Khanjani, Mohammad, Mirmoayedi, Ali-Naghi, Fayaz, Bahman Asali & Sharifian, Tahereh, 2012, Two new larval species of the genus Erythraeus (Erythraeus) (Acari: Erythraeidae) from Iran, Zootaxa 3479, pp. 52-68 : 63

Erythraeus (Erythraeus) chrysoperlae sp. nov. (n=1)

( Figs. 17–31 )

Type material. Holotype larva from a green lacewing, Chrysoperla kolthoffi (Navas) ( Neuroptera : Chrysopidae ), Shahanjarin, Razan (35º 13ʹ 22ʺ N, 49º 10ʹ 16ʺ E, 1825 m a.s.l), Hamedan Province, 8 June 2009, by A. N. Mirmoayedi.

Diagnosis. Basifemora I–III with three setae, Ti I with 14 seate, palp tarsus with eight setae (including one solenidion and one eupathidion), fD 35, fV 14, NVD 49, IP 2670.

Description. Dorsum ( Figs. 17–18 ). Scutum with two pairs of barbed setae (AL and PL) and two pairs of barbed sensillae (AM and S). Posterior sensilla (S) about 2.5 times longer than anterior sensillary (AM), anterior half-length barbed. Both lateral scutal setae (AL, PL) fully barbed, anterolateral setae (AL) 1.3 times longer than posterolateral setae (PL) ( Fig. 18 ). Scutum almost trapezoid, anterior margin concave; two pairs of eyes posterolateral to scutum, first 17 and second 14 in diameter. Opisthosoma with 35 rather long and barbed setae ( Fig. 17 ). fD = 35. Supracoxal seta of coxa I 4 long ( Fig. 20 ).

Venter ( Fig. 20 ). With two pairs of thickened, short, barbed setae between coxae I (1a 36) and III (3a 25), and coxae I–III with one barbed seta (1b 101; 2b 32; 3b 37). Opisthogaster with seven pairs of setae. fV=14.

Gnathosoma ( Figs. 19 , 21–22 ). Infracapitulum with one pair of subcapitular setae, Hy 35 and one adoral seta Or 30. Distance between setae as follows: Or -Or 60; Hy -Hy 35. Palp five-segmented, femur and genu each with one barbed seta, tibia with three barbed setae and with bifurcate claw 27, 30 long, tarsus with eight setae comprising six smooth setae, a eupathidion and a solenidion (11 long) (0-0-B-B-BBB2-6Nwx). Supracoxal seta 5 long ( Fig. 19 ).

Legs ( Figs. 21–31 ). Legs seven segmented, long and bearing barbed setae, tibiae longer than other segments, femora divided into basi- and telofemora. Tarsi terminate in two lateral claws and a claw-like empodium. Chaetotaxy of segments as follows: coxae 1-1-1; trochanters 1-1-1; basifemora 3-3-3; telofemora 5-5-5; genua 8+1 s +1 k - 8+1 k -8; tibiae 14+2 j +1 k +1 Cp -15+2 j -15+1 j; tarsi 27+ 2 x +1 w +1 e +1 Cp -24+ 2 x +1 w +1 Cp -24+ 1 x. Length of legs solenidia: w I 24; w II 18; e I 4; Cp Ta I 6; Cp Ta II 6; j I 29; j I 43; j II 31; j II 10; j III 18; k Ti I 8; k Ge I 8; k Ge II 10; s I 27. One supra-coxal seta on coxa I, 4 long (fig. 20)

Remarks. The new species belongs to the group species with basifemora setal formula 3-3-3. It can be distinguished from those species by the unique combination of characters and measurements shown in diagnosis, and more extensively by their measurements and setal patterns which are shown in Tables 3, 4 (see more details those tables).

Etymology. The new species is named after the scientific genus name of the host lacewing, Chrysoperla kolthoffi (Navas) ( Neuroptera : Chrysopidae ).
