description: Hylaeus (Nesoprosopis) jirisanensis Chen and Xu, sp. nov.
(Figs. 7–12, 20)
Diagnosis. Male: more or less large size; marks on face well developed; propodeal TRN, OBL and lateral carinae indistinct, anterior portion of propodeal with longitudinal wrinkles; scape slightly turbinate broadened. Apical process of S8 similar to H. dathei sp. nov., but it is longer and curved in the lateral view.
Description. Male (Holotype). Measurements: BL 5.65mm; WL 3.94mm; HL 1.79mm; HW 1.88mm; CI 1.31; SI 1.95.
Coloration: Black. The following yellowish: mark on clypeus reverse T-shape, except anterior tentorial pit and upper margin; lateral face marks always filling paraocular areas and ending acutely along eye margins at the level of antennal sockets; anterior stripe on scape; linear marks on lateral portions of pronotal collar; mark on pronotal lobe; lateral mark on fore tibia, basal 1/5 of middle tibia, basal 1/2 of hind tibia, most parts of all basitarsi. Underside of flagellum brown; tegula black; all mediotarsus and distitarsus brown; veins and stigma light brown.
Structure: Scape slightly turbinate broadened; face moderately shiny with minute to fine punctures; clypeus longitudinally lineolate-reticulate, lower portion slightly convex, with minute sparse punctures; paraocular area longitudinally lineolate-reticulate with fine and close to sparse punctures, slightly convex; frons pit-reticulation, with fine dense punctures; punctures along eye margins larger and sparser; facial fovea indistinct; gena narrower than eyes in lateral view, moderately shiny with minute to fine and close to sparse punctures; pronotal collar roundly thickened, attenuated toward middle; mesoscutum slightly convex, moderately shiny with fine close punctures; scutellum moderately shiny with fine and close punctures which are larger and sparserthan those on mesoscutum; metanotum pit-reticulation, moderately shiny; mesopleuron moderately shiny with larger and sparser punctures; propodeal TRN, OBL and lateral carinae indistinct, anterior portion of propodeal with longitudinal wrinkles, punctures on lateral area minute and dense; T1 shiny with particularly minute and scattered punctures, T2 and following terga moderately shiny with much more and closer punctures.
Pilosity: Hairs on vertex yellow, dense and long; hairs on apical margin of clypeus yellow, short and very sparse; pronotal collar and pronotal lobe with short dense yellow hairs; hairs on mesoscutum and scutellum white, extremely short and sparse; hairs on metanotum yellow, long and dense, lateral portion much longer and denser; hairs on T1 nearly absent, hairs on T2 and the following terga white, very short and sparse.
Terminalia: See Figs. 7–12. Apical lobe of S7 reduced and without hairs, subtriangular. S8 more or less rhombiform, apical process slender, taper.
