Thorictus eiselti sp. nov. (Figs. 1-3)

Type material. Holotype (unsexed)¡ Canary Islands, Gran Canaria, Cruz sAntonio, 930 m, zem past Založ. 3/20/17, výběr 12/2017, J. Eiselt leg. ( JHAC).

Description. Body small (Fig. 1), brown, covered by short, yellow setae on dorsal surface and short yellow setae on ventral surface. Measurements (mm)¡ TL 1.85 EL 1.10 PL 0.67 EW 0.92 PW 0.90. Head finely punctate with very short, yellow, recumbent setae. Labial palpi entirely brown. Antennae brown, with 11 antennomeres, antennal club compact, with 3 antennomeres, terminal antennomere with short yellow setae. Lateral eyes on head very large (0.07 mm), with large granules. Pronotum as finely punctate as head, covered by short, yellow, recumbent setation. Lateral margin of pronotum very finely dentate. Posterior angles without long yellow setae (Figs. 1-2); latero-apical part of pronotum with spot (dent) ( Fig. 3 ). Ventral posterior pronotal angles without yellow setation. Scutellum small, triangular, without setation. Elytra very finely punctate, covered by short, recumbent, yellow setae; lateral yellow setation erect, short; with two depressions in anterior half near scutellum. Epipleuron finely punctate, anterior angles without bump. Prosternum finely punctate. Mesosternum with small, foveolate punctures. Metasternum finely punctate. Visible abdominal ventrites very finely punctate, covered by very short, recumbent, yellow setae. Striation on first visible abdominal ventrite long. Legs brown, covered by short, yellow setae.

Differential diagnosis. The new species belongs to the Thorictus orientalis species group, according to characters stated by John (1963) and is similar to the species T. canariensis Wollaston, 1862 , T. franzi John, 1967 , T. lindbergi John, 1963 , T. tejedanus John & Andreae, 1967 , and T. wollastoni John, 1963 , but differs from them and other Canarian species by the setation on margin of thorax, long striation on first abdominal ventrite and spot (dent) on latero-apical part of pronotum.

Etymology. Patronymic, dedicated to collector of the new species, Jaromír Eiselt (PlZeň, CZech Republic).
