Pachyprotasis kojimai Taeger & Shinohara sp. nov.

( Figs 1 , 2 , 4 )

Pachyprotasis nigronotata [not Kriechbaumer 1874]: Takeuchi 1952: 20; Togashi 1961: 32; 1965: 246, plate 125, 32; 1970: 63; Naito 1982: 574.

Description. FEMALE ( Figs 1 A–F, 2A): Body length 8.5 mm, fore wing 10.0 mm, antenna about 5.5 mm (holotype). Antenna filiform, almost not narrowed toward the apex, last antennomere apically blunt. 3rd antennomere about 1.2 × as long as 4th and 2.0 × as long as 8th. 8th antennomere about 4.0 × as long as broad. Head in dorsal view somewhat narrowed behind the eyes. Postocellar area about 1.8 × as broad as long, almost flat and not distinctly higher than the remaining upper head, lateral postocellar furrows deep. Occipital carina prominent and complete. Distance between the lateral ocelli (postocellar line, POL) about 1.5 × as long as diameter of the median ocellus (OD), ocular ocellar line (OOL) 4 × OD, ocellar-occipital carina line (OOCL) nearly 3 × OD. Frontal area with only slightly elevated ridges with shallow furrow between them, antennal furrows shallow. Clypeus apically roundly emarginated to about 0.4 of its length. Labrum apically almost straight, somewhat reflexed. Malar space slightly longer than OD, distance between the toruli about 2 × OD. Head silky shiny, with very shallow microsculpture and few small distant pits. Microsculpture on the remaining body clearly stronger, less shiny, pits more distinct with distances of about 2–5 × their own diameter. Hairs usually clearly shorter than OD. Apical margin of sternum 7 (hypopygium) slightly emarginate. Lancet with rather flat serrulae.

MALE ( Figs 1 G–L, 2B–C): similar to the female; antennae more slender, 8th antennomere almost 6 × as long as broad. Inner tooth of the claw larger than in female.

Color: alive almost completely pale green, dead specimens fading to straw. Antenna dorsally black (scape may be completely pale), pro- and mesotibiae and their tarsi posteriorly black lined, metatibia dorsally black lined and apically black, metatarsus mainly black, metafemur subapically posteriorly black marked. Area between the ocelli, apices of the mandibles, parts of the down bent areas of the lateral mesoscutal lobes, and middle parts of mesopostnotum black marked. Wings hyaline, pterostigma green, remaining veins predominantly dark.

Variability. Body size 8–10 mm. First antennomere (scape) dorsally more or less black lined or completely pale (e.g., holotype). The median mesoscutal groove and the anterior margin of the median mesoscutal lobe may be narrowly black marked. Metatibia either completely black lined, or subapically with green ring (e.g., holotype).

Haploid chromosome number: 10 ( Naito 1982, given for “ P. nigronotata ”); spermatheca: fig. 246 in Togashi (1970), given for “ P. nigronotata ”. COI barcodes see below (paratypes).
