Genus Siccanda Abdalla & Mansell   gen. nov.


Nemopterella Banks, 1910: 454   (partim)

Etymology. The genus name is derived from the Latin adjective siccaneus (dry soil) for the dry areas where the species occurs. Gender feminine as derived from the name of the type species.

Type species. Nemopterella arenaria Tjeder, 1967   ( Fig. 29 View FIGURE 29 ), designated here.

Diagnosis. Small to medium-sized species, distinguished by: (1) faintly visible light yellowish pterostigma ( Fig. 24b View FIGURES 20–24 ); (2) blackish greyish body ( Fig. 29 View FIGURE 29 ); (3) terminal segment of antennae ending with acute bare tooth ( Fig. 25 View FIGURES 25–27 ); (4) faint brown shading over Cx ( Fig. 29 View FIGURE 29 ); (5) between 20–32 Cx; (6) indistinct body stripes ( Figs 20 View FIGURES 20–24 , 28 View FIGURE 28 , 29 View FIGURE 29 ), (7) subcostal, radial and anal areas never tinged ( Figs 24 a View FIGURES 20–24 ); (8) costal cells before and beyond pterostigma never tinged ( Fig. 24b View FIGURES 20–24 ); (9) whitish apical portion of hind wings clothed with white hairs ( Fig. 27 View FIGURES 25–27 ); (10) tergite 5 of abdomen with pleuritocavae ( Fig. 20 View FIGURES 20–24 ); (11) Frons above antennae with pair of yellow transverse spots along the postfrontal suture ( Fig. 26 View FIGURES 25–27 ); (12) ventral side of the thorax tinged dark brown.

Description. Size (mm). Male: body length 7.8 (6.5–10); forewing 21.9 (20.3–26.9); hind wing 49.1 (43.4–62); antenna 20.4 (18.9–24.3); Female: body length 9.8 (9.2–10.6); forewing 21.2 (20.3–21.9); hindwing 45.1 (43.4– 46.7); antenna 12.5 (11.1–12.8). (N = 47).

Head. Yellow, medium-sized with large prominent eyes that are relatively smaller and more widely separated in females than males. Vertex brown with yellow hind margin, distinctly broader in females than males. Frons above antennae markedly elevated with a pair of yellow transverse spots along postfrontal suture. Palpi brown. Antennae in males much longer than females, reaching beyond pterostigma, yellow proximally, darkened distally, covered in black setae becoming denser towards apex. Apical segment short, blackish, ending in acute bare tooth.

Thorax ( Fig. 28 View FIGURE 28 ). Shape as in Nemopterella   . Markedly pruinose. Pronotum dark greyish brown without distinct stripes and with yellowish hind margin. Fore and hind margins covered in long, erect black hairs intermixed with long fine hairs. Fine, long white hairs situated behind the fore-margin hairs. Distal anterior lateral portions of pronotum covered in mixture of long black and white hairs. Setation in males much denser and longer than females. Mesonotum dark greyish with two greyish portions on anterior lateral sides of prescutum and central greyish yellow portion between prescutum and mesoscutellum. Mesonotum ventral sides tinged greyish dark brown. Mesonotum very hairy particularly on prescutum disc, densely covered with long hairs, mainly black on prescutum and mesoscutum and white in mesoscutellum, also with some white hairs admixed with the black hairs on the antero-lateral sides of prescutum and on mesoscutum disc. Metanotum yellowish with two clusters of long white hairs laterally. Legs as in Nemopterella   but coxae tinged dark brown.

Forewings ( Fig. 29 View FIGURE 29 ). Broader in females than males with faintly greyish membrane. Males with slightly falcate apex and shallow emargination before apex, ending in a narrowly rounded apex while in females the apex is broadly rounded. Pterostigma small with light yellowish tinge. Costal cells, subcostal, radial and anal areas before and beyond pterostigma not tinged as in Nemia   and N emopterella. Proximal Cx slightly shaded with brown. From 20–32 Cx present.

Abdomen ( Fig. 20 View FIGURES 20–24 ) as in Nemopterell a. Blackish with reddish yellow hind margins to tergites dorsally, without distinct stripes, yellowish ventrally. Setation different between sexes, long, dense and white in males, short, sparse and black in females.
