Face covered with coarse contiguous punctation, without discrete polished medial stripe or medial zone of cross-ridging, without silver pubescence and without frontal carina; male (and sometimes female) frons with two large ovoid, flattened or somewhat concave striate areas; malar space short, less than l MOD; mandible with single broad subapical tooth; tongue long; F-I length between two and three times breadth; pronotal anterior declivity with four pits, lateral depression shallow and obsolescent; mesopleuron without episternal sulcus, scrobal sulcus large and deep, subtended by large projecting U-shaped carina; fore wing Rs long but bending slightly away from costal margin, leaving marginal cell broadly open; T-III with slight prepit swelling, pits small, subequal to punctures in size; female T-V with two apical lobes and several coarse apicolateral ridges; S-V with two large apical hooks or lobes; T-VI with sharp medial tooth.
Hemipterochilus bembeciformis (Morawitz) (Eumenidae) has been reported as the host of dallatorreana (=insignis) (Linsenmaier 1959a).
Spinolia is distributed throughout Europe, Africa north of the Sahara, and in the Middle East. However, the centre of diversity is in the southern USSR.
The most distinctive features of Spinolia are the U-shaped projection on the lower mesopleuron, finely denticulate to dentate margin of T-III, dentate ovipositor segments, and the frons with two large round, flattened and usually striate areas; particularly in males. These characteristics immediately separate Spinolia from its closest relatives, Euchroeus and Pseudochrysis. Most Spinolia have the apical margin of T-III finely denticulate or crenulate, but stchurovskyi has multiple, large, irregular teeth. As in Pseudochrysis, the basic colour pattern is a dark blue to purple, as exemplified by algira. However, bright markings on the thoracic dorsum are common, and useful for distinguishing species. In dournovi the vertex and the entire dorsum of the thorax are coppery. In insignis the pronotum, scutum, and scutellum are coppery except for the area between the notauli. A similar pattern occurs in lamprosoma, although the markings are bright green and the scutum is dark except for green bands along the notauli. Spinolia stchurwskyi is quite differently coloured, the body is basically magenta or reddish purple, with bright green tints on the thorax. This genus was reviewed for Europe by Linsenmaier (1959a).
