http://zoobank.org/ 077F0D56-466E-41DB-B6D0-AF45DEAE6B4F ( Figs 13–23 View Figs 13–15 View Figs 16–23 , 27 View Figs 24–27 )

Description – Morphology. Metope elongate, with median carina running from its upper margin to the middle of postclypeus. Coryphe nearly hexagonal, depressed, 2.3 times as wide as long medially, with median carina running from its posterior margin, which is deeply angularly concave, but not reaching its anterior margin ( Fig. 13 View Figs 13–15 ). Ocelli absent. Rostrum reaching hind coxae. Pronotum depressed medially. Mesonotum slightly longer than pronotum, with distinct lateral carinae and smooth median carina. Forewings wide, almost circular, with richly reticulate venation, slightly surpassing tergite VI. Forewing vein sequence: R 2; M 2; CuA 2; CuP 1; Pcu 1; A 1 1. Hind tibia with a single lateral spine medially and with 7–8 apical spines. First metatarsomere narrow, 1.5–2.0 times as long as second one, covered with long setae, with two latero-apical and six intermediate spines. Second metatarsomere covered with short setae ventrally, with two latero-apical spines. Arolium short.

Colouration. Head, pro­ and mesonotum, and legs black, with uniform light yellowish brown punctuation. Metope and pronotum with brown light yellowish carinae. Anteclypeus light yellow, with four elongate dark brown spots. Pedicel brown yellowish. Rostrum with 2nd and 3rd segments light yellow dorsally and dark brown ventrally, with black apex. Forewings brown light yellowish, with dark brown to black spots and dots fused in cells on corium and clavus and brown light yellowish veins. Tegulae and basal cells light yellow. Coxae light yellow, with dark brown areas. Apices of fore and middle tibiae light yellow. Leg spines black apically. Tarsomeres light yellowish brown. Apices of third meta­ tarsomeres and claws dark brown to black. Abdominal sternites dark brown to black, with light yellow hind margins. Sternite VII with wide yellow stripe along hind margin. Abdominal tergites black, with brown yellowish sparse punctation. Anal tube light yellow dorsally, dark brown ventrally, and black inside. Pygofer with light yellow hind margins. Styles light yellow, with dark brown hind margins and brown caudo-dorsal angles.

Male genitalia ( Figs 16–23 View Figs 16–23 ). Pygofer elongate vertically, narrow, with hind margins deeply concave basally (in lateral view) ( Fig. 16 View Figs 16–23 ). Anal tube wide, 1.6 times as long as wide, with deeply concave posterior margin (in dorsal view) ( Fig. 17 View Figs 16–23 ). Anal tube narrowing apically (in lateral view) ( Fig. 18 View Figs 16–23 ). Anal column short and wide. Phallobase elongate, with two latero-apical lobes narrowing apically and weakly serrate ( Fig. 19 View Figs 16–23 , lap) and one elongate and truncate apically dorsal lobe ( Fig. 20 View Figs 16–23 , dl). Phallobase strongly convex ventrally below the aedeagal hooks, with wide processes covering the hooks ( Figs 19, 21 View Figs 16–23 , phbp). Phallobase covered by denticles inside. Ventral phallobase lobe large, with two lateral narrow processes at upper corners ( Fig. 19, 21 View Figs 16–23 , vl). Aedeagus well visible above upper phallobase margin, covered with denticles, with four long and narrow processes ( Fig. 21 View Figs 16–23 , aedp). Connective large, with elongate cup ( Fig. 19 View Figs 16–23 , cc). Styles with wide plate covered by hair-like setae, with small capitulum bifurcated into two processes one of which bearing two teeth (in dorsal view) ( Figs 22, 23 View Figs 16–23 ).

Total body length – 5.0 mm.

Etymology – Species name is derived from Latin adjective “ardua ” – steep referring to the steep slope ( Fig. 1 View Fig ) where the type series was collected.
