Baya lata

Baya lata View in CoL sp. nov.

( Figs 1 View FIGURE 1 , 4 View FIGURE 4 a–e)

Description. Ground color ( Figs 4 View FIGURE 4 a–e) beige, eyes grey, lower midline of frontoclypeal area and anteclypeus infuscated, basal triangles of mesonotum dark, forewing with brown longitudinal stripe near outer margin. Pronotum with reticulate sculpture. Head narrower than pronotum, coronal suture distinct; anteclypeus much wider than in type species. Brown stripe on forewing lightened apically.

Pygofer side ( Fig. 1a View FIGURE 1 ) with 2 distinct processes and 2 small protrusions on lower margin, upper process extended from outer surface, lower process on inner edge, larger than upper one, 2 lowest protrusions very close to each other. Subgenital plate ( Figs 1a, b View FIGURE 1 ) with 2 macrosetae in central part, near outer margin, base of plate with two enlarged macrosetae, with more microsetae on ventral side but marginal microsetae greatly reduced. Style ( Fig. 1c View FIGURE 1 ) with apical part thickened and slightly serrated subapically, preapical lobe small, near midlength. Connective ( Fig. 1d View FIGURE 1 ) without central lobe. Aedeagal shaft ( Figs 1e, f View FIGURE 1 ) with lateral lamella broad, rectangular, with paired processes extended from lower apical angle, process 3-branched, antler-like; dorsal apodeme long; gonopore near shaft midlength.

Diagnosis. The new species can be easily distinguished from the type species by the presence of marginal macrosetae in the central part of the subgenital plate and the 3-branched apical processes of the aedeagal shaft. The pygofer lobe of the new species is also longer and the style is thicker apically.

Measurement. Male length 4.6mm.

Material examined. Holotype ³, PAPUA NEW GUINEA, Morobe, Tekadu , 7°38'S, 146°34'E, 01–20 iv 2000, Malaise trap, coll. T. Sears & Binatung Brigade ( UCD). GoogleMaps

Etymology. The new specific epithet is derived from the Latin adjective “ latus ” which means “broad”, referring to the broad lateral lamella of the aedeagal shaft.
