Dinoptera collaris
Classification
Diagnostic Features of Larvae
- Mature larva. Length up to 12 mm; maximum breadth (at prothorax) 3 mm. Form stout, very strongly depressed and parallel-sided. Head slightly narrower than prothorax, very strongly depressed and transverse (maximum he.ad-width 2.2 mm), with sides broadly angulate; strongly sclerotized, completely ferruginous, and bearing several extremely long stout setae. Frons divided by a distinct transverse line; six rather deep depressions present. Six epistomal setae present. Antenna minute, two-segmented, the second segment bearing several spine-like processes. Mandible very slender, at least three times as long as basal width, and bearing two stout setae on outer face. Six ocelli present, one pair being placed ventrally; lens strongly protuberant; pigmented spot very distinct Gular sutures indiscernible but a ventral white cleavage line present. Maxilla with third palpal segment longer than second; lobe slender, cylindrical. Prothorax depressed, more than three times as long as broad and with a pair of sublateral, dark brown depressions. Eusternum rugose and glabrous. Mesonotum and metanotum glabrous except for stout lateral setae. Abdomen very strongly depressed, with dorsal and ventral ampullae on segments one to seven. Each dorsal ampulla tuberculate, glabrous and shining. Pleural tubercle very strongly protuberant and bearing five long setae. Ninth segment triangular, with a pair of sublateral, longitudinal impressions and bearing numerous long, stout, marginal setae. Tenth segment ventral, in the form of a pseudopod. Legs strongly sclerotized, extremely long and visible from above; unguiculus with ventral margin concave as far as basal third, which is parallel-sided (as in Judolia). Spiracles large, with peritreme round; marginal chambers in the form of a characteristic crescent (as in Judolia). This larva shows strong affinities towards the curious larva of Apiocephalus.
