Colletes inspersus; Ascher & Pickering 2021. Diagnosis. The female of C. inspersus (the male remains unknown) may be diagnosed through the following combination of features: bees relatively small (HW 2.6–2.7 mm), T1 finely and very sparsely (i=2.0–3.0 d) punctate medially and T2 without basal. Females of C. inspersus are similar to those of both C. xuezhongi and C. xizangensis, from which they can be differentiated by the paraocular area with pale-yellow and black hairs intermixed (paraocular area with only pale hairs in females of C. xuezhongi and C. xizangensis). Colletes inspersus can be further distinguished from C. xuezhongi by the clypeus longer than broad (clypeus broader than long in females of C. xuezhongi) and from C. xizangensis by the T1 with a broadly interrupted apical band (T1 apical band complete in females of C. xizangensis).

Colletes yanruae Niu, Zhu & Kuhlmann, In 2013
No full textColletes yanruae Niu, Zhu & Kuhlmann, 2013 (Figs 2–11) Colletes yanruae Niu, Zhu & Kuhlmann, In: Niu et al., 2013b: 114 (female). Diagnosis. Like the female, the male C. yanruae has narrow apical tergal hair bands (Figs 6–7) and much long hair on the scutum (Fig. 5). The male has a very large and broad S7 (Figs 10–11) that is similar in shape to that of C. reinigi Noskiewicz, C. luzhouensis Kuhlmann and C. linzhiensis Niu, Zhu & Kuhlmann. But C. yanruae differs from C. reinigi by the finer and denser punctation of terga, the rounded outer apical corners of S7 (shallowly incised in C. reinigi) and the rounded gonostylus (pointed in C. reinigi), and from C. linzhiensis by the distinctly narrower apical tergal hair bands and shorter malar area (Fig. 4). In C. yanruae , the gonostylus is broader than long, while it is narrower at its base and, thus, longer than broad in C. luzhouensis (Fig. 9). The males of both species are otherwise very similar, with only subtle differences in tergal punctation (punctures of T2 only slightly smaller than on T 1 in C. luzhouensis while in C. yanruae punctures of T2 are about half the diameter of those on T1). The male of C. brumalis Noskiewicz is unknown but likely has distinctly broader apical tergal hair bands than C. yanruae, for the female of C. brumalis Noskiewicz with broader apical tergal hair bands than C. yanruae. Description. Male, BL= 9.5 mm (Fig. 2); head broader than long (Fig. 3), HW: HL= 53: 44; gena slightly narrower than eye in lateral view, GW: EW = 9: 12 (Fig. 4); width of metasoma as broad as that between tegulae, MtW: TW = 52: 52. Clypeus slightly convex, median part with fine oblique spine-shaped punctation (Fig. 3); antenna short, extending to the middle of scutellum, first flagellomere slightly longer than broad, 0.7 time as long as second flagellomere, flagellomeres 2–11 longer than broad, nearly 1.5 times as long as broad and nearly equal to each other in length; malar area medially shorter than width of mandible base, about 1/2 long as width of mandible base; facial fovea shallow and narrow, only half as wide as antennal flagellum; vertex behind eye rounded; propodeum laterally covered with sparse long erect hairs, integumental sculpture completely visible; disc of scutum shiny, with dense punctation, i = 0.5–1.5d (Fig. 5); metasomal terga with apical hair bands, the band on T1 slightly narrower medially, that on T2–T5 nearly 1/6 width as that of the related exposed terga (Fig. 6); posterior margin of T1 translucent and orange, punctation on disc of T1 round and dense, i = 0.2–0.5d (Fig. 7); sloping anterior and lateral anterior parts of T1 covered with erect long plumose hairs, and disc of T1 also with erect long sparse plumose hairs (Fig. 7); apical lobe of S7 large and broad, outer apical corner rounded, but with inside concave below the apical corner (Fig. 10); genitalia as showing in Fig. 8 and Fig. 9, gonostylus short and broad at its base. Antennal flagellum ventrally black; all legs black. Face covered with dense long paler white plumose hairs, intermixed with black plumose hairs; gena, scutellum and mesepisternum covered with long paler white plumose hairs; scutum covered with dense long paler white plumose hairs, intermixed with black plumose hairs (Figs 4–5).

Colletes xuezhongi; Ascher & Pickering 2021. Diagnosis. The female of C. xuezhongi (the male remains unknown) is recognizable through the following combination of features: bees relatively small (HW 2.7–2.8 mm), clypeus relatively sparsely punctate (i=1.0–2.0 complete apical band in the latter) and the T2 has a distinct basal band (T2 without basal band in the latter). Females of C. xuezhongi are also similar to those of C. inspersus, but they can be differentiated by the malar area 0.75× as long as basal width of mandible in the former (malar area 1.0× as long as basal width of mandible in the latter) and the paraocular area with only pale-yellow hairs in the former (paraocular area with pale-yellow and black hairs intermixed in the latter).

