The flea genus Araeopsylla Jordan and Rothschild, 1921 contains nine species distributed throughout the Palaearctic, Ethiopian and Oriental Regions primarily on mollosid bats. A new species of bat flea, Araeopsylla goodmani, is described. This new species is represented by three females collected from one male specimen of the mollosid bat Chaerephon jobimena Goodman & Cardiff, 2004 from Fianarantsoa Province, Madagascar. A second new species, Araeopsylla smiti, is described from one male from the Rift Valley, Kenya. It was collected from the molossid bat Chaerephon bivittatus (Heuglin, 1861). This represents the first record of Araeopsylla in Kenya. Previous records of Araeopsylla in the Malagasy region included Araeopsylla martialis (Rothschild, 1903) from Reunion Island and Madagascar. One hundred fifty-eight specimens (64♂, 94♀) of A. martialis were collected from 67 specimens (flea intensity of 2.4 fleas per host) of Mormopterus jugularis (Peters, 1865) across three provinces of Madagascar (Fianarantosa, Toamasina, and Toliara). Mormopterus jugularis is clearly a common host for A. martialis. Dampfia grahami grahami (Waterston, 1915) is also reported from Eptesicus matroka (Thomas & Schwann, 1905) which is the first record from this host species and the first time the genus Dampfia has been documented in Madagascar. Although Lagaropsylla consularis Smit, 1957 and Lagaropsylla idae Smit, 1957 have been reported in Madagascar previously, Mops leucostigma Allen, 1918 is a new host record for L. idae. The flea intensity of L. idae (64♂, 83♀) on 28 specimens of M. leucostigma was extremely high at 5.3 fleas per host. A key to the genus Araeopsylla is provided.

There are currently nine species represented in the flea genus Araeopsylla Jordan & Rothschild, 1921 (Lewis 2006) The distribution of Araeopsylla is wide-spread, extending across Africa, Madagascar, southern Europe, the Middle East, and Southeast Asia. Members of the genus primarily parasitize bats of the families Emballonuridae and Molossidae. Beaucournu and Fain (1983) and Beaucournu (2004) provided geographical and host lists for Ischnopsyllidae of continental Africa, while Beaucournu and Fontenille (1993) catalogued the fleas of Madagascar. Other papers include specific accounts of miscellaneous small collections of Araeopsylla. Although the genus has a broad geographical distribution, specimens are not commonly collected.

During the early 1970’s, the author was associated with a project conducted by the late Hank W. Setzer, Department of Mammalogy, National Museum of Natural History that included the collection of small mammals and their ectoparasites across most of the African countries. The fleas collected were made available to the author and were studied for several years. During those early flea studies, the author recognized a new species of Araeopsylla and has maintained the single male specimen for 40+ years in anticipation that the female might be discovered. To date, no additional specimens of this species have been discovered.

The Field Museum of Natural History, Chicago, IL conducted mammal studies in Madagascar and also collected ectoparasites from those mammals. The fleas were provided to the author and they were subsequently identified and returned to the Field Museum. Among the material examined were three female specimens representing a new species of Araeopsylla and several new country and host records. These two new Araeopsylla taxa from Kenya and Madagascar will be described herein. Additional records of bat fleas from Ghana, Kenya, and Madagascar will also be documented and discussed.


Details of the genitalia of the whole mounted specimen of A. smiti (described below) were difficult to visualize. Therefore the specimen was photographed, dissolved off the microscope slide with xylene, dissected, and remounted in Canada balsam. Images were prepared using an Olympus BX61 Compound Microscope, Olympus CC12 digital camera accompanied with an Olympus Microsuite™ B3SV program. This system was also used to measure fleas in accordance with anatomical markers annotated in Hastriter and Eckerlin (2003). References to “flea intensity” implies the mean number of fleas from hosts that were positive for respective flea species. The primary types of A. goodmani and A. smiti were deposited in the Field Museum of Natural History(FMNH), Chicago, IL and the National Museum of Natural History, Washington, D.C., respectively. One paratype of A. goodmani (SMG-13344-2) was deposited in the FMNH collection and one paratype (SMG-13344-3) in the Brigham Young University flea collection (BYUC).

