Description.

Female (Fig. 5 A View Figure 5 ) – Body length: 1.8–2.6 mm (x ̄ = 2.2 mm; n = 25; holotype = 2.6 mm). Color: Antenna color: red brown throughout, at most slightly darker distally than proximally. Head color: vertex and occiput dark red brown, mandibles red brown basally to darker red brown apically, rest of head red brown throughout. Mesosoma color: pronotum and propodeum red brown laterally to dark red brown medially, mesoscutum dark red brown, scutellum dark red brown, and mesopleuron dark red brown dorsally and ventrally but red brown medially. Wing membrane color: hyaline throughout. Wing vein color: light brown. Leg color: red brown throughout, except for apical tarsomere which is conspicuously darker. Metasoma color: red brown to dark red brown. Antennae (Fig. 5 B View Figure 5 ): Antennomere count: 13. F 1 length: 2.2 × as long as wide. F 2 length: 3.3 × as long as wide. F 2: F 1 length ratio: 1.4. Placodeal sensilla on F 2: absent; sensilla present only on F 3 and following antennomeres. Head (Fig. 5 C View Figure 5 ): Upper frons sculpture: reticulate. Gena posterolateral projection in anterior view: distinctly projecting past compound eyes. Facial radiating striae: distinct and complete, reaching compound eyes. Supraclypeal area sculpture: reticulate. Supraclypeal area projection: slightly projecting. OOL vs POL: OOL distinctly longer. OOL vs LOL: OOL greater than twice LOL. POL vs LOL: POL greater than twice LOL. LOL vs DLO: LOL longer. Vertex sculpture: reticulate throughout. Clypeus sculpture: reticulate. Mesosoma (Figs 5 D – F View Figure 5 ): Pronotum pilosity: densely pilose along anterior margin and with only sparse setae elsewhere. Pronotum excluding pronotal plate sculpture: reticulate. Pronotal plate sculpture: reticulate. Mesopleuron excluding speculum sculpture: reticulate with fine intermediate striae. Speculum sculpture: reticulate. Mesopleuron pilosity: ventral margin and mesopleural triangle densely pilose and bare elsewhere. Mesoscutum pilosity: sparsely pilose. Mesoscutum sculpture: reticulate. Apparent length of anterior parallel lines: reaching one third across mesoscutum. Morphology of anterior parallel lines: narrow, distinct throughout perceptible length. Apparent length of parapsidal grooves: reaching halfway across mesoscutum. Morphology of parapsidal grooves: narrow, distinct throughout perceptible length. Morphology of median mesoscutal impression: apparent as a shallow impression extending across most of mesoscutum. Notauli completeness: incomplete, distinct posteriorly to indistinct in anterior third. Morphology of notauli: appearing as wide indentations with sloping edges throughout distinct portions. Metapleural sulcus: meeting posterior mesopleuron at about one third of its height. Lateral propodeal carinae: distinct and subparallel. Metapleuron sculpture: reticulate. Mesoscutellar foveae distinction: distinct, relatively deep anteriorly to shallower and inconspicuously delimited posteriorly. Mesoscutellar foveae sculpture: reticulate. Mesoscutellar disc sculpture: rugose-reticulate, primarily reticulate, but with distinct rugose-reticulate sculpture seemingly restricted to outer margins. Mesoscutellar foveae length: long, reaching about one third across mesoscutellar disc. Mesoscutellar foveae shape: subquadrate, about as wide as long, separated by a narrow linear carina. Mesoscutellar disc shape: subcircular, about as wide as long. Wings: Marginal cell length: 3.1 × as long as wide. Fore wing distal fringe of marginal setae: absent. Metasoma: Punctation of metasomal terga: T 3 punctate only in posterior third and with T 4 and following punctate throughout.

Male (Fig. 5 G View Figure 5 ) – Same as female except for the following: Body length: 1.3–2.1 mm (x ̄ = 1.8; n = 25). Antennae: Antennomere count: 14. F 1 length: 2.3 × as long as wide. F 2 length: 3.2 × as long as wide. F 2: F 1 length ratio: 1.5. Placodeal sensilla on F 2: present. Wings: Fore wing distal fringe of marginal setae: present. Metasoma: Metasoma size: conspicuously smaller than in female.

Etymology.

Named for Lauren Ahlert, a biology teacher at Wayne Valley High School in Wayne, New Jersey, USA, who has served as a tremendous source of inspiration and passion for the author of this species.

Biology.

Antistrophus laurenae induces inconspicuous, externally imperceptible galls in stems of Silphium integrifolium (Fig. 5 H View Figure 5 ).

Distribution.

Material examined in this study reveals that this species occurs in Illinois, Iowa, and Wisconsin ( USA; see Suppl. material 1: table 1). A verified iNaturalist record (https://www.inaturalist.org/observations/136446787) also suggests that this species occurs in Mississippi. Known and potential distribution are summarized in Fig. 9 View Figure 9 .
