TERATOGNATHA MODESTA OGLOBLIN

Figures 39, 40

DIAGNOSIS: See Diagnosis of Chilimalopsis parvula , above.

Head: Epipharynx with pair of dense patches of elongate, mesally directed spicules; mandibular corium with fine spicules. Antennal papilla large, projecting, cone shaped, sharply pointed, slightly longer than basal diameter, and slightly longer than maxillary palpus. Mandible as seen in aboral view with upper and lower silhouettes tapering rapidly to narrowest area in vicinity of multispined cusp and then expanding outward before ending in two apical teeth; these teeth with coarsely serrated edges; serrations so long between apical teeth that they appear to make single truncated mandibular apex on unworn mandible; on worn mandible mandibular apex appearing subtruncate with crenulated or scalloped edges; dorsal apical mandibular edge with several large teeth but in cuspal area dorsal edge forming row of approximately 10 moderately long, regularly spaced teeth; lower edge of cusp bordered by approximately 5–6 very large teeth and one or more smaller teeth; planar surface of cusp pebbled with smaller teeth; outer mandibular surface with single seta toward base. Salivary opening with weakly projecting transverse lips, width less than one-half distance between labial palpi. Hypopharynx faintly curved medially with entire surface spiculate, with pair of lobes; hypopharyngeal groove present, distinct.

Body: Subatrium moderately short, consisting of only about seven chambers, clearly decreasing in outside diameter from body surface inward. Male with small transverse scar on apex of protuberance of abdominal segment 9; female characters unknown.

MATERIAL STUDIED: Two predefecating larvae: Argentina: Salta Province: 6 km SW of Pichanal, XI-11-1993 (J.G. Rozen, A. Roig) .

REMARKS: Nesting biology of this species is described below.
