Calosoma (Carabophanus) arrowi Breuning, 1928: 94 (type: Abissin; British Museum of Natural History, London)
Carabomorphus (Carabophanus) arrowi Lapouge, 1932: 397
Orinodromus (Carabophanus) arrowi Jeannel, 1940: 145
Calosoma (Carabophanus) excellens Beheim & Breuning, 1943: 21 (type: Addis Abeba; coll. Vogt, Zoological Museum of the University of Amsterdam)
Carabophanus arrowi Basilewsky 1962: 33
Carabophanus arrowi var. gestroides Rougemont, 1976: 258 (type: Geech Amba; Musée Royal de l'Afrique Central, Tervuren)

Length 13-18 mm. The species was described on a single female specimen preserved at the British Museum, which had been noted without receiving a name by Roeschke (1900a: 72). The male was later described by Basilewsky (1962: 33).
The pronotum of C. arrowi is slightly sinuate in the rear, with lobes more or less developed. The femurs are constantly red and two raised lines run parallel to the suture of elytra along its entire length. The colour of the upper body is very variable: green with golden hues, cupreous, dark green, blue-black (arrowi var. gestroides), but arrowi is always easily identifiable because of the series of opaque black spots, aligned in correspondence with the striae of the elytra.
According to Rougemont (1976: 258), Calosoma (Carabophanus) excellens must be considered a synonym of Calosoma (Carabophanus) arrowi .
arrowi occupies the north of the former province of Shewa, and the provinces of the Gojjam and Begemder up to Simien massif, and it partly overlaps, in the north, the habitat of raffrayi and the one of antinorii in the south.

Examined specimens and literature’s data
Ethiopia. Abissin (holotype, BMNH); Shewa: between Debre Birhan and Ankober 3100 m (AVT, EM, GP, SB), Chacha valley (Rougemont, 1976: 255); Termaber Pass 3100 m (SB); Ambagir (10°44’N; 37°59’E) (Rougemont, 1976: 255)
Wollo: Simien mountains, Geech Amba (RMCA)

Notes: Wingless. Adults are mostly nocturnal and shelter during the day under stones and tufts of grass, but some of them were found in activity even in bright sunlight. It lives in pastures,tilled fields and fallow land, between 3200 and 3400m., always in an environment characterized by high soil moisture. In Shewa region, adults were found in activity of mating and oviposition in the beginning of the first rainy period between February and April. Development from egg to adult is expected between March and June. The adults reappear at the end of the second and more important rainy period and are active from October to April, but in case of severe drought, they shelter in cells deeply buried beneath stones.
The description of first and second stage larva is found in Vigna Taglianti & Bruschi (1986: 18).
The species is named after Gilbert John Arrow (1873 - 1948) an English entomologist on the staff of the Natural History Museum in London from 1896 until 1938.
