Simpligena gen. nov.

urn:lsid:zoobank.org:act:A3054AE7-6845-4781-9035-4D078C72821D

Type species: Simpligena auromarginea sp. nov.

Diagnosis:

The morphology of the male genitalia makes Simpligena gen. nov. unique. The large and broad tegumen without any of the “normal“ appendages as uncus, socii or gnathos, as well as the large phallus and small valva separate it from all known genera and species of the family. Simpligena auromarginea shows some resemblance with Hystrichophora Walsingham, 1879 which has falcate forewings and male genitalia with a large tegumen and a large and curved phallus as in the present new genus. However, the uncus in Hystrichophora is well developed, and in the female genitalia the signa are different, and the ductus seminalis has a different position ( Agassiz, 2011; Agassiz & Aarvik, 2014; Razowski, 2015).

Description:

Head: Roughly scaled; labial palp 1.4 times diameter of eye, terminal segment short, barely visible due to scaling of second segment; antenna with appressed scales, distally serrate.

Thorax: smooth-scaled. Forewing: Apex prolonged; all veins present, Ms developed, M3 and CuA1 from same point. Hindwing: All veins present. M3 and CuA1 short stalked. Legs without sexual modifications in male.

Male genitalia: Tegumen large, broad, posterior corners convex, each with seven stout setae, uncus absent; valva basally broad, apically hooked, sacculus with row of long bristles, basal excavation large, reaching two thirds of the length of valva; caulis long; phallus large, evenly curved, tapered, without cornuti ( Fig. 1 View Figure 1 ).

Female genitalia: Papillae anales basally slender; posterior apophyses shorter than anterior ones; sterigma posteriorly with complex paired structure; ostium with sclerotized margins laterally and anteriorly; ductus bursae slender, membranous; ductus seminalis attached to ductus bursae close to entrance of corpus bursae; corpus bursae globular, with two horn-shaped signa; posterior margin of sternum 7 forming wide v-shaped cancavity ( Fig. 2 View Figure 2 ).

Etymology: The name of the genus refers to the peculiar, simplified male genitalia.
