Genus Logasa Chandler, 2001
Logasa Chandler, 2001: 47.
Type species.
Logasa novaeanglia Chandler (designated by Chandler 2001: 47).
Diagnosis.
Members of this genus are easily separated from other faronite genera by the following combination of characters: head with long frontal sulcus, closed anteriorly ( Fig. 2a View Figure 2 ); elytra rectangular and longer than wide, hind wings fully developed ( Fig. 1 a–d View Figure 1 ); mesoventrite with lateral mesosternal fovea, promesocoxal fovea, and lateral mesocoxal fovea ( Fig. 2b View Figure 2 ), and round setal patch at center (Fig. 2 b: arrow); metaventrite with metasternal fovea and median metasternal fovea ( Fig. 2b View Figure 2 ); male abdominal ventrite VIII with setose depression ( Fig. 1m View Figure 1 ) located at middle; abdominal ventrites without basolateral fovea; length of abdominal ventrites and tergites VI–VII longer than others ( Fig. 1 a–d View Figure 1 ); female abdominal ventrite IX with two pairs of long setae ( Fig. 2c View Figure 2 ); parameres of male genitalia asymmetric and shorter than apical lobe ( Fig. 3 a–d View Figure 3 ); phallobase of median lobe rounded and asymmetric ( Fig. 3 a–d View Figure 3 ).
Distribution.
Southeast Australia (New South Wales, Victoria, Tasmania).
Comments.
All specimens, both male and female, of the genus Logasa have fully-developed hind wings, and many specimens were collected by flight intercept traps. Members of this genus are usually found in temperate or rainforest habitats in southeastern Australia. Male specimens have a setose depression located at the middle of abdominal ventrite VIII as a secondary sexual character, but this is not easily observed on some specimens. Abdominal ventrite IX is important for recognizing the sex of specimens: in males ventrite IX is usually fragile and partially concealed by ventrite VIII; in females it is more robust, triangular and bears a pair of long setae ( Park and Carlton 2014).
