Neaetha aegyptiaca Denis, 1947 a: 78 , pl. 5, f. 14-16 (Dmf);

Neaetha aegiptiaca Prószyński, 1984 a: 93 (f).

2018 -Prószyński - split into two species:

Evaneg aegiptiaca Prószyński, 2017 sp. n. (f) and Hyllus aegiptiacus ( Denis, 1947) (m) comb. n.

Material: holotype female " 1936.10.3 Neaetha aegyptiaca J. Denis. Sitra , Egypt, 14-16. 6. 1935. Omer-Cooper Siwa Exped. 1935. det\. J. Denis, 1939", NH Museum, London .

Remark. Denis 1947: 78, pl. 5, f. 14-16 described a composite species Neaetha aegyptiaca , now discovered to consist of one female 6 * (from Sitra) hereby described as Evaneg aegiptiaca Prószynski, 2017 sp. n. with designated holotype of that species ( Fig. 10 L-M), and a male (holotype of the original species, from Siwa) here reclassified as Hyllus aegiptiacus ( Denis, 1947) comb. n. ( Fig. 10N ), the transfer being based on palp similarity with Hyllus semicupreus ( Fig. 10O ). Original description of both female and male, now separated into two different genera, is provided as facsimiles below ( Fig. 11 ). There are no hints, in the original description by Denis, about possible identity of the third specimen - a female from Gara. Map of distribution of these three specimen is shown in Fig. 11 , long distance between their collecting localities should warn Denis that their conspecificity was highly doubtful.

Diagnosis. Key character is shown on Figs 10 L-M, comparative background of remaining species is shown on Figs 10 (documentation of differences with originally mismatched male - see Figs 10N ).

Description. See facsimiles below ( Fig. 11 ).

Therefore:

Neaetha aegyptiaca Denis, 1947 (in part - female) = Evaneg aegiptiaca Prószynski, 2017 sp. n.

Neaetha aegyptiaca Denis, 1947 (in part - male) = Hyllus aegiptiacus ( Denis, 1947) comb. n.

6 Drawing of epigyne shown on Fig. 10L was made with the microscope and drawing apparatus used by F. R. Wanless in his laboratory, to test effectiveness of his methods, as appeared - much inferior to usage of ocular grid (all drawings by Prószyński). Drawing apparatus gave fixed small dimensions of drawing projected on paper from minute object on microscopic slide, with noticeable loss of details during direct observation trough microscope, ocular grid gave freedom of selecting size of drawings and impaired direct observation through microscope of examined object, the speed of work using either methods by an experienced researcher was comparable.

Evaneg praeclara (Prószyński & Wesolowska in Prószyński, 2003) - pending correction of identification

New photographs provided by Mr. Amir Weinstein demonstrate that Israeli specimens from Judean foothill and Tel Aviv area ( Figs 4J 1-M ) cannot be conspecific with Yemeni specimens ( Figs 10 C-D), presumably also differ from specimens from Arava Valley. The species E. praeclara was delimited by merging " Pellenes praecinctus ": Prószyński, 1984 a: 104 and " Evarcha praecinctus ": Wesolowska & van Harten, 1994: 25, f. 52-58 (both separated from synonymy of Mogrus praecinctus Simon, 1890 ). It appears that " Evarcha praeclara " is a group of species, including possibly more species not yet distinguished, deserving revision. Nomenclatorical correction should be delayed until results of revision of these species would be available.
