Diagnosis.

This species can be distinguished from the other species of the genus Logasa by the following combination of characters: antennomeres II and IV rectangular and longer than wide ( Fig. 1 e–f ), apical lobe of male genitalia forked into two lobes, major lobe longer with three branches, parameres with over ten setae, and right lobe shorter and wider ( Fig. 3a ).

Description.

Length 2.1-2.5 mm. Body yellowish to reddish-brown ( Fig. 1a ). Head. Head triangular with frontal fovea and vertexal foveae. Antennomeres with tubercles and long setae ( Fig. 1 e–f ). Antennomere I elongate, II rectangular, III subquadrate and smallest, IV rectangular, V rhombic, VI—X gradually transverse ( Fig. 1 e–f ). Thorax. Pronotum with deep sulcus and pair of lateral antebasal foveae. Each elytron with basal elytral foveae and discal elytral foveae. Abdomen. Tergite IV with pair of transverse patches of microtrichia ( Fig. 1a ). Aedeagus. Apical lobe of male genitalia forked into two lobes, major lobe longer with three branches, minor lobe short and simple ( Fig. 3a ). Phallobase of median lobe asymmetric and rounded ( Fig. 3a ). Parameres asymmetric with over ten setae, left paramere longer and narrower than right ( Fig. 3a ).

Distribution.

New South Wales ( Fig. 4 : square).

Habitat.

Specimens of this species were collected using flight intercept traps, window traps, or by sifting leaf and log litter in wet sclerophyll forests.
