Taxonomic note. Warncke identified material belonging to the interrupta group as a new species and labelled it as Anthidium taurica (holotype and paratypes) but did not publish it before he died. This material is deposited in OLL. Dubitzky (2007) examined it and included it in his description of Trachusa heinzi . However, he did not recognise that the remaining material belonged to two undescribed species and attributed it to and labelled it as ‘ Anthidium interruptum ’.

Description. Female: Yellow bands on T1–T2 interrupted medially, separated by a wide gap; band on T3 gradually tapering medially (uninterrupted or interrupted by a narrow gap) ( Fig. 36A View FIGURE 36 ); scutellum with broad yellow anterolateral L-shaped stripe; scutellum and axillae together with four yellow spots ( Fig. 36A View FIGURE 36 ); pronotal lobe black; mid-femur with yellow stripe almost extending to distal end; inner side of hind tibia black.

Male: Antenna long, average length of Sg4–Sg6 between 0.47 and 0.54 mm ( Fig. 38 View FIGURE 38 ); yellow bands on T1–T2 interrupted, others uninterrupted ( Fig. 36C View FIGURE 36 ); scutum black or black with some remnants of a lateral stripe near tegula ( Fig. 36C View FIGURE 36 ); inner side of hind tibia black.

Differential Diagnosis. The species is characterised by relatively long antennae, somewhat longer than in T. heinzi , but significantly longer than in T. integra and T. anatolica and significantly shorter than in T. grandicornis ( Fig. 38 View FIGURE 38 ). In addition to antennal length, the male is distinguished from T. grandicornis by the interrupted yellow band on T2 (Type D or E in Fig. 1 View FIGURE 1 ), which is never interrupted in T. grandicornis (Type C). Trachusa heinzi has, among other features, a pronotal projection (absent in T. taurica ) and the band on T2 which is uninterrupted or the lateral bands are contiguous (Type C or D).

The female shares with T. grandicornis and T. anatolica the dark pronotal lobes, which are yellow in T. heinzi . The inner hind tibiae have black maculations (as in T. heinzi and T. grandicornis , but such maculation is normally absent in T. anatolica ). The genae have rich yellow colouration in T. heinzi , T. anatolica and T. grandicornis , while it is confined to a relatively small spot in T. taurica and T. interrupta .

The female of T. taurica has a yellow stripe on the mid-femora which extends over almost the entire femur lengths and the inner sides of the hind tibiae are black, while in most T. interrupta , the mid-femora have only small yellow maculation and the inner hind tibiae are entirely yellow. However, these characters do not always hold true, but the widely separated distribution areas may be used for species attribution.

In the morphometric DFA ( Fig. 14 View FIGURE 14 ), males of T. taurica form a cluster very close to T. heinzi , a species which is, however, otherwise well distinguished by other morphological and colouration features. The three species T. grandicornis , T. taurica and T. heinzi form by their long antennae a group of long-horned species. The confusion matrix ( Table 4 View TABLE 4 ) shows that 90.91% of all males and only 50.0% of the females are correctly attributed. Females are thus morphologically less differentiated.

Derivatio nominis. The name refers to the Taurus Mountains which forms the northern boundary of the species’ distribution. The name was coined by K. Warncke and used on various labels, although the name was also attached to specimens which have been attributed to T. heinzi and T. grandicornis . Klaus Warncke passed away before he could publish a description of taurica .

Distribution. The distribution area is confined to the eastern Mediterranean region of Turkey including the Turkish-Syrian border area. It is found in the Turkish provinces of Kahramanmaraş, Mersin, Adana, and Antalya and in Syria or the Hatay province of Turkey.
