Aneflomorpha crypta Lingafelter View in CoL , new species

( Fig. 1e View Figure 1 , 5e View Figure 5 , 7e View Figure 7 , 8d View Figure 8 , 9d View Figure 9 , 10e View Figure 10 , 12a,b View Figure 12 )

Diagnosis. Antennae carinate ( Fig. 9d View Figure 9 ). Spine of third antennomere distinctly longer than second antennomere, projecting away from antennal plane by less than 45 degrees, acute at apex ( Fig. 9d View Figure 9 ). Pronotum with pronounced punctures unobscured by pubescence, sometimes with small, matte, impunctate, post-median callus ( Fig. 5e View Figure 5 ). Elytral apices truncate to very weakly bidentate ( Fig. 8d View Figure 8 ). Elytral pubescence semitranslucent to white or offwhite, recumbent and recurved, with a few scattered long erect to suberect setae ( Fig. 7e View Figure 7 ). Procoxal cavities nearly closed by broadly expanded prosternal process ( Fig. 10e View Figure 10 ).

Description. Length 7–10 mm. Integument dark rufous to piceous. Head with sparse, short, recurved, recumbent, semitranslucent setae mostly each mostly arising from a separate puncture; a few longer, erect setae present on vertex. Interantennal impression weak; antennal tubercles rounded and not strongly elevated. Gula semi-rugose with sparse punctures and setae. Antennae extending beyond elytral apices by 1–2 antennomeres; last antennomere 1.2 times length of penultimate in male with weak constriction at apical third; slightly shorter and less constricted in female. Antennomere four of both sexes slightly shorter than three and five. Antennomere three with acute apicomesal spine about 1.5 times length of antennomere two, projecting away from antennal plane by less than 45 degrees; smaller acute spine on antennomere four that is shorter than antennomere two; very short spine on antennomere five; dentiform on antennomere six. Antennomeres distinctly carinate dorsomesally on three through five, less pronounced on successive antennomeres. Antennomeres of subequal width subbasally and apically; not produced apicolaterally. Antennae with dense but inconspicuous, short, appressed pubescence with scattered, sparse, longer, suberect setae ventro-mesally and apically on most antennomeres. Pronotum dark rufous; distinctly longer than wide (average 1.18 times longer than wide); slightly wider at middle and evenly rounded at sides except for anterior and posterior constrictions; anterior and posterior ends of equal width; much narrower than base of elytra. Pronotum with sparse, short, recurved, recumbent, semi-translucent to white setae, each mostly arising from a separate puncture and not obscuring them; most punctures pronounced, contiguous; relatively larger and deeper than those of elytral base; vague, small posteromedian impunctate callus sometimes present. Prosternum dark rufous, irregularly punctate at posterior three-fourths and base of prosternal process; smooth and coarsely rugose at anterior fourth. Prosternal intercoxal process narrow between procoxae; arcuately declivous and broadly expanded at apex, nearly closing procoxal cavities posteriorly. Mesosternum dark rufous, sparsely punctate, with anterior collar undivided at middle. Metasternum dark rufous to piceous, shallowly punctate. Elytra dark rufous, together average 3.93 times longer than wide ( Fig. 1e View Figure 1 ); with sparse, uniformly distributed, semitranslucent to white, short, recurved, recumbent setae, each arising out of a separate, distinct, mostly noncontiguous puncture. Elytral apices subtruncate to very weakly bidentate. Scutellum broadly rounded posteriorly, with sparse to moderate appressed white setae. Legs with femora dark rufous, of similar color to elytra and pronotum, tibiae and tarsi slightly lighter in color; short with pro-, meso-, and metafemora progressively longer; metafemora extending to about apex of third ventrite. Femoral pubescence mostly short, sparse, semitranslucent to white, recumbent to suberect, but not recurved. Tibiae with scattered, longer, erect setae in addition to shorter, semi-recumbent setae. Femoral apices rounded mesad and laterad, without spines. Tibiae cylindrical; only slightly enlarged apically; weakly laterally carinate; not dorsally carinate. Abdomen dark rufous to piceous; last ventrite broad and truncate in males; slightly, shallowly notched medially in females.

