Type locality. Cerocoma latreillei latreillei : “Unknown” ( Baudi 1878b). Based on the distribution of the nominate subspecies, we define here “ Baghdad ” as restricted type locality. Cerocoma latreillei sterbai : “Keredj” ( Mařan 1944).

Type specimens. The holotype of this species was not found in the MRSN. In a box in Baudi’s collection one card states that this type was sent for study to Zoltan Kaszab in Budapest, but it was not found at the HNHM either. The holotypes of Cerocoma sterbai and C. latreillei schah have been studied:

Holotype ♀: Keredj / Iran / Dr Kargl (white, printed) // TYPUS (red, printed) // Mus. Nat. Pragae / Inv. 18230 (pink, printed and handwritten) // Cerocoma ♀ / štèrbai m.n. / Dr. Mařan det. (white, printed and handwritten) ( CNM).

Holotype ♂: Firouzabad / 11-IV-53 / Kachkouli (white, handwritten) // Holotypus 1967 ♂ / Cerocoma Latreillei / schach / Kaszab (white with red frame, printed and handwritten) // Cerocoma latreillei / schach Kasz. / Dr Z. Kaszab det., 1968 (white, printed and handwritten) ( HNHM). The specimen lacks apical two left protarsomeres, right fore leg (except for the coxa), right meso- and metatarsi. Note that the published name “ schah ”, differs from that on the label, “ schach ”.

Description. Male. Body yellow-orange, except for thoracic sternites sometimes partially black; elytra metallic dark green, with short and sparse setae; posterior portion of head, behind eyes and around foramen, black; legs, antennae and mouthparts, including maxillary palpi, yellow-orange.

Head transverse with slightly protruding eyes. External sides of frontal calli, anterior to eyes, weakly concave. Maxillary palpi modified with palpomeres II–III wide, flattened and curved; IV flattened and curved and with base partially concealed by the apical edge of IV ( Fig. 3M ). Antennae strongly modified with antennomere I bearing a very wide and high dorsal keel partially curved at apex; III–VIII variously expanded and shaped; VI–VIII with rows of long and erect setae along the apical edge on ventral side; IX transverse with a deep dorsal concavity ( Fig. 2M ).

Pronotum transverse. Protibiae dorso-ventrally flattened and distally widened on the external side ( Fig. 4M ). Pro- and metatarsomeres slightly enlarged.

Gonostyli, in lateral view, straight, with apical lobes directed forward; apical lobes, in dorsal view, swollen and parallel. Apex of aedeagus rounded; aedeagal hooks equal in size. Sclerotised hooks of endophallus equal in size, both pointing backwards ( Fig. 6M ).

Female. Not modified. Refer to key for diagnostic characters.

Taxonomy. Cerocoma latreillei is a polytypic species with two subspecies: (a) C. latreillei latreillei , with male frontal calli anteriorly not raised, orange pronotum, protarsomere II longer than the III, and external side of protarsomeres curved ( Iran, Iraq); (b) C. latreillei sterbai , with male frontal calli anteriorly raised, black pronotum, protarsomere II about as long as the III, and external side of protarsomeres less curved ( Iran). After examining the holotype, we refer Cerocoma latreillei schah Kaszab, 1968 to the latter subspecies representing a colour variation (posterior portion of head, behind posterior margin of eyes, black).

Distribution. Iraq, Iran.
