038C87A8FFA9AC07FFDD7D34FA8D3FB5.taxon	conservation	Status and Conservation. Classified as Endangered on The IUCN Red List. All known localities of Golden-rumped Sengis occur in less than 5000 km? *, and habitats are severely fragmented. Extent of habitat and number of mature individuals were last assessed in continuing decline. The most important site for the Golden-rumped Sengi is Arabuko-Sokoke Forest Reserve near the coast of Kenya that provides 372 km * of habitat. Population estimates for Arabuko-Sokoke decreased by about 30 % between 1993 and 1996 and dropped another 9 % to less than 13,000 individuals by 2008. No population surveys have been done since 2008. All other localities of occurrence are within 100 km of Arabuko-Sokoke and support much smaller populations. Within Arabuko-Sokoke, logging is a major threat that reduces canopy cover and density of leaflitter. Outside Arabuko-Sokoke, clearing of scrub and woodland, fire, and agricultural encroachment are principal threats. Subsistence hunting of the Golden-rumped Sengi was documented in the 1990 s, with an estimated 3000 individuals harvested per year in Arabuko-Sokoke. Given the increase in human population in coastal Kenya, hunting pressure might be increasing.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.

There is no evidence of sexual dimorphism in body size. Tail of the Chequered Sengi is ¢. 90 % of head-body length and is proximally thick and distally tapered; tail is nearly hairless, with white band near tip. Dorsum ranges from buff to dark brown, with orange tones. On each side of mid-dorsal axis, three longitudinal stripes run from mid-back to near base oftail. Left and right lines closest to mid-dorsal axis are nearly continuous, but the more lateral lines are often broken into pale and dark spots. This distinctive pattern of lines and spots on rump and back is diagnostic, if tail is only white near tip (not from base to tip). In some subspecies, darker background of rump and back hair obscures stripes so that only a faint pattern is visible. Venter is off-white to light yellow. Hair on head and snout are brown to cream. Pinnae are hairless, with buff colored skin. Snoutis long and flexible. Females have two posterior, two intermediate, and no anterior nipples; males have no nipples. Four digits are present on each manus and pes; pollex and hallux are absent. Fifth manual digit is relatively short and has only two phalanges. Post-anal gland is well developed, and pectoral gland is absent. Dental formula is I 0 - 1 / 3, C 1 / 1, P 4 / 4, M 2 / 2 (x 2) = 34 - 36.

There is no evidence of sexual dimorphism in body size. The Etendeka Round-eared Sengi is round-bodied, with a round face. Tail length is ¢. 95 % of head-body length, short relative to other species of Macroscelides. Pinnae are broad, rounded, and shorter than on most species of Elephantulus. Snout is long, thin, and flexible. Hairis long, soft, and silky. Dorsal and lateral pelage is graybrown, with obvious rust-colored tinge, most prominent on face, rump, and tail. Hairs at distal end oftail are slightly longer and form rust colored tuft. Venteris off-white. Small but distinct patch of rust-colored fur occurs on each side of anus. Skin color of pinnae and limbs is pink, and hair on these areas is sparse. Prominent subcaudal gland, rust-colored fur, distinct perianal pattern, and pink skin of ears and limbs are diagnostic. There is no distinct eye-ring as occurs on many species of soft-furred sengis. Females have two anterior, two intermediate, and two posterior nipples; males have no nipples. Five digits are present on each manus and pes. Pectoral gland is absent, and subcaudal gland is highly developed. Dental formulais 13 / 3, C 1 / 1, P 4 / 4, M 2 / 2 (x 2) = 40. Molariform teeth are more hypsodont in species of Macroscelides than in other extant species of sengis. Canine sizes are subequal to adjacent teeth. Auditory bullae are hyper-inflated. Several bilateral pairs of palatal foramina are present. Karyotype is unknown.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.

