Description.

Body length: 3.5-4.4 mm.

Color as in generic description (Fig. 1 ).

Male 2S apodemes not extending to end of segment V (Fig. 3 ). Anal-tube appendage hook-shaped at apex (Fig. 4 ). Male pygofer strongly emarginate dorsally in profile, and posteriorly extended into sharp point with spine-like setae; ventral appendage absent; bearing one long macroseta near dorsal margin (Fig. 4 ); dorsal bridge with a posterior lobe-like projection each side of midline, in dorsal view. Subgenital plate surpassing pygofer lobe, broadened medially in later view, all categories of setae represented (Fig. 4 ). Connective anterior margin with undeveloped median lobe, posterior margin notched medially (Fig. 7 ). Style sinuate (Figs 4 , 8 ). Aedeagus without preatrium, basal apodeme well developed, plate-like; shaft with pair of lamellate lateral processes; gonopore subapical, ventrad (Figs 5 , 6 ).

Etymology.

The name is derived from the Latin words brevis (short) and penis, which refers to the very short aedeagal shaft.

Distribution.

Brunei, Malaysia.

Notes.

Specimens of S. brevipenis were considered aberrant specimens of S. distincta by Dworakowska (1995) and of uncertain status. However, based on the high degree of difference between these two species and the discovery of two similar new species from Papua New Guinea noted in Xu’s (2019) PhD thesis, we describe the above specimens as a new species. All type specimens listed here (with some amendments) were identified by I. Dworakowska as the aberrant form of S. distincta . All are male and most have a Dworakowska genitalia dissection affixed to a card placed beneath the specimen. Three females (NHM) with identical data to the males could be the same species but, as three other species are also from these localities (see Checklist), their identity is uncertain. See also the concluding comments under the genus description. In Dworakowska’s (1995) figure of the head and thorax there are some fine lines in the basal triangles of the mesonotum. These are seen in some specimens, but it is not clear if they are markings or perhaps caused by shrinkage of internal tissue during drying.
