E t y m o l o g y: The name (adj.) is derived from the name of the province where, with one exception, all the localities are situated.

D e s c r i p t i o n: 6.9-7.9 mm. Habitus as in Fig. 1 . Coloration: head, pronotum, and abdominal segments III-VII (or rarely III-VI) blackish brown to black; elytra reddish to reddish yellow, sometimes with the scutellar region weakly infuscate; apex of abdomen (posterior margin – or rarely all – of segment VII, segments VIII-X) reddish to reddish brown; legs yellowish brown; antennae reddish brown.

Head 1.02-1.08 times as long as wide ( Fig. 2 ); posterior angles broadly rounded, moderately marked; puncturation coarse, rather sparse in median dorsal area and very dense on remainder of dorsal surface, with interstices distinctly narrower than diameter of punctures; interstices without trace of microsculpture and glossy; eyes moderately large ( Fig. 2 ), distinctly projecting from lateral contours of head and more than half the length of postocular region in dorsal view. Antennae slender; antennomere III longer than II; IV-V distinctly oblong, preapical antennomeres almost 1.5 times as long as wide.

Pronotum slender, approximately 0.95 times as wide as head and 1.25-1.30 times as wide as long; puncturation similar to that of head ( Fig. 2 ); interstices without microsculpture and glossy, in lateral areas on average narrower than punctures.

Elytra 1.28-1.35 times as wide and at suture as long as or slightly longer than pronotum ( Fig. 2 ); puncturation coarse (coarser than that of head and pronotum), usually welldefined, dense, not arranged in distinct rows; interstices without microreticulation. Hind wings fully developed.

Abdomen slightly narrower than elytra; puncturation fine and dense; interstices with fine, but distinct microreticulation; posterior margin of tergite VII with palisade fringe; tergite VIII with strongly convex posterior margin, without distinct sexual dimorphism.

3: sternite VII distinctly modified, with two fine longitudinal carinae separated by about 1/3 the width of sternite, area between these carinae somewhat impressed and without punctures and pubescence, posterior margin broadly concave ( Fig. 3 ); sternite VIII in the middle with longitudinal impression, on either side of this impression with cluster of modified black stout short setae, and posteriorly with deep U-shaped incision ( Fig. 4 ); ventral process of aedeagus blade-like, apically acute, and with pair of lateral subapical tooth-like projections ( Figs 5-9 ).

♀: sternite VIII posteriorly weakly concave in the middle ( Fig. 10 ).

C o m p a r a t i v e n o t e s: Lobrathium farsicum is distinguished from all its congeners by the distinctive male primary and sexual characters. From similar and geographically close species it is additionally separated as follows:

from L. afghanicum by the darker coloration of head, pronotum, and abdomen, the more marked posterior angles of the head, the less coarse puncturation of the forebody (especially of the elytra), the slightly longer and less convex (cross-section) elytra, and the distinctly more convex posterior margin of the abdominal tergite VII; for illustrations of the aedeagus of L. afghanicum see COIFFAIT (1982);

from L. pravum by the usually uniformly reddish elytra (in L. pravum anterior half blackish), the slightly smaller eyes, and the strongly convex posterior margin of abdominal tergite VIII; for illustrations of the male sexual characters of L. pravum see ASSING & SCHÜLKE (2002);

from L. schillhammeri ASSING & SCHÜLKE 2002 (southeastern Anatolia) by usually uniformly reddish elytra (in L. schillhammeri anterior 2/3-3/4 blackish), the slightly smaller eyes, the more slender pronotum, the irregular puncturation of the elytra (in L. schillhammeri arranged in rows), the strongly convex posterior margin of abdominal tergite VIII, and by the posteriorly weakly concave female sternite VIII; for illustrations of the male sexual characters of L. schillhammeri see ASSING & SCHÜLKE (2002);

from L. wunderlei by usually uniformly reddish elytra (in L. wunderlei anterior 2/3 blackish), the denser puncturation of the head, the less coarse puncturation of the pronotum, and the different shape of the posterior margin of the abdominal tergite VIII (in L. wunderlei almost pointed); for illustrations of the male sexual characters of L. wunderlei see ASSING (2006);

from L. ciliciae BORDONI 1980 (central southern Anatolia) by larger size, darker coloration of the head, pronotum, and abdomen, the larger and more bulging eyes, the much coarser puncturation of the head, the distinctly longer and broader elytra, the less coarse puncturation of the elytra, the fully developed hind wings (in L. cilicae reduced), the shorter legs (especially shorter tibiae), the denser puncturation and more pronounced microsculpture of the abdomen, the more pronounced palisade fringe at the posterior margin of tergite VII, as well as by the strongly convex posterior margin of the abdominal tergite VIII; for illustrations of the male sexual characters of L. ciliciae see ASSING (2004).

from L. reitteri by slightly larger size, darker coloration of the head, pronotum, and abdomen, the reddish elytra, the more pronounced posterior angles of the head, the larger and more bulging eyes, the more slender pronotum, the denser puncturation of the pronotum, the much longer and broader elytra, the much finer and denser puncturation of the elytra, the presence of hind wings, the denser puncturation and the presence of distinct microscupture on the abdomen (in L. reitteri without microsculpture), the presence of a palisade fringe at the posterior margin of the abdominal tergite VII, the more strongly convex posterior margin of the abdominal tergite VIII, and the posteriorly weakly concave female sternite VIII (in L. reitteri convex); for illustrations of the aedeagus of L. reitteri see Solodovnikov (2001);

from L. alaiense by larger size, reddish elytra, denser puncturation of the head, the larger and more bulging eyes, the more oblong and slender pronotum, the much longer and

745

broader elytra, the less coarse puncturation of the elytra, the presence of long hind wings, the presence of a pronounced palisade fringe at the posterior margin of the abdominal tergite VII (in L. alaiense only narrow rudiment present), the more convex posterior margin of the abdominal tergite VIII, and the posteriorly weakly concave female sternite VIII; for illustrations of the aedeagus of L. alaiense see GUSAROV (1995);

from the – evidently closely related – L. novum (BERNHAUER & SCHUBERT 1912) ( Tajikistan, Uzbekistan) by larger eyes, denser puncturation of the pronotum and the elytra, by more defined elytral puncturation, by distinctly longer elytra, the different shape and chaetotaxy of the male sternite VII (in L. novum distinctly concave in the middle of posterior margin and on either side of posterior impression with cluster of dark modified setae), and the shape and chaetotaxy of the male sternite VIII (in L. novum posteriorly less deeply and more broadly incised, and with dark modified setae also in the middle); for illustrations of the – not only somewhat differently shaped, but also smaller – aedeagus of L. novum see GUSAROV (1995). The male sternite VIII of L. novum is illustrated in Fig. 26.

D i s t r i b u t i o n a n d b i o n o m i c s: The known distribution is confined to Fars and Hormozgan provinces, southern Iran ( Map 3 ). The new species is apparently rather common on river banks in this region. The altitudes indicated on the labels range from 840 to 2030 m. Some of the type specimens, all of which were collected in April, are teneral.
