Description (holotype)

LENGTH. 2 mm.

HEAD. 1.2 times as long as broad, with broadest part behind the middle on a level with the lateral protuberances of the head ( Fig. 3A View Fig ). Lateral margins nearly straight. Central rod distinct, thin, with a node at the middle. Frontal branches present, no median branches. Dorsal surface covered by setae of subequal length. Cuticle with faint and dense pubescence ( Fig. 3B View Fig ).

ANTENNAE. Right antenna broken, left antenna 16 segments ( Fig. 3F View Fig ). First segment elongate, about 0.5 times as wide as long; 2 nd and 3 rd as wide as long; following segments of equal size, about 1.2 times as wide as long. Setae about 0.2 of diameter of segments, shorter in the most distal segments. No second whorl of setae. Apical segment subglobular. All segments with faint pubescence.

TERGITES ( Figs 3A, E View Fig , 7C View Fig ). First tergite rudimentary with six setae arranged in two groups of three. One short seta between first and second tergites in the median part ( Fig. 3E View Fig ). Second tergite with one seta between apical and inner basal setae of the triangular processes. Triangular processes with very small end-swellings ( Fig. 3E View Fig ). Margin between processes slightly curved. Second tergite with a total of seven posteromarginal setae, one central seta in the medial position. Five lateromarginal setae on the right side, short. Anterolateral setae slightly longer than the other lateromarginal setae. Only three lateromarginal setae visible on the left side. Third tergite with five posteromarginal setae, without setae between apical and inner basal setae of the triangular processes, seven lateromarginal setae on the right side, only four visible on the left side. All tergites with very faint, short and sparse pubescence.

LEGS. First pair of legs reduced to small spiny knobs, each with one distal seta ( Fig. 3C, D View Fig ). Last pair of legs with few and small setae. Tarsus with few long and curved setae in the distal part ( Fig. 3G View Fig ), absent in one paratype ( Fig. 3H View Fig ). Cuticle pubescent.

STYLI. Extremely short, barely visible ( Fig. 3I View Fig ).

CERCI. 3.2 times as long as wide, laterals slightly curved, with 10 dorsal setae long, slightly curved and depressed ( Fig. 3G View Fig ). Ventral side with five protruding and erect setae arranged in a longitudinal row ( Fig. 3H View Fig ). Cuticle pubescent. Terminal area conical, 0.14 times as long as the total length of the cerci, with 4 proximal striae straight and three distal striae curved and concentric. No apical setae, probably lost in all specimens.

Affinities and differential diagnosis

The species is similar to S. vulgaris ( Hansen, 1903) and S. asiatica Scheller, 1971 , since they share some similarities in the chaetotaxy of the two first tergites: six setae on the first tergite, seven posteromarginal setae on the second tergite with one central seta in the medial position and one seta between apical and inner basal setae of each triangular process. Further similarities in the chaetotaxy of the tergites are shared by S. kalundu sp. nov. and S. asiatica , such as 5 lateromarginal setae on the second tergite and 8 on the third one, while they are respectively 8 and 10 in S. vulgaris ( Hansen, 1903) . The absence of setae between the apical and inner basal setae of the triangular processes on the third tergite is characteristic of S. kalundu sp. nov. The chaetotaxy of the cerci is more similar to that of S. vulgaris ( Hansen, 1903) than the one observed in S. asiatica , since there is only one row of ventral setae erect, and there are no erect dorsal setae.
