Outline Activities
I'm working on taxonomy, phylogeny, biogeography and biodiversity of ants in the tropical Asia; using traditional morphological analysis, molecular phylogenetic analysis, divergence time estimation, haplotype network analysis, DNA barcoding, and ordination; aims to reveal phylogeographic history, ant diversity in Asia, effects of disturbance (deforestation, plantation, fire, flood, global warming) on ant assemblages.

1. Hosoishi, S., Maruyama, M., Yamane, Sk., Jaitrong, W., Hashim, R., Syaukani, S., Itioka, T., Sokh, H., Meleng, P. and Pham, T.H., Multilocus phylogeny and historical biogeography of the Crematogaster inflata-group (Hymenoptera: Formicidae) in Southeast Asia., Zoological Journal of the Linnean Society, 2023.07, A recent molecular phylogeny of the genus Crematogaster reclassified some members of the former subgenera Paracrema
and Physocrema into the C. inflata-group, now comprised of five species: C. ampullaris, C. inflata, C. modiglianii, C. onusta
and C. subcircularis. Here, a molecular analysis of the Crematogaster inflata-group and eight other species of the former
subgenus Physocrema (C. aurita, C. difformis, C. mucronata, C. physothorax, C. sewardi, C. tanakai, C. vacca and C.
yamanei) is conducted using a total of c. 4 kb of sequence data from six nuclear protein-coding genes and two mitochondrial
genes. Monophyly of the C. inflata-group is strongly supported. A revised morphological delineation of the subgroups is
proposed, supported by the molecular phylogeny: three morphologically distinct subgroups, the C. difformis-subgroup,
the C. vacca-subgroup and the C. inflata-subgroup. Molecular dating and biogeographical analyses indicate that the C.
inflata-group originated in the Sundaic region around the Middle Miocene 12 Mya and diversified from the Late Miocene
to Pliocene. Ancestral state reconstructions indicate that the C. inflata-group diversified from an ancestor with a swollen
propodeum and circular-shaped metapleural gland opening. Biogeographical reconstruction indicates that dispersal to
peripheral areas and allopatry due to sea-level changes shaped the evolutionary history of the C. inflata-group..

Hosoishi S, Yamane Sk, Sokh H, Discovery of a new phragmotic species of the ant genus Carebara Westwood, 1840 (Hymenoptera, Formicidae) from Cambodia, Journal of Hymenoptera Research, 2022.06, Several phragmotic species in the ant genus Carebara Westwood, 1840 with a cephalic shield are known from the Old World, but species with an anteriorly truncated head seem to be unknown until now. A new species, resembling the phragmotic workers of the ant genus Colobopsis, is here described as Carebara colobopsis Hosoishi & Yamane, sp. nov., based on major and minor worker found in Cambodia. This new species is similar to Carebara acutispina (Xu) and C. obtusidenta (Xu) in some important characters, but distinguished from the latter two by distinct metanotum and deep groove in front of metanotal disc in the major worker, and longer head and deep metanotal groove in the minor worker. This is the first confirmed record of a truncated phragmotic head in the major worker of the genus Carebara. We propose the Carebara acutispina species group to include all the three species, present a diagnosis of this group, and provide a key to species based on the major and minor worker castes..

Shingo Hosoishi, Kazuo Ogata, Cryptic diversity in the widespread Asian ant Crematogaster rothneyi (Hymenoptera: Formicidae) inferred from morphological and genetic evidence, Zoological Studies, 2019.06, The myrmicine species Crematogaster rothneyi is one of the most widely distributed ants in Asia, but it
has rarely been collected in the field. Its distribution range covers South and Southeast Asia, extending
approximately 5,000 km from India in the west to Sulawesi in the east. Despite this wide distribution
range, C. rothneyi has been treated as a single taxonomic species, and no combined morphological or
molecular analysis has been conducted to assess whether any intraspecific variation exists. The sequence
divergences of C. rothneyi populations, mainly obtained from Southeast Asia, were investigated by
analyzing 387 bp and 175 bp sequences of the 12S ribosomal RNA and cytochrome c oxidase subunit
(COI) genes, respectively. Phylogenetic analysis indicated that the C. rothneyi populations were separated
into three groups: group I from Thailand and Cambodia, group II from Bangladesh and Myanmar, and
group III from Krakatau and Sulawesi. Groups II and III were recovered as a single clade, sister to group
I. The interspecific divergences were 7.3% to 8.5% for 12S and 14.5% to 23.3% for COI between most C.
rothneyi specimens and Cambodian specimens, while divergence for 12S was 3.5% between Thai and
Cambodian specimens. The Thai specimens are not morphologically differentiated, and are considered
conspecific to C. rothneyi. We describe the Cambodian series as a new species, Crematogaster yaharai
sp. nov., based on unique antennal morphology and mesosomal sculpture patterns with molecular
evidence. Crematogaster rothneyi civa Forel, 1902 is synonymized under C. rothneyi. Crematogaster
rothneyi is widespread and has sister species, suggesting recent diversification within the Indochinese
