Four new species of terrestrial earthworms from the zebrus-group in the genus Amynthas Kinberg, 1867, are described from Nan province, north Thailand: Amynthas phatubensis sp. n., from Tham Pha Tub Arboretum, Amynthas tontong sp. n., from Tontong Waterfall, Amynthas borealis sp. n., from Chaloemprakiat district, and Amynthas srinan sp. n., from Srinan National Park.After comparing with the two closely related Laos species Amynthas chandyi Hong, 2008 and Amynthas namphouinensis Hong, 2008, the four new species show clear morphological differences, and also it is confirmed that there are no previous records of the species described here. Amynthas phatubensis sp. n. is the largest (longest) sized of these earthworms and is the only species that lives in limestone habitats. The genital characters are different among them and also from the two Laotian species. Molecular systematics would be a good method for further analysis of the diversity and species boundaries in SE Asian Amynthas.

Since none of the four species described in this paper seems to fit the descriptions of species described in the past, the purpose of this paper is to formally describe these species as new to science. Their descriptions follow.
Material and methodsEarthworms were collected from deciduous forests in many areas in Nan province, north of Thailand, by carefully digging up the topsoil near casts and by hand sorting the leaf litter. The worms were killed in 30% (v/v) ethanol, photographed, transferred to 5% (w/v) formalin for fixation for approximately 12 hours, and then transferred to 70% (v/v) ethanol for longer term preservation and subsequent morphological studies.
Duplicate specimens and/or tissue samples (in the cases
of morphotypes determined to be unique on field inspection) were
preserved in 95% ethanol for molecular data and DNA barcoding. Tissues
were sent to the Canadian Center for DNA Barcoding (
The descriptions of each species were made during observation under a Stemi DV 4 ZEISS stereoscopic light microscope. Drawings were made of the body segments and the distinct external characters and internal organs, as mentioned above, and are shown in Figures 2–5 for the four new species, respectively. The number of segments and the body width and length were measured in both full adults and juveniles, and are presented as the range (min-max) and mean±one standard deviation.
Type specimens housed at the Department of Biology, Faculty of Science, National University of Laos, Vientiane, Laos (BDNUL), of the two closely related Laos species, Amynthas chandyi Hong, 2008 and Amynthas namphouinensis Hong, 2008, have been critically studied and compared with the new species of this report.
Holotype and paratype specimens have been deposited in the Chulalongkorn University, Museum of Zoology, Bangkok, Thailand (CUMZ). Additional paratypes are housed in the Biozentrum Grindel und Zoologisches Museum, Hamburg, Germany (UHH), and the Natural History Museum, London (NHM).

The holotype measures 110 mm body length with 108 segments; the twenty one paratypes range in size from 80–148 mm (108±21.93 mm) body length with 85–114 segments (Table 2).
Tham Pha Tub Arboretum, Nan province, Thailand, 18°51'16.4"N, 100°44'10.1"E, 265 meters elevation (11th October 2009). We also collected another lot of further specimens from Tontong Waterfall, Nan province (location 3 in Figure 1), which is located about a hundred kilometers north of the type locality.
This species was named after the type locality, Tham Pha Tub Arboretum.
The holotype (CUMZ 3204) and 15 paratypes (CUMZ 3205) and 10 paratypes (CUMZ 3212) are deposited in Chulalongkorn University, Museum of Zoology. Another four paratypes will be deposited in the Biozentrum Grindel und Zoologisches Museum, Hamburg, Germany (UHH), and three paratypes in the Natural History Museum, London (NHM).
Found in the top soil at about 10 cm depth, the soil surface was covered with leaf litter in a deciduous limestone forest at Tham Pha Tub Arboretum. The soil was carefully dug close to the casts. Many ariophantid snails, Cryptozona siamensis Pfeiffer, 1856 were on the ground or under leaf litter.
Amynthas phatubensis sp. n. is a medium to large sized terrestrial earthworm with a pair of mp surrounded by six genital papillae on segment XVIII. Within the zebrus-group, this species is diagnosed by the unique combination of dorsal pores in 5/6, simple digitate caeca, ventrally joined testis sacs, genital marking glands in the spermathecal segments, and the spermathecal characters of the large ovate ampulla, stalked diverticulum whose folds are membrane-bound, and spherical knob terminal diverticulum sac.
