Merodon defectus Vujic, Likov & Radenkovic sp. nov. Figs 12J, K View Figure 12 , 13E View Figure 13 , 14A, B, D View Figure 14 , 15B View Figure 15 , 16C View Figure 16
Diagnosis.
Medium sized (7.6-10.9 mm), dark species with olive-brown reflection; antennae dark brown; legs mostly black; basoflagellomere elongated (in males 1.8 times as long as wide) obviously concave dorsally; arista short, 1.6-1.8 times as long as basoflagellomere (Fig. 12J, K View Figure 12 ); terga dark brown to black, except pale yellow-orange lateral maculae on tergum 2; metafemur incrassate, ventrally covered with pilosity of medium length (Fig. 13E View Figure 13 ); male genitalia: posterior surstyle lobe with very small lateral hump (Fig. 14A, B View Figure 14 : bp); apical part of anterior surstyle lobe triangular (Fig. 14A View Figure 14 : al); lingula medium sized (Fig. 14D View Figure 14 : l). Similar to Merodon serrulatus from which differs in reduced lateral hump on posterior surstyle lobe (Fig. 14A, B View Figure 14 : bp) (in M. serrulatus distinct, Fig. 1A, B View Figure 1 : bp, 14C: bp). Morphologically related to M. opacus sp. nov. and M. hirsutus from which can be distinguished by the presence of yellow-orange lateral maculae on tergum 2 (in M. opacus sp. nov. and M. hirsutus tergum 2 dark). Additionally, differing from M. hirsutus by shorter dorsolateral pile on metafemur (Fig. 13E View Figure 13 ) and posterior surstyle lobe with very small lateral hump (Fig. 14A, B View Figure 14 : bp), well developed in M. hirsutus (Fig. 14E, F View Figure 14 : bp) and M. opacus sp. nov. (14H, I: bp).
Description.
Male. Head. Antennae black to dark brown; basoflagellomere elongated, 1.8 times as long as wide, and 2.3 times as long as pedicel, concave dorsally with acute apex; dorsolateral fossette large; arista dark brown and thickened at basal one third, covered with dense microtrichia, 1.6-1.8 times as long as basoflagellomere (Fig. 12J View Figure 12 ); face black with gray microtrichia, covered with whitish pile; oral margin microtrichose, with small, shiny, lateral bare area; lunule shiny black; frons microtrichose, with yellowish gray pile; eye contiguity ca. eight facets long; vertex isosceles, with long, pale whitish yellow pile, mixed with black pile on the ocellar triangle; ocellar triangle isosceles (Fig. 16C View Figure 16 ); occiput shiny, with gray-yellow pile; eyes covered with dense pile; vertical triangle: eye contiguity: frons = 3: 1: 3.
Thorax. Scutum and scutellum black with bronze luster, covered with dense, erect, yellow pile; scutum at wing basis with short black pile and some black pile between wing basis, from few ones to fascia of black pilosity in some specimens; scutum usually 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 yellowish; halteres brown-yellow; legs mostly black, except brown tarsi ventrally in some specimens; pile on legs gray-yellow; metafemur moderately incrassate, ca. three times longer than wide; pile on postero- and anteroventral surface of medium length; pile on dorsolateral surface dense and length ca. one third to one fourth of width of metafemur (Fig. 13E View Figure 13 ).
Abdomen. Tapering, 1.2 times longer than mesonotum; terga dark brown to black, except pale yellow-orange lateral maculae on tergum 2; terga 2-4 each with a pair of white microtrichose, oblique fasciae (on tergum 2 triangular); pile on terga long, yellow, except some black pile on terga 3 and 4 medially; sterna dark brown, covered with long whitish yellow pile.
Male genitalia. Apical part of anterior surstyle lobe triangular, ca. two times longer than wide, covered with dense, short pile (Fig. 14A View Figure 14 : al); posterior surstyle lobe with very small basolateral protrusion (Fig. 14A, B View Figure 14 : bp); hypandrium sickle-shaped, without lateral projections; lingula medium size (Fig. 14D View Figure 14 : l).
Female. Similar to the male except for normal sexual dimorphism and for the following characteristics: basoflagellomere ca. two times longer than wide (Fig. 12K View Figure 12 ), fossette dorsal; frons with broad microtrichose vittae along eye margins; frons covered with pilosity of variable color, from mostly gray-yellow to predominantly black; ocellar triangle covered with black pile; terga with whitish pile, except terga 2-5 medially with short black pile; microtrichose fasciae on terga 3 and 4 conspicuous (Fig. 15C View Figure 15 ).
Etymology.
Latin adjective defectus (reduced in size, smaller) refers to small basolateral protrusion (lateral hump) on posterior surstyle lobe.
Distribution.
Merodon defectus sp. nov. has been identified in western Turkey (Fig. 7 View Figure 7 ).
Ecology.
Preferred environment: forest/open ground; thermophilous and evergreen Quercus forest; Castanea forest, dry Pinus forest; unimproved grassland and tracksides; coniferous forest with some yellow flowers along a stream [ Reemer and Smit (2007) refer to this last observation as being Merodon alexeji Paramonov, 1925]. Flowers visited: Ornithogalum spp., Potentilla spp., and Thymus spp. Flight period: May-July.
