Introduction
The genus Leptogenys Roger, 1861 includes 316 valid nominal species and 14 subspecies and is widespread
in tropical and subtropical regions, with some species distributed in Holartics (Lattke, 2011; Janicki et al., 2016;
Guénard et al., 2017; Arimoto & Yamane 2018). Previously in Sumatra Island, the sixth largest island of the
world, nine species and three subspecies have been recorded (Janicki et al., 2016; Guénard et al., 2017), but the
total species richness of the genus seems to be underestimated if compared with other localities of Indonesia or
other parts of Southeast Asia, such as 15 species in Java (Karavaiev, 1925, 1926; Chapman & Capco, 1951; Ito
et al., 2001), 14 species in Thailand (Jaitrong & Nabhitabhata, 2005; Khachonpisitsak et al., 2020), 18 species
in Borneo (Bakhtiar & Chiang, 2011; Pfeiffer et al., 2011), 17 species and two subspecies in West Malaysia and
Singapore (Imai et al., 1983; Maruyama et al., 2010; Arimoto, 2017; Wang et al., 2022). Then, in our course of
inventory and taxonomic studies of ants in Sumatra, we have newly recorded species and genera from Sumatra
(Satria et al., 2015; Satria et al., 2017; Satria & Yamane, 2019; Satria & Herwina, 2020; Satria & Jannatan, 2021;
Musfira et al., 2022; Satria et al., 2022), and we herein record Leptogenys borneensis Wheeler, 1919 as new to
Sumatra Island. Furthermore, we also describe the hitherto unknown male of this species for the first time, with
a special attention to genital morphology.
Material and Methods
In our surveys of leaf-litter ants conducted in December 2021 in Mount Sago (0°19'16.1472" S
100°39'39.2472" E, ca. 1500 m alt.), Situjuah Banda Dalam, Situjuah Limo Nagari, 50 Kota District, West Su-
matra, Indonesia, a colony (colony code: RS-SG-02) of Leptogenys borneensis was found by visual searching
and collected. All specimens were deposited in the Laboratory of Ecology, Department of Biology, Faculty of
Mathematics and Natural Sciences, Universitas Negeri Padang which is managed by Rijal Satria (RSC).
Species determination of Leptogenys borneensis was made by referring to the original description by
Wheeler (1919), and images of the type material (MCZ cotype no. 20498) provided by the Database of the Zoo-
logical Collections, Museum of Comparative Zoology, Harvard University (MCZbase, 2022).
The genitalia of the males preserved in 70 % ethanol were slide-mounted by following Satria et al. (2015).
The genitalia were dissected into several main components using forceps in a small amount of Euparal (Wal-
deck GmbH & Co. KG) on a slide glass, and covered with a cover-slip. These slide-mounted specimens were
examined with a Nikon SMZ1270 stereomicroscope.
Multi-focused montage image were produced using Helicon Focus Pro. (Helicon Soft Ltd., http://
www.heliconsoft.com/) from a series of source images taken by a Canon EOS KissX5 digital camera
attached to a Nikon SMZ1270 stereomicroscope. Artifacts/ghosts and unnecessary parts (unfocused ap-
pendages, insect pin, etc.) surrounding or covering target objects were erased and cleaned up using the
retouching function of Helicon Focus Pro, and the color balance, contrast and sharpness were adjusted
using Adobe Photoshop CS6.
The parts of the bodies were measured using ImageJ 1.49 m (National Institute of Mental Health, USA,
available at http://imageJ.nih.gov/ij/) based on the photographs taken using a Canon EOS KissX5 digital cam-
era attached to the Nikon SMZ1270 stereomicroscope under suitable magnifications. Morphological termi-
nology, abbreviations of measurements and indices follow Boudinot (2013, 2018), and Satria et al. (2015) for
genitalia, and Arimoto & Yamane (2018) for body: HW = head width; HL = head length; EL = eye length;
EW = eye width; OL = median ocellus length; OED = ocellus-eye distance; SL = scape length; WL = Weber's
length; PW = pronotum width; PTH = petiole height; PTL = petiole length; CI = HW×100/HL; SI = SL×100/
HW; PTHI = PTH×100/PTL.

Remarks
Leptogenys borneensis is recorded for the first time in Sumatra Island. The colony was
found in decayed wood stump along the hiking trails (ca. 1500 m a.s.l.). Workers and males
were found but no queen was found from the colony.
So far, based on Forel (1913), Karavaiev (1925, 1926) and this paper, the male caste
is known for the following four species and one subspecies of the genus Leptogenys from
the island of Sumatra: Leptogenys diminuta (F. Smith, 1857); Leptogenys diminuta fruh-
storferi Emery, 1896; Leptogenys kraepelini Forel, 1905; Leptogenys myops (Emery, 1887),
24 R. Satria, F. A. D. Nugraha, A. Achyar, D. Zulyetti, & K. Eguchi
including Leptogenys borneensis in the present study. However, the morphology of the
male genitalia of these species remains unknown, except for L. borneensis, which is pro-
vided in this study.
The morphology of male genitalia provides useful characteristics to confirm and de-
limitate the species of ants, and to predict evolutionary trends in behavior and reproductive
biology (Boudinot, 2013). The important characteristic of male morphology and genitalia
that used for species delimitation were highlighted in the following previous studies: in the
genus Odontomachus (Satria et al., 2015); in the genus Opamyrma (Yamada et al., 2020); in
the genus Metapone (Wang et al., 2019); in the genus Pheidole (Wang et al., 2018); in the ge-
nus Dinoponera (Lenhart et al., 2013; Tozetto & Lattke, 2020): in the genus Cardiocondyla
(Schmidt & Heinze, 2017). In the case of the genus Odontomachus, where the taxonomy
problems of Odontomachus rixosus complex confused the myrmecologist for decades, then
it can be resolved by using the information of the morphology and genitalia of the male
caste (Satria et al., 2015). However, the study of the male genitalia in the genus Leptogenys
is still limited, Trager & Johnson (1988) confirmed the status of Leptogenys elongata (Buck-
ley, 1866) and L. manni (Buckley, 1866). They stated that the study of male genitalia is im-
portant in future revisionary work on Leptogenys (Trager & Johnson 1988). Lattke (2011)
used male morphology as part of his argument for synonymising L. mexicana (Mayr, 1870)
with L. elongata (Buckley, 1866).