Madagascar records of bat fleas were extracted from data bases of the FMNH flea collections for which the author provided original species identifications. The additional species annotated herein were all retained in the FMNH flea collection (some mounted on microscope slides and others preserved in alcohol) with exception of those retained in the BYUC noted under “Material Examined” sections. For brevity, collectors are listed as: A. Kofi (AK), B.J. Hayward (BJH), C.B. Robbins (CBR), Fanja H. Ratrimomanarivo (FHR) and (RHF), Steve M. Goodman (SMG).

The new species epithet goodmani is named in honor of its collector, Dr. Steven M. Goodman, Field Museum of Natural History, Chicago, IL for his untiring efforts and excellent contributions to the field of mammalogy, specifically for his work on bats and small mammals in Madagascar from which these specimens were obtained.


Although the respective male and female sexes of the two new flea species described in this paper were both collected from the bat genus Chaerephon representing two species [Chaerephon bivittatus (Heuglin, 1861) from Kenya and Chaerephon jobimena Goodman and Cardiff, 2004 from Madagascar], they do not represent the same species of flea. Chaerephon bivittatus and C. jobimena are allopatric in their distributions. Although there exists some sexual dimorphism among fleas, these females differ drastically from the male described below as A. smiti. Characteristics examined included major differences in the nature of the genal teeth, pre-oral tuber, pronotal comb, shape of the gena, variations in chaetotaxy of head and abdomen, and abdominal incrassations.

Araeopsylla lumareti Smit, 1958 (known only from the male sex) could potentially represent the male of this new species for which only females are known; however, this is doubtful based on their differences in hosts, morphology, and geographical remoteness. Araeopsylla lumareti is known only from the type locality in Cambodia from “bat guano” opposed to the occurrence of A. goodmani in Madagascar from C. jobimena, which is endemic to Madagascar. The frontal row of setae of males of A. lumareti are comprised of “small setae” and the occiput is “without marked dorsal incrassations” (Smit 1958). The frontal row setation of A. goodmani range from small setae to spiniform setae, the occiput is with marked dorsal incrassations, and the first genal tooth is much broader than that of A. lumareti. Based on these observations, I am confident that the male of A. lumareti does not represent the male counter-part of A. goodmani. Additional collecting of fleas from L. jobimena in Madagascar and from the temple of Angkor-Vat in Cambodia is needed to discover the males of A. goodmani and the females of A. lumareti.

Several species of the bat genus Chaerephon have yielded several bat flea species of the genus Lagaropsylla (Beaucournu 2004, Beaucournu and Fain 1983, Beaucournu and Fontenille 1993, Beaucournu and Kock 1994a, and Klein and Uilenberg 1966), but this is the first record of Araeopsylla collected from the bat genus Chaerephon throughout Madagascar or tropical Africa.

Type material examined

Madagascar, Fianarantsoa Province: Isalo, 3.8 km NW Ranohira, along Namaza River (22°32'24"S, 45°22'48"E), Chaerephon jobimena ♂, 1 XII 2002, SMG, (SGM-13344-1, holotype ♀, SGM-13344-2, paratype ♀, FMNH) (SGM-13344-3, paratype ♀, BYUC).

Araeopsylla smiti Hastriter, sp. n.

Figs 8–13


Distinguished from all other species of Araeopsylla by the details of the telomere and distal arm of S-IX. The telomere is acutely pointed at apex and has a broadly rounded lobe along its ventral margin (Fig. 10). The ventral lobe at the base of the distal arm of S-IX that is present in other Araeopsylla species is short, pencil-like and without an expanded lobe at its apex. The ventral lobe of the new species is drastically longer and adorned with an ornate apical lobe (Fig. 11). The eighth sternum, unlike all other species, has a lobe (paired) with tufts of long, coarse setae (Fig. 11).

