Type locality.

Iran, Prov. Kerman, Rāyen, Goroah, Babtahoune 2700 m, 29°21'14.7"N, 57°20'31.7"E.

Comparative material.

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).

Diagnosis.

A Bembidion of the subgenus Bembidion Ocydromus and member of the Bembidion 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.

Description of holotype

(Fig. 2 ). Total body length 5.20 mm. Coloration: head and pronotum black, with green metallic reflections, elytra brown, scutellar area blackish brown and sutural interval brown at the internal side. Antennae yellow-orange, only slightly darkened from the apical half of antennomere 4. Palps yellow-orange. Legs yellow-orange with femora with faint brown reflections.

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. 6 ): length along the mid line 1.03 mm; width of the anterior margin 0.87 mm, maximum width 1.26 mm, width of base 0.93 mm; pronotal width/pronotal length ratio 1.22; slightly transverse; posterior margin slightly convex at middle, oblique towards the hind angles; anterior margin rectilinear with angles evidently bent ventrally; sides entirely rebordered, narrowing evidently and markedly sinuate towards base with which they form a large right angle, despite of the oblique sides of the base; lateral gutter narrow, of homogeneous width; basal foveae subquadrate, with scattered punctures and long laterobasal carina; median line sharp; anterior transverse impression and neighboring area with numerous (about 20) very sharp punctures; basal transverse impression rugose-punctate. Microsculpture in short, polygonal transverse sculpticells, barely visible on disc.

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.

Male genitalia.

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.

Intraspecific variability.

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. 7 ) ranges from 1.00 to 1.13 mm, the reservoir of the spermatheca (Fig. 3 ) is 0.23 mm long.

Derivatio nominis.

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., Erwin 1971, 1972, 1973, 1974a, b, 1975, 1976, 1977, 1978, 1982, 1984; Erwin and Kavanaugh 1980, 1981, 1999: Erwin et al. 2010: Kavanaugh and Erwin 1992).

Distribution.

The new species is known from the Kerman and Yazd Provinces, in central Iran.

Comparative notes.

The species of Bembidion decorum group currently reported from Iran and neighboring regions are eleven. The Bembidion decorum group includes species with pronotum microsculptured at least at sides and elytra unicolorous greenish, bluish metallic, or brown. Eleven species of this group are currently known from Iran and neighboring regions: Bembidion (Ocydromus) decorum bodemeyeri K. Daniel & J. Daniel, 1902 (Bulgaria, Greece, Macedonia, Turkey); B. (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.) siculum durudense Marggi & Huber, 1999 (Azerbaijan, Armenia, Georgia, Russia: South European Territory, Iran, Turkey); B. (O.) ispartanum ispartanum Netolitzky, 1930 (Armenia, Iran, Israel, Turkey); B. (O.) ispartanum nairicum Iablokoff-Khnzorian, 1976 (Armenia, Georgia); 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). Their aedeagi, except for Bembidion sokolowskyi , are well documented by Müller-Motzfeld (1986). Bembidion terryerwini is distinguishable from the above-mentioned species, excluding Bembidion hiekei , by the brown elytral color; from Bembidion hiekei (Figs 1 and 5 ) by the less transverse pronotum with narrow lateral gutter and the anterior transverse impression and neighboring area with several punctures; from Bembidion hasurada Bembidion pagmanicum by the elytral striae less deeply impressed; from Bembidion semilotum , Bembidion ispartanum Bembidion ispartanum , and Bembidion siculum Bembidion durudense by the yellow-orange femora with faint brown reflections and by the antennae slightly darkened from the fourth antennomere; from Bembidion ispartanum Bembidion nairicum by the antennae with the first three antennomeres light; from Bembidion siculum Bembidion smyrnense and Bembidion siculum Bembidion durudense by the structure of the endophallus and the not darkened femora; from Bembidion zolotarewi by the elytral margins not evidently rounded; from Bembidion decorum Bembidion bodemeyeri and Bembidion decorum Bembidion subconvexum by the elytra less deeply punctate-sulcate and by the structure of the endophallus; from Bembidion sokolowskyi (Fig. 4 ) by the less transverse pronotum with base slightly oblique towards the angles and by the femora not darkened.
