Bembidion (Ocydromus) terryerwini sp. nov. from Central Iran (Kerman and Yazd Provinces), described here, belongs to the decorum species group (Ocydromus Clairville, 1806). The new species is compared with the other taxa of this species group occurring in Iran and neighboring regions (Georgia, Armenia, Azerbaijan, Turkey, Iraq, Iran, South Pakistan, Afghanistan, and Turkmenistan).
Central Asia, decorum group, new species, Ocydromus, taxonomy
In unidentified material of Bembidion Latreille, 1802 collected in Iran by our colleagues David Wrase and Peer Schnitter we discovered an unknown species of the subgenus Ocydromus Clairville, 1806 belonging to the species group of decorum Zenker in Panzer, 1801 due to the unicolorous elytra and the presence of microsculpture on the pronotum. This species, later found also in other collections, was compared with abundant material of almost all taxa of the group, formerly studied by
The systematic treatment of the Bembidiina and the geographical acronyms follow Löbl and Löbl (2017). The body length was measured for card-mounted specimens from the front margin of the labrum to the apex of the elytra. Dissections were made using standard techniques. Genitalia and small parts were preserved in Euparal on acetate mounts fixed on the same pin as the specimens.
LT took the photographs with Nikon DSFi1 and Nikon DS-L2 on a Leica Z6 microscope, while Werner Marggi provided the photograph of B. sokolowskyi Fassati, 1957. The drawing of the spermatheca was made by Ivo Gudenzi.
The examined material is preserved in the following collections:

We were able to compare the species herein described with abundant material from several collections (CTVR, PN, DW, PS, JM), except for ispartanum nairicum Iablokoff-Khnzorian, 1976 and sokolowskyi Fassati, 1957 that were compared based on the literature, by original descriptions or other publications. Of sokolowskyi, Werner Marggi kindly provided a photo of the holotype taken in the Coll. Fassati. We also examined the following type material: 1 ♂, paratype of B. semilotum Netolitzky, 1911 “Sultanabad / Th. Strauss [printed] // semilotum [handwritten] / det. Netolitzky [printed] // CO / TYPUS [red, printed]” (CTVR), 2 ♀♀. paratypes of B. hiekei Müller-Motzfeld, 1986 “Turkm., Kopet Dag / Salzquelle 2 Km v. / Tschuli b.Firjusa / 18.9.76, leg. F. Hieke [printed] // PARATYPUS [red, handwritten] // Bembidion [printed] / hiekei n.sp. [handwritten] // det. Müller 1985 [printed]” (PN).
A Bembidion of the subgenus Ocydromus and member of the decorum group; very similar to B. hiekei Müller-Motzfeld, 1986, but recognizable from the latter by a less transverse pronotum with narrow lateral gutter and punctured anterior transverse impression and adjacent area.

(Fig.
Head : maximum width, including eyes, 1.07 mm; interocular distance 0.62 mm; smooth, punctured in the median portion of the frons at the posterior half of the eye; microsculpture present in the posterior portion of the neck. Eyes markedly protruding, temples very short, almost absent. Wide frontal furrows, with a few punctures. Antennae long 2.68 mm.
Pronotum
(Fig.
Elytra : length 3.20 mm, maximum overall width, slightly beyond the middle, 2.00 mm; overall shape slightly ovoid with evident shoulders; completely microsculptured with sharp transverse polygonal sculpticells; intervals flat; striae and punctation evident but superficial, visible also near the apex but disappearing at apex. Macropterous species.
Medium-small sized (1.02 mm), with ventral margin only slightly concave and apical fourth bent ventrally; endophallus almost completely included in the median lobe; extremely elongated apex.
The paratypes generally match with the holotype in color and morphology. The brown color of the elytra may be more or less intense, from reddish to dark brown; the palps may be slightly darkened at apex. The pronotum may be slightly more transverse. The microsculpture of the pronotal disc may be more or less visible; the fine punctation at the anterior transverse pronotal impression, always present and sharp, may show a variable number of punctures. The ♂♂ are long from 4.70 to 5.70 mm and the ♀♀ from 4.80 to 5.70 mm. The length of aedeagus (Fig.
This beautiful species is named in memory of the late Terry Erwin (1940–2020), excellent, very kind, collaborative, and friendly man, and excellent globally acknowledged entomologist, who contributed to the taxonomic research of the tribe Bembidiini through numerous publications (e.g.,
The new species is known from the Kerman and Yazd Provinces, in central Iran.
The species of decorum group currently reported from Iran and neighboring regions are eleven. The decorum group includes species with pronotum microsculptured at least at sides and elytra unicolorous greenish, bluish metallic, or brown.

(O.) decorum subconvexum K. Daniel & J. Daniel, 1902 (Azerbaijan, Armenia, Georgia, Russia: South European Territory, Iran, Turkey); B. (O.) siculum smyrnense Apfelbeck, 1904 (Albania, Bosnia Herzegovina, Bulgaria, Croatia, Greece, Macedonia, Romania, Turkey, Ukraine, Yugoslavia A: Cyprus, Israel, Lebanon, Syria, Turkey); B.

(O.) zolotarewi Reitter, 1910 (Armenia, Georgia, Russia: South European Territory, Iran); B. (O.) semilotum Netolitzky, 1911 (Armenia, Iran, Turkey); B. (O.) hiekei Müller-Motzfeld, 1986 (Iran, Turkmenistan); B. (O.) sokolowskyi Fassati, 1957 (Afghanistan); B. (O.) hasurada pagmanicum Fassati, 1959 (Afghanistan).
