Adults. Female (Fig. 204) with 2 pairs and male (Fig. 206) with 4 pairs of wax plates on abdomen. Upper and lower compound eyes joined by three ommatidia. Antennae 7 segmented in both sexes (Figs 223, 224), with an elongate third segment with two primary round sensoria near the apex, fifth and seventh segments each with 1 round primary sensorium located at apex on fifth and at about two thirds of its length on seventh, and third, sixth, and seventh segments with an elongated rod-like sensorium each. Hind tibiae (Figs 225, 228) with a tibial comb of 12 or 13 setae in male, 12–14 setae in female; metatibial brush with 2 setae in male, 3 setae in female. Mesotibial brushes with 2 and 3 setae in male, 3 setae in female. Female cement gland not discernible (Fig. 220). Male parameres very narrow along distal fourth, ending on a single long apical tooth, lacking subapical teeth (Fig. 222).
Nymphal instars 1–3. All with a central longitudinal rachis along abdomen (Figs 255–257). First instar (Fig. 255): with 6 or 7 pairs of long submarginal setae along sides of cephalothorax and 1 pair at level of VO. VO oval, wider than long, with anterior margin straight; operculum oval occupying most of VO; lingula head bulbous and covered with microsetae; other characters not discernible. Second and third instars (Figs 256, 257): same as first except for absence of long submarginal setae, VO located on a promontory, and operculum subcordate.

Similar species. Tetralicia cecropiae, T. lantanae, and T. oblanceolata share an oblanceolate puparium and VO located on a pronounced promontory.
Diagnosis. Puparium can be distinguished from other oblanceolate species in California (characters for T. lantanae and T. oblanceolata in square brackets) by its TMS not reaching apparent margin (Figs 97, 98) [reaching apparent margin; Figs 134, 135, 168 –170], lacking large tubercles on submedian abdomen (Figs 97, 99) [with large tubercles at least along anterior margin of abdominal segments; Figs 134, 135, 137, 169], and mediolateral abdominal depressions conspicuous and lined with small granulations (Figs 97, 99) [depressions inconspicuous; Figs 134, 135, 137, 169]. It can be recognized from T. cecropiae (characters for T. cecropiae in square brackets, based on pictures of syntypes at USNM kindly sent by G. Evans and I. Stocks) by TMS extending halfway onto submargin (Figs 97, 98) [ending at submargin without extending onto it], dorsal submargin with granulations turning into transverse rows of paired crenulations externally [dorsal submargin lacking granulations or crenulations], spinulae present along medial bases of legs but absent from legs' surfaces (Figs 100, 101) [spinulae entirely covering legs], absence of a sclerotized arch on A7 (Figs 97, 103) [with a sclerotized arch on posterior margin of A7], setae on T2, T3, and on dorsum of A8 shorter (seta length/VO length T2: 0.3–0.5; T3: 0.4–0.6, A8: 0.3–0.5) and caudal setae longer (caudal seta/VO length 2.3–3.1) compared to length of VO [longer and shorter respectively; seta length/VO length T2: 0.8, T3: 1.0, A8: 0.7, caudal: 1.4], and VO located on a less pronounced promontory [on a higher promontory]). Bondar (1923) described and illustrated the lateral wax ring on true margin as extending dorsally along submargin and beyond in T. cecropiae; in our dry mounted specimens of T. guajavae it only extends partially along ventral most section of submargin (Fig. 12).
Among the known adults of Tetralicia from California, T. abnormis has two smoky spots near midlength and three on distal portion of forewings (Quaintance 1900: 18), whereas in addition to those markings T. lantanae has also a basal spot, and T. nigrans has wings 'somewhat dusky at distal ends' (Bemis 1904: 523). The color of live adults of T. guajavae is unknown, and that of T. hoelmeri was not described (Polaszek & Gill 2011), and since the faint markings of species with marked forewings are usually not discernible in slide-mounted specimens (pers. obs.), it is not possible to know if the forewings in these two species are unmarked (like they would appear to be in slide-mounted specimens) or marked. Tetralicia abnormis and T. guajavae appear to be the smallest and T. hoelmeri the largest (Table 2). The upper and lower sections of the compound eyes are connected by three ommatidia in T. guajavae and two to three ommatidia in T. lantanae (Figs 247, 248), but only by one in T. hoelmeri (Figs 235, 236). The adult male of T. guajavae can also be recognized from those of T. lantanae and T. hoelmeri by parameres ending on a single slightly curved long distal tooth, as long as about a fourth of parameres length, lacking subapical teeth (Fig. 222). In T. hoelmeri the distal tooth is about as long as a sixth of parameres length and is more markedly curved medially (Fig. 234), whereas in T. lantanae it is as long as a ninth of parameres length and it is preceded by three subapical teeth (Fig. 246). Both T. guajavae and T. lantanae have metatibial and mesotibial brushes of 2 or 3 setae, but these are not defined in T. hoelmeri. The female of T. hoelmeri (Fig. 232) differs further from those of T. guajavae (Fig. 220) and T. lantanae (Fig. 243) by its much longer ovipositor (see Table 2). Based on the absence of tibial brushes and the long ovipositor, the adults of T. hoelmeri resemble those of T. ericae (Valencia & Evans 2024: 208, fig. 3). Bemis' (1904) description of the adults of T. nigrans was very brief, but their size is comparable to those of T. lantanae (see Table 2), from which they differ by the wing pattern as described above.
First instar nymphs of T. guajavae and T. lantanae differ from those of T. hoelmeri and T. hyptisemoryi by their shorter submarginal setae (see Table 3), and second and third instar nymphs, as well as third instar nymph of T. salsolae, by the absence of submarginal papillae and marginal button-like structures (Figs 256, 257, 259, 260, 268) that are present in T. hoelmeri and T. hyptisemoryi (Figs 262–264, 267). The third instar nymph of T. salsolae can be recognized from those of T. guajavae and T. lantanae by its longer T2 and T3 setae and shorter caudal setae, much larger size (see Table 3) and presence of four petal-shaped lateroapical projections on VO (Fig. 270), which are lacking in the latter two species (Figs 257, 260). All nymphal instars 1–3 of T. guajavae can be recognized from those of T. lantanae by their larger size (see Table 3).
Remarks. Based on the photograph included with the record from Mexico (Carapia-Ruiz 2020b: 6, fig. 9) we believe that the record of T. cecropiae from Oaxaca corresponds to T. guajavae, and T. cecropiae is so far only known from Brazil.
Biology. A species recently introduced in the state, probably from Mexico, found in large numbers in Southern California between 2007 and 2010 probably due to its parasitoids not being originally introduced with it. The scarcity of recent findings might indicate that it is now under biological control.
Distribution. Found outdoors in Orange County and occasionally in Southern California nurseries; recorded from Mexico (as T. cecropiae; Carapia-Ruiz 2020b).
