description: Trimeromicrus maculatus Gahan revived combination
Figs 206–215
Trimeromicrus maculatus Gahan, 1914: 162. Holotype (Ƥ, USNM, examined). Zatropis maculatus; Heydon & Bouček, 1992: 480.
Lyrcus maculatus; Bouček, 1993: 1250. Combination by implication through synonymy of Zatropis under Lyrcus by Bouček (1993: 1250).
Diagnosis. Metapleuron entirely sculptured and with anterior margin abutting posterior margin of mesopleuron on same level (Figs 212, 213). Flagellum (Fig. 210) with 3 basal ringlike articles lacking mps and 5 funicular articles with mps in both sexes. Fore wing disc with 1 to 2 irregular rows of distinctly longer admarginal than dorsal discal setae, and speculum extending to level usually about equal with middle of stigmal vein (Fig. 209). Head without malar depression (Fig. 211); parascrobal region usually with tiny bump or smooth and shiny spot adjacent to inner orbit at about mid height (Figs 210, 211: arrow), though absent from some smaller individuals. Head (Fig. 210) and mesosoma (Figs 206, 212) usually with distinctive pattern of bluish to green markings, including anteriorly on each mesoscutal lateral lobe and axilla, paramedial areas anteriorly on mesoscutal medial lobe, and medial area on scutellum, and with short, brownish, hairlike setae not contrasting with cuticle. Propodeum with plical carina and often additional carinae within nuchal furrow delimiting inverted Y-like margined adpetiolar strip, and without paraspiracular carina (Fig. 215). Both mandibles tridentate with two acute ventral teeth and dorsal truncation (Fig. 214).
Description. Female habitus: Fig. 208. Head (Fig. 210) and mesosoma (Figs 206, 212) of female dark except for variably distinct bluish to green markings, usually most conspicuously on mesonotum with paramedial spots anteriorly on mesoscutal medial lobe and anterior spot on each of mesoscutal lateral lobe, axilla and scutellum, though male sometimes more uniformly green to bluish (Fig. 207); head and mesosoma with brownish, hairlike setae. Eye bare or at least superficially bare with at most exceedingly short, sparse, inconspicuous setae. Mandibles tridentate, with two ventral teeth and dorsal, often slightly concave truncation (Fig. 214). Head in frontal view (Fig. 210) subcircular to slightly transverse-oval; antenna inserted obviously above lower margin of eyes near middle of face; tentorial pits not evident; clypeus very slightly incurved, vertically striate (Figs 211, 214); face almost uniformly meshlike reticulate, except usually for tiny bump or smoother and shinier spot adjacent to eye at about midheight (Figs 210, 211: arrow), though absent from some smaller individuals. Head in dorsal view (Fig. 206) abruptly declined immediately behind posterior ocelli, hence strongly transverse with vaulted vertex. Head in lateral view without malar depression, but with malar sulcus (Figs 211, 212); malar space about 0.6× height of eye. Antenna (Figs 208, 210) with scape extending to level of anterior ocellus; flagellum with 3 very strongly transverse basal flagellomeres without mps and with 5 quadrate to slightly transverse funiculars with mps; clava with apical clavomere uniformly conical without micropilose sensory region.
Pronotum with collar smoothly rounded into steeply angled collum (Figs 208, 212). Mesonotum (Fig. 206) meshlike reticulate; mesoscutum with incomplete notauli; scutellum without frenum, in lateral view apex rounded with posterior margin vertical to metanotum, not reflexed into distinct marginal rim (Fig. 212). Fore wing hyaline (Fig. 208); marginal vein not thickened and about 1.0–1.4× length of stigmal vein and subequal in length to postmarginal vein; stigma small, not distinctly capitate; costal cell comparatively narrow, without setae dorsally but ventrally with line of setae along length; basal cell, basal fold and mediocubital fold bare in female or basal cell apically/basal fold with 1–3 setae in male; disc ventrally with 1 to 2 irregular rows of long admarginal setae relative to discal setae; disc dorsally uniformly setose beyond speculum; speculum extending usually to level about equal with middle of stigmal vein (Fig. 209). Metapleuron completely sculptured and with anterior margin on same level as and abutting mesopleuron (Figs 212, 213). Metacoxa bare dorsobasally; metatibia with single tibial spur. Propodeum (Fig. 215) with short vertical carina posterolaterally on callus (cf. Fig. 103: arrow 2) within furrow differentiating slender supracoxal flange, but in dorsal view neither distinct or projecting denticle-like; with transverse-triangular adpetiolar strip variably distinctly delineated by inverted Y-shaped carinal complex; plicae variably distinct, but at least carinate posteriorly on either side of adpetiolar strip; plical region meshlike coriaceous-reticulate except for short longitudinal carinae extending posteriorly from anterior margin and usually with 1 or more short carinae within furrow between plical and median carina, but without any indication of costula or paraspiracular carina.
Gaster of female lanceolate (Fig. 208), about 1.2× combined length of head and mesosoma; Gt1 with posterior margin slightly emarginate; syntergum short; cercus with all setae of similar length; hypopygium extending at most about two-thirds length of gaster. Petiole smooth, shiny, and transverse.
