Types. Holotype, male, Barrow Island , Western Australia [Site LTR1], 20°47'57"S, 115°26'20"E, 15.iii.2006, S. Callan and R. Graham ( WAM, ex ASCU: ASCTHE 033199 )

Paratypes: WESTERN AUSTRALIA, 2 males, same data as holotype ( ASCU) ; 1 male, same data as holotype but [Site N 01], 20°49'35"S, 115°26'40"E, 6.v.2007 ( ASCU) ; 8 males, 19 females, Nullagine, 19–20.i.1974, A.M. and M.J. Douglas ( WAM)

Diagnosis. This species differs from other Australian species in having the aedeagus shorter and broader with indications of the gonopore apparent in the concavity of the dorsal margin when viewed laterally and in having the subgenital plates more or less ovate and lacking a distinct angle where the outer and inner margins meet. In this feature, the species resembles the widespread Palaeotropical species M. distincta (Motschulsky) (as figured by Zhang & Duan 2011: Fig. 9a , but less like the figure by Webb &Viraktamath 2009: Fig. 34e) and M. webbi Zhang & Duan although the aedeagus of M. barrowensis is is shorter and thicker than that of both species.

Description. Length (males): 3.2mm. Light brown with extensive darker brown markings. Face extensively dark brown including arcuate lines apically below margin. Vertex with line of apical black spots tending to join together. Tegmen brown with darker infuscations in most cells, brown patch in inner cell of clavus and basally in second anteapical cell.

Male genitalia. Pygofer with posterior margin convex and incurved. Subgenital plates rounded oblong, the outer curved margin curving into the inner margin, internal ridging not evident, with marginal setae in single row along apical half of plate with tuft of hair setae at apex of plate. Paramere with prominent preapical shoulder apically acute bearing two short setae on distal edge; apical process well developed, long, relatively thick and slightly curved laterally, more so over apical half with small tooth preapically in some views. Connective with arms diverging to about midlength then converging to contiguous with each other apically, connecting to aedeagus at posterior edge of base of aedeagus with no apparent discontinuity between outline of connective and posterior margin of aedeagus. Aedeagus relatively short, in posterior ventral view, parallel-sided from base to near apex then curved to bluntly pointed apex; in lateral view, lightly tapered in basal half, then tapered to acute apex with upper margin concave.

Distribution. Australia (WA)

Etymology. The species name reflects the type locality of Barrow Island, WA.
