Aphanogmus albicoxalis
Evans and Dessart
,
n. sp.
(
Figs. 1–6
).
Diagnosis
Aphanogmus albicoxalis
n. sp.
is placed in the
fumipennis
group based on the presence of a longitudinal mesoscutal furrow and basal carina on the first gastral tergite. It differs from other species in the genus by its white hind coxae; no other species in this genus are known to have white or clear hind coxae, although species with similarly colored hind coxae are known in other genera of the superfamily.
A. albicoxalis
also differs from other species of the
fumipennis
group by having a subapical carina that connects the lateral carinae of the scutellum (
Fig. 2
). Certain species in the
fumipennis
group have the lateral carina ending in an ellipse, but in
A. albicoxalis
it is separated from the peripheral carina.
Description
Holotype
female
(
Figs. 1–4
).
Color:
Body dark brown to black, gaster usually slightly lighter than head and thorax; antennal scape light brownish yellow; pedicel and flagellum dark brown; legs light brown, except white hind coxae and fore and middle tibiae which are relatively darker brown; wings hyaline, slightly infuscate basally on the posterior margin.
Body
. Length:
1420 m
. Head length/width/height 255/415/375; eyetorulus: 80; eye length/width: 260/200; DFIm (minimal interocular facial distance) 40–42% of the head width; preoccipital lunule limited anteriorly by a sharp edge, well separated from the posterior ocelli, and laterally fusing with the orbits; preoccipital furrow linear, surpassing the anterior edge, and not terminating in the intraocellar pit; ocellar triangle almost a right angle, POL/ LOL/OOL measurements: 135(60)/80(40)/45, where the maximum distance is the first number, followed by the minimal distance in parentheses; LOL slightly longer than the axis of the posterior ocellus; posterior ocelli flanked with a very narrow external lunule, anterior ocellus preceded by a large pit with a cover over the pit that is observed using diffused light.
Antenna
(
Fig. 4
). Length/width ratios: scape (233/55), pedicel (82/33), F1 (33/27), F2 (36/27), F3 (33/38), F4 (33/44), F5 (27/49), F6 (47/52), F7 (47/49); club, 3segmented (110/55).
Mesosoma
(
Figs. 2 & 3
). Longitudinal mesoscutal furrow present; posterior margin unarmed, without spurs and with transverse carina slightly extending beyond scutellar apex; (length/width/height): 480/320/455; mesoscutum (length/width): 180/415; axilla (length): 40; scutellum (length/width) 195/145, very convex with lateral carinae joining separately the peripheral margin of the scutellum before its apex, but interconnected sub apically by a thin transverse carina, which may give the impression that the lateral carinae end in preapical ellipse; metanotum (length at center) 10; propodeum (length at center of dorsum): 15; mesepimeron, side of pronotum clearly depressed anteriorly, alutaceous behind the furrow, without the hind branch or forming a "Y" and practically bent at right angle; mesopleuron and metapleuron fused (without mesopleurometapleural furrow), upper part covered with fine striae, interspersed with fine reticulations; mesopleuron with an smooth area adjacent to carina which separates it from the venter.

1) female forewing, 2) female mesosoma 3) female habitus, 5) female antenna, 5) male genitalia, 6) male antenna.
Fore wing
(
Fig. 1
). Length (877), width (274), disc length (329), width 0.84x disc length, stigmal vein elongate (170), marginal vein divided, distal part (110) shorter than basal part (206) and costal cell (234); submarginal vein with 6 setae; marginal vein with 12 + 6 setae along the anterior margin; wing with uniformly spaced long setae; longest seta of marginal fringe (27), 0.1x forewing width.
Metasoma
(
Fig. 3
). Length/width/breadth: 680/320/185; large tergite (T3): 365 slightly over half gastral length), with basal carina present.
Allotype
male
(
Figs. 5–6
).
Similar to female in coloration and structure, except antennae entirely yellowish brown and generally body smaller in size. Length/width measurements of antennal segments (
Fig. 6
): scape (241/58), pedicel (82/44), F1 (132/41), F2 (101/44), F3 (93/41), F4 (96/47), F5 (96/47), F6 (99/55), F7 (96/58), F8 (93/55); F9 (club), 1segmented (145/41); genitalia shown in
Fig 5