In areas with harsh climates (e. g. high plains of Algeria), first births occur near the end of April, but in more temperate climates (e. g. near coast in Tunisia), first births begin in March. Reproduction is probably constrained by long gestation and relatively short period of warm weather in North Africa (compared with climates of sub-Saharan species). Populations at high elevations might produce one litter per year, but at lower elevations, two litters per year are possible. Litters most frequently have two (58 %) and three (31 %) young and less frequently one and four (maximum of any species of sengis).

038C87A8FFADAC03FAD97D45F60C3ED3.taxon	description	Descriptive notes. Head-body 122 - 148 mm, tail 144 - 167 mm, ear 23 - 25 mm, hindfoot 34 - 39 mm. No specific data are available for body weight. Tail of the Somali Sengiis relatively long at ¢. 120 % of head-body length, pinnae are broad and upright, and snout is long, thin, and flexible. Similar phenotypes of the Somali Sengi and the Rufous Sengi (E. rufescens) are probably evidence of sister-species relationship. Dorsum is pale brown to pink-gray, with tone that is overall less yellow than in the Rufous Sengi. Behind each ear, patch of dark buff hair extends onto nape of neck. Venter is gray-white, with hairs that are dark gray to black for basal one-third and white for distal two-thirds. Pectoral gland is fringed with distinguishable short white hairs. Tail hairs are white, with brown tips. Longer hairs near tip oftail form small tuft. Pinnae are nearly hairless, and rhinarium is hairy below. Narrow white eye-ring is present, with thin post-ocular patch of dark brown hair that intrudes on eye-ring and extends posteriorly. White ‘ brow’ branches from the eye-ring and sweeps superiorly adjacent to post-ocular patch and extends to near base of ear. Hairy inferior rhinarium and spectacled pelage pattern around eyes are traits shared only with the Rufous Sengi. Females have two anterior, two intermediate, and two posterior nipples; males have no nipples. Five digits are present on each manus and pes. Pectoral and subcaudal glands are present. Dental formula is I 3 / 3, C 1 / 1, P 4 / 4, M 2 / 2 (x 2) = 40. Size of second upper incisor is subequal to adjacent upper incisors. Canine sizes are subequal to adjacent teeth. Several bilateral pairs of palatal foramina are present. Postorbital processes are absent.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.

038C87A8FFADAC03FFDC7C29FA603662.taxon	description	Descriptive notes. Head-body 102 - 199 mm, tail 111 - 163 mm, ear 22 - 39 mm, hindfoot 30 - 54 mm; weight 47 - 70 g. In some regions of the distribution, female Rufous Sengis can be slightly larger than males, but there generally is not substantial sexual dimorphism in body size. Tail is relatively long at c. 105 % of head-body length and dark brown with sparse hair; it lacks terminal tuft. Pinnae are broad, upright, and nearly hairless. Snout is long, thin, and flexible. Color of dorsum varies by region and includes rufous, gray, buff, and yellow tones; these variations might be associated with colors of habitat substrates. Tips of dorsal hairs are dark gray or gray-buff. Behind each ear, patch of buff hair extends onto nape of neck. Venter is pure white, and pectoral gland is fringed with distinguishable short white hairs. In adults, manus and pes are white (brown in juveniles). Rhinarium is hairy below. Prominent white eye-ring is present, with post-ocular patch of brown-black hair that intrudes on eye-ring and extends posteriorly. White ‘ brow’ branching from eye-ring sweeps superiorly adjacent to post-ocular patch and extends to near base of ear. Hairy inferior rhinarium and spectacled pelage pattern around eyes are traits shared only with the Somali Sengi (E. revoilii). Females have two anterior, two intermediate, and two posterior nipples; males have no nipples. Five digits are present on each manus and pes. Pectoral gland is present, and subcaudal gland is present but only slightly developed. Dental formulais 13 / 3, C 1 / 1, P 4 / 4, M 2 / 2 (x 2) = 40. Size of second upper incisor is distinctly smaller than both adjacent upper incisors. Canine sizes are subequal to adjacent teeth. Several bilateral pairs of palatal foramina are present.

