Camaricus maugei is a species of crab spider in the family Thomisidae. It has a wide distribution across tropical Asia, ranging from India to Vietnam, and including Indonesia (specifically Sumatra, Java, and Krakatau). ^[1]

Etymology

The species epithet maugei is a patronym honoring René Maugé de Cely. ^[2]

Distribution

C. maugei has been recorded from India to Vietnam, and throughout much of Indonesia, including the islands of Sumatra, Java, and Krakatau. ^[1]

Description

Based on the original descriptions, C. maugei is a crab spider with distinctive coloration patterns. The abdomen is oval-shaped and notably larger at the posterior end, appearing black with a yellow or reddish cross-like marking in the middle of the dorsal surface. Along the transverse bar of this cross, near the spinnerets, are two deeply sunken, very distinct points. ^{[2] [3]}

The cephalothorax is brilliant red and not flattened on the sides, with a red sternum. The chelicerae are wedge-shaped, flattened, and black with a large red spot on the side. The pedipalps are reddish with black tips, though somewhat swollen. The legs show sexual dimorphism in coloration: the thighs and tibiae of the first two pairs are black, while the tarsi are whitish-yellow with black markings.
