Chłond 2009 [printed] / vial with genitalia. (MNHN) Paratype, brachypterous ♀: Museum Paris / BHOUTAN / MARIA BASTI / (M ar DUREL) / R. OBERTHÜR 1898; Paratype [printed on red label]; Sirthenea / kali n. sp. [handwritten] / det D. Chłond 2009 [printed] (MNHN).
Diagnosis. This species can be easily distinguished from other representatives of the genus from the Oriental Region by the following combination of characters: brachyptery, absence of ocelli, pronotum with distinct collar, posterior pronotal lobe with distinct transversal sculpturation, ridges of proepisternum and proepimeron not connected in entire length.
Description: Color: Body generally black (or dark brown) with yellowish hemelytron (Figs. 94, 176). Area of interocular furrow, clypeus, antennomeres paler. Eyes black. Basi- and distiflagellum with darker basal and apical parts. Intercalar segments pale. All labial segments brown, paler than head in black specimen. Hemelytron yellowish, dull (except shining apical part) with long, golden setae and dark membrane (Figs. 157, 176). Clavus pale with dark margins in black specimen. Black specimen with dark veins. Coxa with paler apical parts. Middle and hind trochanters, fore and middle tibia as well as tarsus pale. Fore femur with golden and dark setae. Middle and hind femur black or brown with paler basal and apical part and with golden setae. Hind tibia dark with paler apical and basal part. Ventral side of thorax black or brown with black spots and with pale setae. Abdomen with dark spots and golden setae.

Structure: Body medium-sized and slender with shinning head, pronotum and parts of hemelytron (Fig. 94). Head (Fig. 154) covered with long setae and two pairs trichobothrial setae. Area in front of clypeus with distinct sculpture. Anteocular part of head 2.8–3.1 times longer than postocular part. Eyes small, narrower than synthlipsis; posterior margin in lateral view S-like. Ocelli absent. Delicate depressions in place of absent ocelli and a dull, thin line connecting depressions with shallow interocular furrow. Apodeme depression of head small and shallow. Dorsal surface of antennifers smooth. Scape, short club-shaped not reaching apex of head, thickened distally with rather long, erect setae. Pedicel slightly thickened and with a 2 trichobothria in basal part (Fig. 176). Pedicel, basi- and distiflagellum with dense, adherent, short setae and a several, regular arranged, erect setae. Second visible labial segment, basally enlarged, reaching posterior margin of eyes. Pronotum with long setae and distinct collar. Meso- and metasterna as well as abdomen ventrally with short setae. Anterior pronotal lobe sculptured with distinct, granulated, pilose (long setae) sulci and granulated apical margin. Anterior and lateral margins of anterior pronotal lobe with dense, medium-sized setae. Ridges of proepisternum and proepimeron not connected in entire length. Basal part of anterior pronotal lobe distinctly depressed (thin depression of median pronotal apophysis extend to 1/4 of length of lobe) and with distinct, triangular curvature of posterior margin behind depression. Middle part of posterior pronotal lobe of pronotum distinctly depressed and sculptured. Lateral parts of posterior pronotal lobe of pronotum without sculpture. Metapleura with two incomplete ridges. Scutellum with long, dense setae in basal part and distinct granulations in lateral parts. Hemelytron reduced, costal margin and membrane with variably-sized setae (Fig. 157). Femur, tibia and tarsus with spine-like setae (very dense in middle tibia and apical part of fore and hind tibia). Abdomen with spiracles III–IV placed distant from ventral connexival suture. First and half of second abdominal tergite with very distinct sculpture and granulations. Lateral parts of abdominal sternites with delicate sculpture. Ventral side of connexives distinctly wrinkled.
Genitalia: Valvifer I irregular in shape (Fig. 98). Outer side with delicate, longitudinal, depression near apical margin and numerous, small setae and a few longer setae. Styloids with rounded apex. On inner margin numerous spine-like setae and a few thin setae. Apical part of outer margin with few spine-like setae. Inner margin in apical half curved (Fig. 95). Basal part of valvula II convolute inwards with rounded indentation in apical part (Figs. 96, 97).
Measurements (in mm): Body length: 15.0–16.7; maximum width of abdomen: 2.8–3.0; head length: 2.9–3.2; head width: 1.7; length of anteocular part: 1.6–1.8; length of postocular part: 0.57–0.6; length of synthlipsis: 0.9– 0.97; lengths of antennal segments I:II:III:IV: 0.9–1.0: 1.3–1.5: 1.1–1.2: 1.3–1.4; lengths of visible labial segments I:II:III: 0.9–1.0: 2.1–2.3: 1.0–1.2; maximum length of anterior pronotal lobe: 2.6–2.7; maximum length of posterior pronotal lobe: 0.8–1.0; maximum width of anterior pronotal lobe: 2.7–2.9; maximum width of posterior pronotal lobe: 2.6–2.8; length of scutellum: 1.2–1.3; length of hemelytron: 2.5–2.8.
Male: Unknown.
Distribution: Northeast India (West Bengal) (Map 8).
Etymology: The name of this species originates from the name of Hindu Goddess Kali.
