Other Saudi Arabian records: Asir Region: Maraba: 60 km S of Abha; Wadi Hali (Dawah & Abdullah 2006); Garf Raydah Nature Reserve (El-Hawagry et al. 2017).

Distribution. This species was previously recorded from Saudi Arabia by Dawah & Abdullah (2006) and El- Hawagry et al. (2017). It was described from Colombo, Sri Lanka (female) and Nepal (male). The species was further recorded from the following areas: Afrotropical Region: Cape Verde Islands, Democratic Republic of Congo, Mauritius, Oman, United Arab Emirates and Yemen; Oriental Region: Nepal, Sri Lanka and Thailand.

Remarks. Cresson (1943a: 4) described H. latipalpis from a single female from Colombo, Sri Lanka while Zatwarnicki (1988: 602) described the male of H. latipalpis from Nepal. Recently Deeming (2002) found that the male genitalia of H. latipalpis is identical to that of Hydrellia binotata, which was described by Canzoneri & Meneghini (1969: 126) from Democratic Republic of Congo and he placed H. binotata as a junior synonym of H. latipalpis . All known species of Hydrellia have larvae that are phytophagous. Most mine in leaves and stems of aquatic plants but some attack terrestrial plants, especially Poaceae (e.g. rice).
