Ammophila formosensis TSUNEKI ( Figs 61 , 157 )

As Ammophila subassimilis TSUNEKI 1967a: 383 (Taiwan) , corrected to Ammophila formosensis by TSUNEKI 1967b: 18 and 1971: 4.

Ammophila formosana TSUNEKI 1967b: 18 , ♀, 3, junior primary homonym of Ammophila formosana STRAND 1913 . Holotype: ♀, Taiwan: Chiayi Prefecture: Fenchihu (originally K. Tsuneki coll., now USNM), examined.

Ammophila formosensis TSUNEKI 1971a: 4 , substitute name for Ammophila formosana TSUNEKI 1967 .

M a t e r i a l e x a m i n e d Holotype ♀ ( USNM); India: Kashmir Khatbatse 3000m (1♀ BMNH).

R e c o g n i t i o n Ammophila formosensis has the gastral apex with a bluish-black metallic shine and the supra-antennal lamellate projection well developed. The female differs from A. infesta in having the clypeus, the frons, the mesopleuron and the propodeum covered with appressed silvery setae and the propodeal enclosure all covered with erect setae ( A. infesta has only the posterior part of the pronotal lobe and the propodeal enclosure medially covered with appressed silvery setae). It differs from A. sabulosa in having a more developed supra-antennal lamellate projection. The male of A. formosensis differs from A. infesta in having the mesopleuron covered with appressed silvery setae ( A. infesta has only a small patch along the mesopleural suture covered with appressed silvery setae), and from A. sabulosa in having the supra-antennal lamellate projection more developed and the mesopleuron covered with distinct appressed silvery setae.

D e s c r i p t i o n: Gastral apex with bluish-black metallic shine, supra-antennal lamellate projection well developed, anterior margin of the mesothoracic venter not

prominent, episternal sulcus extending to anteroventral margin of pleuron, arolia well developed and claws without basal tooth.

♀: 19-22.5 mm. Black except tergum I (except basal third) and gastral segments II and III red (sterna partly darkened). Clypeus (except adjacent to free margin), frons, pronotal lobe, broad band along mesopleural suture and propodeum posterolaterally covered with appressed silvery setae; coxa pruinose, erect setae whitish. Clypeus slightly elongate, with distinct median lobe ( Fig. 61 ), disk convex. Pronotal collar shiny and sparsely punctate ( Fig. 157 ). Scutum medially irregularly, coarsely punctate (punctures 0-1 diameters apart), laterally finely, transversely striate. Scutellum longitudinally ridged and punctate, propodeal enclosure transversely or irregularly ridged and all covered with erect setae. Mesopleuron, metapleuron and propodeum laterally punctato-rugose. Flagellomere I: II=1.4; length of petiole = hindtarsomeres I+0.5×II to I+0.75×II.

3(Tsuneki 1967: 18): 16-20 mm. Black, except tergum I (except basally), gastral segment II and tergum III basally, all these terga carrying black streak not completely filling whole length. Petiole slightly longer than tergum I, in some specimens almost equal to hindtarsomere I+II+III or I+II+0.5×III.

G e o g r a p h i c a l d i s t r i b u t i o n: Taiwan, India (Kashmir).
