Etymology.—The name is a combination of andringitra – for the type locality and –ensis (L. suffix denoting place).


Head and pronotum tawny marked with piceous, castaneous and ochraceous, abdomen dark ochraceous marked with piceous and castaneous. Body covered with short white pile.


Head not as wide as mesonotum, castaneous with piceous from medial angle of eye to anterolateral corner of vertex, anterior and medial supra-antennal plate margin extending along epicranial suture anterior arm to anterior cranial depression, posterior head lateral to lateral ocelli and posterior epicranial suture ochraceous, short white on dorsal head, denser and longer posterior to eye. Ocelli rosaceous, eyes dark castaneous. Gena ochraceous with transverse castaneous fascia between eye and postclypeus, lorum castaneous with piceous posterior spot and ochraceous margin, dense short white pile and radiating long white pile on lorum and gena. Postclypeus castaneous dorsally, medially and on transverse ridges, lateral postclypeus and lateral transverse grooves ochraceous, ten transverse ridges, long white pile radiating from postclypeus, lateral postclypeus with white pile. Anteclypeus castaneous medially and posteriorly, ochraceous laterally, covered with short and radiating long white pile. Mentum ochraceous, labium ochraceous with piceous tip, rostrum radiating long golden pile, reaching to posterior of middle coxae. Proximal scape ochraceous, pedicel dark castaneous, remaining antennal segments castaneous.


Pronotum castaneous with darker fasciae on either side of midline, fusing posteriorly, expanding anterolaterally, piceous in ambient fissure from anterior between paramedian and lateral fissures to middle of lateral ambient fissure, becoming castaneous and continuing to posterior of posterior lateral fissure, anterior margin ochraceous. Pronotal collar ochraceous, castaneous in ambient fissure expanding onto collar, extending laterad across anterior pronotal collar lateral angle and pronotal collar lateral margin. Pronotum covered with short white pile and radiating long piceous pile, denser in some paratypes. Mesonotum castaneous with darker castaneous sigillae, lateral sigillae mottled, scutal depressions and transverse connection between anterior arms of cruciform elevation dark castaneous, mark extending across anterior or anterior arm of cruciform elevation, parapsidal sutures, cruciform elevation and wing groove ochraceous, wing groove with castaneous anterior spot. Metanotum ochraceous posteriorly, castaneous within wing groove. Dorsum with short white pile, denser and longer between anterior arms of cruciform elevation, between anterior and posterior arms of cruciform elevation, on posterior mesonotum, in wing groove, and on posterior metanotum. Ventral thoracic segments ochraceous except castaneous basisternum 2, and castaneous spot on either side of midline in basisternum 3, covered with short white pile and radiating long white.


Fore wings and hind wings hyaline with eight and six apical cells respectively. Venation ochraceous except piceous spot on base, piceous radius & subcostal vein along distal basal cell, and piceous proximal anal cell 2 + 3. Basal cell about five times longer than broad. Pterostigma absent. Basal membrane of fore wing grayish with piceous posterior margin. Hind wing venation ochraceous except castaneous proximal anal vein 2 and all of anal vein 3, castaneous spot on base of median and radius posterior veins, castaneous spot on base of anal vein 3. Basal plaga, anal cell 3 along anal vein 3 to curve, anal cell 2 along anal veins 2 and 3 to curve, and anal cell 1 along proximal anal vein 2 margined with gray, slight infuscation in anal cell 3 bordering gray.


Legs ochraceous, coxae, trochanters and femora striped with castaneous, fore tibiae proximally and distally, middle tibiae distally marked with castaneous, tibial spurs and tibial combs ochraceous with castaneous tips, fore and middle tarsi castaneous, hind tarsi ochraceous with castaneous distal pretarsus, pretarsal claws ochraceous at base with castaneous tips. Fore femora with primary spine adpressed to femur, almost as long as secondary spine, secondary spine with expanded distal base, longest, upright, and small tertiary spine parallel to secondary spine, primary and secondary spines with castaneous tips, tertiary spine castaneous. Legs radiating long white pile. Male meracanthus ochraceous with castaneous base, curved triangular extension, reaching over anteromedial opercular margin.


Male operculum ochraceous with castaneous spot on lateral base, lateral margin straight, broadly curved posterolateral margin, posterior margin transverse laterally, obtusely angled to rounded medial margin, anteromedial margin transverse to base, reaching to anterior of sternite II posteriorly, not meeting medially above elevation of sternite I, covered with short white pile at base, long golden pile radiating from operculum margin.


Abdominal tergites dark ochraceous except castaneous dorsolateral tergite 1, piceous lateral margin of tergite 1, and piceous anterior margin of tergite 2, tergites covered with white pile. Timbal cover absent, timbal completely exposed with seven long ribs. Male sternite I castaneous with ochraceous posterior, sternite II ochraceous with piceous anteromedial margin and auditory capsule, anterior trapezoidal extension over posteromedial tympanal cavity, sternite III with a pair of castaneous spots on either side of anterior margin, sternites IV–VIII dark ochraceous. Epipleurites dark ochraceous. Sternites and epipleurites radiating short golden pile, longer on sternites VII and VIII. Sternite VIII dark ochraceous, radiating long golden pile, denser ventromedially and posteriorly, V-shaped when viewed from posterior.


Male pygofer dark ochraceous with castaneous spot on dorsal beak tip, distal shoulder curving posterolaterad to terminal point, dorsal beak broadly triangular with rounded terminus longer than anal styles, pygofer with short golden pile dorsally and laterally. Upper pygofer lobe absent, pygofer basal lobes elongated, extending about half pygofer length with triangular apex, apex against lateral pygofer margin, adpressed to lateral pygofer, radiating short golden pile. Anal styles dark ochraceous radiating short golden pile, anal tube dark ochraceous. Median uncus lobe dark ochraceous, elongated, undivided, concave, with rounded posterolateral margin, distal margin sinuate, lateral uncus lobes reduced, lateral flange about half uncus length, covered with short golden pile. Aedeagus tubular with spatulate terminus, castaneous, restrained by ventromedial extension of uncus.

Female is unknown.

Measurements (mm).—N = 1 male. Length of body: 12.55; length of fore wing: 13.90; width of fore wing: 5.00; length of head: 1.95; width of head including eyes: 3.50; width of pronotum including suprahumeral plates: 4.30; width of mesonotum: 3.80.

Diagnosis.—The new species can be distinguished from the other Malagasiini  by the generic characters. Particularly diagnostic are the anterior extension of abdominal sternite II over the posterior tympanal cavity, the elongated pronotum, and the curved postclypeus and head.

Distribution.—The species is known only from the type specimen collected in Fianarantsoa Province, southeastern Madagascar.
