Anemadus sengleti Giachino & Vailati, 1993

( Figs 1, 2 , 8–13 , 18 )

Anemadus sengleti Giachino & Vailati, 1993: 138 (type locality: Iran, Lorestan, Dizgarân , 33°44′N 46°59′E).

Material examined. Iran: Isfahan Province, Padena, Kohangan Village , Kohangan Cave , 30°53′31.9″N 51°38′54.1″E, 2196 m, 11.v.2016, M.S. Tahami & Y. Bakhshi leg., parahypogean habitat, 2 females ( JRUC, ZM- CBSU); Kohgiluyeh and Boyer-Ahmad Province , Pataveh Village , Deh Sheykh Cave, 30°57′22″N 51°14′17″E, 1735 m, 17.x.2015, M.S. Tahami, Y. Bakhshi, M.J. Malek Hoseini & Z. Khazaei leg., parahypogean and hypogean habitats, 2 males, 2 females ( JRUC, ZM-CBSU).

Supplementary description. Body length 3.7 mm in male, 3.5 mm in female. Body pale brown with dark brown head, completely pale brown in subteneral specimens ( Figs. 1–2 ).

Male. Apex of elytra regularly rounded ( Fig. 1 ). Tergum 9 of genital segment with apex narrow, regularly rounded ( Fig. 9 , t9). Pleurite 9 with narrow, regularly rounded apex in ventral view ( Fig. 9 , pla9). Aedeagus with median lobe widely rounded, with subapical lateral constriction forming arrowhead-shaped apex in dorsal view ( Giachino & Vailati 1993: 140, fig. 247; Fig. 8 ). Valves of genital orifice elongate, pointed apically ( Fig. 8 ). Endophallus in examined specimen partly everted, with baso-medial sclerotized structures divided into two parts: a basal one, consisting of two parallel differentiated rows of strong spines and basal longer phanerae of undifferentiated spines, and a medial one, consisting of two parallel phanerae of undifferentiated spines ( Giachino & Vailati 1993: 140, fig. 246; Fig. 8 , en). Paramere significantly longer than aedeagus, with apex reversed outwards onto rounded points, with small apical outer seta and several inner setae ( Fig. 8 , pa).

Female. Apex of elytron pointed in female ( Fig. 2 ). Tergite 8 regularly rounded, medially with rounded posterior elongation ( Fig. 10 ). Ventrite 8 with posterior margin weakly, widely emarginate medially ( Fig. 11 ), spiculum ventrale with convergent sides, widely triangular, anterior margin regularly rounded ( Fig. 11 , sv). Tergite 10 regularly rounded posteriorly, with setae of different sizes regularly dispersed in posterior part ( Fig. 12 , t10). Coxite with basal seta present ( Fig. 12 , co). Genital annulus small, its diameter less than 1/3 of the maximal width of tergite 10 ( Fig. 13 , ga).

Remarks. This species was described based on a single male from Iran, Lorestan, Dizgarân ( Giachino & Vailati 1993, Perreau et al. 2017). It was classified as the only member of the Anemadus sengleti species group ( Giachino & Vailati 1993, Perreau 2000). The combination of characters that separate this species from similar members of the A. pellitus species group include the unique shape of the aedeagus, with the median lobe having an arrowhead-shaped apex, and the absence of the central group of spines in the endophallus (species of the A. pellitus species group have the aedeagus narrowing to a simple, narrow apex of the median lobe, and the endophallus with a central group of large spines (Giachino & Vailati 1993)).

We have not examined the male holotype of A. sengleti , but the apex of aedeagus in material examined here ( Fig. 8 ) corresponds well with the illustration of the same structure published in Giachino & Vailati (1993: 140, fig. 247).

Distribution. Endemic Iranian species ( Fig. 18 ), first records from Isfahan and Kohgiluyeh and Boyer-Ahmad Provinces.