Type information. Gahan (1914) did not specifically designate a holotype, simply stating that the species was described from many specimens and that the “ type ” was USNM catalogue number 18332. The USNM has a single female in the type collection labelled as “ Type No. 18332 U.S. N.M.”. Photographs of this specimen and its labels are available at http://www.chalcidtypes.com/. The general collection has one male labelled as “Allotype” and another 24 females and 17 males as “ Paratype ” under the same number. The putative holotype lacks its gaster, but some of the female paratypes are entire.

Hosts. A primary parasitoid of Curculionidae (Coleoptera) and seed-infesting species of Bruchophagus Ashmead (Hymenoptera: Eurytomidae), and a hyperparsitoid of the alfalfa gall midge, Asphondylia websteri Felt (Diptera: Cecidomyiidae) (Gibson et al. 2006). Based on material examined, new host records include— Chrysomelidae: Bruchus sp. Curculionidae: Endalus celatus Burke; Microlarinus lareynii (Jacquilin du Val); Sibinia setosa (LeConte) [= S. sulcatulus].
New plant associates (most apparently reared from seeds) include— Asteraceae: Helenium sp.; Helianthus sp.; Iva axilaris Pursh; Parthenium hysterophorus L. Brassicaceae: Brassica juncea (L.); Capsella bursa-pastoris (L.); Descurainia [= Sophia] sophia (L.); Erysimum cheiranthoides L.; Lesquerella douglasii S. Watson. Fabaceae: Acacia constricta Bentham, A. greggii A. Gray, A. neovernicosa Isely [= A. vernicosa]; Astragalus antiselli A. Gray, A. bisulcatus var. haydenianus (A. Gray), A.calycosus Torrey, A. douglasii (Torrey & A. Gray), A.lentiginosus Bentham, A. mollissimus Torrey, A. thurberi A. Gray, A. wootonii E. Sheldon; Lotus mearnsii (Britton); Mimosa aculeaticarpa var. biuncifera Ortega, M. borealis A. Gray, M. dysocarpa Bentham; Parkinsonia [= Cercidium] microphylla Torre]; Prosopis velutina Wooton. Marsileaceae: Marsilea mollis B.L. Robinson. Scrophulariaceae: Linaria vulgaris Miller. Solanaceae: Solanum rostranum Dunal.
Discussion. When Heydon and Bouček (1992) synonymized Trimeromicrus under Zatropis they noted that T. maculatus was unique among Zatropis species in having metallic blue-green patches on an otherwise dark mesonotum (Fig. 206). However, the spots are sometimes quite obscure, particularly in males, which are sometimes more uniformly green to bluish (Fig. 207), or in very small females. Furthermore, although the colour pattern is quite distinctive, it is not unique among Pteromalinae. I saw single females from Florida (CNC) and Oregon (UCDC) that represent two species with a mesonotal colour pattern (Fig. 205) similar to T. maculatus. I tentatively identify both species as Mesopolobus, though the female from Oregon has only two anelli and six funiculars. I have also seen some Neocatolaccus (Fig. 204) and Pteromalus with a similar colour pattern to T. maculatus, though typically the spots are not as distinct or as well defined.
An apparently unique feature of T. maculatus is a tiny, finely sculptured or shiny bump or at least spot on the ocular margin at about midheight of the eye (Figs 210, 211: arrow). Though this requires close observation and is not always evident in smaller specimens, it is an important secondary feature to assist recognition of individuals in which the normally distinctive colour pattern is not conspicuous and/or that have concealed mandibles. Furthermore, except often for the pedicel, the antenna, including the scape, is more or less uniformly orange to yellowish or, if the flagellum is darker orangey-brown, then at least the scape is light in colour, more yellowish (Fig. 210). This contrasts with Lyrcus species, which more commonly have the flagellum brown to whitish or at least the scape partly dark.
Heydon and Bouček (1992) did not state explicitly why they synonymized Trimeromicrus under Zatropis, but undoubtedly this was partly because of the conspicuously long and completely exposed admarginal setae (Fig. 209) similar to most Lyrcus species. However, as discussed previously, the distinctive setal pattern shared by Trimeromicrus and most Lyrcus is also shared with most Eurydinoteloides. The mandibular dentition of T. maculatus (Fig. 214), its propodeal sculpture pattern (Fig. 215), and possibly similar mesonotal colour patterns of some Mesopolobus (Fig. 205), may indicate T. maculatus is more closely related to species classified in Mesopolobus than to Lyrcus. Species of various genera are characterized by a single row of exposed admarginal setae and it is possible that the conspicuously long admarginal setae of T. maculatus is simply convergent to that of Oaxa and most Lyrcus and Eurydinoteloides.
Although monotypic genera serve little function within classifications for communicating relationships through nomenclature, they do serve to indicate taxa for which correct phylogenetic relationships are uncertain. For this reason, I resurrect Trimeromicrus from under synonymy with Lyrcus.
