Genus Processina Yang, Deitz & Li, 2005

Processina Yang, Deitz & Li, 2005: 77

Type species: Processina dashahensis Yang, Deitz & Li, 2005

Description. Body small, length of male including forewing 4.5–6.0 mm. Crown produced slightly anteriorly, median length less than interocular width; crown flat or slightly convex between ocelli but shallow concave at ocelli; with median raised carina or not; ocelli located on or slightly anterior to line between anterior eye angles, lateral clypeal suture extending onto corresponding ocellus; frontoclypeus flattened medially or swollen, anteclypeus convex; clypeal muscle impressions distinct; transclypeal suture visible and entire. Pronotum broader than head, anterior margin arc–produced, posterior margin slightly concave. Exposed part of mesonotum and scutellum triangular, well separated from transverse rectilinear depression located at median, flat or slightly convex behind transverse depression. Forewing translucent, with one r-m and one m-cu crossvein, with four apical cells, base of second more proximal than base of third. Hind femur with apical setal formula 2:1:1.

Male pygofer truncate to nearly angularly produced posteriorly, with microsetae on ventral margin, macrosetae few or absent; process directed posterodorsally, branched or not sub-distally. Subgenital plates long, narrow, their apices reaching or exceeding posterior margin of pygofer, each with biseriate macrosetae basally and uniseriate macrosetae distally on lateral margin, some microsetae dispersed on plates. Style slender or somewhat broad, extending posteriorly beyond apex of connective, with setae at rounded apex. Connective Y-shaped. Aedeagus flattened, shape diverse, paraphyses absent.

Remarks. The revised description is mainly based on Yang, Deitz & Li (2005) but incorporating the variation found in species subsequently added to the genus, including the new species described here.

Diagnosis. Processina is easily distinguished from the other genera of Mileewinae by the following characters: vertex weakly produced anteriorly, median length less than interocular width; thorax with pronotal width distinctly greater than transocular width of head; male pygofer with microsetae on caudal or ventral margin, macrosetae absent or few; subgenital plates long and narrow; style extending posteriorly beyond apex of connective, with apical setae; connective Y-shaped.

Distribution. China (Guizhou, Hunan, Sichuan, Taiwan, Yunnan), Thailand.