Head. Margin of frons gradually thickened from falx to oral angle. Frontal row of 9–10 minute setae. Area between frons and frontal row of setae with small punctate structures and two placoid pits. Area between frons and frontal row not white or clear, but moderately sclerotized. One placoid pit postad to frontal row of setae near base of genal tooth. Seven to eight minute setae postad to frontal row; group of 6–7 variable sized setae near ventral margin of antennal fossa. Eye fused into darkly sclerotized genal lobe. Genal lobe tapered and broadly rounded at apex; with minute apical tooth. Setae in occipital area rather randomly arranged. Five setulae along dorsal margin of antennal fossa; each as long as other randomly arranged setae in occipital area. Two small setae postad to antennal fossa in position of what is usually 4-5 spiniform setae in other Araeopsylla species. Apex of scape enlarged; three long setae along upper margin and three marginal setae at apex. Pedicel with several fine setae along apical margin; none extending beyond first segment of antenna. Clavus asymmetrical; not extending beyond margin of head. Five segmented labial palpus extended to 1/3 length of fore coxa. Proximal segment of five segmented labial palpus rather bulbous in form (Fig. 8).

Thorax. Pronotum with 26 ctenidia; each acutely pointed and only slightly shorter than length of pronotum. Setae on pronotum randomly arranged. Two dorsal and two ventral pseudosetae under mesonotal collar. Metanotum with three rows of setae; two marginal short, stout spinelets at dorsal apex of sclerite. Pleural rod nearly centrally attached to sclerotic dome. Ventral portion of metasternum lobed downward between coxae. Pleural arch absent. Metepisternum with squamulum and one long seta at dorsal margin. Metepimeron with nine setae; spiracle large and round.

Legs. Fore coxa with ~40 lateral setae. Fore femur with 2 minute setae on mesal surface; none on lateral surface. Mesal surface of mesotibia with single row of five setae; multiple setae on lateral surface. Mesal surface of metatibia with single row of seven setae; multiple setae on lateral surface. Meso- and metatibiae with five well defined notches; two setae at each. Multiple single setae interspersed along margins between defined notches. Each tarsal segment longer than adjacent more distal segments on meso- and metatarsi. Five lateral plantar bristles on all distitarsomeres; first pair displaces between second pair. Two pre-apical plantar bristles on each distitarsomere (Figs 12–13).

Unmodified abdominal segments. Single spinelet on apex of T-I. Globular sclerotized incrassation at base of each terga (T-I–VII). Pigmented banding extends slightly ventrally from each incrassation. Each terga with single uninterrupted row of setae; one seta below level of each round spiracle. Single long antesensilial bristle. Ventral margin of each sternite is heavily sclerotized. Sternites II–III with one minute seta in row; S-IV–VI with two minute setae in each row.

Modified abdominal segments. Basimere without lobes or sinuses. Telomere with large lobe on lower ventral margin; a few fine setae along ventral margin of telomere above lobe. Tergum VIII encompassing basimere and telomere with all setae restricted to dorsal half of sclerite (Fig. 10). Sternum VIII with large lobe bearing tuft of long coarse setae. Crescent sclerite of aedeagus long, thin, and inverted so tectum is directed cephalad. Sclerotized inner tube straight, somewhat broad. Crochet with prominent truncate upper lobe and sharp ventral lobe. Distal arm of S-IX with sigmoid lobe similar to many bat species, but what is usually a small pencil-like lobe in other species, this lobe is greatly extended and expanded at its apex. The expansion bears two small setae at base of expansion, two setae on apico-dorsal surface, and one seta on ventral margin of expansion. A group of very fine hairs adorns the base of the ventral lobe of the distal arm of S-IX (Figs 9–11).