Amynthas phatubensis sp. n. has very simple characteristics of the genus, but among these, only the superficial male pores are external. In most newly collected specimens it was difficult to observe the pores or marks on the bodies. However, after preservation they can be seen more clearly. The internal organs are much more easily discerned. This new species is quite distinct when compared to the two closely related species from Laos, Amynthas chandyi Hong, 2008 and Amynthas namphouinensis Hong, 2008, which belong in the same zebrus-group. The two Laos species are a little bit smaller than Amynthas phatubensis sp. n., especially Amynthas chandyi. Even though Amynthas namphouinensis is much closer in appearance to Amynthas phatubensis sp. n., there are distinct differences between the type specimens (Figs 6 and 7). For example, the distance between the mp of Amynthas phatubensis sp. n. is 4.2 mm for the holotype and range from 3.0–4.5 mm (4.27±0.57mm), while for Amynthas namphouinensis this was significantly smaller, ranging from 1.4–1.5 mm. The distance between a pair of sp is also different, being 3.5–4.5 mm (4.12±0.4 mm) for Amynthas phatubensis sp. n. and 1.4–2.0 mm in Amynthas namphouinensis. The distance between the male pores as a fraction of the estimated circumference of the 18th segment is 0.30–0.33 in Amynthas phatubensis sp. n., but 0.10–0.14 circumference apart in Amynthas namphouinensis. Moreover, Amynthas phatubensis sp. n. has no genital marking glands on segments XVII–XIX, where Amynthas namphouinensis has sessile genital marking glands, but contains two distinct genital marking glands located close to sc that are absent in Amynthas namphouinensis.
Two populations of Amynthas phatubensis
sp. n. were sampled, one from the type locality and one from Tontong
waterfall. Distinct DNA barcode clusters corresponding to these
populations had intra-cluster Kimura 2 parameter distances of 0.023
(N=9) and 0.016 (N=5) respectively. The inter-cluster divergence between
the two populations is 0.084. Based on the morphological unity and the
fact that the divergence is less than that usually seen between
congeneric species pairs of earthworms (

Tontong Waterfall, Nan province, Thailand, 19°12'35.9"N, 101°04'13.7"E, 1, 128 meters elevation (10th October 2009).
This species was named after the type locality, Tontong Waterfall.
The holotype (CUMZ 3206) and two paratypes (CUMZ 3207) are deposited in Chulalongkorn University, Museum of Zoology. Another paratype will be deposited in the Biozentrum Grindel und Zoologisches Museum, Hamburg, Germany (UHH).
Found in the top soil at about 10 cm depth, the soil surface covered with leaf litter of deciduous forest which originated at the Tontong Waterfall area. The soil was carefully dug close to surface casts. Most surrounding areas have been modified to agricultural fields.
Amynthas tontong sp. n. is a small sized terrestrial earthworm with a close indistinct pair of male pores with a pair of genital markings in intersegment 18/19. Spermathecae consists of a thumb shaped ampulla and a spherical terminal knob shaped diverticulum. Genital marking glands absent, first dorsal pore in 5/6, intestinal caeca simple, intestinal origin XV, septa 8/9/10 absent, testis sacs joined ventrally.
Amynthas tontong sp. n., along with Amynthas srinan sp. n. and Amynthas exiguus exiguus, is one of the smallest sized Amynthas ever recorded in Thailand. The basic external characters are easily seen in both newly collected and preserved materials. Compared with the two other closely related species from Laos, Amynthas chandyi Hong, 2008 and Amynthas namphouinensis Hong, 2008, which belong in the same zebrus-group, Amynthas chandyi is similar to Amynthas tontong sp. n. However, it differs in the specific details of the significant characters, such as the distance between the mp in Amynthas tontong sp. n. is 1.0 mm for the holotype and ranged from 1.0–1.2 mm (0.93±0.12 mm), while in Amynthas chandyi it ranged from 1.5–2.4 mm. The distance between the male pores as a fraction of the estimated circumference of the 18th segment is 0.15–0.19 in Amynthas tontong sp. n., but 0.14–0.32 in Amynthas chandyi. The arrangement of the genital markings of both species are totally different, and the distance between a pair of sp is also different, being 0.8–1.0 mm (1.1±0.1 mm) in Amynthas tontong sp. n. and 1.2–1.5 mm for Amynthas chandyi. Moreover, Amynthas tontong sp. n. has no genital markings near to the sp, whilst Amynthas chandyi exhibits circular genital markings in various locations, paired or single mid ventral in VII, VIII; usually 3 or 4 in total.
