(Figs 2–3) belongs to the Milesia crabroniformis species group (see Remarks below), of which M. crabroniformis hitherto was the only member (Hippa 1990). It differs from M. crabroniformis (Fig. 4) as follows: vertex blackish caused by less dense pollinosity, completely yellow in M. crabroniformis; female frons medially with indistinct brown longitudinal vitta caused by the absence of pollinosity, completely yellow in M. crabroniformis; ground colour of the scutum is black except for a small rectangular orange brown part between the postalar calli, in M. crabroniformis the orange brown ground colour is much more extensive forming longitudinal vitta on the posterior part of the scutum; scutum with heavy yellow pollinose pattern on both anterior and posterior part of scutum, in M. crabroniformis the yellow pollinosity is less extensive on the posterior part, making the orange brown ground colour pattern visible, creating a colour contrast between the yellow pollinose pattern on the anterior part and an orange brown ground colour pattern on the posterior part; on the medial part of the scutum two short yellow pollinose vittae depart as part of the anterior vittae into the posterior part, in M. crabroniformis these yellow pollinose vittae are absent; the anterior half of the scutellum is black, in M. crabroniformis the scutellum is usually all red or only with a small anterior portion black, anterior half seldom black; scutellum completely yellow pilose, at least one or a few black pili present in M. crabroniformis; in the male, pleura, coxae and trochanters largely black, on average with more yellow markings in M. crabroniformis. Legs are more extensively black marked but less extensively black pilose in Milesia cretica sp. nov.; metatibia medially with black markings and ventrally covered with black pile for some 25% of the length of the tibia in the male, in M. crabroniformis no black markings are present on metatibia, but black pile is more extensive, covering at least 40% of the length of the tibia; in the female, the metatibia is covered with black pile for some 10% of the length of the tibia, at least 30% in M. crabroniformis. Milesia cretica sp. nov. has the anterior half of the wing not clearly yellowish tinged and without subtle darker greyish subapical macula, the former character (clearly yellowish tinged) always present and the latter (subtle darker greyish subapical macula) usually present in M. crabroniformis. Terga 2–4 yellow and dark yellow with sharply demarcated black pattern in the new species, in M. crabroniformis colour pattern rather diffuse, extending from yellow to dark brown, without sharply demarcated black pattern. No diagnosable differences in male genitalia between the two species could be detected (Fig. 7).</p> <p>Etymology</p> <p>The species name is from the Latin ‘ creticus, cretica ’, meaning ‘Cretan’ and it refers to the type locality of this Milesia, the island of Crete.</p> <p>Type material</p> <p>Holotype GREECE • ♂; Crete, Chania, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=24.162806&amp;materialsCitation.latitude=35.232613" title="Search Plazi for locations around (long 24.162806/lat 35.232613)">Imbros Gorge</a>; 35°13′57.4″ N, 24°09′46.1″ E; alt. 554 m; 8 Oct. 2021; S.

The localities of the H. helix differed, ranging from dry river beds with old Platanus trees to gardens, gorges and edges of groves. A female was flushed from a deep crevice with decaying wood at 0.5 m height in a Platanus orientalis L. Afterwards, it hovered some time with its extended ovipositor curled under de abdomen in front of this crevice before flying off. A male was seen hovering around a Castanea sativa Mill. tree as if it were defending a territory. This suggests that M. cretica sp. nov. uses P. orientalis and possibly also C. sativa as its breeding habitat.</p> <p>Distribution</p> <p>The species is only known from the island of Crete, Greece and is presumed to be a Cretan endemic. During the field work, Milesia cretica sp. nov. was collected from seven locations; all specimens were collected by hand with an entomological net. On the website iNaturalist under catalogue number 67354454 another observation was found: https://www.inaturalist.org/observations/67354454. All known localities are visualized in Figure 1.</p> <p>DNA barcode analysis</p> <p>A total of 54 COI sequences for different species of Milesia were analysed, including our five sequences of M. cretica sp. nov. (Fig. 9). The NJ tree depicts well-defined, genetically divergent clusters that reflect morphological species with high bootstrap support values (BS&gt; 92). Our analysis recovered the Milesia crabroniformis group (BS = 99.5), our new species (BS = 100) and M. crabroniformis (BS = 100) with high support.</p> <p>From the newly obtained COI sequences for M. cretica sp. nov., the sequence ON059134 (paratype ZFMK-DIP-00083002) differs 0.152% from the other four sequences, which are identical. COI barcodes of M. cretica sp. nov. differ more than 2% from the sequences of M. crabroniformis (2.13–2.66%), while the intraspecific variability in the latter taxon is less than 1% (0.0–0.68%) among the studied European specimens. In general, the intraspecific divergence among the COI sequences from the studied species is always lower than 1%, except for M. virginiensis (Drury, 1773) whose COI sequences differ 0.46– 1.52%.</p> <p>Remarks</p> <p>In overall appearance, M. cretica sp. nov. is remarkably similar to the Nearctic species Milesia virginiensis (Fig. 6), sharing the black and yellow pattern on terga 2, 3 and 4. This is unexpected since M. virginiensis occurs in a different realm and belongs to a different species group (Hippa 1990). The Milesia crabroniformis group differs from the Milesia virginiensis group by, for example, slightly tuberculate face; alula and cell r completely microtrichose; profemur with flattened basoventral area; and male genitalia very different (Hippa 1990).</p> <p>Milesia cretica sp. nov. belongs to the crabroniformis species group as defined by Hippa (1990). The following morphological characters are shared by M. cretica sp. nov. with the crabroniformis species group: bare anterior anepisternum; bare pleura at ventral end of posterior spiracle; face not strongly produced; proboscis normal and with short labella; cell r 1 closed; alula and posterior part of cell br completely microtrichose; posterior spiracle open only on dorsal part; male profemur with a wide basoventral depressed area; and female abdominal tergum 5 medially submembranous and laterally compressed. Still, M. cretica sp. nov. does not key satisfactorily to any of the species groups in Hippa’s (1990) key. This is because it has a partly black vertex and partly black terga compared to M. crabroniformis, and thus, not all characters univocally key out to the M. crabroniformis group in couplets 15 and 16. When disregarding the colouration, but maintaining the structural characters, M. cretica sp. nov. keys out in the M. crabroniformis species group in Hippa’s (1990) key:</p> <p>15.
