A review of neococcid scale insects (Hemiptera: Sternorrhyncha: Coccomorpha) based on the morphology of the adult males Author Hodgson, Chris text Zootaxa 2020 2020-04-16 4765 1 1 264 journal article 22494 10.11646/zootaxa.4765.1.1 8af5a092-f062-48c7-8d7c-f96ae6282bfa 1175-5334 3774174 urn:lsid:zoobank.org:pub:C442D94C-0EB4-4509-B762-913707214819 Tectococcus Hempel 1900 Tectococcus Hempel 1900 , 379, 406. Type species: Tectococcus ovatus Hempel by monotypy and original designation. Introduction. Tectococcus currently includes a single species from Brazil , T. ovatus , which induces circular galls on the young leaves and buds of mainly Psidium cattleianum (Myrtaceae) but also on Psidium variabile [spelt wrong in García Morales et al . (2019) ] and Daphnopsis racemose (Thymelaeaceae) ( Vitorino et al . 2000 ). In addition, Hoy (1963) gives Aplidium variabile (Polyclinidae) as a host plant but no such name appears to exist. Nymphs may also establish galls on young branches and even on the developing fruit. Vitorino et al . (2000) state that reproduction is facultatively parthenogenetic, although males appear in late Spring and sometimes in late Autumn. There are probably 2 generations a year, one in May and June (sometimes into July), and another in January and February ( Vitorino et al . 2000 ). The adult female and adult male were described by Viterino et al . (2000) and the adult female, firstinstar nymph and adult male were redescribed by Hodgson and Miller (2010) . Generic diagnosis based on adult male morphology ( Fig. 40 ). Body : abdomen attenuated, about 2/3 rd of body length, tapering to a narrow penial sheath; setae few, perhaps mainly hs. Head: simple pores present ; ocular sclerite with a few reticulations; dorsal mid-cranial ridge absent; preocular ridge absent; antennae 8 segmented ; flagellar segments with hs and fs; capitate setae present on apical four segments . Thorax: scutal setae present laterally; scutellum with scutellar setae; basisternal setae present; metasternum with few setae; metaprecoxal ridge absent; postmetaspiracular setae possibly absent; tibia and tarsus setose, most setae spur-like; tarsi 2 segmented; claw digitules capitate but one narrower than other ; claws elongate, with a denticle. Abdomen: elongate, narrowing to a narrow penial sheath; glandular pouches absent on segment VIII; setae absent on segment IX but with 2 pairs near apex of style; style narrow, becoming pointed posteriorly. FIGURE 40. Tectococcus ovatus Hempel. Macropterous male. ( Eriococcidae, Gondwanan group). Where X=pores on head. Comment. The adult male of T. ovatus is easily separated from other known adult male eriococcids from the Neotropics by the following combination of characters: (i) abdomen much elongated, narrowing to a narrow penial sheath; (ii) body setae very few, all hs; (iii) antennae 8 segmented; (iv) capitate setae present on apical 4 antennal segments, and (v) pores present on head. The elongate abdomen is somewhat similar to those found in various Australian genera – see the above key for genera in the Gondwanan group for differences.
