Protosticta feronia Lieftinck, 1933: 281–285 View in CoL , Fig. 1 View Fig ; 1954: 31 (part, west Borneo); 1971: 88; Orr, 2003: 38, 69 (part); van Tol, 1992: 23, 88, 99, 247; van Tol et al. 2009: 8, 18, 36

Material examined. — Holotype: male (JvT 3072), together with female (JvT 17087), Indonesia, Kalimantan Barat, Singkawang, Gunung Poteng, 1 Nov.1931, coll. L. Coomans de Ruiter , in RMNH.

Paratypes (all with same data as holotype except as noted, all in RMNH): male (JvT 13481), 31 Jan.1932 ; female (JvT 28062), 13 Mar.1932.

Others (all from Indonesia, Kalimantan Barat, Singkawang area , all coll. L. Coomans de Ruiter): male, 1[?] Jan.1932 , Gunung Poteng ; female, 28 Feb.1932 , Gunung Poteng ; male, 19 Jun.1932 , Gunung Poteng ; male, female, 14 Jul.1932 , Gunung Poteng ; male, 21 Aug.1932 , Gunung Poteng ; male, 16 Oct.1932 , Gunung Poteng; male, Bajak , 10 Jun.1933 ; male, Gunung Mandor, Tjapkala , 24 Aug.1933 .

Diagnosis. — The male of T. feronia is distinguished from all other species of Telosticta except T. bidayuh by the combination of moderate length antehumeral stripes and long lateral processes on the posterior pronotal lobe, superior appendages with poorly developed dorsal projections and a flattened but not strongly folded apical part with at most a small notch in the tip as seen in normal lateral view. It is distinguished from T. bidayuh by the markings of the labrum and terminal abdominal segments and by the position of the internal projection of the superior anal appendage, placed at the point where the basal part of the appendage contracts in T. feronia but well distal to this point in T. bidayuh , and by the generally more robust build of the superior appendage in T. feronia compared to T. bidayuh .

Measurements (mm): Males: Abdomen without anal appendages 34–36, Hw 20–21. Wings with 11–13 Px in Fw, 10–12 in Hw. Females: Abdomen without appendages or ovipositor 29–31.5, Hw 20.5–22. Wings with 11–12 Px in Fw, 10–12 in Hw.

Remarks. — As with T. dupophila, Lieftinck (1933) failed to mention the lateral processes of the posterior pronotal lobe. The ratio of the width of compound eye to width of vertex measured at level of lateral ocelli is over 0.9. Aside from small differences in markings and size, no significant variation was found in the type series and other old topotypical material. In the absence of fresh material little can be added about this species.

Biological notes. — All that has been recorded on the habitat of this species is that the type series were collected at a “forest-brook” at 325 m.

Distribution. — Fig. 19 View Fig ; known only from the Singkawang area in west Kalimantan.
