Colophorina Capener

Colophorina Capener, 1973: 41 ; Li, 2011: 506. Type-species: Colophorina cassiae Capener, 1973 , by monotypy.

Diagnosis. Adult. Vertex subrectangular, base straight, dorsally completely flattened including area adjacent to median ocellus, bearing distinct anteorbital tubercle; separated from genae by transverse suture; genal processes lying in the same plane as vertex, flattened dorsally, usually irregularly truncate apically. Antenna shorter than twice head width; segment 3 longest. Rostrum short, hardly visible in profile. Metatibia lacking genual spine, with 4–6 sclerotised, relatively evenly spaced apical spurs. Forewing rhomboidal, subrectangular or broadly, evenly rounded apically, usually with flattened, slightly widened vein C+Sc. Hindwing with vein M+Cu. Male proctiger unipartite, tubular. Male subgenital plate hemisphaerical. Paramere lamellar, simple. Distal segment of aedeagus simple, with weak oval apical dilatation; sclerotised end tube of ductus ejaculatorius short and thick, almost straight. Female terminalia cuneate, short; circumanal ring cruciform. Fifth instar immature. Antenna 8-segmented. Capitate setae absent. Additional pore fields present as 1+1 convoluted loops. Following numbers of marginal sectasetae present: hindwing pads 0+0 or 1+1, abdomen 3+3 or 4+4.

Description of adults and immatures by Capener (1973) and Li (2011).

Egg. Oblong oval, slightly curved, 3–4 times as long as wide; irregularly narrowing at apex which is subacute ( Fig. 23 ). Surface with cellular microsculpture.

Comments. Colophorina , as diagnosed above, is a pantropical genus closest related to Euryconus Aulmann. Species of both share the same head structure and are associated with Leguminosae. Colophorina includes 10 de- scribed species ( Li 2011; Ouvrard 2019) but several species currently misplaced in Euphalerus Schwarz also belong here (D. Burckhardt, unpublished data). On the other hand, the only Neotropical member, C. favis ( Brown & Hodkinson, 1988) , does not conform with the diagnosis provided above. It is not congeneric with C. cassiae , the type species of the Colophorina , but with E. edentalis Li , the type species of Epiacizzia Li (D. Burckhardt, unpublished data) to which it is transferred here as Epiacizzia favis ( Brown & Hodkinson, 1988) , comb. nov. from Euphalerus .

Here we add four new species from Brazil which are morphologically similar and probably constitute a monophyletic group. They differ from other described species, all from the Old World, in the slightly convex, apically broadly rounded forewings and the host association with Copaifera spp. The species are mostly characterised by the shape of the genal processes and the forewing pattern. The morphology of the male and female terminalia, including the parameres and the distal portion of the aedeagus, is very homogeneous and useful only to a limited degree for separating species. A single teneral ♀ from Brazil: AM, Novo Airão, Parque Nacional de Anavilhanas, -2.5366/6217 -60.8327/9559, 20– 30 m, 18–20.iv.2014, Amazonas inudation forest (D. Burckhardt & D.L. Queiroz) #128 (NHMB, 70% ethanol) probably represents another undescribed species but more material is required for a formal description.
