Hermetia nana Lindner, 1935: 410. ST 1♁, 1♀ [MNRJ, destroyed], 1♀ [SMNS]: Brazil: São Paulo; ST 1♁ [SMNS]: Brazil: Rio de Janeiro. Syn. Fachin & Hauser (2022: 670).
Neotropical: Brazil (Distrito Federal*, Goiás *, Maranhão, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Rio de Janeiro, Rondônia, São Paulo), Guyana, Paraguay. [* New record]
Puparium: Length 10.7 mm (ranging from 8.2 to 15.6 mm); terrestrial, formed from the last instar (L6) larval skin (pupa exarata pharata), comprising head, three thoracic segments and eight abdominal segments (Figs. 10–13); the cuticle is dark-brown, covered with a browish pubescence; body soft, broad and dorsoventrally flattened; the integument more strongly hardened than in the larval stage, but preserving the larval features, especially the upper surface of the body, where the cuticle is impregnated by deposits of small hexagonal cells of calcium carbonate (Figs. 14–15, 21, 23); the larvae shared a similar shape and chaetotaxy with the pupae, except the presence of the emerging T-shaped suture (Fig. 14), expansible intersegmentary membrane, and pupal respiratory horns (ph).
Head. Moderately flattened and smoothly conical (Fig. 10–11, 16–17); mouthparts of the mandibular-maxillary complex (mm) forming a rigid and plane structure, almost as long as the labrum cavity in ventral view (Fig. 18); molar area (mo) conspicuous, maxillary palpus (mxp) with two developed sensilla (sl), basiconic sensilla of maxillary palpus (sb), coeloconic sensilla of maxillary palpus (sc) (Fig. 20); antenna (a) short, cylindrical and with a conical apex (Figs. 18–19), arising at the anterior part of the head; eye-prominence (ep) (Figs. 16–17), rounded, arising at the middle part of the head; chaetotaxy (Figs. 10–11, 16–19): 2 pairs of labral setae (Lb 1, Lb 2), 2 pairs of clypeofrontal setae (Cf 1, Cf 2), 1 pair of maxillary setae (mxs), 1 pair of lateral setae (L), 1 pair of dorsolateral setae (Dl), 1 pair of sublabral setae (Sl) heavily barbed, resembling a Christmas tree, 3 pairs of ventrolateral setae (Vl 1, Vl 2, Vl 3), and 3 pairs ventral setae (V 1, V 2, V 3).
Thorax. First segment shorter than the others (Figs. 10–11, 14–17); chaetotaxy: in dorsal view (Figs. 10, 14, 16), 2 rows of setae, 2 pairs of anterodorsal setae (Ad 1, Ad 2) and 3 pairs of dorsal setae (D 1, D 2, D 3), and 1 pair of dorsolateral setae (Dl); in ventral view (Figs. 11, 15, 17), 2 pairs of ventral setae, the inner pair (V 1) short, the outer pair (V 2) double, subequal in size and strongly barbed, with two accessory short setae (Fig. 21–22), and 1 pair of ventrolateral setae (Vl); anterior spiracle (as) strongly sclerotized, prominent, setae absent (Figs. 16–17). Second and third segments (Figs. 12–13, 15) with 1 row of setae, with 3 pairs of dorsal setae (D 1, D 2, D 3) in dorsal view and 2 pairs of ventral setae (V 1, V 2) in ventral view, the outer pair (V 2) double, strongly barbed and with variable sized branches; in lateral view 1 pair of dorsolateral setae (Dl), 1 pair of lateral setae (L) and 1 pair of ventrolateral setae (Vl).
Abdomen. Abdominal segments 1–7 (Figs. 12–13) with the same shape, and with 1 pair of dorsolateral inconspicuous respiratory pupal horns (ph); chaetotaxy (Figs. 12–13, 15): in dorsal view, a row of 3 pairs of dorsal setae (D 1, D 2, D 3); in ventral view, 3 pairs of ventral setae (V 1, V 2, V 3); in lateral view, 1 pair of dorsolateral setae (Dl), 1 pair of lateral setae (L), and 1 ventrolateral setae (Vl); ventromedial line of segment 6 with an ellipticalshaped sternal patch (spa), formed by an elevated and cylindrical cells with a conspicuous pores (Figs. 23–24); segment 8 (Figs. 12–13, 25–26) trapezoidal with anal slit short; chaetotaxy (Figs. 25–26): with 1 pair of dorsal setae (D), 5 pairs of ventral setae (V 1, V 2, V 3, V 4, V 5), 2 pairs of lateral setae (L 1, L 2), 1 pair of apical setae (Ap), 1 pair of subapical setae (Sa) around the posterior spiracular opening (pso).
Remarks. Despite a wide variation in body size, Hermetia larvae have very similar chaetotaxy and overall larval shape. Hermetia teevani differs from other known species of Hermetia by: (1) puparium ranging from 8.2 to 15.6 mm in length; (2) Sublabral setae (Sl) heavily barbed, resembling a Christmas tree (Fig. 18); (3) Ventral setae strongly barbed (V 1) (Figs. 17, 21); (4) Ventral setae (V 2) double with subequal branches, strongly barbed, except on the inner side (Figs. 17, 21–22); (5) Ventral setae (V 2) slightly longer than ventral setae (V 1) (Figs. 17, 21).
