Type material. Holotype ♂. PHILIPPINES, Talamban, Cebu City, Small forest behind University of San Carlos., 16–18 August 1986, Gerd Alberti (QM S22518 a) . Paratypes 1 ♀ allotype, same data as holotype (QM S22518 b) .

Diagnosis. Phlogiellus raveni sp. nov. differs from other Phlogiellus species, except P. aper, P. brevipes, P. mutus, P. bundokalbo, P. watasei, P. moniqueverdezae, P. longipalpus, and Phlogiellus daweiensis sp. nov. in lacking a maxillary lyra in both males and females. Phlogiellus raveni sp. nov. differs from those of the alyrate species of Phlogiellus, in the different shape of the male palpal bulb and shape of the female spermathecae (Figs 13, 17).

Scopulae division: undivided on leg I–II and metatarsi III; clearly divided with rows of setae on tarsi III–IV, undivided but possessed row of setae on metatarsi IV. Spines: absent on metatarsi I; metatarsi II with 2 dV; metatarsi III with 3 dV, and 2 dD and metatarsi IV with 3 dV and 2 dD. Genitalia (Fig. 14): subtegulum distinct; haematodoca well developed; tegulum tapering and partly concave; embolus short, overall tapered and further tapering to the tip; with distinct basal lobe and strong retrolateral keel; embolus tip slightly bent.

Etymology..—The new species is dedicated to Dr. Robert J. Raven, the senior curator ( Arachnida) at the Queensland Museum, Australia for his incalculable contribution to spider systematics.
