description: 7. Panurginus kropotkini sp. n.
Diagnosis. The female of Panurginus kropotkini has smooth interspaces on the metasomal terga like at P. niger, which is the most usual species among the bees of the genus in Primorskiy Kray; but metasomal terga of P. kropotkini with pits larger than at P. niger. The female of P. kropotkini is very well recognizable by its clypeus shagreened and with longitudinal grooves; labral plate longitudinally sulcated; propodeal triangle entirely strongly rugose including vertical part.
Etymology. The species is called in memory of Pyotr Alexeyevich Kropotkin (Russian: Петр Алексеевич Кропоткин; 1842–1921), a zoologist, an evolutionary theorist, geographer and one of the world's foremost social philosophers and anarchists. Kropotkin traveled the Amur region and the northern part of Manchuria; he published descriptions of his travels, and materials for the orography of Siberia.
Geographical distribution. Russia, Primorskiy Kray.
Type material. Holotype: Ƥ, RUSSIA, Primorskiy Kray, Barabash-Levada, 44° 52’ 01” N, 134° 47’ 18” E, 20.VII.1982, A. Leley [Приморье, Барабаш-Левада, 20.VII.1982, A. Лелей].
Description. FEMALE. Body length 4.5 mm. Wing yellowish-brown fumigated, with brown veins. Body poorly pubescent; face coarsely, mesosoma and metasoma finely sculptured. Shape. Head transverse (0.8), as wide as mesosoma. Pedicel as long as wide, F1−F3 subequal in length, F1 elongate, F2 and F3 transverse; other flagellomeres as wide as long or longer. Labral plate apically narrowed and rounded, with transverse depression sulcated longitudinally. Facial fovea long and narrow, parallel-sides, apically not enlarged, rounded, as wide as distant to eye; lower end a little closer to eye. Genal area wider than eye (1.25), wide on the most part of its length. Middle basitarsus parallel-sided, 3 times as long as wide, with straight distal margin. Hind basitarsus parallel-sided, 4.5 times as long as wide; TM2 and TM3 elongate, TM4 as long as wide. Metasomal terga with marginal zone depressed, on T1 ca 1/2, T2 and T3 2/3, on T4 as long as discal length; premarginal lines rounded, laterally more abrupt. Sculpture. Antennal scape shiny, with dense punctures. Vertex tessellate, with round pits about a pit diameter apart (10−20 µm / 0.5−2). Paraocular area tessellate, on lower half smoother; upper half with tiny pits about a diameter apart (10−15 µm / 0.5−1), below pits are larger and sparser (15−25 µm / 1−3). Subantennal and supraclypeal areas shiny, tessellate, with dense, deep pits 1−3 diameters apart (ca 10 µm). Clypeus matt, shagreened, with dense, large pits creating longitudinal grooves a diameter or less apart to confluent (15−25 µm / 0.5−1.5). Genal area shiny, delicately tessellate, with pores and pits about a pit diameter apart, below sparser. Scutum on disc shiny, tessellate, on posterior half smoother, with sparse pits and punctures 1 or more diameters apart; on periphery shagreened, with pits small and merged. Scutellum with scattered pits (10−25 µm / 1−4), on periphery smaller and denser; central longitudinal depression with large pits merged. Mesepisternum shagreened, with shallow pits 1−2 diameters apart (15−20 µm / 0.5−3). Propodeum shagreened, laterally with sparse punctures; propodeal triangle rugose entirely, including vertical part. Metasomal terga glossy, laterally and basally tessellate; marginal zones delicately tessellate, impunctate; T1 with punctures a few diameters apart, T2 and T3 discs with punctures and pits 1−2 pit diameters apart (5−15 µm / 1−5), laterally denser; T4 tessellate, punctured sparser than other terga. Metasomal sterna shiny, tessellate, with scattered, small hair pores; discs with short, sparse, tiny hairs; S3 medially with premarginal pores denser and deeper; S4 and S5 shagreened, with dense pores about a pore diameter apart. Coloration. Wing yellowish-brown, with brown veins. Flagellum beneath brown. Claws and spurs yellow. Pygidial plate reddish, apically black. Vestiture. Pubescence white; only pygidial and prepygidial fimbriae, as well as S4 and S5 marginal, dense and long hair fringes are brownish-yellow.
Discussion. Exclusively specific, roughly sculptured clypeus and labral plate at the female, leading to a suggestion that the male of this species should passes some conspicuous morphological characters as well.
