Halictus problematicus – Hirashima 1957: 15. Lasioglossum ( Evylaeus ) problematicum – Ebmer 1978: 311–312. — Ebmer 1996: 282; Ebmer 2002: 865–867 (♂). — Ebmer 2006: 563. — Murao et al . 2006: 50. Evylaeus ( Glauchalictus ) problematicus – Pesenko 2007a: 26. — Pesenko 2007b: 85 (in key), 95 (in key), 115. Diagnosis This species is closely related to Lasioglossum alishanense Murao sp. nov., L . sanitarium (Blüthgen, 1926) and L . sichuanense Fan & Ebmer, 1992 from the northern Oriental Region, as stated above. For the differences between this species and L . alishanense , see the Key. It is also separated from the remaining two species by having the disc of the male S5 without an apical depression (Fig. 14B).

Basal area approximately 2.3 × as wide as long in female, 3 × in male; basal elevation of female moderately developed, that of male absent; distal process of female slender, nearly as long as basal area, and without lateral projection, that of male absent; keel of distal process narrow, apically pointed; labral fimbria acutely pointed at apex in both sexes. STERNA. S4 medially with shallow groove on apical half; apical margin nearly straight. S5 without apical depression, medially weakly swollen and apico-medially cleaved; apical margin gently incurved. S6 normally shaped, not modified. S7–S8 (Fig. 16F): S7 with elongate, apically rounded median process, apex exceeding S8; S8 without median process. MALE GENITALIA (Fig. 16 A–E). Gonobase nearly flat at bottom, ventral arms connected with each other at upper ends; gonocoxite smooth, gently sloped in lateral view, and inner dorsal margin gently angulate at approximately basal 1/3; gonostylus large, located at top of gonocoxite, with dense short setae on inner surface; ventral retrorse lobe moderately long but not reaching gonobase, with dense short setae ventrally and relatively long blunt setae laterally; penis valve higher than gonocoxite, with high cleft on top. Distribution Russian Far East (Sakhalin) and Japan (Hokkaido, northern to central Honshu). Ebmer (1978, 2006) recorded this species from Primorsky and North Korea, respectively, based on female specimens. These records are not included in this paper, because the female cannot be clearly separated from that of some of the related species. Flight period Female: May to September in Hokkaido, Japan. Male: August to October. The flight record of females is based on specimens collected from the eastern part of Hokkaido, Japan. This record can be considered accurate, because one of the related species, L. virideglaucum Ebmer & Sakagami, does not sympatrically inhabit this area. Flower records In Japan this species visits the following 19 species in 6 families: Apiaceae: Angelica ursina (Rupr.) Maxim. Asteraceae: Anaphalis margaritacea (L.) Benth. & Hook. f. subsp. margaritacea Aster glehnii F. Schmidt; Cirsium setosum (Willd.) M. Bieb.; Crepidiastrum denticulatum (Houtt.) J.H. Pak & Kawano; Erigeron annuus (L.) Pers.; Hieracium umbellatum L.; Picris hieracioides subsp. japonica (Thunb.) Krylov; Rudbeckia laciniata L.; Senecio pseudoarnica Less.; Solidago altissima L.; S. virgaurea L. subsp. asiatica (Nakai ex H. Hara) Kitam. ex H. Hara var. asiatica Nakai ex H. Hara; S. virgaulea L. subsp. leiocarpa (Benth.) Hultén; Sonchus brachyotus DC.; Taraxacum sp. Brassicaceae: Barbarea orthoceras Ledeb. Geraniaceae: Geranium thunbergii Siebold ex Lindl. & Paxton. Lamiaceae: Isodon sp. Rosaceae: Sorbaria sorbifolia (L.) A. Braun. Biological reference According to Sakagami & Kuribayashi (1979) and Sakagami et al. (1984), some biological information is available. Nest place and structure: the female prefers to make a nest at the forest edge; the nest structure is the IIIa type of Sakagami & Michener (1962). Social structure and life cycle: the brooding period of the overwintered generation is from early May to late July, in Sapporo city, Hokkaido; most of the overwintering females stay communally in the natal nests; the nest are communally reused in the next brooding season, hence many colonies are semisocial or sometimes delayed eusocial from the beginning of spring activities; females living in the same nests are mostly of the same generation and seem to be sisters in most cases, although some nests are inhabited by a two-year-old female and her daughters; all cohabiting females are inseminated, but only one of them has fully developed ovaries at the peak of brooding season, the others with undeveloped ovaries participate in foraging. : Published as part of Murao, Ryuki, Tadauchi, Osamu & Lee, Heung-Sik, 2015, Synopsis of Lasioglossum (Dialictus) Robertson, 1902 (Hymenoptera, Apoidea, Halictidae) in Japan, the Korean Peninsula and Taiwan, pp. 1-50 in European Journal of Taxonomy 137 on pages 27-32, DOI: 10.5852/ejt.2015.137, http://zenodo.org/record/3785420 : {"references": ["Pesenko Y.

