanisms that are involved in immune, nervous, cardiovascular, and neoplastic diseases. Because of their important structural and...

A new species of the genus Diplocentrus Peters, 1861 is described, based on several specimens collected in the Mexican state of Oaxaca. It is characterized by a high telotarsal spiniform setae count (4-5/5:5/6:6/6:6/6-7), and the pectinal tooth counts of 12-15, mode = 13 (male) or 11-13, mode = 12 (female). With the description of this species, the diversity of the genus is increased to 51 spec...

1. Scorpions were starved for 1, 4, 8, and 12 days and then subsequently refed until the sixteenth day. The concentrations of glycogen, amino acid, and protein in the liver were determined to evaluate the effect of starvation and refeeding on these biochemical constituents. 2. The concentration of glycogen decreased gradually but significantly with the progressive days of starvation. After refe...

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).

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...
