The military ground snake Erythrolamprus miliaris is a species of snake in the family Colubridae. The species is endemic to South America. In Gans gave it the common name common water snake.

South American common names for E. The original generic name, Coluber , was indicated to mean "common snake". Six subspecies are recognized, including the nominotypical subspecies. The subspecific name , merremi is in honor of German herpetologist Blasius Merrem.

Dorsally , it is pale olive-brown or yellowish, with each smooth dorsal scale edged with black. Ventrally, it is uniformly yellow. They include amphibians also, eggs and tadpoles , invertebrates, lizards , fish , birds , and small rodents. However, there is little information on its feeding habits. Sexual maturity in snakes is regarded by experts as difficult to determine; however, it can be assessed by the snout-vent length SVL.

Sexual maturity is positively correlated to mean body size. Males were considered mature if the testes were large and turgid or if the deferent ducts were opaque and convoluted, indicating the presence of sperm. Females in the subspecies populations of Erythrolamprus miliaris meremmi and Erythrolamprus miliaris orinus were seen to be greater in body size than the males.

There is sexual dimorphism with respect to size of adult Erythrolamprus. Adult females are larger in the subspecies merremi and orinus. They were seen to be larger than the adult males. The sexual dimorphism index was seen to be similar in the geographic areas of the northern coastal Atlantic forest, southern coastal Atlantic forest, northern inland Atlantic forest and southern inland Atlantic forest.

This was indicative of no geographic variation in sexual size dimorphism. It is believed that body size may differ either because of local genetic modification or direct phenotypic effect of food availability on the growth rates. In addition to body size, the comparison of head size in E.

Head size is considered to be associated with inter-sexual dietary divergence. With respect to reproductive output in the northern and southern coast Atlantic forest, and the northern and southern inland forest, the reproductive output recorded for Erythrolamprus miliaris orinus and Erythrolamprus miliaris merremi were determined via number of eggs, size of eggs, and number of neonates. The mean egg volume in the southern coast Atlantic forest was seen to be the largest of the four regions.

The reproductive frequency was lower in the northern coast Atlantic forest than the other regions. Parasitism is not understood very well in the context of snake ecology. The only inferences that have been made are those with the influence on natural populations. It is thought to be related to the snakes feeding behavior and immunological resistance. Two parasites were discovered in the subspecies orinus and merremi. The first were adults of Ophidiascaris sp. Nemaotoda in the stomach.

Also Cystacaths of Oligatanthorynchus spira Acanthocephala were in the peritoneum. The prevalence found in the four different regions, northern and southern coastal Atlantic forest and northern and southern inland Atlantic forest, were observed in Pizatto's and Marques' study.

The lowest prevalence was seen in the northern coastal Atlantic forest. The level of parasite infestation did not differ between the males and females. Female reproductive status was unaffected by the level of infection, nor was the number of eggs she carried.

The male reproductive system was unaffected by the level of infestation as well. In , Erythrolamprus miliaris intermedius was classified by Henle and Ehrl. However, they made a mistake. It was later discovered by Dixon and Tipton, through various comparisons of body composition, that Erythrolamprus miliaris intermedius was actually Erythrolamprus reginae. Erythrolamprus miliaris is seen in the Atlantic forest of South America, the rainforest in eastern Brazil, and the semi deciduous forests in southeastern Brazil.