Remarks. The new species is somewhat similar to S. metallica, but differs from the latter by the following: the apical 2 / 3 of forewing distinctly infuscated; the hairs on dorsum of head curved, 2 × transverse diameter of median ocellus; postocellar area without middle carina; mesoscutellum with a peak; 4 th and 5 th hind tarsomeres yellowish white; punctures on metapleuron shallow and fine; the upper margin of supraantennal tubercle elevated; valvicep of penis valve oval. In S. metallica: the apical 2 / 3 of forewing indistinctly infuscated; the hairs on dorsum of head nearly straight, equal to transverse diameter of median ocellus; postocellar area with a distinct middle longitudinal carina; mesoscutellum without peak; hind tarsi entirely blue; punctures on metapleuron dense and coarse; the upper margin of supraantennal tubercle obtuse; valvicep of penis valve narrow.

Lasioglossum (Dialictus) submandibulare Niu 2020, sp. nov.
No full text<i>Lasioglossum</i> (<i>Dialictus</i>) <i>submandibulare</i> Niu, sp. nov. (Figs 4–5) <p>Type material. Holotype, female, China, Sichuan, Mao Xian (31º43′N, 103º55′E), 25.V.2011, leg. Zeqing Niu.</p> <p> Etymology. The specific name means the new species is very similar to <i>Lasioglossum mandibulare</i> (Morawitz, 1866).</p> <p> Diagnosis. According to the current subgeneric classification of the genus <i>Lasioglossum</i> (Gibbs, 2010), the new species belongs to the subgenus <i>Dialictus</i>. The extraordinary and amazing characters of the new species is its elongated mandible (Fig. 4C) and strongly raised pronotum (Fig. 4G). The new species is very similar to <i>L. mandibulare</i> (Morawitz, 1866) by its elongated mandible. Comparing with the type species of <i>L. mandibulare</i> (Morawitz, 1866) (Astafurova & Proshchalykin, 2018), the species has following characters: head and mesosoma with blue-green metallic reflections; antennal flagellum blackish-brown (Fig. 4A); mandible dark brown (Fig. 4C); all tibiae and tarsi brown (Fig. 5A); punctures on clypeus and supraclypeal area sparser; the dorsolateral angle of pronotum triangle, right-angle apically (Fig. 4D); lateral slope of propodeum smooth, without fine striate (Fig. 4E). Meanwhile, <i>L. mandibulare</i> (Morawitz, 1866) is characterized by: head and mesosoma black, without metallic reflections; antennal flagellum yellowish-brown; mandible yellow; all tarsi yellowishbrown; lateral slope of propodeum with fine striae.</p> <p> The new species is also similar to <i>L. pronotale</i> Ebmer, 2002 by the strongly raised pronotum, but has the head as broad as long, nearly quadrate in frontal view, while the head of <i>L. pronotale</i> is longer than broad, longitudinal rectangular in frontal view.</p> <p>Description. Female. BL 7.0 mm (Fig. 5A); head quadrate in frontal view, nearly as broad as long, HW: HL = 48: 47 (Fig. 5B); vertex long, ocelloccipital distance long, about 4 times as long as the lateral ocellus diameter (Fig. 4A); gena obviously broader than eye, GW: EW = 19: 9 (Fig. 4B). Clypeus rectangle, nearly 3 times as broad as long, apical margin truncate (Fig. 4C); mandible elongate, with single preapical tooth (Fig. 4C); forewing with three submarginal cells, 1st equal in length to 2nd and 3rd combined, distal veins (1rs-m, 2rs-m, 2m-cu and distal abscissae of M) weak, marginal cell pointed on anterior margin of wing (Fig. 5B); dorsolateral angle of pronotum triangle, right-angle shaped apically (Fig. 4D), pronotum strongly convex toward to the dorsum (Fig. 4G); propodeal dorsum as long as scutellum, nearly flat, with very fine striae not reaching posterior margin of propodeal dorsum (Fig. 4E); lateral slope of propodeum smooth, without fine striae (Fig. 4E), posterior vertical surface of propodeum carinate along lateral margin, but the carina ill-developed, only up to 2/3 of the lateral margin, lateral carina and transverse carina absent (Fig. 4E); hind basitibial plate present, enclosed by carina; inner hind tibial spur pectinate with two large teeth (Fig. 4H). Clypeus nearly polished, only with a few scattered punctures (Fig. 4C); supraclypeal area very sparsely punctate, i=3–5d (Fig. 4C); paraocular area and frons very densely and finely punctate, i=0.2–1.0d (Fig. 4C); vertex very sparsely punctate, i=5–6d (Fig. 4A); scutellum sparsely punctate, i=1–3d (Fig. 4D); T 1 polished, without punctures (Fig. 4F). Head, mesosoma with blue-green metallic reflections, metasomal terga dull reddish-brown, without metallic reflections (Figs 4F, 5A); mandible dull reddish-brown (Fig. 4C); antenna blackishbrown except flagellum with ventral surface lighter, brown (Fig. 4A); forewing subhyaline with brownish-yellow veins and stigma except R vein brown (Fig. 5B); legs dark brown (Figs 4H, 5A). Clypeus, lower part of paraocular area, vertex, and mesosoma covered sparse dirty-yellowish pubescence. T 2– T 3 with basal whitish tomentum (Fig. 4F). Hind femur and tibia with yellowish plumose hairs forming the scopa (Fig. 4H).</p> <p>Male. Unknown.</p> <p>Distribution. China (Sichuan).</p> <p>Floral association.
