description: Apochrysa generic characteristics
Based on the A. voeltzkowi specimen described here (Figs 3, 4, 7, 8,), along with the description and illustrations of the third instar A. matsumurae by Tsukaguchi (1995: 139, 142, Figs 106r–106u), the following combination of larval features appears to characterize the genus Apochrysa:
General Characteristics (all instars)
Body: elongate, abdomen slightly thickened, cream-colored, with no or few markings.
Debris packet: large, dense (both known species reported to carry flocculence of Sternorrhyncha) (photo by P. Duelli in Aspock & Aspöck 2007, photo by Yusei Hara in Tauber et al. 2014).
Eye: Anterior two stemmata large; posterior four slightly reduced in size (A. voeltzkowi: Figs 3, 7 here; not reported for A. matsumurae).
Mandibles: slender, elongate, ~1.5x length of head capsule.
Antenna: flagellum long (approximately 0.75x (L1) to 0.45x (L3) length of pedicel).
Cranial setation: All primary cranial setae present, smooth and acute, including S12 and three frontoclypeal setae; Vx setae in longitudinal row beneath cervical membrane.
Thorax: Lateral tubercles (LTs) well developed, but not large; prothoracic LTs not reaching the region of the head.
Thoracic setation: All setae smooth; setae (LS) on lateral tubercles elongate, tapering to very fine, acute or lightly hooked tip; dorsal setae shorter, less tapered, with acute tips. Mesonotum, metanotum each with two (L1) or three (L3) transverse rows of setae.
Abdomen: A1–A7 with laterodorsal tubercles (LDTs) bearing robust setae.
Semaphoront A (first instar) [based on A. voeltzkowi only]
Thoracic lateral tubercles: Prothoracic LTs each with two LS; mesothoracic and metathoracic LTs each with three LS.
Thoracic setation: Prothorax with primary setae S1, S3, S4, S5, S1Sc1, and S2Sc1 present (S2, S1Sc2 apparently absent). Mesothorax with primary setae S1Sc1, S2Sc1 present, SSp absent; posterior region with transverse row of four setae. Metathorax with primary setae S1Sc1, S2Sc1, S3Sc1 present; posterior region with transverse row of four long setae arising from robust chalazae.
Abdominal tubercles: A1 with small LT bearing single long LS; LDT with single elongate, slightly hooked LDS and one very small lateral seta. A2–A7 with well developed LTs, each bearing two elongate LS.
Abdominal setation: Each segment with anterior transverse row of four acutely tipped or slightly hooked setae, two submedian setae (SMS) arising from large chalazae between LDTs.
Semaphoront B (third instar)
Head: Secondary setae present in patch near S1, S3, S11.
Thorax: LTs broadly cylindrical, tapered distally (especially on T2 and T3), longer than those on abdomen, extending dorsolaterally (prothorax) or laterally (mesothorax, metathorax); prothoracic LTs slightly smaller than those on mesothorax or metathorax.
Thoracic sclerites: Prothoracic primary sclerites (Sc1, Sc2) large, rounded, associated setae not distinguished; mesothoracic sclerites Sc2, Sc3 distinct, with associated setae S1Sc2, S2Sc2, and S1Sc3 present; metathoracic sclerite Sc3 distinct, with associated seta S1Sc3 present.
Thoracic setation: Setae on LTs numerous, elongate; dorsal setae numerous, smooth, short to medium-length, tips acute; most primary setae not distinguishable; posterior subsegment of metathorax with transverse row of ~12–15 slightly more robust setae than elsewhere on thorax.
Abdomen: LTs papilliform (A2–A5, A8) to slightly cylindrical (A6–A7); well sclerotized LDTs (A1–A7), each with two to four elongate setae and several shorter setae.
Abdominal setation: LS, LDS elongate but shorter than those on thoracic tuberlces, with tips weakly hooked or acute; submedian setae (SMS) of A1–A6 moderately hooked; dorsal setae of A7–A10 with acute tips; SMS (A2–A6) numerous, in three transverse rows.
