Dichoteleia ambositrae Risbec, 1956: 261 (original description).

Dichoteleas ambositrae : Masner, 1976: 31 (type information); Johnson, 1992: 367 (catalogued, type information).

Description.

Color of head: black. Hyperoccipital carina: present. Frontal depression: absent. Malar striae: absent. Facial striae: present. Setation of eyes: absent. Sculpture of frons: primarily smooth with weak transverse striations above the IAP. Setation of frons: mostly glabrous with sparse setation laterally. Submedian carina: absent. Interantennal process: undifferentiated. Central keel: absent. Transverse pronotal carina: absent. Color of pronotum: yellow. Pronotal cervical sulcus: present. Mesepimeral sulcus: present. Sulcus along mesopleural carina: foveolate. Mesoscutal suprahumeral sulcus: present. Mesoscutal humeral sulcus: present as an uninterrupted groove. Median mesoscutal line: absent. Color of mesoscutum: dark brown to black. Sculpture of mesoscutum: smooth without longitudinal striations. Notaulus: incomplete. Visibility of notaulus: unobscured. Parapsidal line: present. Sculpture of mesoscutellum: smooth. Shape of axillular carinae in lateral view: without a posteroventral hooklike projection. Color of axillular carina: yellow. Sculpture of T3-6: punctate. Median carina on T1-T4: absent.

Diagnosis.

This species can be distinguished from D. subcoeruleus , D. fulgidus , and D. fuscus by the absence of the median carina on T1-T4. It can be distinguished from the other species by its xanthic pronotum and smooth mesoscutum.

Distribution.

Madagascar (Ambositra, Fianarantsoa).

Material examined.

Holotype, female: Madagascar: Ambositra, MNHN Paris EY 32526; Madagascar: 2 females, CASENT 2138155, 2138157 (CAS).
