Etymology.From the Latin word granulosus(having small grains) in reference to the granular sculpture of Gt6 of females.
Description.FEMALE (habitus: 87, 92). Head with lower face ( Fig. 88) and interantennal prominence green or scrobal depression blue to purple dorsally, with at most very slight reddish-coppery luster on lower face between torulus and malar sulcus; scrobal depression with scrobes green to extensively purple to reddish-violaceous, but at least lateral surface of depression ventrally near level of torulus blue to purple; gena variably extensively green but with variably large, contrasting reddish-violaceous to partly blue or purple region extending from gena to behind outer orbit ( Fig. 88); parascrobal region green to partly blue ventrally, but dorsally it and frons with reddish to darker violaceous lusters ( Fig. 93) to level behind posterior ocelli except variably widely green along inner orbits; vertex mostly green mesally to blue or purple laterally behind outer orbits; vertex and temples with dark setae. Head with interorbital distance about 0.27–0.29× head width; OOL: POL: LOL: MPOD = 0.43–0.53: 1.1–1.3: 1.1– 1.2: 1.0; distance between anterior ocellus and inner orbit about 1.3–1.4× MAOD; anterior ocellus about 1.1–1.3× MAOD from dorsal extent of scrobal depression, with sulcus extending from ventral margin to or within depression; frons ( Fig. 93) micropunctulate-reticulate compared to more reticulate-rugulose within ocellar triangle and on vertex. Antenna ( Fig. 88) dark brown except extreme apex of scape and clava at least ventrally pale; scape robust-subcylindrical, about 4.5–5.0× as long as medial width, and in lateral view apex of pedicel extending obviously beyond apical ventral margin when at right angle to scape ( Fig. 88). Mesoscutum not carinate mediolongitudinally; scutellar-axillar complex with axillae and scutellum similarly coarsely meshlike reticulate but reticulations on scutellum aligned more longitudinally. Front leg dark except tarsus sometimes paler, more orangish. Middle leg dark except trochantellus ventroapically and femur apically white; femur with denser tuft of long white setae in posterior half mesally ( Fig. 91); tibia with 4–6 pegs in straight or only slightly offset row. Hind leg mostly dark, but apex of coxa, trochanter and trochantellus white, femur dorsally within at most about apical third with more yellowish to yellowish-orange longitudinal region not quite extending to dorsoapical or apicolateral margins ( Fig. 90), and tibia with similar or more distinctly white region basally. Fore wing ( Figs 87, 92) with dark setae continuously through hyaline basal cell onto infuscate basal part of disc, without any whitish setae on basal or mediocubital folds ( Fig. 89); disc with hyaline region behind marginal vein tapered posterobasally, and if hyaline region along posterior margin apparent then this with dark setae; costal cell dorsally entirely setose along length, with several rows basally becoming less apically. Propodeum ( Fig. 94) appearing medially elongate, with ∩-like incurved posterior margin superficially distant from anterior margin, though anterior margin medially deeply incised with contiguous to subcontiguous margins extending almost to more finely sculptured and lighter colored, transversely lunate region along foramen, the plical region otherwise reticulaterugulose. FIGURES 87–95. Macreupelmus granulosus n. sp. 87, lateral habitus (holotype). 88, lateral head and antenna (2016-9). 89, medial part of fore wing (2016-8). 90 & 91, holotype: 90, metafemur; 91, mesofemur, posterior view. 92, dorsal habitus (2016- 9). 93 & 94, holotype: 93, frons; 94, propodeal plical region. 95, Gt6, posterolateral view (2016-10). Gaster mostly brown dorsally, but under some angles of light often with reddish-violaceous to blue or greenish lusters basally on Gt1, and Gt6, syntergum, and sometimes Gt 5 inwhole or in part, with slight, dark blue to purple luster; Gt6 granular ( Fig. 95). Ovipositor sheaths at most as long as metatibia ( Fig. 87).
Distribution(Map 1C). Ecuador, Peru.
Remarks.Females of M. granulosusand M. erwiniare the only two recognized species in the genus that have Gt6 granular ( Figs 86, 95), which likely is apomorphic relative to a reticulate Gt6. Except for fore wing color pattern, they are also very similar in other features, including having a superficially long propodeum but with the anteromedial margin actually deeply incised with subcontiguous to contiguous margins ( Figs 85, 94). Females of M. erwinidiffer by having the dark setae of the basal cell and disc separated by a hyaline region with white setae extending from the submarginal vein along the basal and mediocubital folds ( cf. Figs 76, 89). This feature might also be hypothesized as apomorphic based strictly on the principle of commonality, which would mean either the granular sculpture of Gt6 or the band of white setae evolved twice in Macreupelmus. However, females of some other species have some white setae on the mediocubital fold distal to the basal cell ( Figs 45, 54), which could be intermediate states between the more extensive regions of white setae characteristic of M. dromedariusand M. erwiniand the absence of any white setae in other species.
