Family Ilyocryptidae Smirnov, 1992

Ilyocryptus spinifer Herrick, 1882

Synonyms in Philippine literature: Ilycryptus longiremis Sars, 1888 and Ilyocryptus verrucosus Daday, 1905 .

Philippine records: Mamaril, 1986, 2001.

General geographic distribution: This is a common species distributed from North and South America, South Asia and Australia.

Distribution in the Philippines. Luzon: Batangas –Nasugbu; Bulacan –Bustos Dam and Malolos; Cagayan –Buguey; National Capital Region–La Mesa Dam, Marikina, and UP Diliman Campus; Manila-Laguna-Rizal: Laguna de Bay; Nueva Ecija –Pantabangan Dam. Negros: Negros Occidental – Bacolod; Negros Oriental –Sibulan. Mindanao: Agusan del Norte –Lake Mainit; Lanao del Sur –Lake Lanao.

Remarks. It is the dominant species of Family Ilyocryptidae in most freshwater bodies of the tropics and subtropics ( Jeong et al., 2012; Kotov & Sanoamuang, 2005). It is usually associated with large tropical lakes with a good coverage of vegetation ( Kotov & Stifter, 2006). Philippine population needs to be compared with others to determine morphological differences among population and identify probable sibling species ( Frey, 1982; Kotov & Elías-Gutiérrez, 2009; Kotov & Sanoamuang, 2004).
