(Figs 14–19)
Comments and diagnosis. Symmorphus centralis sp. nov. (Figs 14, 15) may be identified mainly by the long T1 (Fig. 18) compared to the other species of the genus, except for S. chiriquiensis (Fig. 20) that has T1 even longer and more slender (Fig. 21). Besides that, the posterior face of the propodeum is strongly concave (Fig. 15); the pubescence is short and there is coarse punctation homogeneously distributed on T2 (Fig. 19), while S. chiriquiensis has incipient punctures on T2 (Fig. 22).
Description. Holotype, ♀. Color. Body black; yellow marks as follows: central surface of mandibles; small spots on each side of upper half of clypeus; square spot right above inter-antennal region; small spot on upper half of gena; almost entire scape and pedicel; broad spots on antero-dorsal surface of pronotum; rounded mark on upper half of mesepisternum; yellow-translucent stripe along external margin of tegula; broad stripe on posterior region of scutellum, interrupted mesally; marks on femora, tibiae and tarsi; stripe on apex of T2-T3 and S2; other segments with brownish translucent stripe on apex. Wings yellowish; costal, medial and marginal cells slightly darkened. Pterostigma and veins brownish.
Pubescence. Golden pubescence on head. Short pubescence on basal region of clypeus, becoming longer towards apex; short pubescence on frons, vertex and gena; longer on occipital region. Golden and short pubescence (shorter than on frons) on mesosoma, except on posterior face of propodeum where it is longer. Terga covered with short and golden pubescence, except on basal region of T1 where it is whitish and slightly longer and on apex where there is no evident pubescence. S1 covered with long and erect bristles. Other sterna covered with short and whitish pubescence. T2-T6 and S2-S6 with some longer and erect bristles on apex.
Sculpture. Coarse and sparse punctures on clypeus. Frons, vertex and gena with coarse and denser punctation. Anterior surface of pronotum with coarse and sparse punctures mostly on central region. Dorsal surface of pronotum with coarse and sparse punctures, becoming denser on lateral surface; coarse and sparse (sparser than any other sclerite of mesosoma) punctures on mesepisternum; scutellum with coarse punctures, very dense mesally and sparser laterally; mesoscutum, metanotum, posterior face and posterior half of lateral face of propodeum with coarse and dense punctation; anterior half of lateral face of propodeum covered with punctures, dense next to margin of mesepisternum. Dorsal surface of T1 with coarse and dense punctation, becoming slightly sparser on lateral surface. S1 with very coarse, deep and dense punctures, forming carinae between punctures. T2 and S2 with coarser (but weaker than on mesosoma and T1) and sparser punctation, becoming stronger and denser towards apex; T3-T5 and S2-S5 with smooth and sparser punctures. T6 and S6 without evident punctures.
Clypeus convex, wider than long, with concave apex forming two apical projections (Fig. 16); each apical projection with well developed carina; inter-antennal region rounded, wider than antennal socket, with brief longitudinal carina next to basal suture of clypeus; upper half of gena broader than distance between inner and external margin at ocular sinus level (Fig. 17); occipital carina complete, more developed dorsally and strongly angled at midpoint of gena; pronotal carina complete and well developed, strongly angled on humeral region; mesoscutum longer than wide, with notauli; posterior projection of tegula pointed, not surpassing apex of parategula; parategula flattened laterally; posterior face of propodeum strongly concave, with deep furrow on apical region; propodeal valvula not free posteriorly, fused to submarginal carina; longitudinal carina along middle section of posterior face of propodeum, strongly developed basally and becoming superficial towards apex; propodeal orifice narrowly acute dorsally. T1 short and broad apically, less than twice longer than wide (Fig. 17); transverse carina on dorsal surface of T1 not reaching lateral surface; median longitudinal furrow on apex of T1; T2 longer than wide (Fig. 19) with apical lamella that becomes rudimentary towards lateral region;
Male. Unknown.
Type material. Holotype, ♀, ‘S. Rosa Park, Guan. \ C. Rica 6 Jun 77 \ D. H. Janzen \ Dry Hill’.
Etymology. The epithet indicates the Central American locality of the species.
Distribution. Costa Rica (Guanacaste).
