Unknown.</p><p>Discussion.</p><p>This new species is very similar to  Colastes (Colastes) fragilis (Haliday, 1836), but differs from later by having the first metasomal tergite longer, 1.2–1.3 × longer than its apical width (shorter, not longer than its apical width in  C. fragilis), the pronotum dorsally with lens-shaped shallow depression (without depression in  C. fragilis), the propodeum mostly smooth in basal areas and with distinct basal carina (entirely rugose-reticulate or smooth only on small anterior areas and without basal carina in  C. fragilis), fore wing first abscissa of radial vein (r) long and situated distinctly oblique to pterostigma (short and subvertical or only weakly oblique in  C. fragilis), upper part of pronotum side and metapleuron mainly smooth (mainly rugose-reticulate in  C. fragilis), and the second tergite sometimes striate medio-basally (entirely smooth in  C. fragilis).</p><p>Etymology.</p><p>Named from a combination of the species name fragilis and the Latin suffix - oides (resembling) because the new species is similar to Colastes fragilis.</p><p>Distribution.</p><p>Korean peninsula.</p></div>	https://treatment.plazi.org/id/193B5D17E2AC5EE1A0329E005587E3B3	Public Domain	No known copyright restrictions apply.

Pterostigma pale brown.</p><p>Male. Unknown.</p><p>Discussion.</p><p>This new species is very similar to  C. (C.) ussuricus Belokobylskij, 1996, but differs from later by having the face width 1.4 × height of face and clypeus combined (1.1–1.2 × in  C. ussuricus), antenna 28 - segmented (32–35 - segmented in  C. ussuricus), tergites behind third tergite entirely smooth (fourth in basal 1 / 2 and fifth basally striate in  C. ussuricus), metasoma in posterior 1 / 2 yellow to brownish yellow (metasoma black or sometimes partly dark reddish brown in  C. ussuricus).</p><p>Colastes (C.) semiflavus sp. nov. is also close to  C. (C.) interdictus Belokobylskij, 1998, but differs from later by having the face densely granulate in lower 0.6 (in lower 0.3 in  C. interdictus), the first flagellar segment 3.3 × longer than its apical width (4.0–5.0 × in  C. interdictus), penultimate segment of antenna 2.3 × longer than wide (3.0 × in  C. interdictus), prescutellar depression short (relatively long in  C. interdictus), radial vein (r) of fore wing arising from basal 0.45 of pterostigma (from basal 0.3 of pterostigma in  C. interdictus), third metasomal tergite rugose-reticulate in anterior 0.3–0.4 (third tergite entirely smooth or only sometimes with short striae basally in  C. interdictus), metasoma yellow to brownish yellow in posterior 0.5–0.6 (pale reddish brown behind first tergite in  C. interdictus), and hind tibia in distal 1 / 2 and hind tarsus brown (hind legs entirely yellow in  C. interdictus).</p><p>Etymology.</p><p>Named from the combination of the Latin words semi (half) and flavus (yellow) because metasoma is yellow in its posterior half.</p><p>Distribution.</p><p>Korean peninsula.</p></div>	https://treatment.plazi.org/id/5B74961C1B825CEAAD04DF663D1505E3	Public Domain	No known copyright restrictions apply.

Recurrent vein (m-cu) distinctly antefurcal. Second radiomedial (submarginal) cell weakly narrowed distally, its length 2.5–2.7 × maximum width, 1.7–2.0 × longer than brachial (subdiscal) cell. First abscissa of medial vein (1 - SR + M) weakly sinuate. Distance (1 - CU 1) from nervulus (cu-a) to basal vein (1 - M) 1.2–1.3 × nervulus (cu-a) length.

Medial length of second tergite 0.8–0.9 × its anterior width, 1.3–1.5 × length of third tergite. Hind leg sometimes darkened. Otherwise similar to female.</p><p>Discussion.</p><p>This new species is very similar to  Xenarcha (Xenarcha) pacifica (Belokobylskij, 1998),  comb. nov. (Fig. 8), but differs from later by having the strongly curved temple (less strongly curved in  X. pacifica), the penultimate segment of antenna 2.7–2.8 × longer than wide (2.0–2.3 × in  X. pacifica), pronotum dorsally with wide pronope and high curved transverse carina (with narrow pronope and without visible carina in  X. pacifica), and the first metasomal tergite 1.2–1.3 × longer than its anterior width (1.0–1.1 × in  X. pacifica).</p><p>Etymology.</p><p>Named after the related species Xenarcha pacifica and the Latin word formis (form) because it is similar to this species.</p><p>Distribution.</p><p>Korean peninsula.</p></div>	https://treatment.plazi.org/id/1C9092808EFA57D3B033191E7D5E2B75	Public Domain	No known copyright restrictions apply.