Etymology. The name crypta refers to its similarity to, and confusion with, A. minuta and small individuals of A. rectilinea .

Discussion. This species is known only from southeastern Arizona. It is most similar to A. minuta Chemsak due to its small size and proportions. The relatively smooth, sparsely punctate and rugose gula ( Fig. 12a View Figure 12 ) distinguishes it from A. minuta which has the gula densely punctate ( Fig. 12c View Figure 12 ). The pronotum of A. minuta has, in most specimens, a prominent, shiny impunctate post-median callus ( Fig. 3l View Figure 3 ) unlike A. crypta which has, at most, a small, matte, post-median impunctate region ( Fig. 5e View Figure 5 ). These two species are further distinguished by the anterior margin of the mesosternum which is undivided in A. crypta ( Fig. 12b View Figure 12 ) and divided in A. minuta ( Fig. 12d View Figure 12 ); however this character is usually visible only through dissection and partial clearing. Specimens of A. crypta have legs rufous and very similar to the overall ventral coloration unlike A. minuta which have pale testaceous legs that are distinctly lighter in color from the venter of the pro- and mesothorax, at least. The spine of the third antennomere in A. crypta is more acute at the apex than specimens examined of A. minuta . The leg color and antennal spine characters should be used with caution since larger series could reveal variability as has been seen in some specimens of other species.

Aneflomorpha crypta is similar in size to small examples of A. cazieri . Most specimens of A. cazieri are easily distinguished by the blunt spine of antennomere three. For those specimens of A. cazieri without a very blunt spine on antennomere three, the presence of a basal antennal carina on antennomere three ( Fig. 9d View Figure 9 ) in A. crypta will distinguished it from A. cazieri which lack antennal carinae ( Fig. 9b View Figure 9 ). The open procoxal cavities of A. cazieri ( Fig. 10c View Figure 10 ) which are closed (or very nearly so) in A. crypta ( Fig. 10e View Figure 10 ) aid in distinguishing them. Both have a similar weakly punctate gular region, but in that region punctation is limited to the anterior half in A. crypta ( Fig. 12a View Figure 12 ) and extends to the posterior margin of the lower eye lobes in A. cazieri (as in Fig. 12c View Figure 12 ). The anterior margin of the mesosternum is undivided at the middle in A. crypta ( Fig. 12b View Figure 12 ) and divided in A. cazieri (as in Fig. 12d View Figure 12 ). The pronotum of A. crypta typically has sparse, inconspicuous setae on the disk, exposing large, separate punctures of nearly same size as those on elytral base ( Fig. 5e View Figure 5 ), while in A. cazieri , the pronotum usually has the setae more prevalent, partially concealing punctures that are mostly smaller than those of the elytral base ( Fig. 5c View Figure 5 ).

This species might also be confused with small examples of A. rectilinea , but it can be distinguished by the less strongly carinate antennae ( Fig. 9d View Figure 9 ) which are boldly carinate in A. rectilinea ( Fig. 9o View Figure 9 ) and the less distinctly pubescent pronotum with the punctures exposed ( Fig. 5e View Figure 5 ) unlike most A. rectilinea which have denser pronotal setae that obscure many punctures ( Fig. 6q, r View Figure 6 ). Further, most A. rectilinea have strongly bidentate or weakly bispinose elytral apices unlike A. crypta which have the apices truncate or very weakly bidentate. Another character that distinguishes them is the anterior collar of the mesosternum which is divided in A. rectilinea ( Fig. 12e View Figure 12 ) and undivided in A. crypta ( Fig. 12b View Figure 12 ).

Distribution and biology. All specimens have been collected at ultraviolet and mercury vapor lights in July and August at the base of the Huachuca Mountains in Arizona at an elevation of 1500 meters (pers. obs.). The larval hosts are unknown, however the immediate habitat where adults have been collected is dominated by Emory oaks ( Quercus emoryi Torr. ) and Arizona Blue oaks ( Quercus oblongifolia Torr. ), and it is presumed that one, or both, of these trees are the larval host plant.
