Type material. HOLOTYPE: IRAN, Osculu , 38.872483°N, 46.8966°E, ♂, 10286, Leg. Khaghaninia, IMTU GoogleMaps . PARATYPE: IRAN, Anali forest , 38.895933°N, 46.779417°E, ♀, 10292, Leg. Khaghaninia, IMTU GoogleMaps .

Diagnosis. Male terga with indistinct pollinose fasciate maculae ( Fig. 5A View FIGURE 5 ); metatibia in male with plate-like apical lamella ( Fig. 8A View FIGURE 8 : marked with white arrow), in female metatibia curved in apical third ( Fig. 7B View FIGURE 7 ); metafemur without ventral calcar ( Fig. 8A View FIGURE 8 ). Similar to Merodon lamellatus from which differs in medium sized process on metatrochanter in male ( Fig. 8A View FIGURE 8 : marked with black arrow), [very small in M. lamellatus ( Fig. 8B View FIGURE 8 : marked with black arrow)], metatibia with larger plate-like apical lamella ( Fig. 8A View FIGURE 8 : marked with white arrow) [smaller in M. lamellatus ( Fig. 8B View FIGURE 8 : marked with white arrow)], and narrow metatibia ( Fig. 8A View FIGURE 8 ) [broader in M. lamellatus ( Fig. 8B View FIGURE 8 )]; male genitalia: anterior surstyle lobe biramous ( Fig. 9A View FIGURE 9 : al), with narrow and elongated interior accessory lobe ( Fig. 9D View FIGURE 9 : il) and angular extension ( Fig. 9A View FIGURE 9 : marked with arrow), while in M. lamellatus the interior accessory lobe is less developed and smaller ( Fig. 9E View FIGURE 9 : il) and extension is broader ( Fig. 9B View FIGURE 9 : marked with arrow). Female can be distinguished from M. lamellatus by angular metatrochanter ( Fig. 7B View FIGURE 7 : marked with black arrow), while rounded in M. lamellatus ( Fig. 7C View FIGURE 7 : marked with black arrow), and two apical tarsomere in M. fulvitarsis black (7B: marked with white arrows), while in M. lamellatus two apical only slightly darker than basal two tarsomeres (7C: marked with white arrows).

Description. Length. Male: 9–10 mm; female: 9–10 mm. MALE ( Figs 5A View FIGURE 5 , 8A View FIGURE 8 , 9 View FIGURE 9 ). Small to medium sized species; terga with indistinct pollinose fasciate maculae ( Fig. 5A View FIGURE 5 ), covered with pale pilosity laterally and black pile medially; metatrochanter with medium sized process ( Fig. 8A View FIGURE 8 : marked with black arrow); metafemur narrow, without ventral protuberance, covered with pile shorter than the width of metafemur ( Fig. 8A View FIGURE 8 ); metatibia with one plate-like, apical lamella ( Fig. 8A View FIGURE 8 : marked with white arrow); basal three tarsomeres of all legs reddish-yellow, apical two black ( Fig. 8A View FIGURE 8 ). Male genitalia: anterior surstyle lobe biramous ( Fig. 9A View FIGURE 9 : al), with narrow and elongated interior accessory lobe ( Fig. 9D View FIGURE 9 : il) and angular extension ( Fig. 9A View FIGURE 9 : marked with arrow); posterior surstyle lobe hook-like ( Fig. 9A View FIGURE 9 : pl); cercus rectangular ( Fig. 9A View FIGURE 9 : c); hypandrium sickle-shaped ( Fig. 9C View FIGURE 9 ), with folded theca ( Fig. 9C View FIGURE 9 : marked with arrow).

FEMALE ( Figs 5B View FIGURE 5 , 7B View FIGURE 7 ). Similar to the male except for normal sexual dimorphism and for the following characteristics: metatrochanter angular ( Fig. 7B View FIGURE 7 : marked with black arrow); metatibia curved in the apical third ( Fig. 7B View FIGURE 7 ); terga with distinct white-greyish pollinose fasciate maculae ( Fig. 5B View FIGURE 5 ); terga with pale pilosity, except black pile medially from posterior half of tergum 2 until tergum 5; tergum 4 with weak transverse depression; tergum 5 with a pair of indistinct, lateral, longitudinal depressions; vertex at the level of ocellar triangle black pilose, frons with medial vitta of few black pile.

Etymology. The adjective “fulvus” (fulvi in genitive) means reddish-yellow, referring to the color of basal three tarsomeres on legs.

Distribution. Merodon fulvitarsis sp. nov. has been recorded in mountainous areas of northern Iran (1220–1540 m asl) ( Fig. 16 View FIGURE 16 ).
