Remarks

The subgenus of Erythraeus (Zaracarus) divided in two species groups: one group has AL without swelling near bases which 6 species have basifemoral setal formula 3-3-3, including E. (Z.) kastaniensis Haitlinger, 2006 , E. (Z.) passidonicus Haitlinger, 2006 , E. (Z.) soleimanii Khanjani, Miromayedi, Rezai-Nahad & Fayaz, 2010, E. (Z.) bibadakiensis Haitlinger, 2011 , E. (Z.) coleopterus Mortazavi, Hajiqanbar & Saboori, 2012 and E. (Z.) hafezi Saboori, Hakimitabar & Mahmoudi, 2014 ( Haitlinger 2006a, 2011; Khanjani et al. 2010; Mortazavi et al. 2012; Mahmoudi et al. 2014) and 5 species including, E. (Z.) tehranicus Haitlinger & Saboori, 1996 , E. (Z.) didonae Haitlinger, 2000 , E. (Z.) kharrazii Saboori, 2000 , E. (Z.) monrealicus Haitlinger, 2012 , and E. (Z.) tuzicus Haitlinger & Šundić, 2015 have basifemoral setal formula 2-2-2 ( Haitlinger and Saboori 1996; Haitlinger 2000, 2012; Saboori 2000; Haitlinger and Šundić 2015).

The other group has AL with swelling near bases which 1 species including E. (Z.) plumatus Tseng et al., 1976 has basifemoral setal formula 3-3-2 ( Tseng et al. 1976; Beron 2008; Mąkol & Wohltmann 2012), 12 species including, E. (Z.) eleonorae Haitlinger, 1987, E. (Z.) lancifer Southcott, 1995, E. (Z.) fabiolae Haitlinger, 1997, E. (Z.) budapestensis Fain & Ripka, 1998 , E. (Z.) rajabii Saboori, 2000, E. (Z.) longipedus Saboori & Nowzari, 2001, E. (Z.) aydinicus Saboori, Cakmak & Nouri-Gonbalani, 2004, E. (Z.) sibuljinicus Haitlinger, 2004, E. (Z.) jinkaensis Haitlinger, 2006, E. (Z.) ruizporterae Mayoral & Barranco, 2008, E. (Z.) perpusillus Kamran, Afzal, Raza, Irfanullah, Bashir & Ahmad, 2009 and E. (Z.) adrianicus Haitlinger, 2012 have basifemoral setal formula 3-3-3 ( Haitlinger 1987, 1997, 2004, 2006b, 2012; Southcott 1995; Fain & Ripka 1998; Saboori 2000; Saboori & Nowzari 2001; Saboori et al. 2004; Mayoral & Barranco 2008; Kamran et al. 2009) and 5 species including, E. (Z.) preciosus Goldarazena & Zhang, 1998, E. (Z.) iranicus Saboori & Akrami, 2001, E. (Z.) ueckermanni Saboori, Nowzari & Bagheri-Zenouz, 2004 , E. (Z.) kurdistaniensis Khanjani & Ueckermann, 2005 and E. (Z.) arminouensis Haitlinger & Łupicki, 2011 have basifemoral setal formula 2-2-2 ( Goldarazena and Zhang 1998; Saboori and Akrami 2001; Saboori et al. 2004; Khanjani and Ueckermann 2005; Haitlinger & Łupicki 2011).

Finding some specimens help us to augment and correct the original description of E. (Z.) coleopterus . We re-examined the type of E. (Z.) coleopterus and compared with Kurdistan specimens. The corrected characters are as follows: fn Ta I–III 25–26, 23, 24, presence of companion seta (Cp) with tectal eupathidia on Ta I and II ( Figs. 4–5 ), presence of Cp on palptarsus and fPp = 0-B-B-BBB2- 5BNωζCp ( Figs. 1–2 ). The specimens collected in Kurdistan province fit the data for the species given by Mortazavi et al. (2012) except for the length of AL setae (70–85 vs. 119 in type specimen), PW (95–107 vs. 119) and the shape of posterior border of dorsal scutum (straight vs. concave) ( Fig. 3 , Table 1), which these differences are interpreted as within the range of species variability. Furthermore, Mortazavi et al. (2012) have mentioned which the "subcapitulum with smooth hypostomal setae and galeal setae" in the text, which is typographical error and based on their figure ( Fig. 3 , page 113) and our study these setae have minute barbs ( Fig. 1 ).

SECOND RECORD OF ERYTHRAEUS (ZARACARUS) COLEOPTERUS

In the key to species of the subgenus Erythraeus (Zaracarus) of the world (larva) presented by Mahmoudi et al. (2014), E. (Z.) eleonorae is missed. They set E. (Z.) kastaniensis , E. (Z.) soleimanii, E. (Z.) bibadakiensis , E. (Z.) coleopterus and E. (Z.) monrealicus in the group AL with swelling near bases whereas these species belong to the species group of the subgenus Erythraeus (Zaracarus) with AL with thin bases ( Haitlinger 2006a, 2011, 2012; Khanjani et al. 2010; Mortazavi et al. 2012). Thus, the corrected key of larval species of this subgenus is presented here. We added E. (Z.) tuzicus in the identification key which was described after Mahmoudi et al. (2014). Also, Mahmoudi et al. (2014) mentioned in their paper a range for E. (Z.) passidonicus whereas this species was described based on single specimen.

Leg setal formula in type and Kurdistan specimens are as follows: Leg I: Ta – 1ω, 18, 2ζ, 1Cp, 25–26n [24n in type specimen only on the right side, 26n in two Kurdistan specimens (ARS- 20160707-1c, 1g)] ( Fig. 4 ); Ti – 2φ, 1 Cp, 1K, 14n; Ge – 10, 1K, 8n; TFe – 5n; BFe – 3n; Tr – 1n. Leg II: Ta – 1ω, 18, 2ζ, 1 Cp, 23n [22n in two Kurdistan specimens only on the right side (ARS- 20160707-1a, 1h) and 24n in one Kurdistan specimen (ARS-20160707-1f) only on the right side] ( Fig. 5 ); Ti – 2φ, 15n; Ge – 8n, 1K; TFe – 5n; BFe – 3n; Tr – 1n. Leg III: Ta – 1ζ, 24n [22n in one Kurdistan specimen (ARS-20160707-1h) only on the left side]; Ti –1φ, 15n; Ge – 8n; TFe – 5n; BFe – 3n; Tr – 1n.

IP = 2870–3188 in Kurdistan specimens (3003 in type specimen) .

Metric data is given in Table 1.
