Diagnosis
Body shape rounded, TL = 4.35–4.86 mm (4.61 mm, n = 2), almost circular; large pentagonal mentum with subequal sides, nearly rounded outline; apex of prosternal process conspicuously wider than procoxae (> 1.5× procoxal width); metendosternite welldeveloped, laminae present, anterior tendons conspicuously widened in males; colour pattern full yellowish to reddish-brown, antennomeres VIII–XI blackish. Genitalia with penile flagellum elongate, approximately 2.09× the length of penis; flagellar head resembling a ‘fish-like’ structure. Vaginal process present, blunt swelling and elongate to the level of gonostyli.
Distribution
North and Southeast Brazil, Colombia, Costa Rica, Guiana, French Guiana, Panama, Suriname ( Alvarenga 1994) ( Figure 55 View Figure 55 ).
Nomenclature
The species synonymised here under Mycomystes coccineus ( Mycotretus unicolor and Mycotretus sanguinosus ) are fully yellowish to reddish in colour, and are oval (almost circular) in body shape. Specimens from North and Southeast Brazil were dissected and no morphological difference was observed in their body structures, even in the penile flagellum.
Remarks
The primary type of M. coccineus is probably housed in the Brême collection, MRSN (Torino). The drawers of the collection were photographed and the specimen mentioned here is labelled as ‘Lacordaire [handwritten]’ and is kept in drawer ‘15’, in which it is handwritten ‘Erotyliens – Engidiformes 1 H–16’. Unfortunately, that information was observed after visiting the museum. As we did not have dorsal and ventral images of the specimen, we prefer not to designate the lectotype of M. coccineus here.
Curran (1941) pointed out that M. sanguinosus would be a possible synonymous of M. coccineus , although stating his act as doubtful (‘?’). However, subsequent authors ( Blackwelder 1945; Alvarenga 1994) did not recognised Curran’s synonymy of M. sanguinosus with M. coccineus . Curran examined only specimens from ‘Kartabo’ ( Guyana) with no information on individuals of different localities. Therefore, we do not recognise the validity of the Curran’s act and propose the new synonymy of M. sanguinosus with M. coccineus in the present work.
