Type locality: Mindanao, Surigao, Iron Deposit (Type in MTD, examined).

Type category: Holotype (female).

Distribution: Species is widely distributed from North – East to Central part of Mindanao Island, including: Surigao del Sur, Agusan del Sur, Compostella and Davao region.

Material examined: PHILIPPINES / Mindanao, Surigao del Sur / Marihatag / XII. 2018 / local collector leg. (1 male) // I. 2019 (1 male, 3 female) // PHILIPPINES / Mindanao, Agusan del Sur ,

Rosario / IX. 2018 / local collector leg. (1 male, 1 female) // X. 2018 (1 female) // PHILIPPINES / Mindanao, Agusan del Sur, Luagon / III. 2019 / local collector leg. (1 male) // PHILIPPINES / Mindanao, Agusan del Sur, San Francisco / XII. 2018 / local collector leg. (1 male, 1 female) // PHILIPPINES / Mindanao, Compostella, Monkayo , Filomena / XII. 2018 / local collector leg. (1 male) // I. 2019 (1 female) // PHILIPPINES / Mindanao, Davao, Kapatagan / IV. 2019 / local collector leg. (2 males) // PHILIPPINES / Mindanao, Davao, Mt. Apo / XI. 2016 / local collector leg. (2 males) . Total : 17 ex. (10 males, 7 females) .

Remarks: Schultze in his early work reported, that several specimens of the species have been found of Biliran Island near Leyte. After examination of species material from Leyte Island available at MTD we concluded, that upper mentioned individuals belong to other species: C. leytensis Leitāne & Rukmane-Bārbale, 2020 . Species is closely related to C. leytensis distributed at Leyte island and C. mundocostata from Samar Island. Most uncertain method to distinguish species is compare shape of everted aedeagus, that is species specific.
