M a t e r i a l. T y p e: Holotype ♂: Iran: Kerman Province, Dalfard, 29̊36 ′ 00.8 ″ N, 056°30 ′ 23.0 ″ E, reared from stem galls of Artemisia aucheri, 20.05.2016 (Moeinadini leg.) (ZMSBUK).

The specimen is pinned from alcohol. Left antenna, anterior frontal, both anterior and left posterior orbital, median vertical, ocellar, dorsocentral and right scutellar setae missing.

Diagnosis. The new species can be easily differentiated from other Palaearctic Hendrella species by having only one large hyaline spot in cell r 1 in combination with entirely dark costal cell. It is similar to H. caloptera sharing yellow antenna and femora and similar wing pattern (basal part of wing brown, cell r 1 with only one large triangular hyaline spot that is restricted to width of the cell, cell cu 2 with one large hyaline spot), differing in having completely brown costal cell as shown by arrow on fig. 2, 1 (in H. caloptera with hyaline area reaching posterior margin of the wing — fig. 2, 2). First flagellomere of antenna in H. kermanensis sp. n. is pointed apicodorsally, the latter character is unique in Hendrella and among Dithricini.

D e s c r i p t i o n. H e a d (fig. 1, 1) yellow, silvery microtrichose. Length: height: width ratio = 1: 1.59: 1.76. Face gently concave as seen in direct lateral view. Frons above lunule with white setulae. Two brown and an additional white frontal and two orbital seta present. Postocular setae and setulae whitish-yellow. Frons rather broad, subquadrate, about as wide as long and 1.6 as wide as eye. Compound eye about 1.6 times as high as long. Gena about 0.55 times length of flagellomere 1. Flagellomere 1 yellowish brown, 1.8 times as long as wide, pointed at apicodorsal angle; arista basally yellow, distal two-thirds black.

Thorax (figs 1, 1–2). Ground color yellowish brown; scutum silvery microtrichose. All setae brownish yellow; setulae white. Scutellum yellow with semi-triangular brown spot basally, silvery microtrichose, bearing one pair of strong scutellar setae, about 0.8 mm in length. Dorsocentral setae situated slightly posterior of suture. Subscutellum and mediotergite dark brown, silvery microtrichose. Calypteres white. Haltere yellow.

Legs yellowish brown, fore femur with 2 rows of brownish yellow posterodorsal and one row of brownish yellow posteroventral setae; legs with brownish setae and setulae (fig. 1, 1).

Wing (fig. 2, 1). Cell bc completely brown, humeral crossvein dark brown. Cell c and pterostigma brown without any hyaline spots, cell r 1 hyaline at very base; dark brown, with one large marginal triangular hyaline spot beyond pterostigma that touches vein R 2+3. Cell r 2+3 completely brown without any hyaline spot; br hyaline from the level of humeral crossvein to radial fork; brown at very base and in apical two thirds; in apical brown part, only one large round hyaline spot as wide as cell present posterior to pterostigma. Cell r 4+5 with large hyaline spot as wide as cell anterior to dm-cu crossvein, and long preapical transverse hyaline spot starting at the level of end of R 2+3 and penetrating into cell m and ending in wing margin. Cell bm and bcu brown only in apical one third. Cell dm completely brown, with one large oval hyaline spot posterior to hyaline spot in r 1. Cell m with two hyaline spots, the proximal triangular one is as wide as cell and distal one extending into cell r 4+5; cell cu 2 brown with one large hyaline spot extending into anal lobe and ending in wing margin. Anal lobe mostly brown; hyaline at very base and apex of vein A 1 +Cu 2. Vein R 4+5 with 1 setula ventrally.

Abdomen with tergites completely black, grayish microtrichose, tergite 5 subshining black, about as long as preceding two abdominal tergites; setae and setulae brown.

Male genitalia as in other species of the genus: epandrium oval (figs 1, 3–4); glans moderately long (fig. 1, 6), ejaculatory apodeme as in fig. 1, 5.

M e a s u r e m e n t s. Body length 3.25 mm, wing length 3.25 mm.

Etymology. The new species name refers to Kerman Province, in which this species was found.

Host plant. This species has been reared from stem galls on Artemisia aucheri (fig. 2, 3) along with Oedaspis ragdai Hering. As all stem galls on A. aucheri were of similar size and shape and placed in the same container, it is not clear which one of them actually belonged to H. kermanensis sp. n.
