Crassignatha danaugirangensis sp. n. (Araneae: Symphytognathidae) was discovered during a tropical ecology field course held at the Danau Girang Field Centre in Sabah, Malaysia. A taxonomic description and accompanying ecological study were completed as course activities. To assess the ecology of this species, which belongs to the ground-web-building spider community, three habitat types were surveyed: riparian forest, recently inundated riverine forest, and oil palm plantation. Crassignatha danaugirangensis sp. n. is the most abundant ground-web-building spider species in riparian forest; it is rare or absent from the recently inundated forest and was not found in a nearby oil palm plantation. The availability of this taxonomic description may help facilitate the accumulation of data about this species and the role of inundated riverine forest in shaping invertebrate communities.

Diet studies have been an integral component of research related to the biology and ecology of animals for decades. Traditionally, morphological and visual approaches, such as gut, stomach, faecal and scat content analyses, are used to determine what a consumer has eaten (Miller & McEwen, 1995;Montague & Cullen, 1985). In this way, a qualitative list of dietary items can be obtained (Miller
