Diagnosis

The following combination of character states distinguishes this species: body elongate-oval ( Fig. 5A View Fig ), length 2.36–2.85 mm; eyes of moderate size ( Fig. 5B View Fig ), unevenly rounded with distinctly stronger curvature posteriorly; temples very short; frontal grooves short, slightly curved, reaching anterior third of eyes; antennae short, stout ( Fig. 5D View Fig ), antennomere 6 slightly darkened, antennomeres 7–10 dark brown; antennomere 11 whitish; punctation on vertex dense ( Fig. 5B View Fig ), punctures strongly elongate, slightly longer than eye facet diameter, microsculpture absent, pubescence moderate; pronotum widest at anterior third ( Fig. 5C View Fig ), lateral pronotal margins with five small, but distinct teeth; I and V larger than II–IV, anterior denticles small, spread over larger distance and reaching anterior 1⁄6 of lateral margins, posterior denticles very small; pronotal punctation dense, punctures distinctly widened, microsculpture absent, pubescence moderate, setae directed antero-medially; elytra widest at middle ( Fig. 5A View Fig ), with elongate brown maculae along anterior 2/3 of margins and sutural area darkened near apex, striae wider than interstices, pubescence moderate, microsculpture absent; male genitalia strongly sclerotised ( Fig. 5 View Fig E–H), median lobe slender, evenly narrowed towards apex, tip blunt in dorsal and lateral view, parameres long, wide, apex thin, flattened and widened, lateral margin near apex with two long setae. Left paramere of holotype of P. vittifer   ( Fig. 5G View Fig ) permanently bent ventrally, probably a drying artifact.

Material examined

Types

AUSTRALIA • 1 ♂, holotype of Psammoecus vittifer Blackburn, 1903   ; “ Type | H.T.” [round label with red border]; “Australia. | Blackburn Coll. | B.M.1910-236.”; “ Psammoechus   [sic!] | vittiferus, Blackb.”; NHMUK.  

INDONESIA • 1 ♂, lectotype (here designated) of Psammoecus concolor Grouvelle, 1919   ; Java; “Co- | type ” [round label with yellow border]; “ Java.”; “Bowring. | 63.47*”; “ Psammoecus   | concolor Grouv.   ” [not Grouvelle’s hand]; Bowring leg.; MNHN   1 ♀; same data as for preceding; NHMUK   .

Of P. concolor, Grouvelle (1919: 8)   mentions two type specimens from Java in the collection of the NHMUK. Only one syntype (♀) could be located in the NHMUK collection; a further syntype (♂) with identical data is stored in the MNHN collection, indicating that Grouvelle kept one specimen for his own collection. The MNHN specimen is hereby designated as lectotype.

Distribution

This species was found in Australia (Queensland), Indonesia, Papua New Guinea and Thailand.

Remarks

Psammoecus vittifer   is easily identified by its general habitus and the very distinct structure of the male genitalia. One specimen from Papua New Guinea in the MSNG collection is labelled as “ Psammoecus ocularis   ty. Grouv.” in Grouvelle’s hand. This name was never published, hence P. ocularis   is considered a manuscript name.
