Diagnosis.

This species can be distinguished from the other Logasa species by the following combination of characters: antennomeres II and IV rectangular and longer than wide ( Fig. 1 g–h View Figure 1 ), apical lobe of male genitalia not divided, left paramere of male genitalia curved to left ( Fig. 3b View Figure 3 ).

Description.

Length 1.6-2.5 mm. Body yellowish to reddish-brown ( Fig. 1b View Figure 1 ). Head. Head triangular with frontal fovea and vertexal foveae. Antennomeres with tubercles and long setae ( Fig. 1 g–h View Figure 1 ). Antennomere I elongate, II rectangular, III subquadrate and smallest, IV rectangular, V—VII rhombic, VIII—X gradually transverse ( Fig. 1 g–h View Figure 1 ). 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. 1b View Figure 1 ). Aedeagus. Apical lobe of male genitalia not branched ( Fig. 3b View Figure 3 ). Phallobase of median lobe asymmetrical and rounded ( Fig. 3b View Figure 3 ). Parameres of male genitalia asymmetrical, left longer than right and curved to left ( Fig. 3b View Figure 3 ).

Distribution.

New South Wales, Victoria ( Fig. 4 View Figure 4 : circle).

Etymology.

This species is named for one of the co-collectors of the holotype and world-renowned beetle specialist, Alfred F. Newton.