Alcohol-preserved paratype specimens of Amynthas tontong sp. n. belonged to a single DNA barcode cluster, with an intra-cluster divergence of 0.005 (N=3), and diverging from Amynthas phatubensis sp. n. by 0.294, and by 0.189 for an undescribed species. An undescribed morph at Tham Pha Tub diverged by 0.100, and may represent a subspecies. A consensus sequence is in Appendix 1.

One pair of sc in VIII, each spermathecae consists of a large sac-shaped ampulla and elongated tubular shaped diverticulum. Testis sacs joined ventrally, intestinal origin XV, intestinal caeca simple, first dorsal pore in 5/6.
Amynthas borealis sp. n. is one of the smaller Amynthas. The characteristic male field is difficult to see in newly collected specimens but can be clearly observed after preservation. Compared with the two other closely related species from Laos, Amynthas chandyi and Amynthas namphouinensis, which belong in the same zebrus-group, Amynthas chandyi is similar to Amynthas borealis sp. n. However, distinctive differences include the distance between mp of the new species, being 1.0 mm in the holotype with a range of 0.8–1.0 mm (0.95±0.09 mm) in Amynthas borealis sp. n. compared to 1.5–2.4 mm. The distance between the male pores as a fraction of the estimated circumference of the 18th segment is 0.10–0.14 in Amynthas borealis sp. n., but 0.14–0.32 in Amynthas chandyi. There are no genital markings in the new species; the distance between a pair of sp is also different, being 0.5–1.0 mm (0.9±0.19 mm) in the new species compared to 1.2–1.5 mm for Amynthas chandyi. Moreover, Amynthas borealis sp. n. has no genital marking glands at all, whilst Amynthas chandyi exhibits circular genital markings in various locations, paired or single mid ventral in VII and VIII; usually 3 or 4 in total.

The holotype measures 47 mm body length with 77 segments and the first dorsal pore located at 5/6; the twenty eight paratypes range in size between 35–47 mm (39.75±4.27 mm) body length with 52–78 segments, and first dorsal pore at 4/5 (8 samples) or 5/6 (20 samples) (Table 5).
Srinan National Park, Nan province, Thailand, 18°22'11.1"N, 100°50'23.2"E, 607 meters elevation (30th September 2010).
This species was named after the type locality Srinan National Park.
The holotype (CUMZ 3210) and 25 paratypes (CUMZ 3211) are deposited in Chulalongkorn University, Museum of Zoology. Another five paratypes will be deposited in the Biozentrum Grindel und Zoologisches Museum, Hamburg, Germany (UHH), and four paratypes in the Natural History Museum, London (NHM).
Found in the top soil at about 10 cm depth, the soil surface covered with leaf litters of deciduous forest. The soil was carefully dug close to the castes.
Amynthas srinan sp. n. is the smallest Amynthas ever collected in Thailand. Male pores on distinct round porophores, genital markings paired near mid ventral of VII, VIII, XVII and XVIII; each with genital marking glands. Each spermathecae consists of a kidney-shaped ampulla and an oval shaped diverticulum. Testes sacs ventrally joined, intestinal origin XV, intestinal caeca simple, first dorsal pores at 4/5 or 5/6.
