Erythraeus (Zaracarus) hamedanicus sp. nov.

( Figs. 14–28 View FIGURES 14 – 17 View FIGURES 18 – 22 View FIGURES 23 – 28 )

Type material. Holotype and one paratype larvae from firebug, Pyrrhocoris apterus L. ( Hemiptera : Pyrrhocoridae ), College of Agriculture, Bu-Ali Sina University, Hamedan (34° 48´N, 48° 28´E, alitude 1820 m a.s.l.), Iran.

Description. For measurements see table 3.

Dorsum ( Figs. 14–15 View FIGURES 14 – 17 ). Prodorsal scutum with two pairs of barbed setae (AL and PL) and two pairs of barbed sensillae (AM and S). Anterior sensilla (AM) situated in obliquely positioned sockets or trichobothria and two times shorter than posterior sensilla (S), anterior half barbed. Anterolateral setae (AL) expanded basally and acute points with posterolaterals (PL) are as long as half length of AL ( Fig. 15 View FIGURES 14 – 17 ). Scutum almost trapezoid with anterior and posterior margins concave; two pairs of eyes posterolateral to scutum. Opisthosoma with 43 rather long and barbed setae ( Fig. 14 View FIGURES 14 – 17 ). fD = 43.

Ve n te r ( Fig. 16 View FIGURES 14 – 17 ). With a pair of setae between coxae I (1 a) and III (3 a). Opisthogaster with eight pairs of setae.

Gnathosoma ( Figs. 17–19 View FIGURES 14 – 17 View FIGURES 18 – 22 ). Infracapitulum with one subcapitular seta, Hy 48 (51) and one oral plus one adoral seta or 35 (32). Palp five-segmented, femur and genu each with one barbed seta, tibia with three barbed setae with bifurcate claw, tarsus with nine setae including a eupathidium and one solenidion, one of which is long.

Legs ( Figs. 20–28 View FIGURES 18 – 22 View FIGURES 23 – 28 ). Legs six segmented (coxae excluded) with femora divided. Tarsi terminate into two lateral claws and a claw-like empodium. Leg setae barbed. Chaetotaxy of segments as follows: coxae 1-1-1; trochanters 1-1-1; basifemora 2-2-2; telofemora 5-5-5; genua 8+1σ+1κ - 8+1κ - 8; tibiae 14+2ϕ+1Cp+1κ - 15+2ϕ - 15+1ϕ; tarsi 24+2ξ+1ω+1ε - 21+2ξ+1ω - 21+1ξ.

Remarks. The news species belongs to the group of species of which the setal formula of the basifemora are 2-2-2. It is closely related to E. (Z.) kurdistanensis , E. (Z.) iranicus , E. (Z.) perciosus , E. (Z.) budapestensis , E. (Z.) didonae , E. (Z.) tehranicus , E. (Z.) eleonorae and E. (Z.) ueckermanni , E. (Z.) kharrazii . However, it can be distinguished from these species by several differences in measurements and setation patterns (Tables 4–5).

Etymology. This species is named after the city Hamedan, where this species was collected.
