Ammophila modesta MOCSÁRY ( Figs 59 , 93 , 153 , 230 , 353 , 414 , 476 , 534 )

Ammophila modesta MOCSÁRY 1883: 28 , ♀. Holotype: ♀, Spain: Granada (TMB), examined.

M a t e r i a l e x a m i n e d: Holotype ♀ ( TMB), 4♀♀, 1533 ( OÖLM), 233 ( NHMW).

R e c o g n i t i o n Ammophila modesta has the gastral apex black without metallic shine, the pronotal collar not transversely striate, the episternal sulcus extending to the anteroventral margin of the pleuron and the mesothoracic venter not prominent anteriorly. Additionally, the supra-antennal lamellate projection is absent, and the propodeal enclosure is all covered with erect setae. The clypeus, the frons, the pronotal lobe, a broad band along mesopleural suture and the propodeum posterolaterally are covered with appressed silvery setae. The petiole is black. Both sexes of A. terminata differ from A. modesta in having a glabrous propodeal enclosure and the gastral apex with metallic shine. The female of A. sabulosa differs from A. modesta in having no appressed silvery setae on the clypeus and the frons and a blue-black gastral apex with metallic shine. Both sexes of A. assimilis differ from A. modesta in having the pronotal collar dorsally smooth and shiny, with coarse, sparse punctures and a shiny scutum, coarsely punctate and laterally transversely striate ( A. modesta has the pronotal collar dorsally dull and coriaceous, and the scutum is dull, coriaceous and transversely microstriate). Both sexes of A. mitlaensis differ from A. modesta only in having a red petiole. The male of A. sabulosa differs from A. modesta in having the gastral apex with metallic shine and the mesopleuron without a distinct patch of appressed silvery setae.

D e s c r i p t i o n: Gastral apex black, without metallic shine, pronotal collar not transversely striate, episternal sulcus extending to anteroventral margin of pleuron and mesothoracic venter not prominent anteriorly. Supra-antennal lamellate projection absent, arolia distinct developed and claws without basal tooth.

♀: 15-19.5 mm. Black except tergum I and gastral segments II-IV red; in some specimens tergum I basally and tergum IV dorsally black. Clypeus, frons, pronotal lobe, broad band along mesopleural suture, propodeum posterolaterally and coxa covered with appressed silvery setae; erect setae whitish-grey. Clypeus slightly elongate ( Fig. 59 ), disk convex ( Fig. 93 ). Pronotal collar dorsally dull and coriaceous, scutum dull, coriaceous, sparsely punctate and transversely microstriate, scutellum longitudinally striate. Propodeal enclosure coarsely obliquely punctato-rugose and covered with erect setae, mesopleuron coriaceous and punctate. Pronotal collar laterally: Fig. 153 . Flagellomere I: II=1.5-1.8; length of petiole = hindtarsomeres I+0.5× II to I+0.75×II.

3: 13-19 mm. Black, except tergum I and gastral segments II-IV (V) red, all with black dorsal stripe. Clypeus, frons, pronotal lobe, mesopleuron and propodeum posterolaterally covered with appressed silvery setae; in most specimens pronotal collar, scutum and coxa covered with fine, short appressed silvery setae; erect setae whitish-grey. Clypeus elongate, narrowed and distinctly emarginate ( Fig. 230 ), disk nearly flat ( Fig. 353 ). Pronotal collar dorsally dull, coriaceous and sparsely punctate, scutum dull, coriaceous, punctate and transversely microstriate, scutellum coarsely longitudinally punctatorugose. Propodeal enclosure obliquely punctato-rugose, covered with erect setae and mesopleuron coriaceous and coarsely punctate (punctures 0-1 diameter apart). Gonostyle laterally: Fig. 414 ; penis valve laterally: Fig. 476 , ventrally: Fig. 534 . Flagellomere I: II=1.5-1.6; length of petiole = hindtarsomeres I+II to I+II+0.3×III.