Amynthas srinan sp. n., along with Amynthas exiguus exiguus and Amynthas tontong sp. n., is one of if not the smallest Amynthas recorded so far. It has external characteristics which are easily seen in both newly collected and preserved materials. Compared with the two other closely related species from Laos, Amynthas chandyi and Amynthas namphouinensis, which belong in the same zebrus-group, Amynthas chandyi is very similar in appearance to Amynthas srinan sp. n. However, they clearly differ in certain specific details of their significant characters, such as the distance between the mp which in Amynthas srinan sp. n. is 1.5 mm for holotype and ranged from 1.5–2.0 mm (1.41±4.27 mm), while in Amynthas chandyi this ranged from 1.5–2.4 mm. The distance between the male pores as a fraction of the estimated circumference of the 18th segment is 0.24–0.30 in Amynthas srinan sp. n., and 0.14–0.32 in Amynthas chandyi. This is not convincing as a diagnostic difference, because there is significant overlap with the highly variable Amynthas chandyi. In addition, although genital markings are clearly observed in both Amynthas chandyi and Amynthas srinan sp. n. on the sc and mp areas, Amynthas srinan sp. n. has a much larger number and different arrangement of such markings. The distance between pairs of sp is quite similar, being 1.5–2.0 mm (1.34±2.31mm) in Amynthas srinan sp. n. and 1.2–1.5 mm in Amynthas chandyi.
The genus Amynthas
is widely distributed in the Asian continent, where it is one of the
dominant genera. In Thailand it occurs in various types of lowland
forest habitats, dry evergreen, moist evergreen, deciduous and
limestone forests, encompassing diverse soil pH values, from acidic to
alkali soils (
The four new species range in size, with respect to other Amynthas members, from moderate to very small, of which Amynthas phatubensis sp. n. is the longest. The other three species are almost the same size and close to the two Laotian species, as shown in Table 6.
However, the spermathecae (sc) and genital marking locations of the
four new species are clearly different from the two closely related Laos
species. The four new Amynthas species described here belong to the zebrus-group, as defined by
Morphological characteristics for between these four new species and two know species from Laos

Amynthas phatubensis sp. n. is the only species that lives in limestone habitats in leaf litter and also in shallow mild alkali topsoil. The soil humidity can be quite low and is of a clay loam structure. The other three species are smaller in size and were found in almost harder, muddy sandy clay substrates. Amynthas tontong sp. n. lives in deeper soil of a high humidity around waterfalls. Amynthas borealis sp. n. and Amynthas srinan sp. n. are found in deciduous forests, which have mostly been modified as agricultural fields. The soil is drier and harder. The genital marking glands of Amynthas phatubensis sp. n. and Amynthas srinan sp. n. are distinct from other two species (Table 6 and Figs 2–5), whilst Amynthas tontong sp. n. show two postclitellar genital markings that are absent in Amynthas borealis (Figs 3 and 4) The diagnostic differences are shown in the dichotomous key to the sixteen Thai and two Laotian Amynthas species, below.
The zebrus-group is composed of eleven nominal species: Metaphire hilgendorfi (Michaelsen, 1892), Amynthas palmosus (Chen, 1946), Amynthas magnipapillatus (Qui and Wang, 1992), Amynthas zebrus (Benham, 1896), Amynthas culminus Michaelsen, 1899, Amynthas principalis (Michaelsen, 1932), Amynthas xuongmontis (Thai & Samphon, 1990), Amynthas fasciculus (Qui, Wang & Wang, 1993), Amynthas heaneyi James, 2004, Amynthas namphouinensis Hong, 2008 and Amynthas chandyi Hong, 2008. Within the zebrus-group, the first three species show manicate intestinal caeca, while the current newly described four species have simple finger-shaped intestinal caeca. The three latter nominal species are longer in body length (200–300 mm) compared with the size of these four new species which ranged from 35–148 mm. Amynthas heaneyi can be distinguished by its proandric character (James, 2004), while the four new described species are holandric. Amynthas fasciculus has coiled and kinked spermathecae, whereas Amynthas phatubensis sp. n. has large ovate ampulla, Amynthas tontong sp. n. has thumb shaped ampulla, Amynthas borealis sp. n. has sac-shape ampulla, and Amynthas srinan sp. n. has oval to kidney-shaped ampulla. Amynthas xuongmontis clearly differs from these four new species in the genital marking located on XVIII, whereas located on VII, VIII, XVII, XVIII in Amynthas phatubensis sp. n., located between 18/19 in Amynthas tontong sp. n., absent in Amynthas borealis sp. n. and located on VII, VIII, XVII, XVIII in Amynthas srinan sp. n.
