This paper reports on some interesting taxa recently found in the Arabian Peninsula and the island of Socotra. Among them is a new species of brachypterous grasshopper Sphodromerus carapezzanus sp. n. (Acrididae: Calliptaminae), described from an isolated area in Dhofar (Oman). A female Heteracris hemiptera (Uvarov, 1935) (Acrididae: Eyprepocnemidinae) is reported, with morphological characters which do not fully comply with those of any known subspecies. Two species, hitherto rarely documented, are also reported, Phaneroptila insularis Uvarov, 1957 (Tettigoniidae: Phaneropterinae) from Socotra and Cataloipus thomasi Uvarov, 1933 (Acrididae: Eyprepocnemidinae) from Oman. Pycnodictya dentata Krauss, 1902 (Acrididae: Oedipodinae) is reported from Saudi Arabia, constituting a new record for the country.
new records, new species, Oman, Sphodromerus carapezzanus sp. n., taxonomy
The Arabian Peninsula is located between the two wide continents of Africa and Asia, its fauna containing species of Asian and African origin. The Orthoptera fauna of the Arabian Peninsula is quite well known; the list of Ensifera and Caelifera is very long and no less than 190 taxa have been reported (
Taxonomical arrangement follows that of Cigliano et al. (

Yemen, Socotra, Wadi Ayhaft 23.I.2014, 12°23'35"N, 53°59'18"E, A. Carapezza (2♂) (BMPC).
Only one species, endemic to Socotra, is known from this genus. A previous record from this taxon is that of a male holotype, collected on 15 March 1953 along the northern slopes of the Hagghier, at Hijama (Hadiboh Plain) (

This species is considered to be an endemic taxon to the southern Arabian Peninsula, known only from Dhofar region. According to

Measurements (in mm). Female. Body length: 30.3; length of pronotum: 7.0; height of pronotum: 6.0; length of tegmina: 16.2; length of hind femur: 18.9; height of hind femur: 4.6.

Pycnodictya dentata can be separated from P. galinieri (Reiche & Fairmaire, 1849) by its blue hind tibiae (purplish in P. galinieri) and sinuated posterior lower angle of the pronotal lobes (not sinuated in P. galinieri); the color of the hind wings may vary and is not diagnostic (

Sphodromerus carapezzanus is very peculiar for its color, brown with tegmina venation being dark and cream spotted. Hind femora with a white base and red outer carinulae, lower genicular lobe white, with the upper part brown, inner face of femora black-reddish, inner tibiae red, outer face of tibiae whitish, spines are black tipped. Carinae of pronotum are distinct in prozona, well visible in metazona.

The species is assigned to the Calliptaminae genus Sphodromerus Stål, 1873, based on modified male cerci with a single apical tooth and robust femora. The majority of species are described on the basis of their coloration, which seems to be unreliable in similar genera (e.g. Calliptamus Serville, 1831) (
(in mm). Male. Body length: 23.6; length of pronotum: 4.8; height of pronotum: 5.3; length of tegmina: 11.4; length of hind femur: 12.8; height of hind femur: 4.5. Female. Body length: 28.7–31.9; length of pronotum: 8.3–8.6; height of pronotum: 7.7–8.3; length of tegmina: 16.8–17.9; length of hind femur: 18.6–18.8; height of hind femur: 6.4–6.7.
Named for Attilio Carapezza, distinguished Italian heteropterologist, who collected most of the Orthoptera here reported in Oman.
Wadi Ayun (Arab = Valley of sources) is a very isolated narrow strip of green in an otherwise parched region; at the bottom there are deep pools of flowing blue-green water around sedges and grasses. A rocky desert surrounds it for dozens of kilometers (Fig.
I am indebted to Attilio Carapezza, who provided the specimens collected from Oman and Socotra. I also thank Josip Skejo and one anonymous referee for their useful comments and suggestions on a first manuscript. I am also very grateful to John J. Borg for the English revision.
