J. Bergsten ( NHRS ) . Paratypes : 10 females , same data as holotype ( NHRS , MCZ , BMNH , PBZT / MBC ) . Differential diagnosis . Habitus as in Fig. 26 (imaged pre-dissection). Slightly larger in size than H. saboureaui (length to elytral apices ca. 0.82 vs. 0.79 mm ), but with a smaller aedeagus, which has a much smaller internal sac ( Figs. 27, 28 ). Also refer to the differential diagnosis of H. saboureaui , and see comparative notes following that species. Description ( holotype male): Size (mm): length to elytral apices 0.82, total length 0.99 (variable due to telescoping last abdominal segments), width 0.46. Color dark brown to black, with legs, palpi and antennae lighter, testaceous in parts. Habitus as illustrated ( Fig. 26 ). Aedeagus and terminal abdominal segments as illustrated ( Figs. 28 , 30, 32-33 ). Dorsum very finely sparsely punctate and with very indistinct short sparse setae. Configuration of ventral morphology typical for the genus. See comparative notes in section on H. saboureaui .
