According to the known collecting data, M. conicara is distributed in the hot tropical and subtropical regions of southern Yunnan Province, China. The species is rare, forages on the ground and in soil, and possibly nests in the soil. Specimens have been collected from various forest habitats. (Xu and Liu 2012)

Identification

According to the character of petiolar node, this new species is close to Myopias levigata from Papua New Guinea, but in profile view, subpetiolar process has a pair of posteriorly pointed small denticles at posteroventral corner; in dorsal view, lateral sides of petiolar node convex, anterolateral corners rounded. The new species is also close to Myopias loriai from Papua New Guinea, but in profile view, subpetiolar process has a triangular posteroventrally pointed denticle at anteroventral corner, and has a pair of small posteriorly pointed denticles at posteroventral corner; in dorsal view, petiolar node about as long as broad.

Description

Worker

Holotype: TL 7.5, HL 1.50, HW 1.40, CI 93, SL 1.33, SI 96, PW 1.00, AL 2.20, ED 0.25, ML 1.35, MI 90, PNL 0.37. Head slightly longer than broad, broadest in front, narrowed posteriorly; in full face view, occipital margin nearly straight, occipital corners roundly prominent. Eyes placed on lateral sides, close to the bases of mandibles. Mandibles long and slender, slightly curved inward; inner margin with a blunt tooth near the center; masticatory margin narrow, oblique and slightly concave, with a very small denticle at basal 1/3, apical tooth acute, basal tooth triangular. Middle part of clypeus triangular, anterior margin roundly concave, anterolateral corners protruding and dentiform. Frontal lobes large, laterally expanded. Frontal furrow reached to midline of head. Antennal scapes surpass occipital corners by about 1/8 of its length; flagella incrassate towards apex, apical segment slightly longer than the preceding 2 segments combined. Ventral face of head with a conical tubercle in the middle and close to the anterior margin. In profile view, dorsum of alitrunk at the same level, promesonotal suture distinct and depressed, metanotal groove slightly depressed. Mesonotum short, crescent in dorsal view. Dorsum of propodeum slightly convex, rounded into declivity, the latter nearly truncate, about as long as dorsum. In profile view, petiolar node quadrate, slightly higher than long; anterior face very weakly concave; posterior face truncate, each side with a vertical narrow depression close to the lateral margin; dorsal face roundly convex, anterodorsal angle and posterodorsal angle rounded , at the same height. In dorsal view, petiolar node about as long as broad, narrowing forwards, anterior margin slightly convex, anterolateral corners rounded, posterior margin straight. Subpetiolar process with a posteroventrally pointed triangular denticle at anteroventral corner, and with a pair of small posteriorly pointed denticles at posteroventral corner. Anterior face of gaster truncate, constriction between the basal two segments distinct. Mandibles sparsely punctate , interspace smooth and shining. Head with abundant moderate large punctures , distance between punctures about equal to diameter of one puncture, interspace smooth and shining; punctures on central dorsum of head sparse. Dorsum of alitrunk, dorsum of petiolar node and first gastral segment with sparse large, elliptic punctures, interspace finely longitudinally rugulose, less shining; a longitudinal central strip on dorsa of pronotum and mesonotum without punctures; lateral sides of pronotum, and of petiolar node sparsely punctate; lateral sides of alitrunk finely longitudinally rugulose, opaque; declivity and posterior face of petiolar node surperficially transversely rugulose, less shining. Gastral segments 2-6 smooth and shining, but anterior half of 2nd segment sparsely punctate. Head and body with abundant erect or suberect hairs and abundant decumbent pubescences. Antenna1 scapes with sparse suberect hairs and dense decumbent pubescences ; hind tibiae with sparse decumbent hairs and dense depressed pubescences. Body in colour black; mandibles, antennae, legs, and apex of gaster reddish brown; hairs and pubescences light yellow.

Queen

Paratype dealate females: TL 8.5-9.4, HL 1.55-1.70, HW 1.40-1.65, CI 90-97, SL 1.30-1.50, SI 91-13, PW 1.23-1.33, AL 2.63-2.88, ED 0.33-0.38, ML 1.30-1.50, MI 84-88, PNL 0.80 (n=2). Similar to holotype, but body larger; head with 3 ocelli, conic tubercle on ventral face of head large and low; mesonotum large, with tegulae, transverse sutures and longitudinal furrows; dorsum of propodeum shorter than declivity.
