Tiphia palmi Krombein, 1938:187 [new name for T. rufipes Smith, not Latreille, 1797].

Tiphia (Tiphia) rufipes Smith.—Allen, 1969:396–398 [type redescription]; 1975:63, 64 [description].

Tiphia palmi is the fifth species in which the mid and hind tibiae of the female are inflated. That sex is distinguished by its small size (5.9–7.0 mm long), relatively sparse punctation, the lack of a median groove on inner surface of the hind basitarsus, the lack of a submarginal carina on the dorsal propodeal surface, entirely light red legs except coxae, hind tibia only twice as long as wide, and the glossy pygidial apex. The male also has light red legs, the second submarginal cell extends as far toward the wing apex as the marginal cell, the mandible lacks a preapical denticle, and the margin of the clypeal lobe is truncate or slightly emarginate.

The species occurs throughout the Indian subcontinent. Within Sri Lanka it occurs in both the Dry Zone and the Wet Zone and at altitudes ranging from sea level to 1000 ft.

FEMALE.—Length 5.9–7.0 mm. Black, the following light red: mandible except base and apex, flagellum beneath, posterior margin of pronotal disk, tegula, legs except coxae; mid and hind tarsi occasionally brown. Vestiture white. Wings faintly infumated, stigma black, veins brown.

Head width 1.5–1.6 times interocular distance at anterior ocellus; clypeal lobe slightly convex, apical margin gently convex, angles rounded, 1.4 times as wide as antennal fossa; lower front without median carina, many punctures separated by half the width of a puncture; upper front with a narrow smooth vitta in front of anterior ocellus, sometimes with 2 impunctate interspaces as wide as an ocellus, punctures a bit more separated than on lower front.

Pronotal disk anteriorly with weak transverse ridge, disk mostly subcontiguously punctate except for smooth apical area which is two-thirds as wide as disk in middle and a fifth as wide laterally; lateral surface with weak to evanescent oblique groove across middle, upper area obliquely and closely aciculate, lower area obliquely lineolate and punctate along anterior margin; scutum with anterior escarpment complete, extending to notauli, posterior half of scutum subcontiguously punctate, laterally and anteriorly with punctures separated by at least half the width of a puncture; tegula transparent, length and width subequal; mesopleuron with subalar patch densely micropunctate and as wide as tegula, anterior half of pleuron with punctures separated by the diameter of a puncture or less, posterior half with crowded small punctures; mid and hind tibiae inflated, twice as long as wide; inner surface of hind tibia not ridged, sensorium small, oval, not impressed; inner surface of hind basitarsus without median groove; propodeal areola tricarinate, median carina extending to apex or almost so, basal width 1.4–1.7 times apical width and 0.6–0.7 times the length, lateral area glossy with a few scattered punctures except denser posterolaterally and weakly roughened anterolaterally, submarginal carina lacking; posterior propodeal surface with small, rather dense punctures, median ridge lacking; lateral propodeal surface obliquely rugulose on upper and posterior areas, the rugulae more separated than in T. kurczewskii, new species, anterior lower area delicately shagreened.

Preapical impression of first abdominal tergum usually 1 puncture wide across middle, though occasionally 2 punctures wide; pygidium on anterior half with sparser elongate punctures and sometimes a small medioapical smooth spot, posterior half smooth and glossy.

MALE.—Length 4.1–5.7 mm. Coloration as in female except clypeal lobe sometimes red in middle. Vestiture white, tinged slightly with yellow on apical abdominal segments. Wings clear, stigma black, veins brown.

Head width 1.5–1.7 times interocular distance at anterior ocellus; median lobe of clypeus almost flat, apical margin subtruncate to slightly emarginate, angles rounded, 1.8 times as wide as antennal fossa; lower front without median ridge and with contiguous small punctures; upper front with a small smooth area below anterior ocellus but no other impunctate interspaces as wide as an ocellus, with small punctures separated by width of a puncture except laterally where they are closer.

Pronotal disk with a rather weak anterior ridge, rugulae behind it weak or evanescent, punctures anteriorly small and mostly separated by half the diameter of a puncture, posterior area of disk impunctate on posterior third in middle and posterior fourth laterally; scutum with punctures separated by half the width of a puncture except anterolaterally where they are sparser; tegula transparent, 1.2–1.3 times as long as wide; mesopleuron with small punctures on anterior half separated by half the width of a puncture and by about the width of a puncture on posterior half; forewing with second submarginal cell extending as far as or almost as far as the marginal cell toward apex; hind tibia without a median ridge on inner surface; propodeal areola tricarinate, median carina extending almost to apex, basal width 1.5–1.8 times apical width and 0.9 times the length, lateral area glossy and smooth except roughened anterolaterally, submarginal carina lacking; posterior propodeal surface with numerous small punctures, median ridge lacking; lateral propodeal surface with stronger, more separated rugulae on posterior and upper areas than in T. kurczewskii, anterior area glossy.

First abdominal segment 1.0–1.1 times as long as wide; first tergum without anterior ridge, preapical impression moderately deep, usually 2 punctures wide across middle; posterolateral process of fifth sternum short, weak or evanescent, oblique; sixth sternum without median tuft of dense suberect hair.
