29. E. iangauldi sp. nov. ( Fig 10i )

This species is closely related to E. monticola Gauld , a widespread species whose range extends from Mexico to Argentina but without records in the Caribbean islands. The form of central sclerite in E. iangauldi specimens is like the E. monticola “I morph” ( Gauld, 1988: 234). However, the Cuban species has a completely different colour pattern as well as other structural differences (e.g. scutellum). Gauld has also seen the specimens and concurs it is clearly a new species.

DESCRIPTION. HEAD: Mandibles moderately long, proximally with a well­developed proximoventral lobe, distally weakly narrowed, apically twisted about 50°; upper mandibular tooth cylindrical, 1.6 times as long as the lower tooth; outer mandibular surface finely pubescent, more or less flat. Labrum 0.25 times as long as broad; malar space 0.25 times as long as basal mandibular width. Clypeus in profile weakly convex, margin slightly sharp; clypeus in front view 1.3 times as broad as long. Lower face 0.62 times as broad as long, finely punctate. Head in dorsal view with genae evenly constricted behind eyes; posterior ocellus contiguous with eye; FI = 69–70 %; occipital carina mediodorsally complete, ventrally curved to join hypostomal carina about 0.9 times the basal mandibular width away from mandible. Antenna slender, with at least 47 flagellar segments (both specimens had broken antenna); 20th segment 2.3 times as long as broad. MESOSOMA: Mesoscutum rather weakly polished, with fine punctures, in profile evenly rounded; notauli vestigial. Mesopleuron polished and punctate; epicnemial carina inclined towards anterior margin of pleuron, with upper end evanescent and lower corner somewhat produced as a weak tubercle. Scutellum in profile weakly convex, laterally carinate for almost all of its length; scutellum in dorsal view 1.2 times as long as anteriorly broad, with fine puntures. Metapleuron strongly convex, diagonally striate with stronger diagonal rugae posterodorsally, anteroventral region punctate; submetapleural carinae quite broad anteriorly; posterior transverse carina of mesosternum complete and strong. Propodeum in profile fairly abruptly declivous; anterior transverse carina complete, posterior transverse carina absent; anterior area long and somewhat striate centrally; spiracular area short, finely punctate; posterior area reticulate to somewhat concentrically rugose, with traces of lateral crests an a slight median longitudinal wrinkle; lateral longitudinal carina complete and joined to spiracular margin by a short carina. Fore wing length 15–16 mm; AI = 0.90– 0.98; CI = 0.32–0.53; ICI = 0.46–0.57; SDI = 1.24–1.41; cu­a proximal to the base of Rs&M by 0.35 times its own length; marginal cell proximally with a slight glabrous area; first subdiscal cell with upper half broadly hirsute (specially distally), lower half almost completely glabrous, except lower distal corner. Hind wing with 6–7 hamuli on R 1; 1st abscissa of Rs weakly sinuous, 2nd abscissa almost straight. Fore leg with tibia slightly flattened, with numerous slender spines on outer surface. Middle leg with longer tibial spur 1.45 times length of the shorter. Hind leg with coxa in profile 1.65 times as long as deep; trochantellus dorsally less than 0.1 times as long as broad; 4th segment of tarsus missing in both specimens; claws of male moderately long, distally abruptly curved, with close but short pectination. METASOMA: Metasoma slender; tergite 2 in profile more than 5.5 times as long as posteriorly deep; thyridia ovalelliptical and separated from anterior margin of tergite for more than 4 times its own length. Male with sternites 6–9 bearing long dense erect hairs; gonosquama elongate and distally rounded. COLOUR: Orange brown, with metasoma from tergite 6 onwards blackish brown; head yellow, with interocellar area brown and antenna dark brown; wings with weak infumate tips and pterostigma blackish.

ETYMOLOGY: I dedicate this species in honor of Dr. Ian Gauld (BMNH), for all of his support to this research in such a ways to numerous to mention.
