Antillocladius is a genus of midges belonging to the family Chironomidae, subfamily Orthocladiinae. The name Antillocladius means orthoclad (subfamily Orthocladiinae) that occurs in the Antilles, where it was primarily recorded. Distribution The genus Antillocladius is distributed in the Nearctic, Neotropical, Palaearctic (East Asia) and Indomalayan realms. The genus was erected by Sæther (1981) based on A. antecalvus Sæther, 1981, from the British West Indies: Saint Vincent and Saint Lucia. Subsequently, Sæther (1982) described two new species from the southeastern United States (Antillocladius arcuatus and Antillocladius pluspilalus) and emended the genus. Wang and Sæther (1993) described two additional new species from Palaearctic and Oriental China. Andersen and Contreras-Ramos (1999) described the first species from Continental South America (Ecuador). The genus was revised by Mendes, Andersen & Sæther (2004), with the addition of nine species, plus two Japanese species transferred to the genus (Yamamoto, 2004). Recently the genus was revised by Mendes & Andersen (2008) with the addition of 7 new species from Brazil and a new combination of a species from India.
