Description

Pinkfloydia Hormiga & Dimitrov, 2011

Type species: Pinkfloydia harveii Dimitrov & Hormiga, 2011

Diagnosis (modified from Dimitrov & Hormiga 2011): Pinkfloydia can be easily distinguished from all other tetragnathid genera by the conspicuously enlarged PME placed on short ocular protrusions and by the conical and distinctively elevated cephalic area; all other eyes are placed at the same level on the prominent cephalic region and are much smaller in size (Fig. 1). Males of Pinkfloydia differ from other tetragnathid males in having several conspicuously large macrosetae at the base of the paracymbium (Figs. 2A, B, F, 3C, H) and an area of the cymbium covered with numerous modified short setae (cuspules) concentrated dorsally on the cymbial ectomedian process (Figs. 2C, D). In addition, in Pinkfloydia the male palp has a well-developed metaine embolic apophysis and an embolus that carries numerous short denticles (Figs. 2A, F, 3B, G); the cymbium has prominent cymbial ecto-basal and cymbial ecto-median processes (Figs. 2A, F, 3C, H). Females are diagnosed by the presence of a flat epigynal plate that has numerous pores opening on its ventral surface (Fig. 2E; no similar plate has been described in any other member of Tetragnathidae). Copulatory openings are displaced caudally and hidden by the distal edge of the epigynum in a transversal groove (Fig. 3E).
