Name
Dichoteleas striatus Schwartz & Van Noort & Johnson, 2023 sp. nov. – Wikispecies link – ZooBank link – Pensoft Profile
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: present. Color of pronotum: dark brown to black. Pronotal cervical sulcus: present. Mesepimeral sulcus: present. Sulcus along mesopleural carina: absent. Mesoscutal suprahumeral sulcus: present. Mesoscutal humeral sulcus: present as an uninterrupted groove. Median mesoscutal line: absent. Color of mesoscutum: dark brown; black. Sculpture of mesoscutum: primarily smooth with longitudinal striations between notauli. Notaulus: complete. Visibility of notaulus: slightly obscured by mesoscutal sculpture. Parapsidal line: present. Sculpture of mesoscutellum: smooth. Shape of axillular carinae in lateral view: without a posteroventral hooklike projection. Color of axillular carina: brown. Sculpture of T3–6: weakly strigate and finely punctate. Median carina on T1–T4: absent.
Diagnosis
This species can be distinguished from D. ambositrae by the longitudinal striations between the notauli and the black/brown pronotum and from D. rugosus by its glabrous mesosoma.
Etymology
The epithet refers to the longitudinal striations present on the mesoscutum. This epithet is treated as an adjective.
Distribution
Madagascar (Antananarivo, Antsiranana, Fianarantsoa, Mahajanga, Toamasina).
Material examined
Holotype, female: Madagascar: Prov. Fianarantsoa, 1130m, PN Ranomafana, radio tower; CASENT 2043988 (CAS). Paratypes. Madagascar: 93 females, 64 males, CASENT 2043198, 2043540, 2043564–2043565, 2043989, 2118400, 2118404, 2118444, 2131303–2131316, 2132729, 2132737, 2133921–2133922, 2134086, 2134150, 2134156, 2134161, 2134169, 2134198–2134200, 2134203– 2134204, 2134523, 2135869, 2135989, 2136263, 2136415, 2137236, 2137832, 2137876, 2137937, 2138216 (CAS); CASENT 2042824, 2042844–2042857, 2042967–2042976, OSUC 146657, 229802 (OSUC); OSUC 218026 (USU); OSUC 874879–874883, 874885–874886, 874888–874941, 874943–874964 (CNCI).
Comments
There was some variation in the length and the number of the longitudinal striations on the mesoscutum. In fewer than half of the specimens, the striations started anteriorly and terminated around the middle of the mesoscutum. In the majority of the specimens, the striations started anteriorly and terminated at the posterior margin of the mesoscutum.