Mr. F.G.A.M. Smit, during his long tenure at the British Museum, London was without doubt, a major contributor to our knowledge of the global flea fauna. It is thus fitting to name this flea smiti in his honor as a noun in apposition.


This is the first record of the genus Araeopsylla occurring in Kenya, although the genus has been recorded throughout tropical Africa.

Araeopsylla martialis (Rothschild, 1903)

Ceratophyllus martialis Rothschild, 1903

Araeopsylla martialis Jordan & Rothschild, 1921: 146; Hopkins and Rothschild 1956: 323–325; Lumaret 1962: 12; Klein and Uilenberg 1966: 53; Beaucournu and Fain 1983: 458, 460, 465; Beaucournu and Fontenille 1993: 79; Lewis 2006: 44: Marcus 1961: 190.


Although Araeopsylla is generally collected only in very small numbers across its range, A. martialis is exceptional. Sixty-seven individual M. jugularis specimens yielded one or more specimens of A. martialis. These were collected in three provinces of Madagascar (Fianarantosa, Toamasina, and Toliara). A total of 158 (64♂, 94♀) specimens were harvested from the 67 specimens of M. jugularis, yielding a flea intensity of 2.4. One male specimen of A. martialis was collected from Rousettus madagascarensis. Other species of bats did not harbor A. martialis. Its occurrence on a Rousettus sp. is likely an accidental association.

A total of 15 specimens (8♂, 7♀) was collected from four specimens of the Malagasy endemic Neoromicia matroka (Thomas & Schwann, 1905). This flea is not commonly collected and the only known existing records include the holotype ♂ from Eptesicus capensis = Neoromicia capensis (A. Smith, 1829) from Cape Town, South Africa, 3♀ specimens from Natal, and 2♀ from Orange Free State, South Africa (bat host species undetermined). Neoromicia capensis is widely spread across sub-Saharan Africa. Although not found in Madagascar, Goodman et al. (2012) considered N. capensis to be the closest ally and sister group to N. matroka. The current specimens represent a new country and host record and substantially increase the known number of specimens available for study. The hosts for Dampfia are thus far restricted to the family Vespertilionidae.

Lagaropsylla consularis has been reported previously in Madagascar and is among the more common species in the genus, primarily parasitizing C. pumilus. Chaerephon pumilus has a broad range from Yemen to Senegal, south to South Africa and Madagascar. Neoromicia somalicus (Thomas, 1901) from which L. consularis was collected in Kenya, is also found in Madagascar. Reported primarily on molossid bats, L. consularis has also been documented on hipposiderid and vespertilionid bats (Beaucournu 2004 and Smit 1957).

Lagaropsylla hoogstraali has been documented in Angola, Rwanda, Sudan, Zaire and Madagascar. Although there are few collections of this flea, most have been collected from Mops midas (Sundevall, 1843), a broadly distributed bat in continental Africa and Madagascar. Ratrimomanarivo et al. (2007) concluded that the subspecific populations of M. midas in continental Africa and Madagascar were invalid. The flea L. hoogstraali occurring on M. midas in both regions would support the conclusions of Ratrimomanarivo et al. (2007).

Beaucournu (2004) suggested that Mops condylurus (A. Smith, 1833) is the principle host of L. idae. Specimens of L. idae in my collection from Ghana and Kenya were also collected from M. condylurus. This host is widely distributed across Africa but is not found in Madagascar. Mops leucostigma, endemic to Madagascar, is very closely allied to the mainland species M. condylurus. A total of 147 specimens (64♂, 83♀) to include those listed in the “Materials examined” section below and those preserved in alcohol in the FMNH was collected from 28 specimens of M. leucostigma, yielding a flea intensity of 5.3 fleas per host. An average of 5+ fleas per host is a very high flea intensity for any bat flea, as bat fleas in general, are usually found in extremely low numbers. Mops leucostigma is the preferred host of L. idae in Madagascar and it was not collected from any other bat species in Madagascar.
