Diagnosis. Light to dark brown-colored moth with dark crenated medial lines, average wingspan 85 mm in males and 100 mm in females. The second lasiocampid species in size after P. hausmanni sp. nov. within the Palaearctic realm, externally more contrasty and does not fly in Iran. Male genitalia accordingly smaller, phallobase medially less swollen and bent. Antevaginal plate in female genitalia about 3 times smaller.

External variability ( Figs 1–22 View Figures 1–8 View Figures 9–14 View Figures 15–22 ). Dark brown speckles on male forewing vary from sparse to very dense, hindwing color from creamy to brown. Female forewing from creamy with dense brown speckles to brown, hindwing more or less dark with more or pronounced dark external field.

Distribution ( Fig. 37 View Figures 35–37 ). Europe: Sicily and the Italian Peninsula, the Balkans along the Adriatic, Ionian, Aegean, and Mediterranean seas; Asia: from Western Turkey eastwards to Georgia and southwards through the Levant; Africa: South Egypt. In Egypt and Western Saudi Arabia all records are from urban environments, the species was most likely introduced with ornamental pine trees. It is not clear if they will survive over the long run.

Taxonomic note. 1. Drury figured and described P. otus in the first volume of Illustrations of natural history (1770: 30–31, plate XVI, fig. III), but he did not provide the name of the species. The name appeared in the index of the first volume which “was not published until 1773” ( Hemming, 1958). Therefore, 1773 is considered the year of the original description instead of 1770.

2. Zolotuhin and Gurkovich (2009: 7) mentioned the “brighter sandy- yellow” coloration of P. otus fulvescens which is a mistake. Kotzsch (1932) wrote that adults of P. otus fulvescens are “[...] not only much larger than the Dalmatian form in both sexes, but also have much darker forewings and with a reddish sheen of the hindwings [...]” (“In einer grossen Ausbeute aus Syrien (Akbés) erhielt ich unter anderem eine Anzahl Pachypasa otus Dru. , welche nicht nur in beiden Geschlechtern viel grösser als die Dalmatiner Form sind, sondern auch viel dunklere Vorderflügel haben und mit rötlichem Schein der Hinterflügel; dem Thorax fehlt die übliche Aufhellung. Ich schlage für diese Form den Namen fulvescens vor.”) Indeed, most European and Balkan male adults in collections are light creamy-colored ( Figs 2, 4, 6 View Figures 1–8 and 9 View Figures 9–14 from the type locality of P. otus ) – this is the “Dalmatian form” sensu Kotzsch – and some males from Syria and surrounding countries are bigger and darker – that is the form fulvescens ( Fig. 20 View Figures 15–22 ). Although, pale, dark and intermediately colored adults occur sympatrically in various locations ( Figs 9–14 View Figures 9–14 ). Mediocaudal outgrowth of cubile (sensu Lajonquière, 1968; Fig. 28 View Figures 28–33 , shown with arrow) also vary in size from very short to slightly elongated cshaped and does not correlate with wing coloration or collecting locality ( Figs 28–32 View Figures 28–33 ). Average pairwise distance in COI between three European (one Croatian, LBEOW1513-11 and two Greek, PHLAJ071-13 and RONOC087-16) and one Lebanese specimen (LBEOW1857-11) is only 0.3%. Thus, due to lack of any stable morphological characters or significant genetic distance whithin P. otus , we do not divide it into subspecies.
