Zaragozachthonius (Pseudoscorpiones, Chthoniidae), a new genus with species in Italy and the Balkan peninsula Author Gardini, Giulio text Zootaxa 2020 2020-12-11 4894 4 535 548 journal article 9328 10.11646/zootaxa.4894.4.3 462ff1ea-f7e9-4324-a29c-2c025bf1405b 1175-5326 4316705 F3ED9338-25C3-41CC-A0E8-8CBB35E74536 Genus Zaragozachthonius n. gen. Diagnosis. Genus of the tribe Chthoniini with fusiform chelal hand constricted between trichobothria ib-isb and base of fixed finger, base of hand abruptly constricted paraxially; hand without distoventral hollow; distal end of hand and bases of chelal fingers with strongly sclerotized condylar complex, without medial protuberance between chelal condyles; proximal portion of hand with 4 setae in adults and tritonymphs ( ph 3 present); fixed chelal finger straight in lateral view; axis of fixed chelal finger apically forming a widely obtuse angle; chelal fingers with closeset teeth, distinctly reclined backwards; distal row of fixed chelal finger without a modified subdistal tooth ( mt ); tip of fixed chelal finger of both sexes with an antiaxial accessory tooth ( td ) and with a weak hollow on paraxial face, without subdistal protuberance ( sp ); base of movable chelal finger with an enlarged sclerotized condyle ( bc ), internal proximal apodeme ( ap ) well developed; trichobothrium sb closer to b than to st ; coupled sensilla pc at level of sb or between sb and b ; antiaxial lyrifissures ( ma 1 , ma 2 ) of movable chelal finger present. Coxae II and III with coxal spines arranged in rounded patches; bisetose intercoxal tubercle present between coxae III and IV; distal marginal seta of pedipalpal coxa ( dps ) distinctly longer than that ( dcs ) of coxa I; in addition to the stigmatal setae, sternite III in both sexes with 8–10 posterior setae, of which the lateral one ( ls ) on each side is reduced in size. Male genitalia without a median hiatus ( mh ) between setae of each row of guard–setae ( gs ). Type species. Zaragozachthonius siculus n. sp. Etymology. The genus is dedicated to Juan Antonio Zaragoza (Alicante, Spain ) in recognition of his great contribution to the knowledge of Mediterranean pseudoscorpions. The generic name is the union of the surname Zaragoza and Chthonius , a typical suffix within the Chthonioidea. It is masculine in gender. Distribution. Italy (Apennines, Sicily ), Republic of North Macedonia . Remarks. With reference to the 17 characters useful to distinguish the nine Chthonius –related genera (with coxal spines on coxae II and III) listed by Zaragoza (2017: 19 , table 1), Zaragozachthonius n. gen. shares with Chthonius all characters but the presence of an antiaxial accessory tooth ( td ) on the tip of the fixed chelal finger ( td absent in Chthonius ), and the presence of a strongly sclerotized condylar complex on the base of movable chelal finger (condylar complex absent in Chthonius ). Zaragozachthonius n. gen. shares with Globochthonius all char-acters—also the position of coupled sensilla pc on movable chelal finger ( 1 )—but the presence of chelal hand with fusiform facies (lagyniform facies in Globochthonius ) and the absence of a dorso–paraxial hump at the base of chelal hand (hump present in Globochthonius ). Concerning the chelal fingers dentition, only a few species of Globochthonius have teeth that are more or less close-set, distinctly reclined backwards, as Globochthonius abnormis (Dumitresco and Orghidan, 1964) or G. vandeli (Beier, 1939) ( Ćurčić 1974 ) . To facilitate identification, Zaragozachthonius n. gen. is compared with the other Chthonius –related genera and differences are reported in the following key. (1) Gardini (2010: 57) erroneously wrote that coupled sensilla pc (as p 1 ) in Globochthonius globifer (Simon, 1879) are situated mainly between trichobothria sb and st , rarely near or just distad of sb : they were correctly given on page 56 ( Figs 7–8 ) between b -sb.
