Hamata View in CoL gen. nov.

Type species. Hamata coralliformis View in CoL sp. nov., here designated.

Description. Body medium-sized. Forewing with black patches along costal margin, at each end of brochosome field. Basal triangles of mesonotum indistinct. Crown fore margin weakly produced and rounded apically, head slightly narrower than pronotum, coronal suture indistinct. Ocelli rudimentary. Face short, anteclypeus relatively long, apex narrow, lorum large. Pronotum with hind margin concave. Forewing with first and third apical cells wide; fourth apical cell very short and narrow, shorter than half length of third apical cell; AA and AP absent. Hind wing venation usual for Erythroneurini, RA absent.

Abdominal apodemes 2S in male very broad and long. Male terminalia. Anal tube without appendages. Genital capsule spherical, well sclerotized. Pygofer lobe with transverse rows of microsetae in the middle, without macrosetae; dorsal appendage lamellate, articulated to lobe; ventral appendage arising from ventro-caudal angle of lobe. Subgenital plate broad and short, slightly surpassing hind margin of pygofer lobe, mitten-shaped, pointed at apex and near midlength of outer margin, with oblique row of macrosetae from subapical inner margin to middle outer margin, with irregular rows of rigid microsetae along outer margin. Style with apical part falcate, curved outwards, with several sensory pits near preapical lobe. Connective V-shaped, manubrium and central lobe well developed. Aedeagal shaft tubular, provided with process; dorsal apodeme developed; preatrium rudimentary.

Diagnosis. The body shape and color pattern of the new genus resemble those of Thailus Mahmood, 1967 , but black patches are present on the vertex and pronotum, and at both ends of the brochosome field of the forewing. The male genitalia are quite different from those of Thailus : the anal tube appendage is absent; the pygofer lacks macrosetae on its side; the subgenital plate is flattened transversely and mitten-shaped; and the style is curved laterad apically.

Etymology. The generic name is a newly-created noun, derived from the Latin adjective “ hamatus ” which means “hooked”, referring to the hooked style. The gender is feminine.

Diversity and distribution. The genus is described as monotypic from southern China.