038C87A8FFADAC03FFDC7C29FA603662.taxon	food_feeding	Food and Feeding. Arthropods, mostly insects, are the principal diet of the Rufous Sengi. During wet seasons, small proportions of fruits and green plant matter are eaten. In south-eastern Kenya, an analysis of stomach contents found (in decreasing frequency) harvester termites, black ants, beetles, crickets, grasshoppers, spiders, and silverfish. Feeding is selective; in some areas, termites and ants are only c. 40 % of available invertebrate prey but c. 75 % of the diet.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.

038C87A8FFADAC03FFDC7C29FA603662.taxon	breeding	Breeding. The Rufous Sengi is monogamous, and pairs mate for life. Reproduction occurs year-round, but births are more frequent during wet seasons. Smaller females (under 40 g) might carry only one embryo; larger females can carry up to two. Litters have 1 - 2 young. Gestation is ¢. 57 days, and interbirth intervals are 57 - 65 days. Females can enter estrus almost immediately postpartum. Birth weight is c. 10 g, and for the first 50 days daily gain is c. 0 - 75 g. Young are highly precocial at birth, with open eyes and ability to run within a few hours. Mothers visit young perhaps only once per day to nurse young. There is no direct paternal care of young. Juveniles are weaned at ¢. 30 days, after which parents aggressively chase them away from their territory. No species of soft-furred sengis use nests to shelter or for rearing their young.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.

038C87A8FFADAC03FFDC7C29FA603662.taxon	biology_ecology	Movements, Home range and Social organization. Home ranges of monogamous pairs overlap, but combined area has limited overlap with home ranges of neighboring pairs. If a male disappears, a neighboring male might engage in temporary polygyny during the vacancy. Home ranges are reported to be 0 - 2 - 0 - 5 ha. Individuals of a pair interact infrequently except during estrus. Both sexes aggressively defend their territory; males chase away males, and females chase away females. Monogamous mating system is probably a mate-guarding strategy. Trail systems are actively maintained by pushing aside debris with forelimbs and head.	en	Russell A. Mittermeier, Don E.

038C87A8FFACAC02FF1B7A86F86637C5.taxon	breeding	Breeding. The Short-snouted Sengi is monogamous, and pairs mate for life. In Zimbabwe, births occur year-round, but reproduction can be seasonal in other areas. Litter frequencies can be reduced in cooler months when insects are less abundant. Interbirth interval is ¢. 60 days in warmer months and ¢. 90 days in cooler months. Females can produce up to 23 ova per ovary per cycle, but limited uterus implantation sites constrain litter size. Embryo counts indicate that litters have 1 - 2 young. At parturition, newborns are highly precocial, with open eyes and almost immediate ability to run. Direct paternal investment is absent from all species of sengis that have been studied. No species of soft-furred sengis use nests to shelter or for rearing their young.	en	Russell A.

Distinguishing characteristics include longer tail (Western Rock Sengi c. 115 % of head-body length vs. Bushveld Sengi ¢. 105 %), darker dorsal tail (Western Rock Sengi near-black vs. Bushveld Sengi speckled gray), and presence of terminal tail tuft (absent in Bushveld Sengi). Pinnae are broad and upright, and snoutis long, thin, and flexible. Dorsum is gray-brown or rufous-brown. Some hairs, particularly along mid-dorsal axis, are longer and have black tips. Pelage of dorsal head and face is similar in color to dorsal body. Lateral fur is gray, and venter is gray-white to off-white. Behind each ear, distinctive patch of rufous-buff-yellow hair extends onto nape of neck. Long pale hairs grow along anterior margin of each pinna.

