Merodon sacki (Paramonov, 1936) View in CoL Figs 8C View Figure 8 , 9D-F View Figure 9 , 10C, D View Figure 10 , 11D-F View Figure 11
Diagnosis.
Large (9.5-11.6 mm) dark brown species with lack of microtrichose fasciae on terga 2-4 in males (Fig. 10C View Figure 10 ) and curved and very incrassate metafemur with long pile on ventral margin; the longest pile as long as half of width of metafemur (Fig. 8C View Figure 8 ). Similar to Merodon bequaerti but differs by strongly curved metafemur and generally longer body pile, clearly visible on tergum 4 (Fig. 10D View Figure 10 ).
Redescription
(based on holotype and additional material from the type area, Spain). Male. Head. Antennae black to dark brown; basoflagellomere ca. two times as long as wide, and ca. two times as long as pedicel, concave dorsally; large fossette dorsolateral; arista dark and thickened at basal one third, covered with dense microtrichia, 1.6 times as long as basoflagellomere (Fig. 11D-F View Figure 11 ); face and frons black with gray microtrichia, face covered with dense whitish gray, and frons with yellowish gray pile; oral margin microtrichose with shiny lateral areas; lunule shiny black, bare; vertex covered with golden microtrichia around ocellar triangle; vertex isosceles, with long, pale whitish yellow pile mixed with black pile on the ocellar triangle; ocellar triangle equilateral; eyes covered with dense pile; occiput with gray-yellow pile, covered with a dense, gray microtrichia; eye contiguity 10-14 facets long.
Thorax. Scutum and scutellum black with bronze luster, covered with dense, erect, yellow pile; scutum at wing basis with short black pile; scutum with two or more microtrichose vittae, anteriorly connected and posteriorly reaching the scutellum; scutum dull; posterodorsal part of anterior anepisternum, posterior anepisternum (except anteroventral angle), anterior anepimeron, dorsomedial anepimeron, and posterodorsal and anteroventral parts of katepisternum with long, pale yellow pile and grayish microtrichia; wings entirely covered with microtrichia; wing veins brown; calypteres and halteres pale yellowish; legs mostly black, except brown tarsi ventrally in some specimens; pile on legs pale yellow, except black pile at apical one fourth of metafemur; metafemur curved and incrassate, approximately three to four times longer than wide; pile on postero- and anteroventral surface long, and ca. half of width of metafemur (Fig. 8C View Figure 8 ).
Abdomen. Broad, tapering, 1.2 times longer than mesonotum; terga dark brown to black, usually without microtrichose fasciae; tergum 2 with orange lateral maculae; pile on terga all yellow (Fig. 10C, D View Figure 10 ); sterna dark brown, covered with long whitish yellow pile.
Male genitalia. Apical part of anterior surstyle lobe rhomboid in shape, 1.5 times longer than wide, covered with dense, short pile (Fig. 9D View Figure 9 : al); posterior surstyle lobe oval with basolateral protrusion (lateral hump) (Fig. 9D, E View Figure 9 : bp); hypandrium sickle-shaped, without lateral projections; lingula large (Fig. 9F View Figure 9 : l).
Female. Unknown.
Distribution.
Merodon sacki is known only from Spain (Fig. 7 View Figure 7 ).
Ecology.
Preferred environment: forest/open ground; open areas in evergreen oak forest ( Quercus ilex and Q. suber ) and Mediterranean scrub. Flowers visited: no data. Flight period: April-July.
Type material.
Holotype (original designation): male, "Holotypus Lampetia / sacki Paramononv, 1936 / G.V. POPOV des. 2007" [red label], " Lampetia / sacki n. sp. / ♂ Typus / Paramonov d. " [pink label handwritten], " Merodon / mir únbekannt " [yellow label handwritten], " 14 VII 81 " " Chiclana " [handwritten on the back side] (SIZK) (See Supplementary file 6: Figure 6B View Figure 6 ) (studied).
Note (Popov pers. comm.). The species was described by examining a single male, with the type clearly indicated on the label by Paramonov (discovered and deposited in SIZK). The type specimen is considered lost ( Liepa 1969). Hurkmans (1993: 178, 179) incorrectly considered M. sacki as a junior synonym of M. clavipes (Fabricius, 1781). Hurkmans (1993) also provided an incorrect year for the description of Lampetia sacki (1937 instead of the correct 1936), and also incorrectly designated the lectotype and paralectotype [Articles 73 and 74 of the ICZN (1999)] for two M. clavipes females with the same label “Chiklana”, which are not syntypes [a violation of Articles 74.1 and 74.2 of ICZN (1999)]. The holotype was established by the original designation according to Article 73.1.1 of the ICZN (1999), as well as by a monotype according to Article 73.1.2 (ibid.).
