In this paper, species of the subtribe Dromiusina Bonelli, 1810 from southwestern Saudi Arabia are revised. Eleven species in six genera (Calodromius, Dromius, Mesolestes, Metadromius, Microlestes, and Zolotarevskyella) are recognized. Dromius saudiarabicus Rasool, Abdel-Dayem and Felix, sp. n. is newly described species from Rayda Nature Reserve Asir province. The presence of Metadromius ephippiatus in Saudi Arabia is doubtful. A key is also provided to genera and species level for Dromiusina of Saudi Arabia.
Dromius saudiarabicus sp. n., Dromiusina , revision, Saudi Arabia, taxonomy
The Dromiusina Bonelli, 1810 is the third largest subtribe in the tribe Lebiini of the subfamily Lebiinae, encompassing approximately 735 described species (
Dromiusina are distributed worldwide and are currently classified in 48 genera (
The Dromiusina fauna of the Arabian Peninsula is not completely studied and only 18 species are reported. Five species were listed from United Arab Emirates (
The present study is the third in a series of papers revising the southwestern Saudi Arabian Lebiini (
This review is based on extensive surveys (during 2012–2016) in southwestern Saudi Arabia (Al Baha, Asir, and Jizan provinces) and preserved collections at King Saud University Museum of Arthropods, Saudi Arabia (KSMA) (comprising 2253 specimens). Additional materials, including holotypes and paratypes, were also borrowed for examination from the following museums: British Museum of Natural History, London, UK (BMNH), Natural History Museum Basel, Switzerland (NHMB) and Naturalis Biodiversity Centre, Leiden Netherlands (RMNH). The newly collected materials were deposited in KSMA. Other acronyms of the holotype depositories mentioned in the text are the National Museum of Natural History, Paris, France (MNHN) and the Museum of Natural History, Hungary (MNH).
For collection of species, light trap (LT), hand Picking (HP), pit fall trap (PT) and sticky trap (ST) were used. Male specimens of freshly collected species were dissected for aedeagus, which is boiled in 70 % KOH for 1–2 minutes to eliminate additional tissues and kept in clove oil for 24 hours. The aedeagus were glued on cards or preserved inside a glycerin vial pinned under specimen.
All the species and aedeagus were photographed by Q–imaging Micro Publisher 5.0 RTV camera, attached with a trinocular stereomicroscope (LEICA MZ125). Taken images were joined by software Zerene Staker 1.04. FEI Inspect S50 model (Scanning Electron Microscope) was used to take scanned images.
Total body length (TBL) was measured from the anterior margin of labrum to terminating margin of abdomen along midline; head length (HL) was taken from anterior margin of labrum to anterior margin of pronotum along middle line, while pronotum length (PL) and elytra length (EL) was taken from anterior to posterior margin along the middle line of pronotum and elytra respectively; head width including eyes (HW), pronotum width (PW) and elytra width (EW) were measured at their widest points. Aedeagus length (AL) was measured along its body mass. All the measurements were taken with an ocular micrometer in a stereo-binocular microscope (МБС-9).
Verbatim label data cited for the type specimens of the newly described species have label breaks indicated by a slash (“/”). The chorotypes of species were designated by following the classification of

Rayda Nature Reserve (18°12'N, 42°24'E), 20 km northwest the city of Abha, Asir Province, southwestern Saudi Arabia.
The specific epithet is a Latinized adjective in the masculine form based on country Saudi Arabia, from which the new species is described.
Adults of Dromius saudiarabicus sp. n. have all the features of other members of subgenus Dromius Bonelli, 1810 and can be distinguished from them by the following combination of external features: dorsum of head and pronotum rufous to rufo-testaceous, Elytra dark brown, with testaceous maculae, antennae, mandibles, palpi, and legs; head without microlines, but with mesh pattern isodiametric on the vertex, frons smooth; head longer than wide; tempora long with strongly constricted neck; pronotum not strongly transverse, narrowed and sinuate posteriorly before angles.
Habitus: Body form (Fig.
Externally, Dromius saudiarabicus sp. n. is similar to D. buettikeri Mateu, 1990 and D. meridionalis Dejean, 1825, but it can be differentiated from both species by its dull surface, constricted neck, and shape and internal sac of aedeagus. It can also be separated from D. buettikeri by its comparatively less transverse pronotum, sinuate lateral margin of pronotum and tempora long. It is also separated from D. meridionalis by its slightly sinuate lateral margin of pronotum and absence of two ridges near eyes.
This species was collected at elevation of 1897–2761 m (Fig.
This species is only known from the type locality in the Rayda Nature Reserve, Abha, on the southwestern edge of Al Souda Mountain, in the Asir Highlands of the southwestern of Saudi Arabia (Fig.
