Mesosoma light brown; lateral margin of torulus light and raised; OOL:POL 1.52; Weber length 1.31 × mesoscutellum length; fore wing length 2.60 × width. Male genitalia: harpe finger-shaped in ventral and dorsal view; harpe/gvc index 1.05; dorsomedial margins of harpes not touching at distodorsal margin of gvc, dorsomedial margin of harpe straight and slightly diverging distolaterally in basal half, straight and parallel to other harpe in apical half, apex of harpe slightly pointed; lateral margin of harpe convex; harpe with at least four lateral setae restricted to apical half; gvc width more than three quarters of gvc length; gvc width equal to distal gvc width; genitalia weakly sclerotized with strongest sclerotization at lateral gvc; genital length 2.67 × gvc width.
Etymology
The species is named after Eärendil, a character of J.R.R. Tolkien’s mythology who carried a star across the sky. The light of Eärendil`s star was content of the Phial of Galadriel, a gift to use in dark places from Galadriel to Frodo Baggins, which was essential for Frodo and Samwise Gamgee to escape from death. The light of Eärendil refers to the description of new species of a Dark Taxon, to shed light into the dark, and to the rather light coloured species.

Remarks
Comparison with similar species
The male genitalia of C. eaerendili sp. nov. and C. malava sp. nov. are very similar in having weakly sclerotized genitalia with finger-shaped harpes and similar harpe/gvc indices. However, the lateral margin of the harpe in C. eaerendili is convex and straight in C. malava , the dorsomedial margin of the harpe is straight and slightly diverging distolaterally in basal half, straight and parallel to other harpe in apical half in C. eaerendili , and straight and slightly diverging distolaterally from base to apex in C. malava , and there are at least four lateral setae of the harpe distributed along the apical half in C. eaerendili and at least three distributed along the apical quarter in C. malava . In addition, C. eaerendili is overall very light and has a light brown mesosoma (brown in C. malava ), and the flagellomeres of C. eaerendili are slightly wider and shorter than those of C. malava .
