The Goldman barbed pocket mouse ( Heteromys goldmani ) is a type of barbed pocket mouse that is found only in the southeast of the Mexican state of Chiapas and in adjacent southwestern Guatemala .
features
The Nelson pocket mouse reaches a head-trunk length of 14.7 centimeters on average, the tail is 19 centimeters long on average. The average ear length is 18 millimeters and the average hind foot length is 36 millimeters. It is therefore a relatively large species of the genus, there is no significant difference between the sexes. The fur of the adult animals is rough and contains individual stiffened, soft and spiky hairs on the back and stomach. The back fur is gray to slate black with uneven ocher-colored speckles and without a sand-colored side line, the belly side is white. The ears do not have a white border.
The front areas of the soles of the hind feet are bare and have six tubercles. The tail is significantly longer than the length of the head and trunk and has thin hairs, the top is darker than the underside.
The karyotype consists of a diploid chromosome set of 2n = 60 chromosomes (FN = 76).
distribution
The range of the Goldman barbed pocket mouse is restricted to the southwest of the Mexican state Chiapas as well as the adjacent northwest Guatemala in the area of the Sierra Madre del Sur , where the species lives in higher mountain areas. The height distribution ranges from about 45 to about 1860 meters.
Way of life
The Goldman barbed pocket mouse lives in the wooded areas of the Pacific mountain ranges of the Sierra Madre del Sur . The species is nocturnal and living on the ground and lives in pairs or small groups in their burrows. Otherwise, almost no information is available about their way of life.
Systematics
The Goldman pocket mouse is classified as a separate species within the genus of the pocket mouse ( Heteromys ), which consists of 16 species. The first scientific description comes from Clinton Hart Merriam from 1902, who already introduced it as Heteromys goldmani . The animals available to him for the first description came from a zoological excursion by the American zoologists Edward Alphonso Goldman and Edward William Nelson from the Bureau of Biological Survey of the American Department of Agriculture in Mexico. Goldman and Nelson made a total of about 800 individuals of different species of barbed pocket mice available to Merriam, through which he could describe 20 different species and subspecies of the genus in his publication. The type locality of the Goldman barbed pocket mouse was given as Chicharras , Chiapas. Merriam named this species after Goldman and the Nelson barbed pocket mouse ( Heteromys nelsoni ) after Nelson.
The species is common with the Desmarest spiny mouse pocket ( Heteromys desmarestianus ), the mountain-sting pocket mouse ( Heteromys oresterus ) and the cloud forest spiny mouse pocket ( Heteromys nubicolens ) of the desmarestianus associated group within the sting heteromyidae. At times it was added to the Desmarest pocket mouse as a subspecies due to several anatomical features, but currently it is again considered as an independent species.
Apart from the nominate form, no further subspecies are distinguished within the species .
Status, threat and protection
The International Union for Conservation of Nature and Natural Resources (IUCN) considers the Goldman barbed pocket mouse to be a synonym for the Desmarest barbed pocket mouse and is therefore not listed. There is heavy logging within the distribution area.
