Diagnosis.

The number of antennomeres in this species, 15, provides a simple means of separating it from other members of the genus. In P. plurima and P. torquata the 6th metasoma tergites and sternites are distinctly the longest. In the absence of antennal characters, these species can be separated on the form of the notaulus, which expands in width posteriorly in P. plurima and is of uniform width in P. torquata .

Description.

Head: Number of antennomeres in female: 15. Number of clavomeres in female: 9. Claval formula in female: 1-2-2-2-2-2-2-2-1. Number of mandibular teeth: 3 on right mandible, 2 on left mandible. Number of labial palpomeres: not visible. Number of maxillary palpomeres: 4. Shape of clypeus: narrow, transverse. Central keel: present. Antennal scrobe: indicated by transverse rugae. Anterior margin of occipital carina: crenulate.

Mesosoma: Pronotal prespiracular depression: present, striate. Netrion: present. Skaphion: absent. Posterior notaulus: not reaching posterior margin of mesoscutum. Width of notaulus: expanding posteriorly. Parapsidal lines: absent. Mesoscutal suprahumeral sulcus: indicated by short line of cells. Scutoscutellar sulcus: simple. Postacetabular carina: present as short ridge laterally, carinae not meeting medially. Postacetabular sulcus: present as simple furrow. Mesopleural epicoxal sulcus: present. Episternal foveae: absent. Metapleural sulcus: present, anterodorsal portion comprised of cells. Lateral propodeal carina: present and continuous dorsally, forming lamella surrounding metasomal depression.

Metasoma: Horn on T1 in female: absent. Sculpture of T1: longitudinally striate medially. Macrosculpture of T2-T5: longitudinal median carina on T2 and T3, otherwise absent. Anterior tergal depressions: visible on T1-T6. Median keel on S2: present. Macroculpture of S3-S6: longitudinal median carina on S3-S4, otherwise absent. Anterior sternal depressions: visible on S1-S5.

Etymology.

The epithet " Proterosceliopsis plurima ", meaning “abundant” or “numerous”, refers to the number of antennomeres in this species, which is the greatest known in Platygastroidea .

Comments.

The number of clavomeres is here coded as 9, a basiconic sensillum on A15 is visible, as are paired sensilla on A14-A8