There is no evidence of sexual dimorphism in body size. Tail of the Eastern Rock Sengi is relatively long at ¢. 110 % of head-body length, pinnae are broad and upright, and snout is long, thin, and flexible. Dorsum is buff-gray, with dark gray hair tips. Lateral pelage is paler, and fewer hairs have dark gray tips. Colors of dorsal head and face are similar to dorsal body. White eye-ring is present, without intruding post-ocular patch. Venter is off-white or pale gray. Behind each ear, patch of buff hair extends onto nape of neck; it can be more conspicuous on individuals from northern parts of the distribution. Long pale hairs grow along anterior margin of each pinna, but otherwise pinnae are nearly hairless. Sparse hair covers tail, darker above than below. There is no tail tuft. Skin of plantar pes is black. Females have two anterior, two intermediate, and two posterior nipples; males have no nipples. Five digits are present on each manus and pes. Pectoral gland is absent, and subcaudal gland is present. Dental formula is I 3 / 3, C 1 / 1, P 4 / 4, M 2 / 2 (x 2) = 40. Canine sizes are subequal to adjacent teeth. Several bilateral pairs of palatal foramina are present. Postorbital processes are absent. Karyotype is 2 n = 30.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.

038C87A8FFA3AC0CFAC47AE9FDF1373B.taxon	food_feeding	Food and Feeding. Insects, mainly ants and termites, are the principal diet of the Eastern Rock Sengi. Other small invertebrates and limited plant material are eaten. Foraging occurs from covered areas, with rapid emergence to seize prey. Larger insects (e. g. grasshoppers) are carried back to cover for ingestion; this is probably a risk sensitive behavior.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.

038C87A8FFA3AC0CFAC47AE9FDF1373B.taxon	breeding	Breeding. The Eastern Rock Sengi is monogamous, and pairs mate forlife. In South Africa, births occur in September — March, corresponding with the warm, wet season. Male sperm are viable year-round, buttestes size and sperm count drop significantly when reproduction pauses during the cool season. Females can produce up to 89 ova per ovary per cycle, but limited uterus implantation sites constrain litter size. In Botswana and South Africa, litters have 1 - 2 young. Young are born with open eyes, fully furred, and highly precocial. Mothersvisit young infrequently for nursing, and there is no direct paternal care. Young females become sexually mature at 35 - 42 days. No species of soft-furred sengis use nests to shelter or for rearing their young.	en	Russell A. Mittermeier, Don E.

At the Weenen Game Reserve, South Africa, individuals are active at all hours (polycyclic) but are most active and furthest from their home range center for periods of about five hours beginning at dusk and at dawn. Periods of least activity are overnight and during the afternoon.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.

038C87A8FFA3AC0CFAC47AE9FDF1373B.taxon	biology_ecology	Movements, Home range and Social organization. Home ranges of monogamous pairs overlap, but combined area has limited overlap with home ranges of neighboring pairs. Males and females of a pair infrequently interact except during estrus. If a male disappears, a neighboring male might engage in temporary polygyny during the vacancy. One study found that average home ranges were ¢. 0 - 3 ha for males and c. 0 - 2 ha for females, and maximum home range of males was c. 1 - 3 ha. Monogamous mating system is probably a mate-guarding strategy. Limited home range overlap with neighboring pairs might indicate territoriality or at least mutual avoidance.	en	Russell A.

038C87A8FFA2AC0CFF117C82F59836D1.taxon	food_feeding	Food and Feeding. Insects, mainly ants, are the principal diet of the Cape Rock Sengi. Other arthropod prey includes termites, beetles, roaches, and locusts. Small amounts of green plant material can also be eaten. Some observations have found that the Cape Rock Sengi acts as a pollination vector while foraging on insects near flowers (Protea, Proteaceae) and drinking nectar of bulbous perennials (Whiteheadia, Asparagaceae). Main foraging strategy has been described as “ wait, dash, and snatch, ” which is consistent with observations of many species of sengis. The Cape Rock Sengi has been observed turning over hyrax (Procavidae) dung piles to pursue underlying insects.	en	Russell A. Mittermeier, Don E. Wilson (2018): Macroscelididae.
