Description.

Male (Figs 1-2, 5-7, 10-20).

Color. Dorsum and venter dull black, with ochraceous markings as follows: pair of longitudinal vittae submarginally along mesal margin of mandibular plates (indistinct around middle), and small spot between proximal extremities of above-mentioned vittae; pair of short, obliquely transverse streaks before mesal angles of eyes; proximomesal portion of ventral surface of clypeus; bucculae and surrounding areas between antennal insertions and basal neck-like portion of head ventrally; pair of small submedian spots on callar lobe of pronotum; pair of narrow submarginal vittae along lateral margin of pronotum, terminating slightly anteriad of humeral tubercle; undulating vitta connecting lateral extremities of anterior collar with humeral tubercles, following mesal margin of lateral explanate lobe of pronotum (indistinct around middle); pair of small sublateral spots on scutellum very close to anterior margin; narrow submarginal vitta around scutellum except extreme base; patch on metapleuron immediately anteriad of scent gland ostiole; distal (= lateral) portion of peritreme; small, rounded spot at posterolateral angle of metapleurite; dorsal laterotergites and adjacent lateral margins of ventral laterotergites of abdominal segments III–VII; pair of longitudinally elongate spots on each mediosternite of segments III–VII marginally (surrounding respective spiracles), and pair of smaller spots posteriad of the above ones on segments III–VI. Scape ochraceous, irregularly suffused with brown especially in distal half, pedicel, basi- and distiflagellum blackish brown; labrum ochraceous. Legs ochraceous, coxae with large dark brown patch on mesal surfaces; trochanters broadly suffused with dark brown distally, femora with several rounded brown patches on (morphological) anterior and posterior surfaces, with blackish brown longitudinal streak dorsoapically and black patches on anterior and posterior surfaces ventroapically, tibiae with few small, rounded, brown patches and longitudinal streak on nearly entire length of dorsal (furrowed) surface, tarsal segments suffused with brown apically.

Integument and vestiture generally as in generic description. Sternite VI with pair of fringes of long setae arranged along curved line following posterior margin of segment; dorsum of mandibular plates irregularly rugose, pronotum and scutellum with fine, dense, superficial, inconspicuous punctation, abdominal ventrites finely longitudinally wrinkled.

Structure.Head 1.85 times as broad as medial length (from base to imaginary line connecting tips of mandibular plates), 1.5 times as broad as interocular distance; mandibular plates (Fig. 5: mdp) produced anteriad as pair of subtriangular, apically narrowly rounded plates, mesal margins almost straight; distance between ocellus and ipsilateral eye 1.2 times as long as interocellar distance. Antenna (Figs 6-7): distipedicellite approx. four times longer than greatest width, 1.75 and 1.65 times longer than basipedicellite and distipedicellite, respectively. Labium reaching base of abdominal sternite V.

Thorax and pregenital abdomen as described for genus. Prothorax 2.2 times, scutellum 1.5 times broader than median lengths of respective sclerites.

External male genitalia.Genital capsule (Figs 10-11) broadly oval, posterior margin broadly rounded, slightly protruded posteriorly in mesal third, protruded part with tuft of several long, erect setae; lateral margin with pair of small, compact, brush-like clusters of strong, stiff setae subapically; morphological posterior surface weakly concave, infolding of dorsal rim broad, broadly and deeply impressed medially immediately dorsad of posterior aperture; infolding of ventral rim relatively broad; posterior aperture small, dorsal sinus broadly rounded, completely occupied by tergite X (Figure 11: t10); cuplike sclerite (Figure 11: cs) completely fused with infolding of ventral rim of genital capsule without trace of fusion line, provided with pair of thick suspensory apodemes (Figure 11: sus). Paramere (Figs 12-15) sickle-shaped, with short crown comprising broad stem and elongate, narrow apical process. Phallus (Figs 16-20): basal plates (Figure 17: bp), robust, fused with support bridge complex (Figure 17: sbc) by leaving pair of window-like interspaces open at two sides of median portion of support bridge complex, support bridge complex with broad ponticulus transversalis (Figure 17: pt); phallotheca (Figs 16-17: phth) elongate, greatly membranous, with protruding, diverticulum-like hinge (Figure 16: hi) proximoventrally, with pair of dorsolateral and single ventromedian sclerite distally, each dorsolateral sclerite with blunt, rounded, posteriorly directed tubercle at proximal part; conjunctiva elongate, wall of proximal portion with 4 pairs of sclerites: pair of elongate sclerites submedially, and three pairs of sclerites (derivatives of conjunctival processes?) laterally, apparently forming complex articulation for supporting proximal part of conjunctiva; distal portion with single elongate, membranous, tubular process dorsally (Figs 16, 19, 20: cp) provided with pair of very short, rounded, membranous diverticula subapically on posterior surface; aedeagus (Figs 16, 19, 20: aed) indistinctly demarcated from conjunctiva, weakly sclerotized, somewhat dorsoventrally compressed, produced into pair of flattened, fin-like expansions laterally, abruptly narrowed around middle, gradually tapering towards apex; endophallic reservoir elongate, endophallic duct thin, tubular, rather weakly sclerotized, gradually tapering to distal third, then desclerotized and closely surrounded by fine, transparent outer wall of aedeagus, forming thin, flexible tube.

Female (Figs 2-3, 21-23). Color, integument, and vestiture as in male. Terminalia brown, with long hairs on laterotergite IX and tergite X forming conspicuous, brush-like tuft around midline.

Structure.Head 2.3 times as broad as medial length, 1.5 times as broad as interocular distance; anterior outline evenly rounded, mandibular plates narrowly overlapping anteriad of apex of clypeus; distance between ocellus and ipsilateral eye subequal to interocellar distance.

Etymology.

Patronymic, dedicated to Thomas J. Henry.

Distribution.

Known only from the Malabar Subregion of southern India. The holotype and the two paratypes were collected at two localities around Pamba station below Sabarimala, a Hindu pilgrimage center, in Pathanamthitta District, Kerala State, separated by a distance of ca. 2 km.