Basal area approximately 2.3 × as wide as long in female, 3 × in male; basal elevation of female moderately developed, that of male absent; distal process of female slender, nearly as long as basal area, and without lateral projection, that of male absent; keel of distal process narrow, apically pointed; labral fimbria acutely pointed at apex in both sexes. STERNA. S4 medially with shallow groove on apical half; apical margin nearly straight. S5 without apical depression, medially weakly swollen and apico-medially cleaved; apical margin gently incurved. S6 normally shaped, not modified. S7–S8 (Fig. 16F): S7 with elongate, apically rounded median process, apex exceeding S8; S8 without median process. MALE GENITALIA (Fig. 16 A–E). Gonobase nearly flat at bottom, ventral arms connected with each other at upper ends; gonocoxite smooth, gently sloped in lateral view, and inner dorsal margin gently angulate at approximately basal 1/3; gonostylus large, located at top of gonocoxite, with dense short setae on inner surface; ventral retrorse lobe moderately long but not reaching gonobase, with dense short setae ventrally and relatively long blunt setae laterally; penis valve higher than gonocoxite, with high cleft on top. Distribution Russian Far East (Sakhalin) and Japan (Hokkaido, northern to central Honshu). Ebmer (1978, 2006) recorded this species from Primorsky and North Korea, respectively, based on female specimens. These records are not included in this paper, because the female cannot be clearly separated from that of some of the related species. Flight period Female: May to September in Hokkaido, Japan. Male: August to October. The flight record of females is based on specimens collected from the eastern part of Hokkaido, Japan. This record can be considered accurate, because one of the related species, L. virideglaucum Ebmer & Sakagami, does not sympatrically inhabit this area. Flower records In Japan this species visits the following 19 species in 6 families: Apiaceae: Angelica ursina (Rupr.) Maxim. Asteraceae: Anaphalis margaritacea (L.) Benth. & Hook. f. subsp. margaritacea Aster glehnii F. Schmidt; Cirsium setosum (Willd.) M. Bieb.; Crepidiastrum denticulatum (Houtt.) J.H. Pak & Kawano; Erigeron annuus (L.)

Krylov; Rudbeckia laciniata L.; Senecio pseudoarnica Less.; Solidago altissima L.; S. virgaurea L. subsp. asiatica (Nakai ex H. Hara) Kitam. ex H. Hara var. asiatica Nakai ex H. Hara; S. virgaulea L. subsp. leiocarpa (Benth.) Hultén; Sonchus brachyotus DC.; Taraxacum sp. Brassicaceae: Barbarea orthoceras Ledeb. Geraniaceae: Geranium thunbergii Siebold ex Lindl. & Paxton. Lamiaceae: Isodon sp. Rosaceae: Sorbaria sorbifolia (L.) A. Braun. Biological reference According to Sakagami & Kuribayashi (1979) and Sakagami et al. (1984), some biological information is available. Nest place and structure: the female prefers to make a nest at the forest edge; the nest structure is the IIIa type of Sakagami & Michener (1962). Social structure and life cycle: the brooding period of the overwintered generation is from early May to late July, in Sapporo city, Hokkaido; most of the overwintering females stay communally in the natal nests; the nest are communally reused in the next brooding season, hence many colonies are semisocial or sometimes delayed eusocial from the beginning of spring activities; females living in the same nests are mostly of the same generation and seem to be sisters in most cases, although some nests are inhabited by a two-year-old female and her daughters; all cohabiting females are inseminated, but only one of them has fully developed ovaries at the peak of brooding season, the others with undeveloped ovaries participate in foraging. : Published as part of Murao, Ryuki, Tadauchi, Osamu & Lee, Heung-Sik, 2015, Synopsis of Lasioglossum (Dialictus) Robertson, 1902 (Hymenoptera, Apoidea, Halictidae) in Japan, the Korean Peninsula and Taiwan, pp. 1-50 in European Journal of Taxonomy 137 on pages 27-32, DOI: 10.5852/ejt.2015.137, http://zenodo.org/record/3785420 : {"references": ["Pesenko Y.
