A common medium-sized vivid blue species similar in appearance to the more northerly
Argia extranea
(Hagen)
.
Description of male
holotype
. Head (
Fig. 17
): Labrum, ante- and postclypeus, ante- and postfrons, base of mandibles and genae blue; base of postfrons with black inverted T connecting to black on epicranium, the latter interrupted by large blue postocular spots each broadly confluent with compound eyes, blue occipital bar interrupted forming three spots, two lateral, the third one a small crossbar medially, a small triangular blue spot anterolateral to lateral ocellus and a small longitudinal blue spot between lateral ocelli; antennae black; rear of head pale except for wash of brown on each side of occipital foramen.
Prothorax black with following areas blue: anterior lobe, dorsolateral spot on middle lobe, narrow elongate diagonal spot on lateral portion of propleuron with posterior margin rimmed in black. Pale areas of pterothorax vivid blue, with black middorsal stripe slightly narrowed at basal 0.20, about as wide as blue antehumeral stripe; anterior half of mesinfraepisternum black, continuous with broad humeral stripe at base then abruptly narrowing at basal fifth along mesopleural suture then abruptly forming a thin hairline at 0.50 before expanding again at mesopleural fossa; remainder of thorax blue except for narrow black stripe on metapleural suture (
Fig. 17
). Wings hyaline with venation black; pterostigma dark brown, surmounting 1 cell in all wings; postnodals Fw 15/16, Hw 15/14; postquadrangular cells Fw 4/4, Hw 3/3; RP2 at Fw 7/7, Hw 5/5.5. Coxae and trochanters pale except for black on dorsum of trochanters; femora black, interior surface pale; tibiae black with extensor surface pale, tarsi and armature black.
Abdomen (
Figs. 17
,
63
) mostly blue; S1 blue with a narrow irregular black ring basally; S2 blue with an irregular black lateral stripe ending at apical 0.25, its anterior end connecting as a narrow black ring above, its posterior end sending a narrow triangular offshoot dorsally but connecting above, annulus black; S3 blue, ventrally with broad black stripe beginning at basal 0.10 and interrupted at dorsal margin at distal 0.60 by a narrow elongate blue spot, lateral black stripe extending dorsally at apical 0.20 and connecting dorsally isolating small blue middorsal and lateral spots posteriorly before black annulus; S6–7 similar but blue with no isolated posterior middorsal blue spot; S7 with broad black lateral stripe not interrupted medially; S8–9 blue with incomplete lateral black stripe below, posterior margin of S10 rimmed in black up to torus and with a complete narrow black middorsal stripe connecting basally with a narrow black ring; torus pale, its ventral margin rimmed with black; cercus brown; paraproct blue dorsobasally, remainder black.
Genital ligula (as in
Fig. 132
) ending in a triangular apical lobe, laterally with a small posteriorly directed lobe at basal 0.50 (as in
Fig. 132
b); apical portion of genital ligula slightly concave entally (as in
Fig. 132
c) and lacking any accessory structures; lateral sclerotized portion proximal to flexure lacking a microspinulate patch on ental surface on each side.
Torus large, swollen, transversely oval, occupying entire ventral margin of torifer but not overlapping bilobed epiproct (
Fig. 151
a); epiproct pale, black laterally; cercus quadrate in dorsal view with outer margin about twice the length of inner margin (
Fig. 151
c); in mediodorsal view dorsal surface slightly concave with a broadly based distal tooth at basal 0.50 (
Figs. 151
a, d); in lateral view narrowly triangular, about half length of paraproct (
Fig. 151
b); paraproct deeply forked, dorsal branch forming a broadly based triangle; ventral branch narrow, digitiform, meeting dorsal branch at a right angle, about 1.5 times as long as dorsal branch, its tip slightly curved mesad (
Fig. 151
a).
Dimensions
. Hw 22.7, abdomen 28.6, total length 37.2.
Description of female
paratype
(
Honduras
:
Cortés
Dept.: Santo Tomás Camp, river behind camp, muddy, on low vegetation, Cusuco National Park,
Figs. 39, 40
,
89
). Similar to male but pale colors light olive tan. Head, pro-, pterothorax as in male but with pale color on S1–2 more extensive; legs largely tan with streaks of brown on outer surfaces of femora and inner portion of tibiae at distal 0.40; S1–2 similar to male but pale coloration more extensive; S3–6 pale with a complete narrow ventral stripe and above an isolated elongate postbasal streak followed by a shorter apical spot that dorsally connects above; these stripes becoming more extensive on succeeding segments with postbasal and apical lateral spots connecting with ventral stripe; S7 (
Fig. 89
) mostly black except for narrow pale basal ring and vestiges of a pale lateral stripe; S8–10 pale except for small apical spot laterally on each segment; cerci black; ovipositor pale, sternite 8 and ovipositor pale rimmed with black dorsally and ventrally.
Mesostigmal lobe forming a low evenly raised lobe continuous with distal margin of plate; in anterior view, lobe forming an elongate raised lobe (
Figs. 111
a, b); an elongate raised tubercle posterior to plate at junction with mesepimeron when viewed posteriorly (
Fig. 111
e) an elongate depressed area paralleling medial portion of mesostigmal lobe on anterior portion of mesepisternum when viewed dorsally (
Figs. 111
c, d).
