Thayer 807 / FMHD #87-206 / flight intercept / (window) trap". Paratypes (N = 6; 2 males, 4 females). Australia: VIC: 1♂ 2♀♀ (1♂ aedeagus dissected and whole body placed in micro-vial, 1♀ slide mounted, UNHC), 10 km east of Maryville, 27 XI 1986, D. Burckhardt; 1♀ (UNHC), Belgrave, V.F.E. Wilson, I 1922, fallen leaves (MV); Australia: Tasmania (TAS): 1♂ (aedeagus dissected and whole body placed in micro-vial, MV), Zeehan, 16 IV 1895; 1♀ (MV), Mt. Wellington, I 1948, C. Oke.

Diagnosis.

This species can be distinguished from the other Logasa species by the following combination of characters: antennomeres II and IV subquadrate ( Fig. 1 i–j View Figure 1 ), apical lobe of male genitalia not divided, left paramere of male genitalia curved to right, and right paramere divided into two lobes apically and curved to right ( Fig. 3c View Figure 3 ).

Description.

Length 2.0-2.3 mm. Body yellowish to reddish-brown with long setae ( Fig. 1c View Figure 1 ). Head. Head triangular with frontal fovea and vertexal foveae. Antennomeres with tubercles and long setae ( Fig. 1 i–j View Figure 1 ). Antennomere I elongate, II–IV subquadrate, III smallest, V–VI rhombic, VII—X gradually transverse ( Fig. 1 i–j View Figure 1 ). Thorax. Pronotum with the deep sulcus and pair of lateral antebasal foveae. Each elytron with basal elytral foveae and discal elytral foveae. Abdomen. Tergite IV with patches of microtrichia ( Fig. 1c View Figure 1 ). Aedeagus. Apical lobe of male genitalia not branched ( Fig. 3c View Figure 3 ). Phallobase of median lobe asymmetrical and rounded ( Fig. 3c View Figure 3 ). Left parameres of male genitalia curved to right ( Fig. 3c View Figure 3 ). Right paramere divided into two lobes apically and curved to right ( Fig. 3c View Figure 3 ).

Distribution.

Tasmania, Victoria ( Fig. 4 View Figure 4 : triangle).

Etymology.

This species is named for one of the co-collectors of the holotype and world-renowned beetle specialist, Margaret K. Thayer.