Variation in paratypes
. Both sexes vary as to extent of dark markings on thorax and especially abdomen. The humeral stripe in both sexes is usually as depicted in
Fig. 17
but in rare instances the humeral stripe is forked above (as in
Fig. 22
) in males (Chiapas State, canyon below Ixhuatan, 2.7 SW of Unión Juarez) or the posterior fork is present but isolated (as in
Fig. 21
; El Salvador: Santa Ana Dept., El Limo Ranch); five other males (Panama: Cero Azul; Finca Hartmann; Bambito, Mata Ahogado; El Valle de Antón) have the upper hairline portion of the humeral stripe thickened (as in
Fig. 21
), but all of these conditions are rare. Extent of black markings on S7–10 is variable, ranging from a thin linear stripe on basal 0.70 of S7 (
Fig. 66
) to a more normal broad stripe (
Figs. 63–65
); ventral black on S8–
9 may
occasionally be absent (
Figs. 65, 66
). Pterostigma surmounting 1–2 cells in males,
1–1.5 in
females; postnodals: Fw 12–17, Hw
10–15 in
males, Fw 13–18, Hw
11–15 in
females; postquadrangular cells Fw 3–4, Hw
3 in
males, Fw 4, Hw
2–3 in
females; RP2 at Fw 6–8, Hw
5–7 in
males and females.
Dimensions
. ♂: Hw 21.9 ± 1.53 [18.8–23.4], abdomen 28.5 ± 1.71 [24.5–30.4], total length 36.6 ± 1.89 [32.2–38.6]. ♀: Hw 22.7 ± 1.7 [20–23.9], abdomen 26.3 ± 1.42 [23.7–29.1], total length 34.2 ± 1.81 [31.2–37.8].
Diagnosis
. This species closely approaches the more northerly
A. extranea
in color pattern (
Figs. 177–180
) and morphology. Both sexes may be separated by the following key:
1. Males...............................................................................................2

Diagnostic characters of the genital ligula and of the placement of the decumbent tooth on the posterior margin of the cercus in males and morphology of the mesostigmal plates in females appear to be reliable diagnostic characters to recognize
A. elongata
and
A. extranea
. The relative length of ventral and dorsal branches of male paraproct and the constriction of the middorsal stripe are more variable and should not be used as the only means of distinguishing between these two species.
Remarks
.
Calvert (1902)
commented on the variability of the paraproct length within
A. extranea
, noting a general increase in length north to south ("...In a general way, it seems that the relative and absolute length of the lower branch of the inferior appendage increases in specimens from north to south, i. e. in those from
Mexico
to
Costa
Rica
...") and in 1907 ("....in the females [of
Argia extranea
] the black middorsal thoracic stripe is frequently narrowed at its lower end....").
Garrison (1994)
, in his account of
A. extranea
, discussed the details surrounding Calvert’s (1902) broader concept of
A. extranea
and suggested that Calvert included an undescribed violaceous species from Texolo as well as noting the possibility that two species (
A. extranea
and
A. elongata
as treated here) might be involved. The more southerly populations (here treated as
A. elongata
) had long been recognized by the late L. K. Gloyd as separate from the more northerly
A. extranea
, for which she applied the manuscript name “
extensa
” to over 1,000 specimens she examined from numerous collections. Our treatment of this species confirms Gloyd’s assertion that
A. elongata
, as treated here, is a closely related species but distinct from
A. extranea
.
Garrison (1994)
listed
Argia mista
Navás
as a junior synonym of
A. extranea
based on M. Westfall’s examination of the holotype of
A. mista
at the MNHN. Through the kindness of Jean Legrand, we have been able to examine the holotype of
A. mista
(
Fig. 153
) as well as the holotype of
Agrion extraneum
Hagen (
Figs. 151
a–d) and can confirm their synonymy. Our distribution records of
Argia extranea
show it to occupy the foothills of the Sierra Madre Occidental, del Sur and Oriental; we have seen no records from the lowland areas bordering the Gulf of Mexico and we suggest that Saussure’s 1854–5 collection of the holotype likely occurred further west than its stated type locality of Tampico.
Garrison and von
Ellenrieder (2015)
discussed the confused applications of the name
extranea
to various South American species described by
Fraser (1946)
.
Habitat
. Rocky to muddy rivers and streams and open areas near trickles and ponds, in primary forest to disturbed habitats.
Argia elongata
is the most common species of
Argia
to be found within its range. Specimens have been collected year round at various localities at elevations ranging from near sea level (
Mexico
: Agua Caliente) to over
2,000 m
(
Mexico
: steep ridge above Siltepec on road to El Porvenir). This species is primarily an inhabitant of the moist foothills of the Sierra Madre Occidental, del Sur, and Oriental occurring at altitudes over
100 m
.
It appears to be absent from the central plateau (Altiplanicia Mexicana). Of over 300 localities recorded, only eight yielded collections under
100 m
.

Distribution
.
Argia elongata
shows an allopatric distribution with its close relative
A. extranea
, extending from Veracruz and Oaxaca states in S Mexico south to Panama (
Fig. 167
), while
A. extranea
extends from the Los Tuxtlas region of central Veracruz and Oaxaca states north to Arizona in SW USA (
Fig. 167
). Selys (1865) lists
A. extranea
from Colombia (probably by Nicholas Funck) and Surinam (by Robert H. Schomburgk), but we have seen no specimens of
A. elongata
from South America. The Colombian record, if by Funck, likely corresponds to incorrectly labeled specimens as to locality, as discussed by González-Soriano and von
Ellenrieder (2009)
, and the specimen from Surinam is probably a misidentification (
Belle 2002
).
